Patients with mechanical “hardware” in the heart, such as
those with mechanical cardiac valves or atrial septal closure devices,
represent a population at high risk of developing AF. Catheter ablation of AF
in these subjects might represent a challenge, due to the perceived higher risk
of complications due to the presence of intracardiac mechanical devices.
Accordingly, such patients have been excluded or poorly represented in major
trials proving the benefit of catheter ablation for the rhythm-control of AF. However,
recent evidences support the concept that catheter ablation procedures might be
equally effective in these patients, without a significant increase in the risk
of procedural complications. This review will summarize the current
state-of-the-art on catheter ablation of AF in patients with mechanical
“hardware” in the heart.
