Chronic AR causes gradual left ventricular volume overload that leads to a series of compensatory changes, including LV enlargement and eccentric hypertrophy. LV dilation occurs through the addition of sarcomeres in series (resulting in longer myocardial fibers), as well as through the rearrangement of myocardial fibers. As a result, the LV becomes larger and more … Continue reading Aortic Incompetence
