Right Ventricular Function Assessment in Single LAD lesion Patients Using Strain and Strain Rate Imaging
Abstract
Background.
Strain and strain rate imaging is currently the most popular echocardiographic technique that reveals subclinical myocardial damage, no available data on this imaging method with regard to assessing right ventricular involvement in single LAD lesion. Aim. to evaluate right ventricular regional functions using strain and strain rate imaging tissue Doppler method in patients with single LAD lesion .
.
Methods.
The patient group was composed of 60 patients who had experienced first anterior myocardial infarction and had undergone successful percutaneous coronary intervention for LAD lesion . Twenty patients were …show more content…
Hence earliest recognition of RV dysfunction is warranted but till today it remains a challenging task because of complex structure and asymmetric shape of RV . 2 Doppler Tissue imaging is more sensitive than other echocardiographic modalities in evaluation of ventricular functions.18Earlier studies have depended upon M-Mode, 2- D or pulsed Doppler evaluation. 3,4,5,6 Previous studies using Doppler tissue imaging have selectively evaluated lateral tricuspid annulus alone or in combination with RV lateral wall.7,8
Subclinical RV dysfunction is known in patients with right coronary territory ischemia n results. Right ventricular functions in LV anterior infarction has been subject of several studies but with significant discrepancies in results.3, 7
