Key result
Long-term valve-related complications following aortic valve prosthesis implantation occurred at 4.2/100 patient-years, with incidence significantly increased by high preoperative cardiothoracic index.

May warrant enhanced surveillance for patients with high preoperative cardiothoracic index; leaves open whether preoperative optimization reduces long-term valve-related complications.

What are the long-term complications and their preoperative predictors in patients with aortic valve prostheses?
Long-term complications following aortic valve replacement are significantly driven by preoperative patient characteristics, such as cardiothoracic index and NYHA class, rather than just the prosthesis itself.
Ole Lund (1988) conducted a cohort in Aortic valve prosthesis (n=139). Aortic valve prosthesis (Starr-Edwards silastic ball or cloth-covered) was evaluated on Overall rate of valve-related complications (VRC). Long-term valve-related complications following aortic valve prosthesis implantation occurred at 4.2/100 patient-years, with incidence significantly increased by high preoperative cardiothoracic index.
