Clinical Outcomes of Mitral Valve Repair in Dogs With Pulmonary Hypertension Secondary to Myxomatous Mitral Valve Disease.

ABSTRACT:

Background

Myxomatous mitral valve disease (MMVD) can cause pulmonary hypertension (PH). Mitral valve repair (MVR) has been described as a surgical treatment option for MMVD, but the benefit of MVR when PH is present is unknown.

Hypothesis/objectives

To investigate the change in echocardiographic variables and long-term outcomes of dogs with PH secondary to MMVD after MVR.

Animals

Twenty-one dogs with PH secondary to MMVD that underwent MVR.

Methods

Inclusion criteria were MMVD dogs that had a high probability of PH according to the metrics established in the American College of Veterinary Internal Medicine (ACVIM) consensus statement on PH in dogs, and that had two follow-up evaluations. Echocardiographic variables before MVR were compared with the follow-up e
