Case ReportsSafety of coronary artery bypass grafting in patients with bilateral total carotid occlusions.
The presence of bilateral carotid artery occlusions in patients that require coronary artery bypass surgery is rare. Here, we report the successful coronary revascularization of two patients with cardiopulmonary bypass under moderate hypothermia. ⋯ The vertebral blood flows of both patients were also found to be highly increased. Following successful surgery, the postoperative courses were uneventful and patients were discharged from the hospital on the seventh postoperative day.

Sutureless pericardial repair of total anomalous pulmonary venous connection in patients with right atrial isomerism.
Surgical repair of total anomalous pulmonary venous connection (TAPVC) in patients with right atrial isomerism is associated with a significant risk of recurrent pulmonary venous obstruction (PVO). We evaluate the effect of sutureless repair to reduce the risk of recurrent PVO. Since November 2007, five patients, including three neonates, with right atrial isomerism underwent sutureless repair of TAPVC. ⋯ Two patients underwent a bidirectional Glenn shunt after the sutureless repair. The pulmonary venous confluence was confirmed to be left open at the time of the Glenn surgery. The sutureless technique may be useful not only for postrepair PVO but also for non-operated TAPVC in neonates with right atrial isomerism.

Comparative StudyExtracorporeal membrane oxygenation to support adult patients with cardiac failure: predictive factors of 30-day mortality.
Adult patients supported on extracorporeal membrane oxygenation (ECMO) are very sick and many complications are often present in each single patient; therefore, it is not always easy to find some risk factors that can predict the early outcome. This retrospective study reports our experience in ECMO support treatment in adult cardiac patients suffering from cardiac failure (CF) in which one or more predictive factors of 30-day mortality were analyzed. Between January 2002 and August 2009, 42 consecutive adult cardiac patients with cardiogenic shock (mean age 64.3+/-11.3 years) were supported on ECMO for >2 days. ⋯ Stepwise logistic regression identified that blood lactate levels at 48 h and number of PRBCs transfused were associated with 30-day mortality [P=0.019, odds ratio (OR) =2.16; 95% confidence interval (CI)=1.13-4.14 and P=0.008, OR=1.08; 95% CI=1.02-1.14, respectively]. The predicted probability of mortality would be 52% when blood lactate levels are >3 mmol/l after 48 h. The blood lactate level at 48 h and PRBCs transfused per day can be considered as important parameters to predict the mortality in adult cardiac patients supported by ECMO for CF.
