Abstract
The global time to peak systolic strain compared before the closure of the duct and in the 1-month follow up, it increased to a mean of 0.765 sec. +/- 0.31. This increase was statistically significant.
The heart rate showed sustained significant negative correlation with the global time to peak systolic strain in the pre, 1-day and 1-month post PDA closure.
The study concluded that speckle tracking echocardiography could be used to detect subtle changes in LV deformation and the effect of pressure overload on regional LV function in patients with patent ductus arteriosus.
Time to peak systolic strain is an understudied parameter that needs further evaluation to provide a better understanding regarding its role in myocardial function assessment.
