Key result
Isolated RV branch occlusion during angioplasty is linked to right precordial ST elevations in 9 patients.
Why the study?
Data on the electrocardiographic appearance and angiographically proven cause of isolated right ventricular infarction are scarce due to its rarity and confounding ischemic forces from the left ventricle.
What are the electrocardiographic manifestations of acute isolated right ventricular ischaemia in patients experiencing isolated occlusion of a right ventricular branch during PTCA?

What are the electrocardiographic manifestations of acute isolated right ventricular ischaemia in patients experiencing isolated occlusion of a right ventricular branch during PTCA?
Isolated occlusion of a right ventricular branch during PTCA serves as a clinical model demonstrating that pure right ventricular ischemia causes ST elevations in right precordial leads (V1-V3, V3R, V4R).
May guide ECG recognition of isolated RV ischemia during PTCA; leaves open validation in larger prospective cohorts.
An isolated right ventricular infarction occurs rarely and data on its electrocardiographic appearance and underlying angiographically proven cause are scarce. The electrocardiographic response of acute right ventricular ischaemia is often obscured by the coexisting forces of the ischaemic mass of the inferior wall of the left ventricle when the right coronary artery itself becomes occluded. Percutaneous transluminal coronary angioplasty of the right coronary artery may cause an isolated occlusion of a right ventricular branch. We encountered this phenomenon in nine patients. In all, it led to acute isolated right ventricular ischaemia with ST elevations in the right precordial leads (V1-V3, V3R and V4R) on the electrocardiogram. We conclude that the ECG pattern of pure right ventricular ischaemia can be seen when an isolated occlusion of a large right ventricular branch occurs, for example as a complication of percutaneous transluminal coronary angioplasty.

Bolt et al. (1996) conducted a case report in Isolated right ventricular infarction (n=9). Isolated occlusion of a right ventricular branch was evaluated on ST elevations in the right precordial leads (V1-V3, V3R and V4R). Isolated occlusion of a large right ventricular branch during coronary angioplasty led to acute isolated right ventricular ischaemia with ST elevations in right precordial leads in all 9 patients.
