Left atrial intramural hematoma (LAIH) is an uncommon entity for which a timely diagnosis is critical for decision making. Cardiac surgical or catheter-based procedures are potential causing factors. Though cardiac computerized tomography and magnetic resonance are highly accurate diagnostic modalities, their role is limited by the lack of widespread availability. The present clinical case illustrates the diagnostic features of LAIH that can be obtained using echocardiography at the bedside in critically ill patients. We report a case of LAIH, that followed a catheter ablation procedure and was complicated by cardiac and cerebral ischemia. Cardiac surgical management was required.

AIMS: To compare early and late mortality of acute isolated tricuspid valve infective endocarditis (TVIE) treated with valve repair or replacement.METHODS: Patients who were surgically treated for TVIE from 1983 to 2018 were retrieved from the Italian Registry for Surgical Treatment of Valve and Prosthesis Infective Endocarditis. All the patients were followed up by means of phone interview or calling patient referral physicians or cardiologists. Kaplan-Meier method was used to assess late survival and survival free from TVIE recurrence with log-rank test for univariate comparison. The primary end points were early mortality (30 days after surgery) and long-term survival free from TVIE recurrence.RESULTS: A total of 4084 patients were included in the registry. Among them, 149 patients were included in the study. Overall, 77 (51.7%) underwent TV repair and 72 (48.3%) TV replacement. Early mortality was 9% (13 patients). Expected early mortality according to EndoSCORE was 12%. The TV repair showed lower mortality and major complication rate (7% and 16%), compared with TV replacement (11% and 25%), but statistical significance was not reached. Median follow-up was 19.1 years (14.3-23.8). Late deaths were 30 and IE recurrences were 5. No difference in cardiac survival free from IE was found between the two groups after 20 years (80 ± 6% Repair Group vs 59 ± 13% Replacement Group, P = 0.3).CONCLUSIONS: Overall results indicate that once surgically addressed, TVIE has a low recurrence rate and excellent survival, apparently regardless of the type of surgery used to treat it.

Objective To analyze Italian Cardiac Surgery experience during the pandemic of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) identifying risk factors for overall mortality according to coronavirus disease 2019 (COVID‐19) status. Methods From February 20 to May 31, 2020, 1354 consecutive adult patients underwent cardiac surgery at 22 Italian Centers; 589 (43.5%), patients came from the red zone. Based on COVID‐19 status, 1306 (96.5%) were negative to SARS‐CoV‐2 (COVID‐N), and 48 (3.5%) were positive to SARS‐CoV‐2 (COVID‐P); among the COVID‐P 11 (22.9%) and 37 (77.1%) become positive, before and after surgery, respectively. Surgical procedures were as follows: 396 (29.2%) isolated coronary artery bypass grafting (CABG), 714 (52.7%) isolated non‐CABG procedures, 207 (15.3%) two associate procedures, and three or more procedures in 37 (2.7%). Heart failure was significantly predominant in group COVID‐N (10.4% vs. 2.5%, p = .01). Results Overall in‐hospital mortality was 1.6% (22 cases), being significantly higher in COVID‐P group (10 cases, 20.8% vs. 12, 0.9%, p

Background: Use of a minimally invasive approach for isolated aortic valve surgery is increasing. However, management of the root and/or ascending aorta through a mini-invasive incision is not so frequent. The aim of this study is to report our initial experience with surgery of the ascending aorta through a ministernotomy approach. Methods: We retrospectively analyzed 102 patients treated for ascending aorta disease through a ministernotomy. Several types of surgeries were performed, including isolated or combined surgical procedures. Pre-operative and operative parameters and in-hospital clinical outcomes were retrospectively analyzed. Results: Patient mean age was 63.9 ± 13.6 years (range 29–85). There were 33 (32.4%) female and 69 (67.6%) male patients. Preoperative logistic EuroSCORE I was 7.4% ± 2.1%. Mean cardiopulmonary bypass and aortic cross-clamp time were 123.7 ± 36.9 and 100.8 ± 27.5 min, respectively. In-hospital mortality was 0%. Conclusions: Our experience shows that surgery of the ascending aorta with or without combined procedures can be safely performed through an upper ministernotomy, without compromising surgical results. Although our series is not large, we believe that the experience gained on the isolated aortic valve through a ministernotomy can be safely reproduced in ascending aorta surgery as a routine practice.

Objective An increasing number of elderly patients are referred for pulmonary endarterectomy. The distinction between operable and inoperable lesions has been challenged over time. Hence, we developed alternative cardiopulmonary bypass management and cerebral protection strategies to obtain satisfactory surgical results according to the changing patient features. Methods From April 1994 to March 2011, 347 pulmonary endarterectomies were performed at our center. We began with the technique championed by the San Diego Group, adopting a single period of deep hypothermic circulatory arrest for each side (group A). Since 2003, we began to perform short periods of intermittent deep hypothermic circulatory arrest followed by periods of reperfusion (group B). We then adopted moderate, instead of deep, hypothermia (group C). Finally, we modified our technique further performing shorter (5–7-minute) periods of circulatory arrest (group D). Results The hemodynamic results after surgery were excellent in all 4 groups. The patients' age increased significantly. A trend toward an increase in the number of Jamieson type 3 lesions was observed. Associated with our protocol changes, we observed better postoperative respiratory function, a reduction in the length of mechanical ventilation and postoperative infections, and a remarkable improvement in uneventful postoperative courses. Despite the increased total circulatory arrest time, a trend toward a reduction in the incidence of transient neurologic events was observed, and operative mortality was not affected. Conclusions In our experience, our alternative strategy resulted in a better combination of surgical accuracy and cerebral protection and improved outcomes.

OBJECTIVES Antiphospholipid (a-PL) antibodies, especially IgG isotype, have been associated with a variety of neurological manifestations related to thrombotic mechanism and reactivity against nervous tissues. Furthermore, high titre of a-PL antibodies has been also correlated to chronic thromboembolic pulmonary hypertension (CTEPH) and, therefore, is frequently reported in patients undergoing pulmonary endarterectomy (PEA). The impact of a-PL antibodies in postoperative outcome following PEA, however, has not been clearly evaluated yet. In this paper, we investigated the impact of a high a-PL IgG titre (HAPT) on postoperative outcome following PEA. METHODS From April 1994 to October 2008, out of 204 patients undergoing PEA at our centre, 184 were prospectively screened for a-PL antibodies. According to the preoperative IgG titre, patients were divided into two groups: Group A (high a-PL antibodies titre - HAPT) with a-PL IgG titre >10 U/ml and Group B (low a-PL antibodies titre - LAPT) with a-PL IgG titre

The study investigates Quality of Life (QOL) and correlation with functional status of patients affected by Chronic Thromboembolic Pulmonary Hypertension who undergo Pulmonary Endoarterectomy.We investigated with an observational design (before surgery, three and twelve months afterwards) the hemodynamic data (NYHA class, mean pulmonary arterial pressure, cardiac output and pulmonary vascular resistance), the functional status (using the 6-Minute Walk Test) and the QOL, using three questionnaires: Medical Outcome Study Short Form-36 (SF-36), Minnesota Living with Heart Failure Questionnaire (MLHFQ), Saint George Respiratory Questionnaire (SGRQ). We report the results of forty-nine patients.After surgery there was an improvement on functional and hemodynamic parameters and on QOL. The physical domain (PCS) of SF-36 was weakly but significantly associated with all functional parameters. There was no association between functional parameters and mental domain (MCS) of SF-36 or SGRQ. The improvement in 6-Minute Walk Distance was associated with an increase in MLHFQ.Both QOL and submaximal exercise tolerance improve after surgery. However only the physical domains of SF-36 appear to be significantly associated to the functional data.

Objective Chronic immunosuppressive therapy following solid organ transplantation has been correlated with an increased risk of posttransplantation neoplastic disease (PTND). In this study we evaluated PTND incidence and outcome at our institution over a 17-year period among patients receiving lung transplantation. Materials and Methods Between February 1992 and December 2008, we performed 290 lung transplantations in 280 patients, including 139 single (48% with 5 retransplantations), and 151 double lung transplantations (52% with 5 retransplantations). Among the 280 patients, 2 had undergone previous double lung transplantation in other hospitals. Follow-up of transplant recipients was performed up to December 2009. Results Forty-two patients died in the hospital, producing a cumulative early (30-day) mortality rate of 15%. Among the 238 patients discharged from the hospital who entered our follow-up program, 36 (15%) experienced PTND. The mean time between transplantation and diagnosis was 47 ± 42 months, and patients' mean age at time of diagnosis was 55 ± 14 years. Overall freedom from PTND was 97%, 84%, and 73% at 1, 5, and 10 years, respectively. PTND was considered to be the direct cause of death in 11 patients (30%). Overall survival of patients with PTND at five years (45%) did not differ from the remainder of the transplanted population (46%). However, PTND became a relevant cause of death in the long-term (> 5 years) follow-up. Conclusion Our experience confirms that PTND was frequently diagnosed following lung transplantation. Even if PTND did not seem to significantly affect the survival of patients undergoing lung transplantation, it may become a significant cause of death among those surviving beyond 5 years.

The objective of this retrospective study is to analyze functional recovery and response to rehabilitation treatment during the immediate postoperative phase of aortocoronary bypass (ACB) surgery.We studied 319 patients, who had undergone ACB surgery and who needed post-acute rehabilitation.All patients presented post-operative respiratory dysfunction, 300 cases presented inability in position changes and needed neuromotor exercises in addition to chest physiotherapy. Rehabilitation treatment began at a mean number of 1.79 +/-1.37 days after surgery and continued for 5.78 +/- 3.59 days. At the discharge, at mean 5.47 +/- 2.25 days after surgery, most of patients (65.61%) walked independently.Our study described a protocol of early rehabilitative treatment that appeared to be suitable in promoting patients'functional recovery after aortocoronary bypass surgery.

There are few follow-up studies on long-term cardiopulmonary function after pulmonary endarterectomy (PEA), the operation of choice for chronic thromboembolic pulmonary hypertension (CTEPH).To prospectively evaluate long-term outcome of patients with CTEPH treated with PEA.Between 1994 and 2006, 157 patients (mean age 55 yr) were treated with PEA at Pavia University Hospital. The patients were evaluated before PEA and at 3 months (n = 132), 1 year (n = 110), 2 years (n = 86), 3 years (n = 69), and 4 years (n = 49) afterward by NYHA class, right heart hemodynamic, spirometry, carbon monoxide transfer factor (Tl(CO)), arterial blood gas, and treadmill incremental exercise test.Cumulative survival was 84%. Within 3 months, 18 patients died in-hospital and 2 had lung transplantation; during long-term follow-up, 6 died, 1 had lung transplantation, and 3 had a second PEA (2.5 events per 100 person-years). NYHA class III-IV was the most important predictor of late death, lung transplant, or PEA redo (hazard ratio, 3.94). Extraordinary improvement in NYHA class, hemodynamic, and Pa(O(2)) were achieved in the first 3 months (P0.001) and persisted during follow-up; exercise tolerance progressively increased over time (P0.001). At 4 years, although 74% of the patients were in NYHA class I and none was in class IV, 24% had pulmonary vascular resistance greater than 500 dyne.s/cm(5) or Pa(O(2)) less than 60 mm Hg; they were significantly older and were more frequently in NYHA class III-IV 3 months after surgery than the others.After PEA, long-term survival and cardiopulmonary function recovery is excellent in most patients.

Acute pulmonary embolism is the third most common cardiovascular disease in Italy with approximately 65 000 new cases a year. Appropriate medical therapy does not necessarily prevent evolution of acute pulmonary embolism into chronic thromboembolic pulmonary hypertension (CTEPH), which occurs in 0.1-4.0% of cases. In our country, there are approximately up to 2600 new CTEPH patients a year. CTEPH is a progressive and potentially lethal disease. Medical therapy is palliative and only surgery can modify its natural history. Pulmonary endarterectomy (PEA) is the treatment of choice and lung transplantation should be considered only when PEA is contraindicated. Currently, nearly 4000 PEAs have been performed worldwide. Approximately ten centers are able to carry out this intervention with excellent and permanent results. Solid experience and close multidisciplinary collaboration allow appropriate patient selection, rigorous surgical technique, and adequate postoperative management. All these aspects represent the key to the success in the treatment of CTEPH. After PEA, quality and expected length of life are similar to the age-matched general population and the only therapy required is oral anticoagulation.
