An anomalous aortic origin of a coronary artery is rare and surgical intervention is recommended when the patient is symptomatic. We performed coronary artery bypass graft surgery in a 21-year-old male patient with a right coronary artery anomalously originating from the left coronary sinus. The artery was significantly stenosed by external compression between the aorta and the pulmonary artery...

AIM Controversy exists concerning the relation between Helicobacter pylori (HP) infection and coronary artery disease (CAD). We aimed to examine the relationship between HP infection and severity of coronary atherosclerosis in patients with chronic CAD. PATIENTS AND METHODS A total of 150 patients (109 [73%] men; mean age 62.61±10.23 years) scheduled for coronary artery bypass grafting surger...

Vertebral artery hypoplasia (VAH) can be easily overlooked if the contralateral side vertebral artery is intact, because of compensation by the contralateral artery or cerebral collateral network. The clinical relevance and hemodynamic impact of VAH is still controversial. However, VAH has recently been considered a risk factor for posterior circulation ischemia. Ischemic stroke is seldom cause...

Abstract The paper deals with a theoretical study on blood flow in stenosed segment of an artery, when is mixed nano-particles. Blood treated here as couple stress fluid. Stenosis known to impede and be the cause different cardiac diseases. Since arterial wall weakened due stenosis, it may lead dilatation /aneurysm. homotopy perturbation technique employed determine solution problem for case mi...

This paper investigates the magnetic blood flow in an inclined multi-stenosed artery under influence of a uniformly distributed field and oscillating pressure gradient. The is modelled using non-Newtonian Casson fluid model. governing fractional differential equations are expressed by Caputo-Fabrizio derivative without singular kernel. Exact analytical solutions obtained Laplace finite Hankel t...

We report two female patients with Takayasu's aortoarteritis, who presented with symptoms of cerebral ischemia due to critical stenosis of the sole patent cerebral artery. Both had occlusion of both vertebral arteries and one carotid artery with critical stenosis of the other carotid artery and presented with hemiparesis contralateral to the patent but stenosed cerebral artery. They also had tr...

A 34-year-old, single Japanese woman with active Takayasu's disease presented with stenosed bilateral common carotid arteries, subtotal occlusion of the left subclavian artery, and complete occlusion of the ipsilateral proximal vertebral artery, as demonstrated by angiography. A right subclavian-Jeft vertebral bypass using an autologous saphenous vein graft was successfully performed after 36 d...

A 42 years, hypertensive lady presented with chest pain of 2 hours duration. On examination, her vital parameters were settled and there was no gross cardiovascular abnormality. Electrocardiogram showed acute anterior myocardial infarction. Troponin I was positive for myocardial necrosis. Transthoracic echocardiogram revealed hypokinetic left ventricular apex and apical half of interventricular...

Cerebral angiograms were performed in 14 children with sickle cell disease and clinical findings of cerebral infarction. The angiogram was normal in four patients. Ten patients had abnormalities in the carotid artery or its branches. The internal carotid artery was stenosed or occluded usually with bilateral disease. The anterior and middle cerebral arteries were involved in nine patients and b...

In this investigation, a mathematical model for studying oscillatory flow of blood in a stenosed artery under the influence of transverse magnetic field through porous medium has been developed. The equations of motion of blood flow are solved analytically. The analytical expressions for axial velocity, volumetric flow rate, pressure gradient, resistance to blood flow and shear stress have been...
