Hypoplastic left heart syndrome (HLHS) is a collection of inherent heart weakness that is characterized by multilevel obstruction of systemic cardiac output from the level of the mitral valve to the proximal descending thoracic aorta and hypoplasia of the left ventricle. A three-staged surgical repair or heart transplantation enough to Treatment of HLHS. It will typically require open-heart surgery to re-direct the oxygen-rich blood and oxygen-poor blood in a series of three reconstructive operations known as "Staged Reconstruction". Stage I,the Norwood procedure, and A few days of birth. Stage II, the Bidirectional Glenn or the HemiFontan, four to six months of birth. Stage III, the Fontan procedure, one-and-a-half to three years of age. Engineering sense go further to find the best design model using in each stage of medical solution, to became finally with battering design can result in long life compared with children have traditional way of surgery.So experiment had described the right ventricle and its function after treatment of HLHS.
