“…Paravalvular leak (PVL) is a serious complication after mitral valve replacement operations and the factors that are responsible for its occurrence has been reported as; 1-annular calcification, 2-infection, 3-suture technique, 4-size and shape of prosthesis (1)(2)(3). The reported incidence of PVL varies between 7 and 15% (1)(2)(3)(4)(5). One of the most frequent determinants of reoperation after mechanical mitral valve replacement is shown to be PVL (6).…”

“…In patients who have clinical symptomatic, it is possible to find either one or more of the clinical findings of heart failure, hemolytic anemia, arrhythmias, or infective endocarditis (1,4). Many patients with symptomatic PVL may benefit from a second surgical intervention by sternotomy or right thoracotomy for repair of the PVL or replacement of the valve (1,4,6).…”

Objective: A relation between the location of the paravalvular leakage (PVL) and time to reoperation after mitral mechanical valve replacement was investigated. Methods: In an observational retrospective study plan, from 59 patients who underwent reoperation only 47 patients having clinical and echocardiographic follow-up for five years were included into study. Depending on echocardiographic evaluation of location of leak, patients were divided into Group 1 (Leaflet) and Group 2 (Commissural). Demographics, preoperative variables, causes of reoperation, the time period between diagnosis of PVL and reoperation were recorded. Unpaired t test or Mann-Whitney U test were used for comparison of variables between groups. Results: A PVL was diagnosed after a median time of 180 days (range: 1 day-28 years) after the first mitral valve replacement. The median followup period was 5 years (range; 1-16 years). Age, gender, left ventricular ejection function, number and size of leaks did not differ between groups (p>0.05). The time period between diagnosis and reoperation time was longer in Group 1 in comparison to Group 2 (39.0±9.9 vs. 19.5±12.8 months, p=0.002). The 30-day mortality for valve reoperation was 4.3% (2/47). In Group 1, 2 patients (2/21, 9.8%) died whereas, no death was observed in Group 2 (0/26, 0%) (p=0.002). Conclusion:The time period between diagnosis and reoperation was longer in leaflet leak group in comparison to commissural leak group. We suggest echocardiographic evaluation should include location of the paravalvular leakage during follow-up of patients with PVL after mitral valve replacement.

“…It is observed most frequently in mechanical mitral prosthesis [1,2]. Annular calcification, infection, suture technique, size and the shape of the prosthesis may produce this complication [1,2,3]. Redo surgery is generally required in symptomatic patients and in the case of congestive heart failure.…”

Objectives: The aim of this study was to evaluate real-time 3-dimensional transesophageal echocardiography (RT-3D TEE) in the assessment of mitral paravalvular leakage curtaining surgery with a Dacron patch. Methods: RT-3D TEE was used before and after the operation. Results: Repairing a mitral paravalvular leak with Dacron patch curtaining was a useful, simple and new technique with promising feasibility and durability. Conclusions: In selected patients in whom the mitral paravalvular defect is relatively large, and may thus not be suitable for closing with primary suture, Dacron patch curtaining may be feasible for repair guided with RT-3D TEE; both are described for the first time.
