BACKGROUND Respiratory dependence of tricuspid regurgitation (TR), a long-held concept suggested by murmur variation, remains unproven and of unclear mechanisms. METHODS AND RESULTS In 41 patients with mild or greater TR (median age, 67 years), we performed triple Doppler echocardiographic quantification (TR severity, right ventricular, and right atrial quantification) with simultaneous respi...

Background—Respiratory dependence of tricuspid regurgitation (TR), a long-held concept suggested by murmur variation, remains unproven and of unclear mechanisms. Methods and Results—In 41 patients with mild or greater TR (median age, 67 years), we performed triple Doppler echocardiographic quantification (TR severity, right ventricular, and right atrial quantification) with simultaneous respiro...

Evolución de la función sistólica ventricular derecha tras implante de válvula aórtica percutánea con ecocardiografı´a speckle tracking bidimensional To the Editor, In recent years, left ventricular function has been shown to improve in patients with severe aortic stenosis treated with transcatheter aortic valve implantation (TAVI), 1 and a reduction of left ventricular hypertrophy has also bee...

OBJECTIVE We sought to evaluate the vena contracta width (VCW) measured using color Doppler as an index of severity of tricuspid regurgitation (TR). BACKGROUND The VCW is a reliable measure of mitral and aortic regurgitation, but its value in measuring TR is uncertain. METHODS In 71 consecutive patients with TR, the VCW was prospectively measured using color Doppler and compared with the re...

The application of the Alfieri technique in humans is a well-known and pioneering thechnique that was replaced by modern atrioventricular valve repair strategies.1,2 This canines also yet valid alternative, particullary to canine tricuspid dysplasia.1 “strategy” consists transform “monorificial” dysplastic insufficiency into “biorificial” one means suturing at level apposition face site greates...

Different patterns of left-ventricular (LV) diastolic dysfunction were reported in patients with pulmonary hypertension (PHT). There are no data regarding the relationship between the severity of PHT and LV diastolic dysfunction. In order to determine the severity of PHT at which LV diastolic dysfunction occurs and to identify its pattern, we studied by Doppler echocardiography 120 patients wit...

Abnormal diffusing capacity is common in HIV-infected individuals, including never smokers. Aetiologies for diffusing capacity impairment in HIV are not understood, particularly in those without a history of cigarette smoking. Our study was a cross-sectional analysis of 158 HIV-infected individuals without acute respiratory symptoms or infection with the aim to determine associations between a ...

OBJECTIVES To examine the relationship between chronic bacterial infection and pulmonary hypertension, using Doppler echocardiography, in patients with cystic fibrosis (CF). METHODS A prospective cross-sectional study involving CF patients (>16 years of age) admitted to a program for adults with the disease. The study included 40 patients with a mean age of 23.7 +/- 6.3 years. Patients were s...
