Congenital anomalies of the mitral valve are rare. A mitral arcade is defined as a fibrous continuity between the papillary muscles and the anterior mitral leaflet creating a hammock like suspension. We present images of a mitral anomaly that consists of a direct attachment of the anterolateral papillary muscle to the anterior mitral leaflet, which we have labeled as a "hemi-arcade." We discuss the surgical findings and review the available literature regarding a mitral "arcade".

Management of the metallic foreign body in the heart remains controversial. Evaluation of possible methods for this issue and its possible treatments are discussed, the results of which may lead to a more effective strategy for management of intracardiac foreign bodies.

A growing number of patients have undergone the Mustard procedure for transposition of the great arteries, after which the morphologic right ventricle serves as the systemic ventricle. If this ventricle fails, ventricular assist device support may be necessary, but implanting the inflow cannula can be challenging in these patients because of the moderator band and trabeculation of the morphologic right ventricle. We describe successful assist device implantation in a 34-year-old patient who had undergone the Mustard procedure in infancy.

Case Reports
Radiofrequency ablation under extracorporeal membrane oxygenation for atrial tachycardia in postpartum.
Tachycardia-mediated cardiomyopathy associated with cardiogenic shock is a rare but well-known entity. We report an unusual case of cardiogenic shock with atrial tachycardia in postpartum; the patient underwent successful radiofrequency ablation under extracorporeal membrane oxygenation (ECMO). Radiofrequency ablation is usually used to treat this clinical situation. The use of ECMO has been described only in pediatric case.

We describe a technique that implants a rigid tricuspid annuloplasty ring over a previously inserted flexible ring for the treatment of recurrent tricuspid regurgitation. This technique avoids the trauma associated with the excision of a flexible ring in patients with friable annular tissue.
