  • Title: [Non-invasive diagnosis of a right coronary artery-right ventricle fistula by Doppler echocardiography].
    Author: Salazar J, Placer L, Artal A.
    Journal: Rev Esp Cardiol; 1991 May; 44(5):341-3. PubMed ID: 1852964.
    Abstract:
    A six-year-old girl with an atypical continuous precordial murmur, was suspected of having a coronary arteriovenous fistula. A markedly dilated right coronary artery was revealed by two-dimensional echocardiography. The pulsed Doppler examination showed a diastolic retrograde flow in the ascending aorta, with a normal flow in the left ventricular outflow tract. With the sample volume in the right ventricle a continuous turbulent flow was observed. Color flow mapping showed a turbulent, systolic-diastolic flow in the right ventricle. The fistula was confirmed by cardiac catheterization.
