Pulmonary hypertension remains a major mortality factor of many types of congenital heart disease. Cardiopulmonary transit time as measured by time-resolved MR angiography, is significantly prolonged in congenital heart disease patients complicated with pulmonary hypertension and correlates well with ventricular volumetric indices of right heart failure. These measurements may provide a useful adjunct tool for assessing and following pulmonary hypertension and early right-sided heart failure in this group of patients.
