The transgastric mid-papillary left ventricular short-axis view images the myocardium supplied by which arteries?

• A. Left anterior descending only
• B. Right coronary only
• C. Left circumflex only
• D. All three major coronary arteries

Answer: (D)

In the transgastric mid-papillary left ventricular short-axis view, the ultrasound plane slices through the middle of the left ventricle and shows walls around its circumference—from anterior to inferior. Those walls receive blood from different coronary arteries: the anterior wall and anterior septum mainly from the left anterior descending, the lateral wall from the left circumflex, and the inferior wall from the right coronary artery (via the posterior descending artery in most people). Because this single view encompasses all these wall regions, it images myocardium supplied by all three major coronary arteries. Dominance can shift the exact territory, but this view typically includes regions fed by each artery, making all three involved.
