RESUMEN
The clinical importance of procedures for transvenous lead extraction has increased greatly because the volume of cardiac implantable electronic devices has increased. Consequently, the number of device-related complications requiring lead extraction has also been increasing. Great improvements in lead extraction techniques have occurred in recent years with the development of transvenous lead extraction tools and techniques. Experienced centres can achieve high success rates with infrequent complications. However, even in experienced hands, life-threatening complications can occur, and any physician performing these procedures must be prepared and trained for such eventualities. Moreover, because the occurrence of these stressful situations cannot be accurately predicted, training obtained in simulated environments can be decisive. We have developed a training module that simulates all the ordered steps of a transvenous lead extraction procedure and thus is able to help surgeons refine their surgical techniques and improve their performance.

Resumen La radioterapia mediastínica es uno de los tratamientos fundamentales de las enfermedades malignas torácicas, pero también representa una causa potencial de complicaciones, tanto a corto como a largo plazo. Se presenta una serie de casos de rotura de vena innominada durante esternotomía media en pacientes con fibrosis mediastínica. Los tres casos descritos corresponden a pacientes intervenidos de cirugía cardiaca con antecedentes de radioterapia mediastínica, entre 15-30 años antes de la cirugía, por tres diferentes enfermedades malignas (linfoma de Hodgkin, timoma y cáncer de mama). En los tres casos se reporta rotura de la vena innominada, con desinserción de su origen en la vena cava superior debido a fibrosis mediastínica intensa.
Abstract Although mediastinal radiotherapy is one of the basic treatments of malignant thoracic diseases, it is also a potential cause of short and long-term complications. A series of cases of rupture of the innominate vein during sternotomy are presented in patients with mediastinal fibrosis. The three cases described correspond to patients intervened by cardiac surgery, with a history of mediastinal radiotherapy between 15 to 30 years before the surgery, due to three different malignant diseases (Hodgkin lymphoma, thymoma, and breast cancer). In the three cases, a rupture of the innominate vein is reported; with de-insertion of its origin in the superior vena cava sue to intense mediastinal fibrosis.

We report a case of a 23-year-old man who was diagnosed with Kawasaki disease that progressed to a coronary aneurysm in the left main coronary artery (LMA). He had suffered from acute coronary syndrome and then underwent an emergent percutaneous coronary angioplasty, in which a polyurethane-covered stent was placed inside the aneurysm. The stent was thrombosed one year later, despite the patient had been treated with anticoagulant and antiplatelet therapy. Emergency percutaneous intervention was then performed. LMA was reopened and stent malposition was observed. Therefore, urgent coronary bypass grafting was performed in which a high degree of competitive flow was observed through the reopened stent. LMA was ligated at the inflow of the aneurysm, resulting in an improvement of graft flow. Left main ligature has not been previously reported.
