undergoing mitral valve surgery. (2, 3) LAA clipping is a new US FDA approved technique which has been increasingly used to exclude the LAA from the circulation during cardiac surgery in patients who have atrial fibrillation or have high CHADS2 risk score.(2-4,) The atrial clip has usually been deployed via median sternotomy incision. (4-7) Herein we examine the safety and feasibility of epicardial clipping the LAA via mini-thoracotomy approach during minimally invasive mitral valve surgery. Method

These valves are designed to control the direction of blood flow through the heart. The opening and closing of these valves produce the heart beat sounds. When the heart beats, the valves close to keep the blood form flowing backwards. The heart beats more than one hundred thousand times per day. The valves must be able to flex, stretch and hold back pressure hundreds of million times in an average lifetime. The mitral and aortic valves are on the left side of the heart

Mitral Valve Prolapse Michele Tolliver Body Systems, LRC Class #1 October 7, 2014 The flow of blood through the heart is controlled by four valves. If any are not working correctly, blood cannot flow or be pumped effectively to the heart. The four valves are: the tricuspid, pulmonary semilunar, mitral, and aortic semilunar. There are many abnormalities or defects that can affect their operation and in this paper, I will discuss the most common one which is a “mitral valve prolapse.” A valvular

AORTIC STENOSIS Calcific or degenerative aortic valve disease is considered one of the most, if not the most, common valvular lesion encountered among elderly patients.( Iung B, Baron G, Butchart EG, et al.) In fact, as shown in the Helsinki Aging Study, 501 randomly selected people, men and women, in an age range from 75 to 86 underwent echocardiography. (Iivanainen AM, Lindroos M, Tilvis R, et al) The outcome of the research was that, the prevalence of critical aortic stenosis increased with age

My name is Karmele Sagarzazu, I 'm the second of a family of three kids. I was born in a hard working Venezuelan-Basque family in Caracas, Venezuela. In this application I hope to demonstrate not only the academic and professional qualifications that make me an exceptional candidate to XXX University 's Master 's program in Refinery Design and Operation and to your scholarship, but also the personal characteristics that will allow me to obtain the most from studying at XXX University. As mentioned

is a very pleasant 50-year-old man who was referred for ongoing dyspnea on exertion. He states that his symptoms began about a year ago and at that time, he had extensive cardiac evaluation, which reveals significant mitral valve regurgitation for which he has mitral valve repair. Since that time, however, he states that his level of cardiovascular fitness has not returned to his previous baseline. He is here today for formal evaluation. It should be noted that he did have a right heart catheterization

Heart valves are tissue paper thin membranes attached to the heart wall that constantly open and close to regulate blood flow. The heart has 4 valves: Mitral and tricuspid valve, which control blood flow from the atria to the ventricles and aortic and pulmonary valve, which control blood flow out of the ventricles. A normal, healthy heart valve minimizes any obstruction and allows blood to flow smoothly and freely in one direction. It closes completely and quickly, not allowing any blood to flow

Artificial heart valve is a device implanted in the heart of a patient with valvular heart disease. When one of the four heart valves malfunctions, the medical choice may be to replace the natural valve with an artificial valve. This requires open-heart surgery. Valves are integral to the normal physiological functioning of the human heart. Natural heart valves are evolved to forms that perform the functional requirement of inducing unidirectional blood flow through the valve structure from one chamber

Mitral Valve Prolapse Clinical Mitral valve prolapse (MVP) was first characterized by Barlow and Bosman in the 1960s.(Barlow and Bosman) It was first called Barlow’s Syndrome before being called mitral valve prolapse by Criley (Barlow and Bosman),(Criley et al.). Barlow’s syndrome was diagnosed by electrocardiogram, phonocardiogram and chest X-ray.3 The mitral valve apparatus includes tow leaflets, chordae tendineae, anulus, left atrium, papillary muscles and left ventricular wall (Devereux
