Isolated left subclavian artery is one of the rarer aortic arch anomalies. It has been associated with other congenital heart diseases, typically tetralogy of Fallot, double-outlet right ventricle, and atrial and ventricular septal defects. Its significant clinical implications include a left-to-right shunt from the vertebrobasilar system, which causes pulmonary overcirculation and subclavian steal. We present an unusual case of a premature infant who was diagnosed prenatally with congenital complete atrioventricular block and tricuspid atresia and was found to have an isolated left subclavian artery postnatally...

: Persistent respiratory or feeding problems in children may be associated with a congenital vascular ring. Surgical management is fairly standardized, but long-term outcomes are not well described. This study aims to investigate clinical presentation, surgical treatment, and risk factors for early mortality and late outcome. Our database revealed 62 surgically treated vascular ring patients between 1993 and 2014. Double aortic arch was the most common diagnosis (53%). Median age at operation was 1 year...

Although cardiac malformations at birth are typically associated with genetic anomalies, blood flow dynamics also play a crucial role in heart formation. However, the relationship between blood flow patterns in the early embryo and later cardiovascular malformation has not been determined. We used the chicken embryo model to quantify the extent to which anomalous blood flow patterns predict cardiac defects that resemble those in humans, and found that restricting either the inflow to the heart or the outflow led to reproducible abnormalities with a dose-response type relationship between blood flow stimuli and the expression of cardiac phenotypes...

REVIEW
Charles D Fraser
The neonatal arterial switch operation has become the standard of care for transposition of the great arteries, including transposition with intact ventricular septum, transposition with ventricular septal defect with or without aortic arch hypoplasia, and double outlet right ventricle with subpulmonary ventricular septal defect (Taussig-Bing anomaly). While technically demanding, the operation is enormously gratifying and exciting for the congenital heart surgeon. In the current era, outcomes and expectations for the neonatal arterial switch operation are extremely high with many centers, including our own, reporting 30-day or hospital survivorship approaching 100%...

We hypothesised that infants with ventricular dysfunction after cardiac surgery have impaired haemodynamic response to arginine-vasopressin therapy. We retrospectively reviewed the medical records of neonates and infants treated with arginine-vasopressin within 48 hours of corrective or palliative cardiac surgery who underwent echocardiographic assessment of ventricular function before initiation of therapy. Patients were classified as "responders" if their systolic blood pressure increased by ⩾10% without increase in catecholamine score or if it was maintained with decreased catecholamine score...

OBJECTIVES: Complete vascular rings are rare and cause tracheoesophageal compression. Following surgical division, some patients have persisting tracheomalacia. We aim to assess the long-term outcomes of complete vascular ring division. METHODS: All patients (n = 132) who underwent surgical division of a complete vascular ring between 1978 and 2014 were identified from the hospital database and retrospectively reviewed. RESULTS: Complete vascular rings consisted of a double aortic arch (n = 80), right aortic arch with an aberrant subclavian artery and left ligamentum arteriosum (n = 50), right aortic arch with mirror image branching and left ligamentum arteriosum (n = 1), and a left aortic arch with right descending aorta and right ligamentum arteriosum (n = 1)...

: Thoracic aortic aneurysms are now routinely repaired with endovascular repair if anatomically feasible because of advantages in safety and recovery. However, intraoperative aneurysm rupture is a severe complication which may have an adverse effect on the outcome of treatment. Comprehensive preoperative assessment and considerate treatment are keys to success of endovascular aneurysm repair, especially during unexpected circumstances. Few cases have reported on intraoperative aortic rupture, which were successfully managed by endovascular treatment...

BACKGROUND: Scleroderma is a chronic connective tissue disorder with unknown etiology. It is characterized by excessive deposition of extracellular matrix in the connective tissues causing vascular disturbances which can result in tissue hypoxia. These changes are manifested as atrophy of the skin and/or mucosa, subcutaneous tissue, muscles, and internal organs. Such changes can be classified into two types, namely, morphea (localized) and diffuse (systemic). Morphea can manifest itself as hemifacial atrophy (Parry-Romberg syndrome) although this remains debatable...

Toll-like receptor 4 (TLR4) is important for the pathogenesis of inflammatory reactions and the promotion of pain processing after ischemia/reperfusion (IR) in spinal cord. Recently, C-X-C chemokine ligand 12 (CXCL12) and its receptor, C-X-C chemokine receptor 4 (CXCR4), were demonstrated to be simultaneously critical for inflammatory reactions, thereby facilitating glial activation. However, whether CXCL12/CXCR4 expression can contribute to IR-induced inflammatory pain via spinal TLR4 remained unclear. A rat model was established by 8 min of aortic arch occlusion...

The successful clinical introduction of various non-invasive imaging modalities has contributed to the establishment of 'acute aortic syndrome', a relatively new clinical syndrome incorporating several disease entities with similar clinical features (at the time of clinical presentation). Aortic dissection (AD) with intimal flap and two aortic channels (true and false lumens) is the most important disease entity in acute aortic syndrome. Clinical characteristics of AD have been established, with standardized treatment strategies depending on the affected site of the aorta...
