Right aortic arch with associated arch hypoplasia, coarctation, and an aberrant isolated left subclavian artery is a very uncommon variant of vascular rings, which itself accounts for fewer than 1% of all congenital cardiac defects. Several cases have been reported, and most commonly, extraanatomic grafts have been used for repair. ...

Aortic pseudoaneurysms are rare but life-threatening complications of aortic procedures. Operation on the femorofemoral bypass with hypothermic circulatory arrest has been the method of choice. Iatrogenic ascending aorta pseudoaneurysm combined with infective endocarditis of the aortic valve has never been reported. We describe a case of a pseudoaneurysm of the ...

This study aims to assess the mid- to long-term follow-up of patients after valve embolization at the time of transcatheter aortic valve implantation (TAVI). Transcatheter heart valve (THV) embolization is a rare but serious complication during TAVI. Although various techniques have been developed to manage acute complications and reduce periprocedural ...

CXCR7 (RDC1), a G-protein-coupled receptor with conserved motifs characteristic of chemokine receptors, is enriched in endocardial and cushion mesenchymal cells in developing hearts, but its function is unclear. Cxcr7 germline deletion resulted in perinatal lethality with complete penetrance. Mutant embryos exhibited aortic and pulmonary valve stenosis due to semilunar valve ...

Hypoxic pulmonary vasoconstriction (HPV) is driven by the intrinsic response to hypoxia of pulmonary arterial smooth muscle and endothelial cells. These are representatives of a group of specialized O2-sensing cells, defined by their acute sensitivity to relatively small changes in pO2, which have evolved to modulate respiratory and circulatory function ...

Most neonates with clinically significant pulmonary hypertension (PH) will have either persistent PH of the newborn (PPHN) or bronchopulmonary dysplasia. Cyanotic congenital heart disease must be actively ruled out as part of the differential diagnosis of PPHN. The maintenance of ductal patency with prostaglandins E1 or E2 in cases of ...

Abstract The limits of traditional anticoagulants, such as heparin and warfarin, have prompted the search for new agents for prophylaxis and treatment of arterial and venous thromboembolism, including factor Xa and thrombin inhibitors. These agents can be given orally, and their most significant advantage is that no laboratory monitoring is ...

Arterial baroreflex and cardiac autonomic control play important roles in hemodynamic instability after carotid artery stenting (CAS). Spontaneous baroreflex sensitivity (BRS), heart rate variability (HRV) and blood pressure variability (BPV) are established tools for the assessment of arterial baroreflex and cardiac autonomic activity. Aim of the study was to evaluate ...

Sudden cardiac death in congenital heart disease is related to increased right ventricular end-diastolic volume (RVEDV), abnormalities of QRS duration, and QRS, JT, and QT dispersions. Surgical pulmonary valve replacement and percutaneous pulmonary valve implantation (PPVI) decrease RVEDV, but the effects of PPVI on surface electrocardiographic parameters are unknown. PPVI ...

Patients with stenosed biologic pulmonary conduits require redo cardiac surgery to prevent severe right ventricular dysfunction. Following the latest trends, the trans-catheter pulmonary stent-valve implantation represents a new fascinating alternative carrying a lower operative risk, compared with the standard open-heart re-intervention. Traditionally, the pulmonary stent valve is positioned off pump, ...

A 26-year-old male presented with radiographical evidence of enlargement of the right side of the heart. Echocardiography and computed tomography-scan revealed a diffuse, hugely enlarged right coronary artery (RCA) aneurysm, with the distal portion flowing directly into the left ventricle (LV). A radical correction operation was performed successfully. The RCA ...
