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.

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.

Outcomes of the Fontan operation in children initially palliated with the modified Norwood procedure are incompletely defined. ⋯ In relatively high-risk patients, midterm results of the Fontan operation for children initially palliated with the Norwood procedure were good. Combined interventional-surgical treatment algorithms can lead to improved outcomes.

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.
