Insights

Mapping complex atrial tachycardias (AT) is difficult. The Advisor HD Grid catheter effectively identified critical signals in a challenging scar-related AT case, enabling successful ablation.

Area of Science:

  • Electrophysiology
  • Cardiac Mapping
  • Catheter Ablation

Background:

  • Scar-related atrial tachycardias (AT) pose significant mapping challenges.
  • High-density (HD) mapping catheters are crucial for complex arrhythmia identification.

Observation:

  • The Advisor HD Grid is a unique directional HD mapping catheter.
  • It captures wavefront propagation direction, particularly in low-voltage zones.

Findings:

  • In a complex scar-related AT case, the Advisor HD Grid revealed distinct fractionated signals at the isthmus.
  • These signals were absent on the ablation catheter despite adequate contact force.

Implications:

  • This directional HD mapping technology can improve AT mapping accuracy.
  • It facilitates precise ablation targeting in challenging cardiac cases.

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
