Multicenter StudyEffects of low-dose human atrial natriuretic peptide for preventing post-operative cardiopulmonary complications in elderly patients undergoing pulmonary resection for lung cancer.
The objective of the present study was to evaluate the clinical effects of human atrial natriuretic peptide (hANP) on post-operative cardiopulmonary complications in elderly patients undergoing pulmonary resection for lung cancer. ⋯ Continuous infusion of low-dose hANP during lung cancer surgery had a prophylactic effect on post-operative cardiopulmonary complications in elderly lung cancer patients.

Reparative surgery of the pulmonary autograft: experience with Ross reoperations.
Autograft valve and root pathology is the leading cause of Ross procedure failure. To define risk and outcome of autograft valve/root repair at reoperation, a 17-year experience was analysed. ⋯ Autograft reoperation carries negligible hospital risk. Pulmonary valve sparing or repair is feasible in half of patients with Ross failure. Concomitant root remodelling and absence of preoperative severe valve dysfunction predict successful and durable repair.

Aortic valve calcium scoring is a predictor of significant paravalvular aortic insufficiency in transapical-aortic valve implantation.
Transapical-aortic valve implantation (TA-AVI) has evolved as routine for selected high-risk patients. However, paravalvular leaks >1+ remain an unsolved issue using current generations of transcatheter valve devices. The purpose of this study was to investigate the impact of native aortic valve calcification on paravalvular leaks and outcomes using the Edwards SAPIEN™ prosthesis. ⋯ Severe native valve calcifications are predictive for postoperative relevant paravalvular leak. AVCS prior to TA-AVI might serve as an additional tool to reconsider the TAVI indication to reduce the risk of paravalvular leaks especially in so-called operable patients.

Multicenter Study Clinical TrialTransapical transcatheter aortic valve implantation using the JenaValve™ system: acute and 30-day results of the multicentre CE-mark study.
Transcatheter aortic valve implantation (TAVI) has shown promising results in patients with severe aortic stenosis (AS) at high risk for conventional heart surgery. The safety and efficacy of transapical aortic valve implantation using the JenaValve™, a second-generation TAVI device, were evaluated. The system consists of a tested porcine root valve mounted on a nitinol stent with feeler-guided positioning and clip fixation on the diseased leaflets. ⋯ Transapical JenaValve™ implantation was safe and effective in the treatment of severe AS in elderly patients at high risk for surgery. Active clip fixation on the native leaflets and anatomically correct feeler-guided positioning led to good functionality and prevented ostial coronary impairment. Implantation without the need for rapid pacing prevented haemodynamic compromise during valve implantation.

Comparative StudyMediastinal lymph node dissection in early-stage non-small cell lung cancer: totally thoracoscopic vs thoracotomy.
Although major pulmonary resections for early-stage non-small cell lung cancer (NSCLC) are more and more frequently performed through thoracoscopy, the adequacy of lymphadenectomy achieved via this approach is still questioned. The aim of this study was to evaluate the results of lymph node dissection (LND) during totally thoracoscopic (TT) major pulmonary resections. ⋯ For patients undergoing thoracoscopic lobectomy or segmentectomy for clinical early-stage NSCLC, the quality of mediastinal LND is equivalent to that performed by thoracotomy.
