Temporal Trends in Transcatheter Aortic Valve Implantation: 10-Year Analysis of the TAVIDOR Registry.

Background: Transcatheter aortic valve implantation (TAVI) has established itself as the preferential strategy to approach severe aortic stenosis. Information on procedural improvements and nationwide results obtained with the technique throughout the past decade are unknown.

Objectives: To assess the temporal variation of the demographic profile, procedural characteristics, and in-hospital outcomes of patients undergoing TAVI procedures at the Rede D'Or São Luiz.

Comparison of open commissurotomy and balloon valvuloplasty in mitral stenosis. A five-year follow-up.

Objective: To compare clinical and laboratory data in patients with mitral stenosis undergoing open commissurotomy or balloon valvuloplasty, who were followed up for 5 years.

Methods: Eighty-one patients were prospectively assessed prior to the procedure (PRE) and immediately after the procedure, in the immediate postoperative period (IPO), and followed up yearly for 5 years (PO12M, PO24M, PO36M, PO48M, and PO60M). They were randomized into the following 2 groups: GC (group undergoing open commissurotomy): 37 patients (32.
