Echocardiographic findings in patients with COVID-19 ARDS. A Non-survivor patient. (Αi) non-survivor with RV dilation on ICU admission; (Aii) PAcT: 64.6 ms Red arrows indicate the early systolic notch in the ascending part of the RVOT envelope. Please not the triangular spahe of the RVOT envelope indicating increased PVRs. (Aiii) RV dilatation upon re-evaluation; (Aiv) TRV: 3.6 m/sec ≥ PASP = 51.81 mmHg + (CVP: 13 mmHg) = 64.25 mmHg (Av) TAPSE: 1.6 cm (re-evaluation); (Avi) PAcT: 42 ms Red arrows indicate the early systolic notch in the ascending part of the RVOT envelope. Please not the triangular spahe of the RVOT envelope indicating increased PVRs. B Survivor patient. (Bi) survivor with RV dilatation upon ICU admission; (Bii) PAcT: 76.75 ms Red arrows indicate the early systolic notch in the ascending part of the RVOT envelope. Please not the triangular spahe of the RVOT envelope indicating increased PVRs, (Biii) normal size of the RV upon re-evaluation; (Biv) TRV: 2.54 m/sec ≥ PASP = 25.82 mmHg + (CVP: 8 mmHg) = 33.82 mmHg (Bv) TAPSE: 2 cm; (Bvi) PAcT: 95 ms, Please not the normal parabolic shape of the RVOT envelope in indicating normal PVRs.
