Background:
Liver cirrhosis is not included in surgical risk prediction models despite being a significant risk factor associated with high periprocedural morbidity and mortality in patients undergoing cardiac surgery. Limited contemporary data exists assessing the outcomes of transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) in patients with cirrhosis.
Methods:
Patients with cirrhosis who underwent TAVR or SAVR were identified from the Nationwide Readmissions Database. Propensity-score matched analysis was performed to compare the clinical characteristics, in-hospital, and 30-day outcomes between the two groups.
Results:
Between 2016 and 2019, 4047 patients with cirrhosis underwent TAVR (n = 3298) or SAVR (n = 749). TAVR adoption sharply rose, doubling the number of cases performed during the study period. Following propensity matching among 718 patients, the TAVR group consistently exhibited significantly lower rates of in-hospital mortality (2.2 vs. 7.5%; p = 0.002), bleeding (14.5 vs. 52.9%; p < 0.001), vascular complications (1.4 vs. 5%; p = 0.011), hepatorenal syndrome (3.3 vs. 8.9%; p = 0.003), cardiogenic shock (2.8 vs. 7%; p = 0.015), mechanical circulatory support utilization (0.6 vs. 4.7%; p = 0.001), 30-day all-cause readmission rates (10.3 vs. 18.1%; p = 0.005), and 30-day unplanned readmission rates (10 vs. 16.6%; p = 0.015) compared to the SAVR group. The TAVR group had significantly shorter median hospital stays, lower non-home disposition rates, and reduced hospital costs.
Conclusions:
TAVR is associated with significantly lower rates of in-hospital mortality, bleeding, vascular complications, hepatorenal syndrome, cardiogenic shock, mechanical circulatory support utilization, and 30-day readmission rates compared to SAVR and represents a safe therapeutic option for aortic valve replacement in patients with cirrhosis.
