Echocardiographic factors associated with thromboembolic events in patients with cardiac amyloidosis without atrial fibrillation.

Aims: Cardiac amyloidosis (CA) is associated with various complications, and one of them are thromboembolic events (TEEs), which can significantly impact patients' quality of life. Predicting and managing the risk of these TEEs in patients without atrial fibrillation (AF) pose significant challenges, as many occur independently of AF presence. Several predictors, particularly echocardiographic ones, have been linked to an increased risk, but there is no consensus on stratification or preventive treatment.

Transcatheter mitral valve-in-valve implantation: reports of the first 50 cases from a Latin American Centre.

Objectives: Our goal was to analyse the initial results of the first 50 transapical transcatheter mitral valve-in-valve procedures performed in a single Latin American centre.

Methods: A prospective, single centre, database analysis was conducted to evaluate immediate, 30-day and 1-year postoperative results of 50 consecutive patients who had a transcatheter mitral valve-in-valve procedure from May 2015 to June 2018. All patients were operated on in a hybrid operating room and received a balloon-expandable valve via the transapical approach.
