The images presented here are from a 44-year-old asymptomatic man. At age 36 years, he experienced nonsustained atrial fibrillation. A year later, a transthoracic echocardiogram disclosed an enlarged left ventricle (diastolic dimension, 7.4 cm; ejection fraction, 56%) and a very large coronary sinus with Doppler color flow evidence of diastolic and systolic turbulence consistent with entry of a...

BACKGROUND Right-sided aortic arch is a rare congenital defect usually diagnosed incidentally in adults; it is often asymptomatic unless aneurismal disease develops. In half the cases, an aberrant left subclavian artery arises from a Kommerell's diverticulum; in these cases, congenital heart anomaly is very rarely present. CASE PRESENTATION We report a case of incidentally-detected right-side...

Arteriovenous fistulas of the placenta are extremely rare in singleton pregnancies and, to our knowledge, have not previously been reported in twin gestations. We describe a case of an arteriovenous fistula of the placenta in a diamniotic-monochorionic twin pregnancy complicated by twin-to-twin transfusion syndrome (TTTS). The arteriovenous fistula was demonstrated by color-coded vascular injec...

BACKGROUND Spinal dural AVF is the most common type of spinal vascular malformation. However, presenting symptoms differ according to site of spinal involvement. This study described a case of arteriovenous malformation with paraparesis and incontinence. CASE PRESENTATION Diagnosis of patient was confirmed by clinical and imaging examination using magnetic resonance image and ruling out other...

INTRODUCTION An arteriovenous fistula (AVF) is an abnormal connection between an artery and a vein which may result from traumatic injury or may occur as congenital abnormality. Stent graft repair through arteriovenous fistula could lead to complications. CASE REPORT Endovascular stent graft repair in a 23-year-old patient with posttraumatic superficial femoral arteriovenous fistula was perfo...

Arteriovenous fistulas have long intrigued cardiologists, in part because they are uncommon but also because of their physiologic effects, both local and general. For instance, a fistula in an extremity in children enhances growth of that extremity, whereas a fistula located in the kidney can cause systemic hypertension. Besides local effects, systemic arteriovenous fistulas, if large, have maj...
