Isolated right ventricular infarction, often linked to chronic lung disease, presents with varied symptoms and cardiac arrhythmias. Echocardiography is key for diagnosis, with cautious treatment improving prognosis despite potential complications.

Area of Science:

  • Cardiology
  • Internal Medicine

Background:

  • Isolated right ventricular infarction is a distinct clinical entity.
  • Chronic lung disease with right ventricular hypertrophy is a significant risk factor.

Purpose of the Study:

  • To report experience with 18 cases of isolated right ventricular infarction.
  • To review the literature on risk factors, presentation, diagnosis, and management.

Main Methods:

  • Case series review of 18 patients.
  • Literature review.

Main Results:

  • Common symptoms include chest pain, breathlessness, palpitations, or syncope.
  • Arrhythmias like atrial fibrillation and ventricular tachycardia can occur; atrioventricular block is rare.

  • Echocardiography is more reliable than ECG for diagnosis; cautious use of nitrates/diuretics is safe if no hypotension.
  • Conclusions:

    • Isolated right ventricular infarction has diverse presentations and requires specific diagnostic approaches.
    • Management involves careful consideration of hemodynamic status and potential complications.
    • Prognosis is generally good, but risks of sudden collapse exist.
