Predictive models of prolonged air leak have relied on information not always available preoperatively (eg, extent of resection, pleural adhesions). Our objective was to construct a model to identify patients at increased risk of prolonged air leak using preoperative factors exclusively. ⋯ A subgroup of lung resection patients at higher risk for a prolonged air leak can be effectively identified with the use of widely available, preoperative factors. The proposed scoring system is simple, is clinically relevant to the informed consent, and allows preoperative patient selection for interventions to reduce the risk of prolonged air leak.

Comparative Study
Stent Grafting Acute Aortic Dissection: Comparison of DeBakey Extent IIIA Versus IIIB.
Thoracic endovascular aortic repair (TEVAR) with stent grafting is effective for acute dissection in selected patients, but most remain at risk for reintervention. The effect of the extent of dissection on outcome is unclear. Objectives of this study were to compare characteristics, outcomes, and aortic remodeling after TEVAR between patients with DeBakey extent IIIA and IIIB dissection. ⋯ In patients requiring TEVAR for acute dissection, patient factors and aortic morphology differ by the extent of the dissection. Aortic remodeling after TEVAR was better in patients with limited extent (IIIA) dissection than in than patients with extensive (IIIB) dissection. Despite these differences, very little difference was noted in early and late outcomes, which may be explained by differences in patient characteristics.

We assessed whether additional cusp repair during valve-sparing aortic root replacement affects the echocardiographic mid-term results; a subgroup analysis among patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV) was performed. ⋯ Adjunctive cusp repair seems to affect the mid-term reoperation risk in patients with BAV and not in patients with tricuspid aortic valve. We recommend caution in using this technique in case of asymmetric BAV requiring cusp repair.

We report a case of catastrophic hemodynamic compromise secondary to pannus ingrowth and severe mitral stenosis occurring years after repair of a nonrheumatic mitral valve. The initial repair included closure of a posterior leaflet cleft and implantation of an annuloplasty ring. We describe a hybrid treatment strategy for this severely compromised patient, which included initial placement of a right ventricular assist device followed by percutaneous balloon mitral valvuloplasty and, eventually, a definitive mitral valve reoperation. This case report reinforces the importance of routine clinical and echocardiographic follow-up for patients after mitral valve repair, and it includes the description of a novel therapeutic approach.
