- St. Vincent Cardiovascular Research Institute
- Brief Summary
There has not been a prospective, randomized controlled trial of colchicine to reduce post-AF ablation pericarditis in an era of newer AF ablation techniques. The hypothesis is that an empiric pre and post AF ablation treatment protocol with colchicine may reduce the incidence and symptom severity of post-AF ablation related pericarditis. Thus, the goal of this study is to
1. Identify the incidence of post-AF ablation related pericarditis in patients undergoing ablation via high power, short duration strategy (shorter total RF time, but increased stability due to steerable catheters and possible difference from resistive vs conductive heating).
2. Identify potential differences in patients undergoing PVI only versus PVI + additional ablation
3. Identify whether patients on who are already on anti-inflammatories such as ASA or statins have a lower incidence than those without
4. Determine if an empiric treatment strategy with colchicine (for 7 days post ablation) reduces the incidence of post-operative AF
- Detailed Description
This study will be a prospective, randomized controlled study of 248 patients presenting to the electrophysiology lab at Ascension St. Vincent (Indianapolis, IN) and Ascension Sacred Heart (Pensacola, FL) for atrial fibrillation ablation. Cases will be randomized in sequential order.
The control arm will undergo standard of care, whereas the study arm will undergo treatment with colchicine 0.6mg PO BID for 7 days following ablation.
Study variables will consist of
* Patient demographics
o age, gender, comorbidities (HTN, HLD, DM-2, COPD, tobacco use, OSA, CKD, weight in kg, BMI, LVEF, autoimmune inflammatory condition such as RA), type of AF (paroxysmal, persistent, etc.)
* Medical therapy characteristics
o anticoagulation choice, statin present, aspirin present, discontinuation of colchicine due to gastrointestinal distress
* Procedural characteristics o length of procedure, initial vs redo procedure, PVI only versus PVI + additional lines, total RF application time, HPSD vs MPMD approach, #RF applications, Power, Contact force, Impedance
Rates of acute post-operative pericarditis will be compared between the two groups. Subjects will be called by study personnel within 7-14 days to identify any post-ablation symptoms. If a patient develops pericarditis, standard anti-inflammatory therapy will be initiated in those patients regardless of study arm.
The primary outcome will be the development of post-AF ablation pericarditis within 30 days of ablation. This will be ascertained by comprehensive chart review and at the routine post-ablation follow up visit; additionally, there will be a standard telephone survey administered 7-14d after ablation (see instrument). Secondary outcomes will include symptoms, incidence of post-ablation AF recurrence, patient satisfaction using a Likert scale, and other clinical variables.

Group Intervention Description Colchicine Colchicine 0.6mg colchicine oral twice daily for 7 days.
- Primary Outcome Measures
Name Time Method Proportion of patients with Pericarditis Postoperative day 30. Clinical pericarditis ascertained by comprehensive chart review and a follow up phone call using a survey instrument.
- Secondary Outcome Measures
Name Time Method Median rating of patient satisfaction on a Likert scale, comparing the study group and standard of care group. Postoperative day 14 Patient satisfaction with ablation and post ablation care, measured on a Likert scale (min 1 and max 5, with 1 being best and 5 being worst) and derived from a telephone survey.
Proportion of patients with recurrent Atrial fibrillation Through study completion, an average of 1 year Recurrence of atrial fibrillation post ablation
