| Popis: | Pediatric heart transplant patients (PedHtx) require frequent monitoring by echocardiography (echo); however, they often live far from hospitals with pediatric echo services, resulting in urgent/emergent transfers to specialized institutions. Our primary objective was to evaluate the feasibility of parental acquisition of echo images to assess left ventricular (LV) systolic function in PedHtx using a handheld echo device. Secondary objectives included retesting for skill maintenance and in patients with decreased LV systolic function.During a routine clinic visit, parents received 1-hour training with a handheld echo device to acquire images in parasternal short-axis and apical views. Parents recorded images on their children at training completion and 24 hours later at home. An independent echocardiographer assessed clinic, training, and home echos for LV systolic function.Fifteen PedHtx (mean age of 12.6 years of age; range, 4.1-16.7) were enrolled. All parents could acquire home images adequate for qualitative assessment of LV systolic function with no discrepancy compared with clinical echos. LV ejection fraction (LVEF) could be calculated (5/6 area-length method) in 86% of training and 43% of home echos with10% difference in LVEF measurements between home and clinic echos. Five parents repeated home echos12 months later. All home echos were adequate for qualitative assessment of LV systolic function (LVEF measurable in two). Additionally, five heart failure patients with decreased LV systolic function (mean age of 8.6 years; range 1.9-15.1) were enrolled. All home echos were adequate for qualitative assessment of LV systolic function (LVEF measurable in one).Our results suggest that parental home echo acquisition using a handheld echo device is feasible and adequate for qualitative assessment of LV systolic function in PedHtx. However, quantitative assessment of LV systolic function, especially in patients with dysfunction, and retention of the skill set without additional training are suboptimal. |
