“…This study is one of the first to validate a third-generation portable machine for basic haemodynamic state assessment and is supported by previous research validating second generation portable echocardiography machines [10][11][12]. Errors in image analysis were more likely with small structures (such as the interventricular septum) than large structures.…”

Summary Miniaturisation of ultrasound equipment has led to the development of hand‐held echocardiography devices suitable for bedside evaluation of cardiac function. Basic assessment of the haemodynamic state can be performed using a limited transthoracic echocardiography examination. This study evaluated a third generation device (SonoSite Titan™) used by novice and expert operators. Limited transthoracic examination was performed on 30 healthy volunteers by an expert and a novice operator. The novice had performed 10 studies prior to data accrual. Agreement analysis was performed using weighted least products regression and Bland‐Altman analysis. Acceptable results for the novice were achieved following 20 studies (including practice sessions) for basic haemodynamic assessment and following 40 studies for all measured parameters. The SonoSite Titan is acceptable for basic transthoracic measurements to determine the basic haemodynamic state and cardiac output measurements. We recommend a minimum of 20 training studies for novice operators prior to clinical use.

“…In the arm that used HHU, we also added the average cost per use of the HHU unit, with total costs amortized over a HHU was also marginally superior to physical examination in excluding several miscellaneous findings but was far superior in terms of identifying these findings when they were present, although the accuracy of HHU was also not exemplary in this situation. favorably with the standard echocardiogram in terms of making cardiac measurements (7)(8)(9)(10)(11)(12) and the diagnosis of specific cardiac conditions (13)(14)(15)(16)(17)(18)(19)(20). These devices have also begun to be used to assist with vascular access (21) and removal of fluid from the thorax and pericardium (22).…”

“…Several previous studies reported that HCU showed good concordance of diagnostic capability with SED in terms of assessing LVEF and LV dimension measurement and detecting pericardial effusion and valve disease (4)(5)(6)(7)(8)(9) . Also, they are being placed in emergency or critical care settings to assist in the evaluation of hemodynamically compromised patients (10)(11)(12) .…”

Introduction: The purpose of this study was to compare the results of physical examinations (PEs) performed by a cardiologist with the results of point-of-care echocardiography for the diagnosis and management of patients during cardiac consultation rounds. Patients and Methods:In all, 265 hospitalized consecutive patients from non-cardiac units (age, 62 ± 11; male, 56%) were included after complete cardiovascular (CV) examination by a consulting cardiologist. After the PE, the consulting cardiologist imaged each patient using a hand-carried cardiac ultrasound (HCU). All patients subsequently underwent a study with a standard echocardiographic device (SED) as the gold standard, performed on an upper-end platform. Defi nitive diagnosis, management change, and modifying diagnostic workup were also assessed.Results: There were 196 CV fi ndings detected with an SED in this patient population. Of these, PE failed to detect 41% of the overall CV fi ndings and HCU missed 23% of the overall CV pathology. Overall, HCU had an effect on patient treatment decisions in 149 patients (56%); 42% had a change in medical therapy and 21% had a change in their diagnostic workup (most with changes in both). Conclusion:HCU echocardiographic assessment during consultation rounds improved the detection of signifi cant CV pathology. Also, a direct assessment of cardiac function and anatomy at the bedside by an experienced cardiologist with HCU as a routine adjunct to PE results in an important change in clinical management and diagnostic workup during consultation.Key Words: Hand-carried cardiac ultrasound; point-of-care screening Kardiyak Konsültasyonlar Esnasında Tanı ve Tedavide Taşınabilir Ekokardiyografi Cihazları ile Birlikte Fizik Muayenenin Karşılaştırılması ÖZETGiriş: Bu çalışmanın amacı, kardiyak konsültasyon esnasında tanı ve tedavi üzerinde ekokardiyografi sonuç-ları ile kardiyolog tarafından gerçekleştirilen fi zik muayene sonuçlarını karşılaştırmaktır.
