Left ventricular chamber geometry in cardiomyopathies: insights from a computerized anatomical study

Normalized diastolic properties after left ventricular assist result from reverse remodeling of chamber geometry.

BACKGROUND Normalization of diastolic properties after left ventricular (LV) assist may result from a change in myocardial material properties, chamber size, or both. This study tested the hypothesis that reported normalization of LV diastolic properties is primarily due to remodeling of chamber geometry. METHODS AND RESULTS Hearts were obtained at transplantation from 8 patients with dilated...

Echocardiographic Evaluation of left Ventricular Function and Geometry in Pediatric Patients with Kidney Transplantation

Extended abstract Echocardiographic Evaluation of Left Ventricular Function and Geometry in Pediatric Patients with Kidney Transplantation Cardiovascular disease (CVD) is an important, leading cause of mortality and morbidity in patients with chronic kidney disease (CKD) as well as in renal transplant recipients. Cardiovascular complications become more important in children because of the i...

Left ventricular bands. A normal anatomical feature.

Discrete delicate fibromuscular structures crossing the cavity of the left ventricle were identified on morphological examination in 329 (48%) of 686 hearts from patients of all ages with congenital heart disease, acquired heart disease, or normal hearts. These structures were also present in 151 (95%) of 159 hearts from animals of six species. Cross sectional echocardiographic findings compati...

Impact of Chamber Dilatation on the Prognostic Value of Left Ventricular Geometry in Hypertension

BACKGROUND The different geometric patterns of the left ventricle may or may not coexist with chamber dilatation. The prognostic impact of such a combination is unclear. METHODS AND RESULTS We studied a cohort of 2635 initially untreated patients with hypertension, mean age 50 years. At entry, 24-hour ambulatory blood pressure progressively increased across the patterns of normal geometry, co...
