Atrial septal defect due to blunt thoracic trauma.

The case report of an atrial septal defect with right-to-left shunting in an adult following blunt chest trauma is presented. To our knowledge a successfully repaired traumatic atrial septal defect has not been previously reported in the English-language literature.

Effects of contrast medium on left ventricular pressure and volume with emphasis on coronary artery disease.

Forty-one patients had left ventricular angiography repeated 3 minutes after an initial study in order to evaluate the effect of angiographic contrast medium on left ventricular end-diastolic pressure (EDP) and volume (EDV). Seven patients had no evidence of heart disease (normal group) and 34 patients had coronary artery disease. Single-vessel diseae was present in 10, double-vessel disease in 10, and triple-vessel disease in 14 patients.

Haemorrhagic pulmonary oedema: post-pulmonary embolectomy.

A case of haemorrhagic pulmonary oedema after successful pulmonary embolectomy is presented. The relevant literature is reviewed. Thirteen cases are analysed as well as the four survivors.

Response of the left ventricle in coronary artery disease to postextrasystolic potentiation.

Left ventricular volumes and contractile patterns were evaluated during the first sinus beat after a compensatory pause resulting from ventricular arrhythmia and were compared to the second sinus beat (control beat) in order to evaluate the effect of postextrasystolic potentiation. Twelve patients had no evidence of heart disease (group I). Fifty patients had coronary artery disease and included 14 patients (group IIa) with no prior myocardial infarction and a normal left ventricular contractile pattern and 19 pateints (group IIb) with an abnormal contractile pattern.
