The effect of valve orientation on flow development in a model human aorta was studied by means of a qualitative flow visualization technique. The model replicated the geometry of the human aorta and the experiment simulated a physiologically realist

In vitro fluid dynamic characteristics of aortic valve prostheses were experimentally measured for physiological relevant pulsatile flows using hot-film velocimetry. The prostheses studied were (i) centrally occluding ball-in-cage and (ii) tilting di

The anatomy of the coronary circulation was correlated with left ventricular segmental contractile motion in 162 patients: 43 with normal coronary arteriograms, 119 with significant (> 75%) obstruction of the right coronary artery and/or left anterio

Temporal variation in perfusion to small segments of the myocardium was studied in 19 opened-chest dogs. In six control dogs, three or four differently labeled 7-10 mu microspheres were injected simultaneously into the left atrium to assess the varia

Total, phasic, and regional flow were studied in 12 open-chest dogs with aortic regurgitation. An adjustable catheter device was used to produce aortic regurgitation. Four differently labeled 7 to 9μ microspheres were injected into the left atrium d

In nine anesthetized dogs, recordings of the first derivative of the transthoracic impedance cardiogram (ICG) were made during varying grades of acute aortic regurgitation. Acute aortic regurgitation was induced using a specially designed umbrella ca

A mathematical model is presented describing the time- and length-dependent behavior of cardiac muscle. The model describes a wider variety of experimental data than do previously published models. It incorporates a modification of the Hill equation

In brief: Blood measurements were taken in 23 marathon runners to investigate whether the hardness of the sole of the running shoe would affect RBC indexes. Runners were randomly assigned to a group with either a firm-sole running shoe or an air-cush

A conical hot film anemometer probe was used to measure instantaneous velocities in the ascending aorta of anaesthetised, open-chest dogs. The probe was mounted on a saddle which allowed traversal of the aorta in 1 mm increments 4 cm above the aortic

Mitral valve motion, left ventricular segmental contraction and severity of arterial stenosis were analyzed in 92 patients with coronary artery disease and 28 patients with "atypical chest pain" and normal coronary arterio-rams. Mitral valve motion w
