A 21-year-old man with coronary sinus atrial septal defect (ASD) was treated successfully. This case had been diagnosed as an ASD without a lower margin preoperatively but we confirmed this to be a coronary sinus ASD intraoperatively, and this case was classified as partially unroofed coronary sinus without PLSVC.The diagnosis of coronary sinus ASD before operation is sometimes difficult. Therefore we should pay attention to the location of the defect and the dilated coronary sinus in echocardiography, and the course of the cardiac catheter entering into the left atrium, for a correct diagnosis. In this case, the defect was located in the vicinity of the ostium of a large coronary sinus, therefore we could close the defect between the CS and the LA using a heart-shaped patch without any damage to the AV node.

In patients with so-called porcelain aorta characterized by calcification of the total aorta, manipulation of the ascending aorta can cause cerebral infarction and other conditions due to aortic dissection or rupture and calcified debris. In the present case with ischemic cardiomyopathy and porcelain aorta, an occlusion balloon catheter was inserted into the ascending aorta to avoid its clamping, followed by Dor operation and CABG under cardiac arrest with normothermic extracorporeal circulation. Techniques such as deep hypothermic circulatory arrest and surgery while the heart is beating are often currently used as auxiliary methods to avoid aortic clamp. However, the present case with insufficient left ventricular function required a left ventriculotomy, and thus the technique presented here is useful for shortening the surgical time and ensuring a reliable outcome of the operation.
A 52-year-old man with annulo-aortic ectasia and DeBakey's type IIIb dissecting aortic aneurysm was successfully treated. Aortography showed moderate to severe aortic regurgitation and enlargement of the ascending aorta, and CT showed a huge type IIIb dissecting aortic aneurysm. We scheduled a two-staged operation because dissection occurred 6 months previously and ECG showed severe LVH and ST-T change. The aortic root replacement using Bentall's procedure was performed, which was followed by arch replacement with an elephant trunk prosthesis on distal aorta. The entry in the distal aortic arch was covered by an elephant trunk prosthesis and postoperative diagnostic images showed thrombo-occlusion of the false lumen in the descending aorta. This operation was safe and might be a useful method for annulo-aortic ectasia with type IIIb dissecting aortic aneurysm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
