[Asymptomatic ventricular pre-excitation: what management?]

Area of Science:

• Cardiology
• Electrophysiology

Background:

• The management of asymptomatic ventricular pre-excitation remains controversial.
• Lack of current arrhythmias does not guarantee a benign prognosis due to variable accessory pathway conduction.

Purpose of the Study:

• To define the individual arrhythmia risk in patients with asymptomatic ventricular pre-excitation.
• To guide management strategies balancing intervention and observation.

Main Methods:

• Utilizing a combination of non-invasive and invasive diagnostic tools for risk stratification.
• Evaluating accessory pathway conduction properties.

Main Results:

• Asymptomatic status does not exclude the risk of potentially malignant arrhythmias.
• A consensus suggests a combined diagnostic approach for accurate risk assessment.

Conclusions:

• Neither aggressive ablation nor a strict 'wait-and-see' approach is universally justified.
• Invasive assessment is warranted when non-invasive methods fail to rule out poor accessory pathway conduction, guiding necessary therapy.
