It is known from other areas of medicine that \"prehabilitation\" - a short, structured exercise programme completed before surgery - can improve fitness and help patients cope better with major operations. However, this approach has never been tested in adults with CHD. The investigators are running a randomised controlled trial to find out whether a prehabilitation programme can improve physical fitness before heart surgery in adults with CHD.\n\nParticipants will be randomly assigned to usual care or a prehabilitation group. Those in the prehabilitation group will follow a tailored, supervised exercise plan for several weeks before surgery.\n\nAll patients undergoing cardiac surgery routinely complete a cardiopulmonary exercise test (CPET) as part of their standard pre-operative assessment. CPET is a well-established test that shows how the heart and lungs respond to increasing levels of exercise. During the test, participants exercise on a bike while their breathing, heart rate, and overall physiological response are continuously monitored.\n\nThe results of each participant's routine CPET will be used to guide the individualised exercise programme in the intervention group.\n\nExercise levels prescribed in the study will not exceed the intensity already safely achieved during the routine CPET, ensuring that activity remains within clinically assessed limits.\n\nParticipants in the trial will complete an additional second CPET following the trial period.\n\nThe key question is whether a tailored exercise programme can improve fitness in adults with CHD before heart surgery, and whether this approach is feasible, acceptable and practical to deliver, including successful recruitment and measurable physiological improvements.",[59,60],"Congenital Heart Disease","Cardiac Surgery",[62,63,64],"Congenital heart disease","Prehabilitation","Cardiac surgery","NOT_YET_RECRUITING","2026-07-21",{"date":68,"type":69},"2026-07-22","ACTUAL",{"date":71,"type":53},"2026-08-10",{"date":73,"type":53},"2029-06-01",{"name":5,"class":6}]
