JACC's February 17 issue gives readers a comprehensive focus issue on women's cardiovascular health, a long overlooked field of study. In this interview, JACC Associate Editor Makoto Mori, MD, joins resident Catherine M. Wagner, MD, MSc, to discuss her brief report on sex differences in tricuspid valve repair during mitral surgery, highlighting that women with moderate or severe tricuspid regurgitation are less likely than men to receive concomitant repair. The findings suggest that reliance on an absolute annular size threshold rather than an indexed threshold may contribute to undertreatment of women, as indexed measurements better reflect disease severity in smaller body sizes. The study emphasizes the need to move toward personalized, indexed criteria in surgical guidelines to reduce care gaps and improve outcomes for women.
