Minimization of the manipulation of the diseased ascending aorta has been shown to be associated with a reduced risk of postoperative stroke during coronary artery bypass surgery. We describe in this paper a novel method in which a single proximal anastomosis has been performed in the same ostium on the ...

Coarctation of the aorta is a complex vascular lesion that usually originates distal to the left subclavian artery. It accounts for 5-10% of all congenital cardiovascular malformations and carries a high morbidity and mortality risk. Symptoms depend on the severity of the disease and other coexisting anomalies. Early in life, ...

The combination of coronary artery disease and its complications (ischemic mitral regurgitation etc.) with the aneurysm of the descending thoracic aorta is not a rare case. The single-stage correction of coronary/intracardiac/aortic lesions may be considered as a way of managing the combined patients. Simultaneous multi-vessel coronary artery bypass grafting, suture ...

Extracellular matrix degradation and increased proteolytic enzyme (matrix metalloproteinase (MMP)) activity characterise abdominal aortic aneurysm formation. Post-stenotic dilatation of ascending aorta is associated with aortic stenosis and regurgitation, haemodynamically normal bicuspid aortic valve (BAV) and following AV replacement. We aimed to determine an association between ascending aortic pathology and abnormal ...

A newborn with pulmonary atresia, intact ventricular septum, and a bicommissural aortic valve underwent percutaneous pulmonary valvotomy at 1 day of age. Severe coarctation of the aorta became apparent only after spontaneous closure of the ductus arteriosus at 5 weeks of age, requiring repair by surgical end-to-end anastomosis. This is ...

Pseudocoarctation, also known as kinking or buckling of the aorta, is an uncommon anomaly. Its recognition is important, because it may be mistaken for true coarctation, aneurysm or mediastinal neoplasm. A case of pseudocoarctation associated with left cervical aorta is reported. The present case is unique in the demonstration of ...

OBJECTIVE: Ascending aortic aneurysms (AscAAs) are a highly lethal condition whose pathobiology remains to be poorly understood. Although most AscAAs occur in the presence of a trileaflet aortic valve (TAV), a bicuspid aortic valve (BAV) is a common congenital anomaly associated with an increased risk for an AscAA and dissection ...

The recent Kidney Disease: Improving Quality Outcomes (KDIGO) recommendations called for an investigation of the relationship between various radiological methods to assess cardiovascular calcification and measures of arterial stiffness. Accordingly, in 131 adult maintenance hemodialysis patients, we investigated the association of aortic pulse wave velocity (PWV) with calcification of cardiac ...

The Fibulins are a 6-member protein family hypothesized to function as intermolecular bridges that stabilize the organization of extracellular matrix structures. Here, we show that reduced expression of Fibulin-4 leads to aneurysm formation, dissection of the aortic wall and cardiac abnormalities. Fibulin-4 knockdown mice with a hypomorphic expression allele arose ...

Coarctation of the aorta may present in infants, children, or adults, and it requires treatment to prevent serious morbidity and mortality. Recent advances in equipment and a growing collective experience have made placement of balloon-expandable stents a safe and effective alternative to surgery or angioplasty in a growing range of ...

BACKGROUND: Side clamping to perform saphenous vein-to-aorta proximal anastomosis is a well known cause of cerebral embolization during coronary bypass surgery. Automatic and manual devices have been introduced to avoid aortic clamping and facilitate proximal anastomosis but the manual ones only allow the traditional hand-sewing running suture. Nevertheless, they are ...

The management of patients with aortic coarctation and ventricular septal defect (VSD) remains controversial. A 2-stage repair uses staged coarctation repair +/- pulmonary artery banding followed by VSD closure with 2 separate operations. This has the advantage of a straightforward coarctation repair (except in the case of proximal arch hypoplasia) ...
