A 70-year-old woman with a history of bypass surgery for coarctation of the aorta (CoA) at approximately 10 years of age was referred to our hospital after a descending thoracic aortic aneurysm was discovered during a preoperative examination for uterine cancer. Contrast-enhanced CT revealed a 62×47 mm aneurysm in the descending thoracic aorta, connected to the bypass vessel, leading to the diagnosis of an anastomotic pseudoaneurysm following CoA surgery. Due to the large diameter of the aortic aneurysm and the high risk of rupture, we performed a left axillary artery to left femoral artery bypass in addition to thoracic endovascular aortic repair (TEVAR). Postoperative CT indicated no endoleak, and the patient was discharged after uterine cancer surgery with an uneventful recovery.

We present a successful case of a patient with multiple metal allergy—cobalt, nickel, chromium, and zinc—who had a past history of systemic metal dermatitis. He was a 58-year-old man who complained of exertional chest discomfort. After admission, he had a fever and his blood culture was positive with methicillin-sensitive Staphylococcus aureus. Three days later, multiple micro cerebral infraction was detected in magnetic resonance imaging. After an improvement of inflammatory reaction, he was transferred to our facility for cardiac examination. Moderate mitral regurgitation due to valve perforation and multiple coronary vessel stenosis were detected. Mitral valve replacement and coronary artery bypass grafting were planned to perform. We chose surgical materials based on a preoperative epicutaneous (patch) test and his clinical course was uneventful without any allergic reaction. Metal contact allergy is an important issue in cardiovascular surgery. A collaboration with dermatologists is essential for the preparation of surgical materials.

A 47-year-old female was admitted to our hospital for management of dyspnea. She had undergone surgery for an atrial septal defect (ASD) at the age of 17. Computed tomography revealed left isomerism, inferior vena cava interruption with azygos continuation and a residual ASD. Intra-operative findings showed that the residual ASD was positioned across the orifice of the hepatic vein. The previous suture line could be identified in the partially-closed atrial septum above the residual defect. Re-closure was performed without difficulties, and the patient's condition was good at discharge. Closure of ASD is a simple and basic procedure in cardiac surgery but care must be taken not to leave a shunt at the lower part of the defect, especially in cases with ASD defects in the lower margin.

A 67-year-old man with dilated cardiomyopathy was admitted to our hospital for treatment of cardiac failure. After using heparin because cerebral infarction developed during hospitalization, in acknowledgment of thrombocytopenia, we reach the diagnosis of HIT. We judged surgery to be necessary because heart failure had difficulty with catecholamine secession and the left ventricular dilation progressed rapidly, and performed left ventriculoplasty, mitral valve plasty. There were no complications such as the thrombosis during cardiopulmonary bypass, and the postoperative course was good without leading to re-thoracotomy due to bleeding. He passes without a heart failure symptom by the follow of one year 6 months after surgery at home.
