Single arterial access closure of post-infarction ventricular septal defect: A case series.

BACKGROUND: Post-infarction ventricular septal defect (PIVSD) carries a very poor prognosis. Surgical repair offers reasonable outcomes in patients who survive the initial healing period. Percutaneous device implantation remains a potentially effective earlier alternative. METHODS AND RESULTS: From March 2018 to May 2022, 11 trans-arterial PIVSD closures were attempted in 9 patients from two centers (aged 67.2 ± 11.1 years; 77.8% male). Two patients had a second procedure. Myocardial infarction was anterior in four patients (44.5%) and inferior in five cases (55.5%). Devices were successfully implanted in all patients. There were no major immediate procedural complications. Immediate shunt grade postprocedure was significant (11.1%), minimal (77.8%), or none (11.1%). Median length of stay after the procedure was 14.8 days. Five patients (55%) survived to discharge and were followed up for a median of 605 days, during which time no additional patients died. CONCLUSION: Single arterial access for percutaneous closure of PIVSD is a good option for these extremely high-risk patients, in the era of effective large-bore arterial access closure. Mortality remains high, but patients who survive to discharge do well in the longer term.

Ultrasound Assessment of Postprocedural Arterial Pseudoaneurysms: Techniques, Clinical Implications, and Emergency Department Integration.

This narrative aims to evaluate the efficacy of point-of-care ultrasound (POCUS) in the early diagnosis and management of postprocedural arterial pseudoaneurysms in the emergency department (ED). We hypothesize that POCUS can be used as the first line of imaging to distinguish vascular from non-vascular causes and diagnose a pseudoaneurysm if present. A comprehensive review of cases involving postprocedural pseudoaneurysms was conducted. We focus on patients who underwent endovascular procedures, including transfemoral and transradial arterial access for cardiac interventions, or received laceration repair after blunt head trauma. We analyzed each case's clinical symptoms, POCUS findings, and subsequent management. POCUS demonstrated high efficacy in early diagnosis by detecting pseudoaneurysm sacs with characteristic bi-directional flows (yin-yang sign) and, in some cases, partial thrombosis. The early identification of potential arterial complications allowed for efficient planning of further imaging and expedited surgical consultation, leading to timely and definitive management. Our study emphasizes the significance of using POCUS as the primary imaging modality for early detection and diagnosis of postprocedural arterial pseudoaneurysms. Incorporating POCUS into the initial assessment of patients presenting with pain and swelling at the site of arterial access or laceration repair can streamline consultation and potentially reduce the need for additional imaging, optimizing patient care in the ED setting.
