BACKGROUND Optimal criteria for valve replacement are unclear in asymptomatic/minimally symptomatic patients with aortic regurgitation (AR) and normal left ventricular (LV) performance at rest. Moreover, previous studies have not assessed the prognostic capacity of load-adjusted LV performance ("contractility") variables, which may be fundamentally related(More)
Twenty-two late survivors of Mustard repair of transposition of the great arteries underwent treadmill exercise testing to assess exercise endurance, and radionuclide cineangiography to measure rest and exercise right ventricular (RV) and left ventricular (LV) ejection fraction (EF). Mean age at Mustard repair was 1.8 +/- 2.4 years and at initial exercise(More)
Information in 51 tape-recorded physician-patient encounters was compared with information written in the patients' medical records. Diagnoses, chief complaints, scheduled appointments, non-drug therapy, and diagnostic studies were uniformly well-recorded. Medication names were well-recorded but dosages were not. Characteristics of care such as levels of(More)
The natural history of patients with severe nonischemic mitral regurgitation (MR) from mitral valve prolapse, who are asymptomatic or minimally symptomatic and have normal right ventricular (RV) and left ventricular (LV) performance, has not been evaluated previously. To define natural history in this population and to determine if any objective variables(More)
To determine objective predictors of survival, 53 patients with chronic, hemodynamically severe mitral regurgitation underwent rest and exercise radionuclide cineangiography, echocardiography, treadmill exercise testing, and ambulatory electrocardiographic monitoring before prospective (average 30 month) follow-up. At entry, symptom status correlated best(More)
To examine the relation of short- and long-term changes in glucose metabolism to cardiac function, radionuclide cineangiography and echocardiography were performed in 10 young insulin-dependent diabetic patients without clinical evidence of heart disease. Cardiac assessments were performed before and after both acute variations in blood glucose, and(More)
To evaluate the relation of aortic root dilatation to aortic regurgitation, we examined clinical, echocardiographic, and radionuclide cineangiographic findings in 102 patients with severe aortic regurgitation. Aortic root dilatation was the only apparent cause in 31 patients (30%), exceeding in prevalence any valvular cause, and was independently associated(More)
Patients with mitral valve prolapse (MVP) may develop severe mitral regurgitation (MR) and require valve surgery. Preliminary data suggest that high body weight and blood pressure might add to the irreversible factors of older age and male gender in increasing risk of these complications. Fifty-four patients with severe MR due to MVP were compared with 117(More)
Although reduced heart rate (HR) variability during sinus rhythm is associated with an adverse prognosis in a variety of clinical settings, the significance of measures of variability of the ventricular response in atrial fibrillation (AF) requires clarification. AF is common among patients with chronic severe mitral regurgitation (MR) and potentially(More)
