Mitral Valve aka Bicuspid
Mitral Valve aka Bicuspid Valve
Human Anatomy & Physiology II

The left atrioventricular valve, with two cusps, is called the mitral valve because it resembles the two-sided bishops miter or hat. It is sometimes called the biscuspid valve. (Marieb & Hoehn, 2007). This valve separates the left atrium of the heart from the left ventricle of the heart. It prevents the back flow of oxygenated blood to the pulmonary circuit. Heart valves are simple devices, and the heart – like any mechanical pump – can function with “leaky” valves as long as the impairment is not too great. However, severe valve deformities can seriously hamper cardiac function. (Marieb & Hoehn, 2007). The mitral valve (bicuspid valve) can be replaced successfully by means of surgical intervention. New research is being developed to engineer tissue grown from the patient’s own cells to replace the defective mitral valve. Barik, Ramachandra, Patnaik, A.N.,Mishra, Ramesh C., Kumari, N.

Heart surgery of any sort is a delicate procedure. This procedure was performed for multiple disorders of the heart and circulation. The patient presented with a combination of both congenital and acquired cardiac defects. The diagnosis included congenital bicuspid aortic valve, aortic regurgitation juxta-subclavian coarctation, stenosis of the left subclavian artery and ruptured sinus of the valsalva aneurysm. This combination of defects is very rare. The patient was weakened by the severity of the defects and the multiple disorders. It was decided to perform the corrective procedure in one surgery. The surgery was performed for this patient without complications. Management of this type of cardiac

    PROCEDURE: The right groin was prepped and draped in the usual fashion. Seldinger technique was used, and a 6-French sheath was placed in the right femoral artery. A local anesthetic was used and sublingual nitroglycerin was given; no heparin was used. The left and right coronary arteries were selectively opacified in the LAO and RAO projections using manual injections of Optiray. A ventriculogram was done in the RAO projection with the use of a 6-French pigtail catheter. The catheters were then withdrawn, the sheath was removed and VasoSeal applied, and the patient was sent to her room in good condition without complications. PRESSURES: Aorta 117/63, LV 110/2-6…

    ~ 2 AV valves are located at each atrial-ventricular junction, prevent backflow into the atria when the ventricles are contracting. : 1) Tricuspid Valve-the right AV valve has 3 flexible cusps. 2) The Mitral Valve-the left AV valve with 2 flaps. It is sometimes called the bicuspid valve because of its resemblance to the 2-sided bishop’s miter or hat. Attached to each AV valve flap are tiny white collagen cords called CHORDAE TENDINEAE, “heart strings” which anchor the cusps to the papillary muscles protruding from the ventricular walls. When the heart is completely relaxed, the AV valve flaps hang limply into the ventricular chambers below & blood flows into the atria and then thru the open AV valves into the ventricles. When the ventricles contracts, compressing the blood in their chambers, the intraventricular pressure rises, forcing the blood superiorly against the valve flaps. As a result, the flap edges meet, closing the valve.…

    Once the incision has been made, carefully open the heart. You should be able to view the left atrioventricular valve (bicuspid), the right antrioventricular valve (tricuspid), the aortic valve, and the pulmonary valve. The aortic valve will be just superior to the pulmonary valve and both are smaller in size compared to the left and right AV valves. The aortic valve is where the aorta…

    Aortic valve stenosis is when the aortic valve narrows and cannot fully open. This causes an obstruction of blood flow to the body. Ms. W has two options which are choose to have the surgery or wait until she’s ready to have the surgery, which will be in a year. The surgery is necessary because the risk of delaying surgery can cause problems such as chest pain, syncope, arrhythmias and even heart failure. Valve replacement surgery is an invasive open-heart surgery which would improve blood flow and quality of life. Ms. W could also ask her cardiologist about the possibility of having a less invasive procedure such as transcatheter aortic valve replacement (TAVR). This procedure is when a catheter with a balloon tip is inserted into the patient’s…

    There are two types of aortic valve diseases: regurgitation and stenosis. Aortic regurgitation is a condition in which blood flows backward from a weak or widened aortic valve into the heart’s left ventricle. Aortic Stenosis is a narrowing or blockage of the aortic valve. This happens with the valve leaflets become coated with deposits. Since this is makes the aortic valve smaller, the left ventricle has to work harder in order to get the same amount of blood through the small opening, over time, this extra work can weaken the heart. There are three mitral valve diseases: mitral valve prolapse, mitral regurgitation, and mitral stenosis. Mitral valve prolapse disease is where one or both of the valve flaps (cusps or leaflets) are enlarged and the flaps’ supporting muscles are too long; instead of closing evenly, the one or both of the flaps collapse or bulge into the left atrium. Mitral regurgitation is caused by earlier conditions that have weakened the heart, such as if a person has had a heart attack or had rheumatic fever as a child. Mitral stenosis is a narrowing or blockage of the mitral valve, the narrowed valve causes blood to back-up into the heart’s upper-left chamber instead of flowing into the lower-left chamber. Atrial septal defect, also known as ASD, is a “hole” in the wall that separates the top two chambers of the heart. Ventricular septal defect (VSD), is the opposite of ASD, it is a hole in the wall separating the two lower chambers of the heart. Tetralogy of fallot is a combination of four different problems: a hold between the lower chambers of the heart, the muscle surrounding the lower right chamber becomes overly thickened, an obstruction from the heart to the lungs, and when the aorta is over the hole in the lower chambers. These are a few of the heart conditions that a cardiothoracic surgeon…
