RESUMEN
OBJECTIVES: This study evaluates in-hospital, 30-day, and 1-year outcomes post-transcatheter aortic valve replacement (TAVR) in end stage liver disease (ESLD) and/or end stage renal disease (ESRD) compared with patients without these comorbidities. BACKGROUND: TAVR is an alternative to surgical aortic valve replacement in patients with ESLD and ESRD, though current outcomes data are limited. METHODS: We compared 309 patients (N = 29 ESLD and/or ESRD, N = 280 control) age > 18 who underwent transfemoral TAVR from 2014 to 2020 have been compared. RESULTS: Patients with ESLD and ESRD were younger (69.9 ± 11.7 vs. 79.1 ± 9.8, p < .01) with higher STS-PROM scores (8.1 ± 6.7 vs. 4.6 ± 3.9, p < .01). ESRD and ESLD patients had similar rates of in-hospital major vascular complications (3.4% vs. 3.2%, p = .96), major bleeding events (3.4% vs. 3.2%, p = .95), and mortality (0.0% vs. 1.8%, p = .47). Mortality rates were similar at 30-days (3.4% vs. 2.1%, p = .65) with trend to higher mortality at 6-months (6.9% vs. 3.2%, p = .31) and 1-year (15.4% vs. 7.0%, p = .13). Readmission rates were higher in the ESLD and ESRD cohort at 6-months (53.2% vs. 28.6%, p < .01) and 1-year (65.4% vs. 41.0%, p = .02). One patient received dual kidney-liver transplant, 1 patient received a liver transplant, and 7 additional patients were listed for transplant. CONCLUSION: Patients with ESLD and/or ESRD who underwent TAVR had similar mortality at discharge and 30-days compared with patients without these comorbidities with a trend toward increased mortality at 1-year. This study suggests that TAVR is an option for aortic valve disease patients with ESRD and/or ESLD in order to remove cardiac barriers to liver or kidney transplant.

AIMS: Calcified aortic stenosis (AS) and mitral annular calcification (MAC) have certain similar etiology and pathophysiological mechanisms. MAC is frequently encountered in pre-procedural computed tomography (CT) imaging of patients that undergo transcatheter aortic valve replacement (TAVR), but its prognostic implications for these patients have not been thoroughly investigated. This study sought to evaluate the prevalence of MAC among patients with severe AS and to assess the clinical implications of MAC on these patients during and following TAVR. METHODS AND RESULTS: Consecutive patients that underwent TAVR were compared according to the existence of MAC and its severity in pre-TAVR CT scans. From the entire cohort of 761 patients, 49.3% had MAC, and 50.7% did not have MAC. Mild MAC was present in 231 patients (30.4%), moderate MAC in 72 patients (9.5%), and severe MAC in 72 patients (9.5%). Thirty-day mortality and major complications were similar between patients with and without MAC. In a multivariable survival analysis, severe MAC was found to be an independent strong predictor of overall mortality following TAVR (all-cause mortality: hazards ratio [HR] 1.95, 95% confidence interval [CI] 1.24-3.07, P = 0.004; cardiovascular mortality: HR 2.35, 95% CI 1.19-4.66; P = 0.01). Severe MAC was also found to be an independent strong predictor of new permanent pacemaker implantation (PPI) after TAVR (OR 2.83, 95% CI 1.08-7.47; P = 0.03). CONCLUSION: Half of the patients with severe AS evaluated for TAVR were found to have MAC. Severe MAC is associated with increased all-cause and cardiovascular mortality and with conduction abnormalities following TAVR and should be included in future risk stratification models for TAVR.

Few studies have compared the clinical outcomes between valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) with new-generation valves and re-operative surgical aortic valve replacement (Redo-SAVR). We compared the clinical outcomes of patients who underwent ViV-TAVR with those of patients who underwent Redo-SAVR at Cedars-Sinai Medical Center between 2015 and 2021. New-generation valves were used for ViV-TAVR. A propensity score-matched (PSM) analysis was performed to adjust for differences in baseline characteristics. The primary end point was all-cause mortality at 30 days and 2 years. In-hospital procedural and clinical outcomes were also compared between the groups. A total of 256 patients (140 who underwent ViV-TAVR and 116 who underwent Redo-SAVR) were eligible for PSM. In the unmatched cohort, patients in the ViV-TAVR group were older and had more co-morbidities than those in the Redo-SAVR group. After PSM, there were no significant differences in all-cause death between the ViV-TAVR and Redo-SAVR groups at 30 days (3.9% vs 2.6%, p = 0.65) or 2 years (6.5% vs 7.8%, p = 0.75). The incidences of stroke and heart failure rehospitalization were similar at 30 days and 2 years. The cumulative complication rates during hospitalization were significantly lower in the ViV-TAVR group than in the Redo-SAVR group (11.7% vs 28.6% p = 0.015). The long-term outcomes of ViV-TAVR using new-generation valves were similar to those of Redo-SAVR, although ViV-TAVR was associated with lower rates of in-hospital complications.

Objective: To assess the incidence of new adverse coronary events (NACE) following transcatheter aortic valve replacement (TAVR) and valve-in-valve TAVR (ViV-TAVR). Background: ViV-TAVR is an accepted treatment for degenerative prostheses among patients with high surgical-risk. TAVR studies have suggested an increased risk of coronary artery obstruction and flow stasis causing thrombus formation. Whether contemporary ViV-TAVR is associated with higher rate of coronary events compared to TAVR is unknown. Methods: We used data from 1,224 TAVR patients between 2016 and 2021. We propensity-matched patients following ViV-TAVR and TAVR by significant predictors to overcome confounders in patients' baseline characteristics and procedural factors. Results: The matched population included 129 patients in each group. In line with prior reports, there was a higher in-hospital coronary artery obstruction rate with ViV-TAVR (3.1 vs. 1.6%; p = 0.23). Despite this, 2-year cumulative NACE rates were similar between groups (4.7 vs. 6.2%, respectively, p = 0.79), with no difference between its components: myocardial infarction (MI) (p = 0.210), unplanned coronary catheterization (p = 0.477), or coronary artery bypass grafting (CABG) (p = 0.998). Moreover, hypoattenuated leaflets thickening (HALT) at 30-day CT was observed in nearly a quarter of the patients with no difference between groups (23.9 vs. 23.1%, HR 1.02, 95% CI 0.50-1.28, p = 0.872). The progression rate of the coronary artery calcium score (CACS), assessed in a third of patients, was similar between groups (p log-rank = 0.468, 95% CI 0.12-1.24). Low coronary artery height was an unfavorable predictor for in-hospital coronary obstruction and 2-year NACE rate (HR 1.20 and HR 1.25, p = 0.001 and p < 0.0001, respectively). Conclusion: At 2-year follow-up, ViV-TAVR was not associated with a higher rate of myocardial infarction, unplanned catheterization, coronary artery bypass grafting, or hypoattenuated leaflet thickening.
RESUMEN
Background: There is growing evidence of the safety of same-day discharge for low-risk conscious sedated TAVR patients. However, the evidence supporting the safety of early discharge following GA-TAVR with routine transesophageal echocardiography (TEE) is limited. Aims: To assess the safety of early discharge following transcatheter aortic valve replacement (TAVR) using General Anesthesia (GA-TAVR) and identify predictors for patient selection. Materials and methods: We used data from 2,447 TEE-guided GA-TAVR patients performed at Cedars-Sinai between 2016 and 2021. Patients were categorized into three groups based on the discharge time from admission: 24 h, 24-48 h, and >48 h. Predictors for 30-day outcomes (cumulative adverse events and death) were validated on a matched cohort of 24 h vs. >24 h using the bootstrap model. Results: The >48 h group had significantly worse baseline cardiovascular profile, higher surgical risk, low functional status, and higher procedural complications than the 24 h and the 24-48 h groups. The rate of 30-day outcomes was significantly lower in the 24 h than the >48 h but did not differ from the 24-48 h (11.3 vs. 15.5 vs. 11.7%, p = 0.003 and p = 0.71, respectively). Independent poor prognostic factors of 30-day outcomes had a high STS risk of ≥8 (OR 1.90, 95% CI 1.30-2.77, E-value = 3.2, P < 0.001), low left ventricle ejection fraction of <30% (OR 6.0, 95% CI 3.96-9.10, E-value = 11.5, P < 0.001), and life-threatening procedural complications (OR 2.65, 95% CI 1.20-5.89, E-value = 4.7, P = 0.04). Our formulated predictors showed a good discrimination ability for patient selection (AUC: 0.78, 95% CI 0.75-0.81). Conclusion: Discharge within 24 h following GA-TAVR using TEE is safe for selected patients using our proposed validated predictors.
RESUMEN
OBJECTIVES: Aortic valve preparation with balloon aortic valvuloplasty (BAV) has been previously considered mandatory during transcatheter aortic valve implantation (TAVI) procedures. BAV-inherent risks including stroke, conduction abnormalities, and reduced device profile size established the rationale for safe valve deployment without the need for aggressive valve preparation. We investigate the feasibility and safety of performing Sapien 3 (S3; Edwards Lifesciences) balloon-expandable TAVI with moderate or without predilation (PD). METHODS: We examined consecutive patients with severe aortic stenosis who underwent S3-TAVI at our institution. Overall, 119 patients underwent TAVI without PD and 126 with moderate PD (mean valvuloplasty balloon diameter, 15.3 ± 2.1 mm). TAVI endpoints and adverse events were considered according to the Valve Academic Research Consortium (VARC)-2 definitions. RESULTS: Device success for the entire cohort was 98.8%. PD rates were similar between groups. Total fluoroscopy time and amount of contrast used were lower in the no PD group (13 min vs 16.2 min [P<.001] and 71.3 mL vs 81 mL [P=.03], respectively). All-cause mortality up to 30 days was 0% (0/119) in the no PD group vs 1.6% (2/126) in the moderate PD group (P=.49). VARC-2 defined complication rates at 30 days including cerebrovascular accident were similar between groups. Overall, there was no significant difference in survival rate between both groups (hazard ratio, 3.6; 95% confidence interval, 0.80-16.2; P=.09). CONCLUSIONS: Balloon-expandable TAVI using the S3 device with moderate or without balloon PD is feasible and safe. Omission of PD in appropriate cases was associated with reduced fluoroscopy time and total contrast used without affecting procedural success.
