assessment of left atrial function after percutaneous coronary intervention: a doppler-based strain and strain rate study

Do left atrial strain and strain rate reflect intrinsic atrial function, or are they determined by left ventricular function?

BACKGROUND Left atrial (LA) strain (S) and strain rate (SR) are reported as measures of intrinsic function. AIM Since the LA and left ventricle (LV) are connected through the mitral annulus, we investigated: (1) if deformation indices in the LA are mostly predicted by deformation of the LV; (2) if timings of S and SR events are similar in both the LA and LV; and (3) if alteration of S and SR ...

Tissue Doppler, strain, and strain rate echocardiography for the assessment of left and right systolic ventricular function.

Tissue Doppler (TDE), strain, and strain rate echocardiography are emerging real time ultrasound techniques that provide a measure of wall motion. They offer an objective means to quantify global and regional left and right ventricular function and to improve the accuracy and reproducibility of conventional echocardiography studies. Radial and longitudinal ventricular function can be assessed b...

a rare complication of primary percutaneous coronary intervention: left atrial dissection and hematoma

conclusions preoperative echocardiography, applied before elective and emergency percutaneous coronary interventions, plays a key role in detecting many intervention-related complications in the post-intervention period. case presentation a 65-year-old male patient was admitted to the emergency department and acute inferolateral myocardial infarction was diagnosed. the left atrial hematoma as a...

assessment of right ventricular function by tissue doppler, strain and strain rate imaging in patients with left-sided valvular heart disease and pulmonary hypertension

background pulmonary artery hypertension is the presentation of various types of cardiovascular and systematic diseases. there are different kinds of noninvasive methods to determine right ventricular function, pulmonary artery pressure, and effect of pulmonary hypertension on right ventricular function. these methods include the tissue doppler imaging (tdi) of the tricuspid annulus and the lon...
