AIMS To prospectively compare the agreement of left ventricular volumes and ejection fraction by M-mode echocardiography (echo), 2D echo, radionuclide ventriculography and cardiovascular magnetic resonance performed in patients with chronic stable heart failure. It is important to know whether the results of each technique are interchangable, and thereby(More)
OBJECTIVES Our study attempted to validate a Doppler index of diastolic filling (E/E') during exercise with simultaneously measured left ventricular diastolic pressure (LVDP), investigate its association with exercise capacity, and understand which patients to select for testing. BACKGROUND The ratio of early diastolic transmitral velocity to early(More)
BACKGROUND Intracardiac thrombus formation is a rare but serious complication of Behçet's disease. We aimed to review the clinical and pathologic correlates of cardiac thrombus formation in the context of Behçet's disease. METHODS AND RESULTS A comprehensive search of the medical literature was conducted using MEDLINE including bibliographies of all(More)
Exercise brachial blood pressure (BP) predicts mortality, but because of wave reflection, central (ascending aortic) pressure differs from brachial pressure. Exercise central BP may be clinically important, and a noninvasive means to derive it would be useful. The purpose of this study was to test the validity of a noninvasive technique to derive exercise(More)
OBJECTIVES We investigated the accuracy of automated analysis of myocardial deformation during dobutamine stress echocardiography (DSE). BACKGROUND The time required for segmental measurement of strain rate imaging (SRI) limits its feasibility for quantification of DSE. METHODS Myocardial deformation was assessed at DSE in 197 patients, 76 with and 61(More)
OBJECTIVES Tricuspid regurgitation (TR) is common after heart transplantation (OHT), but its clinical relevance is undetermined. This study documents the clinical progress of patients with TR after OHT in relation to the severity of TR. METHODS We studied 238 transplant recipients who had survived for at least 12 months after OHT. Tricuspid regurgitation(More)
OBJECTIVE The aim of this study was to compare the medium-term results of right heart pressures, tricuspid valve dysfunction, overall cardiac performance, and survival between the bicaval and standard techniques. METHOD Between 1991 and 1997, 201 heart transplantations were performed in our center. Right heart catheterization was performed up to 12 months(More)
BACKGROUND Tricuspid regurgitation (TR) may occur following orthotopic heart transplantation (OHT) and although a number of etiological factors have been suggested, the relative contribution of each of these remains to be elucidated. We aimed to assess the risk factors for TR in our 10-year experience of orthotopic heart transplantation (OHT). METHODS OHT(More)
To allow optimal patient management an ideal measure of right ventricular performance should give an accurate objective assessment of function, be practicable in everyday clinical use and provide accurate prognostic information. This review will provide the practising clinician with an understanding of the advantages and disadvantages of the available(More)
OBJECTIVES Cerebral microembolisation still occurs during cardiopulmonary bypass and may cause both stroke and postoperative cognitive impairment. We investigated the frequency of cerebral embolisation during coronary artery bypass surgery with modern cardiopulmonary bypass and related these to ascending aortic atherosclerosis. METHODS Transcranial(More)
