CLINICAL INTRODUCTION: A 59-year-old woman visited an outpatient cardiology clinic due to shortness of breath on exertion. Physical examination showed no significant abnormality of vital signs. A III/VI systolic murmur was heard on the fourth intercostal space at the right sternal border. The majority of laboratory tests were normal. Chest X-ray showed a curved vessel shadow (figure 1A). Initial transthoracic echocardiography showed abnormal blood flow into the inferior vena cava (IVC) in the subxiphoid long axis view (figure 1B) and mild right heart dilatation (online supplementary figure 1)...

Coronary arteriovenous (AV) fistulae are rare congenital anomalies and encompass a wide variety of communications between the coronary artery and the pulmonary or systemic vasculature. Symptoms depend on the presence and severity of myocardial malperfusion secondary to coronary artery steal phenomenon at rest or exertion. These fistulae are traditionally treated by open surgery. Endovascular therapy has been reported with the use of fibered coils. We report a case of a large left anterior descending (LAD) coronary artery to the main pulmonary artery fistula that was incidentally discovered during a pre-operative work up in a 28-year-old woman...

Objective To reach consensus on which complications of varicose vein treatments physicians consider major or minor, in order to standardize the informed consent procedure and improve shared decision-making. Methods Using the e-Delphi method, expert physicians from 10 countries were asked to rate complications as "major" or "minor" on a 5-point Likert scale. Reference articles from a Cochrane review on varicose veins were used to compose the list of complications. Results Participating experts reached consensus on 12 major complications: allergic reaction, cellulitis requiring intravenous antibiotics/intensive care, wound infection requiring debridement, hemorrhage requiring blood transfusion/surgical intervention, pulmonary embolism, skin necrosis requiring surgery, arteriovenous fistula requiring repair, deep venous thrombosis, lymphocele, thermal injury, transient ischemic attack/stroke, and permanent discoloration...

We present two cases of females in their 40s presenting with biventricular heart failure being the consequence of a large arteriovenous fistula. Both patients had undergone abdominal surgery several years prior to the heart failure event with the initial finding of moderate pulmonary hypertension and high-output heart failure. CT revealed a large arteriovenous fistula between the common iliac artery and vein which subsequently was closed percutaneously.

Arteriovenous fistula (AVF) is regarded as the best vascular access for chronic haemodialysis (HD). Still, AVF inherently causes significant haemodynamic changes. Although the necessity for vascular access despite its putative cardiovascular complications favours AVF creation in patients under chronic HD, one may question whether sustaining a functional AVF after successful kidney transplantation extends the haemodynamic threat. Small prospective series suggest that AVF ligation causes rapid and sustained reduction in left ventricular hypertrophy...

A patient came to our institution for evaluation and closure of suspected patent foramen ovale actively manifesting as cerebrovascular accident. Through further studies, we found the presence of a pulmonary arteriovenous fistula, which was subsequently and successfully closed through non-invasive percutaneous selective segmental pulmonary artery embolisation.

Congenital pulmonary arteriovenous fistulae occur as a result of abnormal blood vessel development in the lungs. Blood takes a short pass from the pulmonary artery to veins. Multiple pulmonary arteriovenous fistulae are a rare occurrence, especially when involving both lungs. Fistulae located at the edge are prone to rupture and bleeding. We discuss a case of a 15-year-old overweight male with multiple pulmonary arteriovenous fistulae successfully treated with wedge-shape excision via video-assisted thoracoscopic surgery...

A 74-year-old woman underwent abdominal computed tomography for screening, and a right large aneurysmal-type renal arteriovenous fistula (AVF) was found incidentally. The venous sac of the renal arteriovenous fistula was enlarged, and coil embolization was considered. To prevent severe complications such as coil migration, pulmonary embolism, and rupture during procedure, coil embolization was approached via both the feeding artery and the draining vein simultaneously, with balloon occlusion of the feeding artery...

Aneurysms associated with arteriovenous fistulas (AVFs) are rare but can cause significant morbidity. They are often diagnosed after rupture, pain, or embolization. We describe a unique case of a 35-year-old woman with a large iliac vein aneurysm related to an acquired AVF incidentally discovered on ultrasound during pregnancy. She had a diagnosis of "idiopathic" pulmonary hypertension for several years. This report details the diagnosis and treatment with an arterial stent graft that was effective in decreasing the size of the venous aneurysm and reversing the systemic changes associated with the disease...

Primary iliac venous aneurysm is an exceedingly rare abnormality that can be complicated by pulmonary embolism, thrombosis, and rupture. Here we report the case of an otherwise healthy 40-year-old man with a unilateral external iliac vein aneurysm without any evidence of an arteriovenous fistula, proximal stenosis, or obstruction, as reported on computed tomography. Pulmonary embolism was diagnosed using 99m Tc-macroaggregated albumin scintigraphy. To prevent life-threatening complications, we treated the patient with anticoagulant therapy and performed aneurysmectomy with reconstruction using a saphenous vein graft patch...

Recent applications of computational fluid dynamics (CFD) applied to the cardiovascular system have demonstrated its power in investigating the impact of hemodynamics on disease initiation, progression, and treatment outcomes. Flow metrics such as pressure distributions, wall shear stresses (WSS), and blood velocity profiles can be quantified to provide insight into observed pathologies, assist with surgical planning, or even predict disease progression. While numerous studies have performed simulations on clinical human patient data, it often lacks prediagnosis information and can be subject to large intersubject variability, limiting the generalizability of findings...

A 39-year-old Japanese woman was diagnosed with a pulmonary arteriovenous fistula (PAVF) complicated by paradoxical cerebral infarction during pregnancy. She received an inferior vena cava filter (IVCF), but it was difficult to indwell because of the risk of repeat thromboembolism via PAVF. Therefore, we temporarily occluded the pulmonary artery with a balloon to prevent free thrombi from reaching the IVCF. Detection and treatment of PAVF are recommended in fertile young women. Obstruction of the pulmonary artery trunk with a balloon catheter may be useful during IVCF removal in patients with untreated PAVF...

Introduction: Cryptogenic stroke is present in about 40% of ischemic stroke patients. Extracardiac shunt related to pulmonary arteriovenous fistula (PAVF) could be a rare potential risk factor for embolic stroke. Most PAVFs are multiple, congenital, and associated with hereditary conditions. On the other hand, isolated PAVFs are rare conditions and an uncommon cause of cryptogenic stoke. Case Report: We describe a case of a young woman without history of respiratory diseases or vascular risk factors, who presented with acute onset of transitory aphasia and right hemiplegia...

The formation of a fistula between the right pulmonary artery and the left atrium via a sac is a very rare cyanotic congenital cardiopulmonary defect. A fistula between the pulmonary artery and left atrium may cause cardiac failure in utero. It can safely be treated surgically and in selected cases closure can be performed with transcatheter insertion of a device. In this article, we present a case with a fistula between the right pulmonary artery and the left atrium that was considered unsuitable for transcatheter closure and was safely treated surgically...
