ABSTRACT

Congenital coronary artery fistula is a rare disease and MRI is a promising technique that may be useful to demonstrate the coronary artery tree. We report three patients who underwent cardiac MRI to investigate right coronary artery fistulae. On clinical examination, a continuous murmur was heard along the left sternal border, and chest X-ray showed moderate cardiomegaly with enlargement of right chambers in all patients. Transthoracic Doppler echocardiography showed fistulae in two cases; the third case was not demonstrated by transthoracic or transoesophageal echocardiography. MRI demonstrated the course of the fistulous vessels in all patients. All patients underwent surgical closure of their coronary artery fistulae. MRI may show detailed anatomy of congenital coronary artery fistulae and may be useful as an additional non-invasive method in their investigation.

ABSTRACT

Os derrames pericárdicos, principalmente septados, podem apresentar sérias dificuldades para sua detecçäo e quantificaçäo pela ecocardiografia convencional. A ecocardiografia bidimensional, em auxílio a modalidade M, permite a detecçäo mais correta dos derrames generalizados, pela regiäo apical e subxifóide. Foram estudados 22 pacientes portadores de derrame pericárdico, dos quais quatro eram septados e oito eram pós-operatórios. Estabeleceram-se as diferenças ecocardiográficas entre os diversos tipos e, em 10 casos, relacionou-se com o aspecto radiológico e com o volume de líquido extraído pela punçäo pericárdica ou pela pericariotomia, mostrando uma razoável correlaçäo (r = 0,76). Conclui-se que a ecocarddiografia bidimensional permite a detecçäo de derrames pericárdicos, especialmente os septados situados fora do alcance do sistema convencional, assim como a sua quantificaçäo, com boa confiabilidade
