Cardiac metastasis from cervical cancer is rare. We herein present a case involving a 54-year-old woman with cervical cancer who was undergoing radiotherapy for left supraclavicular lymph node metastasis. The patient was admitted to the hospital because of shortness of breath. Transthoracic echocardiography showed a large mass in the right ventricle. To rescue the patient from circulatory collapse, we surgically resected the intracardiac mass via a right ventricular incision parallel to the posterior descending artery and left anterior descending artery. This approach prevented right ventricular outflow tract obstruction and perioperative pulmonary embolization, which could have led to death. The intracardiac mass was diagnosed as squamous cell carcinoma. After hospital discharge, the patient underwent chemotherapy. An echocardiography performed 3 months postoperatively showed recurrence of the cardiac metastasis, and the patient died 5 months later. Cardiac metastasis in the right ventricle can present as pulmonary embolization. Although rare, most cases of metastasis from cervical carcinoma to the heart have an extremely poor prognosis.

We herein report a case of cardiac tumor resection through a right mini-thoracotomy. A 48-year-old man exhibited no symptoms. A mass was detected incidentally in the right atrium on computed tomography. We performed resection under cardiopulmonary bypass through a right mini-thoracotomy. Histopathological examination confirmed that this tumor was a lipoma. The patient's postoperative recovery was uneventful. He was discharged on postoperative day 6. As cardiac tumor resection through right mini-thoracotomy is minimally invasive, this approach may be useful for surgery in cases of benign cardiac tumors.

We report a case of redo mitral valve replacement via right thoracotomy for ischemic mitral regurgitation after coronary artery bypass grafting. An 81-year-old woman with a history of multiple coronary artery bypass grafting was admitted to our institute for treatment of severe ischemic mitral valve regurgitation. She had a history of repeated hospitalization for heart failure and complained of worsening dyspnea. Coronary angiography showed patent coronary grafts. Echocardiography revealed severe mitral regurgitation with leaflet tethering and posteroinferior wall asynergy. The patient underwent mitral valve replacement (Mosaic Bioprosthesis 27 mm) via right thoracotomy approach with ventricular fibrillation under moderate hypothermia. The ventricular fibrillation time was 57 min, and the cardiopulmonary bypass time was 126 min. The patient's postoperative recovery was uneventful. She was discharged on postoperative day 19. Right thoracotomy approach provided excellent exposure of the mitral valve and minimized the risk of repeat sternotomy, including injury of previous bypass grafts, injury of right ventricle and significant hemorrhage.

The splenic artery is a common site of intraabdominal aneurysms. Very few patients present with symptoms before a splenic artery aneurysm ruptures. However, the symptoms vary depending on the type of aneurysm. Some patients present with hemodynamic shock, while others develop mild lumbago, anemia, or syncope. Thus, it is sometimes difficult to diagnose and treat ruptured splenic aneurysms. We report a rare case of rupture of a small splenic artery aneurysm, which remained undetected for 3 months after the appearance of the first symptoms, i.e., anemia and melena, despite conducting different examinations at our hospital. A 74-year-old man who underwent a graft replacement of an abdominal aortic aneurysm in 2006 complained of melena in May 2011. He was severely anemic, but presented with no other symptoms. A 16-mm-diameter splenic aneurysm was detected during a previous operation. The splenic artery aneurysm, as seen on computer tomography (CT) scans, showed no significant change in diameter for 5 years. The patient underwent upper and lower gastrointestinal endoscopy, capsule endoscopy, and enhanced CT at the Department of Gastroenterology to determine the site of the bleeding. However, the source of the bleeding was unclear. Finally, a diagnosis by elimination was made and the cause of the melena was identified as a ruptured splenic aneurysm. The splenic artery aneurysm was treated with coil embolization, and the patient's anemia was cured. The splenic artery aneurysm ruptured and bled into the pancreatic duct. The findings of this case suggest that a small splenic artery aneurysm rupture might not cause major symptoms like hemodynamic shock or large hematomas that can be identified on CT scans, but they may bleed into visceral organs. Therefore, interventions for the treatment of a non-symptomatic abdominal visceral artery aneurysm should be carried out promptly.

Combined surgery for left Subclavian artery revascularization and CABG was performed in a 74-year-old man with diabetes mellitus. The preoperative coronary angiogram showed critical stenoses in all three major branches, and arteriography revealed obstruction at the left proximal subclavian artery. Severe atherosclerotic calcification was acknowledged circumferentially in the ascending aorta and in the aortic arch. For this patient axillo-axillary crossover bypass grafting was performed first using and expanded PTFE graft, followed subsequently by off-pump CABG using all <i>in situ</i> grafts (right internal thoracic artery-left anterior descending artery (RITA-LAD), left internal thoracic artery-diagonal branch (LITA-diagonal branch), gastroepiploic artery-right coronary artery (GEA-RCA)). Postoperative recovery was smooth, with disappearance of significant pressure difference between both arms (preoperatively, 46mmHg). An angiogram on the 7th postoperative day showed a widely patent axillo-axillary bypass graft along with good flow of all three coronary grafts, in which LITA was visualized well through the axillo-axillary bypass graft. For complex atherosclerotic disease of the proximal aorta and incipient portion of neck vessels associated with severe coronary sclerosis, this technique is a suitable option.
