Abstract 18514: Outcomes of Different Mechanical Circulatory Support (MCS) Devices and Transcatheter Aortic Valve Replacement (TAVR): A National Cross-sectional US Experience
Introduction: The data regarding use of different Mechanical Circulatory Support (MCS) devices in TAVR is limited. The present study was performed to analyze the complications and outcomes of different MCS in TAVR.
Methods: The subjects under study were obtained from Nationwide Inpatient Sample (NIS) for the years 2011-12 using ICD-9-CM procedure codes for TAVR and MCS. The use of MCS was divided into Intra-aortic balloon pump (IABP), percutaneous ventricular assist devices (PVADs) including Impella and TandemHeart, Extracorporeal membrane oxygenation (ECMO) and percutaneous cardiopulmonary support and cardiopulmonary bypass (CBP) using ICD-9-CM codes. The incidence of in-hospital mortality and occurrence of procedure related complications were analyzed.
Results: Out of total 1794 TAVR procedures, MCS was utilized in 190 (10.6%) procedures. CBP was the most commonly utilized 136 (71.6%) followed by IABP 36 (18.9%), ECMO 14 (7.4%) and 4 (2.1%). In-hospital mortality was highest with use of IABP (36.6%), followed by ECMO (14.3%), CBP (9.6%) and PVAD (0%) with p-value <0.01. The incidence of complications was similar in IABP and PVAD (100% each) followed by ECMO (85.7%) and CBP (59.4%) with p-value <0.01.
Conclusion: Being retrospective in design, the present study has no information regarding indications and individual patient related variables in which each of the MCS devices used. Overall, CBP was observed as the most extensive used MCS modality with less mortality (9.6%) and least complications (59.4%).
