Case ReportsEmergency surgical extraction of rota ablator from the stent in the left anterior descending artery.
Trapping of interventional devices used to treat in-stent restenosis is rarely reported in the literature. Among those is a trapped rota ablation wire causing longitudinal stent deformation, sometime requiring another stent deployment onto the collapse stent. ⋯ During the procedure, the rota ablator got stuck into the stent resulting in haemodynamic compromise. To our knowledge, this is the first case where a rota ablator got stuck into the stent requiring surgical intervention.

Comparative StudyAortic valve reimplantation for large root aneurysm and high-grade aortic regurgitation: incidence and implications of additional cusp and commissure repair.
Large-sized root aneurysm and high-grade aortic regurgitation (AR) might be contraindications for a valve-sparing aortic root replacement procedure (V-SARR) and aortic valve repair. The impact of a combination of root reimplantation and additional cusp/commissure repair on valve sufficiency in this setting was investigated with respect to early- and mid-term functional outcome. ⋯ The setting of a large proximal thoracic aortic aneurysm size and high-grade AR does not result in a higher need for cusp/commissure procedures in order to achieve a satisfactory mid-term functional outcome. Large aneurysm size and high-grade AR per se do not increase the complexity of repair. The choice of reimplantation technique and prosthesis size selection might impact on mid-term valve function.

Technical and anatomical factors affecting the size of the branch pulmonary arteries following first-stage Norwood palliation for hypoplastic left heart syndrome.
Branch pulmonary artery (BPA) size is one of the factors that influence the efficacy of the Fontan circulation. Central pulmonary artery stenosis and small left pulmonary artery (LPA) are well-known problems following Norwood palliation for hypoplastic left heart syndrome (HLHS). We investigated anatomical and technical factors that may stand behind these problems. ⋯ Of all studied factors, IAR and the size and position of the pulmonary artery bifurcation plays the main role in LPA growth and central BPA stenosis.

Observational StudyAcute safety and efficacy of the NeoChord procedure†.
Transapical off-pump mitral valve repair using the NeoChord device has been proposed to treat degenerative mitral valve regurgitation. This prospective study sought to evaluate acute safety and efficacy of this innovative, minimally invasive, transcatheter mitral valve repair approach. ⋯ Initial results with the NeoChord procedure in a small number of patients indicate that transapical off-pump mitral valve repair is feasible and safe. Efficacy is maintained up to the 30-day follow-up with significant clinical benefit for patients.

Comparative Study Controlled Clinical Trial'Early' and 'late' timing for renal replacement therapy in acute kidney injury after cardiac surgery: a prospective, interventional, controlled, single-centre trial.
Acute kidney injury after cardiac surgery (CS-AKI) is strongly associated with in-hospital mortality and morbidity. We aimed to investigate whether 'early' or 'late' initiation of renal replacement therapy (RRT) in patients with CS-AKI is associated with a survival benefit or more favourable outcomes. ⋯ This trial is registered in the clinicaltrial.gov registry: NCT01961999.
