Intraventricular dyssynchrony

WebGlobally, cardiovascular disease (CVD) is the leading cause of mortality. Coronary artery disease (CAD) is one of the most prevalent types of CVD and annually accounts for around half of all CVD deaths. Therefore, CAD is one of the main contributors to massive health, and health-economic, burdens. A major factor in the morbidity and mortality of CAD is … WebApr 16, 2024 · Background: Right ventricular (RV) intraventricular mechanical dyssynchrony detected by two-dimensional speckle tracking echocardiography (2D-STE) has been reported to be correlated with a decrease in RV contractile efficiency in pulmonary hypertension (PH) patients, while little attention has been paid to biventricular …

WebBax and colleagues defined dyssynchrony as the maximum difference in TPSV between the basal anterior, inferior, septal, or lateral ventricular walls. 15 A value of 65ms was used as a cut-off with a sensitivity and specificity of 80% for predicting an improvement in NYHA classification and ≥25% increase in six-minute walking distance with CRT. WebSignificant intraventricular dyssynchrony is more widely observed in these patients. With receiver operator characteristic curve analyses, both OWD and ASPWD demonstrated usefulness in predicting response to CRT in narrow QRS patients with a cut-off value of 75 and 107 ms, respectively.
