Physiological and hemodynamic evaluation of nonuniform direct cardiac compression.
BACKGROUND Biventricular direct cardiac compression (DCC) has the potential to support the failing heart without the complications associated with a blood/device interface encountered with the use of current ventricular assist devices. A clinically designed DCC device that provides compression pressure around the base of the heart in synchrony with native ventricular contractions was evaluated ...
متن کاملThe Frank--Starling curve.
A basic property of the normal heart is that if its volume is increased, there is an increase in the strength of the contraction. The phenomenon is known as Starling's Law, and as the FrankStarling mechanism. This phenomenon is of great importance. If the heart were unable to increase its output when distended, the distension would become progressively severe. The underlying important relation ...
متن کاملLeft Ventricular Pressure-Volume and Frank-Starling Relations in Endurance Athletes
Background. Endurance athletes have a high incidence of orthostatic intolerance. We hypothesized that this is related to an abnormally large decrease in left ventricular enddiastolic volume (LVEDV) and stroke volume (SV) for any given decrease in filling pressure. Methods and Results. We measured pulmonary capillary wedge (PCW) pressure (Swan-Ganz catheter), LVEDV (two-dimensional echocardiogra...
متن کاملFrank-Starling mechanism and short-term adjustment of cardiac flow.
The Frank-Starling law of the heart is a filling-force mechanism (FFm), a positive relationship between the distension of a ventricular chamber and its force of ejection, and such a mechanism is found across all the studied vertebrate lineages. The functioning of the cardiovascular system is usually described by means of the cardiac and vascular functions, the former related to the contractilit...
متن کاملcardiac damage in left breast cancer patients
Introduction :Today there is general awareness of the potential damage to the heart in left- sided (more than in rightsided) breast cancer radiotherapy. Material & Method: Historical changes in tumor and heart doses are presented here along with the impact of different RT techniques and volumes. Results: Individual and pharm...
