Diagnosis of coronary sinus diverticulum in Wolff-Parkinson-White syndrome using coronary angiography
Insights
Wolff-Parkinson-White Syndrome with posteroseptal bypass tracts may involve coronary sinus diverticula. Preoperative angiography is suggested to identify these diverticula, potentially reducing surgical and ablation risks.
Area of Science:
- Cardiology
- Cardiac Electrophysiology
- Interventional Cardiology
Background:
- Wolff-Parkinson-White Syndrome (WPW) is associated with accessory pathways that can cause arrhythmias.
- Posteroseptal accessory pathways are a specific type of pathway found in WPW.
- Coronary sinus diverticula are rare congenital abnormalities that can complicate cardiac procedures.
Observation:
- The presence of a coronary sinus diverticulum can complicate surgical interventions for arrhythmias.
- These diverticula may increase risks associated with catheter ablation procedures.
- A case of Wolff-Parkinson-White Syndrome with a posteroseptal bypass tract and a coronary sinus diverticulum is presented.
Findings:
- Preoperative diagnosis of a coronary sinus diverticulum was achieved using late-phase coronary angiography.
- This imaging technique identified the anatomical anomaly before intervention.
Implications:
- Angiography should be considered for patients with posteroseptal bypass tracts before cardiac surgery or ablation.
- Early identification of coronary sinus diverticula can help mitigate procedural risks.
- This approach may improve patient safety in managing complex cardiac arrhythmias.
Abstract:
The entity of Wolff-Parkinson-White Syndrome and coronary sinus diverticula when the bypass tract is posteroseptal in location has been described recently. The presence of this diverticulum may complicate arrhythmia surgery and could potentially add to the risk of catheter ablation. We describe a case of Wolff-Parkinson-White Syndrome in which the diagnosis of a coronary sinus diverticulum was made preoperatively using late-phase coronary angiography and suggest angiography be considered in patients with posteroseptal bypass tracts prior to surgery or catheter ablation.
