Late peri-procedural DHF
Our study showed that 9 (90%) patients developed early recurrence of AF
before late peri-procedural DHF. AF results in a rapid ventricular heart
rate.17 In addition, loss of effective atrial
contractile function occurs.17 These factors lead to a
reduction in cardiac output, so AF is a risk factor for
DHF.17 Our study also showed early recurrence of AF
was an independent predictor of DHF, especially of late peri-procedural
DHF. A previous study showed that 78% of early recurrence of AF
occurred within 7 days after catheter ablation.18 It
is thought that early recurrence of AF often occurs at some point and
contributes to late peri-procedural DHF.
