Background And Aims: Transcatheter aortic valve replacement (TAVR) determined a paradigm shift in the treatment of patients with severe symptomatic aortic stenosis but data on very long-term durability are lacking. We sought to evaluate the clinical and hemodynamic outcomes of the CoreValve porcine pericardial self-expanding bioprosthesis at 12-year follow-up.
Methods: 882 inoperable or high-risk patients were treated with the CoreValve bioprosthesis in 8 Italian high-volume centers between 2007 and 2011.
Background: Balloon post-dilation (BPD) is a widely adopted strategy to optimize acute results of TAVI, with a positive impact on both paravalvular leak and mean gradients. On the other hand, the inflation of the balloon inside prosthetic leaflets may damage them increasing the risk of structural valve deterioration (SVD). Furthermore, the impact of BPD on long-term clinical outcomes and valve hemodynamics is yet unknown.

Methods: Three hundred and seventy-seven patients from the Italian ClinicalService Project, who underwent TAVI between February 2011 and August 2020, were included. Tricuspid annular plane systolic excursion/pulmonary artery systolic pressure (TAPSE/PASP) ratio was retrospectively calculated as a surrogate of RV-PA coupling.
Aims: The aim of this study was to minimize the procedure, and reduce the length of hospital stay (LoS) is the future objective for transcatheter aortic valve replacement (TAVI).Aims of the study are to identify procedural and electrocardiographical predictors of fast-track discharge in patients who underwent TAVI.
Methods: Patients treated with TAVI included in the One Hospital ClinicalService project were categorized according to the LoS.
Background: We studied the incidence of primary graft dysfunction (PGD), its impact on in-hospital and follow-up outcomes and searched for independent risk factors.
Methods: During an 18-year period, 508 individuals underwent heart transplantation at our institution. Patients were diagnosed with none, mild, moderate or severe PGD according to ISHLT criteria.
Background: TAVR is a safe alternative to surgical aortic valve replacement (SAVR); however, sex-related differences are still debated. This research aimed to examine gender differences in a real-world transcatheter aortic valve replacement (TAVR) cohort.
Methods: All-comer aortic stenosis (AS) patients undergoing TAVR with a Medtronic valve across 19 Italian sites were prospectively included in the Italian Clinical Service Project (NCT01007474) between 2007 and 2019.
Right ventricular primary graft dysfunction after heart transplant is a serious life-threatening condition. The severe form, refractory to maximal medical therapy, has traditionally required temporary mechanical support through veno-arterial extracorporeal membrane oxygenation or central right ventricular support. The Protek Duo is a dual lumen cannula recently introduced in the market, which allows for the institution of a percutaneous right ventricular support.

Methods And Results: The analysis included 2,733 TAVI patients from the Italian Clinical Service Project. The population was stratified in four groups according to the presence of baseline severe CKD and postprocedural AKI.
Background: Bicuspid aortic valve (BAV) formation is genetically determined, with reduced penetrance and variable expressivity. NOTCH1 is a proven candidate gene and its mutations have been found in familial and sporadic cases of BAV.
Methods: 66 BAV patients from the GISSI VAR study were genotyped for the NOTCH1 gene.
Transfemoral transcatheter aortic valve implantation is an established therapy to treat elderly patients affected by severe aortic stenosis, who are considered to be at high or extreme risk for surgical aortic valve replacement. The transfemoral approach is contraindicated in patients with severe peripheral artery disease, small vessel size or severe tortuosity. In these patients, other vascular access routes such as transapical, subclavian or direct-aortic access may be considered.

The aim of this retrospective clinical and echocardiographic study was to evaluate the long-term survival results of conservative approach and the determinants of recurrent AR.
Methods: From 2000 to 2011, fifty patients (median: 63 years and interquartile range: 53-72) underwent an aortic valve-sparing procedure for acute aortic dissection, and discharged alive.
Transcatheter aortic valve implantation has been designed to treat older patients affected by severe aortic stenosis who are considered high-risk surgical candidates because of multiple comorbidities. The least invasive approach for transcatheter aortic valves implantation should be considered the transfemoral retrograde route, because it is minimally invasive and is feasible with local anesthesia and mild sedation. Despite significant technical improvements in recent years, the transfemoral approach is contraindicated in cases of severe peripheral artery disease.

Aim: We sought to determine wether pulse wave velocity (PWV), is related to AS severity and to the procedures response, both as surgical aortic-valve-replacement (AVR) and trascatheter-aortic-valve-implantation (TAVI).
Transcatheter aortic valves have been designed to treat high-risk surgical candidates affected by severe aortic stenosis, but little is known about the use of transcatheter valves in patients with severe pure aortic regurgitation. We describe the implantation of Medtronic CoreValve Evolut R (Medtronic, Minneapolis, MN) to treat an 82-year-old patient affected by severe pure aortic regurgitation who underwent prior mitral valve replacement with a biological valve protruding into the left ventricular outflow tract.

Involvement of aortic root and ascending aorta (aneurysm or, eventually, dissection) is frequent in patients with pathologic or normal functioning BAV. Unfortunately, there are no well-known correlations between valvular and vascular diseases.

Aim: To compair biological and clinical outcomes after off-pump coronary artery bypass grafting (OPCABG) and conventional on-pump coronary artery bypass grafting (CCABG) in the elderly with left ventricular (LV) dysfunction.
Material Of Study: We retrospectively reviewed 90 consecutive patients aged more than 75 years with preoperative left ventricular ejection fraction (LVEF) < 50% who underwent isolated coronary artery bypass grafting at our Institution between January 2000 and July 2009. According to operative technique, patients were categorized in to the OPCABG group (39 patients) or in to the CCABG group (51 patients).
Objectives: Despite substantial progress in surgical techniques and perioperative management, the treatment and long-term follow-up of type A acute aortic dissection (AAD) still remain a major challenge. The objective of this retrospective, multicentre study was to assess in a large series of patients the early and long-term results after surgery for type A AAD.
Methods: We analysed the preoperative, intraoperative and postoperative conditions of 1.

Redo cardiac surgery represents a clinical challenge due to a higher rate of perioperative morbidity and mortality. Mitral valve (MV) re operations can particularly be demanding in patients with patent coronary grafts, previous aortic valve replacement, calcified aorta or complications following a previous operation (abscesses, leaks or thrombosis). In this article we describe our technique to manage complex mitral reoperations using a minimally invasive approach, moderate hypothermia and avoiding aortic cross-clamping.

We analysed our experience with three different cardioplegic solutions in adult HT performed during past 5 years, in terms of non-immunological intraoperative biventricular graft failure (BVF) and in-hospital mortality.
Methods: A total of 133 patients underwent HT at our hospital from January 2006 to December 2010.
Heart valve hemangioma is a rare finding. Here, we report a case of a hemangioma completely replacing the septal leaflet of the tricuspid valve. Preoperative imaging studies and operative anatomy are described.

Several authors reported that chronic dialytic patients have a high operative risk when submitted to coronary artery bypass grafting (CABG) on cardiopulmonary bypass (CPB) whereas little information exists about off-pump myocardial revascularization in these patients.
Material And Methods: Between January 2000 and December 2008, 17 consecutive patients (12 men, mean age of 62.
