1. Avaliação morfogeométrica do ventrículo esquerdo e do anel valvar mitral na cardiomiopatia dilatada isquêmica ou idiopática: estudo comparativo computadorizado / Morphogeometric evaluation of left cardiac ventricle and mitral valval ring in dilated ischemic and idiopathic cardiomyopathies: computer assisted comparative study
INTRODUÇÃO: O conhecimento anatômico desempenha importante papel no desenvolvimento de técnicas diagnósticas e cirúrgicas. Com esse objetivo, na área cardiológica, se mostra fundamental para o entendimento do processo de remodelamento cardíaco que acompanha as cardiomiopatias dilatadas (CMD) tanto isquêmicas (CMDIsq) como idiopáticas (CMDId), de m

2. Proportion between the segments of the tricuspid valve annulus: anatomic study with human hearts / Determinação da proporção entre os segmentos do anel da valva tricuspide : estudo anatomico em corações de humanos
Objective: The purpose of this study was to determine the proportion among the segments of the human tricuspid valve annulus. Methods: Descriptive autopsy study of 30 human hearts, without fixation, with less than six hours of post-mortem period, without congenital or acquired lesions and without tricuspid regurgitation. The tricuspid valve insufficiency was

3. Anatomy of the left atrioventricular complex of the Minke whale (Balaenoptera acutorostrata Lacépède, 1804) / Anatomia do Complexo Valvar Atrioventricular Cardíaco Esquerdo da Baleia Minke (Balaenoptera acutorostrata Lacépède, 1804)
A few information exist in the literature relative to the morphology of the circulatory organs of the whale, especially concerning the valvar complex of the heart. It tried to approach in this work, the macroscopic anatomy of the left atrioventricular valve of the whale Minke, as well as the musculi papillaris and Chordae tendineae. It was studied the anatom

4. Ventricular Endoaneurysmorrhaphy: Results of an Improved Method of Repair
We recently repaired 4 large ventricular aneurysms using a new technique that restores normal shape, contour, and volume to the ventricle. An elliptical woven Dacron patch graft is fashioned to replace the diseased area in the ventricular cavity, and to exclude the nonfunctioning fibrous area. In all patients, left ventricular function improved postoperative

5. Dextrocardia--value of segmental analysis in its categorisation.
Dextrocardia can be defined as a heart in the right chest with the major axis to the right. This definition, however, conveys no information regarding the chamber arrangements and internal anatomy of the heart. Of 40 patients satisfying this definition in the files of the Brompton Hospital, 33 had angiocardiographic data adequate for complete analysis in ter

6. Left juxtaposition of the auricles with l-position of the aorta. Report of 6 cases.
Six hearts are described in which juxtaposition of the auricles to the left of the great arteries (left juxtaposition) was associated with l-postion of the aorta. Atrial anatomy was abnormal but constant; the os of the right auricle occupied the expected site of the atrial septum, producing posterior and inferior desplacement of this structure. This is of im

7. Magnetic resonance imaging planes for the 3-dimensional characterisation of human coronary arteries.
We report a magnetic resonance imaging study which developed a consistent hierarchy of imaging planes for examination of the origins, courses and principal branches of the main coronary arteries of prepared human cadaveric hearts. The reference longitudinal axis was chosen between the aortic valve and the apex of the left ventricle. A series of transverse pl

8. Anatomical and echocardiographic correlates of normal cardiac morphology in the late first trimester fetus.
OBJECTIVES: To describe the normal cardiac morphology as seen by transvaginal ultrasound imaging in the first trimester fetus and to compare it with the morphology of the heart as seen by microdissection at the same gestational age. DESIGN: In 53 mothers undergoing early sonography, the fetal heart was examined and the images recorded. The gestational age ra

9. Dual role for neural crest cells during outflow tract septation in the neural crest-deficient mutant Splotch2H
Splotch2H (Sp2H) is a well-recognized mouse model of neural crest cell (NCC) deficiency that develops a spectrum of cardiac outflow tract malformations including common arterial trunk, double outlet right ventricle, ventricular septal defects and pharyngeal arch artery patterning defects, as well as defects in other neural-crest derived organ systems. These

10. Doubly committed subarterial ventricular septal defect: new morphological criteria with echocardiographic and angiocardiographic correlation.
To gain a better understanding of the anatomy of doubly committed subarterial defects and its relation to findings at cross sectional echocardiography and angiocardiography, eight necropsy specimens from patients with this condition were examined, and preoperative echocardiograms and angiocardiograms from 313 patients with surgically or necropsy confirmed ou

11. Asymmetry of cardiac [123I] meta-iodobenzyl-guanidine scans in patients with ventricular tachycardia and a "clinically normal" heart.
OBJECTIVE--Patients with exercise induced ventricular tachycardia associated with a "clinically normal" heart may have an abnormality of the regional distribution of the cardiac sympathetic nerve supply. In this study the regional distribution of the myocardial nerve supply in patients with ventricular tachycardia (VT) and control subjects was examined by [1
