Non-invasive left ventricle strain-volume-pressure loops in asymptomatic patients with significant aortic regurgitation: potential to improve prediction of optimal timing for aortic valve surgery
Severe aortic regurgitation (AR) causes left ventricular (LV) pressure and volume overload with irreversible myocardial damage, which often occurs before meeting the aortic valve surgery indication (AVSi) per guidelines. Developing cost-effective imaging markers to identify the initial effects of pressure-volume...
