Mapping catheter-related mitral valve injury: a case report.

ABSTRACT:

Background

An increasing number of catheter ablations are performed for symptomatic tachyarrhythmias and commonly involve the left atrium, increasing the risk of catheter interaction with the mitral valve (MV) complex. Mitral valve trauma at the time of atrial fibrillation (AF) ablations remains a rare yet emergent situation that requires prompt diagnosis and management to prevent the long-term sequelae of heart failure secondary to MV dysfunction.

Case summary

We present a case of a 69-year-old female with symptomatic paroxysmal AF and atrial flutter who underwent a combined ablation procedure. During the pulmonary vein isolation procedure, the mapping catheter became entangled within the MV apparatus but was freed. She presented to our hospital 2 weeks later with dyspnoea,
