Percutaneous venopulmonary artery extracorporeal membrane oxygenation for right heart failure after left ventricular assist device insertion.

Objectives: Right ventricular failure after left ventricular assist device (LVAD) insertion is associated with significant mortality and morbidity. Mechanical support options include right ventricular assist devices, venoarterial extracorporeal membrane oxygenation (ECMO) and venopulmonary artery ECMO, the latter often involving central cannulation. We sought to evaluate the feasibility and early outcomes of a truly percutaneous venopulmonary artery (pVPA) ECMO strategy, with the potential advantage of bedside removal once weaned.

Low Tidal Volume Mechanical Ventilation Against No Ventilation During Cardiopulmonary Bypass in Heart Surgery (MECANO): A Randomized Controlled Trial.

Background: Postoperative pulmonary complications are common after cardiac surgery and have been related to lung collapse during cardiopulmonary bypass (CPB). No consensus exists regarding the effects of maintaining mechanical ventilation during CPB to decrease these complications.

Research Question: To determine whether maintaining low-tidal ventilation (3 mL/kg 5 times/min, with positive end expiratory pressure of 5 cm HO) during CPB (ventilation strategy) was superior to a resting-lung strategy with no ventilation (no ventilation strategy) regarding postoperative pulmonary complications, including mortality.

Giant coronary aneurysms, from diagnosis to treatment: A literature review.

Coronary aneurysms are classically defined as a segment of the artery in which dilation exceeds the diameter of an adjacent portion (considered as a reference point) by more than 1.5times. In rare instances, coronary artery aneurysms are large enough to be called giant coronary artery aneurysms, which have been reported as occurring with an incidence of 0.
