Hybrid closure of postinfarction ventricular septal rupture enlargement after transcathether closure with Amplatzer occluder.
Ventricular septal rupture (VSR) is nowadays a rare complication of myocardial infarction (MI), but with a mortality rate still very high. Urgent surgical correction is recommended, although in specific cases percutaneous closure of a post-infarct VSR is a therapeutic option or a bridge to surgical correction. We report a case of an 80-year-old woman, with a subacute anterior MI with an antero-septal VSR. Rapid clinical deterioration in a high-surgical-risk patient led us to attempt percutaneous VSR closure at day 8 post MI. A 16-mm Amplatzer post-infarction (PI) muscular VSD closed the defect with intra-cardiac echocardiography guidance, that allowed conscious sedation. Clinical and haemodynamic improvement was immediate. Unfortunately, a small orifice distal to the device persisted, which enlarged to 8 mm over the following days, with a Qp/Qs shunt of 1.9. At day 17 post MI, the VSR was surgically closed by suturing the Amplatzer device to the septum. A residual shunt was evident, but with no progression, being the patient discharged in NYHA class I. Percutaneous closure of a post-MI VSR as a bridge to surgery is a therapeutic option in patients with high surgical risk, allowing haemodynamic stabilization and thus gaining time for a further surgical intervention if needed, improving these patients grim prognosis. Intra-cardiac echocardiography for monitoring the percutaneous procedure instead of a transoesophageal approach, as well as the surgical technique, make this case unique.
