An echocardiogram performed on a 72-year–old man with exertional dyspnea revealed asymmetrical septal hypertrophy (maximum thickness, 1.8 mm) and turbulent flow in the left ventricular outflow tract (LVOT; Movie I in the onlineonly Data Supplement) with a resting gradient of 62 mm Hg and a peak provoked gradient of 166 mm Hg after Valsalva maneuver (Figure, A and B), consistent with hypertrophi...
Conspicuous left axis deviation was found in two thirds (27 patients) of 44 children with a perimembranous ventricular septal defect, echocardiographic signs of apposition of the septal tricuspid valve leaflet, and an aneurysm of the membranous septum. In 10 patients earlier electrocardiograms did not show left axis deviation; this feature appeared when the aneurysm of the membranous septum was...
the most frequent congenital heart defects in the neonatal period are ventricular septal defects. ventricular septal aneurysms can rarely develop from an interventricular septal (ivs) defect in adults. we describe a 47-year-old man with an aneurysm in the ivs growing towards the right ventricle, which was confirmed by cardiac computed tomographic angiography and was missed by echocardiography.
The M-mode echocardiogram can be obtained in the developing human fetus from around the 16th week of gestation until term. Errors in interpretation of the M-mode echocardiogram can be avoided by concurrent two dimensional fetal cardiac examination. The pattern of motion of the mitral, tricuspid, aortic, and pulmonary valves and ventricular wall motion can be studied. Motion of the foramen ovale...
vexity that is determined by a left-to-right positive transseptal pressure gradient, and this shape is maintained during the cardiac cycle (1, 2). Changes in the position and geometry of the ventricular septum occur when there is an acute or chronic imbalance between the left and right ventricular loading conditions, such as a postoperative state of tetralogy of Fallot, an atrial septal defect,...
BACKGROUND Using data from 4 community-based cohorts of African Americans, we tested the association between genome-wide markers (single-nucleotide polymorphisms) and cardiac phenotypes in the Candidate-gene Association Resource study. METHODS AND RESULTS Among 6765 African Americans, we related age, sex, height, and weight-adjusted residuals for 9 cardiac phenotypes (assessed by echocardiogr...
BACKGROUND There has been limited data addressing outcomes of extensive septal myectomy in Chinese patients with hypertrophic obstructive cardiomyopathy (HOCM). In this study, the objective was to evaluate the clinical and echocardiographic outcomes of extensive septal myectomy in a relative large number of Chinese HOCM patients over long-term follow-up. METHODS We retrospectively studied 139...
Left ventricular and left atrial volume, left ventricular ejection fraction, and left ventricular muscle mass were determined preoperatively and postoperatively in 13 patients who underwent surgical closure of ventricular septal defects in the first two years of life. Left ventricular end-diastolic volume and systolic output averaged 255 +/- 19% (+/- SEM) and 240 +/- 19% of normal, respectively...
In nine conscious, chronically instrumented dogs, ultrasonic dimension transducers measured left ventricular anterior-posterior and septal-free wall minor axis and major axis diameters. Matched micromanometers measured right and left ventricular transmural and transeptal pressures. Ventricular pressures and volumes were varied by inflation of implanted vena caval and pulmonary artery occluders,...
BACKGROUND We examined the relationship between glucose homeostasis and comprehensive measures of cardiac structure and function among a representative sample of US Hispanics. METHODS AND RESULTS ECHO-SOL (Echocardiographic Study of Latinos), an echocardiographic ancillary study of the HCHS/SOL (Hispanic Community Health Study/Study of Latinos), enrolled 1818 Hispanic/Latino men (43%) and wom...
