1) Mitral valve stenosis; Criteria for the operation are at the stages of NYHA III or IV degrees and at the final stage of II degree. However we should operate at an early stage of II degree, if the restenosis occurs less by OMC than by CMC, because cerebral thromboembolism may happen in cases of I or II degrees. This, thromboembolization, caused by thrombos or calcification is also a future subject, because this may also happen after the operation. Restenosis is a problem too, because this may occur even after OMC.
2) Mitral valve regurgitation; Valvulo-plasty should be tried first before the heart muscle suffers seriously, but should the regurgitation continue, we must consider valve-replacement latterly. Artificial valves are expected to be safe and sound for 20 to 30 years without complications.
3) Aortic valve stenosis; Commissurotomy and debridment succeeded in solving most cases, but some themes are still left such as severe calcification or narrow ring.
4) Bacterial endocarditis; The protection before and after operation is still not solved.
5) Severely damaged heart; How to control the operative death and to prolong the long term survivals are remaining important themes.
