BACKGROUND: Surgical skills acquisition in cardiac surgery requires consistent and hard practice. Furthermore, training using cadaver is advocated as a means of transferring learned skills to the operating room and recreate surgical situations for trainees to practice and hone their skills. We expose our experience in training for cardiac surgical procedures using human cadavers.
METHODS: From June 2013 to November 2016, we performed 302 cardiac surgical procedures on 50 human cadavers obtained according to the Ivorian laws in force. Cadavers were preserved in 10% formaldehyde and by cryopreservation.
RESULTS: In open heart, cardiac surgical techniques were achieved via sternotomy (n = 24) or via "lid-anterolateral thoracotomy" (n = 2). Pericardotomy (n = 26) and/or pericardiectomy (n = 26) were systematic. Aortic and caval canulations and pulmonary artery control (n = 30) were performed. After cardiotomy and arterial incisions (n = 34), 18 atrial and ventricular septal defects repair, 1 Fontan operation, 1 arterial switch, 11 enlargement procedures of the whole right ventricular outlet and 15 acquired valve heart diseases corrections were performed. In closed-heart surgery, procedures were achieved via sternotomy (n = 7), posterolateral thoracotomy (n = 12), or Marfan retroxiphoid approach (n = 3). Pericardotomy (n = 7) or pericardiectomy (n = 7) were performed. Great vessels dissections and expositions (n = 21) were achieved to perform 4 pulmonary artery bandings, 12 patent ductus arteriosus closures, 3 Waldhausen procedures, 7 Brock Operations, and 2 Blalock-Taussig shunts. In both situations, 29 direct pulmonary arterial, auricular, and ventricular sutures were achieved.
CONCLUSION: Surgical simulation in cadaver models offer an opportunity for trainees to practice their surgical skills before entering operating room.
