Abstract
Despite the importance of assessing RV function in many cardiac conditions, evaluation of RV function remains difficult due to complex geometry of this chamber. The development of new quantitative echocardiographic techniques such as ultrasonic strain & strain rate (SR) imaging, has enhanced the ability to non invasively assessing regional RV function.
Strain representing the relative magnitude of segmental systolic shortening and its temporal derivative, the Strain rate (SR) i.e. the maximal velocity of systolic shortening, is considered as an accurate index of myocardial contractility, It is not dependent on adjacent myocardial motion or heart translation.
Balloon Mitral valvuloplasty is considered the treatment of choice for patient with Rheumatic Mitral stenosis, so assessment of success of this procedure is of great importance.
The aim of this study was to use these strain and strain rate parameters in assessment of RV regional functions immediately and within 3 months after BMV in comparison to preprocedural parameters.
