Author ProfileAbstract
Catheter ablation involving the left ventricle increases risk of damage
to the mitral valve or chordae tendineae which can lead to acute mitral
regurgitation. This may place the patient in danger whether using a
transaortic approach or transseptal approach. Here we report a case
diagnosed as ablation catheter entrapment by chordae of the mitral valve
during radiofrequency ablation monitored by periprocedural
transesophageal echocardiogram. The entrapped ablation catheter was
smoothly removed by open surgery and no damage to the mitral valve
complex was detected. Removal of an entrapped catheter by blinded
traction is associated with damage to the mitral valve complex.Dec 2021Published in The Kaohsiung Journal of Medical Sciences volume 37 issue 12 on pages 1124-1125. 10.1002/kjm2.12438
