What are the rate and clinical, surgical, and postoperative factors associated with unplanned 28-day index-hospital readmission in adults undergoing open-heart valve surgery?
Approximately 1 in 14 patients undergoing open-heart valve surgery in northeastern Thailand experienced an unplanned 28-day index-hospital readmission, driven primarily by anticoagulation complications and independently associated with mechanical valve implantation, postoperative acute kidney injury, and longer cardiopulmonary bypass duration.

May support closer post-discharge surveillance after valve surgery in patients with mechanical prostheses or AKI; extends risk factor data but leaves open need for trials.
To determine the rate of, and factors associated with, unplanned index-hospital readmission within 28 days of discharge after open heart valve surgery.

Sittiwong et al. (2026) conducted a cohort in Valvular heart disease undergoing open-heart valve surgery (n=1,336). Mechanical valve prosthesis implantation vs. Valve repair without a replacement prosthesis was evaluated on Unplanned index-hospital readmission within 28 days of discharge (aOR 3.98, 95% CI 1.97-8.25).
