We describe a case of ruptured coronary artery aneurysm with a coronary artery to a pulmonary artery fistula. An 89-year-old woman with general fatigue and dyspnea was admitted. At the visit she went into shock and was restored by rehydration therapy. Enhanced computed tomography shows a coronary aneurysm (maximum diameter of 50 mm) at the left side of pulmonary artery and mild pericardial effusions. She was scheduled for an emergency operation due to the ruptured coronary artery aneurysm with a coronary artery to pulmonary artery fistula. We performed aneurysmectomy and ligation of the coronary artery to the pulmonary artery fistula under cardiopulmonary bypass. We also reviewed 23 cases of ruptured coronary artery aneurysm with coronary artery extending to a pulmonary artery fistula in Japan. The disease is a rare clinical state and regarded as an indication for emergency surgery.

A 64-year-old man originally underwent Bentall procedure for annulo-aortic ectasia for the first time at the age of 38 years. The surgery was to repair a pseudoaneurysm at the anastomotic site of the left coronary artery by direct closure 11 years after the first Bentall procedure. The anastomosis of the right coronary artery was normal at the time of the first reoperation. However, he had surgery to repair a pseudoaneurysm at the anastomotic site of the right coronary artery 26 years after the first operation ; this was accomplished using the button technique. However, seven months after the second reoperation, he again manifested a pseudoaneurysm at the anastomotic site of the left coronary artery and died of rupture of the pseudoaneurysm. We report the case of pseudoaneurysms at the right and left coronary artery anastomoses that occurred three times after the first Bentall procedure.

For A 38-year-old male diagnosed a congenital complete atrioventricular block in the neonatal period, epicardial lead and pacemaker was implanted through left thoracotomy. Although we tried to implant a pacemaker through the subclavian vein as an adult, it was unsuccessful because of obstruction of the bilateral subclavian vein. For this reason, we performed a pacemaker implantation with transatrial-endocardial lead through the right thoracotomy due to save the generator electric power. This is one of the useful techniques for cases with obstruction of the upper extremity vein.

A 27-year-old woman who suffered loss of consciousness twice after left femoral pain in the 25th week of gestation was referred to the obstetrics and gynecology department of our hospital. A structure with an attachment on the atrial wall was found in both atria on echocardiography, leading us to suspect impending paradoxical embolism (IPE). Judging from the shape of the thrombus in the atria, we thought that there was a high possibility of further embolism although rescue of the baby was feasible via cesarean section, so we decided to carry out emergency surgery. After delivering the infant by cesarean section, we used a heart-lung machine to incise the right atrium under hypothermia and remove the thrombus. As intraoperative esophageal echocardiography showed embolization in the right pulmonary artery, we cut the right pulmonary artery and removed the emboli. After surgery, a femoral vein thrombus was observed on echocardiography of the lower extremity vein, and we inserted an inferior vena cava filter. The patient was discharged on the 16th postoperative day. The situation whereby a thrombus is trapped in the foramen ovale without embolism of the arterial system is the rare pathological condition known as IPE. As no cases of surgical thrombectomy to treat IPE arising from complications of pregnancy have been reported thus far, the case described herein fittingly augments the literature.
