We describe three alternative approaches for the left ventricular assist device (LVAD) outflow graft during implantation of the LVAD. The supraceliac abdominal aorta, innominate artery and left axillary artery were employed as alternative sites for the LVAD outflow graft in the setting of a heavily calcified ascending aorta or a hostile chest wall and mediastinum. The first approach involved th...

Endogenous superoxide anion (O(-)(2)) interferes with the bioactivity of nitric oxide (NO) in endothelium-dependent arterial relaxation (EDR). Using the lucigenin chemiluminescence assay, we measured O(-)(2) in the thoracic and abdominal aortas and the carotid artery of rabbits to determine whether ambient O(-)(2) varies among the three arteries and differentially diminishes the effect of NO. B...

To the Editor: A 38‐year‐old male presented with chest pain for coronary angiography to exclude coronary heart disease in the Second Affiliated Hospital of Nanchang University. During coronary angiography, a 6 Fr sheath was inserted without any difficulty after right radial artery access was obtained. However, the Loach guidewire could only be advanced to the descending aorta, and repeated atte...

BACKGROUND AND OBJECTIVES Several studies have demonstrated a significant difference between the aortic and radial artery pressures in patients on cardiopulmonary bypass (CPB). The objectives of this study were to evaluate the behavior of the aorta-to-radial artery pressure gradient during myocardial revascularization (MR) with CPB and its correlation with the systemic vascular resistance. ME...

conclusions in most cases, the conus artery can be visualized in cardiac ct. a description of the conus artery should be a part of the standard clinical coronary ct angiography description. objectives to examine whether it is possible to visualize the conus artery in multi-slice computed tomography (ct). patients and methods in 79 consecutive patients (aged 56 ± 12.9 years; 13 women), 64-slice ...

The surgical management of porcelain aorta in patients requiring aortic valve replacement or coronary artery surgery carries a high morbidity and mortality and remains controversial. We report a successful transapical aortic valve implantation in combination with on-pump coronary artery bypass grafting in a young patient with severe aortic stenosis, left main coronary artery disease and porcela...

BACKGROUND We report on a case of an impar umbilical artery (IUA) in an 18-year-old woman. CASE PRESENTATION The aorta branched off at level L2 into a ventral IUA and a dorsal aorta. The strong IUA produced the inferior mesenteric artery (IMA), the renal artery of a left-sided duplex kidney, and the right-sided ovarian artery before it turned to the right to merge into the right common iliac ...

Introduction: Aneurysmal degeneration in patients with chronic type B dissection is common, occurring 20% – 40% of cases, which 10% develop late rupture. Open surgery for these cases associated high morbidity and mortality. Endovascular alternatives include fenestrated or branched endografts, although the use devices may be complex. Treatment usually involves implantation a device true lumen ob...

Twenty-one patients with anomalous coronary artery origin from the aorta are discussed, and the cases reported in the literature are reviewed. The left anterior descending (LAD) and left circumflex (Cx) arteries arose aberrantly from the right sinus of Valsalva of the aorta (RSV) in six patients. In four of these patients the connecting branch from the anomalous origin passed anterior to the ao...

Figure 1: CT images. (A) Preoperative three-dimensional CT image. Dextrocardia was observed preoperatively. The branches of the aortic arch were mirror-image reversed. (B) Postoperative three-dimensional CT image. Reconstructed aorta and branches were also mirror-image reversed. RV: right ventricle; Ao: aorta; BCA: brachiocephalic artery; Rt.SCA: right subclavian artery; Rt.CCA: right common ca...
