Knowledge concerning phasic coronary blood flow is based primarily on measurements obtained from epicardial coronary arteries, which, in part, function as capacitors. If present, epicardial capacitance effects could obscure the dynamic nature of phasic intramyocardial perfusion. To analyze this effect of epicardial capacitance, we simultaneously measured coronary blood flow velocity in an epica...

Abstract Background Index of microcirculatory resistance (IMR) has been used as a clinical measure microvascular function. Transthoracic Doppler echocardiography (TDE) can provide information on the functional status coronary artery circulation. This study aims to assess diagnostic value left-anterior-descending (LAD) flow velocity by TDE for dysfunction. Methods Consecutive patients who were s...

Case History: A 62-year-old male with a history of hypertension and coronary artery disease with prior stenting to the left circumflex artery presented with chest pain. Echocardiography on admission demonstrated a globally reduced ejection fraction of 10% to 15% with regional wall-motion abnormality consistent with prior anterior and inferolateral infarction. End-diastolic volume of the left ve...

a 45- year old man with a history of aortic valve replacement presented with acute chest pain which was diagnosed to be anterior wall myocardial infarction. he received thrombolytic therapy with streptokinase. echocardiography and fluoroscopy showed normally functioning ball and cage aortic prosthesis. coronary arteriography showed globular filling defect in midportion of left anterior descendi...

Certain subsets of high-risk mitral valve patients are not suitable candidates for transcatheter therapies. The objective of this report is to present a young patient with combined mitral valve and coronary artery disease to illustrate these challenges.In this report, we present a 47-year-old man with longstanding HIV infection who was referred with severe mitral regurgitation (MR) and profound...

Coronary stent loss is a rare but serious complication during interventional cardiology. This complication occurs not only in the intracoronary area but also in the extracoronary area, such as the aortic root or the left ventricle. An 83-year-old man with stable angina had a stent inserted into a heavy calcific left anterior descending artery. The stent was lost twice during the procedure. The ...

  Transient ischemic left ventricular dilation (TID) is a marker of severe and extensive coronary artery disease as well as an increased risk of adverse outcomes. The patients with more severe and extensive ischemia, multivessel-type of perfusion abnormality as well as patients with left anterior descending artery (LAD) territory perfusion abnormality have more probab...

A 59 year old man was admitted to hospital with a non-transmural anterior myocardial infarction. Recurrent angina pectoris eight days after the initial infarction was investigated by cardiac catheterisation, which showed moderate anterior hypokinesis and proximal occlusion of the left anterior descending coronary artery. The distal part of this vessel was opacified via collaterals from the righ...

INTRODUCTION AND OBJECTIVE Patients with lesions of the proximal left anterior descending coronary artery are a special high-risk group. In the present study we analyzed the efficacy and safety of coronary stenting in such lesions and the factors related to a less favorable prognosis in long-term follow-up. METHODS Ninety-eight consecutive patients with severe left anterior descending artery ...
