- Abstract
Aim: Transcatheter aortic valve implantation (TAVI) became an attractive alternative to surgery for patients with severe aortic stenosis and high operative risk. The first multicenter randomized trial, conducted in such high risk cohort, showed 20% reduction in mortality in the group treated with TAVI compared to those treated with medical therapy (30.7% vs. 50.7% P=0.001) and a non-inferiority of TAVI compared to traditional valve surgical replacement for all-cause mortality at 1 year with, similar improvement of symptoms and physical performance. However, mortality rate of TAVI remains high (20-30% at one year). The purpose of this prospective single center study was to identify predictors of mortality and adverse events in patients undergoing TAVI in order to be able to select the ones who benefit most from the procedure., Methods: Between June 2009 and June of 2011, 118 patients with severe aortic stenosis treated with TAVI at IRCCS Humanitas Clinical Institute were included in a prospective registry. Pre procedural clinical and ecocardiographic evaluations, surgical risk estimation, and procedural complications, defined by VASC criteria, were recorded. Clinical and echocardiographic evaluations were performed at 1, 6 and 12 months after the implants. To investigate the predictors of mortality, clinical and anatomical characteristics of alive patients were compared with those of death ones at one month and one year follow-up., Results: The procedural success occurred in 92.4% of procedures; vascular complications (33%), bleeding complications (22%), postimplant paravalvolar grade ≥2 AR (20.4%) a new permanent pacemaker implant (19.7%), were the most common complications. Survival for the whole cohort at 30 days was 6.8%, survival at one year was 82.2%. In the logistic regression test, one month mortality was significantly adversely affected by the renal functional status (odd ratio 0.9356), by a previous history of coronary artery bypass grafting (odd ratio 39) and by the mean aortic annular diameter (odd ratio 0.512) (P=0.0005). One year mortality was influenced by high EuroSCORE (odd ratio 1.0399) and the presence of hemodynamically significant prosthetic regurgitation (odd ratio 3.8438)., Conclusion: TAVI procedure, in high risk patients with critical aortic stenosis, can be accomplished with low procedural mortality. The worst outcome affects particularly patients with renal insufficiency and previous coronary bypass. However, the long-term mortality remains high due to the poor baseline conditions, mainly related to co-morbidity and to the presence of residual post-procedural aortic insufficiency.

- Abstract
Primary percutaneous coronary intervention (PCI) is currently the preferred revascularization strategy in acute trasmural myocardial infarction (AMI). In this setting, about one half of patients will be diagnosed with concomitant multivessel (MV) coronary artery disease, associated with a multitude of negative prognostic factors but also still an independent predictor of adverse cardiac events and increased long-term mortality. Since additional "angiographic" lesions found at primary PCI are not directly responsile for the acute presentation, their treatment represents a difficult decision-making problem in cardiology. The article summarizes available clinical data on treatment in this setting and also review our current understanding of short-term progression of atherosclerosis after AMI.

- Abstract
Aim: To assess the prognostic value of admission plasma glucose (APG) respect to clinical variables and inflammatory markers in a selected population of non-diabetic patients with ST elevation myocardial infarction (STEMI) treated with primary angioplasty (primary coronary intervention, PCI)., Methods: A total of 188 consecutive non-diabetic STEMI patients undergoing primary PCI were divided into four quartiles based on APG (<117, 117-140, 141-170, >170 mg/dL). Combined end-point of major adverse cardiac events (MACE) was defined as death, acute heart failure, re-infarction, unstable angina or inducible ischemia., Results: Event-free survival from MACE was significantly (P<0.001) correlated with APG quartiles and decrease from the lowest to the highest: 6 months event-free survival was 89.3%, 77.4%, 59.1%, 42.5%. Patients with higher APG were characterized by a significantly higher Killip class (P<0.001), higher serum creatinine (P<0.05) on admission, and a lower rate of thrombolysis in myocardial infarction (TIMI) 3 flow after PCI (P<0.05). Multivariate analysis showed APG>170 mg/dL (hazard ratio [HR] 2.39, 95% confidence interval [CI] 1.24 to 4.65, P<0.01), admission high-sensitivity C-reactive protein level (HR 1.19, 95% CI 1.07 to 1.31, P<0.001), white blood cells count (HR 1.07, 95% CI 1.00 to 1.14, P<0.04) and heart rate (HR 1.02, 95% CI 1.00 to 1.04, P<0.02) to be independent predictors of MACE., Conclusion: Admission glycemia and inflammatory markers are independent predictors of MACE in the mid-term follow-up in non-diabetic STEMI treated with primary PCI. Further investigations are needed to study the pathogenesis of stress hyperglycaemia, interactions with mechanisms of inflammation and whether early and aggressive treatment with insulin may influence outcome of primary PCI.

- Abstract
Forty percent of patients treated with CABG need further revascularizations after 10 years mainly due to saphenous--more than arterial--graft disease. In this issue, the Authors make a critical review of current available literature on the treatment of saphenous and arterial graft disease, a subset of lesions for which a clear consensus for DES use is still lacking. The Authors examine both the positive and negative aspects of DES use in this setting. Percutaneous revascularizations with DES are feasible and safe. The antiproliferative properties of DES seem to be effective even in the treatment of bypass disease, in particular in saphenous grafts. The clinical efficacy of a treatment with DES is expressed mainly in the reduction of in-stent restenosis and, therefore, in the rates of target lesion revascularization (TLR). Moreover, the use of DES is not associated to higher rates of stent thrombosis and, in case of reintervention, recurrence rates seem to be limited. However, the benefit provided by DES in prevention of restenosis may be limited by the progression of the disease in other segments than those treated with stents. Percutaneous treatment of arterial bypass with DES is feasible and safe. Most of available data on DES are on anastomotic disease (data on bypass ostium and shaft are too scarce to draw any conclusion). In this case, where the use of stents is imperative, there is no evidence of advantages gained by the use of DES over BMS in terms of new revascularizations. Some unanswered questions on DES use in this setting still remain. For this reason new randomized trials are required to definitively give a reliable answer on DES efficacy in this subset of lesions.

- Abstract
Over the last years, endovascular intervention have become an important part of treatment in patients with congenital heart disease particularly for residual defects after surgery done in infancy. These transcatheter procedures can be described as dilatation of stenotic sites (angioplasty, endovascular stenting and valvuloplasty) or as a closure of anomalous openings (device closure defects and vascular embolisation). Balloon valvuloplasty, without or with stent, is the procedure of choice in adults with pulmonary valve stenosis, pulmonary arteries stenosis, bicuspid aortic valve stenosis without calcification, aortic re-coarctation. Treatment of native aortic coarctation is still under debate. Devices for closing atrial and ventricular septal defects or patent ductus arteriosus have been developed and are now widely used. Transcatheter, plug or coil occlusion is nowadays the goal treatment in a wide range of arterial and venous vascular connections. This review describes the current role of each major catheter-directed therapy in the treatment of congenital heart disease in adults.

- Abstract
Drug-eluting stents (DES) have significantly reduced the rates of in-stent restenosis (ISR). As previously observed with bare-metal stents (BMS), either patient's clinical characteristics and lesion morphology may influence the risk of recurrence even with DES. In this review we will focus on the most recent available data on clinical settings where DES efficacy on long-term outcomes are largely unknown. In particular, we report on very complex lesions (bifurcations, small vessels, chronic total occlusions, in-stent restenosis) myocardial infarction, multivessel disease, treatment of bypass graft and of unprotected left main disease. Several issues are still open on DES routinary use for these indications, mainly as far as stent thrombosis is concerned. Recent pathological studies show that DES are characterized by chronic inflammatory infiltrates and delayed endothelialization. Therefore, this effect could translate in a ''vulnerable period'' for thromboses longer than with BMS. Even though large meta-analysis have excluded higher rates of stent thrombosis with DES rather than with BMS, few cases of unusual very late stent thrombosis have been described, pointing out that this problem seems to be still unsolved. Although DES provide better angiographic outcomes in each clinical setting, further randomized studies are running to assess their safety and efficacy on currently off-label indications.

- Abstract
Intravascular ultrasounds (IVUS) allowed an innovative visualization of coronary artery disease. This technique developed first in the research field and, then, it was introduced in clinical practice as a supplement to coronary angiography in diagnosis of the severity of ischemic heart disease. The characteristic tomographic view of coronary plaque supplied by IVUS allowed to overcome the limitations of coronary angiography and to add important supplemental information in understanding the mechanism of action of several interventional devices. In this review we analyze current indications of use of IVUS in clinical practice and the future applications of IVUS-related techniques for the diagnosis of coronary artery disease.

- Abstract
Agenesis of the gallbladder and cystic duct is a rare congenital malformation. In 40-70% of cases this anomaly is associated with other gastrointestinal, skeletal, cardiovascular and genitourinary malformations. Lithiasis of the common bile duct is present in 25-50% of cases. In the majority of cases patients are asymptomatic or have symptoms compatible with a biliary disorder. A preoperative diagnosis is extremely difficult and the absence of the gallbladder is often an intraoperative finding. The authors report a case of isolated agenesis of the gallbladder. The relative embryology, development, diagnostic pitfalls, intraoperative behaviour and therapeutic strategies are discussed.

- Abstract
The surgical treatment of pancreatic carcinoma is palliative in 90% of cases. The authors report their experience with 25 patients with unresectable pancreatic exocrine cancer, 23 of whom underwent palliative surgery. Sixteen patients had a bilioenteric by-pass and in 7 cases a gastroenterostomy was associated. The postoperative mortality rate was 8.7% and morbidity 28.6%. Eight patients with bilioenteric bypass only survived and only two of these required gastroenterostomy later on because of neoplastic duodenal obstruction. The shorter hospital stay and the longer survival of patients treated by bilioenteric by-pass only suggest that prophylactic gastroenterostomy is unnecessary and should be associated in selected patients only.

- Abstract
Gastric lipoma responsible for repeated haemorrhage was observed in a 50-yr-old woman. The relevant literature is reviewed and reference is made to the rarity of this form. Its main clinical signs include a latent course, haemorrhage, and invagination of the tumour in the duodenum. It is stated that surgical management is necessary, owing to the high percentage of diagnostic uncertainty, and the serious haemorrhagic and occlusive complications mentioned.
