Abstract [en]

Objective. We aimed to investigate if preoperative left ventricular (LV) function assessed by exercise echocardiography could predict late postoperative LV function in aortic regurgitation (AR) patients and to evaluate how LV long-axis function is affected late after aortic valve surgery. Design. A total of 21 male chronic AR patients, aged 49 (12) years, accepted for surgery were examined preoperatively, 6 months-, and 4 years postoperatively, at rest and during exercise. Besides conventional echocardiographic parameters, the atrioventricular plane displacement (AVPD) by M-mode and peak systolic velocity (s) in the basal LV by color tissue Doppler were measured. Results. Preoperatively EFrest and EFexercise, were 55(7)% and 54(9)%, respectively, and Delta EF 0(8)%. LV dimensions and volumes indexed to BSA had decreased at the 6-month follow-up and were stable at late follow-up. s(rest), s(exercise), AVPD(rest), and AVPD(exercise) were unchanged at both the postoperative examinations (all P >= 0.05). Preoperative EFexercise and AVPD(exercise) showed inverse correlation to late postoperative indexed LV enddiastolic volume (r = -0.68, p < 0.004 and r = -0.86, P < 0.001) and indexed LV endsystolic volume (r = -0.68, P = 0.004 and r = -0.81, P < 0.001), while there was no correlation to preoperative EFrest and AVPD(rest) (all r < 0.2). Conclusions. Preoperative exercise echocardiography can detect AR patients with suboptimal LV remodeling late postoperatively.

Abstract [en]

In patients with severe aortic valve disease, aortic valve intervention is performed when the risk for mortality or morbidity with conservative management is significantly increased. Left ventricular (LV) longitudinal motion decreases before conventional echocardiographic measures such as ejection fraction, are influenced in patients with severe aortic valve disease. This thesis is devoted to the assessment of cardiac function, including ventricular longitudinal motion, by echocardiography before and after aortic valve intervention in patients with chronic severe aortic regurgitation (AR) or severe aortic stenosis (AS).

Patients with chronic AR (n=29) were studied preoperatively, and 6 months and 4 years postoperatively by echocardiography, including tissue Doppler imaging, at rest and during exercise. LV longitudinal function (atrioventricular plane displacement, AVPD, and peak systolic velocity, PSV) decreased postoperatively, and patients with low PSV continued to show reduced longitudinal function 6 months after surgery. Preoperative exercise echocardiographic variables showed a strong correlation to late LV function variables, while preoperative variables obtained at rest were not useful for prediction. Exercise echocardiography and longitudinal LV function could therefore be useful complements in the timing of aortic valve surgery for AR.
