In the absence of valve-related death and morbidity, and retention of good haemodynamic function, the PU valve was superior to the bioprosthesis; lower HITS and aggregate counts in the PU valve imply lower thrombogenicity compared with the mechanical valve. A biostable polyurethane valve could offer clinical advantage with the promise of improved durability (cf. bioprostheses) and low thrombogenicity (cf. mechanical valves).

Although most patients report improved health and well-being after coronary artery bypass operation, many have described their recovery and rehabilitation as a complex process with both short and long term effects. The insights provided by participants help improve our understanding of the impact of the operation on patients' health and well-being over time. We believe these insights will help us to anticipate the possible needs of future patients and enable us develop appropriate interventions that may facilitate self-management for optimal recovery and health maintenance.
