Rare cardiac complications after pericardiocentesis, including cardiogenic shock from right ventricular (RV) dysfunction, require prompt recognition. Early diagnosis and treatment of RV and tricuspid valve dysfunction are crucial for patient recovery.
Area of Science:
- Cardiology
- Critical Care Medicine
Background:
- Pericardiocentesis is a procedure to treat cardiac tamponade or diagnose pericardial effusion.
- Right ventricular (RV) dysfunction leading to cardiogenic shock is a rare but serious complication post-pericardiocentesis.
Observation:
- An 82-year-old male experienced cardiopulmonary arrest 12 hours after pericardiocentesis.
- Transthoracic echocardiography revealed significant RV and tricuspid valve dysfunction with impaired closure and severe tricuspid regurgitation.
Findings:
- The patient's hemodynamic parameters gradually improved with high-dose inotropic drug therapy.
- Follow-up echocardiography demonstrated improved RV and tricuspid valve function, reducing tricuspid regurgitation.
Implications:
- Right ventricular and tricuspid valve dysfunction should be recognized as critical complications following pericardiocentesis.
- Physicians must monitor not only drainage volume but also underlying RV function and valve integrity.
