According to the 2007 American Thoracic Society/Infectious Diseases Society of America statement on nontuberculous mycobacterial diseases, more evidence for the benefits of adjuvant nontuberculous mycobacterial lung disease surgical intervention is needed before its wide application can be recommended. ⋯ Pulmonary resection combined with chemotherapy is safe, with favorable treatment outcomes, for patients with localized nontuberculous mycobacterial lung disease. Our results support the liberal use of operations for nontuberculous mycobacterial lung disease whenever indicated.

Comparative Study
Dilatation of the remaining aorta after aortic valve or aortic root replacement in patients with bicuspid aortic valve: a 5-year follow-up.
The natural history and management of ascending aorta (AA) and arch dilatation in patients with bicuspid aortic valve (BAV) after aortic valve replacement (AVR) or aortic root replacement (ARR) remains controversial. Our aim is to identify dilatation of the remaining aorta after AVR or ARR in patients with BAV compared with patients with tricuspid aortic valve (TAV). ⋯ No significant dilatation of the AA or arch was observed after AVR or ARR, respectively, in patients when a cut-off diameter of 4.5 cm or greater was considered for replacement in patients with BAV compared with patients with TAV up to 5 years after operation. The need for aortic replacement at smaller diameters was not found.

Ventricular septal rupture occurring as a result of blunt trauma is a very rare clinical condition. Compression of the heart between the sternum and the vertebral column during late diastole or isovolumetric contraction resulting in sudden increase in the intracardiac pressure is a prerequisite for its occurrence. Sudden relief of the inner pressure becomes impossible when the heart is full, thereby resulting in myocardial contusion and rupture. We report a case of a young schoolboy who presented to us with this serious disease and was successfully treated with surgical closure of the defect with a polytetrafluoroethylene patch.

Case Reports
Right ventricular outflow tract cannulation for right ventricular assist device implantation.
A need persists for implantable devices that provide support for the failing right ventricle. The anatomy of the right ventricle presents unique challenges at the time of right ventricular assist device implant. We describe a technique for right ventricular outflow tract cannulation that minimizes the risk of right ventricular assist device inflow cannula obstruction and right ventricular compression.
