In adult cardiac arrest (CA) patients treated with targeted temperature management (TTM), male sex, bystander cardiopulmonary resuscitation (CPR) and the presence of initial shockable rhythm all correlate with greater chances of favourable neurological outcomes, a recent meta-analysis has shown.

Reablation common after cavo tricuspid isthmus ablation

14 Jan 2020

Reablation for atrial flutter and ablation for atrial fibrillation (AF) remain relatively common after cavo tricuspid isthmus ablation (CTIA), a recent study has found.

The study included 2,409 patients (median age, 66 years; 81 percent male) undergoing their first CTIA procedure between 2010 and 2016. Incidences of repeat CTIA or ablation for AF were documented until 1 March 2018. Majority of the population (n=2,288; 95 percent) achieved acute procedural success; 13 participants (0.5 percent) experienced complications.

Over a mean follow-up duration of 4.0±1.7 years, 242 patients required repeat CTIA, yielding a rate of 10 percent. Slightly more patients required ablation for AF (13.5 percent; n=326). Thirty-eight (2 percent) underwent both procedures.

Cox regression analysis found that patients who had longer operation times for the first CTIA procedure (hazard ratio [HR], 1.003, 95 percent confidence interval [CI], 1.001–1.006; p=0.01) and having an unsuccessful initial operation (HR, 3.42, 95 percent CI, 2.10–5.55; p<0.0001) were significantly more likely to need repeat procedures. Older age was likewise significantly associated (75 vs <65 years: HR, 0.66, 95 percent CI, 0.44–0.97; p=0.04).

In comparison, the use of a contact force sensing catheter emerged as a significant risk factor for having to undergo ablation for AF (HR, 1.43, 95 percent CI, 1.13–1.81; p=0.003). Other pertinent factors were the presence of valvular heart disease (HR, 0.39, 95 percent CI, 0.21–0.72; p=0.002) and known AF prior to CTIA (HR, 1.71, 95 percent CI, 1.07–2.73; p=0.02).
