RESUMO

A 34-year-old woman was admitted with a history of syncope and a mass was detected in the right atrium (RA) by transthoracic echocardiography (TTE). Preoperative chest computed tomography (CT) also demonstrated an RA tumor measuring 4×3 cm. We performed resection of the RA tumor under cardiopulmonary bypass. Histopathological findings showed that the tumor was an angiomyolipoma. It is well known that angiomyolipomas are most frequently found in the kidney and are associated with tuberous scleroses. There was no evidence of tuberous sclerosis in this case. Primary tumors of the heart are rare. However, there have been a few intracardiac angiomyolipomas reported previously.

RESUMO

A 64-year-old woman with dyspnea on exertion was referred to our hospital. CT revealed type B aortic dissection with 7cm of aneurysm including a thrombus in the false lumen at the distal aortic arch. Four intimal tears at the distal aortic arch were closed directly during hypothermic circulatory arrest, and the descending thoracic aorta was tailored without a prosthetic graft after fixation of the dissecting adventitia to the intima at the distal portion of the false lumen. The postoperative course was uneventful and this patient was discharged on the 22nd postoperative day. Three years after surgery, the postoperative CT revealed no evidence of dilatation of the descending thoracic aorta as far as the abdominal aorta although the dissection of thoracoabdominal aorta remained. This technique is effective as an surgical option for chronic type B aortic dissection to minimize operative stress and complications.

RESUMO

Ten patients, aged 3 to 43 years, with the tetralogy of Fallot underwent <i>in situ</i> pulmonary valve replacement (PVR) 13 times. The implanted valves were a St. Jude Medical prosthesis (3 times) and a bioprosthetic valve (10 times). In 5 patients PVR was performed at the time of radical repair and in the remaining 5 patients PVR was performed after radical repair. Three patients underwent re-PVR at 6 to 13 years after the first PVR. There was one operative death in re-PVR 14 years after the first PVR and one patient died from congestive heart failure 4 years after PVR. In the patients with the tetralogy of Fallot, the rate of PVR in those who had undergone open Brock's operation were significantly higher than that of the patients without open Brock's operation (p<0.05). Actuarial survival rates at 5 years and 10 years were 88.9% and 88.9%, respectively. Rates of freedom from reoperation at 5 years and 10 years were 88.9% and 59.3%, respectively. Although the early operative results are satisfactory, re-PVR is mandatory in the future. Thus the indications of PVR should be considered carefully.

RESUMO

We present a rare case of acute type A dissection which developed compression of the true lumen after starting cardiopulmonary bypass (CPB) with femoral arterial return. In this case, the entry was located in the proximal descending thoracic aorta, and the dissection expanded up to the ascending aorta in a retrograde direction. After starting CPB, the false lumen suddenly enlarged and the true lumen was compressed. We observed those changes by intraoperative transesophageal echocardiography, so the perfusion was stopped immediately. A long arterial cannula (Wessex) was inserted from the left ventricular apex with the tip of the cannula remaining in the true lumen of the ascending aorta, and antegrade perfusion was restarted. After that we could maintain adequate extracorporeal perfusion and the replacement of the total aortic arch was completed uneventfully.

RESUMO

The case presented is a 76-year-old woman with a ruptured abdominal aortic aneurysm. We tried to pass a Fogarty balloon catheter from the left subclavian artery for proximal occlusion of the ruptured aneurysm but failed to inset the balloon into the descending aorta. Although the aneurysm was safely replaced with a gelatine coated dacron graft, she developed cerebral embolism and never regained consciousness and died two months later. Balloon insertion through the subclavian artery may cause complication through dislodgement of atheromatous plaque and may induce cerebral embolism.
