Left Ventricle of the Transplanted Human Heart
The present study was designed to investigate the anisotropy of systolic chord shortening hi the lateral, inferior, septal, and anterior regions of the human left ventricle. At the time of surgery, 12 miniature radiopaque markers were implanted into the left ventricular midwall of the donor heart in 15 cardiac transplant recipients. Postoperative biplane cineradiograms were computeranalyzed to ...
متن کاملDynamics in the Transplanted Human Heart
To quantify the three-dimensional regional dynamics of the left ventricular (LV) midwall and the centroid and cross-sectional shape of the LV chamber in the transplanted human heart, 12 miniature radiopaque tantalum markers were implanted in the LV midwall of the donor heart at the time of cardiac transplantation in 15 patients. Stereo cineradiography in the late postoperative period (mean, 52 ...
متن کاملElectrophysiological abnormalities in the transplanted human heart.
Fourteen relatively long term survivors of cardiac transplantation underwent systematic electrophysiological evaluation and ambulatory electrocardiographic monitoring. Six patients had prolonged conduction intervals during sinus rhythm. Sinus node function could be assessed in all donor atria and in 10 recipient atria. Sinus node recovery times were prolonged in four of the donor atria and in s...
متن کاملThe surgically denervated, transplanted human heart.
In this issue of Circulation, Regitz et all provide evidence that the transplanted human heart remains denervated for as long as 5 years after transplantation. These authors measured myocardial catecholamines in right ventricular septal endomyocardial biopsies taken from 24 orthotopically transplanted hearts and found measurable norepinephrine levels in only two samples, both of which were from...
متن کاملThe electrophysiologic effects of quinidine in the transplanted human heart.
Using His bundle recording techniques, we examined direct and autonomically mediated conduction system effects of quinidine in five cardiac transplant recipients who have anatomically denervated hearts. We made control conduction interval and refractory period measurements, and then infused 10 mg/kg quinidine gluconate over a 20-min period. At 30 min, we determined the electrophysiologic change...
