Case in brief
A 31-year-old man presented with symptomatic atrial arrhythmia following extra-cardiac Fontan surgery and a MAZE procedure. The unique anatomical features limited percutaneous access, requiring perforation through the extra-cardiac tunnel. Innovative mapping techniques were employed to characterize the electro-morphology of the arrhythmia, leading to successful management of the condition.
What made this case unusual
The case highlighted the challenges of accessing the atria due to the patient's unique anatomy post-surgery, necessitating a novel approach for mapping the arrhythmia.
Diagnostic / clinical pearl
Clinicians should consider the impact of complex surgical anatomy on arrhythmia management, particularly in patients with prior Fontan procedures.
Why it matters
Understanding the electro-morphology of arrhythmias in patients with altered cardiac anatomy can improve diagnostic and therapeutic strategies in similar cases.
