Pulmonary dysfunction after lung transplantation: the dilemma of coexisting mitral regurgitation.

ABSTRACT

A case of MR progression after single-lung transplant as a significant contributor to postoperative respiratory failure is reported. Pre-existing MR may progress due to the decompressive effects of lung transplantation on RV dimension and consequent alteration of MV geometry. This case highlights the importance of intraoperative TEE findings, especially pertaining to valvulopathies in the setting of lung transplantation. Postoperative surveillance of significant findings is imperative when any new symptoms are being investigated.
