Case ReportsThoracoscopic anatomical subsegmentectomy of the right S2b + S3 using a 3D printing model with rapid prototyping.
Thoracoscopic segmentectomies and subsegmentectomies are more difficult than lobectomy because of the complexity of the procedure; therefore, preoperative decision-making and surgical procedure planning are essential. In the literature, we could successfully perform thoracoscopic anatomical subsegmentectomy of the right S2b + S3 using a 3D printing model with rapid prototyping. This innovative surgical support model is extremely useful for planning a surgical procedure and identifying the surgical margin.

Case ReportsOutflow graft thrombectomy during HeartMate II left ventricular assist device exchange.
We report the pump exchange secondary to a detached bend relief sheath of a HeartMate II (Thoratec Corporation, Pleasanton, CA, USA) left ventricular assist device, consistent with previous Food and Drug Administration warnings. This report highlights a thrombectomy technique and reuse of the outflow graft during subcostal pump exchange in a patient with relative contraindications to repeat sternotomy.

Case Reports'Fast-implantable' aortic valve implantation and concomitant mitral procedures.
Concomitant aortic and mitral valve replacement or concomitant aortic valve replacement and mitral repair can be a challenge for the cardiac surgeon: in particular, because of their structure and design, two bioprosthetic heart valves or an aortic valve prosthesis and a rigid mitral ring can interfere at the level of the mitroaortic junction. Therefore, when a mitral bioprosthesis or a rigid mitral ring is already in place and a surgical aortic valve replacement becomes necessary, or when older high-risk patients require concomitant mitral and aortic procedures, the new 'fast-implantable' aortic valve system (Intuity valve, Edwards Lifesciences, Irvine, CA, USA) can represent a smart alternative to standard aortic bioprosthesis. Unfortunately, this is still controversial (risk of interference). ⋯ Interestingly, we learned that there is no interference (or not significant interference) among the standard valve and the stent valve. Consequently, we can assume that a fast-implantable valve can also be safely placed next to a biological mitral valve or next to a rigid mitral ring without risks of distortion, malpositioning, high gradient or paravalvular leak. This paper describes two cases: a concomitant Intuity aortic valve and bioprosthetic mitral valve implantation and a concomitant Intuity aortic valve and mitral ring implantation.
