LCx occlusion linked to RV and inferior MI in patients with absent or hypoplastic RCA.
Highlights a rare anatomical variant where left circumflex occlusion can cause right ventricular infarction due to an absent or hypoplastic right coronary artery.
Consider anomalous coronary anatomy in right ventricular infarction; leaves open prevalence and management implications.
