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.
