This goal of this study is to analyze images of the right ventricle taken via 3D transesophageal echocardiography (TEE) during left ventricular assist device (LVAD) implantation.
There are two chambers in the heart known as ventricles which are responsible for pumping blood to both the lungs and the rest of the body. The right ventricle pumps blood to the lungs for oxygenation. The left ventricle then delivers this oxygenated blood to the organs in the body. When the left ventricle is damaged enough that it is not able to effectively pump blood then it may be necessary to assist it with a mechanical pump. This pump is called left ventricular assist device (LVAD).
Left ventricular assist devices (LVADs) improve quality of life and survival in patients with end stage heart failure. However, right ventricular (RV) failure is common in 20-50% of LVAD recipients and is associated with perioperative complications.
Traditional two-dimensional ultrasound views of the right ventricle may not accurately depict how well or poorly the right ventricle is working. Three-dimensional (3D) images can overcome the limitations of two-dimensional images and are becoming more commonplace. This goal of this study is to analyze images of the right ventricle taken via 3D transesophageal echocardiography (TEE) during the LVAD implantation to help predict which patients are at higher risk of right ventricular failure within 14 days of the procedure.
