Aortopulmonary fistula with an arch aortic aneurysm is a rare disease that is difficult to diagnose and often presents with sudden, life-threatening heart failure. Here we report a case of aortopulmonary fistula for which we performed a thoracic endovascular aortic repair (TEVAR) with favorable results. A 79-year-old man presented with slurring of speech and body malaise at a neighborhood clinic. A distal arch aortic aneurysm was detected on chest computed tomography (CT) scans, and the patient was referred to our hospital for further management. We identified a saccular aneurysm and the dilated pulmonary artery, with maximum vessel diameters of 80 and 38 mm, respectively, on preoperative chest CT scans. He was diagnosed with an impending aortic rupture and a TEVAR was performed after preparing for a cervical ramification bypass. Intraoperatively, the aortopulmonary fistula had invaded the pulmonary artery, and the shunt created by the invasion was responsible for the sudden exacerbation of heart failure symptoms in the patient. The diameter of the saccular lump did not increase in the postoperative CT and follow-up visits were scheduled for subsequent monitoring. In the absence of significant complications and with improvement of heart failure symptoms, the patient was discharged from our hospital on the 37th postoperative day. He was later transferred to a neighborhood clinic for rehabilitation and subsequently discharged for further recuperation at home in the fifth postoperative month.

We report a case of ruptured chronic type B aortic dissecting aneurysm that was successfully treated with the Candy plug technique to exclude a false lumen. A 57-year-old man had undergone abdominal fenestration for complicated acute type B aortic dissection previously. He then underwent debranching TEVAR for an impending rupture because of a dilated thoracic aortic dissecting aneurysm in 2014. After one year, the aneurysm was ruptured because of continuous distal flow of the false lumen. We performed TEVAR using the Candy plug technique, and he was discharged on the 11th postoperative day. The false lumen diameter was reduced. TEVAR using the Candy plug technique for chronic type B aortic dissection was thought to be useful in high-risk patients, but we need more careful observation.

The efficacy of minimally invasive cardiac surgery (MICS) has often been reported. However, in Japan most of these procedures are supported with robotic systems, which are expensive. We report the technique of atrial septum defect (ASD) closure by MICS and a three-dimensional endoscope without the aid of a robotic system. From March 2012 to April 2015, we performed ASD closure using this method in 7 patients. The use of a three-dimensional endoscope enables cardiac surgery to be performed through smaller incisions (≤5 cm in width). We have adopted this method of ASD closure with the Maze procedure for patients complicated by atrial fibrillation. The operation time will decrease as we improve our surgical technique. Our current practice is to attempt ASD closure with totally endoscopic support.
