Natural History
Wolff-Parkinson-White syndrome can be either asymptomatic or symptomatic.As it is difficult to evaluate asymptomatic patients, most information about the natural history of these patients has been taken from symptomatic patients.[1] Patients with WPW pattern can remain asymptomatic through all their lives, nearly 65% of adolescents and 40% of adults present ECG changes but remain asymptomatic.[2]
Complications
- Complications Wolff-Parkinson-White syndrome are a consequence of symptomatic tachycardias and can occur at any age.
- Most patients with this condition never experience symptoms associated with the accessory pathway.
- Symptomatic patients are at risk of the following complication include:[3]
- Reduced blood pressure and syncope
- Tachycaria induced cardiomayopathy
- Cardiac arrest
- Ventricular fibrillation
- Sudden cardiac death
- Complications of ablation
- Side effects of medications
- Cause of SCD in WPW syndrome is the rapid conduction of atrial fibrillation to the ventricles via the accessory bypass tract causing ventricular fibrillation.
- WPW paitnents at high risk of sudden cardiac death are the ones with a short interval between ventricular rates less than 250 milliseconds. [4]
Prognosis
- Asymptomatic patients and appropriately treated WPW syndrome have an excellent prognosis.
- Catheter ablation (radiofrequency ablation) has a success rate between 95 - 98%, which varies depending on the location and number of accessory pathways.
- Successful ablation prevents future supraventricular tachyarrhythmia.
- Factors associated with a worse prognosis include:
- A family history of sudden cardiac death
- Symptomatic tachyarrhythmia
- Cardiac arrest
- Even patients with worse prognosis regain a good prognosis with treatment using radio-frequency ablation.
- The overall risk of death in patients with WPW syndrome reaches 0.15% every year.
- Patients with WPW pattern can remain asymptomatic through all their lives, nearly 65% of adolescents and 40% of adults present ECG changes but remain asymptomatic.[2]
- Long-term mortality in adult patients with WPW syndrome is low and similar to control patients withoutWPW.[5]
- Long-term rates of atrial fibrillation in adult patients that present with WPW remains high despite ablation.[6]
- Increased risk of atrial fibrillation in ablated WPW patients may be related atrial fibrillation genesis.[7]
