[Clinical case of the month. Spontaneous pneumopericardium after sternal dehiscence].

We report a case of pneumopericardium occuring after cardiac surgery. Pneumopericardium is a rare condition; trauma is the most frequent etiology. Nontraumatic causes include fistulae in relationship with the bronchial tree or oesophagus and intrapericardial gazeous production due to bacterial pericarditis.

The stress test is positive and the coronaro-angiographic evaluation demonstrates a coronary fistula between the left anterior descending (LAD) artery and the pulmonary artery trunk. The mid LAD presents a significant lesion after the origin of the fistula.

[Left ventricular aneurysms: principles of surgical treatment].

After reviewing the historical background, the morphology and physiopathology of left ventricular aneurysms, the authors review the physiology, the technical aspects, and the current surgical indications of aneurysmectomy, with a particular emphasis on the concept of endoventriculoplasty of Jatène & Dor.

[Clinical case of the month. Subvalvular aortic stenosis].

A case of fixed subvalvular aortic stenosis is reported. This clinical observation is the occasion to review the pathophysiology of this lesion and the last developments in the surgical treatment.
