Key result
Isolated RV branch occlusion during primary RCA PCI can cause ST elevation in leads V1-V3.
Isolated right ventricular branch occlusion during primary right coronary angioplasty can rarely cause ST segment elevation in anterior precordial leads V1 to V3.
Clinicians should consider isolated RV branch occlusion in anterior STE differentials during RCA PCI; single case leaves incidence and implications open.
It is rare to observe ST elevation in anterior derivations caused by isolated right ventricular branch occlusion. We described the case with acute inferior and right ventricular myocardial infarction (MI) who developed ST segment elevation in precordial leads V(1) to V(3) due to isolated right ventricular branch occlusion during primary right coronary angioplasty.
