Diverticulosis of the left ventricle.

Nine patients, 4--60 years old, had single or multiple left ventricular outpouchings, best seen during diastole, and believed to represent congenital diverticula. The 14 diverticula, 5--28 mm long, were either along the diaphragmatic or anterior ventricular wall. Only one patient had his diverticulum surgically removed; the wall was lined by thick endocardium surrounded by normal myocardium. The lesions did not produce local or systemic complications. All patients had normal chest radiographs. The material suggests that left ventricular diverticula not associated with midline anomalies are perhaps not very rare and should be distinguished from cardiac aneurysm.

Laryngotracheobronchitis: 2 years' experience with racemic epinephrine.

A relatively new form of treatment of laryngotracheobronchitis, administration of racemic epinephrine by intermittent positive-pressure breathing, was begun in 1973 in the pediatric unit of a large community hospital. A review of 2 years' experience with this treatment, compared with the experience of the 3 years prior to its introduction, has shown that it has reduced significantly the necessity for tracheostomy, to nearly zero, and the duration of hospital stay. A total of 119 children (33.15% of those admitted) received this treatment, the average number of treatments required being 1.8. There were no important complications of treatment and no deaths.

The effect of angiotensin-II during ventriculography in dogs with normal coronary arteries.

Left ventriculography was performed with and without angiotensin-II in dogs with normal coronary arteries. Concomitant administration of angiotensin significantly attenuated the myocardial depression associated with ventriculography. The beneficial effect of angiotensin may be due to its ability to maintain aortic diastolic pressure and thus flush the contrast material from the myocardium more rapidly, at least in animals without imposed coronary stenosis.

Correlation of vectorcardiogram and electrocardiogram with coronary arteriogram.

One hundred patients with suspected coronary heart disease were studied by vectorcardiography (VCG), electrocardiography (ECG), and coronary arteriography. Twenty-eight patients had VCG evidence of anterior infarction; 26 of this group had severe narrowing or obstruction of the left anterior descending branch. Five did not have anterior infarction by ECG. Twenty-seven patients had VCG evidence of diaphragmatic infarction; 25 of this group had severe narrowing of the right coronary artery or the left circumflex branch or both. Six of the 27 did not have ECG evidence of diaphragmatic infarction. Twelve patients had VCG evidence of posterior infarction whereas it was detected by ECG in only two. Only six of the 12, however, had severe narrowing of the nutrient arteries to the posterobasal part of the myocardium. Thirteen patients with infarction had severe narrowing but not total obstruction of a coronary artery. On the other hand, 15 patients had total obstruction of a major coronary vessel without actual infarction.
