Overview
Causes
- Acute myocardial infarction involving only the free wall of the right ventricle is a rare event. [1] More commonly, right ventricular infarction is associated with infarction of the inferior wall of the left ventricle, occurring in more than one-third of such cases. [2] [3] [4] [5] [6] [7] [8] [9] [10], even when thrombolytic therapy is given [11]
- Ninety percent of right ventricular infarcts result from occlusion of the proximal right coronary artery.
- Another 5 to 10 percent arise after occlusion of the left anterior descending artery. [12] [13] [14] [15]
