A 56-year-old woman was underwent mitral valve repair for prolapse of the posterior mitral leaflet. Intraoperative transesophageal echocardiography (TEE) showed systolic anterior motion (SAM) of the mitral valve at the weaning from cardiopulmonary bypass (CPB). Sliding technique was easily performed at the second pump run. Intraoperative TEE demonstrated no SAM or residual mitral regurgitation after the second pump run.

Recently, an increasing number of patients have been treated with the Nuss procedure for pectus excavatum. One of the merits is that this surgical procedure is less invasive and leads to good cosmetic results compared with the former traditional procedures such as sternal turn over. We have repaired 60 cases of pectus excavatum using the Nuss procedure at our institute since July 1999. We have experienced the removal of a steel bar, which was the first case of Nuss procedure at our institute.

Tetralogy of Fallot with absent pulmonary valve has been classified to a few groups. The most severe one is characterized by symptomatic onset immediately after birth. The others are no or slightly symptomatic at least during their neonatal period. ⋯ Generally, to diminish the massive pulmonary regurgitation in early lifetime period could reduce a progressive airway obstruction and minimize pulmonary tissue damage. However, even after the total correction in this case, considerable peripheral segmental pulmonary obstructive lesions were persistent according to the perfusion lung scanning with 99mTc macroaggregated albumin and 99mTechnegas ventilation lung scanning studies. This persistent, supposed to be innate, pulmonary obstructive lesions might prevent ordinal recovery after cardiac radical repair for this most severe subtype of absent pulmonary valve syndrome.

We experienced a case of operation for acute type A aortic dissection using transapical aortic cannulation (TAC). A 62-year-old male with chest and back pain admitted to our hospital. ⋯ The reason why we use TAC is that retrograde perfusion by femoral artery has a high-risk of malperfusion and cerebral embolism because of atheromatous change in aorta, and the use of the axillary artery can be troublesome because of the vessel's small diameter. We considered that in cases of acute aortic dissection, TAC is much safer and simpler than femoral or axillary cannulation.
