Incidence of aortic valve reintervention in patients with aortic stenosis undergoing transcatheter aortic valve implantation versus surgical aortic valve replacement: a systematic review and updated meta-analysis of randomized studies.

Introduction: Transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) are established interventions for alleviating symptoms and enhancing survival in individuals with severe aortic stenosis (AS). However, the long-term outcomes and incidence of reintervention associated with TAVI and SAVR remain uncertain.

Methods: We conducted a systematic review and meta-analysis to compare the incidence of reintervention in TAVI versus SAVR.

Initial experience with minimally invasive cardiac operations.

Background: Minimally invasive cardiovascular operations have been proposed as an alternative method to correct several cardiac congenital and acquired heart diseases, with the aim to reduce morbidity and mortality.

Objectives: Describe the two years initial experience with minimally invasive operations, with emphasis on technical aspects and the learning curve.

Methods: Between July 2009 and March 2012, 95 patients were operated using minimally invasive operations.

Aortic valve replacement with the Cardioprotese Premium bovine pericardium bioprosthesis: four-year clinical results.

Objectives: This study reports the initial clinical and echocardiographic results of the Premium bioprosthetic aortic valve up to 4 years of follow-up.

Methods: Between October 2007 and July 2011, 121 consecutive patients were submitted for aortic valve replacement with the Premium bioprosthetic valve. The mean age was 68 ± 9 years and 64 patients were males.
