Aim: The electrocardiographic QT dispersion (QTd), Tpe/QT ratio and Tpeak-Tend (Tpe) interval have been known as ventricular repolarization indices. Neutrophilto- lymphocyte ratio (NLR) is an inflammatory marker that is newly described. Increased QTd, Tpe/QT ratio, inflammation and Tpe interval are associated with ventricular arrhythmia (VA). In patients with severe aortic stenosis (AS), VA has a key role in terms of morbidity and mortality. The present study aimed at examining whether transcatheter aortic valve implantation (TAVI) affects ventricular repolarization indices and NLR.
Material and Methods: Study population consisted of a total of 44 patients undergoing TAVI. Echocardiographic and laboratory parameters of patients were evaluated before TAVI and sixth month after TAVI. Comparioson of electrocardiographic QTd, Tpe/QT ratio, Tpe interval and NLR of the same petients were made before TAVI and sixth month after TAVI.
Results: QT interval, corrected QT interval and heart rate were similar before and after TAVI (p>0.05 for all). There was a statistically significant decrease in QTd (26.0±9.1 vs. 21.3±7.2 ms; p=0.008), Tpe interval (88.43±12.6vs. 78.8±10.1 ms; p
