BACKGROUND Permanent pacemaker (PPM) requirement is a recognized complication of transcatheter aortic valve implantation. We assessed the UK incidence of permanent pacing within 30 days of CoreValve implantation and formulated an anatomic and electrophysiological model. METHODS AND RESULTS Data from 270 patients at 10 centers in the United Kingdom were(More)
Three cases of Wegener's granulomatosis with cardiac complications are described and the relevant published reports are reviewed. The first case of Wegener's granulomatosis was associated with aortic regurgitation and required aortic valve replacement. The second and third cases were associated with pericardial disease requiring pericardiectomy for(More)
BACKGROUND Transcatheter aortic valve implantation (TAVI) is associated with periprocedural and postprocedural morbidity and mortality. Currently, there is a paucity of risk stratification models for potential TAVI candidates. We employed the CHA2DS2-Vasc score to quantify the risk of 30-day mortality and morbidity in patients undergoing TAVI. METHODS AND(More)
A study of the neuromuscular features of acromegaly was performed in six patients. Clinical assessment was supplemented by quadriceps force measurements, plasma creatine kinase (CK) activities, electromyography (EMG) and nerve conduction studies. Muscle mass was measured by urinary creatinine/height indices (CHI) and cross sectional area (CSA) of thighs and(More)
OBJECTIVE To define the incidence, effects on functional abilities, and possible causation of heterotopic ossification (HO) in Guillain-Barré syndrome (GBS) patients admitted for inpatient rehabilitation. DESIGN Long-term prospective study on neurologic and functional outcome of GBS patients admitted for rehabilitation. SETTING Rehabilitation(More)
BACKGROUND The aim of the present study was to evaluate the utility of nuclear scintigraphic-labelled red cell scanning in the management of bleeding in patients with acute lower gastrointestinal haemorrhage (GIH) who require surgery. METHODS A prospective database was used to source data on all patients with lower GIH who underwent technetium-99m(More)
A transducer tipped catheter and simple recording system were used for the continuous measurement of ambulatory pulmonary artery pressure. The pulmonary artery pressure was recorded on a miniaturised tape recorder and replayed via an optical writer. Pulmonary arterial systolic and diastolic pressures can be analysed on a beat to beat basis. Continuous(More)
The objective of this study was to assess the changes in outcome of cardiac arrest due to ventricular fibrillation, asystole and electromechanical dissociation in relation to the changing guidelines for drug therapy set by the U.K. Resuscitation Council. It was a retrospective study of 667 resuscitation records for the years 1982, 1986, 1988, 1989, 1990 and(More)
