Pulmonary vein stenosis in heart transplant patients.

PVS is a rare complication that is associated with patients who undergo HT during infancy. PVS develops soon after HT and screening should occur accordingly. Interestingly, high donor-to-recipient weight and TCV ratios are not necessarily associated with the development of PVS. Further work will need to be performed in order to determine the significance of PVS in post-HT patients.
