Tratamento percutâneo de pseudoaneurismas do ventrículo esquerdo e da aorta: série de três casos

Left ventricular pseudoaneurysms are usually associated with acute myocardial infarction; however, these conditions may emerge in the late postoperative period of valvar surgery, and this can also occur with aortic pseudoaneurysms. These pseudoaneurysms often affect patients with high surgical risk, and percutaneous treatment is usually performed in reference centers for treatment of congenital heart diseases, due to anatomical characteristics of these defects. We present two cases of left ventricular pseudoaneurysms treated by transapical approach without need for cardiopulmonary bypass, and one case of aortic pseudoaneurysm treated by femoral approach, in which a snare was introduced by contralateral access, to allow for adequate support and guidance of the long sheath for accessing the defect.
