Abstract 15967: Does Resting Cardiac Power Index Affect Survival Post Transcatheter Aortic Valve Replacement?

IntroductionCardiac Power Index (CPI) is an integrative hemodynamic measure of cardiac pumping capability, and is the product of the simultaneously measured mean arterial pressure and the cardiac output. It reflects the rate of energy expenditure by the left ventricle to circulate blood. We sought t...

Description
Summary:IntroductionCardiac Power Index (CPI) is an integrative hemodynamic measure of cardiac pumping capability, and is the product of the simultaneously measured mean arterial pressure and the cardiac output. It reflects the rate of energy expenditure by the left ventricle to circulate blood. We sought to assess the association between baseline resting CPI and survival post transcatheter aortic valve replacement (TAVR).MethodsWe retrospectively abstracted data of patients who underwent TAVR in the Mayo Clinic Foundation with follow up data available at 1 year. Baseline demographics, clinical, and echocardiographic data were abstracted. CPI was calculated using the formula, (cardiac output x mean arterial blood pressure)/ (451 x body surface area) W/m. Patients were divided into group 1 CPI
