We report the case of severe hypoxemia attributable to right-to-left shunting through an atrial septal defect after right-sided pneumonectomy that developed in a 70-year-old man. Normal right atrial and pulmonary artery pressures were measured. Right-to-left shunting through a patent foramen ovale is known as a rare complication after pneumonectomy. Our patient, however, demonstrated a true atrial septal defect (septum secundum defect) upon open operative repair of the interatrial connection.

Coronary artery fistula (CAF) is a rare congenital anomaly that can be complicated by intracardiac shunts, endocarditis, myocardial infarction, or coronary aneurysms. Recent reports have emphasized the efficacy of percutaneous transcatheter techniques. The purpose of this article is to review a 28-year surgical experience with CAF as a standard for comparison and to discuss the emergence and efficacy of transcutaneous catheter coil embolization as an alternative form of therapy. ⋯ Early surgical management of CAF is a safe and effective treatment resulting in 100% survival and 100% closure rate. Transcatheter embolization is a reasonable alternative to standard surgical closure in only a very small, select group of patients. These surgical results should be considered the standard against which transcatheter techniques are compared.

Although it is frequently stated in the literature that thoracotomy is one of the most painful operative incisions, few data supporting this view are available. ⋯ The common belief that posterolateral thoracotomy is a very painful operative access is not true. Therefore it is not necessary to use special techniques for postthoracotomy pain relief in these patients. Patient-controlled analgesia is sufficient for pain relief after major thoracic or abdominal incisions.

Aortobronchial fistula is a rare complication of thoracic aortic operations that is fatal if not promptly diagnosed and repaired. The case of a 23-year-old woman who presented with an aortobronchial fistula after three previous left thoracotomies for thoracic aortic procedures is described.

Technique of right heart protection and deairing during heartmate vented electric LVAD implantation.
Continued experience with the TCI Heartmate Ventricular Assist System has led to improvements in our ability to avoid and manage right heart dysfunction during weaning from cardiopulmonary bypass. The advent of the electric device has intensified the need for these techniques because of its elevated minimal heart rate (50 beats/min) at start-up and the demands this places on the native right heart. We have developed and here describe a technique we have used successfully in our last 8 patients to assist in deairing and filling of the ventricular assist device, to partially support the right heart during the initial wean from cardiopulmonary bypass, and to avoid occasional overdistention of the right heart during early high left ventricular assist device flow.
