Severe right ventricular and tricuspid valve dysfunction after pericardiocentesis

We report a case of an 82-year-old man who suddenly suffered cardiopulmonary arrest 12  h after pericardiocentesis. A transthoracic echocardiogram showed remarkable RV dysfunction and tricuspid valve dysfunction. Tricuspid valve closure was severely impaired, and the tricuspid regurgitation signal showed laminar flow with an early peak. However, after treatment with high-dose inotrop ic drugs, hemodynamic parameters gradually recovered. A transthoracic echocardiogram performed 24 h later showed improved motion of the RV and the tricuspid valve, resulting in a reduction in tricuspid regurgitation. RV and tricuspid valve dysfunction after pericardiocentesis needs to be recognized as a critical complication. Physicians also need to pay attention to not only the amount of drainage but also underlying RV dysfunction.
