Echocardiography-guided Oval-shaped ASD Closure

Echocardiography-Guided Percutaneous Closure of Oval-Shaped Secundum Atrial Septal Defects

Background: An atrial septal defect (ASD) is considered oval-shaped when its shortest diameter is less than 75% of its longest diameter. Research on the percutaneous closure of oval-shaped ASDs is limited, and to our knowledge, there are no reports of non-fluoroscopic closure for this specific population.

Objective: To assess the effectiveness of non-fluoroscopic percutaneous closure for oval-shaped ASDs.

Methods: This single-center, retrospective study examines patients undergoing percutaneous closure of oval-shaped ASDs using a non-fluoroscopy technique for initial decision-making. The device was selected to be approximately 0-4 mm larger than the longest diameter of the defect, based on measurements from transthoracic and transesophageal ultrasound.
