Multicenter Study Comparative Study
Transapical versus transfemoral aortic valve implantation: a multicenter collaborative study.
There are no direct comparisons between transapical aortic valve implantation (TA-AVI) and transfemoral aortic valve implantation (TF-AVI). Therefore, the aim of this study was to compare the short-term and midterm outcomes of TA-AVI versus TF-AVI. ⋯ In institutions performing a low volume of TA-AVI, the technique is associated with an increased risk of all-cause mortality and longer hospital stay but less vascular complications in comparison with TF-AVI. The interaction between experience and type of treatment on outcome requires further investigation before advocating one treatment over the other.

Comparative Study
Optimal timing of thoracoscopic drainage and decortication for empyema.
Although video-assisted thoracic surgery (VATS) pleural drainage and decortication have been proven to be effective treatments in the early stages of empyema, the optimal timing of VATS is still not clear. To assess the effectiveness of early VATS drainage and decortication, we reviewed the records of patients who underwent VATS and open decortication for empyema. ⋯ Patients with symptom durations of less than 4 weeks showed better early results than those with symptom durations greater than 4 weeks. Thus, symptom duration can be considered a reliable preoperative factor in deciding the surgical management of empyema or cases involving loculated pleural effusion.

Comparative Study
Quo vadis pulmonary autograft--the ross procedure in its second decade: a single-center experience in 645 patients.
The enthusiasm about the advantages of a viable autologous transplant faded with recent reports of autograft deterioration and associated reoperations after the Ross procedure. This report evaluates predictors for autograft failure and outcomes extending into the second decade after a Ross procedure. ⋯ In this large series, the Ross procedure resulted in excellent long-term survival rates with a low risk of valve-related morbidity and a considerably low rate of reoperations in young and middle-aged patients and should be considered as an important treatment option in this cohort.

This study compared surgical outcomes of patients with previous cardiac surgery undergoing transapical transcatheter aortic valve implantation (PCS-TA-TAVI) with those of patients undergoing transapical transcatheter aortic valve implantation as an initial procedure (initial TA-TAVI) by using propensity analysis. ⋯ Transapical transcatheter aortic valve implantation has simplified surgical treatment of high-risk patients with previous cardiac surgery and severe aortic valve stenosis and is associated with minimal risk of stroke. Furthermore, current data suggest that the presence of previous cardiac surgery does not impair outcomes after transapical transcatheter aortic valve implantation, making this subset of patients particularly applicable for this evolving approach.

Comparative Study
Video-assisted thoracic surgery for pulmonary aspergilloma: a safe and effective procedure.
A variety of complications occur in patients with pulmonary aspergilloma. The safety and feasibility of a thoracoscopic approach to therapeutic lung resection for pulmonary aspergilloma have not been well evaluated. ⋯ Video-assisted thoracic surgery is an alternative to open procedures in the management of pulmonary aspergilloma. Simple aspergilloma and complex aspergilloma without infiltration of the hilum are good candidates for VATS resection. Aspergilloma lesions that require a pneumonectomy are still a major challenge for VATS.
