Gastroesophageal Reflux Disease II: Clinical Features and Management

78
Gastroesophageal reflux disease, or GERD, is a persistent medical condition that affects many individuals worldwide. Its clinical manifestations can vary greatly, making diagnosis and management challenging for healthcare professionals. The following is a comprehensive overview of the clinical manifestations, assessment, and management strategies for GERD.
Clinical Manifestations
GERD presents itself in a multitude of ways, with symptoms varying from person to person. The hallmark symptoms are...

Area of Science:

  • Cardiac Electrophysiology
  • Medical Device Technology

Background:

  • Proactive esophageal cooling is FDA-cleared to mitigate esophageal injury during radiofrequency (RF) cardiac ablation.
  • Esophageal cooling may reduce procedure times for RF pulmonary vein isolation (PVI) compared to luminal esophageal temperature (LET) monitoring.

Purpose of the Study:

  • To quantify the impact of proactive esophageal cooling on electrophysiology (EP) lab throughput for PVI cases.
  • To evaluate changes in EP lab efficiency following the adoption of esophageal cooling technology.

Main Methods:

  • Retrospective analysis of EP lab throughput data from three sites before and after adopting proactive esophageal cooling.
  • Comparison of PVI case numbers over equal time frames using LET monitoring versus proactive esophageal cooling.

Main Results:

  • A total of 2498 PVIs were performed; 1026 pre-adoption (LET monitoring) and 1472 post-adoption (esophageal cooling).
  • Proactive esophageal cooling adoption resulted in a mean 43% increase in EP lab throughput (p < .0001).
  • Increased throughput was observed despite a reduction in the number of operators in the post-adoption period.

Conclusions:

  • Adoption of proactive esophageal cooling is linked to a significant rise in EP lab throughput for PVI procedures.
  • This technology enhances procedural efficiency and potentially increases patient access to care.
