Although right ventricular assist device (RVAD) use has declined with the introduction of inhaled nitric oxide and phosphodiesterase inhibitors (type III), right ventricular dysfunction (RVD) is still a serious problem in patients receiving left ventricular assist devices (LVAD). ⋯ RVD in LVAD recipients remains poorly identified and is associated with a high transfusion rate and end organ failure that results in increased intensive care unit and hospital length of stay, and a high mortality rate. Preoperative identification of risk factors for RVD may select patients who would benefit from a biventricular assist device and prevent the subsequent end organ failure.

We report a case of an infant presenting with the rare association of tetralogy of Fallot, hypoplasia of the pulmonary arteries, and stenotic bicuspid aortic valve. Surgical correction, performed at 16 months of age, included aortic valvular commissurotomy, opening the right ventricular outflow tract (transannular patch), and ventricular septal defect closure. The postoperative course was favorable, and the child was discharged from the hospital. Three months after the procedure, the patient is in excellent condition, without cardiac medication.

Bronchopleural fistula (BPF) is a serious complication of lung resection. The management of persistent BPF is one of the most complex challenges encountered by thoracic surgeons. ⋯ Closure of small BPF by laser seems to be due to edema and to an inflammatory reaction of the bronchial mucosa surrounding the BPF. If the diagnosis of small proximal BPF is made in the absence of tumor or infection, Nd:YAG laser offers an option for endobronchial treatment of small (<2 mm) BPF. If this technique is successful, it avoids the morbidity associated with more invasive surgical procedures.

Case Reports
Successful repair of intraoperative aortic dissection detected by transesophageal echocardiography.
Aortic dissection is a rare but devastating complication of cardiac surgery. Early intraoperative diagnosis and management are essential for a favorable outcome. We describe the case of a 69-year-old man with worsening dyspnea who was admitted for mitral valve replacement having previously had a mitral valve repair. ⋯ This was characterized by acute onset hypovolemia. The transesophageal echocardiography showed the presence of features of acute aortic dissection involving only the descending aorta without identifying the entry point. The tear was successfully repaired by direct suture within the lumen.

The natural history and preferred approach to patients with intramural hematoma of the aorta remains controversial. We describe herein the management of the case of a 45-year-old woman with acute onset of chest pain, intramural hematoma of the arch and proximal descending aorta, and left pleural effusion. In this particular case, a nonsurgical approach led to complete recovery of the patient and documented resolution of the hematoma.
