Rheumatic mitral valve repair or replacement in the valve-in-valve era.

Objective: For degenerative mitral disease, repair is superior to replacement; however, the best operative strategy for rheumatic mitral disease remains unclear.

We explored whether sex-related differences persisted among patients undergoing isolated coronary artery bypass grafting.

Methods: We undertook a prospective, observational study of 17,363 patients without dialysis (13,137 male: 75.
