Abstract 213: Prevalence and Regression of Left Ventricular Hypertrophy by Sokolow-lyon and Cornell Electrocardiogram Voltage Criteria After Transcatheter Aortic Valve Replacement

Background and Hypothesis: Left Ventricular Hypertrophy (LVH) due to critical aortic stenosis is expected in TAVR patients. ECG markers of LVH were associated with a significant increase in all-cause mortality in a large prospective study (ARIC) of the general, middle-aged population. However, the sensitivity of LVH by ECG voltage criteria in patients with severe aortic valve stenosis undergoing trans-catheter aortic valve replacement (TAVR) has not yet been studied. The regression of LVH by ECG voltage criteria after TAVR also has not been evaluated. Methods: A retrospective chart review was conducted in 388 consecutive TAVR patients (57.7% females, transfemoral approach in 59.3%, 77.9% with Sapien valve) without ventricular-paced rhythm. ECG data was collected and analyzed by Sokolow-Lyon and Cornell Voltage criteria. Results were compared to transthoracic echocardiogram. Analyses of variation, correlation, chi-square, and logistic regression were used. The study was approved by the institutional IRB. R...
