[Revascularization surgery through left off-pump thoracotomy is a viable alternative for coronary bypass re-operation].

Background: Despite substantial advances in treatment, coronary atherosclerosis is a progressive disease, for this reason a second surgery is frequent. The left anterior small thoracotomy operation on a beating heart is an alternative with less morbidity and mortality than the conventional surgery.

Cases Report: We report two cases of coronary surgery with limited access.

[Cardiovascular magnetic resonance evaluation of left-to-right shunts due to cardiac septal defects in patients with pulmonary arterial hypertension].

Introduction And Objectives: As cardiac septal defects are frequently associated with pulmonary arterial hypertension, hemodynamic assessment is essential before deciding on surgery. The aim of this study was to evaluate the use of cardiovascular magnetic resonance imaging for assessing cardiac shunts and for quantifying pulmonary artery systolic pressure in patients with cardiac septal defects.

Methods: This cross-sectional study involved patients with cardiac septal defects and clinically suspected severe pulmonary arterial hypertension who had an indication for cardiac catheterization and in whom magnetic resonance imaging was not contraindicated.
