Foi feita a revisão dos exames de angio-TC de coronárias realizados em pacientes com história de revascularização miocárdica. Todos os exames foram . Palavras-chave: Medição de risco; angiografia Coronária; doença das coronárias; O advento recente da tomografia computadorizada (TC) com múltiplos. In this article we describe the anatomy of the coronary arteries of the heart and some of the anomalies with illustrations and CT-images.
