Pulmonary artery cannulation to enhance extracorporeal membrane oxygenation management in acute cardiac failure.
Pulmonary artery (PA) cannulation during peripheral venoarterial extracorporeal membrane oxygenation (ECMO) has been shown to be effective either for indirect left ventricular (LV) unloading or to allow right ventricular (RV) bypass with associated gas-exchange support in case of acute RV with respiratory failure. This case series reports the results of such peculiar ECMO configurations with PA cannulation in different clinical conditions. ⋯ Effective indirect LV unloading in peripheral venoarterial ECMO as well as isolated RV support can be achieved by PA cannulation. Such an ECMO configuration may allow the counteraction of common venoarterial ECMO shortcomings or allow dynamic/adjustable management of ECMO according to specific ventricular dysfunction and haemodynamic needs. Percutaneous PA cannulation was shown to be safe and feasible without major complications. Additional investigation is needed to confirm the safety and efficacy of such an ECMO configuration and management in a larger patient population.

Five-year follow-up of transvenous and epicardial left ventricular leads: experience with more than 1000 leads.
Transvenous coronary sinus leads are considered to be the gold standard for cardiac resynchronization therapy (CRT). However, in patients with abnormal coronary vein anatomy, the epicardial leads can be an alternative. Data comparing durability and performance of these 2 lead types are limited. In order to provide clarity, we investigated patients receiving CRT system in our centre. ⋯ Our data demonstrate safety and functional efficacy of both transvenous and epicardial leads. Moreover, in long-term follow-up, a commendable durability and performance were found for both lead types. Thus, epicardial leads represent a good alternative when transvenous implantation fails.

Late surgical conversions after abdominal endovascular aortic repair: underlying mechanisms, clinical results and strategies for prevention.
Our goal was to report our results of late surgical conversion after endovascular aneurysm repair (EVAR). ⋯ Despite being a challenging operation, late surgical conversion after EVAR yields excellent results with regard to outcome and freedom from the need for further aortic interventions. An anticipative strategy adhering to current recommendations for using or refraining from using EVAR in patients with anatomical challenges will help reduce the need for secondary surgical conversions and keep them to minimum.

Outcomes of mitral valve repair in acute native mitral valve infective endocarditis.
Mitral valve repair (MVR) is considered the treatment of choice for mitral valve (MV) regurgitation. However, MVR in acute native MV infective endocarditis is technically challenging and not commonly performed. Our goal was to report our outcomes of MVR in acute native MV infective endocarditis. ⋯ Although MVR in acute native MV infective endocarditis is a complex procedure, it offers a treatment option for such patients with acceptable short-term results. Limited resection in addition to annuloplasty is our preferred method of repair. Nevertheless, long-term results in a larger cohort are still mandatory.
