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
