Summary
Pulmonary embolism and right ventricular infarction rarely occur together, presenting diagnostic and therapeutic challenges. Echocardiography aided in diagnosing pulmonary hypertension and right ventricular dysfunction in a case of ventricular tachycardia.
Area of Science:
- Cardiology
- Pulmonology
- Critical Care Medicine
Background:
- Pulmonary embolism (PE) can precipitate right ventricular (RV) strain and infarction.
- The concomitant occurrence of PE and RV infarction is uncommon but clinically significant.
Observation:
- A rare case presented with pulmonary embolism and isolated right ventricular anterior wall infarction, leading to ventricular tachycardia.
- Two-dimensional echocardiography revealed pulmonary artery hypertension and regional RV wall motion abnormalities.
Findings:
- Echocardiography effectively diagnosed pulmonary hypertension and RV dysfunction.
- Thrombolytic therapy and dobutamine infusion were beneficial in managing the patient.
Implications:
- This case highlights the diagnostic utility of echocardiography in RV infarction secondary to PE.
- Cautious use of nitrates, fluid infusion, and diuretics is advised in such complex cases.
