Thirty-three patients with pulmonary hypertension (PH) and 16 controls were retrospectively evaluated. The right-to-left peak ventricular transit time (PVTT) determined using cardiac first-pass perfusion MRI was prolonged in patients with PH without left ventricular dysfunction. The degree of PVTT prolongation showed a modest association with right ventricular dilatation and dysfunction. Significant positive correlations were observed between PVTT and pulmonary artery pressures. The PVTT showed moderate sensitivity (65%) and high specificity (90%) for detection of PH. PVTT may be an additional simple tool to evaluate right ventricular dysfunction and pulmonary artery pressure in patients with PH.
