Se intentó el cierre percutáneo de la comunicación interventricular postinfarto (CIVPI) en 19 pacientes: 2 con recanalización tras el cierre quirúrgico y 17 con CIVPI primaria. En estos últimos, el procedimiento se realizó en 3 pacientes con CIVPI aguda dentro de las primeras 3 semanas postinfarto, en 13 con CIVPI subaguda 3,5-12 semanas postinfarto y en uno con CIVPI crónica. Se llevaron a cabo 22 intervenciones mediante la utilización de 17 oclusores Amplatzer auriculares, 2 ventriculares postinfarto y 2 ventriculares musculares. El procedimiento fue satisfactorio en 14 pacientes: 11 con CIVPI subaguda, uno con CIVPI crónica y 2 posquirúrgicos. El cierre percutáneo de CIVPI con el Amplatzer Atrial Occlusor es probablemente el tratamiento de elección en pacientes con más de 3,5 semanas después del infarto de miocardio y en casos con recanalización tras el cierre quirúrgico.

We carried out transcatheter procedures to close postinfarction ventricular septal defects (PIVSDs) in 19 patients: two had recanalization after surgical closure, and 17 had a primary PIVSD. In three of the latter patients, who had acute PIVSDs, the procedure was carried out in the first 3 weeks after infarction; in the 13 patients with subacute PIVSD, it was carried out 3.5-12 weeks after infarction. There was another procedure in one patient with chronic PIVSD. In total, 22 procedures were completed: 17 using an Amplatzer atrial septal occluder, two using an Amplatzer postinfarction ventricular septal defect occluder, and two using an Amplatzer muscular ventricular septal defect occluder. The procedure was successful in 14 patients: in 11 with subacute PIVSD, one with chronic PIVSD, and two with postsurgical PIVSD. Transcatheter closure of PIVSDs using an Amplatzer atrial septal occluder is probably the treatment of choice in patients undergoing surgery more than 3.5 weeks after myocardial infarction and in those with recanalization after previous surgical closure.

    Patients were managed for 3.5 to 12 weeks post-intervention. The authors of this study concluded that patients who were managed in the chronic phase (>3 weeks) had a better mortality rate as compared to earlier intervention [31]. Assenza et al. also conducted a prospective cohort study of 12 patients using a variety of devices including Clamshell, CardioSEAL, and Starflex (NMT Medical, Inc., Boston, Massachusetts).

    Five patients ended up requiring surgical intervention after device placement. Another cohort of 17 patients with primary post-MI VSD studied by Bialkowski et al. [14] aged between 53 and 81 years had a survival rate of 65%. Patients managed in the post-acute phase, defined as >3 weeks in their study, had a better mortality rate as compared to earlier intervention.

  • Ventricular septal rupture: A rare post-myocardial infarction complication with a very high mortality rate

    2015, European Geriatric Medicine
    Citation Excerpt :

    Transcatheter approach using the post-MI Amplatzer Ventricular Septal Defect device represents an attractive and less invasive option for selected cases [5,6]. The transcatheter approach provides either initial hemodynamic stabilization by reducing the left-to-right shunt (bridge to surgery) [7,8] or definitive treatment, but experience with this approach is still limited, and residual shunts are common [5–14]. Furthermore early intervention, in particular for those presenting with cardiogenic shock is also associated with a high mortality rate.
