To the Editor:
We were delighted to read the article by Bohm et al1 addressing the potential deleterious impact of exercise on right ventricular (RV) function. This field definitely needs further study. The work was carried out by a renowned group. However, we were surprised by their conclusion “that the hypothesis of an exercise-induced ARVC needs to be questioned,”1 not only because the small study is underpowered but mainly because the conclusion is not supported by the findings.
The authors summed up 4 criteria by which to test the hypothesis. The first concerned the ratio of left ventricular end-diastolic volume/right ventricular end-diastolic volume (LVEDV/RVEDV). This test is indirect at best, only …
