Surgical angioplasty for ostial atresia of left main coronary artery in child.

Ostial atresia of the left main coronary artery (LMCA) in children without any primary disease is extremely rare. We present here a case of occlusion of the LMCA in a 9-year-old girl. Myocardial scintigraphy showed poor perfusion in both domains of the left anterior descending artery (LAD) and left circumflex artery (LCx).

Shaggy aorta syndrome after acute arterial macroembolism: report of a case.

We report the case of a patient who underwent treatment for a macroembolism in the right lower leg, which led to shaggy aorta syndrome. Anticoagulant therapy for the macroembolism and intra-aortic catheterization exacerbated the patient's renal function and triggered another massive microembolization of the visceral arteries, with a fatal outcome. To minimize the incremental complications inherent to this syndrome, awareness and prompt diagnosis with enhanced computed tomography or intravenous digital subtraction aortography are essential.

Spontaneous disappearance of a false aneurysm after iatrogenic ruptured ventricle.

We report the case of a 64-year-old woman who had an atypical subendocardial aneurysm, a space between the internal patch, which was used for the repair of a left ventricular rupture after mitral valve replacement, and myocardium, which filled with blood during the diastole phase. During the follow-up period, the aneurysm spontaneously disappeared. This case endorses combining internal and external approaches to repair a left ventricular rupture after mitral valve replacement.
