[3D-transthoracic echocardiography: a selection method prior to percutaneous closure of XXXX ].

@entity1 @entity118 @entity1757
Prior to putting in place a percutaneous device, the assessment of the @entity118 anatomy is mandatory. The 3D transthoracic echocardiography is a non-invasive method bringing an imaging of the @entity1757 surface and its borders. Fifty-two @entity1 ageing from 3 to 16 years old had a rotational 3D transthoracic echocardiography. Thirty-six (69%) were selected for a percutaneous closure (borders > 7 mm and a septal surface/ @entity118 ratio > 2). Thirty-two of these selected @entity1 (89%) benefited from the Amplatz prosthesis implantation with success. The maximal 3D diameter of the @entity1757 was 20 + 4 mm (14-30) compared to the mean size of prosthesis at 22 mm (18-30). Four of the 36 @entity1 (aneurismal septum or a borderline septal surface/ @entity118 ratio) were secondarily oriented to surgeons. Sixteen @entity1 (31%) were selected directly to a surgical closure. The lack of borders or septal surface were confirmed by the surgical view. The 3D transthoracic echocardiography allows to define new criteria for the selection of @entity1 prior to a percutaneous closure of @entity118 . This prospective study demonstrates that 9 out of 10 @entity1 who had the 3D criteria had a percutaneous closure of the @entity1757 .
