Sever Aortic Stenosis (AS) is a major cause of mortality and morbidity in elderly duo to a bimodal age distribution ,degenerative calcification of Tricuspid valve is the major cause of AS in the population ,unlike the younger patient etiology which is : bicuspid valve calcification or rheumatic heart disease .1
The Burden of the disease is high with a prevalence of 3.4% 2. With the progressive nature of the disease and the increased severity of the symptoms made the surgery the gold standard for symptomatic AS patients ,however up to 30% of cases are considered too high risk for classical valve replacement surgery and remain untreated and experiencing poor prognosis . Fortunately , with the introduction of TAVR its offer a valuable option for the inoperable or at high risk of surgery patients3..the annual eligible candidate for this procedure expected to be 27,000 in 19 European countries and North America according to recent meta-analysis an...

- “Heart valve disease” refers to the potentially life-threatening condition in which a patient’s heart valves do not operate properly. One cause of heart valve disease is regurgitation, in which some amount of backflow is present, causing hemodynamic problems. However this type of condition most often affects the mitral valve, and its treatment has evolved to avoid valve replacement in favor of reparative techniques2, 4. For the aortic valve, the most common type of dysfunction is aortic stenosis, in which the flaps of the heart valves can no longer open fully, and not enough blood is able to pass through....

- Medtronic (Minneapolis) and Edwards Lifesciences (Irvine, California) were not strangers in patent lawsuits. Edwards is specializing in the production of artificial heart valves and new hemodynamic monitoring technology, whereas Medtronic is specializing in the production of medical devices. In the past, the two companies have problems in patent infringement lawsuits over annuloplasty procedures and endovascular graft (1,2). However, currently another latest patent infringement lawsuit has been occurred and reported between Medtronic and Edwards Lifesciences.... [tags: Heart Valves. Hemodynamic Monitoring Technology]

- Addressing Issues with Thrombosis and Investigating Backflow in the Bileaflet Mechanical Heart Valve (St. Jude Medical Valve) Introduction The past six decades have fostered the rise of remarkable innovations in the design and production of mechanical heart valves that are safe and hemodynamically favorable. The mechanical heart valves have been used widely over this time with the successful implantation of over 100,000 Omni-Brand tilting-disc valves and 300,000 Hall-Brand tilting-disc valves since the late 70's ....

- Aortic stenosis is a narrowing of the aortic valve. The aortic valve is a gate-like structure that is located between the lower left chamber of the heart (left ventricle) and the blood vessel that leads away from the heart (aorta). When the aortic valve is narrowed, it does not open all the way. This makes it hard for the heart to pump blood into the aorta and causes the heart to work harder. The extra work can weaken the heart over time and may lead to heart failure. Aortic stenosis can range from mild to severe.... [tags: Heart, Cardiology, Blood, Health care]

- Unit 1 Task sheet 4 Heart Atria: the atrium is one of the two blood collection chambers of the heart. It has a thin-walled structure that allows blood to return to the heart. Ventricles: a ventricle is one of two large chambers that collect and expel blood from an atrium. Bicuspid Valve: bicuspid valves play a crucial role in ensuring the unidirectional flow of blood from the atrium to the ventricles. Tricuspid Valve: The tricuspid valve is on the right dorsal side of the mammalian heart.... [tags: Blood, Heart, Blood vessel, Vein]

- Background Prosthetic heart valve replacement is performed in several hundred thousand patients per year worldwide and is recommended for many patients with severe valvular heart disease. Bioprosthetic heart valves and mechanical heart valves are the two major valve types. Mechanical valves are more durable than bioprosthetic valves but require lifelong anticoagulant therapy with vitamin K antagonists (warfarin) due to persistent risk of thrombosis and stroke. Warfarin has a narrow therapeutic window and requires frequent monitoring such as international normalized ratio (INR) and restrictions on food, drugs and alcohol....

- Fragmented QRS (fQRS) is a relatively novel indicator of non-homogeneous ventricular activity caused by myocardial scar (1). Fragmented QRS is simply defined as additional spikes within QRS complexes, such as a RSR', without a typical bundle-branch block pattern (2). Previous studies revealed that fQRS is related with depolarization anomalies and fibrosis in patients with ischemic cardiomyopathy (3-5). It was also associated with increased mortality and arrhythmic events in Brugada syndrome and arrhythmogenic right ventricular dysplasia (6-8).... [tags: aortic stenosis, cardiology, heart failure]

- R.S. is a 40 year old male with a diagnosis of aortic stenosis. R.S. was having aortic valve replacement surgery. When I finally was able to meet the patient he was with the CRNA. The CRNA was inserting an arterial line to left forearm and was uncomfortable through the procedure. Patient had and 18 gauge IV catheter noted to left antecubital. I came and introduced myself after the CRNA was done and asked if he would allow me to follow A.Hicks RN into his surgery. The patient was very pleasant and said yes....
