Insights
Central venous catheter (CVC) placement can lead to rare but serious tricuspid valve endocarditis. Early recognition and surgical intervention are crucial for managing this complication.
Area of Science:
- Cardiology
- Infectious Diseases
- Medical Devices
Background:
- Central venous catheters (CVCs) are essential for hemodynamic monitoring, drug delivery, and dialysis.
- CVC placement is common, but complications can arise, including rare but severe infectious endocarditis.
- Tricuspid valve endocarditis is a serious CVC complication with high morbidity and mortality.
Purpose of the Study:
- To report a case of tricuspid valve endocarditis secondary to CVC placement.
- To highlight the potential for guide wire or CVC injury to predispose to endocarditis.
- To emphasize the need for surgical management in such cases.
Main Methods:
- Case report detailing a patient with CVC placement.
- Review of potential mechanisms of CVC-related tricuspid valve injury.
- Description of surgical intervention for tricuspid valve endocarditis.
Main Results:
- The patient developed tricuspid valve endocarditis, likely due to guide wire or CVC injury.
- Open heart surgery was required for vegetectomy and tricuspid valve repair.
- Successful surgical outcome was achieved.
Conclusions:
- Tricuspid valve injury from CVC insertion can lead to infectious endocarditis.
- Prompt surgical intervention is necessary for managing CVC-related tricuspid valve endocarditis.
- This case underscores the importance of careful CVC technique to prevent severe complications.
Abstract:
A central venous catheter (CVC) is inserted for measurement of haemodynamic variables, delivery of nutritional supplements and drugs and access for haemodialysis and haemofiltration. Catheterization and maintenance are common practices and there is more to the technique than routine placement as evident when a procedure-related complication occurs. More than 15% of the patients who receive CVC placement have some complications and infectious endocarditis involving the tricuspid valve is a rare and serious complication with high morbidity and mortality. Overenthusiastic and deep insertion of the guide wire and forceful injection through the CVC may lead to injury of the tricuspid valve and predispose to bacterial deposition and endocarditis. We report a case of tricuspid valve endocarditis, probably secondary to injury of the anterior tricuspid leaflet by the guide wire or the CVC that required open heart surgery with vegetectomy and repair of the tricuspid valve.
