THE RADIOGRAPHIC DIAGNOSIS OF PULMONARY HYPERTENSION FOLLOWING BLALOCKTAUSSIG SHUNTS IN PATIENTS WITH TETRALOGY OF FALLOT

KENDALL MARR M.D., FRANK A. GIARGIANA JR. M.D., and ROBERT I. WHITE JR. M.D.

Serial chest roentgenograms of 7 patients with tetralogy of Fallot, who developed pulmonary hypertension following subclavian-pulmonary artery anastomosis —Blalock-Taussig (B-T) shunt—were compared to a similar group of patients with normal pulmonary artery pressures following B-T shunts.

The pulmonary hypertensive group developed a disproportionate increase in the central pulmonary vascularity when compared to the peripheral vessels. In contrast to the normotensive group, the cardiothoracic ratio, the right pulmonary artery (RPA) diameter, and the ratio between RPA diameter and transverse cardiac diameter remained elevated or progressively increased following surgery.

It is concluded that progressive enlargement of the central pulmonary arteries following B-T surgery is a reliable sign of the development of pulmonary hypertension. If not recognized early, irreversible changes in pulmonary vascular resistance occur, and the patient is no longer a suitable candidate for total correction.
