Ventricular Septal Defect Closure Devices, Techniques, and Outcomes.

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Device Technology

Background:

• Transcatheter closure of ventricular septal defects (VSDs) was first described in 1988.
• Early VSD closure attempts faced high complication rates, notably complete heart block.
• Advancements in vascular occlusion devices have expanded treatment options and improved safety profiles.

Purpose of the Study:

• To evaluate the evolution and current safety of transcatheter VSD closure.
• To compare complication rates, particularly complete heart block, between historical and contemporary VSD closure methods.
• To assess the impact of novel occlusion devices on patient selection and outcomes.

Main Methods:

• Review of historical and contemporary studies on transcatheter VSD closure.
• Analysis of complication rates, focusing on incidence of complete heart block.
• Comparison of outcomes between transcatheter and surgical VSD closure approaches.

Main Results:

• Contemporary transcatheter VSD closure utilizes novel devices, often off-label.
• Complication rates, especially complete heart block, have significantly decreased.
• Current complete heart block rates in transcatheter VSD closure are comparable to surgical VSD closure.

Conclusions:

• Transcatheter VSD closure has become a safer and more effective treatment option.
• Modern occlusion devices have substantially improved the safety profile of VSD closure.
• Transcatheter VSD closure now offers complication rates comparable to surgical intervention.
