Limitations
The study did not assess handheld echocardiography’s impact on altering patient management, changes in referral patterns, or healthcare expense utilization. The Vscan Extend evaluations were semi-quantitative and thus limited by the absence of continuous and pulse wave doppler, so VHD severity assessment relied only on Color Doppler and 2D assessment; therefore, we also could not evaluate pulmonary hypertension and diastology.
