Coronary arteriovenous fistula is a rare congenital heart disease. A 71-year-old woman suffered from heart failure due to massive coronary arteriovenous fistulae from the right coronary artery and left circumflex artery to the coronary sinus. Using the off-pump technique, we successfully performed Starfish-assisted obliteration of the fistulae. Intraoperative transesophageal echocardiography was used to confirm the complete elimination of the abnormal shunt flow.

We present the case of a 72-year-old woman who had an acute massive pulmonary embolism after abdominal surgery. The patient had undergone a right hemicolectomy and pancreaticoduodenectomy for locally invasive colonic adenocarcinoma. Six hours postoperatively, she required emergent intubation when she suddenly became cyanotic, severely hypotensive, and tachypneic, with an oxygen saturation of 50%. ⋯ Herein, we review the current literature on open surgical pulmonary embolectomy. This case supports the use of open pulmonary embolectomy for the treatment of hemodynamically unstable patients on the basis of clinical diagnosis. We discuss the role of emergent transesophageal echocardiography in the diagnosis and management of massive pulmonary embolism.

To investigate the management outcomes of patients who developed tracheal stenosis after tracheostomy or intubation, we reviewed the courses of 45 patients who had experienced tracheal stenosis at a single institution, over 19 years from February 1985 through January 2004. There were 38 tracheal and 7 infraglottic stenoses. Twenty-nine stenoses were associated with the stoma, 12 with the cuff, and 2 with the endotracheal tube resulting in infraglottic lesions; the remaining 2 were double stenoses. ⋯ A 2nd operation was required in 3 patients, and 1 of the 3 died of sepsis. Our management strategy of treating tracheal stenosis with resection and end-to-end anastomosis has been associated with good outcomes. Management of infraglottic stenosis is difficult, particularly when there is a large laryngeal defect or when there have been previous surgical attempts at the same site.

We report an unusual clinical presentation of an acute type A aortic dissection as a left hemothorax in a patient with a congenital pericardial defect. Although the pericardial defect was diagnosed preoperatively, we could not exclude the possibility of a ruptured descending aorta until we discovered the site of the rupture during operation. The presence of a pericardial defect would at first appear to be a fatal disadvantage in such a situation as this, due to massive bleeding into the pleural space; but we believe that in our patient spontaneous drainage of blood into the pleural cavity prevented severe cardiac tamponade. The only reason for his deteriorating hemodynamic status was hypovolemia, which was corrected with volume replacement.

Robotically assisted cardiac surgery has been presented as less invasive than conventional surgery, with shortened hospital stays and faster return to daily activities. We evaluated our experience with the da Vinci robot to determine whether we could in fact demonstrate those findings. All mitral and tricuspid valve repairs were performed by the same surgeon. ⋯ Two patients required late (> 3 month) mitral valve replacement for recurrent regurgitation. We have shown that a dedicated nonacademic institute can develop a robotic cardiac surgery program and perform mitral and tricuspid valve repairs successfully. There is a several-case learning curve, and patient selection is paramount.
