We used one English and one Spanish word like mnemonics in this mindmap RaMP and LoCA (crazy). Focus in this minmap:
- POSTERIOR DESCENDING (RaMP): 80% Right dominance (origins R coronary), and 20% Left dominance (origins L coronary circumflex). Irrigates half posterior interventricular septum.
Q: A cardiac enzyme confirm a Non-ST elevation cardiac infarction. Echocardiogram shows a portion of the left ventricular apex that bulges outward during systole and inward during diastole. What coronary artery is affected in this process?
ReplyDeleteA: Left coronary > Left Anterior descending artery. The motion described is called "paradoxical motion" and it's produced by part of ventricle infarction, the area corresponds to the LAD artery.
Q: A 68-year-old man is admitted to the hospital because of a myocardial infarction after he comes to the emergency department with substernal chest pain. Cardiac catherization shows left circumflex coronary artery occlussion and a left dominant coronary circulation. Which cardiac region is most likely to be involved?
ReplyDeleteA: Lateral left ventricular wall and posterior portion of the septum.
