RESUMO

Aortic regurgitation (AR) is associated with left ventricular volume and pressure overload, resulting in eccentric left ventricular (LV) remodeling and enlargement. This condition may be well tolerated for years before the onset of myocardial dysfunction and symptoms. Echocardiography plays a crucial role in the diagnosis of AR, assessing its mechanism and severity, and detecting LV remodeling. The assessment of AR severity is challenging and frequently requires the integration of information from multiple different measurements to assess the severity. Recent data suggests that echocardiographically derived LV volumes (end-systolic volume index > 45 ml/m2), an ejection fraction threshold of <60%, and abnormal global longitudinal strain may help identify early dysfunction and may be used to improve clinical outcomes. Consequently, these parameters can identify candidates for surgery. Cardiac magnetic resonance imaging is emerging as a valuable tool for assessing severity when it remains unclear after an echocardiographic evaluation. This review emphasizes the importance of imaging, particularly echocardiography, in the evaluation of AR. It focuses on various echocardiographic parameters, including technical details, and how to integrate them for assessing the mechanism and severity of AR, as well as LV remodeling.

RESUMO

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is a well-established intervention for severe aortic valve stenosis. However, its application for severe aortic regurgitation (AR) is still under evaluation. This study aims to present the 3-year follow-up outcomes of the J-Valve system in managing severe AR. AIMS: The aim of this study was to evaluate the mid-term efficacy and durability of the J-Valve system in the treatment of severe AR and to provide new information on this intervention. METHODS: In this retrospective, single-center study, we evaluated the prognostic outcomes of patients with AR, who underwent treatment with the J-Valve system at Nanjing Drum Tower Hospital. Consecutive patients who were treated with the J-Valve were included in the analysis. The study focused on the echocardiographic follow-up to assess the effectiveness and durability of the J-Valve system in managing AR. RESULTS: From January 2018 to December 2022, 36 high-risk AR patients treated with the J-Valve system had a procedural success rate of 97.2%, with one case requiring open-heart surgery due to valve displacement. Significant improvements were observed in left ventricular diameter (from 63.50 [58.75-69.50] mm to 56.50 [53.00-60.50] mm, p < 0.001) and left atrial diameter (from 44.00 [40.00-45.25] mm to 39.00 [36.75-41.00] mm, p = 0.003) postsurgery. All patients completed the 1-year follow-up, with an overall mortality rate of 2 out of 36 (5.6%). Among the surviving patients, there was one case of III° atrioventricular block and one case of stroke, both occurring within 90 days postsurgery. After a 3-year follow-up, 15.0% of patients had mild or moderate valvular regurgitation, with no cases of moderate or severe paravalvular leak. Additionally, 89.5% of patients were classified as New York Heart Association class I or II, showing significantly enhanced cardiac function. CONCLUSION: The J-Valve system has shown positive therapeutic outcomes in treating AR, with notable effectiveness in managing the condition and significant improvements in heart failure symptoms and cardiac remodeling. However, due to the limited sample size and partial follow-up data, it is important to emphasize the need for further research with comprehensive long-term follow-up, to fully validate these results.

RESUMO

Background: In recent years, transcatheter aortic valve replacement (TAVR) has emerged as a pivotal treatment for pure native aortic regurgitation (PNAR). Given patients with severe aortic regurgitation (AR) are prone to suffer from pulmonary hypertension (PH), understanding TAVR's efficacy in this context is crucial. This study aims to explore the short-term prognosis of TAVR in PNAR patients with concurrent PH. Methods: Patients with PNAR undergoing TAVR at Zhongshan Hospital, Affiliated with Fudan University, were enrolled between June 2018 to June 2023. They were categorized based on pulmonary artery systolic pressure (PASP) into groups with or without PH. The baseline characteristics, imaging records, and follow-up data were collected. Results: Among the 103 patients recruited, 48 were afflicted with PH. In comparison to PNAR patients without PH, the PH group exhibited higher rates of renal dysfunction (10.4% vs. 0.0%, p = 0.014), increased Society of Thoracic Surgeons scores (6.4 ± 1.9 vs. 4.7 ± 1.6, p < 0.001), and elevated Nterminal fragment of pro-brain natriuretic peptide (NT-proBNP). Transthoracic ultrasound examination revealed that patients with PH displayed lower left ventricular ejection fraction, larger left ventricle dimension, and more frequent moderate to severe tcuspid regurgitation (TR). Following TAVR, both groups experienced significant reductions in PASP, mitral regurgitation (MR) and TR. There were no significant differences in the incidence of postoperative adverse events in patients with or without PH. Conclusions: We found TAVR to be a safe and effective treatment for patients with PNAR and PH, reducing the degree of aortic regurgitation and PH without increasing the risk of postoperative adverse events.

RESUMO

Multivalvular heart disease (MVHD) is present in one-third of patients with valvular heart disease (VHD). Compared to single VHD patients, these patients have a more significant hemodynamic impact and are often left under medical treatment. Most importantly, when undergoing multiple valve interventions, they show worse rates of heart failure and mortality. The guidelines-supported interventions in patients with MVHD in combined aortic regurgitation and mitral stenosis include percutaneous mitral balloon commissurotomy, open mitral commissurotomy, or surgical mitral valve replacement followed by transcatheter or surgical aortic valve replacement, trying to minimize the increased mortality risk of double-valve replacement. Simultaneous transcatheter valve replacement (STVR) for native MVHD is still off-label and not yet considered in clinical guidelines since the evidence of its results is limited to a few cases reported worldwide. However, fully percutaneous transfemoral STVR seems promising for MVHD patients thanks to its minimal invasiveness, the continuous improvement of the transcatheter heart valve devices, the likely shorter length of stay and the fastest recovery. To our knowledge, this is the first case ever reported of fully percutaneous STVR for native MVHD in aortic regurgitation and mitral stenosis. Deep understanding of both pathologies and their interactions, not only from a pathological point of view but from the procedural planning and procedural steps point of view is mandatory. Hereby we present the specific STVR procedural planning considerations, a step-by-step guide on how to perform an aortic and mitral STVR and its critical considerations, as well as the procedural and follow-up results.

RESUMO

OBJECTIVES: Both aortic root remodelling and aortic valve (AV) reimplantation have been used for valve-sparing root replacement in patients with aortic root aneurysm with or without aortic regurgitation. There is no clear evidence to support one technique over the another. This study aimed to compare remodelling with basal ring annuloplasty versus reimplantation on a multicentre level with the use of propensity-score matching. METHODS: This was a retrospective international multicentre study of patients undergoing remodelling or reimplantation between 2010 and 2021. Twenty-three preoperative covariates (including root dimensions and valve characteristics) were used for propensity-score matching. Perioperative outcomes were analysed along with longer-term freedom from AV reoperation/reintervention and other major valve-related events. RESULTS: Throughout the study period, 297 patients underwent remodelling and 281 had reimplantation. Using propensity-score matching, 112 pairs were selected and further compared. We did not find a statistically significant difference in perioperative outcomes between the matched groups. Patients after remodelling had significantly higher reintervention risk than after reimplantation over the median follow-up of 6 years (P = 0.016). The remodelling technique (P = 0.02), need for decalcification (P = 0.03) and degree of immediate postoperative AV regurgitation (P < 0.001) were defined as independent risk factors for later AV reintervention. After exclusion of patients with worse than mild AV regurgitation immediately after repair, both techniques functioned comparably (P = 0.089). CONCLUSIONS: AV reimplantation was associated with better valve function in longer-term postoperatively than remodelling. If optimal immediate repair outcome was achieved, both techniques provided comparable AV function.

RESUMO

AIMS: To evaluate the safety and efficacy of transcatheter aortic valve implantation (TAVI) for the treatment of aortic regurgitation (AR). METHODS: From September 2019 to February 2022, 62 patients who underwent transfemoral TAVI procedure for pure, symptomatic severe AR with the VitaFlow system were enrolled in the current study. The outcomes were assessed according to the Valve Academic Research Consortium 3 criteria. Procedural results and clinical outcomes for 1 year were analyzed. RESULTS: The mean age was 71.56 ± 7.34 years and 58.1% were male. The mean Society of Thoracic Surgeons score was 5.44 ± 3.22%. The device success rate was 79.0%. Only one patient was converted to open surgery. The in-hospital mortality rate was 1.6%. The 1-year all-cause mortality rate was 6.5%. The new permanent pacemaker implantation rate was 29.0% in-hospital and 30.7% at 1-year follow-up. The second valve implantation rate was 14.5%. No patient developed more than moderate paravalvular leakage during follow-up. The mean ejection fraction improved from 54.05 ± 10.83% at baseline to 59.32 ± 8.70% (p < 0.001 compared with baseline) at 12 months. Left ventricular end-diastolic diameter decreased from 61.62 ± 5.58 mm at baseline to 55.20 ± 4.51 mm (p < 0.001 compared with the baseline) at 12 months. CONCLUSIONS: Transfemoral TAVI procedure shows efficacy in treating patients with severe pure native AR. The safety is improved with the development of the VitaFlow system.

RESUMO

Background: Limited data exist on strain changes after transcatheter aortic valve implantation (TAVI) in patients with aortic regurgitation (AR). Case summary: Three patients with AR undergoing TAVI showed an initial reduction in global longitudinal strain (GLS), followed by sustained GLS improvement within the first year. Discussion: Findings align with those of surgically treated patients with AR. There is a possible superiority of GLS to left ventricular end-diastolic diameter ratio in assessing patients with severe volume overload.

RESUMO

BACKGROUND: Patients with concomitant type 2 diabetes mellitus (T2DM) and aortic regurgitation (AR) can present with right ventricular (RV) dysfunction. The current study aimed to evaluate the impact of AR on RV impairment and the importance of ventricular interdependence using cardiac magnetic resonance feature tracking (CMR­FT) in patients with T2DM. METHODS: This study included 229 patients with T2DM (AR-), 88 patients with T2DM (AR+), and 122 healthy controls. The biventricular global radial strain (GRS), global circumferential strain (GCS), and global longitudinal peak strain (GLS) were calculated with CMR­FT and compared among the healthy control, T2DM (AR-), and T2DM (AR+) groups. The RV regional strains at the basal, mid, and apical cavities between the T2DM (AR+) group and subgroups with different AR degrees were compared. Backward stepwise multivariate linear regression analyses were performed to determine the effects of AR and left ventricular (LV) strains on RV strains. RESULTS: The RV GLS, LV GRS, LV GCS, LV GLS, interventricular septal (IVS) GRS and IVS GCS were decreased gradually from the controls through the T2DM (AR-) group to the T2DM (AR+) group. The IVS GLS of the T2DM (AR-) and T2DM (AR+) groups was lower than that of the control group. AR was independently associated with LV GRS, LV GCS, LV GLS, RV GCS, and RV GLS. If AR and LV GLSs were included in the regression analyses, AR and LV GLS were independently associated with RV GLS. CONCLUSION: AR can exacerbate RV dysfunction in patients with T2DM, which may be associated with the superimposed strain injury of the left ventricle and interventricular septum. The RV longitudinal and circumferential strains are important indicators of cardiac injury in T2DM and AR. The unfavorable LV-RV interdependence supports that while focusing on improving LV function, RV dysfunction should be monitored and treated in order to slow the progression of the disease and the onset of adverse outcomes.

RESUMO

AIMS: To characterize left atrial (LA) and left ventricular (LV) function and atrioventricular (AV) coupling in patients with moderate mixed aortic valve disease (MMAVD) against those with isolated moderate or severe aortic valve disease and controls. METHODS & RESULTS: Retrospective LA and LV peak longitudinal strain (LS) analysis were performed on 260 patients (46 MMAVD, 81 moderate aortic stenosis (AS), 50 severe AS, 48 moderate aortic regurgitation (AR), and 35 severe AR) and 66 controls. Peak LV and LA LS and AV coupling, assessed by combined peak LA and LV strain, was compared between the groups. ANOVA and 2-sided t-tests were used and a p-value of <0.01 was considered significant.LV strain was significantly lower in those with MMAVD compared to controls and those with moderate or severe isolated AR but comparable to those with moderate or severe AS (-17.1±1.1% MMAVD vs. -17.7±1.5% moderate AS p=0.02; vs. -17.0%±1.5% severe AS, p=0.74). AV coupling was significantly lower in those with MMAVD compared to controls and those with moderate AS or AR but comparable to those with severe AS or AR (47.1±6.8% MMAVD vs. 45.1±5.6% severe AS, p=0.13; vs. 50.4±9% severe AR, p=0.07). CONCLUSIONS: Impairments in AV coupling are comparable for patients with MMAVD and those with severe isolated AS or AR. Impairments in LV GLS in MMAVD mirror those found in severe AS. These findings suggest that haemodynamic consequences and adverse remodelling are similar for patients with MMAVD and isolated severe disease.

RESUMO

BACKGROUND: The timing of treatment for chronic aortic valve regurgitation (AR), especially in asymptomatic patients, is gaining attention since less invasive strategies have become available. The aim of the present study was to evaluate left ventricular reverse remodeling after aortic valve replacement (AVR) for severe AR. METHODS: Patients (n = 25) who underwent surgical AVR for severe AR with left ventricular ejection fraction (LVEF) less than 55% were included in this study. Preprocedural and follow-up clinical and echocardiographic measurements of LVEF and left ventricular (LV) diameters were retrospectively analyzed. RESULTS: Mean LVEF increased significantly following surgical AVR (p < 0.0001). LV diameters showed a clear regression (p = 0.0088). Younger patients and those receiving a mechanical valve tended to have less improved LVEF on follow-up than patients over 60 years or the ones who were implanted with a biological prosthesis (p = 0.0239 and p = 0.069, respectively). Gender had no effect on the degree of LVEF improvement (p = 0.4908). CONCLUSIONS: We demonstrated significant LV reverse remodeling following AVR for AR. However, more data are needed on LV functional and geometrical improvement comparing the different types of valve prostheses to provide an optimal treatment strategy.

RESUMO

BACKGROUND: The off-label utilization of transcatheter heart valve (THV) devices for the treatment of inoperable or high-surgical risk patients with pure native aortic valve regurgitation (NAVR) has demonstrated suboptimal outcomes, both with self- and balloon-expandable (BE) devices. The aim of this study is to compare the use of different BE scaffolds in treating pure NAVR. METHODS: Consecutive patients with pure severe NAVR who were deemed to be at high-risk and were treated with last-generation BE-THVs among seventeen Centers in Europe and US. Technical and device success rates were the primary objectives. RESULTS: Between February 2018 and July 2023, among 144 patients, 41 (28 %) received a MyVal device and 103 (72 %) were treated with a Sapien THV. Patients treated with a MyVal THV had an extra-large annulus more frequently compared to the Sapien group (49%vs.20 %, p < 0.001). Technical and device success rates were 90 % and 81 %, respectively, p > 0.1. The rate of THV migration/embolization (MyVal 4.9%vs. Sapien 11 %, p = 0.4) and second valve needed (4.9%vs.7.8 %, p = 0.7) were numerically lower in the MyVal group, whereas the rate of at least moderate paravalvular leak (15%vs.7.8 %, p = 0.2) and permanent pacemaker implantation (25%vs.18 %, p = 0.16) were numerically higher in the Myval group. CONCLUSIONS: Off-label use of BE devices for pure NAVR represents a potential alternative in high-risk patients in the absence of dedicated devices. However, BE in NAVR is associated with suboptimal outcomes. The availability of larger THV sizes may introduce transcatheter aortic valve replacement as an effective treatment for patients traditionally deemed unsuitable. NON-STANDARD ABBREVIATIONS AND ACRONYMS: AR = aortic regurgitation, BE = balloon-expandable, NAVR = native aortic valve regurgitation, PM = pacemaker, TAVR = transcatheter aortic valve replacement, THV = transcatheter heart valve, TVEM = transcatheter valve embolization and migration, VARC-3 = Valve Academic Research Consortium 3.

RESUMO

BACKGROUND: To examine whether left atrial (LA) strain was associated with adverse outcomes in asymptomatic chronic aortic regurgitation (AR). METHODS: Asymptomatic patients with ≥moderate-severe AR were retrospectively identified from 2008 through 2022 from a university hospital. Apical 4-chamber left ventricular longitudinal strain (A4C-LVLS), LA reservoir (LASr), conduit (LAScd), and contractile strain (LASct) were measured using fully-automated software. Primary endpoint was all-cause death (ACD); secondary endpoints were heart failure (HF) development or aortic valve surgery (AVS). RESULTS: Of 352 patients (59 ± 17 years; 19 % female), the mean LV ejection fraction (LVEF) was 60 ± 8 %. The median follow-up during medical surveillance was 4.7 (interquartile range: 1.8-9.0) years; during which 68 patients died. Multivariable analysis adjusted for covariates showed that larger maximal LA volume index (iLAVmax), lower LASr and LASct were independently associated with ACD (all P ≤ 0.047); A4C-LVLS and LAScd were not (P ≥ 0.15). Besides, iLAVmax, LASr, and LASct provided incremental prognostic value over A4C-LVLS in terms of ACD (all P ≤ 0.048). HF symptoms occurred in 126 patients at a median of 2 years. Multivariable determinants for HF development included larger minimal LAV index, lower LASr and LASct (all P ≤ 0.03). Adjusted spline curves showed LASr <38-40 % and LASct <20-24 % were associated with increased risks of ACD and HF development, respectively. Using abovementioned LASr and LASct cutoffs, adjusted Kaplan-Meier curves risk-stratified patients for ACD successfully (P ≤ 0.02). Lower LASr was also independently associated with AVS (Hazard ratio per 1 % increase: 0.98)(P = 0.02). CONCLUSIONS: In patients with asymptomatic AR, fully-automated LASr and LASct were robust markers for outcome determination; these markers may identify those who need timely surgical referral.

RESUMO

Background: The improvement rate and predictors of secondary mitral regurgitation in patients with aortic regurgitation undergoing transcatheter aortic valve replacement (TAVR) remain unclear. This study aimed to identify predictors of persistent moderate to severe secondary mitral regurgitation after TAVR in patients with aortic regurgitation by assessing mitral valve geometry with computed tomography (CT). Methods: This retrospective cohort study reviewed 242 consecutive patients with aortic regurgitation who underwent TAVR between May 2014 and December 2022. Patients with primary or less than moderate mitral regurgitation were excluded. Mitral annular dimensions (area, perimeter, anteroposterior, intercommissural, and trigone-to-trigone diameter), mitral valve tenting geometry (mitral valve tenting area [MVTA] and mitral valve tenting height [MVTH]), and papillary muscle displacement were systematically measured at CT. Mitral regurgitation improvement was assessed at 3 months after TAVR by echocardiography. Logistic regression was performed to explore the association of mitral valve geometry with mitral regurgitation improvement after TAVR. Results: A total of 75 patients (mean age, 74 ± 7 years; 32.0% female) with moderate to severe secondary mitral regurgitation were included in the final analysis. Mitral regurgitation improved in 49 patients and remained unchanged in 26 patients. Mitral annular dimensions, including area, perimeter, anteroposterior, and intercommissural diameter, were associated with mitral regurgitation improvement. MVTA and MVTH were risk factors for sustained mitral regurgitation. In addition, QRS duration > 120 ms and atrial fibrillation had an impact on the mitral regurgitation improvement. Mitral annular area (odds ratio [OR], 1.41; 95% confidence interval [CI]: 1.05, 1.90; p = 0.02) and MVTA (OR, 7.24; 95% CI: 1.72, 30.44; p = 0.007) were independent predictors of persistent secondary mitral regurgitation after TAVR. Conclusions: Mitral annular area and MVTA were independent predictors of persistent secondary mitral regurgitation after TAVR.

RESUMO

BACKGROUND: Aortic regurgitation with dilated annulus presents a technical challenge for conventional transcatheter aortic valve implantation (TAVI) procedures. CASE PRESENTATION: We report a case of an 84-year-old frail patient with a history of breathlessness found to have severe aortic regurgitation and moderately impaired left ventricular systolic function. The patient underwent a successful TAVI procedure using the XL-Myval 32 mm transcatheter heart valve (THV) via an anterior right mini-thoracotomy with a direct aortic approach. The patient recovered well post-operatively with good hemodynamic resolution. CONCLUSIONS: This first in human case highlights the efficacy and potential of applying innovative approaches, such as the new sizes of Myval THV and direct aortic access via anterior right mini thoracotomy, in addressing challenging anatomical variations in TAVI procedures with good outcome.

RESUMO

Quadricuspid aortic valve (QAV), a rare congenital cardiac anomaly, often presents with aortic regurgitation and can lead to significant cardiovascular complications. This case report describes a 55-year-old male with a history of subarachnoid hemorrhage who was incidentally found to have QAV with possible endocarditis. Transesophageal echocardiography revealed thickened leaflet tips on all four cusps and a mass on one leaflet, raising suspicion of endocarditis despite the absence of vegetation. The patient was treated with intravenous antibiotics for Gram-positive bacteremia, and follow-up imaging confirmed the QAV anomaly with moderate aortic regurgitation. This case highlights the challenges in diagnosing QAV, particularly in asymptomatic individuals, and underscores the need for comprehensive investigation, especially in those with a history of vascular events. It also emphasizes the importance of further research to clarify the long-term risks and optimal management strategies for individuals with QAV, including the potential for infective endocarditis.

RESUMO

BACKGROUND: Aortic regurgitation is distinguished by the backflow of blood from the aorta into the left ventricle. American College of Cardiology/American Heart Association guidelines recommend surgical aortic valve replacement (SAVR) for patients with symptomatic aortic regurgitation (sAR). This study estimates the difference in mortality, health care use, and costs between patients with sAR who receive SAVR within 12 months of diagnosis versus those who do not. METHODS AND RESULTS: We used the Optum United Healthcare database to identify 132 317 patients diagnosed with sAR from 2016 to 2021 who had at least 6 months of enrollment before sAR and 12 months of enrollment after. Criteria were no history of aortic stenosis or transcatheter aortic valve replacement and ≥2 visits for heart failure, angina, dyspnea, or syncope. Outcomes were all-cause mortality, health care use, and annualized cost. Baseline differences in demographics and comorbidities were adjusted with inverse propensity score weighting. We modeled survival and estimated health care use and costs using Cox proportional hazards and general linear models, respectively. Of the 132 317 patients, 400 underwent SAVR within 12 months of diagnosis. They were on average younger, more often men, and with a slightly higher Elixhauser Comorbidity Index score. After inverse propensity score weighting, patients with sAR who had SAVR had lower mortality, fewer inpatient and emergency department visits, fewer hospital days, and lower annualized cost. CONCLUSIONS: SAVR performed within 12 months of an sAR diagnosis is associated with improved mortality and lower annualized health care use and costs. These clinical and economic benefits should be considered when managing patients with sAR.

RESUMO

Surgical aortic valve replacement (SAVR) is the recommended curative treatment for pure native aortic regurgitation (AR). However, some patients are not suitable for SAVR due to comorbidities or frailty. Transcatheter aortic valve replacement (TAVR) has been reported to offer a better prognosis than medical therapy in AR patients; thus, the use of TAVR for AR may increase in the future. However, the reduced calcification and annulus ring stiffness associated with TAVR may increase the risk of valve migration. Accumulating data on rescue measures in the event of valve migration is necessary. An 87-year-old female with a history of hypertension and persistent atrial fibrillation presented to our emergency department with dyspnea. The patient was diagnosed with congestive heart failure class IV, according to the New York Heart Association classification, necessitating urgent admission to our cardiac department. Due to the patient's high surgical risk (Society of Thoracic Surgeons (STS) score 9.17%, Euro2 score 9.55%, frailty 6), the heart team performed TAVR with a right femoral arterial approach. The patient was sedated, and pacing was initiated at 180 bpm. We placed an Edwards SAPIEN 3 valve (Edwards Lifesciences, Irvine, CA, USA) #23 (-1 mL volume, with attached balloon). During the post-deployment procedure, the aortic valve migrated retrogradely into the left ventricle (LV). Despite the occurrence of severe aortic valve regurgitation, the patient's vital signs remained stable. Five minutes after the migration of the aortic valve, venoarterial extracorporeal membrane oxygenation (VA-ECMO) was initiated. A second TAVR valve implantation was then performed. However, after the second valve implantation and the removal of the pre-shaped guidewire (Safari2 pre-shaped guidewire extra small, Boston Scientific, Marlborough, MA, USA), the migrated valve became stuck in the left ventricular outflow tract (LVOT) in a reverse position, resulting in severely limited left ventricular ejection. We increased the support provided by VA-ECMO, and surgical conversion to SAVR was performed without experiencing circulatory collapse. Surgical aortic valve replacement was initiated successfully, and withdrawal of the cardiopulmonary bypass (CPB) was performed without complications. The patient was extubated on the first postoperative day (POD), discharged from the ICU on POD 3, and transferred for rehabilitation on POD 27. In summary, the prompt introduction of VA-ECMO was important for avoiding complications and saving the patient's life following the retrograde migration of the TAVR valve.
