Mitral valve repair, how to make volume not matter; techniques, tendencies, and outcomes, a single center experience.

Background: Recent evidence has showed us that quality of mitral valve repair is strongly related to volume. However, this study shows how low-volume centers can achieve results in mitral valve repair surgery comparable to those reported by referral centers. It compares outcomes of mitral valve repair using resection versus noresection techniques, tendencies, and rates of repair.

Wide Dissection and Intercostal Vessel Division Allows for Repair of Hypoplastic Aortic Arch Through Thoracotomy.

Background: The approach to coarctation of the aorta with hypoplastic aortic arch is controversial. We evaluated the outcomes in patients with coarctation of the aorta with or without hypoplastic aortic arch operated through a posterior left lateral thoracotomy.

Methods: A retrospective cohort of patients with aortic coarctation, who underwent repair between January 2009 and October 2017, was analyzed.

Identification of clinically relevant phenotypes in patients with Ebstein anomaly.

Background: Ebstein anomaly (EA) is a heterogeneous congenital heart defect (CHD), frequently accompanied by diverse cardiac and extracardiac comorbidities, resulting in a wide range of clinical outcomes.

Hypothesis: Phenotypic characterization of EA patients has the potential to identify variables that influence prognosis and subgroups with distinct contributing factors.

Methods: A comprehensive cross-sectional phenotypic characterization of 147 EA patients from one of the main referral institutions for CHD in Colombia was carried out.
