ABSTRACT
OBJECTIVES: Gaining cardiac surgical competence is a complex, multifactorial process that may take years of experience and on-the-job training. It is critical to provide suitable educational opportunities to gain the necessary knowledge, judgment and skills. In response to the multitude of factors (e.g. European Working Time Directive) currently influencing cardiac surgical training, there have been concerted efforts to reform training practices. Simulation plays an increasingly important role in the educational process and serves to fill the most important gap in the current training model, i.e. operative exposure. Therefore, a contest has been written out for cardiac surgical trainees to construct their own coronary anastomosis simulator using everyday materials. METHODS: Cardiac surgical trainees were invited to construct their own coronary anastomosis simulator. An international jury of cardiac surgeons assessed the simulator and its presentation according to preset developmental criteria (low fidelity concept, innovative character, general presentation and description, general attractiveness to the scholar, ergonomical issues, perceived haptics, number of applicable components, transportability, ease of construction, repeatability and overall costs of the simulator). RESULTS: Six prototypes of simulators built by cardiac surgical trainees were generated. A general evaluation of each simulator prototype is provided according to the preset developmental criteria. CONCLUSIONS: All simulator prototypes have provided a considerable contribution to the field of surgical simulation. By designing simulator prototypes, the trainees have demonstrated their 'out of the box' thinking capability, which is of paramount importance for the development of future innovative surgical techniques and procedures. The Valladolid cardiac team coronary anastomosis simulator box was selected for the EACTS Ethicon Simulation Award 2011. This project will be mass produced and distributed to the participants of structured simulation sessions for coronary anastomoses.

The superior vena cava syndrome encompasses a constellation of symptoms and signs resulting from obstruction of the superior vena cava. We report a successful surgical management after failed endovascular stenting for superior vena cava syndrome, caused by a postradiation fibrosis after conventional radiotherapy for breast cancer. We emphasize the rarity of this uncommon surgical procedure and the bailout procedure for failed angioplasty and intravascular stenting. Key points of superior vena cava syndrome and its management are discussed.

Since 1998, a large body of literature regarding off-pump coronary bypass surgery has been published, although varying techniques and outcomes likely have led to its inconsistent application. One approach has been developed and standardized at the University Hospitals Leuven, Campus Gasthuisberg, Leuven, Belgium. This approach is straightforward and can be replicated without need for conversion toward cardiopulmonary bypass. The patient is 'conditioned' before and during the procedure. Both mammary arteries are harvested through a standard median sternotomy. The anterior surface of the heart is exposed with a horizontal line of left-sided pericardial stitches, just above the level of the heart. The anterior coronary vessels are anastomosed after routine shunting. The lateral and inferior aspects of the heart are exposed without deforming the atrio-ventricular axis. This is performed in a stepwise manner. The first step is anchoring a sling into the posterior pericardium under the roof of the left atrium. Second, this sling is gradually pulled upwards, supporting the heart as a cradle. Once the heart is exposed towards the zenith, an apical suction device stabilizes, reformats and exposes the ventricle. The lateral and inferior walls are then revascularized. As a strict no-touch aorta technique is used, free grafts are anastomosed to in-situ arterial grafts.
