OBJECTIVES To test the hypothesis that two populations of myocardial fibres-fibres aligned parallel to the surfaces of the wall and an additional population of fibres that extend obliquely through the wall-when working in concert produce a dualistic, self stabilising arrangement. METHODS Assessment of tensile forces in the walls of seven porcine hearts by(More)
The macroscopical structure of the ventricular myocardium has been an unsolved problem since the XVIth century, when Anatomy started as an authentic science. Since then the spatial organization of the myocardial fibres has represented, as Pettigrew says, "an arrangement so unusual and perplexing, that it has long been considered as forming a kind of Gordian(More)
Opinions are divided as to whether the rope-like secondary structure, which Torrent-Guasp dissected out of the myocardial body by the blunt unwinding technique (BUT) reveals some kind of functional compartmentation of the heart muscle. The myocardial fibres are aligned parallel to the fibre disruption (cleavage) plane, along which the band has been prepared(More)
OBJECTIVE To determine whether Raman microspectroscopy can identify different levels of oxidative sperm nDNA damage and to corroborate the findings using an established method and an alternative but complementary spectroscopic technique. DESIGN Three-way comparison of Raman profiles, Fourier transform infrared spectroscopy (FTIR) spectra, and(More)
The computation of the inclination angle of myocardial contractile pathways, based on the data from (1) optically and (2) manually digitized hearts is described. The measured raw data comprised: (1) A list epi of points on an "epicardial' surface S. (2) For each selected contractile pathway f, a list of points along the contractile pathway. For any point p(More)
BACKGROUND Because of the variation in the surgical procedures designed to reduce ventricular radius, along with differences in hospital care, it is difficult to disentangle the factors that may contribute to the success or failure of the partial left ventriculectomy. METHODS AND RESULTS We undertook partial left ventriculectomy in 18 patients, 10(More)
The architectural arrangement of the myocytes within the ventricular mass remains a highly contentious topic. It has recently been suggested by several distinguished surgeons that the overall myocardial structure is disposed in the form of a 'ventricular myocardial band'. There are, however, major anatomic deficiencies in this hypothesis, because the heart(More)
Die Batista-Operation ist eine neue therapeutische Option für Patienten mit terminaler Herzinsuffizienz aufgrund einer dilatativen Kardiomyopathie, die noch nicht sehr lange angewandt wird und einige Fragen aufgeworfen hat. Ein wesentlicher Aspekt dieses chirurgischen Eingriffs scheint die Art des Verschlusses der Ventrikulotomie zu sein, sodass wir über(More)
Concepts for ventricular function tend to assume that the majority of the myocardial cells are aligned with their long axes parallel to the epicardial ventricular surface. We aimed to validate the existence of aggregates of myocardial cells orientated with their long axis intruding obliquely between the ventricular epicardial and endocardial surfaces and to(More)
