Answers are grounded in this paper and cite their sources.
Left atrial ablation may lower pacemaker risk versus biatrial in valvular disease; leaves open randomized confirmation.

Bogachev-Prokofiev et al. (2018) conducted an observational in Valvular heart disease and persistent or long-standing persistent atrial fibrillation (n=312). Biatrial ablation vs. Left atrial ablation was evaluated on Pacemaker implantation (OR 5.75, 95% CI 2.16-15.29, p=<0.001). Biatrial ablation was associated with a significantly higher rate of pacemaker implantation compared to left atrial ablation (17.3% vs. 3.8%, OR 5.75) primarily due to sinus node dysfunction.
