Novel use of Konar-multifunctional occluder

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Pediatric Cardiology

Background:

• The Konar-multifunctional occluder is a novel device primarily indicated for ventricular septal defect closure.
• Its design suggests potential utility in a broader range of structural cardiac defects.

Purpose of the Study:

• To evaluate the non-conventional use of the Konar-multifunctional occluder in congenital heart defects (CHD) other than ventricular septal defects.
• To assess the safety, efficacy, and outcomes of using this device in varied cardiac lesions.

Main Methods:

• Retrospective review of eight patients undergoing interventions with multifunctional occluders for non-ventricular septal defect lesions.
• Analysis of patient demographics, lesion type and size, procedural success, complications, and 6-month follow-up.
• Occluder sizing and procedural approach tailored to specific pathologies.

Main Results:

• The cohort median age was 3.2 years and weight 9 kg.
• Indications included patent ductus arteriosus (6 patients), aorto-pulmonary window (1), and coronary arterio-venous fistula (1).
• No major complications, device embolization, or malposition occurred; one patient required occluder replacement due to residual flow.

Conclusions:

• The Konar-multifunctional occluder demonstrates safety and efficacy when used for lesions beyond ventricular septal defects under specific circumstances.
• Its versatile characteristics make it a valuable option for treating diverse congenital heart disease lesions.
