Arteriovenous malformations (AVMs) are rare congenital vascular malformations with associated morbidities. We describe a neonatal case of upper limb high-flow AVM presenting with upper limb soft tissue mass and postnatal high-output heart failure. Doppler study suggested high-flow AVM, and later magnetic resonance angiography of the right upper limb confirmed the diagnosis.

Background: The Magenta Elevate is a 9-F, self-expanding, catheter-mounted pump delivered sheathed through a commercially available 10-F femoral introducer over the wire to the left ventricle (LV), providing temporary hemodynamic support up to an equivalent of normal cardiac output.
Objectives: The authors sought to assess the feasibility and outcomes of Elevate-supported high-risk percutaneous coronary intervention (HR-PCI) in a first-in-human study and study the hemodynamic impact of high-output support during prolonged interventional left main coronary artery (LM) occlusions.
Methods: In this study, 14 patients underwent Elevate-supported HR-PCI, with 8 patients undergoing 20 prolonged (39 ± 16 seconds) balloon occlusions of an unprotected LM.

When encountering severe hypoxemia that does not respond to oxygen supplementation, it is essential to consider underlying right-to-left shunting. Among various diagnostic approaches, the microbubble test via transthoracic echocardiography (TTE) is a simple, noninvasive method for detecting pulmonary arteriovenous shunts, particularly in hepatopulmonary syndrome (HPS). Although microbubbles are usually administered peripherally, using a Swan-Ganz (SG) catheter to inject microbubbles directly into the pulmonary artery may provide even more definitive diagnostic information.

Subclavian arteriovenous fistulas (AVFs) are rare entities, mostly reported as a result of traumatic and iatrogenic injuries. In the literature, congenital subclavian AVFs are also presented. Diagnosis of traumatic AVF may present challenges given the variable clinical presentation, varying location, and difficulty to locate on imaging.

Vein of Galen malformations (VOGMs) are rare and complex congenital vascular anomalies that can lead to severe morbidity and mortality. Management predominantly focuses on postnatal endovascular interventions. However, these may not be feasible for fetuses with hemodynamic instability and high-output cardiac failure and may fail to prevent irreversible brain damage induced by prolonged compression by the venous varix, hemodynamic alterations and resultant potential ischemic injury.
