Reducing the wait: TCV can expand the donor pool for heart transplant candidates

Nicholas A Szugye et al. Pediatr Transplant. 2021 Jun.

Abstract

A 16-year-old with new-onset dilated cardiomyopathy underwent VAD placement, later complicated by low flow from outflow graft kinking. To expedite heart transplantation, TCV was calculated and compared with 141 normal patients pinpointing the upper weight threshold. He was transplanted 2 days later within the expanded weight range with no post-transplant complications.

Keywords: CT; TCV; heart transplantation; pediatric; pediatric heart transplantation; size matching.

Figure 1:
The TCV segmentation is shown in the axial plane (A), coronal plane (B), and 3-dimensional reconstruction (C). TCV mass is in Red and HMIII is in green. Abbreviations: TCV; Total Cardiac Volume, HMIII; Heartmate III.

Figure 2:
The recipient TCV segmentation (red) overlaid with predicted donor heart TCV (yellow) is shown in multiple planes (A), and in a 3D reconstruction. Other structures are the implanted HM3 device (green), superior vena cava (blue), pulmonary arteries in purple. (B) A best fit line of weight vs. TCV in the normal population (black dots) with the 95% confidence interval (dotted line). The measured recipient TCV (red diamond) is larger than all normal TCVs and the predicted donor TCV (yellow square).
