Doppler Echocardiography at Rest and During Exercise is Valuable in Timing of Aortic Valve Surgery in Male Aortic Regurgitation Patients

Fax number: +46131459492 Aim: To evaluate if left ventricular (LV) systolic function by tissue Doppler Echocardiography (TDE) at rest and exercise preoperatively, could predict postoperative LV function and thereby be useful in timing of aortic valve surgery in patients with severe aortic regurgitation (AR). Methods: In 29 patients (median 59 years, interquartile 39-64) echocardiography, TDE and radionuclide ventriculography were performed pre- and postoperatively, at rest and during supine bicycle exercise. Results: Preoperative EF (ejection fraction) was 62%. Patients formed two groups with basal LV peak systolic velocity (PSV) 5.9 cm/s preoperatively as the cut-off value (Low and High PSV). Preoperatively, Low PSV had lower PSVexercise, EFexercise, atrioventricular plane displacement (AVPD) at rest and upon exercise than High PSV (p<0.005, p<0.05, p<0.00
