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.

Learning Curve for In-Hospital Mortality of Transcatheter Aortic Valve Replacement: Insights from the Brazilian National Registry.

Background: Robust data on the learning curve (LC) of transcatheter aortic valve replacement (TAVR) are lacking in developing countries.

Objective: To assess TAVR's LC in Brazil over time.

Methods: We analyzed data from the Brazilian TAVR registry from 2008 to 2023.

Complete Revascularization Versus Treatment of the Culprit Artery Only in ST Elevation Myocardial Infarction: A Multicenter Registry.

Background: Data on the management and prognosis of patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease are limited in Brazil, showing that the available revascularization strategies should be investigated.

Objective: To assess the outcomes of complete revascularization versus treatment of the culprit artery only in patients with STEMI and multivessel disease.

Methods: A prospective cohort study was conducted at two medical centers in southern Brazil with a 1-year follow-up after the index procedure.

Impact of Acute Kidney Injury on Short- and Long-term Outcomes After Transcatheter Aortic Valve Implantation.

Introduction And Objectives: Acute kidney injury (AKI) is frequently observed after transcatheter aortic valve implantation (TAVI) and is associated with higher mortality. However, the impact of AKI on long-term outcomes remains controversial. Therefore, we sought to evaluate the impact of AKI on short- and long-term outcomes following TAVI using the Valve Academic Research Consortium 2 criteria.

Surgical cutdown versus percutaneous access in transfemoral transcatheter aortic valve implantation: Insights from the Brazilian TAVI registry.

Objective: To compare the 1-year outcomes of complete percutaneous approach versus surgical vascular approach for transfemoral transcatheter aortic valve implantation (TAVI), among "real-world" patients from the multi-center Brazilian TAVI registry.

Background: Vascular access still remains a major challenge for TAVI via transfemoral approach. Vascular access through complete percutaneous approaches or through open surgical vascular techniques seems to be acutely similar.
