Key Words: arterio-arterial fistula; pulmonary artery; congenital abnormalities.

Adolescent, 13 yrs, with slight fatigue and cyanosis since birth. No heart failure, oxygen saturation > 80% and continuous murmur +/++ at the inferior left sternal border. Chest x-ray showed higher caliber vessels to the left. Left pulmonary artery hypertension (90/45-60 mm Hg and 7.8 UW) and normotension to the right (20 mm Hg, 1.8 UW). Left pulmonary artery originated from the ascending aorta and the right pulmonary artery filled through a fistula of the right coronary artery to the pulmonary trunk. Different levels of pulmonary artery pressure caused procedure difficulty through the unification of the two systems. The stable clinical picture led to the expectant conduct.
