Infracardiac type total anomalous pulmonary venous connection (TAPVC) was diagnosed in a 1-day-old boy. We performed emergency total correction on day 1 and found 2 vertical veins draining to the infracardiac level separately. Each vertical vein was rerouted to the left atrium. On the first postoperative day, an extracorporeal membrane oxygenation was required because of respiratory failure. He died due to cerebral hemorrhage on the 5th day after the operation. Macroscopic findings showed the right sided vertical vein draining to the IVC, and the left sided one to the confluence of the hepatic vein and ductus venosus. Microscopic findings of the lung revealed markedly dilated lymphatics which was suspected as the cause of respiratory failure. Although cases with 2 separate vertical veins are very rare, the precise anatomy of PV return has to be checked intraoperatively when the preoperative identification has not been established.

Tachycardia caused by increased sympathetic nerve activity after cardiovascular surgery can induce an increase in myocardial oxygen consumption and myocardial ischemia. β-Blockers are expected to reduce myocardial oxygen consumption, but traditional β-blockers are long acting so it is difficult to use after cardiovascular surgery. From January 2007 to September 2007, 24 out of 60 patients who underwent cardiovascular surgery were administered landiolol. The average heart rate before landiolol infusion was 99.5±16.5 bpm and decreased to 89.5±10.7 bpm after landiolol infusion (p=0.0008). Average systolic blood pressure before and after landiolol infusion was 109±16 mmHg and 103±13 mmHg, respectively (p=0.15). Average cardiac index (14 patients) before and after landiolol infusion was 3.29±0.83 l/min/m²and 3.26±0.9 l/min/m², respectively (p=0.75). Four patients (17%) had atrial fibrillation during these hospital stay, whereas 20 patients out of 50 patients (40%) who underwent cardiovascular surgery before landiolol was used (from June 2006 to January 2007) had atrial fibrillation (p=0.045). Landiolol can be effective and used safely after cardiovascular surgery.

A 50-year-old man with Marfan syndrome, was given a diagnosis of pseudoaneurysm in an anastomotic site of the left coronary artery after Bentall operation, with severe calcification. He was successfully treated with reanastomosis of a new graft to the left main trunk by the removal of a calcified intima. Coronary artery bypass grafting was not possible because his coronary arteries were covered with thickened fatty tissue due to a previous omental flap procedure for mediastinitis, and therefore we chose left main trunk coronary angioplasty. The whole calcified intima was excluded with a dissector and resected at both ostias of the left descending artery and left circumflex artery. An 8-mm woven Dacron graft was anastomosed at the left main trunk by large stitches of adhesive tissue around the adventitia, to the inside of the lumen of the left main trunk. The patency of the left main trunk was confirmed by CT and he was discharged in a good condition. Close observation is needed for long-term morbidity.

A 39-year-old woman, who had undergone aortic valve replacement with a Carpentier-Edwards pericardial bioprosthesis 16 years previously, was admitted to our hospital with a diagnosis of acute heart failure due to acute aortic regurgitation. An emergency operation was undertaken with the patient in a state of shock due to sudden cardiac arrest. The ascending aorta was cross clamped, and cardiac arrest was induced, and aortotomy was done. One of the leaflets of the CEP was entirely collapsed and dislocated to the LV side, which caused acute aortic regurgitation. Although there was no evidence of endocarditis, slight calcification and small perforation of the leaflet of the valve was observed. Aortic valve replacement was performed with a mechanical heart valve but it was impossible to wean from ECC, and therefore we additionally performed mitral valve annuloplasty with a prosthetic ring for moderate mitral regurgitation. After 4 h cardiopulmonary assistance, ECC was successfully withdrawn. She was discharged in a good condition an post operative day 29th.

Papillary muscle rupture is one of the common complications of acute myocardial infarction. We report a case of 77-years-old man with an acute posterior papillary muscle rupture without obvious coronary artery disease. The patient presented with cardiogenic shock and pulmonary edema. Emergency coronary angiogram showed no obstruction in coronary arteries. An echocardiogram and right heart catheterization data suggested acute mitral regurgitation caused by ruptured posterior papillary muscle. Percutaneous cardiopulmonary support was induced because of his unstable hemodynamics, and then emergency mitral valve replacement was performed. Intraoperative findings suggested some ischemic changes in the posterior papillary muscle. Pathologically, both old and new ischemic lesion presented in the same papillary muscle. Moreover, severe thickening of a small vessel wall was noted. This case presented one of the possible mechanisms of so-called idiopathic papillary muscle rupture.

We treated two cases of Stanford type A acute dissecting aortic aneurysm with the adventitial inversion technique. Both case 1) a 65-year-old woman and 2) a 74-year-old woman underwent emergency operation. After cardiopulmonary bypass was established as usual, the diseased aorta was resected, and the intima was trimmed about 10mm shorter than the transected adventitial line in both proximal and distal ends. After GRF glue was employed, the adventitia was inverted inward over the false-lumen, and then tacked with horizontal continuous mattress sutures using 5-0 polypropylene. The graft was then anastomosed with continuous sutures using 3-0 polypropylene. No bleeding occurred from the anastomosis site in both cases. This method was completed without the use of artificial reinforcement, nevertheless patent anastomosis was possible. This simple method was easily performed and proved to be safe and useful.

Coarctation of the aorta (CoA) complicates with right aortic arch (RAA) is very rare, and its surgical treatment in the neonatal period is extremely uncommon. We performed surgical repair for a 27-day-old boy given a diagnosis of double outlet right ventricle (DORV) and CoA with RAA. The procedures consisted of an arterial switch, intra-ventricular re-routing, aortic arch reconstruction using an equine-pericardial roll and right ventricular outflow reconstruction (RVOTR) with autologous pericardium. We performed re-RVOTR 41 days after the operation because the autologous pericardium used for RVOTR showed aneurysmal dilatation. After the second operation, this patient has done well.

Although aortic annular abscess and rupture of the sinus of Valsalva are known as complications of infective endocarditis, few cases in children have been reported. We report a surgical case of a 6-year-old girl with active infective endocarditis complicated with an annular abscess and pseudoaneurysm of the sinus of Valsalva. The patient presented progressive symptoms of heart failure and a subsequent echocardiogram demonstrated severe aortic regurgitation. A computed tomography indicated pseudoaneurysm of sinus of Valsalva and an emergency operation was performed. At operation, a bicuspid aortic valve with vegetation was noted. The annular abscess caused a large tissue defect of the left coronary sinus of Valsalva and formed a pseudoaneurysm. The infected lesion was resected completely. The defective aortic annulus and sinus of Valsalva were repaired with a bovine pericardial patch and aortic valve was replaced with a mechanical valve. The postoperative course was uneventful and the patient was discharged after adequate antibiotic treatment.

We encountered two cases of infected aortic abdominal aneurysm with spondylodiskitis. Both cases were diagnosed on the basis of fever, back pain and pulsatile abdominal mass. A 69-year-old man, case 1, underwent in situ reconstruction 1 year from the onset, because the infection was controllable by antibiotics and he had diabetes mellitus. A 68-year-old man, case 2, underwent operation while his infection was still active, because of paralysis of the bilateral lower extremities, aggravated by invasion of the vertebrae by the abscess. To prevent artificial graft infection, he underwent axillo-femoral bypass, which was extra-anatomical reconstruction, after the infected aneurysm and vertebrae were removed during aortic clamping above the aneurysm and bilateral common iliac arteries. Each stump was sutured and anterior fixation of the vertebrae was performed using an iliac bone graft. The postoperative course of both patients was successful. These cases suggest that the timing and procedure of the operation for infected aortic abdominal aneurysm with spondylodiskitis should be decided depending on the activity of infection, complications, age and activity of daily life of patients.
