This is an angiogram of a left coronary artery (LCA). The circumflex artery, labelled CX, is dominant, meaning that it connects to the posterior descending artery and perfuses the posterior and inferior walls of the left ventricle. Approximately 15-18% of the population has a dominant circumflex artery. In about 80-85% of people, the right coronary artery (RCA), perfuses the inferior wall.
This image is taken from the patient featured in our Teaching Series, AWMI. This shot shows the left anterior descending artery just after a stent has been placed and blood flow returned. There had been a 100% occlusion prior to the angioplasty. The circumflex and obtuse marginal arteries show evidence of severe coronary artery disease and multiple partial obstructions, and were also repaired.
This 88-year-old woman was brought to the Emergency Department in cardiogenic shock. Very little is known of her past medical history, but it was relayed to the EMS responders that she had been ill for about four days, when she became much worse.
This week's ECG for your collection was kindly donated by Dr. Stasinos Theodorou, interventional cardiologist with the Limassol Cardiology Practice in Cyprus. It offers a wonderful teaching opportunity, and illustrates how valuable an ECG can be in locating a lesion during an M.I. Dr.
An angiogram of the left coronary artery of a patient with multi-vessle coronary artery disease. Pacemaker electrodes are seen in the right atrium and right ventricle. A Swan Ganz catheter is also visible, with balloon inflated.
This ECG was taken from a 66-year-old woman who presented to the emergency department complaining of chest pain and shortness of breath. She attributed her symptoms to her COPD, but stated that her aerosol treatment had not helped. She waited for some time before deciding to go to the hospital, then drove herself. In the emergency department, she had blood drawn, an I.V. started, and an aerosol treatment of albuterol. She was then taken to the radiology dept.
