A 78-year-old woman was brought to our hospital for chest pain with shock status. An electrocardiogram showed ST elevation in the precordial leads. Echocardiography showed an anteroseptal wall motion abnormality with left-to-right shunt at the apex. Emergency coronary angiography revealed occlusion in the mid portion of the left anterior descending artery, and left ventriculography showed ventricular septal rupture (VSR). Despite successful emergency surgical VSR repair, the VSR recurred 10 days after surgery, and the patient required intra-aortic balloon pumping and mechanical ventilation. Although reoperation for VSR closure was attempted 33 days after admission, open heart surgery was not completed due to severe tissue adhesions from the prior cardiac surgery. The patient ultimately underwent transcatheter closure for VSR using an Amplatzer duct occluder 56 days after hospital admission, and her hemodynamics markedly improved. She was transferred to a regional hospital for rehabilitation without oxygen therapy or intravenous treatments 81 days after the percutaneous intervention. In conclusion, percutaneous device closure of post-infarction VSR may be an alternative treatment to surgical repair for inoperable cases.

Introduction Ventricular septal rupture (VSR) is a rare but critical complication that usually occurs within 1 week after acute myocardial infarction (AMI) [1]. Patients without surgical repair of VSR show a high mortality rate of 76% within 1 month, and emergency surgical repair is necessary. However, the in-hospital mortality rate is still high at 47%, and depends on the patient’s preoperative condition [2,3]. Here, we describe the successful transcatheter closure of a

recurrent post-infarction VSR using an Amplatzer duct occluder (ADO) in a patient who had undergone emergency surgical repair. Case report A 78-year-old woman was referred to our hospital with cardiogenic shock 2 days after the first episode of chest pain. Upon hospital admission, her blood pressure was 78/52 mmHg and her pulse rate was 104 beats/min. Physical examination revealed internal jugular venous dilatation and a grade 3 pan-systolic murmur at the apex. Her 12-lead electrocardiogram showed ST elevation in leads V2–V5. Echocardiography in the emergency room revealed akinesis in the mid anterior septum and apex, and VSR in the apical interventricular septum with left-to-right shunt

flow (Fig. 1A). On intra-aortic balloon pump (IABP) insertion, coronary angiography revealed total occlusion of the mid left anterior descending and mid left circumflex arteries. Left ventriculography showed a substantial left-to-right shunt through the VSR (Fig. 1B). She underwent urgent two-vessel coronary artery bypass grafting and surgical patch closure for VSR using the David– Komeda procedure. Although the postoperative course was favorable, the pan-systolic murmur reappeared at the apex and heart failure was exacerbated 11 days after operation. A transesophageal echocardiogram (TEE) showed the presence of VSR (Fig. 2A). Contrast-enhanced computed tomography showed dehiscence of the surgical patch and recurrence of VSR (Fig. 2B). A second attempt at surgical repair for VSR closure failed because of severe intra-thoracic adhesions due to the first surgical repair. As the patient required IABP and inotropic support for hemodynamic stabilization, a percutaneous transcatheter closure with an Amplatzer device was performed 56 days after the first operation.
At the time of intervention, TEE showed the defect (diameter: left ventricular side 13 mm, right ventricular side 9 mm, thickness: 8 mm) located at the apex corresponding to the infarct area. The procedure was performed with TEE guidance under general anesthesia in a hybrid operating room. Venoarterial extra corporeal membrane oxygenation (VA-ECMO) was used in preparing for the increase in left-to-right shunt. After the VSR was confirmed by left ventriculography (Fig. 3A), a Judkins right-4 catheter and 0.035-inch wire was used to cross the defect from the left ventricle to the right ventricle, and the wire was advanced into the pulmonary artery. Then, the wire was snared and exteriorized through the left subclavian vein. The stretch diameter of the defect was measured using a calibrated balloon (Fig. 3B), and was found to be 7.8 mm. According to the size of defect and geometric characteristics of the ventricular septal myocardium, ADO 12/10 was selected. A delivery sheath (AMPLATZER TorqVue Delivery System, Abbott, Abbott Park, IL, USA) was advanced from the left

subclavian vein through the defect into the left ventricle using an arteriovenous wire loop. Then, the ADO was deployed after ensuring an adequate position using TEE and angiography (Fig. 3C), and the device was released successfully. TEE and left ventriculography showed that the device sandwiched the septum and covered the defect well (Fig. 3D–F). VA-ECMO support was safely terminated. Repeated right and left heart catheterization revealed reduced mean pulmonary artery pressure from 35 to 25 mm Hg and only a small left-to-right shunt. Qp/Qs improved from 2.5 to 1.2. Her hemodynamics markedly improved thereafter, and IABP and inotropic support were successfully withdrawn. After the procedure, the patient required continuous renal replacement therapy for 5 days due to contrast-induced nephropathy. However, hemolysis due to the small residual shunt was not observed, thrombocytopenia occurred the day after the procedure, and her platelet count dropped from 142 103/ml to 38 103/ml and continued improving over the next 2 weeks. Ventricular arrhythmia did not increase after the procedure. She was ultimately transferred to a regional hospital for cardiac rehabilitation 81 days after the percutaneous intervention for VSR. Discussion We report a case of successful percutaneous closure using an ADO for recurrent post-myocardial infarction VSR after emergency surgical repair. Over 70% of untreated patients with VSR die within the first month [2]. Furthermore, the mortality rate is approximately 50% even after surgery is performed [2–4]. Despite a successful initial repair, VSR recurs in about 20% of patients due to patch dehiscence, development of a new VSR, or an overlooked second VSR [5]. This recurrent complication may cause significant hemodynamic disturbance requiring reintervention, as observed in the present case. Therefore, it is difficult to perform reoperation for recurrent VSR in postoperative patients. In contrast, percutaneous intervention for VSR is less invasive, and is useful when the
patient’s condition is poor. Indeed, previous reports have demonstrated that transcatheter VSR closure is useful for patients with a poor prognosis, with a procedural success rate of 86%. Additionally, transcatheter VSR closure provided long-term efficacy [1–8]. Optimal timing for percutaneous VSR closure has previously been discussed. According to a review article, 46.4% of patients with VSR were treated within the first 2 weeks, and a positive linear relationship exists between the number of acute phase cases and the mortality rate [9]. Thus, closure of post-infarction VSR with an Amplatzer device might be suitable for high-risk VSR patients in the late phase to avoid complications, such as in this case. This is reported to be true even for complications related to percutaneous VSR closure, including device migration, arrhythmia (3rd degree atrioventricular block, ventricular fibrillations/tachycardias), and left ventricular rupture after closure [9]. The choice of devices is important for successful closure of VSR. According to previous reports, most patients with post-infarct VSR were treated with Amplatzer devices [8]. Currently, Amplatzer septal occluder (ASO), Amplatzer cribriform occluder, and ADO devices are available, however, the Amplatzer VSD occluder is not yet available in Japan. Tada et al. reported a case of successful percutaneous closure of post-infarction VSR using an ASO in Japan [10]. In the present case, due to the structural characteristics of VSR, ADO was considered to be more effective than ASO for the following reasons. First, because the VSR was located at the apex, it was surrounded by a small rim and the shorter size of the ADO disk compared with the ASO disk was expected to fit better in this space. Second, because it had been 2 months since onset, the myocardium was sufficiently stable, and so the oversized ADO was thought to better fill the defect and seal the shunt. Balloon sizing was performed for the same reasons. We have demonstrated the potential of percutaneous closure as a feasible treatment in recurrent post-infarction VSR following patch repair. However, the usefulness of percutaneous closure for

the treatment of VSR in Japan has not yet been established. To the best of our knowledge, this is the first case of successful percutaneous closure using ADO for recurrence of VSR due to dehiscence of a surgical patch. In conclusion, percutaneous device closure of post-infarction VSR might be an effective alternative treatment to surgical repair when the patient’s condition is poor. Appendix A.
