BackgroundAortic stenosis (AS) and coronary artery disease (CAD) frequently coexist, requiring careful revascularisation strategy consideration. While surgical aortic valve replacement (SAVR) plus coronary artery bypass grafting (CABG) is traditional, transcatheter aortic valve replacement (TAVR) plus percutaneous coronary intervention (PCI) is increasingly used. The optimal strategy, particularly regarding residual CAD burden, remains unclear.ObjectivesThis study investigated the impact of residual SYNTAX (Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery) score (rSS) on outcomes in men and women with AS and CAD undergoing TAVR+PCI versus SAVR+CABG.MethodsIn this retrospective study, propensity score-matched cohorts of men and women undergoing either procedure were analysed. Matching variables included age, left ventricular ejection fraction, EuroSCORE II (European System for Cardiac Operative Risk Evaluation II) and CAD severity.Results398 patients (114 women and 284 men) were included. The rSS was predictive of the primary composite endpoint in the TAVR+PCI group (p=0.006 women and p<0.001 men) but not in the SAVR+CABG group. In patients achieving an rSS<8, TAVR+PCI was associated with a lower combined endpoint rate compared with SAVR+CABG, consistent across genders (p=0.02). Furthermore, TAVR+PCI demonstrated significant safety benefits, including lower rates of major bleeding in men (2.1% vs 10.6%) and stroke in women (1.8% vs 12.3%).ConclusionsThe prognostic importance of the rSS is strategy-dependent. For patients undergoing TAVR+PCI, achieving extensive revascularisation (rSS <8) is a critical procedural goal associated with improved outcomes. For patients undergoing SAVR+CABG, prognosis appears driven more by baseline clinical risk.

ObjectivesThis study aimed to compare hemodynamic characteristics of different self-expanding (SE) and balloon-expandable (BE) transcatheter heart valves (THV) in relation to native aortic annulus anatomy.BackgroundA patient centered THV selection becomes increasingly important as indications for transcatheter aortic valve replacement (TAVR) are extended towards lower risk populations.MethodsHemodynamic parameters including mean gradient (MG), effective orifice area (EOA), Doppler velocity index (DVI), degree of paravalvular regurgitation (PVR) and patient-prosthesis mismatch (PPM) were compared by valve type, label size and in relation to quintiles of native aortic annulus area.Results2609 patients were treated at 3 centers in Germany with SAPIEN 3 (n = 1146), ACURATE Neo (n = 649), Evolut R (n = 546) or Evolut Pro (n = 268) THV. SE THVs provided superior hemodynamics in terms of larger EOA, higher DVI and lower MG compared to BE THV, especially in patients with small aortic annuli. Severe PPM was less frequent in SE treated patients. The rate of PVR ≥ moderate was comparable for SE and BE devices in smaller annular dimensions, but remarkably lower for BE TAVR in large aortic annular dimensions (> 547.64 mm2) (2% BE THV vs. > 10% for SE THV; p < 0.001).ConclusionsPatients with small aortic annular dimensions may benefit hemodynamically from SE THV. With increasing annulus size, BE THV may have advantages since PVR ≥ moderate occurs less frequently.

BackgroundTranscatheter repair emerges as a treatment option in patients with tricuspid regurgitation (TR) and high surgical risk.AimsThis study aimed to compare leaflet-based and annuloplasty-based transcatheter repair in patients with TR.MethodsIn a retrospective analysis consecutive patients undergoing either transcatheter edge-to-edge repair (TEER) or direct annuloplasty (AP) for relevant TR at 2 centers were compared with respect to baseline characteristics, procedural efficacy and safety (death, myocardial infarction, procedure or device-related cardiothoracic surgery, or stroke at 30 days).Results161 patients (57% female, median age 79 [75–82] years) with comparable clinical baseline characteristics in the TEER (n = 87) and AP (n = 74) group were examined. Baseline TR grade was significantly less severe in the TEER compared to the AP group (torrential 9.2 vs. 31.1%, p = 0.001). Technical success and improvement of TR grades were not significantly different across groups. In analysis matched for baseline TR severity, reduction of TR grade to less than moderate was significantly more common in the AP group (47.8 vs. 26.1%, p = 0.031). Major or more severe bleeding occurred in 9.2% of TEER and 20.3% of AP patients (p = 0.049) without any fatal bleedings. Major adverse events (MAE) were similar across groups with four patients (4.7%) in the TEER group and five patients (6.9%) in the AP group (p = 0.733) and 6-month survival did not differ significantly.ConclusionsDifferences observed between patients treated with TEER and AP provide first evidence for tailoring distinct transcatheter treatment techniques to individual patient characteristics.Graphic abstract

BackgroundThe PASCAL system is a novel device for edge-to-edge treatment of mitral regurgitation (MR). The aim of this study was to compare the safety and efficacy of the PASCAL to the MitraClip system in a highly selected group of patients with complex primary mitral regurgitation (PMR) defined as effective regurgitant orifice area (MR-EROA) ≥ 0.40 cm2, large flail gap (≥ 5 mm) or width (≥ 7 mm) or Barlow’s disease.Methods38 patients with complex PMR undergoing mitral intervention using PASCAL (n = 22) or MitraClip (n = 16) were enrolled. Primary efficacy endpoints were procedural success and degree of residual MR at discharge. The rate of major adverse events (MAE) according to the Mitral Valve Academic Consortium (MVARC) criteria was chosen as the primary safety endpoint.ResultsPatient collectives did not differ relevantly regarding pertinent baseline parameters. Patients` median age was 83.0 [77.5–85.3] years (PASCAL) and 82.5 [76.5–86.5] years (MitraClip). MR-EROA at baseline was 0.70 [0.68–0.83] cm2 (PASCAL) and 0.70 [0.50–0.90] cm2 (MitraClip), respectively. 3D-echocardiographic morphometry of the mitral valve apparatus revealed no relevant differences between groups. Procedural success was achieved in 95.5% (PASCAL) and 87.5% (MitraClip), respectively. In 86.4% of the patients a residual MR grade ≤ 1 + was achieved with PASCAL whereas reduction to MR grade ≤ 1 + with MitraClip was achieved in 62.5%. Neither procedure time number of implanted devices, nor transmitral gradient differed significantly. No periprocedural MAE according to MVARC occured.ConclusionIn this highly selected patient group with complex PMR both systems exhibited equal procedural safety. MitraClip and PASCAL reduced qualitative and semi-quantitative parameters of MR to an at least comparable extent.Graphic abstract

Both the MitraClip and PASCAL systems offer transcatheter edge-to-edge repair (TEER) solutions for mitral regurgitation. Evidence indicates a lower technical success rate for TEER in complex degenerative mitral regurgitation (DMR) cases. We conducted a retrospective analysis of patients who underwent transcatheter edge-to-edge therapy for primary mitral regurgitation with advanced anatomy, defined as mitral regurgitation effective regurgitant orifice area (MR-EROA) ≥0.40 cm2 or large flail gap (≥5 mm) or width (≥7 mm) or Barlow’s disease, that completed follow-up after 1 year. Our criteria were met by 27 patients treated with PASCAL and 18 with MitraClip. All patients exhibited a significant, equivalent short-term reduction in MR-EROA, mitral regurgitation vena contracta diameter (MR-VCD), regurgitant volume, and clinical status. At 1 year follow-up, reductions in MR-VCD, regurgitant volume, and MR-EROA remained significant for both groups without significant differences between groups. MR-Grade ≤ 1+ was achieved in 18 (66.7%) and 10 (55.6%) patients, respectively. At follow-up, no difference in hospitalization for cardiac decompensation was observed. Overall death was similar in both groups. Our study suggests that both the PASCAL and MitraClip systems significantly reduce mitral regurgitation even in advanced degenerative diseases. Within our limited data, we found no evidence of inferior performance of the PASCAL system.

Aims: Interventional transcatheter edge-to-edge mitral valve repair (TMVR) is an established treatment option for patients with severe mitral regurgitation (MR) and high operative risk. Cognitive impairment is one of the most common conditions among often extensive comorbidities in these patients. The specific patterns of cognitive decline and particularly the effect of TMVR are not well described. Thus, this study aimed to investigate into the impact of TMVR on cognitive impairment, exercise capacity, and quality of life. Methods: Cognitive function (executive, naming, memory, attention, language, abstraction, and orientation) was assessed with the standardized Montreal Cognitive Assessment test (MoCA; range between 0 and 30 points) before and 3 months after TMVR in 72 consecutive patients alongside echocardiographic examination and assessment of exercise capacity (six-minute walk test) as well as quality-of-life questionnaires (Minnesota living with heart failure questionnaire, MLHF-Q). Results: Patients’ median age was 81 [76.0; 84.5] years, 39.7% were female with a median EuroScore II of 4.4% [2.9; 7.7]. The assessment of cognitive function showed a significant improvement of the cumulative MoCA-Test result (from 22.0 [19.0; 24.5] to 24 [22.0; 26.0]; p < 0.001) with significant changes in the subcategories executive (p < 0.001), attention (p < 0.001), abstraction (p < 0.001), and memory (p < 0.001). In addition, quality of life (from 47.5 [25.0; 69.3] to 24.0 [12.0; 40.0]; p < 0.001) and exercise capacity (from 220.0 m [160.0; 320.0] to 280.0 m [200.0; 380.0]; p = 0.003) increased significantly 3 months after the TMVR procedure. Conclusions: TMVR leads to a significant improvement of cognitive function, exercise capacity, and quality of life in patients with chronic heart failure in 3 months follow up and again highlights the benefit of the evermore established TMVR procedure for patients with high operative risk.
