Idiopathic giant cell myocarditis is a rare condition with a poor prognosis. Patients with giant cell myocarditis typically die of refractory ventricular arrhythmias or progressive congestive heart failure in about 3 months. The benefit of immunosuppressive therapy varies among patients with giant cell myocarditis, and no factors that would predict which patients will respond to therapy have been identified. ⋯ Herein, we describe a case of giant cell myocarditis in a previously healthy 44-year-old woman who presented with cardiogenic shock. She was supported hemodynamically with the Impella Recover LP 2.5 left ventricular assist device until a permanent device could be surgically implanted. To our knowledge, this is the 1st reported case of the successful use of the Impella device for hemodynamic support in a patient with giant cell myocarditis until more definitive treatment could be instituted.

We reviewed our department's experience with the perioperative features and surgical treatment of isolated right-sided infective endocarditis. From January 2000 through July 2010, 35 patients underwent surgery for isolated right-sided infective endocarditis in our department. The mean pathologic course was 3.6 months. ⋯ Of the patients who underwent tricuspid valvuloplasty, 23 had no valvular incompetence and 11 had mild or moderate regurgitation before discharge from the hospital. During follow-up, no patient needed reoperation because of reinfection, and 1 underwent reoperation for severe tricuspid regurgitation. We conclude that surgery can yield satisfactory immediate and midterm results in the treatment of isolated right-sided infective endocarditis.

Pulmonary valve leaflet extension with bovine pericardium: for treatment of pulmonary insufficiency.
Using a homograft in a pulmonic area is sometimes inadvisable due to the lack of optimal graft materials. We report a case of pulmonary valve insufficiency that we treated by leaflet extension using the commercially available E-Leafcon template and bovine pericardium. We suggest that this method can be an acceptable alternative for treating pulmonary valve insufficiency because the pulmonary valve area is similar to that of the aortic valve (for which application the template was designed). Further, the durability of bovine pericardium is comparable to that of a homograft or a xenograft.
