Minimally invasive aortic valve replacement through a right mini-thoracotomy is a procedure developed in the past few years. Currently, the main limits of this technique are longer cardiopulmonary bypass time compared with the standard approach and the need for peripheral cannulation. ⋯ Our initial series confirms that aortic valve replacement performed through a right mini-thoracotomy is a safe procedure. When using running sutures, it is possible to obtain cardiopulmonary bypass and cross-clamping times comparable to those for the standard approach. A central cannulation can be performed easily to avoid groin incisions. In conclusion, we believe that this kind of surgery could really be a biologically minimally invasive approach, rather than just an aesthetic choice.

Adoption of simulation skills training in cardiothoracic (CT) surgery remains a challenge. This study sought to determine whether a "Top Gun" competition would encourage simulator use and improve technical skills among first-year CT residents. ⋯ Focused training results in improved technical skills in vessel anastomosis, especially for residents with lower baseline skills. Simulation, as with any educational endeavor, requires the motivation of the trainee, commitment of the faculty educator, and a defined training curriculum.

Thymoma patients with no prior history of myasthenia gravis (MG) occasionally have MG after thymectomy. This study aimed to identify risk factors for developing postthymectomy MG. ⋯ A positive result for serum AchR-Ab, type B1/B2/B3 thymoma histology, and incomplete resection were considered risk factors for the development of postthymectomy MG. Preoperative levels of serum AchR-Ab should be examined in all thymoma patients. Perioperative chemotherapy or radiotherapy for the patients with incomplete resection might reduce the risk of MG development.
