In this issue of JASE, Fijalkowski et al.(1) describe an improvement in myocardial reflectivity induced by aortic valve replacement (AVR) in severe aortic stenosis (AS), using integrated backscatter (IBS) analysis, one of the ultrasonic methods for tissue characterization currently available. Furthermore, they found that IBS parameters have a predictive value for left ventricular (LV) reverse remodeling after AVR. The study population consisted of 58 patients with severe AS who were followed up for an average of 18 +/- 5 months after AVR. The authors observed a significant reduction of LV mass index and a significant increase in IBS mean cyclic variation and a decrease in the absolute end-diastole IBS intensity after AVR, showing an improvement of ultrasonic myocardial properties after AVR. They also demonstrated that preoperative analysis of IBS parameters might provide additional information to predict LV reverse remodeling in patients with a mean duration of 1.5 years of follow-up after AVR.

Abstract
In this issue of JASE, Fijalkowski et al.(1) describe an improvement in myocardial reflectivity induced by aortic valve replacement (AVR) in severe aortic stenosis (AS), using integrated backscatter (IBS) analysis, one of the ultrasonic methods for tissue characterization currently available. Furthermore, they found that IBS parameters have a predictive value for left ventricular (LV) reverse remodeling after AVR. The study population consisted of 58 patients with severe AS who were followed up for an average of 18 +/- 5 months after AVR. The authors observed a significant reduction of LV mass index and a significant increase in IBS mean cyclic variation and a decrease in the absolute end-diastole IBS intensity after AVR, showing an improvement of ultrasonic myocardial properties after AVR. They also demonstrated that preoperative analysis of IBS parameters might provide additional information to predict LV reverse remodeling in patients with a mean duration of 1.5 years of follow-up after AVR.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
