Stent implantation in surgical cavopulmonary conduit: report of two cases.

Despite advances in Fontan surgery, obstruction in extracardiac ducts may occur and cause clinical deterioration. We report two cases of stent implantation for correction of stenosis in the Fontan surgery. Ascites was a common clinical sign; a patient was protein losing enteropathy.

[Batimastat-eluting stent implantation for the treatment of coronary artery disease: results of the Brazilian pilot study].

Objective: The excellent results obtained with sirolimus (rapamicin)-eluting stents for preventing restenosis have motivated the evaluation of other substances with that property. Batimastat is a highly effective metalloproteinase enzyme blocker, with the potential to reduce the degradation of extracellular matrix and to inhibit the migration of smooth muscle cells, with the consequent capacity to control coronary restenosis.

Methods: From October 2001 to April 2002, 34 patients were prospectively selected with de novo lesions in a native coronary artery > 50% and < 100%, which could be treated with stents of 3 to 4 mm in diameter and 18 mm in length.

Percutaneous stent implantation for treating multivessel coronary disease in patients with and without involvement of the proximal segment of the anterior descending coronary artery.

Objective: To assess coronary stent placement in patients with multivessel coronary disease and involvement of the proximal portion of the anterior descending coronary artery.

Methods: We retrospectively analyzed the in-hospital and late evolution of 189 patients with multivessel coronary disease, who underwent percutaneous coronary stent placement. These patients were divided into 2 groups as follows: group I (GI) - 59 patients with involvement of the proximal segment of the anterior descending coronary artery; and group II (GII) - 130 patients without involvement of the proximal segment of the anterior descending coronary artery.
