Why the study?
Does catheter ablation of the bypass tract improve cardiac function and symptoms in a patient with type B Wolff-Parkinson-White syndrome and heart failure?
Does catheter ablation of the bypass tract improve cardiac function and symptoms in a patient with type B Wolff-Parkinson-White syndrome and heart failure?
Catheter ablation of a bypass tract can improve cardiac function and symptoms in patients with heart failure exacerbated by asynchronous wall motion from pre-excitation.
May support ablation for dyssynchrony-induced HF in WPW; hypothesis-generating and requires prospective confirmation before practice change.
A 67-year-old man was admitted to hospital for the treatment of exertional dyspnea. He suffered from congestive heart failure due to an old inferior myocardial infarction with type B Wolff-Parkinson-White syndrome. Asynchronous wall motion caused by pre-excitation through a right-side bypass tract caused his cardiac function to deteriorate. Catheter ablation of the bypass tract increased the ejection fraction, and improved his symptoms, prior to surgical revascularization.
