Despite recent advances in cardiac imaging technology, routine use of hand-carried ultrasound (HCU) device in the contemporary practice of cardiovascular medicine has not been adopted. We hypothesized that HCU device is superior to the physical exam (PE) by cardiologists and complements the initial assessment.
We prospectively enrolled 250 in- and outpatients over 26 months who received a standard 2D and Doppler transthoracic echocardiogram (TTE) for acceptable clinical indications. All participants received a limited bedside ultrasound using the VScan (GE Healthcare) and a PE, which were performed by randomly assigned cardiologists with variable levels of experience. Diagnoses were adjudicated based on TTE
McNemar's test was used to compare findings in 4 groups: left ventricular systolic dysfunction, valve disease, pulmonary hypertension, and miscellaneous (aortic, pericardial, pleural, and congenital disease).
The median age of 164 males and 86 females was 60.9 ±15.4 years. The mean scan time was 8.2 ± 3.1 minutes, and PE duration was 5 ± 3 minutes. HCU device was exceptionally superior to PE in detecting pathology (Table 1). No significant difference was seen in HCU exam or PE among the cardiologists.
HCU is vastly superior to PE even when used by cardiologists. Routine incorporation of HCU device into the PE facilitates early and accurate diagnosis of cardiac pathology, which can result in efficient delivery of care and potentially reduce cost.
