Transcatheter Treatment for Double-Chambered Right Ventricle in Patient Presenting Severe Chronic Heart Failure.

We report a case involving a 9-year-old girl with severe biventricular dysfunction due to anomalous right ventricle muscle bands. After a thorough discussion, she underwent a transcatheter stenting procedure for the double-chambered right ventricle. During her follow-up, she regained biventricular function, while remaining asymptomatic, resulting in complete recovery.

Assessment of TCF7L2 expression after bariatric surgery.

Objective: To assess the influence of bariatric surgery on transcription factor 7-like 2 (TCF7L2) expression and its association with body mass index (BMI) and Type 2 diabetes mellitus (T2DM).

Methods: Prospective study performed between 2016 and 2018, where 26 obese patients undergoing bariatric surgery were divided into two subgroups: diabetics and non-diabetics. The RNAs were extracted from peripheral blood samples that were obtained from each patient in two different moments: before surgery and after 12 months of follow-up.
