“…The magnitude and velocity-time integral of the PV s waves reflect LA reservoir function and are determined by LV systolic function and LA relaxation (PV s1 ), LA compliance (PV s1 and PV s2 ), and right ventricular stroke volume (PV s2 ) (33). Peak velocity and velocity-time integral of PV d is an index of LA conduit function (35) and is dependent on factors that influence LA afterload: LV relaxation and early filling (12) and mechanical obstruction from the mitral valve apparatus (36). During LA contraction, blood is ejected from the LA into the LV and the pulmonary veins.…”

Left atrial (LA) enlargement has been proposed as a barometer of diastolic burden and a predictor of common cardiovascular outcomes such as atrial fibrillation, stroke, congestive heart failure, and cardiovascular death. It has been shown that advancing age alone does not independently contribute to LA enlargement, and the impact of gender on LA volume can largely be accounted for by the differences in body surface area between men and women. Therefore, enlargement of the left atrium reflects remodeling associated with pathophysiologic processes. In this review, we discuss the normal size and phasic function of the left atrium. Further, we outline the clinically important aspects and pitfalls of evaluating LA size, and the methods for assessing LA function using echocardiography. Finally, we review the determinants of LA size and remodeling, and we describe the evidence regarding the prognostic value of LA size. The use of LA volume for risk stratification is an evolving science. More data are required with respect to the natural history of LA remodeling in disease, the degree of LA modifiability with therapy, and whether regression of LA size translates into improved cardiovascular outcomes.

“…Such factors as left atrial relaxation [9], displacement of the mitral annulus during systole [1,6], preload condi tions [4,7,8], mitral regurgitation [12][13][14] and left atrial pressure [10,14,15] have been reported to regulate the systolic peak flow velocity of the PVF. In the present study, the peak systolic flow velocity in the patients with mitral stenosis was found to be decreased, and correlated significantly with the systolic amplitudes of the mitral annular motion and of the interatrial septal motion, and also with the left atrial dimension.…”

“…In particular, the pulmonary venous flow velocity pattern (PVF) can be recorded more easily by this method than by transthorac ic echocardiography. Analysis of the PVF with the trans mitral flow velocity pattern has enabled us to evaluate cardiac function in many cardiac diseases [1][2][3][4][5][6][7][8][9][10]. In the present study we recorded the PVF in patients with mitral stenosis and attempted to elucidate the hemodynamic relationship between the left atrium and left ventricle in this abnormality.…”

For evaluation of pulmonary venous flow (PVF) in mitral stenosis, transthoracic and transesophageal echocardiography were performed in 33 patients with mitral stenosis and 20 normal controls. The peak systolic flow velocity of the PVF was significantly lower in patients with mitral stenosis and atrial fibrillation. The peak diastolic flow velocity of the PVF was significantly lower in the patients with mitral stenosis than in normal controls. The diastolic wave recorded as laminar flow in the mitral stenosis group showed a peak in the rapid filling phase with a gradually descending slope of velocity during mid to late diastole. There was a significant negative correlation between the peak diastolic flow velocity of the PVF and the pressure half time from transmitral flow obtained by continuous wave Doppler in the mitral stenosis group. These results demonstrate that evaluation of the PVF is helpful in understanding hemodynamic events between the left atrium and left ventricle in patients with mitral stenosis.

“…Those patterns of pulmonary venous blood flow changes are related with LA dysfunction, mainly in atrial relaxation, compliance, and reservoir function 15). Assessment of pulmonary venous blood flow variables and patterns by Doppler echocardiography seems useful in the management of AF patients 16).…”

BackgroundAtrial fibrillation (AF) is the most common cardiac arrhythmia with a population prevalence of about 1%. Natriuretic peptide level is elevated in patients with AF with diastolic dysfunction even with a normal left ventricular (LV) ejection fraction. The N-terminal pro-brain natriuretic peptide (NT-proBNP) level and Doppler echocardiographic parameters for diastolic function have shown correlation with LV filling pressures. We aimed to evaluate the relationship between echocardiographic parameters and serum NT-proBNP in patients with AF with preserved LV ejection fraction.MethodsWe examined transthoracic echocardiography and NT-proBNP levels in the patients with AF and patients with sinus rhythm. Blood samples were taken for serum NT-proBNP measurements within 24 hours of echocardiographic examination. The group 1 was the patients with sinus rhythm (n = 30, mean age 68 ± 13 years) and the group 2 was the patients with AF (n = 33, mean age 70 ± 14 years).ResultsThe group 2 patients had significantly higher mitral E, E' (lateral annulus), E/E' (septal annulus), left atrial (LA) volume index, LA size, pulmonary vein diastolic velocity, and NT-proBNP level than those of group 1 patients (p < 0.05). The area under the receiver-operating characteristic curve showed a NT-proBNP had good diagnostic power for E/E' (septal annulus) > 15 in patients with AF at cutoff value of 433 pg/mL.ConclusionNT-proBNP level is well correlated with Doppler echocardiographic parameters of diastolic function in patients with AF and preserved LV ejection fraction. NT-proBNP level more than 433 pg/mL may suggest elevated LV filling pressure in patients with AF.
