Transcatheter aortic valve replacement (TAVR) in pure aortic regurgitation (AR) is challenging, because of the subsequent difficulty in anchoring the transcatheter valve in a noncalcified device landing zone (DLZ). Prestenting can help to prepare a stable DLZ for TAVR in pure AR and prevent valve migration. Here we report the first-in-human implantation of an uncovered stent into a noncalcified aortic valve as a prestenting strategy to prepare an easy DLZ for TAVR in pure AR. We consider this technique a useful novel tool to improve device success, at least as long as specific TAVR devices for pure AR are lacking.

: New-onset postoperative atrial fibrillation (POAF) is the most common complication after cardiac surgery, occurring approximately in one-third of the patients. This study considered all-comer patients who underwent cardiac surgery to build a predictive model for POAF. : A total of 3467 (Center 1) consecutive patients were used as a derivation cohort to build the model.

Paravalvular leak (PVL) was initially recognized as one of the most common complications after transcatheter aortic valve implantation (TAVI) and has been linked to adverse clinical outcomes, including mortality. This study aims to assess the long-term clinical effects of PVL in patients undergoing TAVI with the latest generation of transcatheter aortic valves, as part of the national observational prospective multicenter study OBSERVANT II. OBSERVANT II included all consecutive patients with severe aortic stenosis who underwent TAVI across 28 Italian centers from December 2016 to September 2018.

Previous studies evaluated the prognostic role of hematological parameters in predicting outcome in patients with infective endocarditis (IE). However, only a few studies evaluated the role of hematological parameters in patients undergoing surgery for IE. The aim of this study was to review our 20-year experience with the treatment of native (NVE) and prosthetic (PVE) valve endocarditis and to evaluate the role of neutrophil-to-lymphocyte ratio (NLR), neutrophil-to-platelet ratio (NPR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), neutrophil-to monocyte ratio (NMR), and systemic inflammatory index (SII) on early and long-term outcomes of patients undergoing surgery for NVE and PVE.

Stuck prosthetic valves, often resulting from pannus formation or thrombus accumulation, represent a critical complication in prosthetic valve management, carrying significant risks for morbidity and mortality. This study aims to identify factors associated with stuck valve development and assess the effectiveness of interventions in restoring normal valve function. A total of 27 patients with stuck valves were analyzed, including mitral, aortic, and tricuspid valve cases.

Myocardial work (MW) is a new echocardiographic parameter used in the assessment of cardiac energy expenditure. The aim of the current study was to evaluate changes in left ventricular MW parameters in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI). One hundred and thirty five consecutive patients who underwent TAVI at one center were evaluated before and after the procedure using transthoracic echocardiography (TTE) to assess the following MW indices: global constructive work (GCW), global wasted work (GWW), global work index (GWI) and global work efficiency (GWE).
