ABSTRACT: A 38-year-old man was diagnosed with acute type A aortic dissection and severe aortic regurgitation, and taken immediately to the operating room for repair of the ascending aorta using the Bentall procedure. The presence of the anomalous right coronary artery was revealed at the time of the procedure, and was repaired with single coronary button technique. Some case reports have described anomalous coronary artery in association with acute myocardiac infarction or angina pectoris. This report describes a case of anomalous coronary artery diagnosed during an emergency operation for aortic dissection.

ABSTRACT: Ventricular septal rupture (VSR) is an infrequent but life-threatening situation. Although outcomes have improved with the introduction of infarction exclusion, we have experienced difficulty in determining the optimal patch size and shape for obtaining good outcomes. Therefore, we modified the infarction exclusion technique. Herein, we review our experience on the basis of early closure of VSR with and without use of the infarction exclusion technique.
We retrospectively analyzed the hospital records of 33 patients who underwent surgical treatment for VSR. We employed Dagget's method from 1982 to 1995, and then introduced the infarction exclusion technique in 1995. We have developed two modifications: the two-sheet single-patch technique and the three-sheet double-patch technique.
Overall hospital mortality was 41.9% and that of the infarction exclusion group was significantly lower than the hospital mortality rate of the noninfarction exclusion group (21% and 63%, respectively, p = 0.0266). Late mortality of survivors was low in all groups during the observation period. The three-sheet double-patch group showed no residual shunt. This difference in outcomes between the single-patch and double-patch groups was statistically significant (p = 0.0174).
The two-sheet method facilitates the restoration of ventricular geometry. A double-patch using the three-sheet method may be useful for reducing residual shunt.

ABSTRACT: Closure of patent ductus arteriosus (PDA) in the elderly is a high-risk procedure due to the fragility of the aorta and aneurysmal changes in the ductus. Stent grafting has emerged as a method for treating aortic disease. We describe a case in which this endovascular technique was successfully performed for closure of a PDA with aneurismal change in a high-risk patient. This approach may comprise the armamentarium for treating this pathology in adults.

ABSTRACT: Median full-sternotomy carries a risk of sternal infection and lethal mediastinitis in cardiac surgery. We performed open-heart surgery through partial median sternotomy in 5 patients with tracheostomy. Coronary artery bypass grafting (CABG) was performed in 3 patients, aortic valve replacement in 1, and mitral valve replacement in 1. No operative deaths or complications related to wound infection occurred. Partial sternotomy represents a safe alternative in cardiac surgery in patients with tracheostoma.
