Impact of a Successful Percutaneous Mitral Paravalvular Leak Closure on Long-term Major Clinical Outcomes. Can J Cardiol 2023:S0828-282X(23)01952-9. [PMID: 38013065 DOI: 10.1016/j.cjca.2023.11.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 11/13/2023] [Accepted: 11/21/2023] [Indexed: 11/29/2023] Open
Abstract
BACKGROUND Percutaneous mitral paravalvular leak (PVL) closure techniques are an effective and safe alternative to surgical treatment, but data regarding long-term outcomes are scarce. We aim to describe the impact of successful percutaneous mitral PVL closure on long-term outcomes. METHODS All consecutive patients in whom a first-attempt percutaneous mitral PVL closure was performed in a single tertiary centre between January 2010 and October 2021 were included. Clinical variables, procedural details, and procedural success were collected. Patients were classified based on procedural success, defined as no more than mild residual leak. All-cause mortality was the primary endpoint. Cardiovascular death and heart failure hospitalizations (HFHs) were key secondary endpoints. RESULTS Ninety patients (median age 72.5 years [66.0-78.4]; median EuroSCORE-II 8.2 [5.3-12.46]) were included. Although reduction of at least 1 degree in PVL severity was achieved in 82 (91.1%), procedural success was achieved in 47 (52.2%). Chronic kidney disease, previous surgery for PVL, and the presence of multiple jets were independently associated with procedural failure. After a median follow-up of 3.2 (1.2-5.2) years, mortality rate was higher in the procedural failure group (27.3 per 100 patients-years) compared with the group with successful closure (8.2 per 100 patient-years). Procedural failure was associated with all-cause death (adjusted hazard ratio [aHR], 2.59; 95% confidence interval [CI], 1.41-4.78), cardiovascular death (aHR, 3.53; 95% CI, 1.67-7.49) and HFH (aHR, 3.27; 95% CI,1.72-6.20). CONCLUSIONS A successful reduction in PVL to mild or absent is associated with improved rates of all-cause death, cardiovascular death, and HFHs.

Abstract
BACKGROUND Paravalvular leaks can be detected in almost 15% of patients after mitral valve prosthesis implantation. This complication can result in congestive heart failure and hemolysis. Despite advancements in non-invasive imaging, percutaneous closure of paravalvular leaks is not always successful. Therefore, efforts are made to improve treatment outcomes by using 3D-printed models of defects as pre-procedural support for interventional cardiologists. METHODS Retrospectively, 3D-transesophageal echocardiography recordings of 8 patients with clinically significant mitral paravalvular leaks were analyzed. Qlab Software was used to export DICOM images of each paravalvular leak channel, including surrounding tissue. Image segmentation was performed in 3D Slicer, a free, open-source software package used for imaging research. Models were printed to actual size with the poly jet Stratasys Objet 30 printer with a transparent, rigid material. RESULTS Duration of model preparation and printing, as well as the total cost, was calculated. Mean total time of model preparation was 430.5 ± 196 minutes. CONCLUSION 3D-printing from 3D-transesophageal echocardiography is technically feasible. Both shape and location of paravalvular leaks are preserved during model preparation and printing. It remains to be tested if 3D-printing would improve outcomes of percutaneous paravalvular leaks closure.

Abstract
Introduction Transcatheter closure of paravalvular leak (PVL) is still a demanding procedure due to the complex anatomy of PVL channels and risk of interference between the implanted occluder and surrounding structures. Efforts are made to improve procedural outcomes in transcatheter structural heart interventions by establishing treatment strategy in advance with the use of 3D-printed physical models based on data obtained from cardiac computed tomography (CT) studies. Aim In this feasibility study 3D printing of PVL models based on data recorded during transesophageal echocardiography (TEE) examinations was evaluated. Material and methods 3D-TEE data of patients with significant PVL around mitral valve prostheses were used to prepare 3D models. QLab software was used to export DICOM images in Cartesian DICOM format of each PVL with the surrounding tissue. Image segmentation was performed in Slicer, a free, open-source software package used for imaging research. Models were printed to actual size with the Polyjet printer with a transparent, rigid material. We measured dimensions of PVLs both in TEE recordings and printed 3D models. The results were correlated with sizes of occluding devices used to close the defects. Results In 7 out of 8 patients, there was concordance between procedurally implanted occluders and pre-procedurally matched closing devices based on 3D-printed models. Conclusions 3D-printing from 3D-TEE is technically feasible. Both shape and location of PVLs are preserved during model preparation and printing. It remains to be tested whether 3D printing would improve outcomes of percutaneous PVL closure.

Abstract
BACKGROUND Transcatheter closure of a symptomatic prosthetic paravalvular leak (PVL) is feasible, but there is presently no conclusive evidence to show consistent efficacy. We aimed to identify predictors of clinical success after transcatheter PVL closure. METHODS Consecutive patients referred to 24 European centers for transcatheter PVL closure in 2017 to 2019 were included in a prospective registry (Fermeture de Fuite ParaProthétique, FFPP). Clinical success was absence of any of the following within 1 month: re-admission for heart failure, blood transfusion, open-heart valvular surgery, and death. RESULTS We included 216 symptomatic patients, who underwent 238 percutaneous PVL closure procedures on the mitral (64.3%), aortic (34.0%), or tricuspid (1.7%) valve. Symptoms were heart failure, hemolytic anemia, or both in 48.9%, 7.8%, and 43.3% of patients, respectively. One, 2, and 3 leaks were treated during the same procedure in 69.6%, 26.6%, and 3.8% of patients, respectively. The PVL was pinpoint or involved 1/8 or 1/4 of the valve circumference in 18.6%, 52.4%, and 28.1% of cases, respectively. The most frequently used devices were the Vascular Plug 3, Ventricular Septal Defect Occluder, Vascular Plug 2, and Paravalvular Leak Device (45.0%, 16.6%, 14.2%, and 13.6% of cases, respectively). Successful device(s) implantation with leak reduction to ≤grade 2 was obtained in 85.0% of mitral and 91.4% of aortic procedures, respectively (P=0.164); with major periprocedural adverse event rates of 3.3% and 1.2%, respectively (P=0.371); and clinical success rates of 70.3% and 88.0%, respectively (P=0.004). By multivariate analysis, technical failure, mechanical valve, and hemolytic anemia were independently associated with absence of clinical success (odds ratios [95% CIs], 7.7 [2.0-25.0]; P=0.002; 3.6 [1.1-11.1]; P=0.036; and 3.7 [1.2-11.9]; P=0.025; respectively). CONCLUSIONS Transcatheter PVL closure is efficient and safe in symptomatic patients but is associated with a lower clinical success rate in patients with hemolysis and/or a mechanical valve.

Parameters of Flow through Paravalvular Leak Channels from Computational Fluid Dynamics Simulations—Data from Real-Life Cases and Comparison with a Simplified Model. J Clin Med 2022; 11:jcm11185355. [PMID: 36143002 PMCID: PMC9506366 DOI: 10.3390/jcm11185355] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 09/07/2022] [Accepted: 09/08/2022] [Indexed: 11/17/2022] Open
Abstract
Background: Shear forces affecting erythrocytes in PVL channels can be calculated with computational fluid dynamics (CFD). The presence of PVLs is always associated with some degree of hemolysis in a simplified model of the left ventricle (LV); however, data from real-life examples is lacking. Methods: Blood flow through PVL channels was assessed in two variants. Firstly, a PVL channel, extracted from cardiac computed tomography (CCT), was placed in a simplified model of the LV. Secondly, a real-life model of the LV was created based on CCT data from a subject with a PVL. The following variables were assessed: wall shear stress (τw) shear stress in fluid (τ), volume of PVL channel with wall shear stress above 300 Pa (V300), duration of exposure of erythrocytes to shear stress above 300 Pa (Vt300) and compared with lactate dehydrogenase (LDH) activity levels. Results: τw and τ were higher in the simplified model. V300 and Vt300 were almost identical in both models. Conclusions: Parameters that describe blood flow through PVL channels can be reliably assessed in a simplified model. LDH levels in subjects with PVLs may be related to V300 and Vt300. Length and location of PVL channels may contribute to a risk of hemolysis in mitral PVLs.

Quality of life after percutaneous paravalvular leak closure - a prospective registry. Adv Cardiol 2022; 18:261-268.

Abstract
Introduction Presence of paravalvular leaks (PVLs) can lead to heart failure, which decreases quality of life (QoL). Percutaneous closure is becoming the first-line treatment of PVLs, but whether such a procedure could improve QoL in these patients has never been examined. Aim To examine changes in scores of the Minnesota Living with Heart Failure Questionnaire (MLHFQ) and Kansas City Cardiomyopathy Questionnaire (KCCQ) after percutaneous PVL closure. Material and methods Forty subjects with heart failure symptoms and at least moderate PVL were included in this prospective registry. QoL was assessed at baseline and during a 12-month follow-up after percutaneous PVL closure by MLHFQ and KCCQ questionnaires. Changes in NT-proBNP and lactate dehydrogenase (LDH) levels were also analyzed. Results Technical success (TS) was achieved in 97.5% of cases and procedural success (PS) in 85% of cases. In the group with PS a significant decrease in MLHFQ score as well as an increase in scores of all KCCQ domains was observed. No statistically significant changes were observed in the group without PS, mainly due to the small sample size. Conclusions Percutaneous PVL closure is associated with better QoL during a 12-month follow-up provided PS was achieved. Due to the low number of subjects in whom PS was not achieved, it is not possible to determine the influence of a failed procedure in this group of patients.

Abstract
Percutaneous device closure has become a valuable alternative to surgery in the management of paravalvular leaks. Consequently, imaging in these patients is currently not only meant to verify the hemodynamic significance of the lesion but also to assess the feasibility of transcatheter treatment. We present a methodology of comprehensive echocardiography assessment that allows for the selection of patients and plans the intervention. Next, procedure-oriented steps of echocardiography imaging, which are essential for eventual success, are reviewed.

Abstract
In recent years, computational fluid dynamics (CFD) has been extensively used in biomedical research on heart diseases due to its non-invasiveness and relative ease of use in predicting flow patterns inside the cardiovascular system. In this study, a modeling approach involving CFD simulations was employed to study hemodynamics inside the left ventricle (LV) of a human heart affected by a mitral paravalvular leak (PVL). A simplified LV geometry with four PVL variants that varied in shape and size was studied. Predicted blood flow parameters, mainly velocity and shear stress distributions, were used as indicators of how presence of PVLs correlates with risk and severity of hemolysis. The calculations performed in the study showed a high risk of hemolysis in all analyzed cases, with the maximum shear stress values considerably exceeding the safe level of 300 Pa. Results of our study indicated that there was no simple relationship between PVL geometry and the risk of hemolysis. Two factors that potentially played a role in hemolysis severity, namely erythrocyte exposure time and the volume of fluid in which shear stress exceeded a critical value, were not directly proportional to any of the characteristic geometrical parameters (shape, diameters, circumference, area, volume) of the PVL channel. Potential limitations of the proposed simplified approach of flow analysis are discussed, and possible modifications to increase the accuracy and plausibility of the results are presented.

Janmohamed IK, Mishra V, Geragotellis A, Sherif M, Harky A. Mitral valve paravalvular leaks: Comprehensive review of literature. J Card Surg 2021; 37:418-430. [PMID: 34822197 DOI: 10.1111/jocs.16145] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 10/13/2021] [Accepted: 10/29/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND Mitral paravalvular leaks (mPVL) are a recognized complication for patients with mitral valve prostheses. Although clinically insignificant for many patients, it may pose life-threatening haemolysis and regurgitation-induced heart failure, and so clinicians should have a high index of suspicion in the presence of new symptoms. AIMS This review discusses the pathogenesis, clinical features, diagnosis, imaging and treatment of mPVLs. METHODS A comprehensive literature search was performed using PubMed, EMBASE, Cochrane database, Google Scholar and Ovid. Search terms used included "mitral valve paravalvular leak," "transthoracic echocardiography," "2D transoesophageal echocardiography," "3D transoesophageal echocardiography," "cardiac computed tomography," (CT) "cardiac magnetic resonance imaging," "intracardiac echocardiography," "cinefluoroscopy," "fluoroscopy," and "percutaneous closure." RESULTS All patients with mPVLs should undergo regular full evaluation, including patient history, physical examination, laboratory work-up, imaging, and referral, if necessary. Echocardiography is fundamental to the diagnosis, and is augmented with cardiac magnetic resonance imaging, cardiac computerized tomography and fluoroscopy for further characterization and procedural planning amongst the structural heart team. CONCLUSION The prevalence of mPVL is expected to increase proportionally to the growing number of surgical and transcatheter valve replacements conducted in the ageing population. Multimodal imaging is instrumental in guiding diagnostic and therapeutic strategies when managing mPVLs. Advances in imaging and capabilities of transcather devices will prompt growing uptake of percutaneous treatment over conventional, higher-risk surgery for mPVL management.

Abstract
Mitral regurgitation (MR) is one of the most frequently encountered types of valvular heart disease in the United States. Patients with significant MR (moderate-to-severe or severe) undergoing noncardiac surgery have an increased risk of perioperative cardiovascular complications. MR can arise from a diverse array of causes that fall into 2 broad categories: primary (diseases intrinsic to the valvular apparatus) and secondary (diseases that disrupt normal valve function via effects on the left ventricle or mitral annulus). This article highlights key guideline updates from the American College of Cardiologists (ACC) and the American Heart Association (AHA) that inform decision-making for the anesthesiologist caring for a patient with MR undergoing noncardiac surgery. The pathophysiology and natural history of acute and chronic MR, staging of chronic primary and secondary MR, and considerations for timing of valvular corrective surgery are reviewed. These topics are then applied to a discussion of anesthetic management, including preoperative risk evaluation, anesthetic selection, hemodynamic goals, and intraoperative monitoring of the noncardiac surgical patient with MR.

Abstract
Transcatheter mitral valve implantation is an emerging technology for the treatment of inoperable or high-risk patients with symptomatic severe mitral regurgitation. Known technical issues are obstruction of the left ventricular outflow tract, paravalvular leakage, and hemolysis. We report a case of valve retensioning successfully resolving paravalvular leakage and hemolysis. (Level of Difficulty: Intermediate.).

Structural and Functional Characteristics of Mitral Paravalvular Leakage Identified by Multimodal Imaging and Their Implication on Clinical Presentation. J Clin Med 2021; 10:jcm10020222. [PMID: 33435160 PMCID: PMC7826927 DOI: 10.3390/jcm10020222] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2020] [Revised: 12/27/2020] [Accepted: 01/07/2021] [Indexed: 12/28/2022] Open
Abstract
OBJECTIVE Clinical presentation of patients with mitral paravalvular leakage (PVL) varies from asymptomatic to heart failure related with hemolytic anemia or pulmonary hypertension. We aimed to investigate the structural and functional characteristics of mitral PVL by multimodal imaging and their association with the severity of hemolysis and hemodynamic significance. METHODS A total of 74 patients with mitral PVL who underwent both cardiac computed tomography (CT) and echocardiography from March 2010 to December 2017 was investigated. Location and size of PVL, degree of left atrial (LA) calcification as measured by CT, and hemodynamic variables as measured by echocardiography were comprehensively analyzed. To investigate the degree of hemolysis and pulmonary hypertension, level of lactate dehydrogenase (LDH) and Doppler estimated systolic pulmonary artery pressure (SPAP) were used respectively. RESULTS Level of LDH was not related to PVL perimeter and was variable, especially in patients with a small PVL. However, it was positively correlated with mean mitral regurgitation velocity. Additionally, SPAP was significantly correlated with PVL perimeter and LA calcium score. In multivariable analysis, mean mitral regurgitation velocity was significantly correlated with levels of LDH (β = 0.345; p = 0.016), and PVL perimeter and LA calcium score were independently associated with SPAP (β = 0.249; p = 0.036 and β = 0.467; p < 0.001, respectively). CONCLUSIONS Characteristics of mitral PVL and adjacent structures are associated with the severity of hemolysis and pulmonary hypertension. Evaluating the structural and functional characteristics of mitral PVL by complementary multimodal imaging would be important for understanding the clinical presentation and deciding optimal treatments for individual patients.

EUROPEAN HEART JOURNAL-CASE REPORTS 2020; 4:1-6. [PMID: 33073168 PMCID: PMC7543880 DOI: 10.1093/ehjcr/ytaa101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/01/2019] [Revised: 05/20/2019] [Accepted: 04/01/2020] [Indexed: 11/12/2022]
Abstract
Background Haemolytic 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 summary We 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). Discussion Mild residual paravalvular leak can cause severe haemolytic anaemia that is correctable via percutaneous closure of the leak.

Abstract
PURPOSE OF REVIEW With increasing use of prosthetic valves to treat degenerative valvular heart disease (VHD) in an aging population, the incidence and adverse consequences of paravalvular leaks (PVL) are better recognized. The present work aims to provide a cohesive review of the available literature in order to better guide the evaluation and management of PVL. RECENT FINDINGS Despite gains in operator experience and design innovation, significant PVL remains a significant complication that may present with congestive heart failure and/or hemolytic anemia. To date, clear consensus or guidelines on the evaluation and management of PVL remain lacking. Although the evolution of transcatheter valve therapies has had a tremendous impact on the management of patients with VHD, the limitations and complications of such techniques, including PVL, present further challenges. Incidence of PVL, graded as moderate or greater, ranges from 4 to 7.4% in surgical and transcatheter valve replacements, respectively. Improved imaging modalities and the advent of novel surgical and percutaneous therapies have undoubtedly yielded a better understanding of PVL including its anatomical location, mechanism, severity, and treatment options. Echocardiography, used in conjunction with cardiac computed tomography and cardiac magnetic resonance, provides essential details for diagnosis and management of PVL. Transcatheter intervention has become a favored approach in lieu of surgical intervention in select patients after previous surgical or percutaneous valve replacement. PVL treatment with vascular plugs, balloon post-dilation, and the valve-in-valve methods have shown technical success with promising clinical outcomes in appropriately selected patients.

Abstract
Introduction Transcatheter paravalvular leak closure (TPVLC) has become a well-established method of treatment for patients with paravalvular leak (PVL) causing heart failure or significant hemolysis. Nonetheless, the method of optimal PVL sizing and subsequent device choice requires standardization. For this purpose a real-time three-dimensional transesophageal echocardiography (RT-3D TEE) algorithm was developed in our institution. It has proven clinically useful with results successfully translated into type, size, and number of occluding devices. Still, the reproducibility of measurements has not been previously verified. Aim To investigate the intra- and inter-observer variability of measurements in a RT-3D TEE algorithm developed for optimal choice of occluding devices during TPVLC. Material and methods Three echocardiographers, with RT-3D TEE clinical experience ranging from 1 to 8 years, analyzed recordings of 20 mitral PVLs according to our standardized protocol. PVL channel cross-sectional area (CSA), width (W) and length (L) were measured at the level of the vena contracta. Each echocardiographer performed the measurements twice on different days, individually and blinded to other participants’ results. Results Measurements of PVL CSA, W and L showed intra- and interobserver agreement of 0.98, 0.93, 0.92 and 0.95, 0.88, 0.87, respectively. Conclusions The presented algorithm enables standardized utilization of RT-3D TEE for appropriate TPVLC device choice with low intra- and inter-observer variability.

Abstract
Hemolysis is an unintended sequel of temporary or permanent intracardiac devices. However, limited data exist on the characteristics and treatment of hemolysis in patients with cardiac prostheses. This entity, albeit uncommon, often poses significant diagnostic and management challenges to the clinical cardiologist. In this article, we aim to provide a contemporary overview of the incidence, mechanisms, diagnosis, and management of cardiac prosthesis‐related hemolysis.

Abstract
Introduction Due to the recent lack of definitions to establish the severity of paravalvular leak (PVL) and endpoints for its treatment, the effectiveness and safety of a new device for PVL closure have not been comprehensively analyzed. Aim To analyze a single center’s experience of mitral PVL closure in a surgical transapical catheter-based fashion with a purpose-specific device. Material and methods This is a retrospective cohort study of patients following transapical catheter-based mitral PVL closure with a purpose-specific device. Data were analyzed at baseline, perioperatively, at discharge, at six months and annually after the procedure. Results Nineteen patients underwent surgical transapical catheter-based mitral PVL closure with the Occlutech PLD Occluder. Mean follow-up time was 20 ±7 (range: 9–33) months. The patients’ mean age was 64 ±7 years, and 11 (58%) were male. Technical, device and individual patient success at follow-up was achieved in 18 (95%), 16 (84%) and 16 (84%) patients respectively. Median intensive therapy unit stay was one day (1–4) and mean hospital stay was 11 ±4 days. A reduction of paravalvular regurgitation to a mild or lesser degree was achieved in 18 (95%) patients. There were no strokes or myocardial infarctions at follow-up. There were no deaths at 30 days after the procedure. One (5%) patient expired due to progression of heart failure 12 months after surgery. None of the patients required immediate conversion to full sternotomy. Conclusions Surgical transapical catheter-based mitral PVL closure with the Occlutech PLD Occluder is a safe and clinically effective treatment.
