Cardiopulmonary Bypass Transiently Inhibits Intraventricular Vortex Ring Formation in Patients Undergoing Coronary Artery Bypass Graft Surgery

The results indicated that CPB transiently attenuate VFT in patients with normal preoperative LV systolic and diastolic function undergoing CABG surgery. These data suggest that CPB adversely affects diastolic transmitral flow efficiency by reducing intraventricular vortex ring formation in vivo.
