Summary
Isolated right ventricular infarction, rarely diagnosed antemortem, was identified via electrocardiogram. Prompt stenting of the occluded right coronary artery restored blood flow, preventing right ventricular dysfunction.
Area of Science:
- Cardiology
- Cardiac Imaging
- Interventional Cardiology
Background:
- Isolated right ventricular infarction is infrequently diagnosed before death.
- Typical electrocardiogram findings can be misleading, mimicking left ventricular infarction.
Observation:
- A case presented with ST segment elevation across multiple leads (left precordial, right precordial, inferior), simulating anterior and inferior left ventricular infarction.
- Coronary angiography identified a completely occluded right coronary artery as the culprit lesion.
Findings:
- The occluded artery was a nondominant right coronary artery exclusively supplying the right ventricle.
- Primary stenting successfully restored coronary blood flow, leading to rapid normalization of ST segments.
- Despite significant right ventricular wall motion abnormalities, no subsequent right ventricular dysfunction occurred.
Implications:
- This case highlights the importance of considering isolated right ventricular infarction in differential diagnoses.
- Early diagnosis and intervention, such as primary stenting, can prevent adverse outcomes like right ventricular dysfunction.
- Further research into antemortem diagnosis and management of this rare condition is warranted.
