We present here the fourth patient in the literature, over the age of 50 years old, with an abnormal right coronary artery arising from the pulmonary artery, who was successfully treated with surgery. Pre-operative computerised tomography (CT) angiography revealed an abnormal right coronary artery arising from the pulmonary artery. The ...

Percutaneous transcatheter aortic valvuloplasty is seriously limited by high restenosis rates. We report a case where the use of a buddy-catheter technique during balloon inflation allowed increased focused force onto calcified stiff commissures with an increase in resultant valve area. This technique may result in further valve area enlargement and ...

A 69-year-old lady was discovered unconscious. Computed tomography showed pericardial effusion and a coronary artery aneurysm of 25 mm in diameter in front of the main pulmonary artery. Emergency surgery revealed a coronary-pulmonary artery fistula and coronary aneurysm surrounded by a large hematoma. The inflow and outflow of the fistula ...

Although the use of heterogeneous overlapping drug-eluting stents (DES) is not uncommon in clinical practice, whether the implantation sequences of heterogeneous DES will influence the endothelialization or arterial responses differently remains unclear. Twenty-one rabbits were randomized to receive overlapping stents in the iliac artery for 3 months {distal sirolimus-eluting stent ...

The incidence of multivessel coronary artery ectasias (CAEs) among patients undergoing coronary artery angiography is very rare. All three coronary vessels can be affected by CAE, but most patients have an isolated arterial ectasia, commonly the right coronary artery. In this report we present two cases with inferior myocardial infarction ...

The blood supply to the medulla oblongata is distinct from that of other areas of the brainstem, and thus the mechanism underlying medullary infarctions may be distinct. However, few studies have investigated this. Of 3833 stroke patients who were on the stroke registry between February 1999 and April 2008, those ...

Intravascular ultrasonography (IVUS) has been shown as a valuable adjunct imaging tool during endovascular procedures but its value in detection of any recurrence during follow up after endovascular coil embolization of large and giant intracranial aneurysms is not reported. A 41 years old man who had been treated using stent ...

Large artery stiffness, as measured by pulse wave velocity, is correlated with high blood pressure and may be a causative factor in essential hypertension. The extracellular matrix components, specifically the mix of elastin and collagen in the vessel wall, determine the passive mechanical properties of the large arteries. Elastin is ...

Vascular calcification can occur in nearly all arterial beds and in both the medial and intimal layers. The initiating factors and clinical consequences depend on the underlying disease state and location of the calcification. The best studied manifestation is coronary artery calcification, in part because of the obvious clinical consequences, ...

Aim: Late occlusion of bypass grafts is one of the main issues associated with long-term survival after coronary artery bypass grafting (CABG) surgery. Left coronary system is generally revascularized using arterial conduits, whereas saphenous venous grafts are used for right coronary system. We investigated the prognostic factors that are related ...

A dilated and tortuous fistula from circumflex coronary artery draining into the right atrium was diagnosed by transthoracic echocardiography and selective angiography in a 64-year old female. Transcatheter closure was excluded by the cardiologist because of the presence of a large huge at the drainage site so the patient was ...

Large elastic arteries and smaller muscular conduit arteries become stiffer with ageing, a process that is accelerated in the presence of cardiovascular disease (CVD). In recent years, numerous techniques have been developed to measure arterial stiffness, either in single vessels or in entire muscular arterial trees. These techniques have increasingly ...

Repair of chronic Type B aortic dissection can be technically challenging. Here we describe a technique for the partial replacement of the descending thoracic aorta that minimises operative risk and avoids full replacement of the thoraco-abdominal aorta. This approach can be considered when there is heterogeneous perfusion of abdominal viscera ...

Calcific aortic valve disease is the most common heart valve disorder. So far, there is no medical treatment for calcific aortic valve disease. The expression of ectonucleotidases, which metabolize nucleotides into phosphate products, may influence the calcification of the aortic valve. In this study, we investigated if the administration of ...

Total arterial compliance (C(T)) is a main determinant of cardiac afterload, left ventricular function and arterio-ventricular coupling. C(T) is physiologically more relevant than regional aortic stiffness. However, direct, in vivo, non-invasive, measurement of C(T) is not feasible. Several methods for indirect C(T) estimation require simultaneous recording of aortic flow and ...

Positioning the parturient from supine to the left lateral tilt position (supine-to-tilt) may not effectively displace the gravid uterus, but turning from the left lateral position to the left lateral tilt position (left lateral-to-tilt) may keep the gravid uterus displaced and prevent aortocaval compression. Fifty-one full-term parturients were randomly placed ...

Abstract  The prevalence of coronary artery disease in patients with aortic aneurysm is high. As an antecedent percutaneous coronary intervention with antiplatelet therapy may cause a rupture of aortic aneurysm, concomitant treatment for aortic arch aneurysm and coronary artery disease is recommended. We report a technique of a combined procedure ...

BACKGROUND: Carotid artery stenting (CAS) is an alternative to carotid endarterectomy (CEA) for revascularization of the internal carotid artery (ICA). CAS from the femoral approach may be problematic due to peripheral vascular disease, anatomical variations of the aortic arch, and access site complications. The purpose of the present study was ...

Purpose: The standard approach in patients with a clotted arteriovenous fistula (AVF) on the forearm is the creation of another vascular access on the arm using the patient's own vessels or a prosthetic graft. Here we propose another option as secondary angioaccess for chronic hemodialysis (HD): superficialization of the radial ...
