Cutting balloon angioplasty for intrastent restenosis treatment.

We describe here two patients with angiographic diagnosis of intrastent restenosis and regional myocardial ischemia. One stent restenosis was located in a native coronary artery and the other in a vein graft. Both were treated with cutting balloon angioplasty (CBA), inflated at low pressures. Angiographic success was obtained and both patients were discharged in the day after the procedure. Cutting balloon angioplasty using low inflation pressures achieved important luminal gains, in these two cases of intrastent restenosis. Further studies are necessary before the effectiveness of this procedure can be precisely defined.

Nonocclusive intestinal ischemia and necrosis after correction of interatrial communication with cardiopulmonary bypass. A rare and catastrophic complication.

The authors present a case of massive, nonocclusive intestinal ischemia and necrosis after surgery for correction of interatrial communication with cardiopulmonary bypass in a 22-year-old woman. This is an extremely serious complication that generally occurs in older patients. The literature mentions its occurrence in patients subjected to aortic valve replacement who have low cardiac output and in patients undergoing myocardial revascularization. Its occurrence in a young person with simple congenital cardiopathy is rare.

[Pseudo-false aneurysm of the left ventricle simulating pulmonary neoplasm. A case report]. / Pseudofalsoaneurisma do ventrículo esquerdo simulando neoplasia pulmonar. Relato de caso.

The case of a 74 year old woman with pseudo-false aneurysm of the left ventricle after a silent myocardial infarction stimulating left pulmonary neoplasm is presented. Special emphasis in given to the uncommon aspects of the case, its rarity and the association of the pseudo-false aneurysm with a true aneurysm of left ventricle.

[Surgical approach in bacterial endocarditis of the tricuspid valve in children. Report of 2 cases]. / Abordagem cirúrgica na endocardite bacteriana da valva tricúspide em crianças. Relato de dois casos.

The two techniques usually employed for the surgical treatment of tricuspid valve endocarditis are valve replacement or simple valve excision without valve replacement. A third more conservative procedure consists of resection of the vegetation ("vegetectomy") and leaflet repair, if necessary. Valve excision without valve replacement is described in adult patients especially in addicts of intravenous drugs, with normal ventricular function. Two cases of tricuspid valve endocarditis in children with interventricular communication successfully treated by "vegetectomy" and valve excision without valve replacement are reported. In the first case, surgery was performed during acute infection. Contrarily in the other case there was evidence that cure had been obtained, but still the prosthesis was not implanted due to the excellent hemodynamic status at the moment, and to abbreviate bypass time due to the preoperative conditions of the child. The uncommon approach to these two cases of tricuspid valve endocarditis in childhood motivated this presentation.

Nonfunctioning paraganglioma of the posterior mediastinum. Case report.

A case of nonfunctioning paraganglioma of the posterior mediastinum in a 20-year-old white man is presented. The diagnosis of aorticosympathetic paraganglioma (Glenner-Grimley classification) was established by histologic examination after surgical removal of the tumor.
