Percutaneous Transcatheter Approach to Partial Anomalous Pulmonary Venous Return: A Case Series

Area of Science:

• Cardiology
• Interventional Cardiology
• Congenital Heart Disease

Background:

• Partial anomalous pulmonary venous return (PAPVR) is a rare congenital heart defect.
• Traditionally managed with surgical correction, often in youth.
• Adult patients, especially non-surgical candidates, have limited treatment options.

Purpose of the Study:

• To demonstrate the technique and safety of percutaneous occlusion for adult PAPVR.
• To evaluate the feasibility of transcatheter closure in patients unsuitable for surgery.
• To assess the impact of percutaneous closure on hemodynamic status and cardiac remodeling.

Main Methods:

• Case series describing percutaneous closure of anomalous pulmonary venous return in adult PAPVR patients.
• Utilized various transcatheter techniques, sometimes in combination, to achieve occlusion.
• Focused on patients with indications for intervention but without surgical options.

Main Results:

• Successful percutaneous closure achieved in 3 adult patients.
• Demonstrated improvement in patient symptoms and hemodynamic status post-procedure.
• Observed positive remodeling in right heart chamber sizes in 2 patients.

Conclusions:

• Percutaneous occlusion of PAPVR is a feasible and safe interventional cardiology approach.
• Offers a novel, minimally invasive treatment alternative for adult patients with PAPVR, particularly non-surgical candidates.
• Transcatheter closure effectively addresses hemodynamic consequences and can lead to cardiac structural improvements.
