Early transmitral flow (MiF) patterns depend strongly on the rate of fall of measured left ventricular pressure (Pm) determined by both the active decay of pressure (Pa) due to myocardial relaxation and the increase in pressure due to stretch of passive elements during filling (Pp). This study was designed to uncouple passive forces from deactivation in order to reveal the instantaneous rate an...

Two pathological specimens are presented in which the morphological left ventricle contains the right atrioventricular ostium, completely or in its major portion and, totally, the left atrioventricular ostium. It is suggested from a consideration of these cases and of the pathological material available in the literature that this constitutes an entity that can be usefully separated from the he...

A case, the sixth, ofdouble outlet left ventricle is reported, the diagnosis being made by cardiac catheterization and angiocardiography. Though the existence of such a malformation has been questioned on embryologicalgrounds, double outlet left ventricle must now be regarded as a recognized cardiac anomaly. The embryological significance of this case is discussed and it is suggested that the m...

Left ventricular free wall rupture is a dramatic but not always fatal complication from myocardial acute infarction. However, if proper diagnosis is delayed, surgical treatment may be compromised. The authors report a case of large pseudoaneurysm in left ventricular inferior wall diagnosed on angiography study.

OBJECTIVE To establish the incidence of systolic and diastolic dysfunction of the right and left ventricle in a large cohort of patients after Mustard or Senning operations and to assess changes in the incidence on long term follow up. DESIGN Postoperative case-control study using radionuclide ventriculography. Ejection fractions, peak filling rates, rapid filling periods and fractions, slow ...

introduction: nicotinamide adenine dinucleotide phosphate (nadph) oxidase-2 (nox2) is one of the predominant sources of ros production during myocardial ischemia-reperfusion and can be induced by angiotensin ii. the evidence suggests that pharmacological blockers of renin-angiotensin system can exert direct tissue effects independent of their ability to regulate blood pressure. the mechanism(s)...

the present study attempted to compare the structural and functional changes of left heart ventricle in female basketball players of khuzestan superior league (aged between 18 and 29) during regular training and long-term detraining. out of 30 female players, 15 subjects were assigned randomly to regular training group and 15 subjects to long-term detraining group. the structural and functional...
