A 47-year-old Malay woman complained of an episode of shortness of breath after a shower. There was no previous complaint of shortness of breath or chest pain. Physical examination revealed a wide pulse pressure. Blood pressure was 160/66 mmHg, and heart rate was 77/minute and regular. What was initially thought to be a loud pansystolic murmur was heard(More)
In 1994, all emergency medical services (EMS) ambulance officers in Singapore were trained to perform pre-hospital defibrillation with semi-automated external defibrillators (AED). All non-traumatic cardiac arrest patients over 10 years old were included, excluding those who were obviously dead and children below 36 kg. The data were collected by the(More)
A 36-year-old asymptomatic Chinese male with polycystic kidney disease (PKD) developed hypertension 1 year after the diagnosis of PKD. The patient was treated initially as for hypertension associated with PKD. However, over a 6-year period his hypertension became progressively difficult to control and he developed severe symptomatic hypokalemia. Subsequent(More)
Transoesophageal echocardiography (TEE) has earned an important role in the evaluation of patients with cardiovascular diseases. We report our TEE experience in 901 patients who had suboptimal transthoracic echocardiographic studies performed between September 1989 and June 1993. The patient-population consisted of 459 females and 442 males, with an ethnic(More)
Between June 1990 and August 1991, 28 percutaneous transseptal balloon mitral valvotomy procedures were attempted in 27 patients (23 women and 4 men; mean age 39.8 +/- 9.3 years) with severe mitral stenosis. Successful mitral valvotomy was achieved in 25 patients (primary success rate of 92%). Mitral valve area increased from 0.82 +/- 0.17 cm2 to 1.53 +/-(More)
A young man with a history of deep vein thrombosis and pulmonary embolism 11 years ago presented again with acute pulmonary embolism and was treated initially with intravenous heparin at our institution. Five days later he had another massive bout of pulmonary embolism causing hypotension. Pulmonary angiography confirmed the presence of thrombi in both(More)
Neuronal migration disorders are an uncommon but well-recognised cause of medically intractable epilepsy. The increasing availability of magnetic resonance imaging of the brain has made it possible to diagnose this condition ante-mortem. There are several types of migration disorders, each with different radiological and clinical features. A case each of(More)
The introduction of transoesophageal echocardiography has provided another acoustic window to the heart and mediastinum. The unique relationship of the esophagus to the heart and thoracic aorta has made transesophageal echocardiography ideal for imaging and assessment of the mitral valve particularly mitral prosthesis, atrial appendages, atrial septum,(More)
The management of patients with cardiovascular disease requires a comprehensive evaluation of both morphological and pathophysiological abnormalities associated with the disease process. To this end, a diagnostic technique that is noninvasive, painless, biologically safe, readily repeatable, economical and highly accurate would be ideal. The echo-Doppler(More)
