Porcelain aorta entails a high risk of cerebral as well as systemic embolism. We describe a case of aortic arch aneurysm with a circumferentially calcified aorta. The patient was a 61-year-old man on chronic hemodialysis who received aortic arch replacement. However, since chest CT scan revealed a totally calcified porcelain aorta and heavily calcified axillary artery, axillary artery cannulation was deemed to be contraindicated. On the other hand, possible complications caused by femoral artery cannulation are also well known, such as cerebral embolization. Therefore, transapical aortic cannula was used and aortic arch replacement was performed under deep hypothermic circulatory arrest. The patient was weaned from cardiopulmonary bypass without difficulty and had an uneventful recovery without any neurologic complications.

A 76-year-old woman with a sudden onset of chest and back pain was admitted to our hospital. Computed tomography (CT) showed a giant thoracoabdominal aortic aneurysm. Therefore, the patient underwent emergency operation. Under a left anterolateral thoracotomy and pararectal laparotomy with left heart bypass, we performed graft replacement of the thoracoabdominal aorta and reconstruction of the celiac artery, superior mesenteric artery and renal arteries. The left lung was tightly adhered to the aneurysm because of the contained rupture. Copious pulmonary bleeding and air leakage occurred due to thrombectomy of the aneurysm. During the operation, critical air leakage was repaired using the remaining aneurysmal wall. The postoperative course was uneventful. The patient was discharged 16 days after surgery. Copious air leakage due to lung injury was a potentially life-threating condition in the postoperative course of this case of thoracoabdominal aortic aneurysm. Surgical treatment of critical air leakage due to lung injury is very important in thoracic surgery.

Congenital quadricuspid aortic valve is a very rare malformation. We report two cases with severe aortic regurgitation due to isolated quadricuspid aortic valve. It consisted of three equal cusps and one smaller cusp, which was identified at the time of valve replacement surgery for severe aortic regurgitation.

We report a rare case of primary cardiac angiosarcoma in the right atrium. A 47-year-old man was admitted to our hospital with cardiac tamponade. Echocardiography and computed tomography revealed a tumor in the right atrial cavity. We performed tumor resection to confirm the histological diagnosis, to prevent tumor embolism, and to increase the possibility of improving the prognosis. The tumor was resected with the right atrial wall and right pericardium. The right atrium was then reconstructed with a bovine pericardial patch. The pathological diagnosis was angiosarcoma. The patient survived only about 6 months after surgical resection, but there was no local recurrence. This report presents a very rare case of cardiac angiosarcoma associated with cardiac tamponade.

In a 63-year-old male patient Jehovah's witness, IABP was introduced due to acute myocardial infarction and cardiogenic shock, and PCI (BMS) was carried out to CAG #7 100%. Stent placement was carried out and his hemodynamics stabilized. A left-to-right shunt was observed upon carrying out LVG, so the patient was referred to our hospital for surgery purposes due to a diagnosis of ventricular septal perforation (VSP). Upon transferring the patient to hospital, his PA pressure elevated to 53 mmHg although the blood pressure was maintained, and no findings of right heart failure were observed. His respiratory condition was stable. Emergency surgery was considered, but the patient was taking Clopidogrel following PCI, and so VSP repair (extended endocardial repair) was carried out following 4 days discontinuation of Clopidogrel. Preoperative anemia was not observed ; however, postoperative hemorrhagic anemia improved due to iron preparation administration, and the patient was discharged from hospital 22 days following surgery without blood transfusion.
