Randomized Controlled TrialEffect of preoperative angiotensin converting enzyme inhibitor or angiotensin receptor blocker use on the frequency of atrial fibrillation after cardiac surgery: a cohort study from the atrial fibrillation suppression trials II and III.
Two recent meta-analyses demonstrated that angiotensin converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) reduce the risk of developing new-onset atrial fibrillation (AF) by nearly 50%. However, the ability of ACEIs or ARBs to prevent postoperative atrial fibrillation (POAF) after cardiac surgery has not been adequately evaluated. ⋯ Although preoperative ACEI or ARB use reduced the odds of developing POAF by 29%, this association with not found to be statistically significant. A study with approximately 600 subjects would be needed to discern if ACEIs or ARBs truly impact POAF.

Changes in B-type natriuretic peptides after surgical ventricular restoration.
The aim of this study was to prospectively investigate changes in brain natriuretic peptide (BNP) and amino terminal pro-BNP (NT-pro-BNP) in relation to functional status after surgical ventricular restoration (SVR). ⋯ Heart failure secondary to post-infarction left ventricular remodeling can be reversed by SVR. Improvement in these patients was associated with reduced levels of B-type natriuretic peptides 6 months after surgery. Clinical improvement was maintained and peptide levels were further reduced at late follow-up.

Right ventricular outflow tract obstruction after arterial switch operation for the Taussig-Bing heart.
Incidence of right ventricular outflow tract obstruction (RVOTO) may be suspected to be higher after arterial switch operation (ASO) for Taussig-Bing heart than after ASO for transposition of the great arteries (TGA), as Taussig-Bing anomaly is frequently associated with aortic arch obstruction and subvalvular aortic stenosis. We evaluated the risk to develop RVOTO after ASO for Taussig-Bing heart. ⋯ Postoperative right-sided obstruction occurs more frequently after ASO repair of Taussig-Bing heart than after TGA arterial switching, leading to higher reintervention rate. Resection of the commonly associated subaortic stenosis often prevents RVOTO development.

Case ReportsTraumatic free wall and ventricular septal rupture - 'hybrid' management in a child.
A 8-year-old boy showed a traumatic ventricular septal rupture following a blunt chest trauma, and was scheduled for elective catheter closure. Two weeks later, a follow-up echocardiogram revealed a pseudoaneurysm of the anterior wall of the left ventricle. ⋯ Symptoms and signs seen in patients with ventricular pseudoaneurysms appear to be discrete and variable, and a high clinical index of suspicion with a very close echocardiographic follow-up is strongly recommended after occurrence of a blunt cardiac trauma. The combined 'hybrid' approach of transcatheter closure of the intraventricular rupture followed by surgical closure of the pseudoaneurysm allows for a less invasive and efficient management of this rare combination of post-traumatic ventricular free wall and septal rupture in a child.

Late coronary artery lesions after neonatal arterial switch operation: results of surgical coronary revascularization.
To evaluate the results of surgical revascularization in children with coronary artery lesions following neonatal arterial switch operation (ASO). ⋯ (1) Following ASO, coronary lesions are not uncommon and they are progressive. Routine and sequential coronary evaluation is necessary. (2) Coronary revascularization can be achieved using coronary angioplasty in most cases. Mammary bypass may be used in selected circumstances. Normal myocardial perfusion is restored in most patients.
