There is one clinical trial.
This prospective study aims to examine the association of specific genetic variants (single nucleotide polymorphisms) located on chromosome 1, 4 and 16, with presence of non-pulmonary vein triggers (NPVT) as well as ablation-outcome in AF patients
Previous left atrial catheter ablation or MAZE procedure 2. Reversible causes of atrial arrhythmia such as hyperthyroidism, sarcoidosis, pulmonary embolism etc Atrial Fibrillation Atrial Fibrillation Specific Aim: This prospective pilot study aims to examine the association of specific genetic variants (single nucleotide polymorphisms) namely rs2200733, rs6843082, rs10033464, rs17042171, rs2106261 and rs13376333 on chromosome 1, 4 and 16, with presence of non-pulmonary vein triggers (NPVT) as well as ablation-outcome in AF patients.
Description: Isolation of pulmonary-vein antra and all extra-pulmonary vein triggers
Measure: PVAI and isolation of all non-PV triggers Time: 1 hour of the ablation procedureDescription: Recurrence will be defined as freedom from atrial flutter (AFL), AF or atrial tachycardia (AT) of > 30 seconds duration, in the absence of anti-arrhythmic drugs (AADs) at follow-up.
Measure: Recurrence of arrhythmia Time: Within 1 year of follow-up
