„Application of intracardiac echocardiography in a patient with
challenging heart anatomy and focal atrial tachycardia
Abstract
A 62-year-old female with multiple sclerosis in remission was admitted
for electrophysiological study due to persistent tachycardia episodes.
Patient had been experiencing heart palpitations for 30 years, symptoms
intensified post-respiratory infection in 2018, leading to daily
arrhythmia by 2023. Holter monitoring revealed supraventricular
tachycardia (115-120 bpm), with subsequent hospital telemetry confirming
frequent arrhythmia. The diagnostic process, guided by intracardiac
echocardiography, uncovered an aneurysmal interatrial septum. Ablation
procedures targeting an aneurysmal interatrial septum successfully
terminated arrhythmia, confirmed by follow-up over six months. The case
underscores the importance of intracardiac echocardiography in
navigating challenging cardiac anatomy during electrophysiological
interventions.
