Comparison of Outcomes of Balloon Aortic Valvuloplasty Plus Percutaneous Coronary Intervention Versus Percutaneous Aortic Balloon Valvuloplasty Alone During the Same Hospitalization in the United States

摘要

The use of percutaneous aortic balloon balvotomy (PABV) in high surgical risk patients has resurged because of development of less invasive endovascular therapies. We compared outcomes of concomitant PABV and percutaneous coronary intervention (PCI) with PABV alone during same hospitalization using nation's largest hospitalization database. We identified patients and determined time trends using the International Classification of Diseases, Ninth Revision, Clinical Modification, procedure code for valvulotomy from Nationwide Inpatient Sample database 1998 to 2010. Only patients >60 years with aortic stenosis were included. Primary outcome included in-hospital mortality, and secondary outcomes included procedural complications, length of stay (LOS), and cost of hospitalization. Total 2,127 PABV procedures were identified, with 247 in PABV + PCI group and 1,880 in the PABV group. Utilization rate of concomitant PABV + PCI during same hospitalization increased by 225% from 5.1% in 1998 to 1999 to 16.6% in 2009 to 2010 (p <0.001). Overall in-hospital mortality rate and complication rates in PABV + PCI group were similar to that of PABV group (10.3% vs 10.5% and 23.4% vs 24.7%, respectively). PABV + PCI group had similar LOS but higher hospitalization cost (median [interquartile range] $30,089 [$21,925 to $48,267] versus $18,421 [$11,482 to $32,215], p <0.001) in comparison with the PABV group. Unstable condition, occurrence of any complication, and weekend admission were the main predictors of increased LOS and cost of hospital admission. Concomitant PCI and PABV during the same hospitalization are not associated with change in in-hospital mortality, complications rate, or LOS compared with PABV alone; however, it increases the cost of hospitalization.
