Coronary artery disease has emerged as the leading cause of late morbidity and mortality in heart transplant recipients. The incidence of allograft coronary artery disease has been reported to be as high as 40% to 50% by 5 years. Coronary angiography remains the standard approach for surveillance of coronary artery disease in this patient population.(More)
New rules for quality assurance provoked a comparison of effects of two approaches used concurrently for 14 years. In an incidental approach, a multidisciplinary conference reviewed all postoperative complications as they occurred and attributed each to one of six causes. Remedies were instituted and data were filed. In a statistical approach, death and(More)
Hypothyroidism is associated with profound left ventricular dysfunction. Brain-dead organ donors and patients undergoing cardiopulmonary bypass are chemically hypothyroid with significantly reduced circulating free triiodothyronine (T3). To test the hypothesis that T3 enhances left ventricular function in a hormonally deficient environment, a total of 36(More)
The incidence of acute myocardial infarction (AMI) complicating coronary artery bypass grafting (CABG) has previously been based on concordance of electrocardiographic, enzymatic and scintigraphic criteria. Technetium-99m pyrophosphate (Tc-PPi) single-photon emission computed tomography now enables detection of AMI with high sensitivity and specificity.(More)
We used a sonomicrometric determination of ventricular dimension to examine the effect of ischemia and reperfusion on the work-length relationship in the intact heart to develop a useful and precise variable of ventricular contractile response to injury. Twenty anesthetized dogs were instrumented with epicardial ultrasonic dimension transducers to record(More)
Hypothyroidism is associated with an abnormal hemodynamic state characterized by decreased heart rate, stroke volume, output, and contractility, and increased systemic vascular resistance. Since cardiopulmonary bypass (CPB) and surgical stress can induce profound decreases in triiodothyronine (T3) levels, the hemodynamic consequences of "stress-induced"(More)
Endomyocardial biopsy remains the primary method for diagnosis of cardiac allograft rejection. Generally, endomyocardial biopsy is considered a relatively safe procedure in heart transplant recipients. Complications that have been reported are related to catheter insertion and include carotid arterial puncture, prolonged bleeding, vasovagal reaction,(More)
Cardiac storage for transplantation is currently limited to 6 hours. To better understand the metabolic changes that occur during hypothermic (4 degrees C) storage, we monitored the morphologic and metabolic changes in the canine myocardium at 0, 12, and 24 hours of storage in University of Wisconsin solution. Attempts to isolate cardiac mitochondria(More)
Cardiopulmonary bypass causes a "euthyroid-sick" state characterized by low levels of circulating triiodothyronine. Triiodothyronine supplementation in this setting has been postulated to improve postischemic left ventricular function by increasing the availability of myocardial high-energy phosphates. These postulates have not been substantiated, however,(More)
BACKGROUND Cardiac transplantation is an accepted treatment modality for end-stage heart failure. Coronary artery disease remains a major cause of mortality in the long term after heart transplantation. Despite the high prevalence of coronary artery disease in heart transplant recipients, currently used noninvasive tests as well as invasive tests are highly(More)
