We report a case of arbitrary delayed surgical repair for left ventricular free wall rupture (LVFWR) after acute myocardial infarction with suspected posterior papillary muscle necrosis. The case was a 67-year-old woman who had chest and back pain in the morning, and relapsed in the evening, and was urgently transported. She had an acute lateral wall myocardial infarction on an electrocardiogram and pericardial effusion on transthoracic echocardiography (TTE). She was found to have an obstruction at the origin of the left circumflex branch on coronary angiography. TTE showed low-intensity findings on the head of the posterior papillary muscle, suggesting necrosis of the papillary muscle. For LVFWR, conservative treatment was prioritized and IABP (intra-aortic balloon pumping) management was performed for the purpose of reducing after load because there was concern about papillary muscle rupture (PMR) due to cardiac manipulation and because it was an oozing type and did not disrupt respiratory of circulatory dynamics. On the 7th day after the onset, TTE showed improvement in echo-luminance of the posterior papillary muscle head and gradual increase in pericardial fluid, and a non-suture procedure was performed. She withdrew from the IABP on the third day after surgery and was discharged home on the 12th day.

A 27-year-old woman who suffered loss of consciousness twice after left femoral pain in the 25th week of gestation was referred to the obstetrics and gynecology department of our hospital. A structure with an attachment on the atrial wall was found in both atria on echocardiography, leading us to suspect impending paradoxical embolism (IPE). Judging from the shape of the thrombus in the atria, we thought that there was a high possibility of further embolism although rescue of the baby was feasible via cesarean section, so we decided to carry out emergency surgery. After delivering the infant by cesarean section, we used a heart-lung machine to incise the right atrium under hypothermia and remove the thrombus. As intraoperative esophageal echocardiography showed embolization in the right pulmonary artery, we cut the right pulmonary artery and removed the emboli. After surgery, a femoral vein thrombus was observed on echocardiography of the lower extremity vein, and we inserted an inferior vena cava filter. The patient was discharged on the 16th postoperative day. The situation whereby a thrombus is trapped in the foramen ovale without embolism of the arterial system is the rare pathological condition known as IPE. As no cases of surgical thrombectomy to treat IPE arising from complications of pregnancy have been reported thus far, the case described herein fittingly augments the literature.

A 58-year-old man underwent renal transplantation 26 years previously and had been treated with immunosuppressive drugs. He presented at the local hospital with backache symptoms during the waiting period prior to repair of an abdominal aortic aneurysm. Computed tomography revealed a retroperitoneal hematoma around the abdominal aortic aneurysm. He was admitted to our hospital and emergency straight graft replacement was performed. After clamping of the aorta, we performed axillo-common iliac perfusion to protect the transplanted kidney. The patient recovered without transplanted kidney dysfunction.

For A 38-year-old male diagnosed a congenital complete atrioventricular block in the neonatal period, epicardial lead and pacemaker was implanted through left thoracotomy. Although we tried to implant a pacemaker through the subclavian vein as an adult, it was unsuccessful because of obstruction of the bilateral subclavian vein. For this reason, we performed a pacemaker implantation with transatrial-endocardial lead through the right thoracotomy due to save the generator electric power. This is one of the useful techniques for cases with obstruction of the upper extremity vein.

We describe a case of ruptured coronary artery aneurysm with a coronary artery to a pulmonary artery fistula. An 89-year-old woman with general fatigue and dyspnea was admitted. At the visit she went into shock and was restored by rehydration therapy. Enhanced computed tomography shows a coronary aneurysm (maximum diameter of 50 mm) at the left side of pulmonary artery and mild pericardial effusions. She was scheduled for an emergency operation due to the ruptured coronary artery aneurysm with a coronary artery to pulmonary artery fistula. We performed aneurysmectomy and ligation of the coronary artery to the pulmonary artery fistula under cardiopulmonary bypass. We also reviewed 23 cases of ruptured coronary artery aneurysm with coronary artery extending to a pulmonary artery fistula in Japan. The disease is a rare clinical state and regarded as an indication for emergency surgery.

A 64-year-old man originally underwent Bentall procedure for annulo-aortic ectasia for the first time at the age of 38 years. The surgery was to repair a pseudoaneurysm at the anastomotic site of the left coronary artery by direct closure 11 years after the first Bentall procedure. The anastomosis of the right coronary artery was normal at the time of the first reoperation. However, he had surgery to repair a pseudoaneurysm at the anastomotic site of the right coronary artery 26 years after the first operation ; this was accomplished using the button technique. However, seven months after the second reoperation, he again manifested a pseudoaneurysm at the anastomotic site of the left coronary artery and died of rupture of the pseudoaneurysm. We report the case of pseudoaneurysms at the right and left coronary artery anastomoses that occurred three times after the first Bentall procedure.

We describe a case of an intracardiac foreign body that was treated by surgery. A 27-year-old man sustained a neck injury by a nail fired from a pneumatic nail gun, and was admitted to a hospital. Chest radiography did not show any abnormality, and his injury healed after 1week. A radiography performed during a routine medical checkup after 2 months indicated that a nail was located within the heart. He was subsequently admitted to our hospital for further examinations. Chest computed tomography (CT) revealed the presence of a nail-like foreign body in the right ventricle. We diagnosed the patient with an intracardiac foreign body that was related to the injury sustained 2 months previously, although the underlying mechanism was unknown. He underwent emergency surgery, and the foreign body was removed under cardiopulmonary bypass without any complications. When a rigid substance impacts the body at high speeds, we should consider that some fragments could remain embedded in the body. CT scans are very useful for the diagnosis and identification of foreign bodies.

A 73-year-old man who underwent redo aortic valve replacement due to dysfunction of tissue heart valve developed hypoxemia with bilateral infiltrates on frontal chest radiograph and hypotension shortly after his operation. Due to the presence of progressive hypotension and hypoxemia, we inserted an intra-aortic balloon pump and, furthermore, provided percutaneous cardiopulmonary support. We ruled out cardiogenic pulmonary edema based on information from various examinations, including echocardiography, and subsequently diagnosed possible transfusion-related acute lung injury (possible TRALI). The patient was treated by mechanical ventilation and circulatory support under close supervision, showing a trend of improvement from postoperative day 2 and discontinuing mechanical ventilation on postoperative day 11. The patient made an uneventful recovery and was discharged on postoperative day 50. Cardiac surgery patients are at particular risk for TRALI, so physicians should consider TRALI whenever a patient develops hypoxemia during or shortly after transfusion. Rapid diagnosis and appropriate treatment of TRALI are especially important in cardiac surgery patients.

We clinically reviewed 4 cases of redo cardiac surgery after previous CABG with functioning internal thoracic artery grafts. The patients consisted of 1 man and 3 women (76.8±8.3 years old). Internal thoracic artery (ITA) grafts were used in all patients. Furthermore, 2 mitral valve replacements, 1 aortic valve replacement and 1 replacement of the ascending aorta were performed as redo cardiac surgery. The heart was approached via a anterolateral right thoracotomy in 3 cases. Femoral artery cannulation was used for cardiopulmonary bypass, and the right superior pulmonary vein was exposed to vent the left ventricle in all patients. The functioning ITA grafts were not dissected and were clamped in all cases of the 4 patients, 2 underwent cardioplegic arrest under moderate hypothermia. We could not achieve cardioplegic arrest in 1 patient, and therefore we also performed deep hypothermic fibrillatory arrest. Another patient underwent deep hypothermic circulatory arrest. Serum CK-MB values were elevated in all cases (111.7±89.0 IU/l). However, these elevations did not correlate with intraoperative arrest duration or type of operative procedure performed. Operative mortality was 0%, and all patients were discharged with out any evidence of sequelae. Hypothermic fibrillatory arrest had an effective additional cardioprotective effect for incomplete cardioplegia in these 4 cases. Functioning ITA grafting was not necessary in dissection and clamping for cardioprotection. An anterolateral right thoracotomy provided a safe approach to the heart, avoiding functioning ITA graft injury.

A 37-year-old man who had suffered right chest pain while mowing weeds was transferred to our hospital. A chest roentgenogram revealed a needle-like foreign body overlying the cardiac silhouette and chest CT confirmed an intracardiac foreign body. The patient underwent emergency operation, and a foreign body was removed under cardiopulmonary bypass and performed cardiac repair. A foreign body penetrated right lung and reached it in the left atrial cavity. The patient recovered uneventfully without any symptoms of infections.
