Comparative Study
Differential outcomes with early and late repeat transplantation in the era of the lung allocation score.
Rates of repeat lung transplantation have increased since implementation of the lung allocation score (LAS). The purpose of this study is to compare survival between repeat (ReTx) and primary (LTx) lung transplant recipients in the LAS era. ⋯ Late lung retransplantation appears to be as beneficial as primary transplantation in propensity-matched patients. However, survival is severely diminished in those retransplanted less than 90 days after primary transplantation. The utility of early retransplantation needs to be carefully weighed in light of risks.

An impending paradoxical embolism is a rare finding, with fewer than 200 cases being documented so far. A 68-year-old woman, who presented with 3 weeks of increasing exertional dyspnea and exercise intolerance, underwent transesophageal echocardiography with a finding of an embolus in both right and left atria. ⋯ The thrombus was removed intact, and the foramen ovale was closed. By our experience, an emergent cardiac surgery should always be considered as a treatment option for impending paradoxical embolism.

Surgical stabilization of the rib fractures has been successfully performed for the management of pain in multiple rib fractures, fixation of chronically painful nonunion, reduction of overriding ribs, and flail chest cases. Herein we report a patient who was treated with titanium rib clips after a motor vehicle accident leading to pulmonary parenchymal laceration and multiple painful rib fractures. ⋯ The patient underwent the second operation for restabilization of the broken ribs. We review the relevant literature, with particular emphasis on the management of this complication.

Uncommonly, adults with functionally univentricular hearts are becoming candidates for a Fontan procedure. The purpose of this study was to evaluate the course of patients undergoing the modified Fontan procedure with an extracardiac conduit in recent years. ⋯ The modified Fontan procedure with use of an extracardiac conduit can be performed in adults with encouraging early and midterm results. The majority of late survivors had improved quality of life. The incidence of late death, reoperation, arrhythmias, and thromboembolic events was low during follow-up.

Review Case Reports
Giant left ventricular thrombus formation associated with heparin-induced thrombocytopenia.
A 33-year-old man underwent urgent coronary artery de-obstruction for acute thrombotic occlusion of the left descending coronary artery. After 10 days of antiplatelet and heparin therapy, ventriculographic and echocardiographic control revealed a giant thrombus in the left ventricle, an ejection fraction of 40%, and severe mitral regurgitation. ⋯ After urgent mitral valve annuloplasty and left ventricular thrombectomy, the patient was discharged. In the literature, several cases of right atrial and ventricular thrombi have been described; however, to the best of our knowledge, this is the first report of giant left ventricular thrombus during heparin-induced thrombocytopenia.
