Aortic Regurgitation
Pathophysiology of Aortic Regurgitation
In aortic regurgitation, volume overload of the left ventricle (LV) occurs because the LV receives blood regurgitated from the aorta during diastole in addition to blood from the left atrium. the LV does not have time to dilate to accommodate the increased volume, which then causes a rapid increase in left ventricular pressure and subsequently Pulmonary Edema and decreased cardiac output. LV hypertrophy and dilation can gradually occur, so normal left ventricular pressures and cardiac output are maintained. But decompensation eventually develops, ultimately causing Overview of Arrhythmias , LV impairment, and
