ABSTRACT
Transcatheter mitral valve replacement (TMVR) has emerged as a feasible alternative to surgical reoperation in failed bioprostheses and rings. Residual mitral regurgitation following TMVR can present as a valve?in?valve paravalvular leak (PVL) and is associated with increased morbidity and mortality. Current therapies for valve?in?valve PVL are limited. We present a case of a symptomatic patient with severe valve?in?valve PVL after TMVR for a previous surgical bioprosthesis leak, who then underwent a second TMVR as a valve?in?valve?in?valve implantation with a 29 mm Edwards? SAPIEN 3 valve via transseptal approach using three?dimensional (3D) echocardiography. This unique case highlights the complexity of this clinical entity and recognizes 3D transesophageal echocardiography as a valuable tool to guide valve?in?valve PVL closures.echocardiography
ABSTRACT
Abstract Background: Paravalvular leak (PVL) is a frequent and important complication after surgical valvular replacement that can cause heart failure and hemolytic anemia and is associated with poor clinical outcomes. Surgical reoperation has been the standard treatment, but it is associated with high morbidity and mortality. Transcatheter closure is a therapeutic alternative. The aim of the present study is to analyze the feasibility and the short- and medium-term outcomes of the transcatheter closure of PVLs. Methods: Single-center registry of consecutive patients with post-surgical PVLs that underwent transcatheter closure, between January 2006 and December 2016. Efficacy and safety results were analyzed during the procedure and at 6-month follow-up. Results: Twenty-one PVLs (15 mitral, 5 aortic, and 1 tricuspid) were closure during 20 procedures. In the initial echocardiography, 91% of the leaks were severe. The most used device was the Amplatzer Vascular Plug III® in 10 procedures (50%). The three-dimensional transesophageal echocardiography was used in 70% of cases. The device was successfully implanted in 95% of cases, a regurgitation reduction ≥ 1 grade was achieved in 95% of the cases, and the clinical success was 79%. Six-month survival was 100%; however, three cases required valvular surgery (15%). Conclusions: Transcatheter closure of PVLs is a feasible and safe procedure with high rates of technical, echocardiographic, and clinical success in the short and medium term. It is an adequate therapeutic alternative, mainly in high surgical risk patients and multiples comorbidities.
Resumen Introducción: La fuga paravalvular es una complicación frecuente e importante posterior al reemplazo valvular quirúrgico que puede ocasionar insuficiencia cardiaca, anemia hemolítica y se relaciona con malos resultados clínicos. La reintervención quirúrgica ha sido el tratamiento habitual, pero se acompaña de alta morbimortalidad. El cierre transcatéter es una alternativa terapéutica. El objetivo del presente estudio es analizar la factibilidad y los resultados a corto y mediano plazo del cierre transcatéter de fugas paravalvulares con dispositivos oclusores. Métodos: Registro unicéntrico de una serie consecutiva de pacientes con fugas paravalvulares posquirúrgicas que fueron cerradas vía transcatéter con dispositivos oclusores, entre enero del 2006 y diciembre del 2016. Se analizaron los resultados de eficacia y seguridad durante el procedimiento y a seis meses. Resultados: Se trataron 21 fugas paravalvulares (15 mitrales, 5 aórticas y 1 tricuspídea) durante 20 procedimientos. El 91% de las fugas fue grave en la ecocardiografía inicial. El dispositivo utilizado con más frecuencia fue el Amplatzer Vascular Plug III® en 10 procedimientos (50%). Se utilizó ecocardiografía transesofágica tridimensional en 70% de los casos. Se logró implantar el dispositivo con éxito en el 95% de los casos; se consiguió una reducción ≥ 1 del grado de regurgitación en el 95% de las veces y se alcanzó el éxito clínico en el 79%. A seis meses la supervivencia fue del 100%; sin embargo, tres casos requirieron cirugía valvular (15%). Conclusiones: El cierre transcatéter de fugas paravalvulares es un procedimiento factible, seguro y con tasas elevadas de éxito técnico, ecocardiográfico y clínico a corto y mediano plazo. Es una alternativa terapéutica adecuada, en particular en pacientes considerados de alto riesgo quirúrgico y múltiples comorbilidades.

Objective@#To investigate the feasibility and efficacy of percutaneous closure of paravalvuar leak (PVL) in patients after heart valve replacement surgery using Amplatzer vascular plug Ⅲ (AVP Ⅲ).@*Methods@#In this retrospective study, consecutive PVL patients after heart valve replacement surgery receiving percutaneous closure with AVP Ⅲ in Beijing Anzhen hospital between March 2017 and October 2018 (n=21) were enrolled.The preoperative and intraoperative data and short-and mid-term outcome results were analyzed.@*Results@#Theage of patients in this cohort was (54.9±11.7) years, and there were 12 (57.1%) male patients. There were 8 patients (38.1%) post mitral valve replacement, 4 patients (19.0%) post aortic valve replacement and 9 patients (42.9%) post double valves replacements.There were 14 cases (66.7%) of mitral valve PVL,6 cases (28.6%) of aortic valve PVL, and 1 case (4.8%) of double valves PVL.Successful device deployment was accomplished in 18 defects from 17 PVL patients. Technical successful rate of mitral valve PVL closure and aortic valve PVL closure was 12/15 and 6/7,respectively. One patient received surgical repair due to procedure-induced femoral pseudoaneurysm.There were 17 cases of severe PVL and 1 case of moderate PVL before procedure, and there were 2 cases of moderate PVL, 6 cases mild PVL, and PVL disappeared in 10 cases after procedure (P<0.01 vs. pre-procedure). The follow-up time was (8.3±4.7) months. There were 10 cases (58.8%) of New York Heart Association (NYHA) function grade Ⅲ and 7 cases (41.2%) of NYHA function grade Ⅳ before procedure, and there were 12 cases of NYHA function grade Ⅰ(70.6%) and 5 cases (29.4%) of NYHA function grade Ⅱ post procedure (P<0.01). Post procedure, there was no displacement of the occluder and heart valve movement was not affected,and there was no new hemolysis or hemolysis worsening.@*Conclusion@#Percutaneous closure of PVL in patients after heart valve replacement surgery with AVP Ⅲ is feasible, and associated with favorable short-and mid-term clinical outcomes.
ABSTRACT
La fuga paravalvular es una complicación relevante después del cambio valvular quirúrgico. Tradicionalmente la cirugía ha sido considerada el tratamiento de elección, sin embargo, conlleva una elevada morbimortalidad, así como un incremento en el riesgo de desarrollar fuga paravalvular recurrente. El tratamiento percutáneo de la fuga paravalvular se presenta como una atractiva alternativa. Dicho tratamiento ha sido posible por la capacidad actual de integrar múltiples modalidades de imagen que han ayudado a definir la anatomía del defecto y a planificar y guiar el procedimiento de cierre percutáneo, resultando en mejores desenlaces. El Amplatzer® Vascular Plug III (St. Jude Medical) es el primer dispositivo específicamente diseñado para el cierre percutáneo de la fuga paravalvular con resultados prometedores. Presentamos la imagen ecocardiográfica transesofágica tridimensional del resultado exitoso de cierre percutáneo de una fuga paravalvular mitral residual con un dispositivo Amplatzer® Vascular Plug III (St. Jude Medical), después de un procedimiento inicial de cierre percutáneo con un dispositivo Amplatzer® Duct Occluder (St. Jude Medical).
Paravalvular leak is a significant complication after surgical valve replacement. Traditionally, redo surgery has been considered the treatment of choice, but is associated with high morbidity and mortality as well as increase risk of developing new leaks. Percutaneous treatment of paravalvular leak appears as an attractive alternative. Such treatment has been made possible by the current ability to integrate multiple imaging modalities that have helped to define the anatomy of the defect and planning and guiding the percutaneous closure procedure, thus resulting in better outcomes. The Amplatzer® Vascular Plug III (St. Jude Medical) is the first device specifically designed for percutaneous closure of paravalvular leak with promising results. We present the three-dimensional transesophageal echocardiographic images of a successful outcome of percutaneous closure of a residual mitral paravalvular leak with an Amplatzer® Vascular Plug III device (St. Jude Medical), after an initial procedure of percutaneous closure with an Amplatzer® duct occluder (St. Jude Medical).

The paravalvular leak after redo mitral prosthetic valve replacement is rare but serious complication when it does happen. This condition should be corrected surgically to increase life span and improve symptoms. But simple closure or patch closure of paravalvular leak are not effective in cases of weak annulus or broad defect. We report 3 cases of trido mitral valve replacement using mechanical valve with its sewing ring expanded by a collar of Dacron sheet. The prosthetic sewing ring is anchored on the weak mitral annulus with multiple interrupted sutures, while the Dacron collar is contineuously sutured to the left atrial wall for blood tight sealing. All of the three cases showed event free postoperative course.

We experienced a casts of prosthetic mitral paravalvular leak after redo DVR. As far as nonstructural dysfunction is concerned, the prosthetic paravalvular leak is not the result of prosthetic valve endocarditis, but is due to technical difficulties at the time of operation, either residual calcification or poor native tissue. Occasionally paravalvular leaks, particulary around mitral prostheses, may be silent. Paravalvular leaks are usually repaired when there is significant anemia or hemodynamic compromise. At reoperation, some of theses leaks can be repaired simply by patch losure around the paravalvular leak without placing additional suture or explanting the valve.
