Thirty-five consecutive patients with unilateral posterior dislocation of the hip were studied for complications at an average follow-up of 4.6 years (range 2–10 years). Thompson–Epstein type IV dislocation was most frequent (10/35), reflecting an increase in high-speed motor vehicles in the developing countries. It is also a severe injury that leads to a(More)
INTRODUCTION Sites of complex fractionated atrial electrograms (CFAEs) and highest dominant frequency (DF) have been proposed as critical regions maintaining atrial fibrillation (AF). This study aimed to determine the minimum electrogram recording duration that accurately characterizes CFAE or DF sites for ablation without unduly lengthening the procedure.(More)
OBJECTIVES The purpose of this study was to determine whether patients with paroxysmal "lone" atrial fibrillation (AF) have an abnormal atrial substrate. BACKGROUND While "AF begets AF," prompt termination to prevent electrical remodeling does not prevent disease progression. METHODS Twenty-five patients with paroxysmal lone AF, without arrhythmia in(More)
Patients with atrial fibrillation (AF) are at an increased risk of thromboembolism and stroke primarily from the development of thrombi within the left atrium. Pathological changes in blood constituents and atrial endothelial damage promote left atrial thrombus formation. It is not known whether factors predisposing to left atrial thrombus formation in AF(More)
Accurate quantification of chimerism and microchimerism is proving to be increasingly valuable for hematopoietic cell transplantation as well as non-transplant conditions. However, methods that are available to quantify low-level chimerism lack accuracy. Therefore, we developed and validated a method for quantifying chimerism based on digital PCR(More)
The number of patients with implantable cardioverter-defibrillator (ICD) is rapidly increasing due to their expanding indications. Amongst the various types of electromagnetic interferences, little is reported about the effects of radiotherapy. We report a case of electrical reset of a single chamber ICD by scattered irradiation from radiotherapy.
PURPOSE The diagnostic value of examinations performed with the use of pocket-size echocardiograph by medical professionals with different levels of experience remains to be determined. The aim of this study was to assess the diagnostic value of bedside echocardiographic examinations performed with the use of pocket-size echocardiograph by experienced(More)
BACKGROUND This study was undertaken to determine the prevalence of coronary artery disease in patients with rheumatic heart disease undergoing valve surgery. METHODS AND RESULTS Consecutive patients with rheumatic heart disease (n=376) who were above the age of 40 years, and scheduled for valve surgery underwent diagnostic coronary angiogram to delineate(More)
AIMS To characterize the atrial remodelling in mitral stenosis (MS). METHODS AND RESULTS Twenty-four patients with severe MS undergoing commissurotomy and 24 controls were studied. Electrophysiological evaluation was performed in 12 patients in each group by positioning multi-electrode catheters in both atria to determine the following: effective(More)
Atrial fibrillation (AF) is the most common sustained arrhythmia to occur in humans. Several predisposing substrates such as increasing age, heart failure, hypertension and valvular heart disease have been identified. The use of illicit drugs as the substrate for AF is not frequently recognized.
