N2 - Background: The TandemHeart device (THD) is a pump system that can be deployed percutaneously (PC) or via conventional surgical (CS) cannulation; it is capable of supporting one or both ventricles. It is a versatile system designed for use as a rescue device in acute heart failure and as a bridge to decision in moribund patients. Methods: Retrospective analysis was conducted on all patients who underwent a THD implant; either PC or CS; at our institution. Univariate analysis was done using Fisher's exact and Chi-square tests for categorical variables and Wilcoxon Rank Sum test for continuous ones. Results: 51 adult patients were identified: 10 PC and 41 CS. Mean age was 58.9 ± 12.8 years, and 31% were female. In hospital mortality was 61%. Univariate predictors of death were prolonged support (74% versus 46%, P = .04) and higher lactic acid levels (5.3 ± 4.9 versus 2.3 ± 1.9 mmol/L, P = .012). The length of stay (LOS) for survivors was 59.8 ± 30.0 days. Conclusion: Uni- or bi-ventricular unloading can be successfully achieved using the THD, either trans-thoracically or percutaneously, with an acceptable complication profile.
