Abstract
BACKGROUND Calcific mitral stenosis (calcific MS) presents a challenge for surgical treatment and is a contraindication for most contemporary transcatheter mitral valve replacement devices (TMVR), rendering patients with very limited therapeutic options. AIMS This study aims to assess the clinical and hemodynamic follow-up after mitral valve lithotripsy (MVL). METHODS All consecutive patients who underwent MVL to treat symptomatic calcific MS at St Michael's Hospital, Toronto, Canada, were included. Patients were deemed unsuitable for mitral surgery or TMVR after heart team assessment. Patients with rheumatic MS or ≥moderate mitral regurgitation (MR) were excluded. The primary endpoint was a reduction in the invasive mitral gradient by ≥50% without significant (≥moderate) MR. RESULTS Fifteen patients underwent MVL between 2021 and 2023 with a mean age of 74 ± 9 years; 53% were female, with a mean STS score of 10% ± 0.1%. Following MVL, there was a reduction in the invasively measured mean trans-mitral gradient compared to baseline (14 mmHg vs. 6 mmHg; p < 0.05). The primary endpoint was achieved in 8 patients (53%) with no major procedural complications. At follow-up (median 90 days, IQR 58-115 days), 14 (93%) patients reported improved symptoms from New York Heart Association (NYHA) Class III-IV to NYHA Class I-II (p < 0.01) with stable echo-derived mean gradient (7.7 mmHg ± 2 mmHg vs. 8.4 mmHg ± 2.9 mmHg (p = 0.7). CONCLUSIONS In selected patients with symptomatic inoperable calcific MS, MVL was safe and associated with significant short-term clinical and hemodynamic improvement. MVL may represent a new compassionate therapy for this challenging cohort. Further studies are needed to determine the long-term outcomes and help define the role of IVL technology in treating calcific valvular conditions.

Abstract
PURPOSE OF REVIEW Tricuspid transcatheter edge-to-edge repair (T-TEER) has emerged as a well tolerated and effective therapeutic option for many patients with symptomatic severe tricuspid regurgitation at prohibitive surgical risk. However, there remain several important limitations to clip-based technology in the context of other rapidly emerging percutaneous treatment options for tricuspid regurgitation. RECENT FINDINGS Tricuspid lesions pose unique challenges to treatment with the current toolbox of transcatheter clip-based technologies. This review will explore key issues related to patient factors, anatomical factors, and imaging factors that may render lesions to be unsuitable for treatment with T-TEER. SUMMARY Selection for T-TEER must include a detailed clinical evaluation in the context of a 'heart team' approach involving multiple subspecialists, with screening for patient/lesion characteristics that make T-TEER suboptimal with current clip-based technologies. Future directions for research include patient-specific 3D modeling techniques, leaflet grasping techniques, clip deployment strategies, and personalized device sizing to increase the spectrum of lesions that may be treated with T-TEER within the context of other emerging transcatheter treatment options.

Abstract
BACKGROUND Transcatheter tricuspid valve replacement (TTVR) abolishes tricuspid regurgitation (TR) and has emerged as a definitive treatment for TR. OBJECTIVES The purpose of this multicenter, observational study was to determine the clinical characteristics and short-term outcomes of patients with TR screened for TTVR. METHODS Patients underwent TTVR screening at 7 centers on a compassionate-use basis. The primary endpoints were NYHA functional class and TR grade at 30-day follow-up. Secondary endpoints included all-cause mortality, heart failure hospitalization, technical success, and reasons for TTVR screening failure. RESULTS A total of 149 patients (median age 79 years [Q1-Q3: 72-84 years], 54% women) underwent TTVR screening. The TTVR screening failure rate was 74%, mainly related to large tricuspid annular diameter. Patients undergoing TTVR (n = 38) had significant functional improvements (NYHA functional class I or II from 21% to 68%; P < 0.001), with TR ≤1+ in 97% at 30-day follow-up (P < 0.001 from baseline). Technical success was achieved in 91%, with no intraprocedural mortality or conversion to surgery. At 30-day follow-up, mortality was 8%, heart failure hospitalization 5%, major bleeding 18%, and reintervention 9%. Patients who failed screening for TTVR and subsequently underwent "bailout" transcatheter edge-to-edge repair (n = 26) had favorable outcomes (NYHA functional class I or II from 27% to 58%; P < 0.001), with TR ≤1+ in 43% at 30-day follow-up (P < 0.001 from baseline). CONCLUSIONS This first real-world report of TTVR screening demonstrated a high screening failure rate, mainly related to large tricuspid annular diameter. Patients undergoing TTVR had superior TR reduction and symptom alleviation compared with bailout tricuspid transcatheter edge-to-edge repair, at the cost of greater procedural complications.

Abstract
BACKGROUND Conduction disturbances and the need for permanent pacemaker (PPM) implantation remains a common complication for transcatheter aortic valve replacement (TAVR), particularly when self-expanding (SE) valves are used. AIMS We compared in-hospital and 30-day rates of new PPM implantation between patients undergoing TAVR with SE valves using the conventional three-cusp coplanar implantation technique and the cusp-overlap technique. METHODS We retrospectively compared patients without a pre-existing PPM who underwent a TAVR procedure with SE Evolut R or PRO valves using the cusp-overlap technique from July 2018 to September 2020 (n = 519) to patients who underwent TAVR using standard three-cusp technique from April 2016 to March 2017 (n = 128) in two high volume Canadian centers. RESULTS There was no significant difference in baseline RBBB between the groups (10.4% vs. 13.2; p = 0.35). The rate of in-hospital new complete heart block (9.4% vs. 23.4%; p ≤ 0.001) and PPM implantation (8% vs. 21%; p ≤ 0.001) were significantly reduced when using the cusp-overlap technique. The incidence of new LBBB (30.4% vs. 29%; p = 0.73) was similar. At 30 days, the rates of new complete heart block (11% vs. 23%; p ≤ 0.001) and PPM implantation (10% vs. 21%, p ≤ 0.001) remained significantly lower in the cusp-overlap group, while the rate of new LBBB (35% vs. 30%; p = 0.73) was similar. CONCLUSION Cusp-overlap approach offers several potential technical advantages compared to standard three-cusp view, and may result in lower PPM rates in TAVR with SE Evolut valve.

Abstract
BACKGROUND In the first report from the MitraBridge registry, MitraClip as a bridge to heart transplantation (HTx) proved to be at 1-year an effective treatment strategy for 119 patients with advanced heart failure (HF) who were potential candidates for HTx. We aimed to determine if benefits of MitraClip procedure as a bridge-to-transplant persist up to 2-years. METHODS By the end of the enrollment period, a total of 153 advanced HF patients (median age 59 years, left ventricular ejection fraction 26.9 ± 7.7%) with significant secondary mitral regurgitation, who were potential candidates for HTx and were treated with MitraClip as a bridge-to-transplant strategy, were included in the MitraBridge registry. The primary endpoint was the 2-year composite adverse events rate of all-cause death, first hospitalization for HF, urgent HTx or LVAD implantation. RESULTS Procedural success was achieved in 89.5% of cases. Thirty-day mortality was 0%. At 2-year, Kaplan-Meier estimates of freedom from primary endpoint was 47%. Through 24 months, the annualized rate of HF rehospitalization per patient-year was 44%. After an overall median follow-up time of 26 (9-52) months, elective HTx was successfully performed in 30 cases (21%), 19 patients (13.5%) maintained or obtained the eligibility for transplant, and 32 patients (22.5%) no longer had an indication for HTx because of significant clinical improvement. CONCLUSIONS After 2-years of follow-up, the use of MitraClip as a bridge-to-transplant was confirmed as an effective strategy, allowing elective HTx or eligibility for transplant in one third of patients, and no more need for transplantation in 22.5% of cases.

OBJECTIVES The study sought to report primary and secondary endpoints and 1-year outcomes for the full cohort of the CLASP IID trial. METHODS Prohibitive-risk patients with 3+/4+ DMR were randomized 2:1 (PASCAL:MitraClip). One-year assessments included secondary effectiveness endpoints (mitral regurgitation [MR] ≤2+ and MR ≤1+), and clinical, echocardiographic, functional, and quality-of-life outcomes. Primary safety (30-day composite major adverse events [MAE]) and effectiveness (6-month MR ≤2+) endpoints were assessed for the full cohort. RESULTS Three hundred patients were randomized (PASCAL: n = 204; MitraClip: n = 96). At 1 year, differences in survival, freedom from heart failure hospitalization, and MAE were nonsignificant (P > 0.05 for all). Noninferiority of the PASCAL system compared with the MitraClip system persisted for the primary endpoints in the full cohort (For PASCAL vs MitraClip, the 30-day MAE rates were 4.6% vs 5.4% with a rate difference of -0.8% and 95% upper confidence bound of 4.6%. The 6-month MR≤2+ rates were 97.9% vs 95.7% with a rate difference of 2.2% and 95% lower confidence bound (LCB) of -2.5%, for, respectively). Noninferiority was met for the secondary effectiveness endpoints at 1 year (MR≤2+ rates for PASCAL vs MitraClip were 95.8% vs 93.8% with a rate difference of 2.1% and 95% LCB of -4.1%. The MR≤1+ rates were 77.1% vs 71.3% with a rate difference of 5.8% and 95% LCB of -5.3%, respectively). Significant improvements in functional classification and quality of life were sustained in both groups (P <0.05 for all vs baseline). CONCLUSIONS The CLASP IID trial full cohort met primary and secondary noninferiority endpoints, and at 1 year, the PASCAL system demonstrated high survival, significant MR reduction, and sustained improvements in functional and quality-of-life outcomes. Results affirm the PASCAL system as a beneficial therapy for prohibitive-surgical-risk patients with significant symptomatic DMR.

Abstract
BACKGROUND Transcatheter mitral valve replacement (TMVR) using dedicated devices is an alternative therapy for high-risk patients with symptomatic mitral regurgitation (MR). AIMS This study aimed to assess the 2-year outcomes and predictors of mortality in patients undergoing TMVR from the multicentre CHOICE-MI Registry. METHODS The CHOICE-MI Registry included consecutive patients with symptomatic MR treated with 11 different dedicated TMVR devices at 31 international centres. The investigated endpoints included mortality and heart failure hospitalisation rates, procedural complications, residual MR, and functional status. Multivariable Cox regression analysis was applied to identify independent predictors of 2-year mortality. RESULTS A total of 400 patients, median age 76 years (interquartile range [IQR] 71, 81), 59.5% male, EuroSCORE II 6.2% (IQR 3.8, 12.0), underwent TMVR. Technical success was achieved in 95.2% of patients. MR reduction to ≤1+ was observed in 95.2% at discharge with durable results at 1 and 2 years. New York Heart Association Functional Class had improved significantly at 1 and 2 years. All-cause mortality was 9.2% at 30 days, 27.9% at 1 year and 38.1% at 2 years after TMVR. Chronic obstructive pulmonary disease, reduced glomerular filtration rate, and low serum albumin were independent predictors of 2-year mortality. Among the 30-day complications, left ventricular outflow tract obstruction, access site and bleeding complications showed the strongest impact on 2-year mortality. CONCLUSIONS In this real-world registry of patients with symptomatic MR undergoing TMVR, treatment with TMVR was associated with a durable resolution of MR and significant functional improvement at 2 years. Two-year mortality was 38.1%. Optimised patient selection and improved access site management are mandatory to improve outcomes.

Abstract
Background: Transcatheter mitral valve replacement (TMVR) is an emerging therapeutic alternative for patients with secondary mitral regurgitation (MR). Outcomes of TMVR versus guideline-directed medical therapy (GDMT) have not been investigated for this population. This study aimed to compare clinical outcomes of patients with secondary MR undergoing TMVR versus GDMT alone. Methods: The CHOICE-MI registry included patients with MR undergoing TMVR using dedicated devices. Patients with MR etiologies other than secondary MR were excluded. Patients treated with GDMT alone were derived from the control arm of the COAPT trial. We compared outcomes between the TMVR and GDMT groups, using propensity score (PS)-matching to adjust for baseline differences. Results: After PS-matching, 97 patient pairs undergoing TMVR (72.9±8.7 years, 60.8% male, transapical access 91.8%) versus GDMT (73.1±11.0 years, 59.8% male) were compared. At 1 and 2 years, residual MR was ≤1+ in all patients of the TMVR group compared to 6.9% and 7.7%, respectively, in those receiving GDMT alone (both p<0.001). The 2-year rate of HF hospitalization was significantly lower in the TMVR group (32.8% vs. 54.4%, HR 0.59, 95% CI 0.35-0.99; p=0.04). Among survivors, a higher proportion of patients were in NYHA functional class I or II in the TMVR group at 1 year (78.2% vs. 59.7%, p=0.03) and at 2 years (77.8% vs. 53.2%, p=0.09). Two-year mortality was similar in the two groups (TMVR vs. GDMT, 36.8% vs. 40.8%, HR 1.01, 95% CI 0.62-1.64; p=0.98). Conclusions: In this observational comparison, over 2-year follow-up, TMVR using mostly transapical devices in patients with secondary MR was associated with significant reduction of MR, symptomatic improvement, less frequent hospitalizations for HF and similar mortality compared with GDMT.

Abstract
BACKGROUND Mitral valve transcatheter edge-to-edge repair (M-TEER) is an effective option for treatment of mitral regurgitation (MR). We previously reported favorable 2-year outcomes for the PASCAL transcatheter valve repair system. OBJECTIVES We report 3-year outcomes from the multinational, prospective, single-arm CLASP study with analysis by functional MR (FMR) and degenerative MR (DMR). METHODS Patients with core-lab determined MR ≥ 3+ were deemed candidates for M-TEER by the local heart team. Major adverse events were assessed by an independent clinical events committee to 1 year and by sites thereafter. Echocardiographic outcomes were evaluated by the core laboratory to 3 years. RESULTS The study enrolled 124 patients, 69% FMR; 31% DMR (60% NYHA class III-IVa, 100% MR ≥ 3+). The 3-year Kaplan-Meier estimate for survival was 75% (66% FMR; 92% DMR) and freedom from heart failure hospitalization (HFH) was 73% (64% FMR; 91% DMR), with 85% reduction in annualized HFH rate (81% FMR; 96% DMR) (p < 0.001). MR ≤ 2+ was achieved and maintained in 93% of patients (93% FMR; 94% DMR) and MR ≤ 1+ in 70% of patients (71% FMR; 67% DMR) (p < 0.001). The mean left ventricular end-diastolic volume (181 mL at baseline) decreased progressively by 28 mL [p < 0.001]. NYHA class I/II was achieved in 89% of patients (p < 0.001). CONCLUSIONS The 3-year results from the CLASP study demonstrated favorable and durable outcomes with the PASCAL transcatheter valve repair system in patients with clinically significant MR. These results add to the growing body of evidence establishing the PASCAL system as a valuable therapy for patients with significant symptomatic MR.

Abstract
BACKGROUND Severe symptomatic degenerative mitral regurgitation (DMR) has a poor prognosis in the absence of treatment, and new transcatheter options are emerging. OBJECTIVES The CLASP IID (Edwards PASCAL Transcatheter Valve Repair System Pivotal Clinical Trial) randomized trial (NCT03706833) is the first to evaluate the safety and effectiveness of the PASCAL system compared with the MitraClip system in patients with significant symptomatic DMR. This report presents the primary safety and effectiveness endpoints for the trial. METHODS Patients with 3+ or 4+ DMR at prohibitive surgical risk were assessed by a central screening committee and randomized 2:1 (PASCAL:MitraClip). Study oversight also included an echocardiography core laboratory and a clinical events committee. The primary safety endpoint was the composite major adverse event rate at 30 days. The primary effectiveness endpoint was the proportion of patients with mitral regurgitation (MR) ≤2+ at 6 months. RESULTS A prespecified interim analysis in 180 patients demonstrated noninferiority of the PASCAL system vs the MitraClip system for the primary safety and effectiveness endpoints of major adverse event rate (3.4% vs 4.8%) and MR ≤2+ (96.5% vs 96.8%), respectively. Functional and quality-of-life outcomes significantly improved in both groups (P < 0.05). The proportion of patients with MR ≤1+ was durable in the PASCAL group from discharge to 6 months (PASCAL, 87.2% and 83.7% [P = 0.317 vs discharge]; MitraClip, 88.5% and 71.2% [P = 0.003 vs discharge]). CONCLUSIONS The CLASP IID trial demonstrated safety and effectiveness of the PASCAL system and met noninferiority endpoints, expanding transcatheter treatment options for prohibitive surgical risk patients with significant symptomatic DMR.

Abstract
Background Continued development of transcatheter mitral repair technologies is needed to address the large and diverse population of high-risk patients with symptomatic mitral regurgitation (MR). The new PASCAL Ace implant system, with its narrower profile, complements the original PASCAL transcatheter valve repair system. The aim of this study is to report 1-year outcomes from the early, compassionate-use observational experience with the novel PASCAL Ace implant system. Methods After heart team assessment, adults with symptomatic moderate-to-severe (3+) or severe (4+) MR despite optimal medical therapy were treated under compassionate use at 3 hospitals internationally. Data were prospectively collected, and outcomes were assessed over a 12-month follow-up period. Results Seventeen patients (mean age 76 years, 65% male, mean Society of Thoracic Surgeons Predicted Risk of Operative Mortality score 9.6) were treated. MR etiology was degenerative in 29%, functional in 65%, and mixed in 6%; 59% were in New York Heart Association (NYHA) class III-IV. Technical success was achieved in 100%, and procedural success in 94%. At 1 year, MR grade ≤2+ was achieved in 93% (p < 0.001) with 88% survival rate and 94% free from heart failure hospitalization. The composite major adverse event rate was 6% and 100% of patients had ≤NYHA class II symptoms (p < 0.001). Conclusions At 1 year, the PASCAL Ace implant system demonstrated feasibility in this early, compassionate use experience in a small group of symptomatic patients with anatomically complex MR. The unique features of the PASCAL Ace implant may expand the treatable MR population.

Abstract
Acute afterload mismatch and left ventricular dysfunction after mitral valve repair are well established. The impact of transcatheter tricuspid valve repair (TTVr) on right ventricular (RV) function is less clearly defined. To our knowledge, there are no reports of acute RV dysfunction after TTVr. Here we report a case of acute afterload mismatch after successful TTVr. (Level of Difficulty: Advanced.).

Abstract
OBJECTIVES The aim of this study was to report the midterm outcomes at 1 year in the expanded first-in-human experience with the transfemoral EVOQUE system (Edwards Lifesciences) for tricuspid regurgitation (TR). BACKGROUND Untreated TR is associated with excess mortality and morbidity. The first-in-human experience with the EVOQUE tricuspid valve replacement system reported favorable 30-day outcomes with no mortality in a compassionate use population. METHODS Twenty-seven patients with severe TR were treated with the EVOQUE system in a compassionate use experience at 7 centers between May 2019 and July 2020. All patients had clinical right-sided heart failure (HF) and were deemed inoperable and unsuitable for transcatheter edge-to-edge repair by the institutional heart teams. The clinical outcomes collected included all-cause mortality, symptom status, TR severity, HF hospitalization, and major adverse cardiovascular events. RESULTS At baseline, all patients (age: 77 ± 8 years, 89% female) were at high surgical risk (mean Society of Thoracic Surgeons score: 8.6% ± 5.5%), with 89% New York Heart Association functional class III/IV. TR was predominantly functional in etiology (19/27, 70%). At 1 year, mortality was 7% (2/27), 70% of patients were New York Heart Association functional class I/II, and 96% and 87% of patients had a TR grade ≤2+ and ≤1+, respectively. Between 30 days and 1 year, 2 patients experienced HF hospitalizations, and 1 patient required a new pacemaker implantation. CONCLUSIONS In this early, compassionate use experience, the transfemoral transcatheter EVOQUE tricuspid valve replacement system demonstrated durable efficacy, persistent improvement in symptom status, and low rates of mortality and HF hospitalizations at a 1-year follow-up. Further studies are underway to validate its efficacy.

Abstract
OBJECTIVES This study evaluated the incidence, management, and outcome of patients who experienced MitraClip (Abbott Vascular) failure secondary to loss of leaflet insertion (LLI), single leaflet detachment (SLD), or embolization. BACKGROUND Transcatheter edge-to-edge repair with MitraClip is an established therapy for the treatment of mitral regurgitation (MR), but no data exist regarding the prevalence and outcome according to the mode of clip failure. METHODS Between January 2009 and December 2020, we retrospectively screened 4,294 procedures of MitraClip performed in 19 centers. LLI was defined as damage to the leaflet where the MitraClip was attached, SLD as demonstration of complete separation between the device and a single leaflet tissue, and clip embolization as loss of contact between MitraClip and both leaflets. RESULTS A total of 147 cases of MitraClip failure were detected (overall incidence = 3.5%), and these were secondary to LLI or SLD in 47 (31.9%) and 99 (67.3%) cases, respectively, whereas in 1 (0.8%) case clip embolization was observed. MitraClip failure occurred in 67 (45.5%) patients with functional MR, in 64 (43.5%) patients with degenerative MR, and 16 (10.8%) with mixed etiology. Although the majority of MitraClip failures were detected before discharge (47 intraprocedural and 42 in the hospital), up to 39.5% of cases were diagnosed at follow-up. In total, 80 (54.4%) subjects underwent a redo procedure, either percutaneously with MitraClip (n = 51, 34.7%) or surgically (n = 36, 24.5%) including 4 cases of surgical conversion of the index procedure and 7 cases of bailout surgery after unsuccessful redo MitraClip. After a median follow-up of 163 days (IQR: 22-720 days), 50 (43.9%) subjects presented moderate to severe MR, and 43 (29.3%) patients died. An up-front redo MitraClip strategy was associated with a trend toward a reduced rate of death at follow-up vs surgical or conservative management (P = 0.067), whereas postprocedural acute kidney injury, age, and moderate to severe tricuspid regurgitation were independent predictors of death. CONCLUSIONS MitraClip failure secondary to LLI and SLD is not a rare phenomenon and may occur during and also beyond hospitalization. Redo MitraClip strategy demonstrates a trend toward a reduced risk of death compared with bailout surgery and conservative management. A third of those patients remained with more than moderate MR and had substantial mortality at the intermediate-term follow-up.

Abstract
OBJECTIVES The purpose of this study was to characterize the anatomic relationship between the inferior vena cava (IVC) and tricuspid annulus (TA) and its potential impact on the performance of transcatheter TV interventions. BACKGROUND Transcatheter tricuspid valve (TV) interventions are emerging as a therapeutic alternative for the treatment of severe, symptomatic tricuspid regurgitation (TR). Progression of TR is associated with right heart dilatation. These anatomic changes may distort the IVC-TA relationship and impact successful implantation of transcatheter devices. METHODS Fifty patients who presented with symptomatic TR for consideration of transcatheter TV therapy with an available CT were included in the study. Comprehensive transesophageal echocardiogram and CT analyses were performed to assess the right-sided cardiac chambers, TA and IVC-TA relationship. RESULTS The mean age of the study cohort was 78.4 ± 8.9 years. Torrential TR was present in 54% (n = 27). There was considerable variation in the short axis mid-IVC to mid-TA offset (SAXMID 18.2 ± 7.9 mm, range 4.7-42.1 mm). CONCLUSIONS The IVC-to-TA relationship exhibits significant variability in patients with symptomatic TR. CT analysis of the tricuspid anatomy, including the relationship to the surrounding structures and the IVC, is essential for planning transcatheter TV interventions. Further studies are needed to define whether the IVC-to-TA relationship is a predictor of technical success in the context of specific transcatheter delivery systems.

Abstract
Abstract
Aims
MitraClip treatment has been recently proposed as a ‘bridge strategy’ solution for advanced heart failure (HF) patients with significant functional mitral regurgitation (MR), who are potential candidates or are waiting for cardiac replacement therapy (LVAD or heart transplantation, HTx). In this clinical scenario, left-ventricular-related right ventricular dysfunction (RVD) represents an important prognostic factor. Our study aimed to investigate the possible prognostic implication of RVD in advanced HF patients treated with MitraClip as a bridge to HTx strategy.
Methods and results
RVD was assessed using the relationship between tricuspid annular peak systolic excursion (TAPSE) and pulmonary artery systolic pressure (PASP). All patients from the MitraBridge registry for whom these two echocardiographic parameters were available, were included in the study. A cut-off value of TAPSE/PASP ratio < 0.36 was used to defined RVD, as previously reported. The primary outcome was a composite Endpoint of all-cause death or rehospitalization for HF at 2-year. For patients who underwent LVAD implantation or HTx, follow-up data were censored at the time of those events. A total of 80 patients were included in the study. The median TAPSE/PASP ratio was 0.35 (25th–75th: 0.27–0.46), with 43 (54%) patients having a TAPSE/PASP ratio < 0.36 (RVD group). The latter had a prevalent MR ischaemic etiology (49% vs. 38%), with a more frequent history of percutaneous coronary intervention (46.5% vs. 22%, P = 0.02). Except for TAPSE (15.7 ± 3.6 mm vs. 19.2 ± 3.7 mm, P = 0.001) and PASP (61 ± 14 mmHg vs. 39.5 ± 9.5 mmHg, P < 0.001), the other echocardiographic characteristics were similar between the two study groups (overall mean left ventricular ejection fraction 26.9 ± 8%, median left ventricular end-diastolic volume index 120.7, 25th–75th: 102.2–146.5 ml/m2). After a median follow-up time of 508 (25th–75th: 160–899) days, elective HTx occurred in 12 patients (7 from the RVD group), while LVAD implantation was performed in 13 patients (7 from the RVD group). The primary outcome occurred in 30 patients (38%) with a 2-year Kaplan–Meier estimate of freedom from the composite endpoint of 41%. At univariate (HR: 1.3; 95% CI: 0.6–2.8, P = 0.451) and multivariate (HR: 1.6; CI: 0.7–3.8, P = 0.249) Cox-regression analysis, TAPSE/PASP ratio < 0.36 was not identified as an independent predictor of primary outcome. Indeed, at follow-up echocardiographic control (median time 252, 25th–75th: 122–365 days), a significant improvement in TAPSE/PASP ratio was observed in the RVD group (baseline median TAPSE/PASP ratio 0.27, 25th–75th: 0.22–0.32 vs. follow-up median TAPSE/PASP ratio 0.37, 25th–75th: 0.28–0.47, P < 0.001).
Conclusions
In advanced HF patients with functional MR, MitraClip treatment could prevent or ameliorate left-ventricular-related RVD, allowing safe access to HTx or LVAD.

Abstract
The prevalence of severe tricuspid regurgitation in older patients is high, and the clinical relevance is perceived more and more in recent years. Many of these patients are not suitable for surgery because of their age and comorbidities. Therefore, a variety of percutaneous interventions have been developed to address this unmet need. Procedural success strongly depends on adequate imaging during the intervention. Although transesophageal echocardiography is the standard of care, imaging may be limited due to anatomic factors and adverse acoustic shadowing. In this review, we discuss the current and future role of intracardiac echocardiography in tricuspid valve interventions.

Abstract
OBJECTIVES The authors report the CLASP (Edwards PASCAL Transcatheter Mitral Valve Repair System Study) expanded experience, 1-year outcomes, and analysis by functional mitral regurgitation (FMR) and degenerative mitral regurgitation (DMR). BACKGROUND The 30-day results from the CLASP study of the PASCAL transcatheter valve repair system for clinically significant mitral regurgitation (MR) have been previously reported. METHODS Eligible patients had symptomatic MR ≥3+, were receiving optimal medical therapy, and were deemed candidates for transcatheter mitral repair by the local heart team. Primary endpoints included procedural success, clinical success, and major adverse event rate at 30 days. Follow-up was continued to 1 year. RESULTS One hundred nine patients were treated (67% FMR, 33% DMR); the mean age was 75.5 years, and 57% were in New York Heart Association functional class III or IV. At 30 days, there was 1 cardiovascular death (0.9%), MR ≤1+ was achieved in 80% of patients (77% FMR, 86% DMR) and MR ≤2+ in 96% (96% FMR, 97% DMR), 88% of patients were in New York Heart Association functional class I or II, 6-min walk distance had improved by 28 m, and Kansas City Cardiomyopathy Questionnaire score had improved by 16 points (p < 0.001 for all). At 1 year, Kaplan-Meier survival was 92% (89% FMR 96% DMR) with 88% freedom from heart failure hospitalization (80% FMR, 100% DMR), MR was ≤1+ in 82% of patients (79% FMR, 86% DMR) and ≤2+ in 100% of patients, 88% of patients were in New York Heart Association functional class I or II, and Kansas City Cardiomyopathy Questionnaire score had improved by 14 points (p < 0.001 for all). CONCLUSIONS The PASCAL transcatheter valve repair system demonstrated a low complication rate and high survival, with robust sustained MR reduction accompanied by significant improvements in functional status and quality of life at 1 year.

Abstract
BACKGROUND Tricuspid regurgitation (TR) has a poor prognosis and limited treatment options and is frequently accompanied by right ventricular (RV) dysfunction. Transcatheter tricuspid valve interventions (TTVI) to reduce TR have been shown to be safe and feasible with encouraging early results. Patient selection for TTVI remains challenging, with the role of right ventricular (RV) function being unknown. AIMS The aims of this study were 1) to investigate survival in a TTVI-treated patient population and a conservatively treated TR population, and 2) to evaluate the outcome of TTVI as compared to conservative treatment stratified according to the degree of RV function. METHODS We studied 684 patients from the multicentre TriValve cohort (TTVI cohort) and compared them to 914 conservatively treated patients from two tertiary care centres. Propensity matching identified 213 pairs of patients with severe TR. As we observed a non-linear relationship of RV function and TTVI outcome, we stratified patients according to tricuspid annular plane systolic excursion (TAPSE) to preserved (TAPSE >17 mm), mid-range (TAPSE 13-17 mm) and reduced (TAPSE <13 mm) RV function. The primary outcome was one-year all-cause mortality. RESULTS TTVI was associated with a survival benefit in patients with severe TR when compared to matched controls (one-year mortality rate: 13.1% vs 25.8%; p=0.031). Of the three RV subgroups, only in patients with mid-range RV function was TTVI associated with an improved survival (p log-rank 0.004). In these patients, procedural success was associated with a reduced hazard ratio for all-cause mortality (HR 0.22; 95% CI: 0.09, 0.57). CONCLUSIONS TTVI is associated with reduced mortality compared to conservative therapy and might exert its highest treatment effect in patients with mid-range reduced RV function.

Abstract
OBJECTIVES This study reports 2-year outcomes from the multicenter, prospective, single-arm CLASP study with functional mitral regurgitation (FMR) and degenerative MR (DMR) analysis. BACKGROUND Transcatheter repair is a favorable option to treat MR. Long-term prognostic impact of the PASCAL transcatheter valve repair system in patients with clinically significant MR remains to be established. METHODS Patients had clinically significant MR ≥3+ as evaluated by the echocardiographic core laboratory and were deemed candidates for transcatheter repair by the heart team. Assessments were performed by clinical events committee to 1 year (site-reported thereafter) and core laboratory to 2 years. RESULTS A total of 124 patients (69% FMR, 31% DMR) were enrolled with a mean age of 75 years, 56% were male, 60% were New York Heart Association functional class III to IVa, and 100% had MR ≥3+. At 2 years, Kaplan-Meier estimates showed 80% survival (72% FMR, 94% DMR) and 84% freedom from heart failure (HF) hospitalization (78% FMR, 97% DMR), with 85% reduction in annualized HF hospitalization rate (81% FMR, 98% DMR). MR ≤1+ was achieved in 78% of patients (84% FMR, 71% DMR) and MR ≤2+ was achieved in 97% (95% FMR, 100% DMR) (all p < 0.001). Left ventricular end-diastolic volume decreased by 33 ml (p < 0.001); 93% of patients were in New York Heart Association functional class I to II (p < 0.001). CONCLUSIONS The PASCAL repair system demonstrated sustained favorable outcomes at 2 years in FMR and DMR patients. Results showed high survival and freedom from HF rehospitalization rates with a significantly reduced annualized HF hospitalization rate. Durable MR reduction was achieved with evidence of left ventricular reverse remodeling and significant improvement in functional status. The CLASP IID/IIF randomized pivotal trial is ongoing.

Abstract
Background As a result of the COVID-19 pandemic first wave, reductions in ST-elevation myocardial infarction (STEMI) invasive care, ranging from 23% to 76%, have been reported from various countries. Whether this change had any impact on coronary angiography (CA) volume or on mechanical support device use for STEMI and post-STEMI mechanical complications in Canada is unknown. Methods We administered a Canada-wide survey to all cardiac catheterization laboratory directors, seeking the volume of CA use for STEMI performed during the period from March 1 2020 to May 31, 2020 (pandemic period), and during 2 control periods (March 1, 2019 to May 31, 2019 and March 1, 2018 to May 31, 2018). The number of left ventricular support devices used, as well as the number of ventricular septal defects and papillary muscle rupture cases diagnosed, was also recorded. We also assessed whether the number of COVID-19 cases recorded in each province was associated with STEMI-related CA volume. Results A total of 41 of 42 Canadian catheterization laboratories (98%) provided data. There was a modest but statistically significant 16% reduction (incidence rate ratio [IRR] 0.84; 95% confidence interval 0.80-0.87) in CA for STEMI during the first wave of the pandemic, compared to control periods. IRR was not associated with provincial COVID-19 caseload. We observed a 26% reduction (IRR 0.74; 95% confidence interval 0.61-0.89) in the use of intra-aortic balloon pump use for STEMI. Use of an Impella pump and mechanical complications from STEMI were exceedingly rare. Conclusions We observed a modest 16% decrease in use of CA for STEMI during the pandemic first wave in Canada, lower than the level reported in other countries. Provincial COVID-19 caseload did not influence this reduction.

Abstract
OBJECTIVES We investigated the durability of tricuspid regurgitation (TR) reduction and the clinical outcomes through 12 months after transcatheter tricuspid valve repair (TTVr) with the PASCAL Transcatheter Valve Repair System. BACKGROUND TTVr has rapidly developed and demonstrated favorable acute outcomes, but longer follow-up data are needed. METHODS Overall, 30 patients (age 77 ± 6 years; 57% female) received PASCAL implantation from September 2017 to May 2019 and completed a clinical follow-up at 12 months. RESULTS The TR etiology was functional in 25 patients (83%), degenerative in three (10%), and mixed in two (7%). All patients had TR severe or greater (massive or torrential in 80%) and heart failure symptoms (90% in NYHA III or IV) under optimal medical treatment. Single-leaflet device attachment occurred in two patients. Moderate or less TR was achieved in 23/28 patients (82%) at 30 days, which was sustained at 12 months (86%). Two patients underwent repeat TTVr due to residual torrential TR (day 173) and recurrence of severe TR (day 280), respectively. One-year survival rate was 93%; 6 patients required rehospitalization due to acute heart failure. NYHA functional class I or II was achieved in 90% and 6-minute walk distance improved from 275 ± 122 m at baseline to 347 ± 112 m at 12-month (+72 ± 82 m, p < .01). There was no stroke, endocarditis, or device embolization during the follow-up. CONCLUSIONS Twelve-month outcomes from this multicenter compassionate use experience with the PASCAL System demonstrated high procedural success, acceptable safety, and significant clinical improvement.

Abstract
The use of exercise right heart catheterisation for the assessment of cardiovascular diseases has regained attention recently. Understanding physiologic haemodynamic exercise responses is key for the identification of abnormal haemodynamic patterns. Exercise total pulmonary resistance >3 Wood units identifies a deranged haemodynamic response and when total pulmonary resistance exceeds 3 Wood units, an exercise pulmonary artery wedge pressures/cardiac output slope >2 mmHg/l/min indicates the presence of underlying exercise-induced pulmonary hypertension related to left heart disease. In the evolving field of transcatheter interventions for valvular heart disease, exercise right heart catheterisation may objectively unmask symptoms and underlying haemodynamic abnormalities. Further studies are needed on the use of the procedure to inform the selection of patients who might receive the most benefit from transcatheter interventions for valvular heart diseases.

Abstract
BACKGROUND Transcatheter tricuspid leaflet repair (TTVr) using the MitraClip is a promising option for patients with severe tricuspid regurgitation (TR) and heart failure. However, no comparative studies of the NTR and XTR systems have been reported. OBJECTIVES The aim of this study was to assess the relative efficacy, safety, and clinical outcomes of patients with severe TR treated with the MitraClip NTR and XTR systems. METHODS Forty consecutive patients with severe TR underwent TTVr. The primary outcome was procedural success, with NYHA functional class, TR grade and major adverse cardiac and cerebrovascular events (MACCE) assessed at 30-day follow-up. RESULTS The majority of patients had functional TR and a greater proportion of XTR patients had torrential TR with larger coaptation gaps. Procedural success was achieved in 70% vs 80% in the NTR and XTR cohorts. Single leaflet device attachment was equal in both groups (5%). At 30-day follow-up, 70% vs 85% of NTR and XTR patients were in NYHA Class I/II. The mean reduction in TR grade was greater in the XTR group (1.5 ± 0.3 vs 2.3 ± 0.4, p-0.012). In patients with torrential TR at baseline, 55% in the XTR group achieved TR ≤ 2+ compared to none in the NTR group (p < 0.001). CONCLUSIONS In this first study comparing the MitraClip NTR and XTR systems for TTVr, we found both to be safe and effective, while the XTR system allowed treatment of larger coaptation gaps, greater mean reduction in TR grade, with more effective reduction of torrential TR.

Abstract
Background There has been rapid growth in the demand for transcatheter aortic valve replacement (TAVR), which has the potential to overwhelm current capacity. This imbalance between demand and capacity may lead to prolonged wait times, and subsequent adverse outcomes while patients are on the waitlist. We sought to understand the relationship between regional differences in capacity, TAVR wait times and morbidity/mortality on the waitlist. Methods and results We modelled the effect of TAVR capacity, defined as the number of TAVR procedures per million residents/region, on the hazard of having a TAVR in Ontario from April 2012 to March 2017. Our primary outcome was the time from referral to a TAVR procedure or other off-list reasons on the waitlist/end of the observation period as measured in days. Clinical outcomes of interest were all-cause mortality, all-cause hospitalisations or heart failure-related hospitalisations while on the waitlist for TAVR. There was an almost fourfold difference in TAVR capacity across the 14 regions in Ontario, ranging from 31.5 to 119.5 TAVR procedures per million residents. The relationship between TAVR capacity and wait times was complex and non-linear. In general, increased capacity was associated with shorter wait times (p<0.001), reduced mortality (HR 0.94; p=0.08) and all-cause hospitalisations (p=0.009). Conclusions The results of the present study have important policy implications, suggesting that there is a need to improve TAVR capacity, as well as develop wait-time strategies to triage patients, in order to decrease wait times and mitigate the hazard of adverse patient outcomes while on the waitlist.

Abstract
BACKGROUND The BIOFLOW-III Canada registry aimed to evaluate the safety and efficacy of Orsiro sirolimus-eluting stents (SES) with biodegradable polymer, in an all-comers patient population. METHODS We conducted a prospective, non-randomized, multi-center, observational all-comers registry of patients undergoing percutaneous coronary intervention (PCI) with Orsiro SES at two high-volume Canadian centers. The primary endpoint was one-year target lesion failure (TLF) defined as a composite of cardiac death, target-vessel myocardial infarction (MI), coronary artery bypass grafting and clinically driven target lesion revascularization. Four subgroups were pre-defined: i) diabetic patients; ii) small vessels (≤2.75 mm); iii) chronic total occlusions (CTO) and iv) acute MI. RESULTS From May 2014 to July 2016, 250 patients (mean age 66.2 ± 10.8 years, 75.6% males, 30% diabetes) underwent PCI with Orsiro SES for 385 coronary lesions. The mean stent diameter was 2.98 ± 0.50 mm and the mean stent length was 22 ± 8 mm. Clinical device and procedural success rates were with 99.5% and 97.6%, respectively. The overall one-year TLF rate was 2.8% [95% confidence interval (CI) 1.4-5.8%], whereas TLF rates were 4.1% [95%CI 1.3-12.2%], 3.2% [95%CI 1.2-8.4%], 8.3% [95%CI 2.2-29.4%], and 2.6% [95%CI 0.7-9.9%] in patients with diabetes, small vessels, CTO, and acute MI, respectively. One case of possible stent thrombosis (ST) was reported (0.4% [95%CI 0.1-2.8%]), while no cases of definite/probable ST was observed at one year. CONCLUSION Our data provide further evidence of the safety and clinical performance of Orsiro SES in an unselected, real-world, complex patient population. CONDENSED ABSTRACT The BIOFLOW-III Canada registry is a prospective, non-randomized, multi-center, observational all-comers registry designed to evaluate the safety and performance of the Orsiro SES in non-selected, real-world patients. A total of 250 patients (mean age 66.2 ± 10.8 years, 75.6% males, 30% diabetes) who underwent PCI with Orsiro SES, were enrolled at two high-volume Canadian centers. The overall rate of TLF at one year was 2.8% [95%CI 1.4-5.8%], whereas TLF rates were 4.1%, 3.2%, 8.3%, and 2.6% in patients with diabetes, small vessels ≤2.75 mm, CTO, and acute MI, respectively. No case of definite/probable ST was observed.

Abstract
Advancements in transcatheter technology has increased the number of therapeutic options for patients with tricuspid regurgitation. One category of repair devices attempts to augment leaflet coaptation by either leaflet plication or by functioning as a space occupying device. These include the MitraClip (Abbott, Santa Clara, CA, USA), PASCAL (Edwards Lifesciences, Irvine, CA, USA) and FORMA (Edwards Lifesciences, Irvine, CA, USA) devices. All three have been successfully implanted with promising short-term echocardiographic and clinical outcomes. Improvements in patient selection, device design and procedural technique will lead to more effective tricuspid regurgitation reduction. Further research to assess efficacy, safety and durability of these devices is needed, along with determination of long-term clinical outcomes.

Abstract
BACKGROUND Severe mitral regurgitation is associated with impaired prognosis if left untreated. Using the devices currently available, transcatheter mitral valve repair (TMVr) remains challenging in complex anatomical situations. We report the procedural and 30-day results of the first-in-man study of the Edwards PASCAL TMVr system. METHODS In this multicentre, prospective, observational, first-in-man study, we collected data from seven tertiary care hospitals in five countries that had a compassionate use programme in which patients underwent transcatheter mitral valve repair using the Edwards PASCAL TMVr system. Eligible patients were those with symptomatic, severe functional, degenerative, or mixed mitral regurgitation deemed at high risk or inoperable. Safety and efficacy of the procedure were prospectively assessed at device implantation, discharge, and 30 days after device implantation. The key study endpoints were technical success assessed at the end of the procedure and device success 30 days after implantation using the Mitral Valve Academic Research Consortium definitions. FINDINGS Between Sept 1, 2016, and March 31, 2017, 23 patients (median age 75 years [IQR 61-82]) had treatment for moderate-to-severe (grade 3+) or severe (grade 4+) mitral regurgitation using the Edwards PASCAL TMVr system. At baseline, the median EuroScore II score was 7·1% (IQR 3·6-12·8) and the median Society of Thoracic Surgeons predicted risk of mortality for mitral valve repair was 4·8% (2·1-9·0) and 6·8% (2·9-10·1) for mitral valve replacement. 22 (96%) of 23 patients were New York Heart Association (NYHA) class III or IV at baseline. The implantation of at least one device was successful in all patients, resulting in procedural residual mitral regurgitation of grade 2+ or less in 22 (96%) patients. Six (26%) of 23 patients had two implants. Periprocedural complications occurred in two (9%) of 23 patients (one minor bleeding event and one transient ischaemic attack). Despite the anatomical complexity of mitral regurgitation in the patients in this compassionate use cohort, technical success was achieved in 22 (96%) of 23 patients, and device success at 30 days was achieved in 18 (78%) patients. Three patients (13%) died during the 30 day follow-up. 19 (95%) of 20 patients alive 30 days after implantation were NYHA class I or II. INTERPRETATION This study establishes feasibility of the Edwards PASCAL TMVr system with a high rate of technical success and reduction of mitral regurgitation severity. Further research is needed on procedural and long-term clinical outcomes. FUNDING None.

Abstract
Severe tricuspid regurgitation is an independent predictor of adverse outcomes, yet few patients undergo surgery and treatment with medical therapy is often inadequate. Recent studies have reported the use of the MitraClip system (Abbott Vascular) to treat secondary tricuspid regurgitation. We describe the first use of MitraClip to treat severe primary tricuspid regurgitation and right heart failure in a patient with previous cardiac transplantation and high surgical risk.
