Direct visualization of a significant stenosis of the right coronary artery by transthoracic echocardiography. A case report
Non-invasive imaging of coronary arteries by transthoracic echocardiography is an emerging diagnostic tool to study the left main (LM), left descending artery (LAD), circumflex (Cx) and right coronary artery (RCA). Impaired coronary circulation can be assessed by measuring coronary velocity flow reserve (CVFR) by transthoracic Doppler echocardiography. Coronary artery stenoses can be identified...
متن کاملNew noninvasive method for coronary flow reserve assessment: contrast-enhanced transthoracic second harmonic echo Doppler.
BACKGROUND We tested the hypothesis that blood flow velocity could be recorded in the left anterior descending coronary artery (LAD) during transthoracic echocardiography by use of second harmonic echo Doppler modality along with contrast enhancement (intravenous Levovist) at rest and after pharmacologically induced maximal vasodilation to assess coronary flow reserve (CFR) with a totally nonin...
متن کاملNon-invasive estimation of cardiac wall stress by using tissue doppler-echocardiography ultrasound images: People with coronary artery stenosis
In this study, a method for non-invasive estimation of stress on the heart wall in the diastole phase is presented using ultrasound echocardiography and tissue Doppler imaging. The aim of this study was to evaluate the stress on the heart wall as a pre-diagnosis to identify people with coronary artery stenosis. 29 patients with stenosis of more than 70%, 30 patients with stenosis of 50 to 7...
متن کاملTransthoracic coronary flow reserve and dobutamine derived myocardial function: a 6-month evaluation after successful coronary angioplasty
After percutaneous transluminal coronary angioplasty (PTCA), stress-echocardiography and gated single photon emission computerized tomography (g-SPECT) are usually performed but both tools have technical limitations. The present study evaluated results of PTCA of left anterior descending artery (LAD) six months after PTCA, by combining transthoracic Doppler coronary flow reserve (CFR) and color...
متن کاملAssessment of internal mammary artery and saphenous vein graft patency and flow reserve using transthoracic Doppler echocardiography.
OBJECTIVE To investigate transthoracic Doppler echocardiography in the identification of coronary artery bypass graft (CABG) flow for assessing graft patency. DESIGN The initial study group comprised 45 consecutive patients with previous CABG undergoing elective cardiac catheterisation for recurrent ischaemia. The Doppler variables best correlated with angiographic graft patency were then tes...
