Paravalvular regurgitation (PVR) is an uncommon complication of mitral valve replacement (MVR). Although severe PVR is almost always repaired immediately when recognized during surgery, there are little data available on the management of patients with mild and moderate PVR. This study includes eight patients with mild (n = 6) and moderate (n = 2) PVR identified by transesophageal echocardiography at the time of MVR who were treated conservatively. Clinical and echocardiographic follow-up was obtained at a mean of 16.3 months. Two of six patients with mild PVR at the time of MVR and two of two patients with moderate PVR at the time of MVR deteriorated clinically and echocardiographically over time. We suggest that moderate PVR should be corrected at the time of valve-replacement surgery, if this can be performed without high operative risk. Mild PVR should probably also be repaired, if this can be performed at low risk, because some will progress. Patients left with mild PVR after surgery, or patients in whom PVR is recognized only after surgery, should be followed up carefully with serial clinical and echocardiographic examinations.
