Osteoporosis, a major risk factor for sternum-related morbidity after median sternotomy, is quite prevalent among the elderly. In this prospective study, we investigated the potential of sternal protection by use of the "sternal wrapping method" in elderly osteoporotic patients who were undergoing median sternotomy. For this study, we chose 100 elderly osteoporotic patients who were scheduled to undergo median sternotomy. ⋯ Sternal wrapping using polyvinyl chloride tubes provides mechanical protection and, apparently, less postoperative chest pain and shorter hospitalizations. Probably, it reduces sternum-related complications, particularly in high-risk patients. Its benefits, however, should be confirmed in larger studies.

Air embolism is rare and potentially fatal. Its early recognition and prompt treatment can help to prevent life-threatening sequelae. Herein, we report the case of a 75-year-old man who underwent a computed tomographic-guided lung biopsy of a left-lower-lobe pulmonary nodule. ⋯ After 4 hours, computed tomography revealed that the air had been absorbed into the circulation. The patient had no residual neurologic deficits. In addition to reporting this case, we discuss possible causes of air embolism and the management of the condition after percutaneous lung biopsy.

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.

A 45-year-old man underwent repair of a congenital bicuspid aortic valve and complex aortic-root aneurysm with an aortic-root xenograft. A CentriMag® left ventricular assist device was implanted for cardiac support and was subsequently replaced with a HeartMate II® left ventricular assist device. ⋯ The patient underwent thrombus removal, oversewing of the prosthetic valve, and bypass of the left anterior descending coronary artery. This case emphasizes the hazard of bypassing a failed left ventricle with a cardiac assist device after aortic valve replacement, even with a bioprosthesis.
