Impact of Atrial Fibrillation on Patients Undergoing Transcatheter Aortic Valve Implantation (TAVI): The K-TAVI Registry.

ABSTRACT:

Purpose

The incidence and prognostic implications of atrial fibrillation (AF) in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) are controversial, especially for Korean patients. Furthermore, the pattern of antithrombotic therapy for these patients is unknown. The present study sought to identify the impact of AF on Korean patients undergoing TAVI and demonstrate the status of antithrombotic therapy for these patients.

Materials and methods

A total of 660 patients who underwent TAVI for severe AS were recruited from the nationwide K-TAVI registry in Korea. The enrolled patients were stratified into sinus rhythm (SR) and AF groups. The primary endpoint was all-cause death at 1-year.

Results

AF was recorded in 135 patients [pre-existing AF 108 (16.4%) and new-onset AF 27 (4.1%)]. The rate of all-cause death at 1 year was significantly higher in patients with AF than in those with SR [16.2% vs. 6.4%, adjusted hazard ratio (HR): 2.207, 95% confidence interval (CI): 1.182-4.120, p=0.013], regardless of the onset timing of AF. The rate of new pacemaker insertion at 1 year was also significantly higher in patients with AF than in those with SR (14.0% vs. 5.5%, adjusted HR: 3.137, 95%CI: 1.621-6.071, p=0.001). Among AF patients, substantial number of patients received the combination of multiple antithrombotic agents (77.8%), and the most common combination was that of aspirin and clopidogrel (38.1%).

Conclusion

AF was an independent predictor of 1-year mortality and new pacemaker insertion in Korean patients undergoing TAVI.

Project description:AimsMitral stenosis (MS) occasionally coexists with aortic stenosis (AS). Limited data are available regarding the functional class and clinical outcomes of patients who undergo transcatheter aortic valve implantation (TAVI) for combined AS and MS. This study compared the clinical outcomes in patients with and without MS who underwent TAVI for severe AS and assessed the impact of mitral annulus calcification (MAC) severity, transmitral gradient (TMG) and mitral valve area (MVA) on outcomes in patients with combined AS and MS.MethodsWe investigated patients in the OCEAN-TAVI registry who underwent TAVI. MS was defined as an MVA ≤ 1.5 cm2 or TMG ≥ 5 mmHg. The composite of all-cause death and admission for heart failure was compared between patients with and without MS. The impact of MAC, TMG and MVA on outcomes was assessed in patients with combined AS and MS.ResultsWe identified 106 patients with MS (MAC 84%; TMG 6.4 ± 2.6 mmHg; MVA 1.10 ± 0.31 cm2) and 6570 without MS as controls. The MS group was older (85 ± 5 vs. 84 ± 5 years, P = 0.033), more of women (85 vs. 67%, P < 0.01), and had a higher risk of surgery (the Society of Thoracic Surgeons Mortality Score 8.7 ± 5.1 vs. 7.6 ± 5.9, P = 0.047) than the controls. In the MS group, the New York Heart Association Functional Class was 3 or 4 in 56% of the patients at baseline and 6% at 1 year after TAVI. Thirty-day mortality (2.8% vs. 1.3%, P = 0.18) and early composite outcomes (17% vs. 15%, P = 0.56) were comparable between patients with and without MS. During a median follow-up of 2.1 years, the presence of MS was associated with a higher incidence of adverse events compared with controls (adjusted hazard ratio [HR] 1.84; 95% confidence interval [CI] 1.34-2.51, P < 0.01), even on propensity score matched analysis (adjusted HR 1.91; 95% CI 1.14-3.22, P < 0.01). Moderate or severe MAC contributed to increased risk of adverse events in patients with MS (adjusted HR 2.89; 95% CI 1.20-6.99, P = 0.018), but TMG and MVA did not.ConclusionsIn patients undergoing TAVI for severe AS, those with moderate or severe MS experienced worse outcomes after TAVI compared with those without MS. Patients with combined AS and MS sustained symptom improvement at 1-year post-TAVI. MAC severity was a useful predictor of adverse events compared with MS haemodynamics such as TMG and MVA in patients with combined AS and MS.

Project description:BackgroundA substantial number of patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) experience adverse events after TAVI, with health care expenditure. We aimed to investigate cardiac remodeling and long-term outcomes in diabetic patients with severe AS, left ventricular ejection fraction (LVEF) < 50%, and extra-valvular cardiac damage (EVCD) undergoing TAVI treated with sodium-glucose cotransporter-2 inhibitors (SGLT2i) versus other glucose-lowering strategies (no-SGLT2i users).MethodsMulticenter international registry of consecutive diabetic patients with severe AS, LVEF < 50%, and EVCD undergoing TAVI. Based on glucose-lowering therapy at hospital discharge, patients were stratified in SGLT2i versus no-SGLT2i users. The primary endpoint was a composite of all-cause death and heart failure (HF)-hospitalization (major adverse cardiovascular events, MACE) at 2-year follow-up. Secondary outcomes included all-cause death, cardiovascular death, and HF hospitalization.ResultsThe study population included 311 patients, among which 24% were SGLT2i users. Within 1-year after TAVI, SGLT2i users experienced a higher rate of LV recovery (p = 0.032), especially those with baseline LVEF ≤ 30% (p = 0.026), despite the lower baseline LVEF. Patients not treated with SGLT2i were more likely to progress to a worse EVCD stage over time (p = 0.018). At 2-year follow-up, SGLT2i use was associated with a lower rate of MACE, all-cause death, and HF hospitalization (p < 0.01 for all). After adjusting for confounding factors, the use of SGLT2i emerged as an independent predictor of reduced MACE (HR = 0.45; 95% CI 0.17-0.75; p = 0.007), all-cause death (HR = 0.51; 95% CI 0.25-0.98; p = 0.042) and HF-hospitalization (HR = 0.40; 95% CI 0.27-0.62; p = 0.004).ConclusionsIn diabetic patients with severe AS, LVEF < 50%, and EVCD undergoing TAVI, the use of SGLT2i was associated with a more favorable cardiac remodeling and a reduced risk of MACE at 2-year follow-up.

Project description:AimTranscatheter aortic valve implantation (TAVI) is a mainstay in the management of severe aortic stenosis in patients with intermediate to prohibitive surgical risk. When a single TAVI device fails and cannot be retrieved, TAVI-in-TAVI must be performed acutely, but outcomes of bailout TAVI-in-TAVI have been incompletely appraised. We aimed at analyzing patient, procedural and outcome features of patients undergoing bailout TAVI-in-TAVI in a multicenter registry.MethodsDetails of patients undergoing bailout TAVI-in-TAVI, performed acutely or within 24 h of index TAVI, in 6 international high-volume institutions, were collected. For every case provided, 2 same-week consecutive controls (prior TAVI, and subsequent TAVI) were provided. Outcomes of interest were procedural and long-term events, including death, myocardial infarction, stroke, access site complication, major bleeding, and reintervention, and their composite (i.e. major adverse events [MAE]).ResultsA total of 106 patients undergoing bailout TAVI-in-TAVI were included, as well as 212 controls, for a total of 318 individuals. Bailout TAVI-in-TAVI was less common in younger patients, those with higher body mass index, or treated with Portico/Navitor or Sapien devices (all p < 0.05). Bailout TAVI-in-TAVI was associated with higher in-hospital rates of death, emergency surgery, MAE, and permanent pacemaker implantation (all p < 0.05). Long-term follow-up showed that bailout TAVI-in-TAVI was associated with higher rates of death and MAE (both < 0.05). Similar findings were obtained at adjusted analyses (all p < 0.05). However, censoring early events, outlook was not significantly different when comparing the two groups (p = 0.897 for death, and p = 0.645 for MAE).ConclusionsBail-out TAVI-in-TAVI is associated with significant early and long-term mortality and morbidity. Thus, meticulous preprocedural planning and sophisticated intraprocedural techniques are of paramount importance to avoid these emergency procedures.
