[Surgery of the left coronary trunk by the transpulmonary approach. 10 cases].

The most common lesions of the left main coronary artery are atheromatous lesions (1% of all "coronary patients") but traumatic lesions may occur during coronary arteriography or percutaneous coronary angioplasty. To these must be added severe infectious lesions of the aortic annulus in acute endocarditis affecting the valve or a valvular prosthesis. The 10 cases reported here (4 atheromatous, 1 traumatic and 5 infectious lesions) were treated by transpulmonary repair surgery of the left main vessel.

[Early coronary spasm after myocardial revascularization surgery].

Six cases of early post-operative coronary artery spasm were observed in a series of 460 consecutive patients who underwent myocardial revascularization. This is a rare accident, only quite recently described. The spasm involves the coronary arterial network or the graft and is reflected in an elevated ST segment accompanied by collapse and ventricular dysrhythmia.
