A 67-year-old man on chronic hemodialysis was admitted with worsening congestive heart failure due to critical aortic stenosis. Echocardiography showed severe aortic stenosis with a valve area of 0.67 cm2 and an ejection fraction of 0.

The tumor was completely resected by lobectomy under cardiopulmonary bypass. The left SCA was dissected at the aortic arch and reconstructed with a graft.

We present two recent cases of mycotic aneurysm of the descending aorta complicated with hemoptysis. Urgent tube graft replacements were successfully performed under cardiopulmonary bypass support.

However, we no longer consider diabetes a reason for excluding the bilateral use of ITAs. We compare the early and long-term results in diabetic cases treated by coronary artery bypass grafting (CABG) using unilateral and bilateral ITA grafts.

Routine aortic arch replacement, irrespective of the location of the intimal tears, may improve not only the outcome of the residual dissection but the operative mortality, because complete resection of intimal tears, including those invisible through the aortotomy in the ascending aorta is achieved.
Methods: During the past 7 years, total aortic arch replacement was performed in 50 consecutive patients with acute type A aortic dissection.

Objective: Internal thoracic artery (ITA) grafts provide better early and long-term patency than saphenous vein (SV) grafts. Furthermore, bilateral ITA grafting has recently demonstrated better long-term results than unilateral ITA grafting. However, its use in the elderly is controversial.

Background: Operative mortality for a post-infarction ventricular septal defect (VSD) remains high. The infarct exclusion technique has been producing a favorable outcome for repairing this serious defect. However, there is the technical weakness, namely running suture along the base of the necrotic septum.

Conventional light microscopy revealed that cardiac myxoma and sarcoma cells presented variable cellular arrangements and different histological characteristics.

The mean age of 16 males and 3 females who underwent reoperation was 63.
View Article and Find Full Text PDFBackground: It has been demonstrated that bilateral use of internal thoracic arteries (ITAs) confers better long-term results in patients than does unilateral use. However, routine use of bilateral ITAs has usually been avoided.
Methods: Since 1997, we have used bilateral ITAs extensively for patients who required multivessel bypasses.
