[Association of coronary-pulmonary fistula and intercoronary fistula. Apropos of a case].

The authors present the case of a 30-year-old woman admitted to hospital for investigation of a systolodiastolic murmur. Assessment revealed a fistula between the trunk of the left coronary artery and the pulmonary artery, with an aneurysm on the left anterior descending artery (LAD), associated with an intercoronary anastomosis between the left conus artery and the LAD. Thallium myocardial scintigraphy demonstrated reversible decreased uptake in the anterolateroapical region. Simple coronaro-pulmonary fistulas are a rare disease. The positive diagnosis is suggested by echocardiography and confirmed by coronary angiography. The clinical course is generally favourable, except in the presence of complications such as aneurysm, heart failure or coronary insufficiency. This case raises the difficult problem of the operative indication in these young, usually asymptomatic patients.
