Sutureless aortic valve implantation through an upper v-type ministernotomy: an innovative approach in high-risk patients.
Aortic valve replacement in minimally invasive approach has shown to improve clinical outcomes even with a prolonged cardiopulmonary bypass and aortic cross-clamp (ACC) time. Sutureless aortic valve implantation may ideally shorten operative time. We describe our initial experience with the sutureless 3f Enable (Medtronic, Inc, ATS Medical, Minneapolis, MN USA) aortic bioprosthesis implanted in minimally invasive approach in high-risk patients. ⋯ The 3f Enable sutureless bioprosthesis implanted in minimally invasive approach through an upper V-type ministernotomy is a feasible, safe, and reproducible procedure. Hemodynamic and clinical data are promising. This innovative approach might be considered as an alternative in high-risk patients. Reduction of CPB and ACC time is possible with increasing of experience and sutureless evolution of actual technology.

Comparative StudyVideo-assisted thoracic surgery lobectomy versus lobectomy by thoracotomy for lung cancer: pilot study.
Video-assisted thoracic surgery lobectomy (VATS-L) has become accepted as a safe and effective procedure to treat early-stage non-small cell lung carcinoma (NSCLC). However, the advantages of VATS-L compared with lobectomy by thoracotomy (TL) remain controversial. The aim of this study was to compare the outcomes of patients who underwent VATS-L with those who underwent TL. ⋯ Our initial data suggest that VATS-L is a safe procedure in patients with resectable IA/IB NSCLC and may be the preferred strategy for treatment of the older patient population.

Comparative StudyAdvanced esophageal cancer in patients who underwent radiofrequency ablation for barrett esophagus with high-grade dysplasia.
We sought to evaluate clinicopathologic features of patients who underwent esophageal surgery after radiofrequency ablation (RFA) treatment using the HALO system for Barrett esophagus (BE) with high-grade dysplasia (HGD). ⋯ Radiofrequency ablation for BE with HGD may mask underlying esophageal cancer. Patients who are counseled to undergo RFA for HGD should be aware that RFA could lead to delayed diagnosis and delayed treatment of invasive esophageal cancer without careful patient selection, appropriate RFA use, and close surveillance.

Does dual antiplatelet therapy affect blood loss and transfusion requirements in robotic-assisted coronary artery surgery?
Patients who present for coronary surgery often receive preoperative dual antiplatelet therapy with aspirin and a thienopyridine derivative (clopidogrel or prasugrel), especially after a recent acute coronary syndrome. Studies have shown that patients on aspirin and clopidogrel are at increased risk for perioperative bleeding and related events. We sought to examine the impact of dual antiplatelet therapy on bleeding and transfusion requirements in patients undergoing robotic-assisted minimally invasive coronary artery bypass grafting. ⋯ Preoperative dual antiplatelet therapy does not result in significantly increased bleeding or perioperative transfusion requirements. If clinically indicated, it is reasonable to continue preoperative combination antiplatelet therapy in patients undergoing robotic-assisted coronary surgery.

Acute kidney injury after transcatheter aortic valve implantation: incidence, risk factors, and prognostic effects.
Acute kidney injury (AKI) is a common complication after surgical aortic valve replacement and is associated with increased mortality. Transcatheter aortic valve implantation (TAVI) is now considered the criterion standard treatment of patients with severe symptomatic aortic stenosis ineligible for surgery. The aim of this study was to establish the incidence, risk factors, and prognostic consequences of AKI after TAVI and at 1-year follow-up in a single center. ⋯ Acute kidney injury occurred in 12.3% of the patients after TAVI and persisted in only one patient before hospital discharge. Diabetes and preoperative creatinine level were found to be the main predictive factors of AKI after TAVI. Acute kidney injury was not associated with increased 1-year mortality.
