Resumen: Objetivo: El tratamiento de la valvulopatía aórtica severa con implante de válvulas transcatéter es una alternativa cada vez más frecuente. Presentamos nuestra experiencia inicial con la prótesis Portico™ Abbott en el Centro Médico Teknon de Barcelona. Pacientes y métodos: Entre febrero de 2020 y junio de 2021 la prótesis aórtica transcatéter Portico™ Abbott se implantó en 30 pacientes (edad media: 75,7 ± 3,1 años, 56,5% varones). Veintinueve fueron implante valvular aislado. En un paciente se realizó además revascularización coronaria. La vía de acceso fue abierta; transfemoral en 22 pacientes (73,3%), transaxilar en 4 (13,3%) y transcarotídea en 4 (13,3%). Los pacientes fueron estudiados al alta y a los 30 días. Resultados: Éxito del implante en el 100% de los pacientes. Un paciente (3,3%) falleció durante el procedimiento por shock cardiogénico. No hubo complicaciones vasculares ni neurológicas. En 3 pacientes (10.3%) fue necesario implantar un marcapasos definitivo. Hubo fuga mínima residual en 10 pacientes (33,3%) y ligera en 7 (23,3%). El gradiente medio transprotésico fue de 5 ± 0,8 mmHg en válvulas nativas y de 10,25 ± 2,2 mmHg en valve-in-valve. La estancia en UCI fue de 22,56 ± 4 h y la estancia global de 4,1 ± 0,8 días. Control a los 30 días sin otras complicaciones. Conclusiones: La prótesis transcatéter Portico™ Abbott ha resultado factible, eficaz y muy versátil para adaptarse a escenarios muy variados y de alta complejidad técnica. Las complicaciones han sido bajas, el resultado satisfactorio y el comportamiento hemodinámico precoz excelente. Abstract: Objective: Transcatheter aortic valve implantation is a good alternative for treatment of severe aortic valvulopathy. We present our initial experience with the Portico™ Abbott prosthesis at Centro Médico Teknon in Barcelona. Patients and methods: Between February 2020 and June 2021, 30 patients underwent Portico™ Abbott transcatheter aortic prostheses implant (mean age: 75.7 ± 3.1 years, 56.5% males). Twenty-nine underwent isolated valve replacement. One patient required associated coronary surgery. The approach was open surgical; transfemoral in 22 patients (73.3%), transaxillary in 4 (13.3%) and transcarotid in 4 (13.3%). The patients were studied at discharge and at 30 days. Results: The implant was successful in 100% of the patients. One patient (3.3%) died during the procedure due to cardiogenic shock. There were no vascular or neurological complications. In 3 patients (10.3%) it was necessary to implant a permanent pacemaker. Minimal residual leak in 10 (33.3%), mild in 7 patients (23.3%). Mean gradient: 5 ± 0.8 mmHg in native valves and 10.25 ± 2.2 mmHg in valve-in-valve cases. ICU stay 22.56 ± 4 h and post-procedure stay 4.1 days ± 0.8. Follow-up at 30 days without other complications. Conclusions: In our initial experience, the Abbott™ Portico prosthesis has proven to be feasible, very effective and very versatile to adapt to scenarios of high technical complexity. The complications were low, the results satisfactory and the early haemodynamic performance excellent.

This study sought to evaluate the impact of virtual reality (VR) tools in procedural planning of transcatheter aortic valve replacement. A prospective study involving 11 patients referred for transcatheter aortic valve replacement was conducted. A multidetector computed tomography was used to acquire and segment the anatomy of the access route and landing zone. From the information obtained with the multidetector computed tomography in DICOM format, we built a virtual platform (VisuaMed, Techer Team, Valencia, Spain) that contains all the clinical information of the patients and a virtualized model of their anatomy. Wearing VR devices, the professional was able to ‘walk inside’ the anatomy in an interactive and immersive way. Decisions after the evaluation of routine clinical images were compared with those after experience with VR models and intraprocedural findings.

Objective To define the benefit of sutureless and rapid deployment valves in current minimally invasive approaches in isolated aortic valve replacement. Methods A panel of 28 international experts with expertise in both minimally invasive aortic valve replacement and rapid deployment valves was constituted. After thorough literature review, the experts rated evidence-based recommendations in a modified Delphi approach. Results No guideline could be retrieved. Thirty-three clinical trials and 9 systematic reviews could be identified for detailed text analysis to obtain a total of 24 recommendations. After rating by the experts 12, final recommendations were identified: preoperative computed to-mographic scan as well as intraoperative transesophageal echocardiography are highly recommended. Suitable annular sizes are 19 to 27 mm. There is a contraindication for bicuspid valves only for type 0 and for annular abscess or destruction due to infective endocarditis. The use of sutureless and rapid deployment valves reduces extracorporeal circulation and aortic cross-clamp time and leads to less early complications as prolonged ventilation, blood transfusion, atrial fibrillation, pleural effusions, paravalvular leakages and aortic regurgitation, and renal replacement therapy, respectively. These clinical outcomes result in reduced intensive care unit and hospital stay and reduced costs. The use of sutureless and rapid deployment valves will lead to a higher adoption rate of minimally invasive approaches in aortic valve replacement. Respect should be taken to a necessary short learning curve for both sutureless and minimally invasive programs. Conclusions Sutureless and rapid deployment aortic valve replacement together with minimally invasive approaches offers an attractive option in aortic valve placement for patients requiring biological valve replacement.

Because of the clinical significance of carotid atherosclerosis, the search for novel biomarkers has become a priority. The aim of the present study was to compare the protein secretion profile of the carotid atherosclerotic plaque (CAP, n = 12) and nonatherosclerotic mammary artery (MA, n = 10) secretomes. We used a nontargeted proteomic approach that incorporated tandem immunoaffinity depletion, iTRAQ labeling, and nanoflow liquid chromatography coupled to high-resolution mass spectrometry. In total, 162 proteins were quantified, of which 25 showed statistically significant differences in secretome levels between carotid atherosclerotic plaque and nondiseased mammary artery. We found increased levels of neutrophil defensin 1, apolipoprotein E, clusterin, and zinc-alpha-2-glycoprotein in CAP secretomes. Results were validated by ELISA assays. Also, differentially secreted proteins are involved in pathways such as focal adhesion and leukocyte transendothelial migration. In conclusion, this study provides a subset of identified proteins that are differently expressed in secretomes of clinical significance.

OBJECTIVES: The development of new percutaneous and surgical techniques has reduced the risk associated with aortic valve replacement procedures. We present the results of a Spanish register after initiating a programme for sutureless prostheses in moderatehigh-risk patients. METHODS: This prospective multicentre study was carried out from November 2013 to November 2016. Data were obtained from 448 patients in whom a Perceval S prosthesis was implanted. RESULTS: The mean age was 79.24 (standard deviation [SD] 4.1) years, and 61.2% were women. The estimated EuroSCORE I log risk was 11.15% (SD 7.6), with an observed mortality of 4.4% (20 patients). Isolated aortic valve replacement was performed on 69.26% of patients, with 64% involving ministernotomy. The incidence of neurological events was 2%, with 2 permanent cerebrovascular accidents, and 41 (9.2%) patients were implanted with a permanent endocavitary pacemaker. At discharge, 12 (2.6%) patients presented minimal periprosthetic leakage, and 4 (0.89%) patients had moderate leakage. There were 3 reinterventions during follow-up (2 endocarditis and 1 dysfunction due to periprosthetic leak progression). The mean gradient at discharge, 6 months and 1 year was 12.94 (SD 5.3) mmHg, 12.19 (SD 4.7) mmHg and 11.77 (SD 4.7) mmHg, respectively; 59.4% of the patients were octogenarians, with a survival rate of 98% at both 6 months and 1 year at discharge. There was neither valve migration nor early structural degeneration. The mean follow-up was 12 ± 3 months. The 6-month and 1-year mortality was 1.4% and 2.1%, respectively. CONCLUSIONS: This is a prospective multicentric study on the largest cohort of patients with sutureless valves conducted in Spain to date. It is a reproducible procedure that has enabled surgery on patients with a moderatehigh risk with low morbidity and mortality, providing good haemodynamic results.

Introduction and objectives Current postoperative management of adult cardiac surgery often comprises transfer from the intensive care unit (ICU) to a conventional ward. Intermediate care units (IMCU) permit hospital resource optimization. We analyzed the impact of an IMCU on length of stay (both ICU and in-hospital) and outcomes (in-hospital mortality and 30-day readmissions) after adult cardiac surgery (IMCU-CS). Methods From November 2012 to April 2015, 1324 consecutive patients were admitted to a university hospital for cardiac surgery. In May 2014, an IMCU-CS was established for postoperative care. For the purposes of this study, patients were classified into 2 groups, depending on the admission period: pre-IMCU-CS (November 2012-April 2014, n = 674) and post-IMCU-CS (May 2014-April 2015, n = 650). Results There were no statistically significant differences in age, sex, risk factors, comorbidities, EuroSCORE 2, left ventricular ejection fraction, or the types of surgery (valvular in 53%, coronary in 26%, valvular plus coronary in 11.5%, and aorta in 1.8%). The ICU length of stay decreased from 4.9 ± 11 to 2.9 ± 6 days (mean ± standard deviation; P

Resumen Fundamento y objetivo La reparacion valvular mitral es el tratamiento de eleccion de la insuficiencia mitral degenerativa. Sin embargo, no esta tan clara su indicacion en el caso de insuficiencias mitrales (IM) secundarias a endocarditis infecciosas (EI), particularmente cuando se intervienen durante su fase activa. Si bien varios estudios observacionales han mostrado la superioridad de la reparacion con respecto a la sustitucion mitral en pacientes sometidos a cirugia de EI, en la mayoria de los centros se sigue optando por la sustitucion valvular por su facilidad y reproducibilidad tecnica. Exponemos a continuacion la experiencia de nuestro centro. Pacientes y metodo Se trata de 4 pacientes intervenidos recientemente durante la fase activa de una endocarditis infecciosa. Se discuten las caracteristicas epidemiologicas y clinicas de cada paciente. Resultados Los 4 pacientes fueron sometidos a distintas tecnicas de reparacion valvular mitral. No se han descrito recaidas ni reinfecciones, y todos los pacientes presentan IM de grado 0 o i / iv en el seguimiento. Conclusiones La reparacion valvular mitral durante la fase activa de la EI es una tecnica factible y que permite obtener buenos resultados postoperatorios.

Background Novel pro-inflammatory and anti-inflammatory derivatives from adipose tissue, known as adipokines, act as metabolic factors. The aim of this study was to analyse the secreted expression of different adipo/cytokines in secretomes of unstable carotid atherosclerotic plaque versus non-atherosclerotic mammary artery. Methods We evaluated the secretion levels of adiponectin, visfatin, lipocalin-2, resistin, IL-6 and TNFR2 by ELISA in human secretomes from cultured unstable carotid atherosclerotic plaque (n = 18) and non-atherosclerotic mammary artery (n = 13). We also measured visfatin serum levels in patients suffering from atherosclerosis and in a serum cohort of healthy subjects (n = 16). Results We found that visfatin levels were significantly increased in unstable carotid atherosclerotic plaque secretome than in non-atherosclerotic mammary artery secretome. No differences were found with regard the other adipo/cytokines studied. Regarding visfatin circulating levels, there were no differences between unstable carotid atherosclerotic plaque and non-atherosclerotic mammary artery group. However, these visfatin levels were increased in comparison to serum cohort of healthy subjects. Conclusions Of all the adipo/cytokines analysed, only visfatin showed increased levels in secretomes of unstable carotid atherosclerotic plaque. Additional human studies are needed to clarify the possible role of visfatin as prognostic factor of unstable carotid atherosclerotic plaque.

OBJECTIVES In high-risk patients with severe aortic stenosis, aortic valve replacement (AVR) with a sutureless Perceval prosthesis (SU-AVR) can be performed instead of conventional AVR or transcatheter aortic valve implantation. Little data are available regarding postoperative conduction disorders after SU-AVR. We aimed to determine the incidence and predictors of new-onset complete atrioventricular block (NO-AVB) requiring permanent cardiac stimulation following SU-AVR. METHODS We studied consecutive patients who underwent SU-AVR between 2013 and 2015. Early patients underwent partial aortic decalcification and subannular valve implantation (standard technique), while later patients underwent complete/symmetrical decalcification and intra-annular valve deployment (modified technique). Predictive baseline and procedural variables and electrocardiographic parameters were identified using a logistic regression model. RESULTS We included 140 patients (mean age, 78 ± 6.5 years; mean Log EuroSCORE II, 8.9 ± 10%; 28.6% concomitant myocardial revascularization). The most common postoperative conduction disturbances were LBBB (25%), NO-AVB (12.1%) and first-degree atrioventricular block (AVB) (7.9%). The incidence of NO-AVB was 61% lower with the modified versus the standard technique (P= 0.04). NO-AVB predominantly appeared within 24 h post-surgery, occurring >24 h post-surgery in only 2 patients (both with baseline conduction defects). Independent predictors of NO-AVB included baseline left QRS axis deviation (LaQD; P= 0.03), first-degree AVB (P< 0.01) and standard surgical technique (P= 0.02). CONCLUSIONS NO-AVB is a frequent complication following SU-AVR, and its incidence strongly depends on the surgical technique. Baseline first-degree AVB and LaQD independently predict NO-AVB and should be considered when deciding the duration of postoperative electrocardiographic monitoring.

The present study evaluates the safety and efficacy of the Adipose Graft Transposition Procedure (AGTP) as a biological regenerative innovation for patients with a chronic myocardial scar. This prospective, randomized single-center controlled study included 10 patients with established chronic transmural myocardial scars. Candidates for myocardial revascularization were randomly allocated into two treatment groups. In the control arm (n = 5), the revascularizable area was treated with CABG and the non-revascularizable area was left untouched. Patients in the AGTP-treated arm (n = 5) were treated with CABG and the non-revascularizable area was covered by a biological adipose graft. The primary endpoint was the appearance of adverse effects derived from the procedure including hospital admissions and death, and 24-hour Holter monitoring arrhythmias at baseline, 1 week, and 3 and 12 months. Secondary endpoints of efficacy were assessed by cardiac MRI. No differences in safety were observed between groups in terms of clinical or arrhythmic events. On follow-up MRI testing, participants in the AGTP-treated arm showed a borderline smaller left ventricular end systolic volume (LVESV; p = 0.09) and necrosis ratio (p = 0.06) at 3 months but not at 12 months. The AGTP-treated patient with the largest necrotic area and most dilated chambers experienced a noted improvement in necrotic mass size (− 10.8%), and ventricular volumes (LVEDV: − 55.2 mL and LVESV: − 37.8 mL at one year follow-up) after inferior AGTP. Our results indicate that AGTP is safe and may be efficacious in selected patients. Further studies are needed to assess its clinical value. (ClinicalTrials.org , AdiFlap Trial). The Adipose Graft Transposition Procedure (AGTP) is a new surgical technique for reducing the scar after a heart attack. It has been evaluated in 10 patients for the first time and has been proved to be safe. This technique consists on the use of the existing fat surrounding the heart that has beneficial properties. The procedure is easy for the surgeons to perform. The next step will be to test the efficacy in a larger population.

Introducción y objetivosLa reparación mitral es el tratamiento de elección de la insuficiencia mitral grave degenerativa por prolapso. El objetivo del estudio es analizar los resultados a medio plazo de la cirugía reparadora mitral.MétodosEstudio prospectivo de pacientes con insuficiencia mitral grave degenerativa, por prolapso de uno o dos segmentos valvulares en los que se realizó cirugía reparadora mitral en nuestro centro (2002–2008). Se practicó valoración clínica y ecocardiográfica precirugía, en la intervención y en el seguimiento.ResultadosSe intervinieron 100 pacientes (edad media 65±12 años, hombres 66%). El estudio ecocardiográfico prequirúrgico nos permitió una correcta identificación de los segmentos valvulares afectos en el 96,3% de los casos. La mortalidad quirúrgica fue del 0% y la postoperatoria del 4%. Durante el seguimiento (mediana 31 meses [1–93) hubo una tasa de pacientes libres de reintervención del 98% al año y del 96% a los 5 años. La supervivencia actuarial fue del 94% al año y del 92% a los 5 años. Ningún paciente operado en CF I-II requirió reintervención, siendo la mortalidad hospitalaria y durante el seguimiento de cero.ConclusionesLa reparación valvular mitral se ha mostrado como una técnica segura y eficaz. Un equipo multidisciplinario permite la correcta identificación de pacientes candidatos y la aplicación de las técnicas quirúrgicas adecuadas. A la espera de un mayor seguimiento, los resultados son satisfactorios.Introduction and objectivesValve repair is the procedure of choice for severe mitral regurgitation due to leaflet prolapse. The aim of this study is to analyze the mid-term results of mitral valve repair.MethodsWe performed a prospective study including patients with severe degenerative mitral regurgitation due to leaflet prolapse (one or two segments) who underwent mitral valve repair during the study period (2002–2008) in our hospital. Clinical and echocardiographic evaluation was performed before surgery, intraoperatively and during the follow-up.ResultsMitral valve repair was performed in 100 patients (mean age 65±12 years-old, 66% males). The accuracy of preoperative echocardio-graphic identification of the prolapsed segments/ scallops was 96.3%. Intraoperative mortality was 0% and hospital mortality 4%. Median follow-up period was 31 months (1–93). Freedom from reoperation at 1 year and 5 years was 98 and 96%. The actuarial survival rate at 1 year and 5 years was 94 and 92%. No patient operated on in NYHA class I-II required a reoperation, being both inhospital and follow-up mortality zero in that group of patients.ConclusionsMitral valve repair proved to be a safe and effective technique. A multidisciplinary team allows a correct patient’s selection and the application of the right surgical technique. Awaiting for longer follow-up results are satisfactory.

Background The aim of the study was to analyse the presence of several metabolites related to atherosclerosis in the plasma of patients with unstable carotid plaque and in the plasma of healthy subjects. Materials and methods We included 20 patients who had undergone carotid endarterectomy and 20 healthy subjects as a control group. All the subjects recruited were male. We used a metabolomic approach with liquid chromatography coupled to mass spectrometry to evaluate plasma metabolite levels in the metabolic pathway involved in the progression of atherosclerotic plaque. Results We observed that circulating levels of 20-HETE were significantly higher in patients with atheroma plaque than in healthy subjects (p = 0.018). No differences were found with regard to the other metabolites analysed. We also conducted a random forest analysis and found that 20-HETE was the main differentiator in the list of selected metabolites. In addition, plasma levels of 20-HETE correlated positively with body mass index (r = 0.427, p = 0.007) and diastolic blood pressure (r = 0.365, p = 0.028). Conclusion This study confirms that of all the molecules studied only 20-HETE is related to carotid plaque. Further studies are needed to compare patients with stable carotid plaque vs. patients with unstable carotid plaque in order to confirm that 20-HETE could be a potential factor related to carotid plaque.

Introduccion y objetivos El incremento del intervencionismo percutaneo ha conllevado una disminucion significativa de la cirugia coronaria. El perfil del paciente coronario que se remite a cirugia es mas anoso, con mayor comorbilidad, peor funcion ventricular y con procedimientos percutaneos previos. En este sentido la cirugia ha intentado mejorar sus resultados desde varios frentes de actuacion. El objetivo es analizar y describir la experiencia inicial de la cirugia coronaria con mini-circulacion extracorporea (MCEC) en un grupo de cirugia cardiaca en el que se ha convertido en tecnica de eleccion. Metodos Entre enero de 2004 y abril de 2007, se analizo de forma retrospectiva a 408 pacientes sometidos a cirugia coronaria aislada con MCEC, 329 (80,6%) varones, con media (intervalo) de edad de 63,5 (28-83) anos. Un 63% tenia hipertension; el 49,3%, diabetes; el 69%, dislipemia, y el 52% eran fumadores. Resultados El EuroSCORE logistico (mortalidad esperada) era del 3,7% (1%-38%). El 34% de los pacientes tenian afeccion del tronco comun y el 87%, enfermedad de 3 vasos. En el 74% de los casos se realizo revascularizacion completa, con un numero medio de injertos de 2,97 (1-7). Se utilizo injerto de mamaria en el 100% de los casos. La mortalidad hospitalaria fue del 0,74%. Las complicaciones postoperatorias fueron pocas: el 0,98% preciso reintervencion por sangrado, en el 3,4% se elevo la troponina I de forma significativa, en el 6,4% se desarrollo insuficiencia renal y el 0,5% tuvo accidente vascular cerebral. Conclusiones La cirugia coronaria con MCEC permite realizar una revascularizacion completa en la mayoria de los pacientes, con buenos resultados de morbimortalidad.

A National Spanish Registry to compile all patients treated with high intensity focused ultrasound (HIFU) energy for atrial fibrillation (AF) was created to evaluate the safety and efficacy of AF surgical ablation.A national Spanish registry was created, and ten hospitals using HIFU to ablate AF joined it. A total of 412 patients undergoing cardiac surgery between 2006 and February 2013 were included. AF was divided between paroxysmal AF (33%) and persistent AF (67%) with a mean AF duration of 29.3±108.2 months. Mean left atrial diameter was 51.2±6.5 mm. Mean underlying heart disease were aortic valve disease (49.3%), ischemic disease (25.2%) and mitral disease (33.2%) Clinical follow-up of patients and a 6 months postoperative echocardiogram were performed in all patients.A pacemaker implantation was needed in 4.9% of patients with a perioperative stroke in 2.5%. Rhythm at discharge from hospital was sinus rhythm in 58%, AF in 35.9% and atrial flutter in 0.8% of patients. Sinus rhythm restoration at 6, 12, 24 and 36 months follow-up was achieved in 66.1%, 63.8%, 63.9% and 45.9% of patients respectively. Multivariate analysis showed paroxysmal AF and sinus rhythm restoration in the operating theatre as factors related to sinus rhythm long term restoration.The Spanish national registry showed an efficacy of AF ablation with the HIFU Epicor system of 66.1%, 63.8%, 63.9% and 45.9% at 6, 12, 24 and 36 months follow-up. There were no device-related complications.

OBJECTIVES - After a panel process, recommendations on the use of sutureless and rapid deployment valves in aortic valve replacement were given with special respect as an alternative to stented valves. METHODS - Thirty-one international experts in both sutureless, rapid deployment valves and stented bioprostheses constituted the panel. After a thorough literature review, evidence-based recommendations were rated in a three-step modified Delphi approach by the experts. RESULTS - Literature research could identify 67 clinical trials, 4 guidelines and 10 systematic reviews for detailed text analysis to obtain a total of 28 recommendations. After rating by the experts, 12 recommendations were identified and degree of consensus for each was determined. Proctoring and education are necessary for the introduction of sutureless valves on an institutional basis as well as for the individual training of surgeons. Sutureless and rapid deployment should be considered as the valve prosthesis of first choice for isolated procedures in patients with comorbidities, old age, delicate aortic wall conditions such as calcified root, porcelain aorta or prior implantation of aortic homograft and stentless valves as well as for concomitant procedures and small aortic roots to reduce cross-clamp time. Intraoperative transoesophageal echocardiography is highly recommended, and in case of right anterior thoracotomy, preoperative computer tomography is strongly recommended. Suitable annular sizes are 19–27 mm. There is a contraindication for bicuspid valves only for Type 0 and for annular abscess or destruction due to infective endocarditis. Careful but complete decalcification of the aortic root is recommended to avoid paravalvular leakage; extensive decalcification should be avoided not to create annular defects. Proximal anastomoses of concomitant coronary artery bypass grafting should be placed during a single aortic cross-clamp period or alternatively with careful side clamping. Available evidence suggests that the use of sutureless and rapid deployment valve is associated with (can translate into) reduced early complications such as prolonged ventilation, blood transfusion, atrial fibrillation, pleural effusions and renal replacement therapy, respectively, and may result in reduced intensive care unit and hospital stay in comparison with traditional valves. CONCLUSION - The international experts recommend various benefits of sutureless and rapid deployment technology, which may represent a helpful tool in aortic valve replacement for patients requiring a biological valve. However, further evidence will be needed to reaffirm the benefit of sutureless and rapid deployment valves.

Ectopic thyroid tissue is a rare congenital anomaly that results from multiple events during development. The ectopic thyroid may lie in several human organs including the tongue and mediastinum. It is rarely seen as an intracardiac mass. We report the case of a patient with an intracardiac mass diagnosed by echocardiography. The pathology of the mass was compatible with ectopic thyroid tissue with no signs of malignancy.

Mitral valve (MV) repair is the preferred surgical treatment for degenerative mitral regurgitation (MR). However, questions remain about the efficacy of MV repair when performed for MR caused by infective endocarditis (IE), particularly during its active phase. Although several observational studies have suggested the superiority of MV repair over replacement in patients undergoing surgery for IE, many centres are still opting for valve replacement because of its technical feasibility and reproducibility. In the following document we expose the experience of our hospital.We present a series of 4 patients who recently underwent surgery for IE during its active phase. Epidemiological and clinical characteristics are discussed.All patients underwent different MV repair techniques. No relapse or reinfection has been reported. All patients present MR grades 0 or iI/ivIV at follow up.Even during the active phase of IE, MV repair is a feasible technique with good postoperatory results.

Mitral valve repair is the procedure of choice to treat mitral valve regurgitation. However, the feasibility and durability of repair are influenced strongly by the valve pathology. The classic features of degenerative mitral valve disease include leaflet prolapse and annular dilatation. Risk of repair failure is increased by isolated anterior leaflet prolapse or bileaflet prolapse. A variety of techniques have been used to treat this pathology. The most popular include partial leaflet resection, chordal shortening, chordal transfer and chordal replacement. Use of artificial chordae with expanded polytetrafluoroethylene (e-PTFE) sutures is a well-known technique for mitral valve repair and long-term data validate this approach. The primary challenges with this technique are judging the proper length of the neochordae and tying the PTFE. Several different techniques have been proposed to solve these items but none of the established are very satisfactory. I describe a preliminary experience with a new device to determine the correct length of the neo-chordae and tying the knots without sliding in ten patients with severe mitral insufficiency referred for mitral valve repair.

We have read with great interest the study by Zhao et al. ([1][1]), which concluded that intraoperative coronary angiography should perhaps eventually become the standard of care for coronary artery bypass grafting (CABG) surgery. We ask, is it really necessary to perform it routinely? They showed

Background and Aim: Monitorization of complications in patients underlying cardiac surgery may be difficult because cardiopulmonary bypass (CPB) can lead to a systemic inflammatory response syndrome because of exposure of blood to nonphysiological surfaces. The purpose of the study was to establish the baseline levels of procalcitonin (PCT) after cardiac surgery in our population in order to analyze a possible induction of the inflammatory response that might interfere with the diagnosis of infection by PCT. Methods: Serum samples from patients undergoing coronary artery bypass grafting or valve replacement were collected at the time of admission to intensive care unit, after surgery as well as in the first and second postoperative days. Patients were followed for the development of postoperative complications. PCT levels were measured by immunoluminometric assay. Results: The mean PCT values were significantly higher in the first postoperative day in all the groups except the control group. No increased PCT levels were found related neither to duration of CPB, nor to time of aortic clamping. Only patients who presented complications had significantly increased PCT values immediately after surgery (p = 0.004), in the first postoperative day (p < 0.0001), and in the second postoperative day (p < 0.0001) with respect to those who recovered uneventfully. Conclusions: A slight and transient increase in PCT levels was observed in the first postoperative day after cardiac surgery. Significant elevation of PCT was only observed when complications were present.

Introduction and objectives. The increasing use of percutaneous interventions has resulted in a significant reduction in coronary artery bypass grafting. Today, patients referred for surgery are older, have more comorbidities, and have undergone previous percutaneous intervention, and their ventricular function is poorer. As a result, surgery has attempted to improve its results by adopting a number of different strategies. The aim of this study was to investigate and describe one cardiac surgery unit’s initial experience with coronary artery bypass grafting using mini-extracorporeal circulation (MECC), which had become its technique of choice. Methods. A retrospective analysis of 408 patients who underwent isolated coronary artery bypass grafting using MECC between January 2004 and April 2007 was carried out. Of the 408, 329 (80.6%) were men, their mean age was 63.5 years (28-83 years), 63% had hypertension, 49.3% had diabetes, 69% had hyperlipidemia, and 52% were smokers. Results. The surgical mortality rate predicted by the logistic EuroSCORE was 3.7% (range, 1-38). Overall, 34% of patients had left main coronary artery disease and 87% had 3-vessel disease. In 74%, complete revascularization was carried out using a mean of 2.97 (range, 1-7) grafts per patient. A mammary artery graft was used in all cases. The in-hospital mortality rate was 0.74%. There were few postoperative complications: 0.98% of patients required further surgery because of bleeding, 3.4% had a significantly elevated troponin-I level, 6.4% developed kidney failure, and 0.5% suffered a stroke. Conclusions. Coronary artery bypass grafting using MECC enabled complete revascularization to be performed in most patients, and morbidity and mortality rates were low.

A 2-year-old patient with severe mitral regurgitation associated with a mass originating from the anterior leaflet of the mitral valve is reported. Excision of the tumor and mitral valve repair was performed. Four years later the child remains asymptomatic with no recurrence of the tumor or regurgitation.

La valvula Mitroflow (Sorin Group) ha sido utilizada frecuentemente como sustituto protesico en la valvulopatia aortica. Sin embargo algunos estudios han favorecido la duda acerca del deterioro estructural acelerado de dicha protesis incluso en pacientes de edad avanzada. Material y metodos Analizamos de forma retrospectiva nuestra experiencia en los ultimos 10 anos. El seguimiento medio fue de 4,2 anos y completo en el 97%. En el periodo de enero de 2001 a 2010 se implantaron 181 protesis Mitroflow. Edad media al implante 76,0 ± 5,6 anos (83,4% mayores de 69 anos); 61,4% mujeres; 95% estenosis aortica (EAo) predominante; 53 pacientes (29,2%) con procedimientos asociados. La poblacion a estudio presentaba 90% hipertension arterial (HTA); 51% diabetes mellitus; 48% dislipemia, y 12,1% insuficiencia renal cronica (IRC). El 85% de las protesis fueron de tamano 19–21. Se analiza el deterioro estructural progresivo y necesidad de reintervencion mediante controles ecocardiograficos (anuales). Resultados Durante el periodo estudiado la supervivencia del grupo a los 3, 5 y 10 anos fue del 98, 92 y 82%, respectivamente. La presencia de mismatch teorico en el postoperatorio inmediato fue del 4,9% (EAo/SC Conclusiones – Los gradientes transprotesicos en pacientes con EOA/SC superior a 1 cm2/m2 fueron bajos y se mantuvieron estables en el seguimiento a largo plazo. – Durante el seguimiento tres pacientes se reintervinieron por deterioro estructural, a los 6, 5 y 3 anos.
