Which artery is implicated in an inferior-right ventricular infarction?

• A. Left anterior descending artery
• B. Circumflex artery
• C. Right coronary artery
• D. Left marginal artery

Answer: (C)

The right coronary artery is the primary artery involved in supplying blood to the inferior wall of the heart, including the right ventricle. In cases of an inferior-right ventricular infarction, it is typically due to occlusion or significant narrowing of this artery. The right coronary artery provides blood flow to the inferior portion of the heart, and when it is compromised, it can lead to ischemia or infarction in the areas it supplies. In a right dominant coronary system, which is common in the majority of individuals, the right coronary artery also gives rise to the posterior descending artery. This artery is crucial for supplying the inferior part of the heart, making it pivotal in inferior infarctions. Understanding the role of the right coronary artery is essential for recognizing the presentation and management of inferior-right ventricular infarctions, including the implications for hemodynamics, such as potential right ventricular failure, which can occur with inferior wall infarctions when the right coronary artery is affected.
