FEASIBILITY OF TELE-GUIDED PATIENT-PERFORMED LUNG ULTRASOUND IN PATIENTS WITH HEART FAILURE

TOPIC: Imaging TYPE: Original Investigations PURPOSE: B-lines on lung ultrasound are an early finding in patients with decompensated heart failure. Hence, monitoring failure their home environment could help to prevent hospital admissions. The aim of this project is investigate whether tele-guided patient-performed the feasible. METHODS: Stable ambulatory NYHA class 1-3 were included study. Patients received a hand-held probe connected tablet (patients 1 3) or smartphone. Initial instructions given during either clinic visit remote visit. each performed between 10 and 12 daily sessions, interrupted by weekends occasional days unavailability. During session, guided via verbal visual remotely physician. Over side chest, 3 locations within 3rd intercostal space examined, moving from mid-clavicular line anterior mid axillary line. also reported weight level dyspnea, graded 5-point scale. Ultrasound clips reviewed two independent reviewers, as interpretable if pleural plus at least one A-line any visible. Gain depth appropriate inappropriate. RESULTS: Eight patients, 2 them female, total 89 sessions. There no major technical problems, 88% (reviewer 1) 84% 2) all interpretable. A 92% 90% exams had 4 out 6 clips. Inter-reviewer agreement was substantial 93% observations Cohen’s Kappa 0.7. More than 97% gain settings. No patient abnormal exam, none admitted for exacerbation. Most (6 8) stable dyspnea scores throughout. score more 3% above dry weight. CONCLUSIONS: Tele-guided High quality obtained, evidenced being diagnostically usable decompensations observed, false positive recorded. To determine technology can be used detect decompensations, unstable need longer study period. CLINICAL IMPLICATIONS: This have far-reaching diagnostic implications, not just patients.
