Summary
This summary is machine-generated.

Radiofrequency (RF) ablation offers a new, minimally invasive catheter-based treatment for recurrent subaortic membrane obstruction. This approach successfully reduced obstruction and improved symptoms in a patient previously treated with surgery.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Cardiac Surgery

Background:

  • Symptomatic subaortic membrane obstruction typically necessitates open surgical intervention, often involving extensive procedures like the Konno procedure.
