ABSTRACT
Relatamos caso de rara anomalia de artéria coronária direita saindo do terço médio da artéria descendente anterior com lesão obstrutiva ateromatosa proximal, imediatamente antes da emergência da coronária direita. O paciente foi submetido a angioplastia com implante de Stent na descendente anterior com sucesso. Há relatos de apenas 7 casos desta anomalia de distribuição na literatura, porém nenhum com tratamento de revascularização percutânea.

OBJECTIVE: To assess the in-hospital results and clinical follow-up of young patients (< 50 years) with multivessel coronary artery disease undergoing stent implantation in native coronary arteries and to compare their results with those of patients with single-vessel coronary artery disease. METHODS: We retrospectively studied 462 patients undergoing coronary stent implantation. Patients were divided into 2 groups: group I (G-I) - 388 (84 percent) patients with single-vessel coronary artery disease; and group II (G-II) - 74 (16 percent) patients with multivessel coronary artery disease. RESULTS: The mean age of the patients was 45±4.9 years, and the clinical findings at presentation and demographic data were similar in both groups. The rate of clinical success was 95 percent in G-I and 95.8 percent in G-II (P=0.96), with no difference in regard to in-hospital evolution between the groups. Death, acute myocardial infarction, and the need for myocardial revascularization during clinical follow-up occurred in 10.1 percent and 11.2 percent (P=0.92) in G-I and G-II, respectively. By the end of 24 months, the actuarial analysis showed an event-free survival of 84.6 percent in G-I and 81.1 percent in G-II (P=0.57). CONCLUSION: Percutaneous treatment with coronary stent implantation in young patients with multivessel disease may be safe with a high rate of clinical success, a low incidence of in-hospital complications, and a favorable evolution in clinical follow-up
