Dear Editor,

We would like to share ideas on “Estimation of postmortem interval by postmortem myocardial computed tomography (CT) value.[1]” An et al. concluded that “This study initially realized the feasibility of using myocardial CT value changes to estimate PMI, indicating that myocardial CT value can be used as one of the evaluation indicators for PMI estimation.[1]” We agree that postmortem myocardial CT value might be useful. However, it is necessary to have further studies to validate confounding effects. Important concerns include the effect of underlying cardiac abnormalities (such as old myocardial infarction MI) and infection. In a previous study, low sensitivity of postmortem myocardial CT for diagnostic cardiac pathology is also reported and experience of the radiologist is required for interpretation of result.[2] A combination with an invasive heart autopsy approach or an image-guided biopsy is always required.[2] In addition, in a tropical climate, putrefaction might occur quickly, affecting the myocardial CT value. If possible, An et al. might provide a clinical association with local temperature and can further correlate to chronological change. Finally, if postmortem CT is employed, stringent contamination and infectious disease controls must be in place.
