Key result
Elective valve surgery at a low-volume LMIC center shows ~3.3% 30-day mortality.
Why the study?
Valvular heart disease carries significant prevalence and mortality, prompting an evaluation of outcomes after heart valve surgery in a low-volume center in a low- and middle-income country.
Cross-Sectional (n=122)
No
Heart valve surgery performed at a low-volume center in a low- and middle-income country is feasible and associated with acceptable short- and mid-term mortality rates.
Supports feasibility of valve surgery at low-volume LMIC centers; leaves open generalizability beyond this single-center experience.
Background: Valvular heart disease (VHD) has a significant prevalence and mortality rate with surgical intervention continuing to be a cornerstone of therapy. We aim to report the outcome of patients undergoing heart valve surgery (HVS) in a low-volume center (LVC) in a low- and middle-income country (LMIC). Methods: A cross-sectional retrospective study was conducted at the Jordan University Hospital (JUH), a tertiary teaching hospital in a developing country, between April 2014 and December 2019. Patients who underwent mitral valve replacement (MVR), aortic valve replacement (AVR), tricuspid valve replacement (TVR), double valve replacement (DVR), CABG + MVR, and CABG + AVR patients were included. Thirty-day and two-year mortalities were taken as the primary and secondary outcomes, respectively. Results: A total number of 122 patients were included, and the mean age was 54.46 ± 14.89 years. AVR was most common (42.6%). There was no significant association between STS mortality score or Euroscore II with 30-day and 2-year mortality. Conclusion: LVC will continue to have a role in LMICs, especially during development to HICs. Further global studies are needed to assert the safety of HVS in LVC and LMICs.

Hani et al. (2023) conducted a cross-sectional in Valvular heart disease (n=122). Heart valve surgery was evaluated on 30-day mortality. Elective heart valve surgery performed at a low-volume center in a low- and middle-income country was associated with a 3.3% 30-day mortality rate and a 4.1% 2-year mortality rate.
