Background/Introduction Congenital anomalies of the aortic arch gather a wide spectrum of malformations concerning the aortic arch or some of its branches and the pulmonary artery. These malformations are rare (1 in 1000 live births) and sometimes responsible of complete (vascular ring) or partial (vascular sling) encirclement of the oesophagus, trachea or bronchi. In cases of symptomatic airwa...

The rare anomaly of a right aortic arch, distal origin of the left subclavian artery, and posterior left ductus arteriosus (forming a vascular ring) plus a right ductus arteriosus is described in an infant with d-transposition of the great arteries with an intact septum. The presence of a right aortic arch and distal left subclavian artery with bilateral ductus arteriosus has not been described...

OBJECTIVES Platelets contain numerous substances regulating angiogenic response. However, the regulatory role of platelets in blood vessel development remains to be elucidated. We investigated the comprehensive effect of platelets as a cellular system on angiogenesis. METHODS The following approaches were applied: (a) in vitro-aortic ring assay and chemotaxis assay; (b) in vivo-injection of p...

Background  Transcatheter heart valve (THV) therapies have shown to be an alternative to surgical valve replacement, especially in high-risk patients requiring redo surgery. However, reports of transcatheter-based interventions in tricuspid valve position are scarce. Case Description  Here, we report a case of successful concomitant transcatheter aortic valve-in-valve (ViV) and tricuspid valve-...

Complete vascular rings are originated because of the persistence of the fourth aortic arches, which surround the trachea and esophagus partially or completely, compressing them. The most common type of complete vascular ring is the double aortic arch. Symptoms usually appear in the first months of life, and are provoked by esophageal and tracheal compression. The diagnosis is usually made thro...

The following is a description of a modified technique for the reinforcement of proximal anastomosis regarding the process of aortic allograft or pulmonary autograft full root implantation. A double width pericardial strip is used to create a pericardial sewing-cuff to be used as a neo-ring. This technique is said to be best suited for decreasing the operative bleeding, reducing anastomotic pit...

We report the case of a patient with situs inversus totalis, annuloaortic ectasia complicated by aortic insufficiency and mitral regurgitation which induced congestive heart failure. Both valvular lesions were repaired physiologically using aortic root sparing Yacoub 'remodeling' technique and mitral ring annuloplasty. Valve sparing techniques can be used effectively even in patients with compl...

Figure 2: (A, anterior view) Volume-rendering reconstruction from computed tomography scan revealed that the following branches were arising from the abnormal aortic arch: left common carotid artery, right common carotid artery, right subclavian artery and left subclavian artery. The left common carotid artery contributed to the partial vascular ring; however, there were no symptoms of trachea-...

A 2 year old girl is reported in whom deployment of the Amplatzer ductal occluder caused significant aortic obstruction, requiring surgical removal of the device. This case emphasises the need for careful echocardiographic and angiographic assessment of the position of the Amplatzer ductal occluder before and after detaching the device from its delivery system, with particular emphasis on the p...

BACKGROUND Modeling neo-aortic valve for arterial switch surgical planning to simulate the neo-aortic valve closure performance. METHODS We created five geometrical models of neo-aortic valve, namely model A, model B, model C, model D and model E with different size of sinotubular junction or sinus. The nodes at the ends of aorta and left ventricle duct fixed all the degrees of freedom. Trans...
