The areas in which Stromal Vascular Fraction cells (SVFs) have been used include radiotherapy based tissue damage after mastectomy, breast augmentation, calvarial defects, Crohn’s fistulas, and damaged skeletal muscle. Currently, the authors present their experience using regenerative cell therapy in breast reconstruction. The goal of this study was to evaluate the safety and efficacy of the use of Engineered Fat Graft Enhanced with Adipose-derived Stromal Vascular Fraction cells (EF-e-A) in breast reconstruction. 121 patients that were affected by the outcomes of breast oncoplastic surgery were treated with EF-e-A, comparing the results with the control group (n = 50) treated with not enhanced fat graft (EF-ne-A). The preoperative evaluation included a complete clinical examination, a photographic assessment, biopsy, magnetic resonance (MRI) of the soft tissue, and ultrasound (US). Postoperative follow-up took place at two, seven, 15, 21, 36 weeks, and then annually. In 72.8% (n = 88) of breast reconstruction treated with EF-e-A, we observed a restoration of the breast contour and an increase of 12.8 mm in the three-dimensional volume after 12 weeks, which was only observed in 27.3% (n = 33) of patients in the control group that was treated with EF-ne-A. Transplanted fat tissue reabsorption was analyzed with instrumental MRI and US. Volumetric persistence in the study group was higher (70.8%) than that in the control group (41.4%) (p < 0.0001 vs. control group). The use of EF-e-A was safe and effective in this series of treated cases.

Conventional 2DSTE is a useful tool for assessing left and right heart morphology and myocardial deformation in patients with OSAS and for monitoring both acute and chronic effects of NIV.

Impaired RV diastolic and systolic myocardial function were present even in IPF patients without PH, which indicates an early impact on RV function and structure in patients with IPF.

Aims Transcatheter aortic valve implantation (TAVI) is an alternative treatment in surgically high‐risk or inoperable patients with severe aortic stenosis (AS). The objective of this study was to analyze the effects of TAVI on left ventricular (LV) and left atrial (LA) longitudinal function assessed by speckle tracking echocardiography (2DSTE) in patients with AS. Methods In our prospectively conducted study, a total of 55 symptomatic (New York Heart Association class II or higher) patients with severe AS, considered to be at increased risk for undergoing surgical aortic valve replacement, were recruited (age: 78.6 ± 7.4 year). Patients underwent a complete clinical and laboratory evaluation, in addition to standard echocardiography and 2DSTE. Echocardiographic analysis was performed before and 6 months after TAVI. 2DSTE measured segmental and global longitudinal strain (GLS) and radial strain. Results All the patients received the CoreValve self‐expanding prosthesis. Six months after TAVI, patients showed a significant reduction in mean transaortic gradient (52.1 ± 15.8 vs. 11.2 ± 3.3 mmHg, P < 0.0001), LV mass, LA volume index, and an improvement of ejection fraction (P < 0.0001). In addition, LV GLS (−11.8 ± 3.2 vs. −16.3 ± 4.2%; P < 0.0001) and LA longitudinal strain (14.2 ± 5.4 vs. 26.6 ± 10.8%, P < 0.0001) significantly increased after TAVI. In a stepwise forward multiple logistic regression analysis, LV mass before TAVI (P < 0.001) and peak CK MB mass after TAVI (P < 0.0001) were powerful independent predictors of lower improvement of LV GLS. Moreover, LV mass index (P < 0.001) and LV GLS strain (P < 0.001) before TAVI were powerful independent predictor of LA longitudinal strain after TAVI Conclusions TAVI in patients with AS resulted in geometric changes known as “reverse remodelling,” and improved LV and LA function assessed by 2DSTE.
