Transcatheter Closure of Intracristal Ventricular Septal Defect With Mild Aortic Cusp Prolapse Using Zero Eccentricity Ventricular Septal Defect Occluder

The Feasibility and Safety of Interventional Occlusion Treatment of Intracristal Ventricular Septal Defects: Clinical Report of 56 Cases

“…After 3 months, the surface of the occluder may be epithelialized; therefore, the friction between the aortic valve and the occluder is minimal, and the occluder is tightly surrounded by the ventricular septum, which eliminates movement. Therefore, the occluder has minimal impact on the aorta [9]. The occluder does not have any impact on the aortic valve, which was confirmed by our long-term follow-up results.…”

Assessment of Ventricular Septal Defect Size and Morphology by Three-Dimensional Transthoracic Echocardiography

“…Several devices of variable configuration are available actually for the percutaneous closure of VSDs. 3,4,23 Three-dimensional echocardiography could be useful in the selection of the appropriate occlusion device configuration according to VSD morphology. 24 However, in this study we did not evaluate this potential application, and further studies are needed to determine the value of this approach.…”

“…1,2 Recently, percutaneous closure of muscular as well as membranous VSDs using different devices has emerged as an alternative to the surgical technique in selected cases. [3][4][5][6] An accurate assessment of the size and morphology of a VSD is of crucial importance in these cases for device choice. Morphologic assessment of VSD, its diameters, and its dynamic variation throughout the cardiac cycle are difficult to achieve from sequential cuts of one plane by 2D TTE.…”

“…Morphologic assessment of VSD, its diameters, and its dynamic variation throughout the cardiac cycle are difficult to achieve from sequential cuts of one plane by 2D TTE. 4,[7][8][9][10] We and others have reported that three-dimensional (3D) TTE is useful to describe the size, morphology, and dynamic morphology variation of intracardiac defects such as atrial septal defects in children. 11,12 Thus, we hypothesized that 3D TTE would also be useful to assess VSD morphology and size in these population.…”

Percutaneous Closure in Conal Septal Ventricular Septal Defects: Fact or Fiction?

“…Various SHSMA occluders have been described previously for closing select atrial septal defects and patent ductus arteriosus in addition to prior smaller reports for intracristal VSDs [6,8,9]. This device was specifically designed to be asymmetric, with a smaller disc on the left ventricular side of the lesion, thus avoiding impingement on the aortic valve while maintaining adequate septal closure.…”
