Randomized Controlled Trial Multicenter Study Clinical Trial
Trial of a novel synthetic sealant in preventing air leaks after lung resection.
Postoperative air leaks are a major cause of morbidity after lung resections. This study was designed to evaluate the efficacy and safety of a new synthetic, bioresorbable surgical sealant in preventing air leaks after pulmonary resection. ⋯ Air leaks after lung resection occur in most patients. The application of this novel surgical sealant appears to be effective and safe in preventing postoperative air leaks.

Review Case Reports
Dissection of atrial septum after mitral valve replacement.
We report a patient who presented with paraprosthetic leak complicated by dissection of the interatrial septum after mitral valve replacement. A review of the literature provides confirmation that only 3 cases have been previously reported of this potential, albeit extremely rare, complication of prosthetic mitral valve replacement. Prosthesis oversizing and improper mitral annular handling appeared to be the predisposing factors of this complication.

This is a 3-year follow-up of a gradually ballooning atrial septal aneurysm (ASA) which developed a spontaneous echo contrast and later a mobile thrombus in the aneurysm. This clearly demonstrates one of the pathogenetic mechanisms of systemic thromboembolism associated with ASA. In view of the risk of systemic thromboembolism or the need for lifelong anticoagulation treatment, the aneurysm was excised and an atrial septal patch was fashioned to close the resultant defect.

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.
