Background: Postoperative atrial fibrillation (POAF) is one of the most common complications of cardiac surgery and is associated with increased mortality and morbidity. Methods: We analyzed 830 patients without prior atrial fibrillation who underwent aortic valve replacement for aortic stenosis and/or aortic regurgitation. Results: The...

Background Redo aortic valve replacement procedures have been reduced by the growing practice of trans-catheter aortic valve-in-valve procedures. We analyzed our long-term results of redo aortic valve replacement procedures during a 10-year period in an effort to define subgroups in which trans-catheter aortic valve-in-valve procedures may be...

Functional mitral regurgitation remains one of the most complex and controversial aspect - for both clinicians and surgeons - in the management of mitral valve disease in the context of left ventricular dysfunction. Given the current absence of clear guidelines, as well as of results from randomized trials comparing the outcome of different...

Enlarged (> 50 mm) atria, longstanding (> 5 years) persistent atrial fibrillation (AF) and age > 70 years are considered predictive of recurrent AF following surgical ablation. The electrophysiological and clinical outcome after AF-ablation was evaluated in high-risk patients undergoing concomitant procedures.

Background: In the transcatheter aortic valve implantation (TAVI) years, very elderly patients with aortic stenosis (AS) are referred to surgery with reluctance despite excellent hospital outcomes. A poorly assessed outcome of discharged survivors might further overlook the actual efficacy of the surgical strategy in this cohort. We thus...

AimsIn patients with aortic stenosis (AS) functional mitral regurgitation (FMR) is frequent and is attributed to left ventricular (LV) remodelling and to aortic gradient. However, the association of these variables with mitral effective regurgitant orifice (ERO) is still unknown.Methods and resultsWe prospectively enrolled patients with aortic...

Background. OBSERVANT represents the first national observational study on the comparative effectiveness of transcatheter aortic valve implantation (TAVI) vs surgical aortic valve replacement (SAVR) at short, medium and long term, in a patient population with severe aortic stenosis (AS). The aim of this paper is to describe patient...

Background There is a paucity of prospective and controlled data on the comparative effectiveness of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) in a real-world setting. Objectives This analysis aims to describe 1-year clinical outcomes of a large series of propensity-matched patients who...

Objective: Transcatheter mitral valve-in-valve/valve-in-ring procedures (TM-VIVoR) are increasing. The authors aimed to identify independent predictors for hospital mortality in redo mitral valve surgery as possible future selection criteria for TM-VIVoR. Design: Retrospective multicenter registry. Setting: Tertiary university and community...

Background There is a paucity of prospective and controlled data on the comparative effectiveness of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) in a real-world setting. Objectives This analysis aims to describe 1-year clinical outcomes of a large series of propensity-matched patients who...

Objective Despite demonstration of the superior outcomes of transcatheter aortic valve implantation (TAVI) versus optimal medical therapy for severe left ventricular systolic dysfunction, studies comparing TAVI and surgical aortic valve replacement (AVR) in this high-risk group have been lacking. Methods We performed propensity matching for...

Risk stratification tools used in patients with severe aortic stenosis have been mostly derived from surgical series. Although specific predictors of early mortality with transcatheter aortic valve replacement (TAVR) have been identified, the prognostic impact of their combination is unexplored. We sought to develop a simple score, using...

A few studies recently reported controversial results with transfemoral transcatheter aortic valve replacement (TF-TAVR) versus transapical transcatheter aortic valve replacement (TA-TAVR), often without adequate adjusted analysis for baseline differences. Data on patients who underwent TF-TAVR and TA-TAVR from the Observational Study of...

OBJECTIVES: Although commonly reported as single-centre experiences, redo aortic valve replacement (RAVR) has overall acceptable results. Nevertheless, trans-catheter aortic valve replacement has recently questioned the efficacy of RAVR. METHODS: Early-to-mid-term results and determinants of mortality in 711 cases of RAVR from seven European...

Background - The proven efficacy of transcatheter aortic valve implantation (TAVI) in high-risk patients is leading to the expansion of its indications toward lower-risk patients. However, this shift is not supported by meaningful evidence of its benefit over surgical aortic valve replacement (SAVR). This analysis aims to describe outcomes of...
