A 58-year-old man who complained of dyspnea on effort was given a diagnosis of decompensated congestive heart failure. Echocardiography revealed severe aortic regurgitation and cardiomegaly. We decided to perform aortic valve replacement with a mechanical valve, however his past history made us suspicious of allergy to metal. From his previous patient records, we determined he was allergic to many metals : gold, iron, platinum, cobalt, chrome, bronze, and zinc. Newly performed skin patch tests showed positive reactions to aluminum, tin, palladium, indium, iridium and stainless steel. We selected a CarboMedics mechanical valve made of nickel-titanium alloy. Aortic valve replacement with a 27-mm CarboMedics mechanical valve was performed by median sternotomy. At sternum closure, we used polyester non-absorbable suture thread, instead of surgical steel wire, because it contains stainless steel. His postoperative progress was good and he was discharged on the 10th postoperative day. One year after surgery he is doing well without any allergic symptoms.

A 79-year-old man who had undergone aneurysmectomy and graft replacement for an abdominal aortic aneurysm developed abdominal distension and massive hematuria. A computed tomography (CT) scan revealed the presence of anastomotic pseudoaneurysms and an ureteroarterial fistula between the ureter and iliac artery (distal anastomotic pseudoaneurysm). On admission, the patient's vital signs were stable. The patient was considered a high-risk case for open surgery because of his renal dysfunction which required dialysis, chronic heart failure and hostile abdomen. We initially recommended open surgery because of possible graft infection, however, the patient refused to undergo the high-risk open surgery. We performed emergency surgery for the ureteroarterial fistula via coverage with off-label use of the stent-graft leg. Intraoperative angiography revealed that there was no leakage. After 1 month, we confirmed that the inflammatory laboratory data was normalized, subsequently, we performed endovascular re-intervention for the proximal aortic anastomotic pseudoaneurysm. The endoleak was finally repaired after off-label use of the stent-graft (aortic cuff exclusion) twice within 2 months. The patient did not develop any operation-related adverse events for 4 months, but subsequently he died of pneumonia that developed from a common cold. Thus, we successfully performed endovascular treatment for a high-risk patient with an ureteroarterial fistula and pseudoaneurysms, without any surgery-related infection.

A 67-year-old man had been followed up in our cardiology clinic for ischemic foot, and routine echocardiography revealed an 8×9mm highly echogenic mass on the mitral posterior leaflet. Because of the high thromboembolic risk, open-heart surgery was scheduled for surgical treatment of the tumor. His preoperative coronary angiogram showed 3 vessel disease. Coronary artery bypass grafting and tumor removal were performed consequently. His postoperative course was uneventful and the lesion was pathologically diagnosed a papillary fibroelastoma. No recurrence has occurred one year after the operation. Surgical treatment of cardiac tumors is mandatory for preventing embolism regardless of the size and location. Most of the tumors on cardiac valves are papillary fibroelastomas and recurrence of this tumor has not been reported so far. When the tumor is attached to a mitral leafet, simple tumor resection, with or without mitral valve repair, is justified instead of performing mitral replacement with en bloc resection of tumors and the entire leaflets.

Cardiac injury following blunt chest trauma requires immediate transportation, correct diagnosis and early surgical treatment. We present 2 cases of rare cardiac rupture, right auricular laceration and multiple ruptures of vena cava, respectively. Case 1: An 18-year-old male driver was transported to a local hospital in a state of shock immediately after a traffic accident. Chest CT demonstrated cardiac tamponade. After temporary hemodynamic improvement by pericardiocentesis, he was referred to our hospital. Since his blood pressure decreased below the measurable threshold in the ICU, he was transferred to the OR after emergency subxiphoid pericardial drainage. On opening the pericardium after full sternotomy, the right atrial appcndage laceration was found, about 1cm in length, and was sutured easily without cardiopulmonary bypass or any transfusion. Postoperative recovery was uneventful. Case 2: A 19-year-old male driver was directly transferred in an apneic shock state. Chest CT revealed cardiac tamponade. Full sternotomy was promptly carried out in the ICU after cardiopulmonary resuscitation (CPR) and subxiphoid pericardial drainage. Caval injury was found, 2cm in length, in both the superior vena cava (SVC) and intrapericardial inferior vena cava (IVC). His circulatory state was restored after the repair of these caval injuries without cardiopulmonary bypass; however, he died from severe brain damage postoperatively. In summary, blunt rupture of the right heart could be saved by prompt transport with airway assist, pericardial drainage, and proper surgery.

A 46-year-old woman who originally presented acute abdomen was refferect to us. Her CT scan and echogram showed no abnormal findings in her abdomen. However, A 25-mm tumor-like mass was observed in her right atrium and right lower lobe. Based on the concern that the cardiac tumor might be a risk for embolic events, the tumor in her right atrium was resected under cardiopulmonary bypass in a semi-emergency manner. It was diagnosed as malignant lymphoma of B-cell type by histological examination. Two days after operation, she started to have abdominal pain and CT scan showed free air and a significant amount of effusion in her abdomen. Emergency laparotomy was performed and a single perforation with a tumor mass was observed in her small intestine. Segmentectomy was performed and her postoperative course since then was uneventful. Fifteen days after her initial operation, she was referred to the regional hematology center for chemotherapy. Primary cardiac lymphoma was classically defined as an extranodal lymphoma involving only the heart and/or pericardium; however the currently accepted definition is lymphoma with the vast bulk of the tumor intrapericardial even with small secondary lesions elsewhere. According to this recent definition, several cases with extensive extracardial involvements have been reported as primary cardiac lymphoma and our case marginally could be considered primary. Certain cutoffs must be proposed to quantify extracardiac disease in defining primary cardiac lymphoma.
