Analog Simulation of Left Ventricular Bypass Mode Control

Left ventricular function following coronary bypass surgery.

The effect of coronary artery bypass grafts on left ventricular performance was evaluated by analyzing preoperative (preop) and postoperative (postop) biplane left ventriculograms of 37 patients who were restudied at a mean of 13 months after operation. Eighty-two percent of the grafts were patent. Segmental wall shortening and segmental shortening velocities (mea Vcf) in the anterior, inferior...

early outcome of coronary artery bypass grafting in patients with severe left ventricular dysfunction

background: left ventricular dysfunction is one of the most powerful predictors of early and late outcomes in patients who undergo coronary artery bypass grafting (cabg). the aim of this study was to assess the early results of cabg that predict 30-day mortality and prolonged length of hospital stay (los) after cabg in patients with an ejection fraction (ef) of 30% or less. methods: seven hundr...

Arrhythmias in two patients with left ventricular bypass transplants.

Two patients who underwent left ventricular bypass transplants are described. Both patients sustained postoperative rhythm disturbances of their own hearts during sinus rhythm of the donor hearts. Illustrative examples of atrial flutter, ventricular flutter, ventricular fibrillation, blocked atrial extrasystoles, and double ventricular parasystole in the recipient hearts are presented. The pati...

Left ventricular free wall rupture after coronary artery bypass grafting.

Giant left ventricular pseudoaneurysm following coronary artery bypass graft surgery.

Figure 2: Late-enhancement T1-weighted (a) and T2-weighted (b) magnetic resonance images confirmed the presence of the pseudoaneurysm (p) with the enhancement of the surrounding thickened pericardial layers (arrowheads) and revealed a trans-mural haemorrhagic inferior myocardial infarction (arrow in a); T2-weighted images demonstrated the presence of oedema in adjacent myocardium (arrow in b), ...
