Can S-wave changes in right precordial leads predict hemodynamic severity in patients with aortic stenosis before and after AVR?
Can S-wave changes in right precordial leads predict hemodynamic severity in patients with aortic stenosis before and after AVR?
S-wave changes in right precordial leads may serve as a non-invasive marker to predict critical narrowing of the aortic valve area and guide timely referral for AVR.
May support noninvasive aortic stenosis monitoring; hypothesis-generating and should not yet change practice.
BACKGROUND: was not reported in AS. METHODS: ), PG (between 55 and 75 mm Hg or over 75 mm Hg), and end-diastolic LV dimension (of more or less than 56 mm). We evaluated the impact of S-wave magnitude in right precordial leads before and after AVR in all patients. We followed S-wave changes in electrocardiogram altogether with hemodynamic measurements derived from echocardiography. RESULTS: for dependent variables PG and end-diastolic LV dimension. CONCLUSIONS: S-wave changes in right precordial leads can predict increase in PG and critical narrowing of AVA, suggestive of timely referral for AVR.
