Treatment outcomes in 23 thoracic primitive neuroectodermal tumours: a retrospective study.

Objectives: Thoracic primitive neuroectodermal tumour is an aggressive malignancy with poor survival despite multimodality treatment regimens. Early diagnosis of the tumour by histological, immunohistochemical, ultrastructural and cytogenetic techniques and early total surgical resection of the tumour with intensive chemoradiation may improve outcomes.

Methods: Over 30 years, 23 patients (median age 29.

Surgery of the Ebstein's anomaly: early and late outcomes.

Background: Ebstein's anomaly of the tricuspid valve is a complex malformation. Several operations have been undertaken with varying results. The severity of the morphology of the lesion and ventricular function determine the spectrum of surgical techniques that are employed with varying results.

Chondroid syringoma: a rare tumor of the chest wall.

Chondroid syringoma, an uncommon, slow-growing, benign, sweat-gland tumor located on the upper right chest wall of a 66-year-old woman is presented. This skin adenexal tumor is typically located on the head and neck region. The unusual location of chondroid syringoma made an accurate preoperative diagnosis difficult, and diagnosis was achieved only by excisional biopsy and histopathologic examination.

Autogenous pericardial valve conduit for right ventricular outflow tract reconstruction.

Conduit failure is a common late complication of use of allogra0t conduits. Pericardial membrane valve conduits were used as an alternative to homografts for reconstruction of the right ventricular outflow tract (RVOT). A novel and expeditious technique of conduit reconstruction using autogenous and vascularized pericardium is described.

Results of coronary bypass and valve operations for mitral valve regurgitation.

Combined coronary bypass grafting and valve procedures for mitral valve regurgitation result in poor outcomes, but the impact of the etiology of valve regurgitation on operative and long-term outcomes is not well defined. A retrospective analysis of 468 patients who had combined coronary bypass grafting and valve operations for mitral regurgitation showed that 78% had valve repairs and 22% had replacements for ischemic (45%) or degenerative (55%) disease. Predictors of operative mortality were ischemic mitral regurgitation, failure to use the internal mammary artery for grafting, severe coronary disease, acute myocardial infarction, low ejection fraction, advanced heart failure, emergency operation, and mitral valve replacement.

Clinical outcomes of surgery of mitral valve regurgitation and coronary artery bypass grafting.

The impact of etiology of associated mitral valve regurgitation and a valve procedure on operative and long-term outcomes after coronary bypass grafting surgery is yet to be clearly defined. Results of combined coronary artery bypass grafting and valve procedures for mitral valve regurgitation were retrospectively analyzed in 468 patients. The regurgitation was of ischemic in 45%, degenerative in 55% and 78% valve repairs, 22% valve replacements were performed.

Results of coronary artery endarterectomy and coronary artery bypass grafting for diffuse coronary artery disease.

Background: Coronary artery endarterectomy with coronary artery bypass grafting for diffuse coronary artery disease has been associated with increased morbidity and mortality. We evaluated our institutional experience to redefine the role of coronary endarterectomy for diffuse coronary artery disease.

Methods: From 1985 to 2002 isolated coronary artery endarterectomy with coronary artery bypass grafting was performed in 1,478 consecutive patients.
