Loeys-Dietz syndrome (LDS) is an aggressive aortopathy with a proclivity for aortic aneurysm rupture and dissection at smaller diameters than other connective tissue disorders. We reviewed our surgical experience of children with LDS to validate our guidelines for prophylactic aortic root replacement (ARR). ⋯ These data confirm the aggressive aortopathy of LDS. Valve-sparing ARR should be performed when feasible to avoid the risks of prostheses. Serial imaging of the arterial tree is critical, given the rate of subsequent intervention.

We wanted to assess the efficacy of curative intent pulmonary resection for non-small cell lung cancer (NSCLC) patients with synchronous M1b-distant metastases in a single organ or lesion. ⋯ Some M1b-cStage IV NSCLC patients achieved longer survival than others with the same stage disease by using local treatment for distant metastases and curative intent pulmonary resection. Oligometastatic patients might have been inadvertently included in the present cohort. However, at present, the optimum method for patient selection remains unclear.

Historically the most common causes of pericarditis necessitating pericardiectomy are infection, radiation, idiopathic causes, and inflammation. More recently, there has been a rise in iatrogenic pericardial constriction, with most cases occurring after coronary artery bypass grafting (CABG). To date, there has been no large series evaluating the incidence, presentation, and effectiveness of surgical intervention. We review our 20-year experience managing this special subset of patients. ⋯ The rate of early mortality for pericardiectomy after previous coronary bypass grafting is low, and the late adverse impact of cardiopulmonary bypass likely reflects increased severity of disease and technical complexity. Importantly, during late follow-up extending more than 17 years, the vast majority of patients demonstrated significant improvement in NYHA functional class.

Comparative Study
Efficacy of Aortic Valve Resuspension in Establishing Valve Competence in Acute Type A Dissections.
This study investigates the efficacy of aortic valve (AV) resuspension with preservation of the native aortic root in maintaining AV competence during type A dissection repair. ⋯ AV resuspension is able to improve valve competency with good outcomes even in patients with moderate or severe AI at presentation. Overall long-term survival is unchanged compared with other operative strategies for the AV.

The most striking feature of pectus excavatum (PE) after previous congenital heart disease (CHD) surgery through a median sternotomy is the postsurgical adhesions between the sternum and heart. For patients with severe adhesions, passing the introducer can be difficult and hazardous when performing a Nuss repair. We describe a hybrid Nuss procedure using a small subxiphoid incision for blunt and sharp anterior mediastinal dissection and using a thoracoscope to ensure the whole process of dissection is under direct visualization. ⋯ The hybrid Nuss procedure is a safe, simple modification of the Nuss repair for patients with severe retrosternal adhesions. This procedure achieves dissection with direct visualization. Hence, the risk of death due to cardiac perforation can be prevented.
