“…Although TR jet maximum velocities were similar in two groups, RAP TTE and delta RAP were significantly higher in group 2. 19 New echocardiographic formulas using these parameters and other possible parameters should be created and tested in further studies. 3,12,13 However, the association between the RAP overestimation and severe TR was not analyzed in those studies.…”

“…Several studies have documented the ability of echocardiographic parameters to assess mean RAP in patients with various cardiac disorders. 11,12,[15][16][17][18] Inspection of the IVC with measurement of the diameter and the effect of breathing or sniffing (collapsibility) is the method that is most thoroughly studied, 11,12,[15][16][17] and has gained the most widespread use. In this study, we found a high degree of concordance between right-and left-sided filling pressures in HTx recipients.…”

Diastolic dysfunction is a recognized complication in heart transplant (HTx) recipients that limits exercise capacity and is a risk factor for mortality. We investigated the ability of echocardiography to detect elevated pulmonary capillary wedge pressure (mean PCWP>15 mmHg) in HTx recipients. This retrospective study comprised HTx recipients with echocardiography and right heart catheterization within 24 hours (n = 100, 113 investigations). Echocardiographic assessment was performed using mitral inflow (E/A ratio, deceleration time [DT], isovolumic relaxation time [IVRT]), tissue Doppler (E/E' lateral) parameters, and the Doppler-estimated pulmonary artery systolic pressure (Doppler PASP). The right atrial pressure (RAP) was estimated based on size and the effect of respiration or sniffing on the inferior vena cava diameter. Cutoff values were determined from a derivation group (n = 57, receiver operator characteristic curve analysis) and evaluated in a test group (n = 56). Elevated PCWP were found in 38%. The RAP and PCWP were both normal in 58 investigations and elevated in 39 investigations (concordance rate of 86.6%). The presence of signs of increased RAP by echocardiography or with three of five parameters (E/A, DT, IVRT, E/E' lateral, and Doppler PASP) reaching the cutoff values ruled in elevated PCWP with positive likelihood ratios ranging from 15.3 to 9. With normal RAP by echocardiography or none of the other parameters reaching cutoff values elevated PCWP can be ruled out with negative likelihood ratios ranging from 0.07 to 0.19. In conclusion, elevated PCWP in HTx recipients can be assessed using echocardiography.

2; P<0.001) and right atrial volume index (15.66±3.09 versus 20.47±4.82 mL/m 2 ; P<0.001) significantly increased after training in female athletes. Left atrial global peak atrial longitudinal strain and peak atrial contraction strain significantly decreased after training in female athletes (43.9±9.5% versus 39.8±6.5%; P<0.05 and 15.5±4.0% versus 13.9±4.0%; P<0.05, respectively). Right atrial peak atrial longitudinal strain and peak atrial contraction strain showed a similar, although non-significant decrease (42.8±10.6% versus 39.3±8.3%; 15.6±5.6% versus 13.1±6.1%, respectively). Neither biventricular E/e′ ratio nor biatrial stiffness changed after training, suggesting that biatrial remodeling occurs in a model of volume rather than pressure overload. Conclusions-Exercise is able to induce biatrial morphological and functional changes in female athletes. Biatrial enlargement, with normal filling pressures and low atrial stiffness, is a typical feature of the heart of female athletes. These findings should be interpreted as physiological adaptations to exercise and should be considered in the differential diagnosis with cardiomyopathies. (Circ Cardiovasc Imaging. 2014;7:222-229.)
