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.

To ascertain whether fluorodeoxyglucose positron emission tomography is indicated for clinical staging of superficial cancer, we sought to determine if it accurately classifies tumor (T), regional nodal (N), and distant metastases (M), including distinguishing high-grade dysplasia (Tis) from invasive cancer (T1). ⋯ Because positron emission tomography can neither differentiate pTis from T1 nor classify T, N, and M, it is not indicated in staging superficial esophageal cancer. Finding a synchronous primary tumor in approximately every 20th patient is its only benefit. Better, less expensive screening tools are available for common synchronous malignancies.

The optimal procedure for the great arteries and left ventricular outflow tract obstruction. An anatomical study.
To describe the optimal surgical strategy in heart specimens with transposition of the great arteries (TGA) and left ventricular outflow tract obstruction (LVOTO). ⋯ LVOTO resection and pulmonary valvotomy frequently permits an ASO. Inlet VSD, impossibility of VSD enlargement, straddling mitral valve, distant aorta and small right ventricle make the Nikaidoh procedure the best option. Mitral anomalies preventing LVOTO relief can make biventricular repair impossible.
