“…The TTEs were obtained and interpreted in accordance with the American Society of Echocardiography’s recommendations for a complete transthoracic echocardiographic examination. 25 TTEs included 2D, color Doppler, and pulsed and continuous wave Doppler imaging. Reports included qualitative and quantitative assessment of chamber dimensions, ventricular function, atrial size, LV wall thickness, aortic diameter, the severity of valvular lesions, and extracardiac findings.…”

Objective To assess the diagnostic capability of handheld echocardiography (HHE) compared with transthoracic echocardiography (TTE) performed and evaluated by experienced sonographers and expert echocardiographers. Patients and Methods We conducted a prospective study of adult outpatients undergoing comprehensive TTE from July 9, 2012, through April 3, 2013. Experienced sonographers performed a detailed, standardized examination with a handheld ultrasound device (Vscan; GE Healthcare) that included 2-dimensional and color Doppler images from standard imaging windows. TTE and HHE images were independently interpreted by expert echocardiographers to whom the other study was masked. Agreement between the standard TTE and the HHE reports was analyzed. Results The study group contained 190 patients (mean [SD] age, 62 [17] years; 49% male). κ Values were 0.52 for left ventricular (LV) enlargement, 0.52 for right ventricular enlargement, 0.62 for regional wall motion abnormalities, 0.73 for aortic stenosis, and 0.61 for mitral regurgitation. Lin concordance correlation coefficients ranged from 0.89 for LV end-systolic diameter to 0.78 for LV end-diastolic diameter. In 51 patients (27%), echocardiographic findings were discordant between HHE and standard TTE. The most common discordant finding was the presence vs absence of any regional wall motion abnormalities. In discordant cases, HHE tended to underestimate, rather than overestimate, the severity of abnormal findings. Conclusion HHE in experienced hands shows moderate correlation with standard TTE, but discordant findings were present in 27% of patients. HHE, even when performed and interpreted by experienced operators, should not be used as a surrogate for standard TTE.

“…All echocardiograms were performed in our Intersocietal Accreditation Commission in Echocardiography Laboratory in accordance with the American Society of Echocardiography (ASE) guidelines (12), and by the same sonographer to minimize technical variability. No patients in this study were noted to have atrial fibrillation/arrhythmias.…”

Objectives Scleroderma (SSc)-associated pulmonary arterial hypertension (PAH) is a major cause of mortality in SSc patients and represents an important diagnostic and therapeutic target. Our aims were to evaluate the relationship between echocardiogram-derived right heart hemodynamics and “gold standard” right heart catheterization (RHC) measurements in a scleroderma population, and investigate whether this relationship is modified by a subset of pulmonary hypertension. Methods We performed right heart catheterization and echocardiography on the same day, with pulmonary function testing in 21 consecutive subjects (age 57 ± 10, 81% female) with scleroderma and pre-capillary pulmonary hypertension. Results RHC measures including PA systolic and mean pressure, and pulmonary vascular resistance (PVR) correlated strongly with echo-derived data. RHC-derived pulmonary vascular resistance was negatively associated with RV systolic performance as measured by tricuspid annular plane systolic excursion (TAPSE, rho −0.70, p < 0.001), tissue Doppler tricuspid s’ velocity (rho −0.68, p 0.002), and RV fractional area change (rho −0.78, p < 0.001). Correlations with TAPSE and s’ velocity were strengthened when FVC%/DLCO% ≥ 1.6 used to identify pure PAH phenotypes in SSc. Bland-Altman analyses demonstrated strong agreement between RHC and echo-derived hemodynamic measures. Conclusions Our findings suggest that echocardiography may play a clinical role in identifying pulmonary hypertension and RV dysfunction non-invasively, particularly in a subset of SSc patients stratified by pulmonary function testing. This method may establish specific disease phenotypes with differential cardiovascular impact and prove useful as a marker of disease progression/risk stratification in SSC patients that warrants further investigation in larger cohorts.

N-terminal pro-B-type natriuretic peptide measurement is useful in predicting left ventricular hypertrophy regression after aortic valve replacement in patients with severe aortic stenosis

BackgroundThe predictive factors for early left ventricular hypertrophy (LVH) regression after aortic valve replacement (AVR) have not been fully elucidated. This study was conducted to investigate which preoperative parameters predict early LVH regression after AVR. Methods and results 87 consecutive patients who underwent AVR due to isolated severe aortic stenosis (AS) were analysed. Patients with ejection fraction <50% or concomitant coronary artery disease were excluded from the analysis. Preoperative evaluation including echocardiography and N-terminal pro-B-type natriuretic peptide (NT-proBNP) measurement was performed and midterm follow-up echocardiography was done at a median of 9 months after AVR. The presence of complete regression of LVH at the midterm follow-up was determined. In multivariate analysis, including preoperative echocardiographic parameters, only E/e 0 ratio was associated with midterm LVH regression (OR 1.11, 95% CI 1.01 to 1.22; p=0.035). When preoperative NT-proBNP was added to the analysis, logNT-proBNP was found to be the single significant predictor of midterm LVH regression (OR 2.00, 95% CI 1.08 to 3.71; p=0.028). By receiver operating characteristic curve analysis, a cut-off value of 440 pg/ mL for NT-proBNP yielded a sensitivity of 72% and a specificity of 77% for the prediction of LVH regression after AVR. Conclusions Preoperative NT-proBNP was an independent predictor for early LVH regression after AVR in patients with isolated severe AS.
