REVIEW
Giovanni Filocamo, Sofia Torreggiani, Carlo Agostoni, Susanna Esposito
Granulomatosis with polyangiitis is an ANCA-associated systemic vasculitis with a low incidence in the pediatric population. Lung involvement is a common manifestation in children affected by granulomatosis with polyangiitis, both at disease's onset and during flares. Its severity is variable, ranging from asymptomatic pulmonary lesions to dramatic life-threatening clinical presentations such as diffuse alveolar haemorrhage. Several radiologic findings have been described, but the most frequent abnormalities detected are nodular lesions and fixed infiltrates...

A 62 year-old male with long-standing smoking history presented with hemoptysis. Plain chest x-ray showed abnormal findings proximate to the right pulmonary hilum. Bronchoscopy revealed a fragile exophytic tumor of the right wall of the lower third of the trachea, infiltrating the right main bronchus (75% stenosis) and the right upper lobar bronchus (near total occlusion). Contrast-enhanced chest CT demonstrated a 7.2x4.9 cm tumor contiguous to the above-mentioned structures, mediastinal lymph node pathology, and a vessel coursing inferiorly to the left of the aortic arch and anterior to the left hilum...

Acquired pulmonary vein stenosis is a rare cardiac defect and diagnosis can often be challenging, as many cases present with refractory or prolonged oxygen requirement over the expected course. Comorbid conditions can cloud this diagnosis further. Prognosis is poor for most patients. We present a case of idiopathic acquired pulmonary vein stenosis and discuss diagnostics, treatment options, and the need for further collaborative studies.

BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) and open splenectomy and esophagogastric devascularization (OSED) are widely used to treat patients with portal hypertension and recurrent variceal bleeding (PHRVB). This study aimed to compare the effectiveness between TIPS and OSED for the treatment of PHRVB. METHODS: The data were retrospectively retrieved from 479 cirrhotic patients (Child-Pugh A or B class) with PHRVB, who had undergone TIPS (TIPS group) or OSED (OSED group) between January 1, 2010 and October 31, 2014...

OBJECTIVES: Leftward displacement of the septum primum is usually described as associated with hypoplastic left heart syndrome or visceral heterotaxy. This rare malformation results in partially or totally anomalous pulmonary venous drainage with a normal connection of the pulmonary veins to the left atrium, depending on the degree of septal shift. We report the 3D echocardiographic and anatomic findings as well as the surgical repair in a series of isolated severe leftward displacement of the septum primum, responsible for totally anomalous pulmonary venous drainage...

Write a review text or point-of-view that takes into account the interests, if not of all, but of most readers of a scientific journal is an arduous task. The editorial can be grounded in published articles, even in a single article of undeniable importance and, it can also represent a trend of specialty. Therefore, especially for the sake of the reader's motivation, the present text was freely designed to discuss some cardiology enigmas in the context of the heart valve and coronary artery disease (CAD). Concerning the CAD five well-known enigmas will be considered: 1) The absence of arteriosclerosis in intramyocardial coronary arteries; 2) The unique and always confirmed superior evolution of the left internal thoracic artery as a coronary graft; 3) The prophylactic left internal thoracic artery graft in mildly-stenosed coronary lesions, and; 4) The high incidence of perioperative atrial fibrillation (AF) in patients with CAD, and; 5) The handling of disease-free saphenous vein graft at the time of reoperation...

Two English bulldogs referred for interventional palliation of severe pulmonary valve stenosis were incidentally diagnosed with unilateral absence of an external jugular vein (left in one case, right in the other) by computed tomography and Doppler ultrasound. The right internal jugular vein also could not be visualized in the dog with absence of the left external jugular vein. Cervical venous anomalies can impact diagnostic or interventional venous catheterization procedures such as balloon pulmonary valvuloplasty...

A 6-year-old boy presented with dual drainage of left upper pulmonary vein, with connection to innominate vein inaddition to its normal connection to the left atrium. Despite relief of aortic stenosis at the age of 3 years, significant left to right shunt persisted. The dual drainage allowed successful percutaneous closure of the levoatriocardinal vein without obstruction to the pulmonary venous flow to the left atrium.

Neurofibromatosis type I (NFI), also called Von Recklinghausen disease, is an autosomal dominant disease secondary to a genetic mutation on the long arm of chromosome 17. This disorder affects neural crest cells. Cutaneous clinical forms are the most frequent with multiple benign skin neurofibromas, associated with café au lait skin spots and iris hamartomas. Vascular abnormalities in NF1 are rare but have also been well described. The most frequent abnormalities are characterized by arterial aneurysm degeneration, stenosis, and malformations...

Deep vein thrombosis (DVT) with its major complication, pulmonary embolism, is a global health problem. Mechanisms of DVT remain incompletely understood. Platelets play a role in DVT, but the impact of specific platelet receptors remains unclear. Platelet C-type lectin-like receptor 2 (CLEC-2) is known to maintain the physiological state of blood vasculature under inflammatory conditions. DVT is a thromboinflammatory disorder developing largely as sterile inflammation in the vessel wall. We hypothesized therefore that CLEC-2 might play a role in DVT...

A pulmonary vein stenosis is a known adverse event of catheter ablation in atrial fibrillation. However, it should be considered due to high frequency of such procedures. Haemoptysis, a symptom of severe stenosis, is often misdiagnosed as other different diseases. We present a case report of a 52-year-old patient with recurrent haemoptysis, dyspnoea, and fatigue, which turned out to be complication after catheter ablation. Successful treatment with drug-eluting stent (DES) was implemented with vast clinical improvement and follow-up...

Rachel D Vanderlaan, Christopher A Caldarone
The sutureless technique has evolved from an effective treatment modality for postrepair pulmonary venous stenosis to a prophylactic strategy for primary repair of total anomalous pulmonary venous connection. Although conclusive data demonstrating efficacy as a universal prophylactic strategy is lacking, Zhang et al provide evidence that supports the sutureless technique as a safe and an effective prophylactic strategy in certain subsets of high-risk patients.
