- W4380769061 abstract "Introduction: Left Ventricular Pseudoaneurysm (LVP) is defined as cardiac wall rupture leading to a formation of wall with thrombus, pericardial, or scar tissue functioning as a pouch for blood. A loculated pericardial effusion (LPE), and right ventricular pericardial fistula (RVPF) have never been reported in literature. Here, we report the first case of a 70 year old male who developed a LVP, LPE, and RVPF. Case Description: A 70 year old male with a past medical history of hypertension presented with inferior wall STEMI. Cardiac catheterization demonstrated left anterior descending (LAD) with 80% occlusion and right coronary artery (RCA) with 100% occlusion. Percutaneous intervention of RCA with aspiration thrombectomy and two drug eluting stents was performed. Echocardiogram the following day demonstrated a LVP. A transesophageal echocardiogram (TEE) demonstrated LVP near the mid-inferior interventricular septum draining into the pericardial space, and LPE from the apical inferior left ventricle (LV) extending to the apical cap of the right ventricle (RV). Computed tomography angiography (CTA) demonstrated a multiloculated collection at the inferior septal aspect of LV contained by the pericardial space. Patient was a high risk for surgery. LVP was closed via a 24 mm atrial septal defect (ASD) occluder device. Intraoperative TEE demonstrated an ASD occluder device at the mid inferior septum at the location of the LVP neck with minimal residual flow into the LPE and a fistula connecting the LPE space with RV. RVFP was managed conservatively. LAD was managed medically. Patient was discharged home safely on guideline directed medical therapy. Discussion: LVP rate is 0.0026% following myocardial injury. It is reported that untreated LVP have a rupture risk of about 30% and a mortality rate of 50%. Prompt treatment is required to prevent mortality. Surgical management is the standard of care. A multidisciplinary heart team deemed the patient a high risk. Therefore, transcatheter treatment was sought in the patient above. Conclusions: Surgical treatment is standard of care for LVP, but transcatheter wall closure with an ASD device is a promising technique not only for high-risk surgical candidates such as above, but as a gold standard of treatment for LVP." @default.
