Contemporary trends in surgical rheumatic valve disease in a Caribbean nation

Clinical practice suggests that rheumatic heart disease (RHD) represents a significant public health challenge in the Caribbean region where advanced disease appears early often leading to surgical intervention. We aimed to determine the burden of RHD and type of procedure among patients undergoing valve surgery in the Dominican Republic (DR).

Demographic, clinical and procedural data of all subjects intervened between January 2014 and December 2018 were obtained including valve disorder, anatomic location and type of surgery. Correlation coefficients were used to assess yearly trends of RHD among the 7 cardiovascular surgical centers in the country.

Of 1626 valvular surgeries performed, 733 (45%) corresponded to RHD; 55% female patients, age 50 ± 11 (6-72) years; involving mitral 458 (63%); mitral + aortic 139 (19%); aortic 105 (14%); mitral + tricuspid 31 (4%); 95% prosthetic replacement and 5% mitral/tricuspid repairs. Mean proportion of RHD valve procedures per center for the study period was 53 ± 34%. Age-adjusted analysis showed an overall upwards trend in RHD valvular surgery (mean annual increment of 50 ± 40%, P = 0.01).

Despite inter-center variability, rates of surgical RHD in the DR increased during the last 5 years affecting a relatively young population. Mitral involvement was the predominant lesion and prosthetic replacement the leading procedure. These data may guide local and regional institutions and policy makers towards the implementation of cost-effective initiatives against RHD.
