This study investigates the redislocation rate and functional outcome at a minimum follow-up of five years after medial patellofemoral ligament (MPFL) reconstruction with soft tissue patellar fixation for patella instability.

Patients were retrospectively identified and knees were evaluated for trochlea dysplasia according to Dejour, for presence of patella alta and for presence of cartilage lesion at surgery. At a minimum follow-up of five years, information about an incident of redislocation was obtained. Kujala, Lysholm, and Tegner questionnaires as well as range of motion were used to measure functional outcome.

Eighty-nine knees were included. Follow-up rate for redislocation was 79.8% and for functional outcome 58.4%. After a mean follow-up of 5.8 years, the redislocation rate was 5.6%. There was significant improvement of the Kujala score (68.8 to 88.2, p = 0.000) and of the Lysholm score (71.3 to 88.4, p = 0.000). Range of motion at follow-up was 149.0° (115-165). 77.5% of the knees had patella alta and 52.9% trochlear dysplasia types B, C, or D. Patellar cartilage legions were present in 54.2%. Redislocations occurred in knees with trochlear dysplasia type C in combination with patella alta.

MPFL reconstruction with soft tissue patellar fixation leads to significant improvement of knee function and low midterm redislocation rate. Patients with high-grade trochlear dysplasia should be considered for additional osseous correction.

Echocardiography determined LAA peak outflow and inflow velocities and intracardiac catheter-based mean LAA and RAA AF cycle length (AFCL) were obtained during AF before ablation. The impact of flow velocities and AFCL on the prevalence and location of LVA was further evaluated. LVA were detected in 54% of the patients. 14% of the patients presented severe global LVA burden > 20% of the total LA surface area. 29% of the patients presented a disseminated pattern of remodelling as 3 out of 5 LA segments were affected. LAA AFCL, RAA AFCL, LAA flow velocities did not predict the absolute presence of LVA. However LAA AFCL > 155 ms predicted disseminated LVA pattern and LAA AFCL > 165 ms severe LVA incidence. LAA AFCL > 155 ms was predictive for existence of LVA within antero-septal LA segments whilst LAA emptying velocity ≤ 0.2 m/s within lateral wall. Moreover RAA AFCL > 165 ms was strongly related to the presence of LAA AFCL > 15 ms and > 165 ms. LAA and RAA functional assessment was predictive of the presence of advanced stages of voltage-defined LA fibrosis and its regional distribution among LSPAF population.Transcatheter atrial septal defect (ASD) closures using an Amplatzer Septal Occluder (ASO) have been widely performed. Compared to children, we sometimes experience late recovery of exercise performance in adult patients. Our study aimed to evaluate the change in the cardiopulmonary exercise capacity in asymptomatic or mildly symptomatic adult patients after a transcatheter ASD closure using an ASO. The subjects consisted of 29 patients (age 39.5 ± 13.6 years) that underwent cardiopulmonary exercise testing (CPX) before, 3, 6, and 12 months after a transcatheter secundum ASD closure using an ASO. The peak oxygen consumption (peak VO2), anaerobic threshold (AT), and slope of the correlation between the ventilation and carbon dioxide production (VE/VCO2 slope) were evaluated. see more We also evaluated the left-ventricular end-diastolic diameter (LVEDD), right-ventricular end-diastolic dimension (RVEDD) by echocardiography, and hemodynamic values by cardiac catheterization before the ASO procedure. The peak VO2 did not show any improvement 3 months after the ASO procedure; however, a significant improvement was displayed 6 and 12 months (baseline 23.4 ± 6.3, 3 months 23.6 ± 6.4, 6 months 25.1 ± 5.6, 12 months 26.4 ± 5.3 mL/kg/min; p  less then  0.001) after the ASO. The LVEDD (before 38.1 ± 3.6, 3 months 43.4 ± 3.4 mm; p  less then  0.001) and RVEDD (before 33.6 ± 5.3, 3 months 26.3 ± 2.6 mm; p  less then  0.001) on echocardiography quickly improved 3 months after the ASO. Although the LVEDD and RVEDD normalized 3 months after the ASO, the peak VO2 still decreased; however, the peak VO2 improved to almost a normal range 6 months after the ASO.Recently, Society for Vascular Surgery guideline recommends evaluating anatomic pattern with use of Global Limb Anatomic Staging System (GLASS) in Chronic Limb-Threatening Ischemia (CLTI) patients. The aim of this study is to validate GLASS stage into CLTI patients on hemodialysis (HD) and investigate the impact of GLASS stage to wound healing and amputation-free survival (AFS). Between April 2009 and March 2018, we performed EVT for 154 limbs in CLTI patients on HD. GLASS was defined as femoropopliteal (FP) and infrapopliteal (IP) segments separately graded (0-4), then combined into three GLASS stages for the limb (I-III). We divided them into three GLASS stages with using this system. We compared the clinical outcomes between three groups (GLASS I, GLASS II, and GLASS III). Patient characteristics were almost similar between the three groups. Lesion characteristics was more complex and the rate of success was lower in GLASS III. Cox regression multivariate analysis revealed that diabetes mellitus (HR 2.4, 95% CI 1.37-4.01, p  less then  0.01) and WIfI high (HR 2.3, 95% CI 1.04-6.01, p = 0.04) were the predictors of non-wound healing, whereas age (HR 1.6, 95% CI 1.09-2.29, p = 0.01), WIfI clinical stage 4 (HR 2.4, 95% CI 1.30-4.36, p  less then  0.01), and non-ambulatory status (HR 2.0, 95% CI 1.17-3.29, p = 0.01) were the predictors of AFS. GLASS stage in CLTI patient on HD could not predict wound healing, and AFS in this study.
