• It is important to recognize that catheter It is important to recognize that catheter ablation of AF is a demanding technical ablation of AF is a demanding technical procedure that may result in complicationsprocedure that may result in complications

• Patients should only undergo AF ablation Patients should only undergo AF ablation after carefully weighing the risks and after carefully weighing the risks and benefits of the procedurebenefits of the procedure

Indications for AF Catheter Ablation

• Symptomatic AF refractory ≥ 1 AAD Symptomatic AF refractory ≥ 1 AAD (Class I, III)(Class I, III)

• AF ablation as first line therapy (rare AF ablation as first line therapy (rare clinical situations)clinical situations)

• Careful identification of PV ostia is mandatoryCareful identification of PV ostia is mandatory

• If additional lesions are applied, line completeness If additional lesions are applied, line completeness should be demonstrated should be demonstrated

• RAI block only in pts with typical or inducible AFLRAI block only in pts with typical or inducible AFL

• Non PV triggers should be targeted if possibleNon PV triggers should be targeted if possible

• If pts with longstanding persistent AF are If pts with longstanding persistent AF are approached, ostial PVI may not be sufficentapproached, ostial PVI may not be sufficent

Technique / Lab Managements
