Clinical TrialMeasurement of preoperative lobar lung function with computed tomography ventilation imaging: progress towards rapid stratification of lung cancer lobectomy patients with abnormal lung function.
In lung cancer preoperative evaluation, functional lung imaging is commonly used to assess lobar function. Computed tomography ventilation (CT-V) imaging is an emerging lung function imaging modality. We compared CT-V imaging assessment of lobar function and its prediction of postoperative lung function to that achieved by (i) positron emission tomography ventilation (PET-V) imaging and (ii) the standard anatomical segment counting (ASC) method. We hypothesized (i) that CT-V and PET-V have similar relative lobar function and (ii) that functional imaging and anatomic assessment (ASC) yield different predicted postoperative (ppo) lung function and therefore could change clinical management. ⋯ The assessment of lobar function from CT-V imaging correlated strongly with PET-V imaging, but had low correlations with ASC. CT-V imaging may be a useful alternative method in preoperative evaluation for lung cancer patients.

Propensity score-matching analysis of hybrid video-assisted thoracoscopic surgery and thoracoscopic lobectomy for clinical stage I lung cancer†.
Video-assisted thoracoscopic surgery (VATS) lobectomy is classified into hybrid VATS (direct and video vision) and thoracoscopic VATS (video vision only). In this study, the outcomes of hybrid VATS and thoracoscopic VATS for clinical stage I lung cancer were compared using a propensity score-matching analysis. ⋯ In this single-institution, propensity score-matched study, hybrid VATS showed a shorter operative time and similar outcomes compared with thoracoscopic lobectomy for clinical stage IA lung cancer.

Decellularized aortic allografts versus pulmonary autografts for aortic valve replacement in the growing sheep model: haemodynamic and morphological results at 20 months after implantation.
Pulmonary autografts (PAs) represent the substitute of choice for aortic valve (AV) replacement, especially in children and young adults. Similarly, decellularized aortic valve allografts (DAVAs) have shown excellent mid-term function when implanted in the systemic circulation. The aim of this study was to compare the performance of DAVAs with that of pulmonary autografts after a Ross procedure in the growing sheep model. ⋯ DAVAs and PAs provide adequate haemodynamics after AV replacement in the growing sheep. While decellularized grafts are repopulated by endothelial and interstitial cells, autografts maintain in general their native cell distribution. Maintenance of valvular competence during enlargement of the valve ring is, in our opinion, representative of the capacity for physiological growth in both graft types.

Mid-term haemodynamic and clinical results after aortic valve replacement using the Freedom Solo stentless bioprosthesis versus the Carpentier Edwards Perimount stented bioprosthesis.
The aim of this study was to investigate the mid-term haemodynamic and clinical results after aortic valve replacement (AVR) using the Sorin Freedom Solo (SFS) stentless bioprosthesis, compared with the standard Carpentier Edwards Perimount (CEP) stented bioprosthesis. ⋯ These data suggest that the Sorin Freedom Solo stentless bioprosthesis is as safe as the Carpentier Edwards bioprosthesis, and provides better short- and mid-term haemodynamic performance than the Carpentier Edwards bioprosthesis.

The fate of mild-to-moderate proximal aortic dilatation after isolated aortic valve replacement for bicuspid aortic valve stenosis: a magnetic resonance imaging follow-up study†.
The treatment of mild-to-moderate aortic dilatation at the time of aortic valve replacement (AVR) in patients with bicuspid aortic valve (BAV) disease is still controversial. We aimed to estimate late progression of aortopathy in patients who underwent isolated AVR for BAV stenosis with concomitant proximal aortic dilatation of ≥40 mm. ⋯ Mild-to-moderate ascending aortic dilatation remains stable in most BAV patients who underwent isolated AVR surgery for aortic valve stenosis at least 10-year post-AVR.
