Insights
Transcatheter aortic valve replacement (TAVR) in patients with cardiac amyloidosis (CA) and aortic stenosis (AS) was associated with improved outcomes. TAVR reduced heart failure readmissions and the composite of mortality and readmissions in this patient group.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Amyloidosis Research
Background:
- The co-occurrence of aortic stenosis (AS) and cardiac amyloidosis (CA) is increasingly recognized.
- The effectiveness of transcatheter aortic valve replacement (TAVR) in patients with CA is not well-established.
Purpose of the Study:
- To evaluate the role and outcomes of TAVR in patients with co-existing CA and AS.
- To assess the impact of TAVR on heart failure readmissions and all-cause mortality in this population.
Main Methods:
- Utilized the National Readmission Dataset (2016-2018) with ICD-10 codes to identify patients with CA and AS.
- Employed Kaplan-Meier curves and multivariate Cox-proportional hazard regression for time-to-event analysis up to 1-year follow-up.
- Primary outcome was a composite of heart failure readmissions and all-cause mortality.
Main Results:
- Of 1,127 CA patients, 8.2% underwent TAVR. TAVR patients were younger and more frequently had coronary artery disease.
- TAVR was associated with a significantly improved primary outcome (8.9% vs 24.4%, HR:0.32, p=0.007).
- TAVR significantly reduced heart failure readmissions (3.8% vs 19.4%, HR:0.22, p=0.008); all-cause mortality was numerically lower but not statistically significant.
Conclusions:
- TAVR is performed in younger CA patients, often at large, teaching hospitals.
- TAVR is associated with a reduced composite outcome of heart failure readmissions and all-cause mortality in patients with cardiac amyloidosis and aortic stenosis.
Background:
Though the co-prevalence of aortic stenosis (AS) and cardiac amyloidosis (CA) is increasingly recognized, the role of transcatheter aortic valve replacement (TAVR) in patients with CA remains unclear.
Methods:
The National Readmission Dataset (2016-18) and ICD-10 codes were used to identify those with CA and AS, in conjunction with TAVR status. The primary outcome was a composite of heart failure (HF) readmissions and all-cause mortality. All outcomes were followed up to 1-year with a median follow up time 172-days. Kaplan-Meier curves and multivariate cox-proportional hazard regression were used for time-to-event analysis.
Results:
Of 1,127 CA patients, 92 (8.2%) had undergone TAVR. Patients with CA who received TAVR were younger and more commonly had coronary artery disease (67.3% vs 44.2%). Teaching (93.6% vs 81.1%) and large hospitals (77.7% vs 59.3%) performed more TAVRs. In multivariate analysis, TAVR was associated with an improved primary outcome (8.9% vs 24.4%, HR:0.32; 95% CI 0.14-0.71, p = 0.007) and with reduced HF readmissions (3.8% vs 19.4%, HR:0.22; 95% CI 0.07-0.68, p = 0.008). All-cause mortality was numerically lower in TAVR patients with CA but did not reach statistical significance.
Conclusions:
CA patients who receive TAVR are younger, and the procedure is more commonly performed at large, teaching hospitals. TAVR was associated with a lower primary composite outcome of HF readmissions and all-cause mortality.
