From: Long-term outcome of a dilated cardiomyopathy patient after mitral valve surgery combined with tissue-engineered myoblast sheets—report of a case

(2-1) Ultrasonography revealed that the EF declined after MVR and was preserved for 6 years after myoblast sheet transplantation. (2-2) Ultrasonography showed that the LVDs expanded after MVR and was generally preserved 6 years after myoblast sheet transplantation. In particular, 2 and 3 years after cell sheet transplantation, the LVDs were notably reduced, and the LVDs showed re-dilatation 4 years after cell sheet transplantation. (2-3) Exercise tolerance test revealed a notable elevation in the VO2 1 year after cell sheet transplantation, and this improvement was preserved for 6 years after transplantation compared with the pre-transplantation value. (2-4) A 6-min walk test demonstrated that the walking distance was preserved for 6 years after cell sheet transplantation compared with the pre-transplantation value, despite an initial drop 3 months after the operation. (2-5) The patient was NYHA class III before MVR, which was improved to class II. This improvement was preserved for 6 years after cell sheet transplantation. (2-6) After MVR, the PAP was notably decreased, and this improvement was maintained for 6 years after cell sheet transplantation. (2-7) After MVR, the PCWP was also notably improved, and this improvement was preserved for 6 years after cell sheet transplantation. (2-8) After MVR, the serum BNP was notably decreased, and it gradually improved after cell sheet transplantation and was preserved for 6 years
