Multicenter Study Clinical Trial
Short-term hemodynamic performance of the mitral Carpentier-Edwards PERIMOUNT pericardial valve. Carpentier-Edwards PERIMOUNT Investigators.
Although long-term durability data exist, little data are available concerning the hemodynamic performance of the Carpentier-Edwards PERIMOUNT pericardial valve in the mitral position. ⋯ In this multicenter study, these mitral valves are associated with trace, although physiologically insignificant, central MR. Despite known echocardiographic limitations, the PERIMOUNT mitral valves exhibit similar hemodynamics to other prosthetic valves.

Randomized Controlled Trial Comparative Study Clinical Trial
Prospective randomized trial compares suction versus water seal for air leaks.
Surgeons treat air leaks differently. Our goal was to evaluate whether it is better to place chest tubes on suction or water seal for stopping air leaks after pulmonary surgery. A second goal was to evaluate a new classification system for air leaks that we developed. ⋯ Placing chest tubes on water seal seems superior to wall suction for stopping air leaks after pulmonary resection. However, water seal does not stop expiratory leaks that are 4/7 or greater. Pneumothorax may occur when chest tubes are placed on seal with leaks this large.

Comparative Study Clinical Trial
Clinical outcomes, angiographic patency, and resource utilization in 200 consecutive off-pump coronary bypass patients.
This retrospective study compared clinical outcomes and resource utilization in patients having off-pump coronary artery bypass grafting (OPCAB) versus conventional coronary artery bypass grafting (CABG). Angiographic patency was documented in the OPCAB group. ⋯ Off-pump coronary artery bypass grafting reduces hospital cost, postoperative length of stay, and morbidity compared with CABG on cardiopulmonary bypass. Off-pump coronary bypass grafting is safe, cost effective, and associated with excellent graft patency and clinical outcomes.

A saccular aneurysm in the right-sided aortic arch with aberrant left subclavian artery is an uncommon disease, and surgical treatment is complicated. Three patients with Edwards type III-B right aortic arch and enlargement of the Kommerell's diverticulum underwent operations. Right thoracotomy was the preferred approach for this lesion and partial cardiopulmonary bypass is a safe and simple procedure when the aortic arch has mild atherosclerosis.

Arrhythmias remain an unsolved problem in Ebstein's anomaly. The aim of this study was to investigate the evolution of arrhythmias after surgical repair. ⋯ Arrhythmia is not totally abolished after operation. However, patients with Ebstein's anomaly and arrhythmia show substantial improvement after conservative surgical intervention.
