Key result
The Advisor HD Grid catheter provided high-quality signals that allowed for precise entrainment mapping and successful ablation of a complex perimitral atrial tachycardia.
Why the study?
Determining tachycardia circuits in complex ATs after catheter ablation or a MAZE procedure is sometimes difficult.
Population
A patient with a perimetral AT with epi-endocardium breakthrough after a MAZE surgery and catheter ablation

Population
A 50-year-old male with a perimitral atrial tachycardia with an epi-endocardium breakthrough after a MAZE surgery and catheter ablation.
I
Intervention
High-density grid mapping catheter (Advisory HD Grid catheter) for 3D electro-anatomical and entrainment mapping, followed by radiofrequency catheter ablation.
O
Outcome
Successful mapping and termination of the atrial tachycardia.
The high-density grid mapping catheter provides precise signals that facilitate detailed entrainment mapping and successful ablation of complex post-MAZE atrial tachycardias.
Cite This Study
Oikawa et al. (2020) conducted a case report in Perimitral atrial tachycardia (n=1). High-Density Grid Mapping Catheter (Advisor HD Grid) was evaluated on Diagnosis and termination of tachycardia. The Advisor HD Grid catheter provided high-quality signals that allowed for precise entrainment mapping and successful ablation of a complex perimitral atrial tachycardia.
