Comparative StudyOncological outcomes of thoracoscopic thymectomy for the treatment of stages I-III thymomas.
Thoracoscopic thymectomy has gradually replaced conventional sternotomy for resection of thymoma; however, a thoracoscopic approach for thymoma remains controversial. We evaluated the oncological outcomes of thoracoscopic thymectomy for the treatment of stages I-III thymomas. ⋯ Thoracoscopic thymectomy for Masaoka stages I and II thymomas presented acceptable oncological outcomes. Further investigation in a large series with longer follow-up is required. Masaoka stage III thymoma requires careful consideration of the approaches, including median sternotomy.

B-type natriuretic peptide as a biochemical marker of left ventricular diastolic function: assessment in asymptomatic patients 1 year after valve replacement for aortic stenosis.
OBJECTIVES Left ventricular (LV) diastolic dysfunction after aortic valve replacement (AVR) carries a substantial risk of development of heart failure and reduced survival. In addition to echocardiography, B-type natriuretic peptide (BNP) provides a powerful incremental assessment of diastolic function. This study evaluates BNP as a marker of LV diastolic dysfunction in a cohort of patients with preserved LV ejection fraction who underwent AVR for pure aortic stenosis and the relationship between BNP values and the grade of LV diastolic dysfunction. ⋯ At receiver operating characteristic analysis, the BNP level of 120 pg/ml was 91% sensitive and 85% specific for diastolic disease, while 300 pg/ml was 80% sensitive and 91% specific for moderate or severe diastolic dysfunction. Twelve months after AVR, BNP values were strongly correlated with the significant echocardiographic parameters suggestive of diastolic dysfunction (P≤0.006 in all cases). CONCLUSIONS The BNP level following AVR is related to diastolic disease severity and may complement echocardiographic evaluation when symptoms are unclear and LV function is difficult to interpret.

Case ReportsParaprosthetic leak closure 28 years after mitral caged-ball Starr-Edwards implantation.
In this case report, we present a patient 28 years after mitral valve replacement with the Starr-Edwards prosthesis complicated by periprosthetic leak with severe aortic stenosis and moderate tricuspid regurgitation. We successfully repaired the periprosthetic regurgitation in a patient with extensive mitral annular calcification, without replacement of the valve. ⋯ Moreover, aortic valve replacement and tricuspid annuloplasty were performed. One month after reoperation, the patient remained stable with improved clinical status and without any evidence for further paravalvular leak.

Simple adaptations of surgical technique to critically reduce the risk of postoperative sternal complications in patients receiving bilateral internal thoracic arteries.
Limited blood supply to the thoracic chest wall is a known risk factor for sternal wound complications after CABG. Therefore, bilateral internal thoracic arteries are still rarely utilized despite their proven superior graft patency. The aim of our study was to analyse whether modification of the surgical technique is able to limit the risk of sternal wound complications in patients receiving bilateral internal thoracic artery grafting. ⋯ Adjusted for common risk factors, skeletonization of BITA grafts together with augmented sternal wires is effective in preventing sternal complications. The use of PRF sealant, however, increased the risk for superficial wound complications.

Modified Nuss procedure in the treatment of recurrent pectus excavatum after open repair.
The purpose of this study was to evaluate the efficacy of the modified Nuss procedure with a subxiphoid incision in correcting recurrent pectus excavatum. ⋯ The modified Nuss procedure with subxiphoid incision and bilateral thoracoscopy can avoid cardiac injury to the greatest degree. It would be a minimally invasive and safe approach for patients with recurrent pectus excavatum after failed open repair.
