Evaluation of the prevalence and predictors of right ventricular diastolic dysfunction in patients undergoing coronary artery bypass surgery.

Background: With the increase in the number of coronary artery bypass grafting (CABG) surgeries, the concern about complications after it has also increased. RV diastolic dysfunction (RVDD) is one of the post-CABG complications, and in this study, we intend to investigate its frequency and predictors.

Methods: In this cross-sectional study, eighty CABG candidate adult patients were included.

Evaluation of Left Ventricular Longitudinal, Radial, and Circumferential Strains in Subjects with Normal Variations of Coronary Dominance: A Preliminary Comparative Study.

Background: The aim of this study was to evaluate the contractile function of the left ventricular muscles in subjects with normal coronary artery and normal variations of coronary dominance.

Methods: This study was performed on 90 adult subjects with normal results of coronary arteries angiography, echocardiography, and electrocardiography. The participants were categorized into 3 groups of 30 with right-dominant, left-dominant, and codominant variations.

Differentiation of the Left and Right Side Interventricular Septum Function in Healthy Subjects by Vector Velocity Imaging.

Background: The present study aimed to assess and compare regional strain of the right and left sides of interventricular septum in healthy subjects using velocity vector imaging analysis due to the importance of interventricular septum and limited basic information about the exact function of the interventricular septum.

Methods: The present study was conducted on 40 healthy subjects. Echocardiography was performed in the apical 4-chamber view in the left lateral decubitus position.
