BACKGROUND The maternal and neonatal risks associated with pregnancy in women with heart disease receiving comprehensive prenatal care have not been well defined. METHODS AND RESULTS We prospectively enrolled 562 consecutive pregnant women with heart disease and determined the outcomes of 599 pregnancies not ending in miscarriage. Pulmonary edema,(More)
OBJECTIVE To examine the role of transoesophageal echocardiography in the assessment of patients with coronary artery anomalies. BACKGROUND Coronary artery anomalies are difficult to detect clinically. Most are benign but some may produce symptoms that can be life threatening. Until recently the non-invasive assessment of coronary artery anomalies has(More)
BACKGROUND Percutaneous transluminal coronary angioplasty (PTCA) is complicated by restenosis within 6 months in > 40% of patients. Theoretical, animal experimental, and human epidemiological and clinical trial findings have suggested that fish oils (n-3) might reduce restenosis. Low-molecular-weight heparin (LMWH) has reduced cellular proliferation and(More)
Various methods have been proposed and tried to limit the extent of myocardial damage at the time of infarction. We chose to assess the usefulness of intravenous magnesium in this regard because of its important role in myocardial metabolism and function and the suggestion of its deficiency in ischemic hearts. A double-blind randomized trial was carried out(More)
OBJECTIVES The prevalence and impact of longer-term outcomes following percutaneous tracheostomy, particularly tracheal stenosis, are unclear. Previous meta-analyses addressing this problem have been confounded by the low prevalence of tracheal stenosis and a limited number of studies. DESIGN Embase, PubMed-Medline, and the Cochrane Central Register of(More)
Torsade de pointes is a potentially lethal ventricular arrhythmia that is associated with prolonged QT intervals and is often caused by drugs that prolong repolarization. Among the most common drugs that may cause torsade de pointes are antiarrhythmic drugs including quinidine, procainamide, sotalol and newer class III antiarrhythmic agents. The incidence(More)
Myocardial infarction has been noted as a frequent complication of coronary artery surgery in many review series, although its causes are uncertain. Follow-up of 100 patients at 19.7 months (mean) after coronary bypass surgery identified 15 patients with perioperative myocardial infarction as judged by new, significant Q waves after surgery. There were no(More)
BACKGROUND The "weekend effect" describes an increase in adverse outcomes for patients admitted at the weekend. Critical care units have moved to higher intensity working patterns to address this with some improved outcomes. However, support services have persisted with traditional working patterns. Blood cultures are an essential diagnostic tool for(More)
Analyzing the digitized left ventricular cineangiograms of 70 patients with no demonstrable heart disease (NDHD), we derived an angiographic model for normal contraction in the intact heart as viewed in the 30 degree right anterior oblique projection. This model was verified statistically by comparing the predicted regional stroke volumes with the measured(More)
