Clinical impact of sex differences and procedural setting in transcatheter aortic valve implantation.

Background: Transcatheter aortic valve implantation (TAVI) is a well-established treatment for symptomatic patients with aortic stenosis. Yet, the impact of sex differences and public vs. private procedural setting on TAVI outcomes remain uncertain.

Spinal Anesthesia Increases the Frequency of Extubation in the Operating Room and Decreases the Time of Mechanical Ventilation after Cardiac Surgery.

Introduction: The delayed extubation of patients undergoing mechanical ventilation (MV) in the postoperative period of cardiac surgery (CS) is associated with mortality. The adoption of spinal anesthesia (SA) combined with general anesthesia in CS influences the orotracheal intubation time (OIT). This study aims to verify if the adoption of SA reduces the time of MV after CS, compared to general anesthesia (GA) alone.

Rescue of trapped Rotablator with knuckle technique for chronic total occlusion.

A 71-year-old man with Chagas disease and stable angina on minimum exertion underwent coronary computed tomography angiography and cine angiography that revealed heavily calcified multivessel disease involving the left main artery (LM). Due to the degree of calcification, it was decided to perform rotablation. The first-stage percutaneous coronary intervention (PCI) with rotablation was performed on the LM, left anterior descending artery and second diagonal branch without complications.

Percutaneous Transseptal Bioprosthetic Implantation in Failed Prosthetic Surgical Mitral Valve - Brazilian Multicenter Experience.

Background: Percutaneous intervention in patients with bioprosthetic mitral valve dysfunction is an alternative to conventional surgical treatment.

Objectives: To report the first Brazilian experience with transseptal transcatheter bioprosthetic mitral valve-in-valve implantation (transseptal-TMVIV).

Methods: Patients with surgical bioprosthetic dysfunction submitted to transseptal-TMVIV in 12 Brazilian hospitals were included.
