A Study For Treatment Of Paroxysmal Atrial Fibrillation (PAF) With The THERMOCOOL SMARTTOUCH SF Catheter and TRUPULSE Generator

Inclusion Criteria:

• Diagnosed with symptomatic paroxysmal atrial fibrillation (PAF) defined as atrialfibrillation (AF) that terminates spontaneously or with intervention within 7 daysof onset. This PAF is considered to be symptomatic if symptoms related to AF areexperienced by the participant

• Selected for AF ablation procedure by pulmonary vein isolation (PVI)

• Failed at least one antiarrhythmic drug (AAD) (class I to IV) as evidenced byrecurrent symptomatic AF, or intolerable or contraindicated to the AAD

• Willing and capable of providing consent

• Able and willing to comply with all pre-, post- and follow-up testing andrequirements.

Exclusion Criteria:

• Previously known AF secondary to electrolyte imbalance, thyroid disease, orreversible or non-cardiac cause (example, documented obstructive sleep apnea, acutealcohol toxicity, morbid obesity {Body Mass Index greater than [>] 40 kilograms permeter square [kg/m²]}, renal insufficiency (with an estimated creatinine clearanceless than [<] 30 milliliters [mL]/ minute [min]/1.73 meter square [m2] )

• Previous left atrium (LA) ablation or surgery

• Patients known to require ablation outside the pulmonary vein (PV) region (example,atrioventricular reentrant tachycardia, atrioventricular nodal reentry tachycardia,atrial tachycardia, ventricular tachycardia and wolff-parkinson-white)

• Previously diagnosed with persistent AF [greater than (>) 7 days in duration]

• Severe dilatation of the left atrium (LA) (Left anterior descending artery [LAD] >50mm antero-posterior diameter in case of Transthoracic Echocardiography [TTE])
