Article Abstract
Background: Coronary artery pseudoaneurysms (PSAs) are a rare but potentially life-threatening complication after percutaneous coronary intervention (PCI), typically manifesting between 1 week and 4 years after the procedure. Prompt diagnosis is crucial, particularly in high-risk PSAs, which incur potential for rupture.
Case Summary: The authors report the case of a 77-year-old man in whom a large PSA developed in the left circumflex artery within 30 days of PCI, which was complicated by coronary perforation. During the original procedure, the perforation was sealed by a covered stent; however, anticoagulation was resumed because of atrial fibrillation 2 weeks later. The patient subsequently presented again with chest discomfort, and computed tomographic angiography showed a large PSA at the edge of the stent. Percutaneous closure using a second covered stent achieved complete PSA isolation.
Discussion: This case aims to highlight the importance of precise stent placement, vessel wall apposition, and vigilant follow-up, particularly in patients taking intensive antithrombotic therapy.

Background: Coronary artery aneurysm (CAA) is a rare congenital or acquired coronary malformation, associated with coronary artery fistula (CAF) in approximately 15% of cases. CAA is often asymptomatic.
Case Summary: We report the case of a 60-year-old woman diagnosed in 2017 with a 15-mm large giant left main to left circumflex CAA.

Background: Percutaneous coronary intervention (PCI) with drug-eluting stents (DES) on ostial left circumflex (oLCx) is associated with a high rate of adverse events.
Aims: This study aims to compare drug-coated balloons (DCB) and DES in the treatment of oLCx lesions.
Methods: Consecutive patients undergoing DCB-PCI of de novo oLCx lesions (isolated or in the context of a distal left main bifurcation) in eight international centers from 2018 to 2023 were retrospectively enrolled and compared with a historical cohort of patients who received PCI with DES.

Radial arteriovenous fistula (AVF) following radial intervention is exceedingly scarce. Here, we report a case of a 73-year-old man who was admitted with acute myocardial ischaemic syndrome and underwent transradial angioplasty of the proximal left anterior descending and circumflex artery. Fourteen months later, he presented with progressive swelling, dilated superficial veins, a palpable thrill, continuous bruit, and tingling at the local site.

Introduction: The profunda femoris artery (PFA) is the largest branch of the femoral artery supplying the thigh. The study reports a rare occurrence of bilateral double profunda artery in a male cadaver, aiming to inform surgeons of such variations to avoid complications during surgical interventions.
Methods: This study was conducted during routine dissections using 5-10% formalin-fixed lower limbs of a male cadaver at the Department of Anatomy, College of Medicine and Health Sciences, United Arab Emirates University, UAE.
