We thank Moons and associates [1] for their thought-provoking letter on more rigorous methods to define quality of life after cardiac operations, which comments upon our study [2]. Clearly cardiac surgeons in general have thus far devoted limited efforts in the assessment of such an endpoint, being more focused on survival, major adverse cardiovascular events, and so forth. The issue becomes even more pertinent in patients who have grown into adulthood after pediatric cardiac repair.
In reply to the letter of Moons and colleagues [1], we would only like to make two comments. First, the definition of quality of life remains somewhat elusive. Although it is intuitive that self-perceived health and social status may be of primary importance, thus validating clinical research studies such as the ones by Moons and associates [35], objective measures of overall functional status (ie, activity) may be as important. Thus, the New York Heart Association or similar functional class scales, school attendance, employment status, and the ability to exercise should, in our opinion, never be underestimated. In fact, if we as clinicians can do only little to influence the perception our patients have of their health status, we can do a lot to affect their ability to physically function and interact with their peers. Second, the condition of grown-up with congenital heart disease (GUCH) is objectively and, most likely subjectively, somewhat different from the one of a young patient with chronic aortic valve disease, due to variability in disease severity. Therefore, as we agree that more appropriate methods to assess quality of life after the Ross procedure should be adopted, we are not entirely convinced that inferences drawn on GUCH patients should be transferred tout court to patients having cardiac valve operations.
