Case ReportsAcquired coronary-to-bronchial artery fistula after two valve surgeries.
A 62-year-old woman with Takayasu arteritis and 2 prior aortic valve replacements, was admitted with unstable angina. Computed tomographic angiography showed a newly developed right coronary artery-to-right bronchial artery fistula. Because of dense aortic calcification, catheter embolization was undertaken, which was successful. We believe the acquired coronary artery fistula developed after her uneventful second aortic valve surgery, due to inevitable trauma to the mediastinum and ascending aorta, and partly due to her underlying Takayasu arteritis.

Observational StudyPatent ductus arteriosus in preterm infants: benefits of early surgical closure.
Patent ductus arteriosus in preterm neonates leads to significant morbidity. Surgery is indicated when pharmacological treatment fails or is contraindicated, but the optimal timing remains unclear. ⋯ Performing early ligation of symptomatic ductus arteriosus after unsuccessful pharmacological therapy in preterm neonates might lower complication rates and improve neurological outcome. Prospective randomized studies are needed to determine the optimal treatment.

Case ReportsGiant-cell aortitis: an unusual case of Bentall operation.
Noninfectious ascending aortitis is a very rare cause of ascending aortic aneurysm. We report a case of the truly fortuitous finding of this rare condition in a 67-year-old man operated on for an ascending aortic aneurysm associated with dystrophic aortic valve regurgitation. ⋯ A modified Bentall operation was performed. The pathological diagnosis was giant cell arteritis.

Case ReportsRight infarction response to coronary artery bypass and the Abiomed BVS 5000.
A 57-year-old man presented with acute right ventricular infarction. A percutaneous coronary intervention was undertaken, but he developed shock and required extracorporeal membrane oxygenator support. ⋯ Circulation gradually stabilized, and the device was removed after 5 days. There no sign of heart failure or infection at 9 months post-surgery.
