[Imaging of coronary vascular abnormality with aneurysm and arteriovenous fistula using MRI bolus tracking].

Coronary arteriovenous fistulas are very rare findings and predominantly drain into the right atrium or the right ventricle. Echocardiography and x-ray coronary angiography are established methods in the detection of this anomalies. It is reported on a patient, in whom an anomaly with dilatation of the circumflex coronary artery, aneurysma and drainage over an arteriovenous fistula in the right ventricle was observed. By means of magnetic resonance tomography with bolustracking technique the vessel course and the dynamics of perfusion are noninvasive shown beside the imaging using TSE-sequence. The method of multiple injections of 2 ml Gd-DTPA makes the bolustracking technique to an ideal tool for the determination of the individual vessel course, the haemodynamics and draining direction of an coronary anomaly with fistula.
