“…Hwang and associates (2) reported that 74% of PVLs occur during the first postoperative year. It is extremely rare for PVLs to occur more than 20 years after MVR (1,3,5). The longest interval between the latest MVR and diagnosis of a new PVL in our series was 29 years, which exceeds the longest interval (27 years) reported to date (3).…”

“…It is extremely rare for patients to develop PVL decades after MVR (1). Previous reports have cited the longest period between MVR and the diagnosis of a new PVL to be 27 years (3). This retrospective review was conducted at our tertiary center to study the outcomes of 6 patients who underwent reoperative surgery for mitral PVLs occurring more than 10 years after the latest MVR.…”

Surgical management of very late paravalvular leaks after mitral valve replacement: a single institutional experience

Most mitral paravalvular leaks (PVLs) occur during the first year after mitral valve replacement (MVR). This report describes the surgical management of 6 patients who developed very late mitral PVLs.The median interval between MVR and initial diagnosis of PVL was 16.5 years. All patients presented with congestive cardiac failure and haemolytic anaemia. The median EuroSCORE II was 9.5%. Two patients (33%) had failed attempts at transcatheter closure. Five patients underwent suture repair of the PVL. One patient underwent MVR after removal of the previous prosthesis. No in-hospital mortalities occurred. At latest follow-up (median 3.3 years), 5 patients (83%) were asymptomatic with no residual PVL. Haemolytic anaemia persisted in 1 patient with a mild residual PVL. PVL occurring decades after MVR is a rare but serious complication. Reoperative surgery can be performed in these high-risk patients with satisfactory early and midterm outcomes. J Thorac Dis 2016;8(9):E952-E956 jtd.amegroups.com images were available for 5 patients (Figure 1). The median EuroSCORE II was 9.5% (range: 4.0% to 42.2%). The median left ventricular ejection fraction (LVEF) was 61% (range: 55% to 67%).Two patients had undergone unsuccessful percutaneous closure of PVL, which failed due to either significant residual regurgitation or the closure device interfering with the existing mitral prosthesis. One patient who received 2 occluder devices required emergency surgery due to cardiogenic shock, resulting from a closure device being caught between the leaflets of the mitral prosthesis. Five patients with discrete PVLs in the presence of a calcified mitral annulus underwent direct suture repair without removal of the existing mitral prosthesis. One patient with multiple PVLs at various sites along the sewing ring underwent MVR after extirpation of the previous prosthetic valve. Concomitant procedures were performed in 4 patients ( Table 1). The median aortic cross-clamp and cardiopulmonary bypass times were 50 minutes (range, 42 to 119 minutes) and 99 minutes (range, 72 to 196 minutes), respectively.There were no in-hospital mortalities. Postoperative complications are listed in Table 1. No patients suffered from postoperative stroke, myocardial infarction or required insertion of a permanent pacemaker. Upon discharge from hospital, five patients (83.3%) had no residual PVL and 1 patient (16.7%) had mild residual PVL.All patients were reviewed at our institution during scheduled clinic consultations. The median follow up period was 3.3 years (range: 1.9 to 4.8 years). There were no late mortalities. Five patients (83.3%) were in NYHA class I and had no recurrence of haemolytic anaemia. Four patients (66.7%) had no recurrence of PVL and two patients (33.3%) had mild PVL during follow-up echocardiographic assessment ( Table 1). In the patient who underwent salvage surgery following failed transcatheter repair, haemolysis persisted despite surgical correction, due to a turbulent jet flowing through a mild residual PVL. The patient op...
