Summary
This study details the successful anticoagulation treatment of a large right atrial thrombus in a patient with Wolff-Parkinson-White Syndrome after radiofrequency ablation. The case also illustrates T-wave memory, a common post-ablation phenomenon.
Area of Science:
- Cardiology
- Electrophysiology
- Thrombosis Research
Background:
- Wolff-Parkinson-White (WPW) Syndrome is a cardiac condition requiring intervention, often radiofrequency ablation (RFA).
- Radiofrequency ablation (RFA) for accessory pathways can carry risks, including thrombus formation.
- Atrial thrombus is a serious complication that can lead to embolic events.
Observation:
- A large, free-floating right atrial thrombus was identified in a 24-year-old patient post-RFA for WPW Syndrome.
- The patient also exhibited "T-wave memory," a known phenomenon following RFA in WPW Syndrome patients.
Findings:
- Successful treatment of the large right atrial thrombus was achieved using anticoagulation therapy with Heparin and Phenprocoumon.
- The case demonstrates the clinical presentation and management of a rare but significant complication post-RFA.
Implications:
- This case highlights the importance of monitoring for and managing atrial thrombus formation after RFA in WPW Syndrome.
- Anticoagulation therapy can be effective in treating significant atrial thrombi post-cardiac ablation.
- Understanding "T-wave memory" is crucial for interpreting ECG findings in patients undergoing RFA for WPW Syndrome.
