Blunt chest trauma can cause serious complications, but coronary artery occlusion is rare. In a 19-year-old man, 40 days after a motorcycle accident, comprehensive echocardiography detected left anterior descending artery occlusion and left ventricular dysfunction, which was confirmed by coronary angiography and ventriculography. Echocardiography was also able to confirm restored ...

The management of congenitally corrected transposition of the great arteries and associated lesions is frequently challenging. Restrictive ventricular septal defect and mild pulmonary stenosis are contraindications to the double switch procedure, including the atrial-Rastelli switch procedure, due to the production of postoperative left ventricular outflow tract obstruction. We describe a ...

We report an unusual case of intrapericardial diaphragmatic hernia 2 years after coronary artery bypass surgery with the right gastroepiploic artery. Herniation through the orifice created for the right gastroepiploic artery caused small bowel strangulation and secondary volvulus requiring extensive small bowel resection due to acute mesenteric ischemia. This case highlights ...
