Case ReportsMassive pulmonary embolism in pregnancy treated with streptokinase and percutaneous catheter fragmentation.
Despite heightened awareness, pulmonary embolism remains a major cause of maternal mortality in the antenatal period and one which has not decreased in incidence over the four triennia since 1976. We report a patient who suffered massive pulmonary embolism with circulatory collapse in the second trimester and who was treated with intravenous streptokinase followed by percutaneous mechanical dispersion of thrombus using a catheter and guide wire. She made an excellent recovery despite complicating antepartum haemorrhage. In life-threatening circumstances pharmacological thrombolysis is mandatory particularly for hospitals without a cardiac catheterization laboratory on site.

Altered left ventricular diastolic function post-atrial pacing in coronary artery disease and left ventricular hypertrophy: further insights by pulmonary venous flow analysis.
Left ventricular filling dynamics during acute pacing-induced myocardial ischaemia were assessed using transoesophageal atrial pacing and simultaneous Doppler measurements of pulmonary venous and mitral flow. All patients (10 with CAD and 12 with left ventricular hypertrophy due to hypertrophic cardiomyopathy; HCM) were in sinus rhythm and patients with mitral insufficiency were excluded. Data were compared with those of a control group (n = 10). ⋯ Pacing resulted in significantly different changes in the TVI E/A ratio and the TVI of the retrograde pulmonary venous flow for CAD and HCM patients compared with those of control subjects. In patients with CAD and HCM, rapid atrial pacing results in a decreased early to late ventricular filling ratio because of impaired relaxation, despite presumably increased filling pressure. Retrograde pulmonary venous flow increased because of increased filling pressure and operating left ventricular stiffness.

Improvement in left ventricular dysfunction after aortic reimplantation in 11 consecutive paediatric patients with anomalous origin of the left coronary artery from the pulmonary artery. Early results of a serial echocardiographic follow-up.
To study the potential for recovery of left ventricular function in patients with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) after aortic reimplantation, serial two-dimensional echocardiographic examinations were performed before and up to 9 months after operation in 11 consecutive paediatric patients (group 1: six infants; group 2: five children above the age of 1 year). End-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), ejection fraction (EF), myocardial volume (MV), ratio of myocardial volume/end-diastolic volume (MVI), and regional wall motion of the left ventricle (LV) were studied. ⋯ In both groups mean LVEF reached the normal range after 3 months; LVMV as well as LVMVI normalized after 9 months. Three months after the operation, all infants had a nearly normal pattern of regional wall motion, while in three group 2 children a residual reduced shortening fraction could be observed in anterior or lateral segments.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical experience with propafenone for cardiac arrhythmias in the young.
Seventy-two children were treated with propafenone between 1980 and 1990. The mean age was 34 months (range 0-192). Arrhythmias included atrioventricular re-entry tachycardia in 32 patients (44%), atrial flutter in 16 (22%), atrial or junctional ectopic tachycardia in 10 (14%), atrial re-entry tachycardias in three (4%) and ventricular arrhythmias in 11 patients (16%). ⋯ Better results were observed in patients with normal hearts and in whom onset of arrhythmia was pre-natal (success 80%) as well as in patients with arrhythmias seen early after surgery for congenital heart defects (success 87%). Success (65%) was also observed in patients without congenital heart defects and postnatal onset of supraventricular arrhythmias. Patients with ventricular or supraventricular arrhythmias late after corrective surgery showed the poorest response (31%).

Comparative StudyFatal road accidents caused by sudden death of the driver in Finland and Vaud, Switzerland.
We investigated the incidence of fatal traffic accidents caused by sudden incapacity of the driver due to cardiac and other illnesses. The retrospective analysis was gleaned from Finnish traffic accident data files from 1984-1989, and police records of traffic accidents, from Canton de Vaud, Switzerland from 1986-1989. The annual rates of all traffic fatalities per million inhabitants were 125 in Finland and 212 in Vaud. ⋯ Accidents caused by sudden incapacity of the driver are rare causes of traffic deaths and hard to foresee. While this report relates to all drivers, we suggest there should be individual risk stratification for professional drivers with heart disease. However, non-professional drivers who are elderly and who have symptomatic cardiac disease should limit their driving to short distances and at low speed.
