Successful endovascular treatment of aortic arch aneurysm in a pediatric patient.

Background: Ascending aortic aneurysms are rare pathologies in childhood, especially in the absence of previous diseases such as Marfan syndrome.

Objective: Present the possibility of successful endovascular management of large vessel aneurysms, using stents and microcatheters with embolization of the aneurysm sac.

Method: We present the case of a previously healthy ten-year-old patient, in whom a pseudoaneurysm was documented between the origin of the left common carotid artery and left subclavian artery, successfully managed endovascularly, initially with a stent covering the neck of the aneurysm to remodel it and later with embolization of the aneurysm sac using a microcatheter.

[Tratamiento endovascular exitoso de aneurisma del ventrículo izquierdo en un paciente pediátrico].

Background: Aneurysms and diverticula of the left ventricle are rare entities in childhood, with a prevalence of less than 0.1%. Described since 1886, as a severe and potentially fatal disease if not corrected, mainly due to the presence of associated anomalies and the risk of rupture.

Interatrial Septum Stenting for Hypoplastic Left Heart Syndrome in Ex Utero Intrapartum Therapy.

Patients with hypoplastic left heart syndrome (HLHS) with intact atrial septum have an increased mortality rate. This presentation occurs in 6% to 10% of cases. We present a patient with fetal diagnosis of HLHS with restrictive atrial septum.

Presence of a Septal Occluder Is No Longer an Obstacle for Pulmonary Vein Isolation by Cryoablation.

Cryoablation for pulmonary vein isolation in atrial fibrillation has been considered a relative contraindication in the presence of a septal occluder device. We describe the successful conduct of this technique with a multimodality imaging approach.

[The mitral annulus disjunction as a risk marker in mitral valve prolapse].

Disjunction of the mitral valve annulus is a structural abnormality consisting of an atrial displacement of the articulation point of the mitral valve, leading to an altered spatial relationship between the valve and the adjacent posterior ventricular wall. Studies have shown the relationship between mitral annular disjunction, ventricular arrhythmias, and myocardial fibrous degeneration, which increases the risk of sudden death, especially among young women. The case of a 30-year-old woman with no relevant pathological history with frequent palpitations is presented, in whom an increase in ventricular automatism with a progressive increase in the arrhythmic load of up to 20% with a weight of pharmacological management is documented.
