Transposition of the great arteries (TGA) is a cardiac condition in which the arterial trunks arise from the inappropriate ventricle: the aorta from the right ventricle and the pulmonary trunk from the left ventricle [discordant ventriculo-arterial (VA) connection]. In complete TGA, the discordant VA connection is associated with situs solitus or inversus and concordant atrioventricular (AV) connection. The hemodynamic consequence of these combined connections is that systemic and pulmonary circulations function in "parallel" rather than in "series"...

Renal arteriovenous (AV) shunt, a rare pathologic condition, is divided into two categories, traumatic and nontraumatic, and can cause massive hematuria, retroperitoneal hemorrhage, pain, and high-output heart failure. Although transcatheter embolization is a less-invasive and effective treatment option, it has a potential risk of complications, including renal infarction and pulmonary embolism, and a potential risk of recanalization. The successful embolization of renal AV shunt requires a complete occlusion of the shunted vessel while preventing the migration of embolic materials and preserving normal renal arterial branches, which depends on the selection of adequate techniques and embolic materials for individual cases, based on the etiology and imaging angioarchitecture of the renal AV shunts...

Rendu-Osler-Weber disease, also known as hereditary haemorrhagic telangiectasia, is a genetic disease characterized by an autosomal dominant transmission that causes multiple angiodysplasic lesions, and multiple arteriovenous malformations. Among these, pulmonary arteriovenous malformation is the most common, and is found in approximately 70% of patients that suffer from this syndrome. In a representative population sample, it is recognized that 90% of the patients that have a pulmonary arteriovenous malformation suffer in fact from Rendu-Osler-Weber disease...

INTRODUCTION: Aortopulmonary collateral arteries are an uncommon variant of alternative blood supply in cases of complex congenital heart disease. Although surgery may still be the classic approach for this condition, mini-invasive endovascular occlusion has been recently attempted as an alternative less traumatic procedure. Children born to women with epilepsy are at increased risk of congenital malformations. CASE PRESENTATION: A cardiovascular malformation in a 6-year-old white boy with prenatal exposure to carbamazepine is described...

BACKGROUND: Scimitar syndrome can present with a wide clinical spectrum of symptoms either early in the neonatal period or later in life. CASE DESCRIPTION: We report a case of a 62-year-old woman with anomalous systemic arterial supply to the basal lung with scimitar syndrome presenting as recurrent hemoptysis. Bronchoscopy revealed normal major bronchial branches without bronchial atresia, indicating that sequestration of the lung was not confirmed. The anomalous drainage of the scimitar vein was to the inferior vena cava, and an anomalous artery from the aorta supplied the right basal lung...

Pulmonary arteriovenous malformation (PAVM) is a rare clinical condition with abnormal direct communication between the branches of pulmonary artery and vein. It may occur as an isolated anomaly or in association with hereditary hemorrhagic telangiectasia (HHT). Although these vascular pulmonary pathologies are quite uncommon, they are the important part of the differential diagnosis of common pulmonary problems such as hypoxemia and pulmonary nodules. The diagnosis of PAVM in patients remains a diagnostic challenge to the emergency physician...

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal-dominantly inherited vascular-malformation syndrome associated with gene mutations including ENG, ACVRL1 and SMAD4 gene. Clinically indistinguishable HHT1 and HHT2 are caused by mutations in ENG and ACVRL1 gene, respectively. Generally, pulmonary arteriovenous malformations (PAVMs) and pulmonary arterial hypertension (PAH) are rare manifestations of HHT related to ACVRL1 gene mutations. We described a female patient with HHT2 whose clinical features included epistaxis, mucocutaneous telangiectases, systemic AVMs and PAH...

PRINCIPLES: To assess the efficiency and complication rates of vaso-occlusion of pulmonary arteriovenous malformations (PAVMs) in Rendu-Osler-Weber disease (hereditary haemorrhagic telangectasia; HHT). METHODS: Seventy-two patients were investigated in our institution for HHT between March 2000 and November 2011. Sixteen presented PAVMs (22.2%), and 11 (68.8%) were treated with vaso-occlusion for a total of 18 procedures. Procedures included coils, plugs and combined approaches...

Although the association between patent foramen ovale and ischemic stroke is controversial, the evaluation for a right-to-left shunt remains part of the standard workup for cryptogenic stroke. Transthoracic and transesophageal echocardiogram (TTE and TEE) are the screening test and gold standard to evaluate for right-to-left shunt, respectively. Studies comparing TTE or TEE to transcranial Doppler (TCD) have shown that 15-25 % of patients test positive for right-to-left shunt on TCD but are negative on TTE or TEE...

Hereditary haemorrhagic telangiectasia is a rare systemic autosomal dominantly inherited disorder of the fibrovascular tissue with a wide variety of clinical manifestations. Diagnosis is based on the clinical Curaçao criteria or molecular genetic testing. Dilated vessels can develop into telangiectases or larger vascular malformations in various organs, calling for an interdisciplinary approach. Epistaxis and gastrointestinal bleeding can result from these vascular defects. Various conservative and interventional treatments have been described for these conditions...

A 50-year-old female visited the hospital for further evaluation of multiple pulmonary and hepatic nodules. First, she visited her primary physician for general fatigue due to anemia. She had recurrent epistaxis, and her mother had suffered from hereditary hemorrhagic telangiectasia (HHT). Telangiectasias were present in the stomach. This patient was diagnosed with HHT. Computed tomography (CT) revealed multiple pulmonary and hepatic nodules. The pulmonary nodules were due to bleeding from arteriovenous malformations of the lung...

A vein of Galen arteriovenous malformation (VGAM) is a rare intracranial shunt lacking a capillary bed and resulting in subsequent aneurysmal enlargement. VGAM has been previously reported to present as cardiovascular abnormalities, including increased right-sided cardiac load and pressure, cardiac dilatation, pulmonary hypertension and retrograde flow into the aortic arch. We report the first case of VGAM presenting as a gross right-sided neck swelling in a 39-week-old immediately at birth. Transthoracic echocardiography detected dilatation of the superior vena cava and innominate vein, increased right ventricular and pulmonary arterial pressure, and retrograde flow into the aortic arch...

Arteriovenous malformation (AVM) is a rare vascular anomaly of the lung, which manifests predominantly as dyspnea (due to right to left shunting) and paradoxical embolism. Hereditary Hemorrhagic Telangiectasia (HHT) being a rare genetic disorder is one of the most common causes of pulmonary arteriovenous malformation (PAVM). Here we report an interesting case of recurrent anemia in an elderly female, who was subsequently found to have multiple cutaneous and mucosal telangiectasias and a large pulmonary AVM.

While the Fontan operation is a reliable treatment option for many complex congenital heart defects, the development of pulmonary arteriovenous malformations (PAVMs) remains a problematic outcome for some Fontan patients. Pulmonary arteriovenous malformations stem from an imbalance of hepatic blood flow in the pulmonary system. Balancing this hepatic flow has shown promising results in the treatment of PAVMs. We report the clinical course of a young patient with heterotaxy syndrome and an unbalanced right dominant atrioventricular septal defect...

The expectoration of blood originating from the lower respiratory tract, called hemoptysis, is a common clinical condition with many potential etiologies. Massive hemoptysis is life threatening and needs urgent intervention. Multidetector computed tomography (MDCT) is a useful non-invasive imaging modality for the initial assessment of hemoptysis. Using MDCT with multiplanar reformatted images has improved the diagnosis and management of hemoptysis by providing a more precise depiction of bronchial and non-bronchial systemic arteries than conventional computed tomography (CT)...

Alveolar adenoma is an extremely rare benign tumor of the lung derived from type II pneumocytes. To date, only a limited number of alveolar adenoma cases have been reported in the literature. These tumors are usually discovered incidentally on radiographic images. However, other tumor types must be excluded when the characteristics of alveolar adenoma are not typical on the radiographic images. Therefore, diagnosis of alveolar adenomas is based on the combination of gross structural analysis and immunohistochemistry...
