title: [Left auricular myxoma. Apropos of 9 cases. Study of echocardiographic and morphologic aspects. Familial inquiry].
abstract: A study was made of 9 cases of left atrial myxoma with emphasis on the echocardiographic, haemodynamic and anatomical aspects and on the main clinical features. An epidemiological enquiry was made regarding the possibility of recurrences or familial cases. It was negative, suggesting that such cases are rare. The echocardiographic signs of left atrial myxoma are inconstant. The mitral diastolic EF slope is variable, the delay in appearance of the tumour echo behind the mitral valve in diastole is not constant, and the atrial "a" wave may be preserved. The echocardiographic features are a function of the size and shape of the myxoma, as well as the length and site of implantation of its pedicle.
