BACKGROUND
A pocket-sized portable transthoracic echocardiographic (pTTE) imaging device is commercially available, but its feasibility and accuracy in the assessment of cardiac chamber size and function has not been fully compared with the results of standard TTE (sTTE) examination.
METHODS AND RESULTS
The target population comprised 125 unselected patients who underwent sTTE and pTTE examinations. The left ventricular (LV) diastolic and systolic dimensions, fractional shortening (FS), the thickness of the interventricular septum (IVS) and of the LV posterior wall (PWT), left atrial (LA) dimension, and ascending aorta diameter were measured. Echocardiographic measurements were completed for both pTTE and sTTE in all patients (feasibility 100%). LV dimensions, FS, IVS, PWT, LA dimension, and aorta diameter obtained by pTTE showed excellent correlation and agreement with sTTE (r=0.87-0.98, all P<0.001). Observer variabilities for these measurements were similar between pTTE and sTTE.
CONCLUSIONS
In the present study, pTTE with the Acuson P10 was feasible and accurate for assessing cardiac chamber size and function.
背景
一种袖珍便携式经胸超声心动图（pTTE）成像设备已上市，但在评估心腔大小和功能方面，其可行性和准确性尚未与标准经胸超声心动图（sTTE）检查结果进行充分比较。
方法与结果
目标人群包括125例未经过筛选的患者，这些患者均接受了sTTE和pTTE检查。测量了左心室（LV）舒张期和收缩期内径、缩短分数（FS）、室间隔（IVS）厚度、左心室后壁（PWT）厚度、左心房（LA）内径以及升主动脉直径。所有患者均完成了pTTE和sTTE的超声心动图测量（可行性为100%）。pTTE测得的LV内径、FS、IVS、PWT、LA内径和主动脉直径与sTTE显示出极好的相关性和一致性（r = 0.87 - 0.98，所有P < 0.001）。pTTE和sTTE在这些测量方面的观察者变异性相似。
结论
在本研究中，使用Acuson P10的pTTE在评估心腔大小和功能方面是可行且准确的。
