Transcatheter aortic valve implantation (TAVI) has become an emerging alternative for high-risk patients with aortic stenosis unsuitable for surgical intervention. We report the case of a 26-mm Edwards Sapien valve (Edwards Lifesciences, Irvine, CA) implanted into an insufficient 29-mm CoreValve prosthesis (Medtronic Inc, Minneapolis, MN) 1 year after implantation using the transapical approach in a 59-year-old man. ⋯ The balloon-expandable Sapien system caused a better expansion of the underdeployed CoreValve and the pericardial skirt adequately covered the leakage. The paravalvular regurgitation disappeared and the patient recovered.

Comparative Study
The impact of specific preoperative organ dysfunction in patients undergoing aortic valve replacement.
Optimizing treatment strategies to risk profile patients undergoing aortic valve replacement remains a priority. The role that specific and combinations of preoperative organ dysfunction (OD) plays in informing these decisions remains uncertain. This study sought to determine the relative effect that OD in particular systems has on short- and long-term outcomes. ⋯ The presence of chronic renal failure most profoundly decreases survival, followed by severe chronic obstructive pulmonary disease and prior stroke. Furthermore, multiple OD systems significantly decrease short- and long-term survival.

Comparative Study
Simulation-based postcardiotomy extracorporeal membrane oxygenation crisis training for thoracic surgery residents.
We developed and tested a clinical simulation program in the principles and conduct of postcardiotomy extracorporeal membrane oxygenation (ECMO) with the aim of improving confidence, proficiency, and crisis management. ⋯ We developed a simulation-based postcardiotomy ECMO training program that resulted in improved ECMO confidence in thoracic surgery residents. Crisis management in a simulated environment enabled residents to acquire technical and behavioral skills that are important in managing critical ECMO-related problems.

Comparative Study
Clinical outcomes of thoracoscopic lobectomy for patients with clinical N0 and pathologic N2 non-small cell lung cancer.
We compared the surgical outcomes in patients with clinical N0 and pathologic N2 (cN0-pN2) non-small cell lung cancer (NSCLC) who underwent video-assisted thoracoscopic surgery (VATS) lobectomy and open thoracotomy to evaluate the role of VATS lobectomy for cN0-pN2 disease. ⋯ The clinical outcomes of thoracoscopic lobectomy were comparable to those of thoracotomy for patients with cN0-pN2 NSCLC. Single-station N2 is a good prognostic factor for disease-free survival in these patients.

Pulmonary carcinoid and pulmonary lymphoma are both rare cancers and are seldom seen together. Cases have been reported of their coexistence in the gastrointestinal tract, but our literature searches only found a single case of their coexistence in the lung. We discuss our case as well as the literature to try to find a connection and explanation for this occurrence.
