Percutaneous myocardial ablation in double-chamber right ventricle

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Double-chamber right ventricle (DCRV) is a congenital heart defect characterized by intracavitary outflow obstruction.
• Surgical intervention is the traditional treatment for DCRV, but carries significant risks, especially in elderly patients.

Observation:

• A 73-year-old patient with symptomatic DCRV presented with significant intracavitary outflow obstruction.
• The patient was deemed a high-risk candidate for conventional surgical treatment.

Findings:

• The study reports the first successful percutaneous myocardial ablation of DCRV using alcohol-induced conus branch occlusion.
• This minimally invasive procedure resulted in a significant reduction of the pressure gradient from 81 to 48 mm Hg.
• The patient experienced notable clinical improvement following the intervention.

Implications:

• Percutaneous myocardial ablation represents a promising alternative therapeutic strategy for adult patients with DCRV.
• This approach may offer a less invasive option compared to traditional surgery, particularly for high-risk individuals.
• Further research is warranted to establish the long-term efficacy and safety of this technique.
