TLDR
The results support the hypothesis that phasic changes in left atrial dimension are largely responsible for the echocardiographically observed movement of the aortic root and indicate a potential role for eChocardiography in the analysis ofleft atrial events.Abstract:
The echocardiographically recorded movement of the aortic root was studied by analysing the relation between posterior aortic wall motion and other intracardiac events. The systolic anterior movement of the aortic root continued beyond aortic valve closure and in cases with mitral regurgitation began significantly earlier than in normal subjects. The diastolic rapid posterior movement began after mitral valve opening but did not occur in patients with mitral stenosis. The total amplitude of aortic root motion was increased in patients with mitral regurgitation, diminished in cases of mitral stenosis, and was normal with aortic regurgitation. In patients with atrioventricular block an abrupt posterior movement followed the P wave of the electrocardiogram irrespective of its timing in diastole. These observations correlate with the expected changes in left atrial volume during the cardiac cycle both in the normal subjects and patients with heart disease. The results support the hypothesis that phasic changes in left atrial dimension are largely responsible for the echocardiographically observed movement of the aortic root and indicate a potential role for echocardiography in the analysis of left atrial events.read more

Echocardiographic diastolic ventricular abnormality in hypertensive heart disease: atrial emptying index.

TL;DR: The atrial emptying index appears to be an early indicator of abnormalities of left ventricular diastolic compliance in uncomplicated hypertension, even before electrocardiographic or systolic echocardiographic abnormalities are detectable.

Role of M-mode technique in today's echocardiography.
TL;DR: In certain situations, M-mode recordings of the valves and interventricular septum can be particularly helpful in making a more accurate and complete echocardiographic cardiac assessment, thus helping to make the examination more cost-effective.
Journal ArticleDOI
An echocardiographic assessment of atrial mechanical behaviour.
TL;DR: Relations between movement of the atrioventricular ring and changes in left atrial and ventricular dimensions were studied by echocardiography and compared with apexcardiography and Doppler mitral flow velocity traces in healthy controls and patients with left ventricular hypertrophy.

TL;DR: The results indicate that LV contractile performance plays an important role in determining LA passive filling during ventricular systole, and that the LAPFR was strongly affected by the degree of LVPER.

TL;DR: The PAW-OV-Ex seems to mirror the abnormalities in volume changes of the left side of the heart resulting from pulmonary embolism, while the RVEDD/LVEDD ratio was increased and the mitral valve E-F slope and left atrial dimension changed variably.

Echocardiography of the aortic root.
Raymond Gramiak,Pravin M. Shah +1 more
TL;DR: The echo pattern of the aortic root is elicited by locating the typical echo of the mitral valve and then angulating the transducer medially and sometimes cephalically.

TL;DR: By obtaining a true internal dimension of the left atrium rather than merely visualizing one or two of the chamber's external borders, this procedure is more accurate than routine cardiac fluoroscopy and chest roentgenograms.

Myocardial Function and Left Ventricular Volumes in Acquired Valvular Insufficiency
TL;DR: The effect of valvular insufficiency on left ventricular volumes was studied by an angiographic method in 37 patients and results show good agreement with subsequent surgical findings in the 15 patients who underwent operation.

Echocardiography of the normal and diseased aortic valve.
Raymond Gramiak,Pravin M. Shah +1 more
TL;DR: Echocardiography studies of the normal aortic valve and the valve involved by disease were accomplished with pulsed ultrasonic techniques and extended recording by oscilloscope record camera, finding a good correlation existed between this abnormal echo pattern and radiological, surgical, or pathological evidence of valve cusp calcification.

Diagnosis of Aortic Root Dissection by Echocardiography
TL;DR: Six patients with aortic root dissection confirmed by angiography, surgery, or autopsy were studied by echocardiography and demonstration of enlargement of the aorti root with marked parallel widening of anterior and/or posterior walls appears to be specific for aortsic root involvement in dissecting aneurysm of theAorta.
