Comparison of Pericardial and Prosthetic Rings for Mitral Repair: Are Pericardial Rings Durable in the Mid- to Long-Term Follow Up?

While prosthetic rings are commonly used for mitral valve repairs, autologous pericardium is an alternative ring material that can be used in these procedures. In this report, we aim to present a comparison of two types of rings used for mitral repair. Between January 2005 and January 2009, 107 patients who underwent mitral valve repair surgery were analyzed. Patients were divided into two groups, according to the type of ring that was used for mitral annular stabilization. Glutaraldehyde-treated pericardial rings were used for 31 patients (group 1), whereas prosthetic rings were used for 76 patients (group 2). Survival, freedom from reoperation, recurrent mitral regurgitation, and the effects of rheumatic mitral disease on these parameters were evaluated and compared for both groups. Follow-up time for our cohort was 4.24±0.4 years. There were four and seven late mortalities in groups 1 and 2, respectively, and five reoperations in each group. There was no significant difference between the groups, in terms of survival, freedom from reoperation, and recurrent mitral regurgitation (log-rank analyses for both groups were P = 0.777, P = 0.346, and P = 0.781, respectively). There was no significant difference in freedom from reoperation and recurrent mitral regurgitation for both groups, in terms of underlying rheumatic valvular disease and other types of pathology. Pericardial ring annuloplasty shows to be a considerable alternative technique for mitral valve repair procedures in the mid- to long-term follow up. Rheumatic mitral valves had poor outcomes, when compared with other types of structural valvular pathologies in cases where pericardial rings were used in the repair procedure.

Aortic valve repair in the pediatric population: emerging role of aortic valve neocuspidization (AVNeo procedure).

Management of aortic valve diseases in children is challenging owing to the quality and quantity of the native tissue for repair, limitations in the currently available biological materials to supplement the repair and to achieve a long-lasting durable repair in an annulus where there is still growth potential. The aortic valve neocuspidization (AVNeo) procedure has emerged as a versatile alternative strategy in the armamentarium of pediatric aortic valve reconstructions that are currently available. In this review article, the focus of the discussion will be on the various aortic valve repair procedures in the pediatric population, with a special emphasis on the emerging role of AVNeo procedure in pediatrics and its outcomes.

Takotsubo cardiomyopathy after cardiac surgery: A case-series and systematic review of literature.

Takotsubo cardiomyopathy (TTC) is a rare entity after cardiac surgery. To describe patients' profile who developed postoperative TTC after cardiac surgery, management, and outcomes. We performed a systematic literature search to extract cases of TTC after adult cardiac surgery (from 1990 to 2021). Additionally, we extracted all cases of TTC in a prospective single-center cohort database of 10,000+ patients (from 2007 to 2019). We then combined all cases in a single cohort to describe its clinical features. From 694 screened articles, we retained 71 individual cases published in 20 distinct articles (19 cases reports and 1 case-series). We combined these to 10 cases extracted from our cohort [among 10,682 patients (0.09%)]. Overall, we included 81 cases. Patients were aged 68 ± 10 years-old and 64/81 (79%) were women. Surgery procedures included mitral valve and/or tricuspid valve surgery in 70/81, 86%. TTC was diagnosed in the first days after surgery [median 4 (1-4) days]. Incidence of cardiogenic shock, defined as requirement of vasopressor and/or inotropic support was 24/29, 83% (data available on 29/81 patients). Refractory cardiogenic appeared in 5/81, 6% who required implantation of arterio-venous extra-corporeal membrane oxygenation, and 6/81, 7%, intra-aortic balloon pump. In-hospital mortality was 5/81, 6%. This systematic review, based on case reports and case series, showed that postoperative TTC appears as a rare complication after cardiac surgery and mainly occurred after mitral and/or tricuspid valve repair procedures. In this population, TTC is associated with high rate of cardiogenic shock.

Mitral valve repair and concomitant maze procedure versus catheter ablation in the treatment of atrial functional mitral regurgitation

BackgroundTo compare mitral valve (MV) repair and concomitant maze procedure with catheter ablation in treating patients with atrial functional mitral regurgitation (AFMR).MethodsWe retrospectively identified 126 patients with AFMR from January 2012 to December 2015. Of these patients, 60 patients underwent MV repair and concomitant maze procedure, and 66 patients received catheter ablation. Patients were followed up for 7.98 ± 2.01 years. The survival, readmission of heart failure (HF), persistent atrial fibrillation (AF), persistent moderate-severe mitral regurgitation (MR) and tricuspid Regurgitation (TR), and echocardiographic data were analyzed in the follow-up. Predictors of readmission of HF were analyzed.ResultsThere was no significant difference in baseline and echocardiographic characteristics, in-hospital mortality, and other adverse events postoperatively between two groups. The surgical group was associated with lower rates of MR > 2 + grade either at discharge (P = 0.0023) or in the follow-up (P = 0.0001). There was no significant difference in the incidence of overall survival between the two groups. The surgical group was associated with a lower rate of readmission of HF and AF in the follow-up. Univariable and multivariable analysis confirmed AF at discharge, moderate-severe MR at discharge, no MV surgery, moderate-severe TR at discharge, and LA volume as predictors of readmission of HF. Both groups experienced significant reverse cardiac remodeling.ConclusionsOur results suggest that for the treatment of AFMR with persistent or long-standing persistent AF and moderate-severe MR, MV repair and concomitant maze procedure may achieve a better outcome than catheter ablation procedure.

Quantitative invivo assessment of human mitral valve coaptation area after undersized ring annuloplasty repair for ischemic mitral regurgitation.

Long-term outcomes of mitral valve repair procedures to correct ischemic mitral regurgitation remain unpredictable, due to an incomplete understanding of the disease process and the inability to reliably quantify the coaptation zone using echocardiography. Our objective was to quantify patient-specific mitral valve coaptation behavior from clinical echocardiographic images obtained before and after repair to assess coaptation restoration and its relationship with long-term repair durability. To circumvent the limitations of clinical imaging, we applied a simulation-based shape-matching technique that allowed high-fidelity reconstructions of the complete mitral valve in the systolic configuration. We then applied this method to an extant database of human regurgitant mitral valves before and after undersized ring annuloplasty to quantify the effect of the repair on mitral valve coaptation geometry. Our method was able to successfully resolve the coaptation zone into distinct contacting and redundant regions. Results indicated that in patients whose regurgitation recurred 6months postrepair, both the contacting and redundant regions were larger immediately postrepair compared with patients with no recurrence (P<.05), even when normalized to account for generally larger recurrent valves. Although increasing leaflet coaptation area is an intuitively obvious way to improve long-term repair durability, this study has implied that this may not be a reliable target for mitral valve repair. This study underscores the importance of a rigorous understanding of the consequences of repair techniques on mitral valve behavior, as well as a patient-specific approach to ischemic mitral regurgitation treatment within the context of mitral valve and left ventricle function.

Abstract 14109: Safety and Effectiveness of Trans-Catheter Tricuspid Valve Repair in the Elderly and Very Elderly Patients

Introduction: Symptomatic tricuspid regurgitation (TR) is associated with a high mortality rate and high HF-related hospitalization. Symptomatic therapy in the elderly and very elderly patients remains weak in controlling severe TR. Patients with an increased risk of surgical repair of the TR seemed to benefit from transcatheter tricuspid valve repair procedures. Hypothesis: Therefore, we thought to analyze the postprocedural safety and success of the transcatheter tricuspid valve repair in octogenarians and older patients. Methods: Elderly patients with severe and symptomatic TR were presented and evaluated in the heart team. Patients with high surgical risks underwent transcatheter tricuspid valve repair procedures in our center. Post-procedural transthoracic echocardiography (TTE) procedure was performed to determine the TR grade and exclude procedure-related complications. Results: Thirty-three consecutive patients, older than 80 years (84.45 ±3.12, 14 men and 19 women, who received transcatheter TR repair between September 2021 and January 2022 were enrolled. The baseline characteristics are presented in table 1. Procedural success, defined as reducing the TR to grad I-II, was achieved in 97 % of the patients (3.79±0.65 vs. 1.55±0.56, P = 0.011). All patients improved in the New York Heart Association functional class (2.85±0.50 vs. 1.39±0.056 30 days after the intervention). No procedure-related death was registered. 87.9 % (n=29) survival rate was achieved 3 months after the intervention. No clip embolization was detected in 3 months echocardiography control. Conclusions: Our preliminary results indicate that transcatheter tricuspid valve repair procedures are safe and effective therapeutic option in elderly and very elderly patients with severe TR and high surgical risks. Therefore, this therapy should be considered despite age and comorbidities for effective symptomatic treatment in this cohort.

Minimally Invasive Beating Heart Mitral Valve Repair in a Patient With Connective Tissue Disease at Prohibitive Risk for Redo Sternotomy

Sternal reentry when the ascending aorta is adherent to the posterior table of the sternum is associated with substantial risk. A minimally invasive right thoracotomy beating heart approach is an alternative when the aorta cannot be cross-clamped. This report details this technique for a complex reoperative mitral valve repair procedure performed in a patient with connective tissue disease who had required multiple aortic operations and presented with heart failure and severe functional mitral regurgitation.

Robotic mitral valve repair in National Taiwan University Hospital: 10-year results.

With the help of robotic surgical systems and their 3-dimensional, high-resolution imaging, mitral repair with long shaft instruments and endo-wrist functionality has become a feasible reality. Patients benefit from maintained thoracic cage integrity, reduced surgical trauma, and faster return to normal functional activity. We describe National Taiwan University Hospital's 10-year experience with robotic-assisted mitral valve repair procedures for repairing mitral regurgitation. We performed a retrospective observational cohort study of patients undergoing robotic-assisted mitral valve repair for severe mitral regurgitation at National Taiwan University Hospital. Between January 2012 and September 2022, 450 consecutive patients underwent robotic mitral valve repair with or without additional cardiac procedures. All procedures were completed by a single surgical team. Four hundred and fifty patients, with 272 (60.4%) isolated mitral repairs and 178 (39.6%) combined additional (one or more) cardiac procedures were performed. The Euroscore II estimate mortality was 3.1%±2.7%. The average cardiopulmonary bypass (CPB) time was 124±42 minutes, and the average operation time was 165±51 minutes. Perioperative and 30-day mortality was observed in one (0.22%) patient. Mean intensive care unit stay was 26.5±26.0 hours. Postoperative stroke was observed in one (0.22%) patient and new-onset atrial fibrillation was observed in 71 (15.78%) patients. All patients were in less than mild mitral regurgitation and 422 (93.78%) had none or trace regurgitation at discharge. Freedom from moderate mitral regurgitation was 97.6%, and freedom from mitral valve reoperation was 98% at 10 years. With standardized robotic procedures and non-compromised repair techniques, excellent short-term outcomes and long-term valve repair durability can be achieved in experienced centers.

Thoracic Interfascial Plane Blocks and Outcomes After Minithoracotomy for Valve Surgery.

Introduction. Thoracic interfascial plane blocks are increasingly used for pain management after minimally invasive thoracotomy for valve repair and replacement procedures. We hypothesized that the addition of these blocks to the intercostal nerve block injected by the surgeon would further reduce pain scores and opioid utilization. Methods. In this retrospective cohort study, 400 consecutive patients who underwent minimally invasive thoracotomy for mitral or aortic valve replacement and were extubated within 2hours of surgery were enrolled. The maximum pain score and opioid utilization on the day of surgery and other outcome variables were compared between patients who received interfascial plane blocks and those who did not. Results.193 (48%) received at least one interfascial plane block while 207 (52%) received no interfascial plane block. Patients who received a thoracic interfascial plane block had a maximum VAS score on the day of surgery (mean 7.4 ± 2.5) after the block was administered which was significantly lower than patients in the control group who did not receive the block (mean 7.9 ± 2.2) (P = .02). Opioid consumption in the interfascial plane block group on the day of surgery was not significantly different from the control group. Conclusion. Compared to intercostal blocks alone, the addition of thoracic interfascial plane blocks was associated with a modest reduction in maximum VAS score on the day of surgery. However, no difference in opioid consumption was noted. Patients who received interfascial plane blocks also had decreased blood transfusion requirements and a shorter hospital length of stay.

Impact of atrial fibrillation on outcome of percutaneous mitral valve repair (PMVR) procedure

Abstract Background Limited evidence exists regarding the impact of atrial fibrillation (AF) on outcomes after percutaneous mitral valve repair (PMVR). The aim of the present study was to compare 1-year clinical outcomes following PMVR in patients with and without AF. Methods 426 patients with PMVR for severe MR were included in the COburg MItraclip (COMI) registry between 2016 and 2021. Patients were divided into an AF group (group A, n=284) and a non-AF group (group B, n=142). Clinical profiles, PMVR procedure characteristics and the clinical follow-up were compared between the two groups. Results Patients with AF were older (79.3±6.3 [AF] vs. 77.8±8 years [non-AF], p=0.03), had higher N-terminal B-type natriuretic peptide levels (NT-pro BNP: 5675±5544.2 vs 8516±11184.5, p=0.004), more often a coronary artery disease (62% vs 38%, p=0.03) and had a lower stroke risk (CHA2DS2-VASc score: 4.6±1.2 vs 4.9±1.3, p=0.01). There were no significant differences between groups with regard to the gender, logistic Euroscore or prevalence of chronic heart failure, hypertension, diabetes mellitus or severe mitral regurgitation. Acute procedural success (post-procedural 2. MR, 95.1% vs. 94.4%; p=0.76) and procedure-related major complications were similar. There were no significant differences in 1-year MACCE (death, MI, stroke, bleeding), health-related quality of life or clinical improvement. Conclusion In patients with mitral regurgitation who underwent PMVR, AF is common and appears not to have a relevant negative impact on the clinical outcome at 1 year compared to patients with sinus rhythm.

Validation of expert criteria proposed by the “German Cardiac Society” for predicting procedural complexity in transcatheter edge-to-edge mitral valve repair

Abstract Background Following up on the original EVEREST criteria and several years of procedural experience, the German Cardiac Society (GCS) proposed refined criteria indicating morphological complexity in transcatheter edge-to-edge mitral valve repair (TEER) procedures which so far have not been validated. Methods In a retrospective analysis of transesophageal echocardiography images of consecutive patients undergoing TEER in two high-volume centres, complexity was classified according to GCS criteria as optimal (neither characteristics of “complex” nor “very complex', see Table 1), complex (any of the “complex” criteria but no “very complex” criteria) and very complex (any of the “very complex” criteria). Associations with the procedural outcome, reintervention, survival, and heart failure rehospitalization were tested. Results 633 patients (mean age 79 years, range 50 to 96 years, 59% male) were included, with 35% having dominant primary and 65% having dominant secondary mitral regurgitation (MR). 19% of patients were classified as having optimal, 40% as complex, and 41% as very complex morphologies. Successful clip implantation and reduction in MR ≤2 at discharge were achieved in 100% and 97% in the optimal, in 96% and 88% in the complex, and in 95% and 88% in the very complex morphologies, respectively (p for difference 0.13 and 0.42). The rate of successful clip deployment was significantly lower and the rate of reintervention significantly higher in patients with a mitral valve orifice area ≤3 cm2, compared to patients with a mitral valve orifice area &amp;gt;3 cm2. Pathology extent of MR likely requiring &amp;gt;2 clips was significantly associated with a lower rate of MR reduction to grade ≤2. Midterm (median follow-up time 640 days) mortality or hospitalization due to heart failure was significantly higher in patients with a posterior mitral leaflet length of 7–10 mm. Conclusion In the setting of experienced heart valve centres only a few of the complexity criteria proposed by the GCS impact on procedural and clinical outcomes. Even in the case of complex or very complex mitral valve morphology, TEER can be performed effectively with reduction of MR to ≤2 in 88% of cases.

Two hundred robotic mitral valve repair procedures for degenerative mitral regurgitation: the Yale experience.

BackgroundRobotic surgery has gained popularity over the past two decades due to the benefits related to smaller surgical incisions, enhanced technical dexterity and better intraoperative visualization. We present the Yale experience of the first two hundred totally endoscopic, robotic-assisted mitral valve repair procedures for the treatment of degenerative mitral regurgitation.MethodsWe performed a retrospective cohort study of patients undergoing totally endoscopic, robotic-assisted isolated or concomitant mitral valve repair for degenerative mitral regurgitation at Yale-New Haven Hospital from October 2018 to April 2022. Mitral valve repair procedures for rheumatic or secondary functional mitral regurgitation and planned robotic-assisted mitral valve replacement cases were excluded.ResultsTwo hundred consecutive procedures were performed. The median age was 65 years (interquartile range, 58–73 years). Six patients (3.0%) had a history of mediastinal radiation, four patients (2.0%) had previous cardiac surgery, and one patient (0.5%) had cardiac dextroversion. Median cardiopulmonary bypass and aortic cross-clamp times were 122 and 79 minutes, respectively. Femoral vessel cannulation was performed percutaneously in 57 (28.5%) patients with no major access-site related complication. Aortic cross-clamping was performed with the endoaortic balloon occlusion device in 151 (75.5%) patients. No conversions to sternotomy occurred. Satisfactory repair was achieved in 100% of cases, with 184 (92.0%) and 16 (8.0%) of patients having trace/none or mild residual mitral regurgitation, respectively. Forty-two patients (21.0%) underwent concomitant Cox-maze procedure and 25 patients (12.5%) underwent concomitant tricuspid valve repair. Thirty-day mortality rate was 0.5%, with an observed-to-expected ratio of 0.53. Two patients (1.0%) underwent re-exploration for bleeding, one had early postoperative stroke (0.5%), five developed pneumothorax (2.5%) and two required dialysis for acute renal failure (1.0%). The median length of hospital stay was four days.ConclusionsExcellent short-term outcomes can be achieved in experienced centers for the treatment of degenerative mitral regurgitation with a totally endoscopic, robotic-assisted approach.

Role of computed tomography in transcatheter replacement of ‘other valves’: a comprehensive review of preprocedural imaging

Transcatheter procedures for heart valve repair or replacement represent a valid alternative for treating patients who are inoperable or at a high risk for open-heart surgery. The transcatheter approach has become predominant over surgical intervention for aortic valve disease, but it is also increasingly utilized for diseases of the 'other valves', that is the mitral and, to a lesser extent, tricuspid and pulmonary valve. Preprocedural imaging is essential for planning the transcatheter intervention and computed tomography has become the main imaging modality by providing information that can guide the type of treatment and choice of device as well as predict outcome and prevent complications. In particular, preprocedural computed tomography is useful for providing anatomic details and simulating the effects of device implantation using 3D models. Transcatheter mitral valve replacement is indicated for the treatment of mitral regurgitation, either primary or secondary, and computed tomography is crucial for the success of the procedure. It allows evaluating the mitral valve apparatus, the surrounding structures and the left heart chambers, identifying the best access route and the landing zone and myocardial shelf, and predicting obstruction of the left ventricular outflow tract, which is the most frequent postprocedural complication. Tricuspid valve regurgitation with or without stenosis and pulmonary valve stenosis and regurgitation can also be treated using a transcatheter approach. Computer tomography provides information on the tricuspid and pulmonary valve apparatus, the structures that are spatially related to it and may be affected by the procedure, the right heart chambers and the right ventricular outflow tract.

Partial posterior leaflet resection for mitral valve endocarditis and valve repair with autologous pericardium

Herein, we present a 55-year-old female who underwent a mitral valve repair procedure for mitral valve endocarditis. Multiple vegetations and leaflet tissues were surgically removed from the P1 and P2 scallops. The defect of the posterior leaflet was repaired using autologous pericardium. Rims of the persicardium supported three artificial chordae to obtain good mitral coaptation. The postoperative course was uneventful. The patient was discharged on the 30th postoperative day.

Concomitant Mitral Valve Re-Repair for Mixed Congenital and Degenerative Mitral Disease, Tricuspid Repair, and Cox-Maze Procedure in a College Athlete.

A significant proportion of patients undergoing repair of congenital mitral valve disease will require a subsequent reoperation. During somatic growth, mitral valve repair is preferable to replacement as it allows for annular growth, preservation of ventricular function, and avoidance of lifelong anticoagulation. Techniques to facilitate successful re-repairs for congenital and non-rheumatic mixed degenerative mitral valve disease are not well-described in the literature. Description of the encountered pathology and surgical maneuvers utilized in this case provides real-world tools to help surgeons deal with limited orifice availability, fibrosis, and multilevel lesions. We describe a mitral valve re-repair in a young athlete for a rare cleft posterior mitral leaflet, with a simultaneous tricuspid valve repair and Cox-Maze procedure. We focus on technical pearls that address specific anatomic challenges within our surgical approach.

Lockdown surgery: the impact of coronavirus disease 2019 measures on cardiac cases.

OBJECTIVESThe need to ration medical equipment and interventions during the coronavirus disease 2019 pandemic translated to an ever-lengthening wait list for surgical care. Retrospective analysis of lockdowns is of high importance to learn from the current situation for future pandemics. This monocentric study assessed the impact of lockdown periods on cardiac surgery cases and outcomes.METHODSThe single-centre cross-sectional descriptive observational study was conducted to investigate the first lockdown period and the following post-lockdown period in comparison to the same periods during the previous 3 years at the Department of Cardiac Surgery at the Medical University of Innsbruck. Data were prospectively collected and retrospectively analysed from the department-specific quality management system. The primary objective was to compare the number of open-heart procedures between the prelockdown and the lockdown period. The secondary objectives were to analyse the characteristics and the outcomes of open-heart procedures.RESULTSThere were no differences in patient demographics. A significant decrease of 29% in weekly surgical procedures was observed during the lockdown period. The surgical case-mix was unaffected: The numbers of aortic valve replacements, coronary artery bypass grafts, mitral valve repair or replacement procedures and others remained stable. The urgency of cases increased significantly, and the general health conditions of patients appeared to be worse. However, outcomes were unchanged.CONCLUSIONSBy implementing a rational patient selection process, the quality of open-heart procedures was maintained even though patients who underwent surgery during lockdown were sicker and more symptomatic.

Predictors of Mortality Following Aortic Valve Replacement in Aortic Stenosis Patients.

Background: Understanding of the risk factors for the development of adverse outcomes after aortic valve replacement is necessary to develop timely preventive measures and to improve the results of surgical treatment. Methods: We analyzed patients with aortic stenosis (n = 742) who underwent surgical treatment in the period 2014–2020. The average age was 63 (57;69) years—men 58%, women 42%. Results: The hospital mortality rate was 3% (22 patients). The following statistically significant threshold values (cut-off points) were obtained in the ROC analysis: aortic cross-clamp time > 93 min AUC (CI) 0.676 (0.640–0.710), p = 0.010; cardiopulmonary bypass time > 144 min AUC (CI) 0.809 (0.778–0.837), p < 0.0001, hemoglobin before op <120 g/L. AUC (CI) 0.762 (0.728–0.793), p < 0.0001, hematocrit before op <39% AUC (CI) 0.755 (0.721–0.786), p < 0.001, end-diastolic dimension index >2.39 AUC (CI) 0.647 (0.607–0.686), p = 0.014, end-systolic dimension index > 1.68 AUC (CI) 0.657 (0.617–0.695), p = 0.009. Statistically significant independent predictors of hospital mortality were identified: BMI > 30 kg/m2 (OR 2.84; CI 1.15–7.01), ischemic heart disease (OR 3.65; CI 1.01–13.2), diabetes (OR 3.88; CI 1.38–10.9), frequent ventricular ectopy before operation (OR 9.78; CI 1.91–50.2), mitral valve repair (OR 4.47; CI 1.76–11.3), tricuspid valve repair (OR 3.06; CI 1.09–8.58), 3 and more procedures (OR 4.44; CI 1.67–11.8). Conclusions: The hospital mortality rate was 3%. The main indicators associated with the risk of death were: diabetes, overweight (body mass index more than 30 kg/m2), frequent ventricular ectopy before surgery, hemoglobin level below 120 g/L, hematocrit level below 39%, longer cardiopulmonary bypass time and aortic cross-clamp time, additional mitral and tricuspid valve interventions.

Using Position‐Based Dynamics for Simulating Mitral Valve Closure and Repair Procedures

AbstractTo achieve the best treatment of mitral valve disease in a patient, surgeons aim to optimally combine complementary surgical techniques. Image‐based in silico simulation as well as visualization of the mitral valve dynamics can support the visual analysis of the patient‐specific valvular dynamics and enable an exploration of different therapy options. The usage in a time‐constrained clinical environment requires a mitral valve model that is cost‐effective, easy to set up, parameterize and evaluate. Working towards this goal, we develop a simplified model of the mitral valve and analyse its applicability for the sketched use‐case. We propose a novel approach to simulate the mitral valve with position‐based dynamics. The resulting mitral valve model can be deformed to simulate the closing and opening, and incorporate changes caused by virtual interventions in the simulation. Ten mitral valves were reconstructed from transesophageal echocardiogram sequences of patients with normal and abnormal physiology for evaluation. Simulation results showed good agreements with expert annotations of the original image data and reproduced valve closure in all cases. In four of five pathological cases, abnormal closing behaviour was correctly reproduced. In future research, we aim to improve the parameterization of the model in terms of biomechanical correctness and perform a more extensive validation.
