Observational StudyQualitative Assessment of Color M-Mode Signals in the Evaluation of Left Ventricular Diastolic Function: A Proof of Concept Study.
Although the most recent American Society of Echocardiography guidelines are a major step forward in echocardiographic evaluation of diastolic function, the ability to differentiate between normal and abnormal function remains challenging. The authors aimed to determine whether qualitative assessments of color M-mode flow displays could be a useful parameter in the evaluation of left ventricular (LV) diastolic dysfunction. ⋯ Qualitative assessment of color M-mode flow displays offers simple and reliable information of potential usefulness in the evaluation of LV diastolic function.

Intraoperative Assessment of Coronary Artery Stenosis by 2D Speckle-Tracking Echocardiography: The Correlation Between Peak Strain Rate During Early Diastole and the Severity of Coronary Artery Stenosis in Patients Undergoing Coronary Artery Bypass Grafting.
The effects of inhalation anesthetics on cardiac function and the low correlation between transthoracic and transesophageal echocardiographic measurements may alter the ability of transesophageal echocardiography-derived strain rate during early diastole to detect coronary artery stenosis in anesthetized patients. The authors assessed the correlation between coronary artery stenosis and strain-based parameters during early diastole in heart failure patients with preserved ejection fraction undergoing coronary artery bypass grafting. ⋯ Strain rate during early diastole significantly correlates with the severity of coronary artery stenosis in anesthetized patients suffering from heart failure with preserved ejection fraction.
