EchoNavigator^® technology facilitates transapical mitral paravalvular leak closure: a case report.

ABSTRACT:

Background

Catheter-based closure has emerged as a less invasive alternative to surgery in high-risk patients with paravalvular leak (PVL) and clinically significant regurgitation with feasibility and efficacy demonstrated in multiple studies.

Case summary

A 72-year-old female with a past history of long-standing rheumatic heart disease underwent mechanical mitral valve replacement in 2008. Ten years later, redo surgery was performed due to a worsening mitral PVL and the leakage was closed by direct pledget-supported sutures, preserving the mechanical valve. She was recently admitted again for haemolytic anaemia and congestive heart failure (New York Heart Association Classes III-IV) due to a recurrent mitral PVL. We report our initial clinical experience using a novel software solution (EchoNavigator^®-system) for intuitive guidance during a catheter-based transapical mitral PVL closure.

Discussion

Transapical mitral PVL closure with a specifically designed device demonstrated in our case to be a better option than redo surgery. Recently introduced fusion imaging modalities enhanced visualization of soft tissue anatomy and device location improving enormously the results of this challenging intervention.

Management of severe haemolytic anaemia due to residual small mitral paravalvular leak post-percutaneous closure: a case report.

Project description:BackgroundHaemolytic anaemia is a complication of paravalvular leak (PVL). The correlation between the size of the leak and the severity of haemolysis is unclear. Small leaks can cause severe haemolysis, whereas significant leaks may cause no haemolysis.Case summaryWe report the case of a 40-year-old male who underwent mechanical mitral and aortic valve replacement 20 years ago. In the last 3 years, the procedure was repeated three times due to infective endocarditis. He presented with severe shortness of breath. A transoesophageal echocardiogram with three-dimensional surgical view showed that both discs of the mechanical mitral valve opened sufficiently but a severe PVL had occurred at the 9-12 o'clock position. The location of the mitral valve was abnormal, the sewing ring was inserted high at the mid-interatrial septum. The mechanical aortic valve functioned well. Closure of the transcutaneous PVL was accomplished with two percutaneously implanted devices, leaving a small leak in between. After closure, he developed haemolytic anaemia (haemoglobin: 6 g/dL, lactate dehydrogenase: 1896 units/L, reticulocyte count: 4.6%). He then received 16 units of packed red blood cells. He developed acute kidney injury and was started on haemodialysis. We then installed two additional devices to completely close the mild residual leak and another device to resolve the bidirectional transseptal defect. After 2 days, his renal function returned to normal and anaemia improved (haemoglobin: 9.1 g/dL).DiscussionMild residual paravalvular leak can cause severe haemolytic anaemia that is correctable via percutaneous closure of the leak.

Percutaneous Closure of Mitral Paravalvular Leak: Long-Term Results in a Single-Center Experience.

Project description:BackgroundParavalvular leak occurs in 5-17% of patients following surgical valve replacement, more often in mitral position. The prognosis without treatment is poor. Percutaneous device closure represents an alternative to repeat surgery. The objective of this work is to evaluate the medium and long-term results in the percutaneous closure of PVL in mitral prosthesis.MethodsThis observational study is based on a retrospective registry including consecutive mitral PVL cases undergoing percutaneous closure at a single tertiary-care center from April 2010 to December 2020. The safety and efficacy results of the procedure, at 90 days and in the long term, were analyzed. Also, predictors of procedure failure and long-term events were identified.ResultsA total of 128 consecutive mitral paravalvular leak closure procedures were included. Technical success was achieved in 115 (89.8%) procedures. The presence of multiple PVLs was the sole factor that independently predicted procedural failure. Median follow-up of our sample was 41.8 months (mean 47.7 ± 35.7 months). Underlying hemolytic anemia as the indication for PVL closure, a recent admission for decompensated HF, and lack of improvement in functional class emerged as consistent predictors of MACE and death during long-term follow-up, while lack of procedural success during the first PVL procedure and chronic kidney disease were also associated with MACE during follow-up.ConclusionsPercutaneous mitral PVL closure displayed high technical and procedural success rates, with an acceptable safety profile, in a high-risk population. Percutaneous mitral PVL closure achieved an improvement in short- and long-term functional class and a reduction of hemolysis in the vast majority of patients. In addition, long-term survival in our study was good, in particular for patients undergoing successful PVL closure procedures.

Percutaneous closure of a paravalvular leak from a prosthetic mitral valve dehiscence in a young high-risk patient: case report.

Project description:BackgroundParavalvular leak (PVL) is a common, serious complication related with prosthetic valve replacement. Although surgical closure reoperation is the choice of treatment, percutaneous device closure is a good alternative with good results in patients with very high surgical risk.Case summaryIn this case report, we present the percutaneous closure of PVL of mitral valve replacement (MVR), in a patient with cardiogenic shock who failed conservative medical treatment and was deemed inoperable due to recurrent operations. Successful closure of the PVL with the use of the four consecutive PVL closure devices was performed under general anaesthesia with guidance of 2D and 3D transoesophageal echocardiography. The procedure was performed with no complications and the patient has remained asymptomatic after 10 months following the PVL closure procedure with marked improvement in her NYHA class and echocardiographic values.DiscussionPercutaneous PVL closure is a very challenging and high clinical skills requiring procedure, but has a good success and low complication rate in high-risk patients. It is not a standard procedure and the type and size of device should be tailored for each patient with a good 2D and 3D echocardiographic guidance.

Multimodality Cardiac Imaging for Procedural Planning and Guidance of Transcatheter Mitral Valve Replacement and Mitral Paravalvular Leak Closure.

Project description:Transcatheter mitral valve interventions are an evolving and growing field in which multimodality cardiac imaging is essential for diagnosis, procedural planning, and intraprocedural guidance. Currently, transcatheter mitral valve-in-valve with a balloon-expandable valve is the only form of transcatheter mitral valve replacement (TMVR) approved by the FDA, but valve-in-ring and valve-in-mitral annular calcification interventions are increasingly being performed. Additionally, there are several devices under investigation for implantation in a native annulus. Paravalvular leak (PVL) is a known complication of surgical or transcatheter valve implantation, where regurgitant flow occurs between the prosthetic sewing ring and the native mitral annulus. We sought to describe the role and applications of multimodality cardiac imaging for TMVR, and PVL closure, including the use of Cardiovascular Computed Tomography Angiography and 3-Dimensional Transesophageal Echocardiography for diagnosis, prosthetic valve evaluation, pre-procedural planning, and intraprocedural guidance, as well as evolving technologies such as fusion imaging and 3D printing.

Transcatheter para mitral annular ring leak device closure - A case report.

Project description:Para mitral annular ring leakage can occur following ring dehiscence after mitral annuloplasty. Percutaneous device closure of para-annular ring leakage can be performed successfully to treat such regurgitations with good transesophageal echocardiography guidance and patient selection. While para valvular device closure has been described in the medical literature, there have been few anecdotal reports published on para ring leak device closures. In this case, we highlight our experience from the successful closure of a para mitral annular ring closure with an AVP III device. The patient had a para annular ring regurgitation post coronary artery bypass grafting with mitral ring annuloplasty presenting with hemolytic anemia and acute renal failure, successfully treated by percutaneous device closure.Learning objectiveThis report describes the safety and effectiveness of a transcatheter para ring leak closure with an AVP III device. We applied the principles of device closure of paravalvular leak from our experience and related data from literature for this case and describe various hardware and techniques used for a successful closure of a para mitral ring leak.

Structures on the ventricular side of the prosthetic valve in extremely late mitral paravalvular leak: a case report.

Project description:BackgroundMechanisms of paravalvular leak (PVL) after mitral valve replacement have not been fully delineated. Herein, we report a case of structures on the ventricular side of the mitral valve in a patient with an extremely late PVL.Case summaryA 68-year-old female underwent aortic and mitral valve replacement with a mechanical valve 29 years ago. She was in good health for 28 years. However, exertional dyspnoea appeared 8 months ago. She was admitted to our hospital for congestive heart failure and haemolytic anaemia. Echocardiography showed severe regurgitation due to PVL of the mitral valve. The fluoroscopy showed that a circular calcification was found below the mitral prosthesis. The operation was performed through a median sternotomy. After the aortic cross-clamp, the aortic mechanical valve was removed. The ventricular side of the mitral valve was inspected with the endoscope through the aortic annulus before manoeuvers were performed in the mitral valve. A gap was seen between the prosthetic valve and annular tissue and subvalvular calcification. A bioprosthetic valve was placed with a modified collar-reinforcement technique using a xenopericardium strip. The postoperative course was uneventful. PVL and haemolysis completely disappeared.DiscussionThe ventricular side of the prosthetic valve could be observed before the mitral valve was removed. Not only the protruding circular calcification and displacement of the prosthetic valve to the atrial side but also the loss of adhesion and adhesive nature of the annular tissue played a definitive role in the late PVL occurrence and recurrence after percutaneous or surgical repair.
