A numerical analysis was completed on the influence of plaque on the compliance of an artery wall. The analysis allowed a systematic variation of the transluminal pressure difference and plaque thickness. Included in the analysis was a sheath of surrounding tissue that provides support during the cyclical deformation. The analysis incorporated progressively thicker layers of plaque to quantify their impact on the artery compliance.
Background: Autonomic nerve innervation pathway from the ventricular GP to the pulmonary veins (PV) remains unclear.
Aim: This study investigates the autonomic innervations from aortic root ventricular GP to the PVs. Nissl's staining and fluorescent dual label staining were performed to determine the neuron structure in the aortic root GP in five dogs. Avidin Biotin Complex (ABC) staining were performed to study the efferent autonomic pathway from the aortic root GP to the PVs.
Coronary artery aneurysm (CAA) is defined as abnormal dilatation of a coronary artery luminal diameter to 1.5 to 2 times wider than the adjacent normal segment. Giant coronary artery aneurysms are rare, with a reported prevalence of 0.02% to 0.2% [1].
Infective endocarditis is a potentially fatal infectious disease which usually presents with various clinic scenarios. Although the disease generally presents itself with fever, cardiac murmur (bruit), splenomegaly and anemia; in this case we report a double valve endocarditis of a 23 years-old female patient who was admitted to our neurology clinic with acute ischemic stroke.
Atrial myxomas are the most common primary cardiac tumors to diagnose. They are benign and have variable presentation. They have an excellent prognosis following surgical excision. We report a case of a 60 year old female who presented with initial signs of both right and left heart failure, fever and cough. Auscultation of the heart revealed an apical mid diastolic murmur. Trans-thoracic and trans-esophageal echocardiography revealed a pedunculated, giant left atrial myxoma that prolapsed through the mitral valve into the left ventricle in diastole producing functional mitral valve stenosis. The patient underwent a successful surgical excision of the tumor. The diagnosis and management of atrial myxomas is here reviewed.
