Estimation of coronary reserve in left anterior descending and circumflex coronary arteries by regional thermodilution technique.

Single left coronary artery with separate origins of proximal and distal right coronary arteries from left anterior descending and circumflex arteries – a previously undescribed coronary circulation

A single left coronary artery with right coronary artery arising from either left main stem (LMS) or left anterior descending artery (LAD) or circumflex artery (Cx) is an extremely rare coronary anomaly. This is the first report of separate origins of proximal and distal RCA from LAD and circumflex arteries respectively in a patient with a single left coronary artery. This 57 year old patient p...

A rare case of myocardial bridge involving left main, left circumflex, and left anterior descending coronary arteries.

Spontaneous diffuse vasospasm simultaneously found at left main trunk, left anterior descending, left circumflex and right coronary arteries

Coronary artery spasm (CAS) is found not only in Asian but also in white patients. CAS can lead to angina pectoris, myocardial infarction, ventricular arrhythmias and sudden cardiac death. But CAS diagnosis is not necessarily easy, and it also remains highly challenging to therapy and prevention. We present a spontaneous extensive-CAS case with typical clinical features of acute myocardial infa...

Congenital Absence of Left Circumflex Coronary Artery

Congenital absence of left circumflex artery is a rare congenital anomaly of the coronary arteries. The prevalence of the anomaly in different studies ranges from 0.6% to 1.3%. Of these, 80% are benign and asymptomatic and 20% are clinically important. We report a 56-year-old man presented with acute resting chest pain who was diagnosed as having acute anterolateral infarction accompanied by el...

CORONARY BLOOD FLOW Noninvasive Assessment of Coronary Flow Velocity and Coronary Flow Velocity Reserve in the Left Anterior Descending Coronary Artery by Doppler Echocardiography Comparison With Invasive Technique

Objectives. The purpose of this study was to evaluate whether transthoracic Doppler echocardiography (TTDE) can reliably measure coronary flow velocity (CFV) and coronary flow velocity reserve (CFVR) in the left anterior descending coronary artery (LAD) in the clinical setting. Background. Coronary flow velocity measurement has provided useful clinical and physiologic information. Advancement i...
