Minimally Invasive Cardiac Surgery for Left Ventricular Aneurysm with Large Mobile Thrombus Formation after Chemotherapy for Malignant Lymphoma / 日本心臓血管外科学会雑誌

We report a case of minimally invasive surgery (MICS) for left ventricular aneurysm with a large mobile thrombus, which appeared after chemotherapy for malignant lymphoma. A 42-year-old man with a postinfarction left ventricular aneurysm was admitted to our hospital to receive chemotherapy for malignant lymphoma. Eight days after the first administration of anticancer drugs, echocardiography revealed a large mobile thrombus in the left ventricular aneurysm that was absent on admission. The patient was referred to our department, and left ventricular endoplasty was performed through a small left thoracotomy. He recovered rapidly, and chemotherapy was resumed a month after surgery. This suggests MICS to be a valuable option for left ventricular aneurysm repair.

Minimally Invasive Cardiac Surgery for Partial Anomalous Pulmonary Venous Return to the High Portion of the Superior Vena Cava / 日本心臓血管外科学会雑誌

We report a case of minimally invasive cardiac surgery (MICS) for partial anomalous pulmonary venous return (PAPVR) to the high portion of the superior vena cava. A 34-year-old female was referred to our hospital for exertional chest oppression, and was diagnosed with PAPVR and a sinus venosus atrial septal defect. Two pulmonary veins were connected to the superior vena cava (SVC) : one to the SVC-atrial junction and the other to the high SVC adjacent to the azygos connection. We performed an intracardiac repair through a small right axillary incision. The postoperative course was uneventful. MICS may become a useful option for PAPVR repair.

A Case of Partial Arch and Descending Aortic Replacement for a Ruptured Type B Acute Aortic Dissection / 日本心臓血管外科学会雑誌

Ruptured type B acute aortic dissection (AAD) is a life-threatening condition, in which surgical treatment most often yields unsatisfactory results. We report a case of a ruptured type B AAD in a 67-year-old man detected on computed tomography that required a partial aortic arch replacement with reconstruction of the left subclavian artery with adjunct deep hypothermic circulatory arrest (DHCA). Although the patient had a postoperative stroke, he recovered markedly with rehabilitation. DHCA and open proximal anastomosis are useful for the surgical treatment of type B AAD, however, an elaborate strategy to prevent an intraoperative cerebral embolism is especially important.
