Primary pulmonary artery sarcoma is an uncommon neoplasm with a grim prognosis. Complete resection is the only treatment that can improve the patient's survival. The role of multimodality treatment is still controversial, although adjuvant chemotherapy possibly could improve outcomes of these patients. Several pulmonary artery reconstructive techniques have been reported ...

Valve replacement is typically the most appropriate option for treating aortic valve stenotic insufficiency. However, neither mechanical nor bioprosthetic replacement components preserve the circumferential expansion and contraction of a native aortic annulus during the cardiac cycle, because the prosthetic ring is affixed to the annulus. A 64-year-old man presented with ...

Since 2000, transcatheter pulmonary valve replacement has steadily advanced. However, the available prosthetic valves are restricted to bioprosthesis which have defects like poor durability. Polymeric heart valve is thought as a promising alternative to bioprosthesis. In this study, we introduced a novel polymeric transcatheter pulmonary valve and evaluated its feasibility ...

Earlier studies have indicated that bovine left common carotid artery configuration occurs in 10.2-22% of patients and increases the complexity of navigating endovascular devices in the aortic arch. However, we anecdotally noted a higher incidence of bovine arch among angiosuite outpatients in Los Angeles, California. Thus, we retrospectively reviewed aortic ...

Hyperaldosteronism is linked to the development and progression of several different cardiovascular diseases. Angiotensin (Ang) II increases aldosterone secretion and adrenal blood flow. Ang II peptide fragments are produced by various peptidases, and these Angs have diverse and vital physiologic roles. Due to the uncharacteristic vasorelaxation of adrenal arteries by ...

Polytetrafluoroethylene (PTFE) grafts are commonly used for construction of the right ventricle-to-pulmonary artery conduit in the modified Norwood procedure. Dehiscence of a PTFE conduit in the setting of purulent mediastinitis presents a challenging clinical problem because of limited availability of appropriately sized replacement vascular homografts. The Contegra bovine jugular vein ...

Carotid artery dissections are commonly associated with trauma or various connective tissue disorders. Dissection of the cerebrovascular arteries can result in ischemic stroke and is a frequent stroke etiology in younger patients. Anatomical variants of aortic arch branching, such as the 'bovine' aortic arch, are assumed to have little or ...

Mitral valve insufficiency is frequently the result of elongated or ruptured chordae tendineae. Several techniques have been described for its correction. However, when there is a severe elongation or rupture of the chordae, the most widely accepted treatment option has been valve replacement. The best long-term outcomes observed in conservative ...

The angiosome model was first pioneered by Jan Taylor in 1987 by his influential anatomical works in the plastic reconstructive surgery field. The concept depicts the human body into three-dimensional blocks of tissue, fed by specific arterial and venous irrigation sources, the "angiosomes". Adjacent angiosomes are linked by a vast ...

Thromboendarterectomy remains a high-risk procedure. The use of circulatory arrest as a technique to allow pulmonary artery visualization is associated with cerebral and organ damage secondary to the ischaemic insult. Application of techniques learned from thoracic aortic stenting and minimal invasive valvular surgery may mean that circulatory arrest becomes an ...

Percutaneous intervention is becoming an increasingly recognised modality for the management of prosthetic paravalvar leaks (PVLs) with particular utility in severely symptomatic non-surgical candidates. To date, application of this intervention has predominantly involved closure of mitral valve PVLs. Consequently, current literature on its application to aortic PVLs is limited. This ...

Members of the growth factor family of neurotrophins [NTs; e.g. brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT3)] and their high-affinity receptors (tropomyosin-related kinase; Trk) and low-affinity receptors p75 neurotrophin receptor (p75NTR) have been localized to pulmonary artery (PA) in humans. However, their role is unclear. Based on previous findings of NTs ...
