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.

Multicenter StudyThe importance of intraoperative fluid balance for the prevention of postoperative acute exacerbation of idiopathic pulmonary fibrosis after pulmonary resection for primary lung cancer.
Postoperative acute exacerbation (PAE) of idiopathic pulmonary fibrosis (IPF) is a serious complication that is hard to treat. Therefore, it is important to manage IPF patients in such a way as to avoid PAE. Conversely, the relationship between postoperative acute lung injury and perioperative fluid administration has been reported. Herein, we analyse the perioperative risk factors of PAE of IPF, including fluid management. ⋯ To prevent PAE of IPF, intraoperative management that minimizes intravenous fluid administration is essential. Moreover, caution is particularly important in patients with preoperative evidence of inflammation.

Assessment of aortopulmonary collateral flow and pulmonary vascular growth using a 3.0 T magnetic resonance imaging system in patients who underwent bidirectional Glenn shunting.
To explore the feasibility of evaluating the aortopulmonary collateral flow (APCF) and pulmonary vascular growth of patients who underwent bidirectional Glenn shunting (BGS) using phase-contrast magnetic resonance imaging (PC-MRI) and contrast-enhanced magnetic resonance imaging (CE-MRI). ⋯ Assessing the APCF and parameters for pulmonary vascular growth in patients who underwent BGS is feasible using 3.0 T PC-MRI integrated with CE-MRI, which may play an important role in clinical and therapeutic decision-making and prognostic evaluation.

Multicenter StudyTwinned single-lung transplantation: a privileged model for the study of recipient-dependent factors of outcome.
Lung transplantation is the only life-saving treatment for end-stage respiratory disease. The outcome will depend on the graft quality, surgical conditions and recipient factors. Twinned single-lung transplantation defines as two different recipients treated with lung grafts from the same donor. Recipient-dependent factors of the outcome can be studied more accurately as the graft quality is supposed equal for both recipients. ⋯ We conclude that recipient's disease is a major determinant of the outcome. Fibrosis is associated with an increased risk for PGD.

Controlled Clinical TrialTotally thoracoscopic closure for atrial septal defect on perfused beating hearts.
To investigate the feasibility and safety of non-robotically assisted totally thoracoscopic closure for atrial septal defect (ASD) on perfused beating hearts. ⋯ Non-robotically assisted totally thoracoscopic closures of ASD on perfused beating hearts are feasible and safe. These procedures are associated with a shorter operation time and a shorter hospital stay than in surgeries on cardioplegic arrested hearts.
