BACKGROUND: Inducible left ventricular outflow tract obstruction (LVOTO) is often encountered in liver transplantation (LT) candidates during cardiac workup. While the impact of LVOTO on adverse cardiovascular hemodynamics is well reported, it is unclear whether it predisposes to perioperative cardiovascular complications. METHODS: Consecutive patients with end-stage liver disease undergoing dobutamine stress echocardiography (DSE) were evaluated at an LT center between 2010 and 2017. Perioperative major adverse cardiovascular events (MACEs) at 30 days and all-cause death were recorded from a prospectively maintained LT database. RESULTS: We evaluated 560 patients who underwent DSE during LT..View full abstract
