Effect of physiotherapy on infertility treatment in polycystic ovary syndrome patients.

Introduction: Polycystic ovary syndrome (PCOS) is a complex hormonal condition associated with psychological, reproductive, and metabolic features. Low-grade inflammation is a recognised factor causing metabolic and reproductive disorders in PCOS, which is why anti-inflammation approaches in PCOS treatment, especially during the COVID pandemic, are considered. A promising therapeutic option is osteopathic manipulative treatment (OMT), which activates the cholinergic anti-inflammatory pathway and can inhibit proinflammatory cytokines, such as TNF, IL-1ß, and TNF-ß. In our paper we analysed the influence of OMT in women with PCOS. Material and methods: Seventy-three patients, aged 29-46 years, with a history of reproductive failure, who underwent a physiotherapeutic treatment were evaluated. Six months after the end of a physiotherapy session, a follow-up questionnaire was performed. Results: The results show that most women (83.6%) were satisfied with the therapeutic process, and that the sessions met the patient's expectations. Reducing the level of anxiety related to infertility treatment and pregnancy was declared by 60 (82.2%) women, an improvement in well-being was declared by 72 (97.3%) (p = 0.04), and increasing awareness of the body after physiotherapy sessions was declared by 70 (95.9%) women. Conclusions: The physiotherapeutic sessions improved infertility treatment, enhanced quality of life, and had a positive effect on overall health in PCOS women.

Extracellular Vesicles to Predict Outcomes After Transcatheter Aortic Valve Implantation - a Prospective, Multicenter Cohort Study.

INTRODUCTION: Transcatheter aortic valve implantation (TAVI) is an established treatment for aortic stenosis (AS) in patients at intermediate and high surgical risk. Circulating extracellular vesicles (EVs) are nanoparticles involved in cardiovascular diseases. We aimed to (i) determine the effect of TAVI on plasma concentrations of five EV subtypes and (ii) evaluate the predictive value of EVs for post-TAVI outcomes. METHODS: Blood samples were collected 1 day before TAVI and at hospital discharge. Concentrations of EVs were evaluated using flow cytometry. RESULTS: Concentration of leukocytes EVs decreased after TAVI, compared to the measurement before (p = 0.008). Among 123 patients discharged from the hospital, 19.5% experienced MACCE during the median of 10.3 months. Increased pre-TAVI concentration of phosphatidylserine-exposing EVs was an independent predictor of MACCE in multivariable analysis (OR 5.313, 95% CI 1.164-24.258, p = 0.031). CONCLUSIONS: Patients with increased pre-TAVI concentration of procoagulant, PS-exposing EVs have over fivefold higher odds of adverse outcomes.

Valve-in-valve transcatheter transfemoral mitral valve implantation (ViV-TMVI): Characteristics and early results from nationwide registry.

BACKGROUND: Valve-in-valve transcatheter transfemoral mitral valve implantation (ViV-TMVI) is an emerging treatment alternative to reoperation in high surgical risk patients with a failed mitral bioprostheses. AIM: To describe characteristics and evaluate 30-day outcomes of ViV-TMVI in the Polish population. METHODS: Nationwide registry was initiated to collect data of all patients with failed mitral bioprosthesis undergoing ViV-TMVI in Poland. This study presents 30-days clinical and echocardiographic follow-up. RESULTS: Overall, 27 ViV-TMVI were performed in 8 centers until May 2022 (85% since 2020). Mean (standard deviation [SD]) age was 73 (11.6) years with the median (interquartile range [IQR]) STS score of 5.3% (4.3%-14.3%). Mean (SD) time between surgical implantation and ViV-TMVI was 8.2 (3.2) years. Failed Hancock II (29%) and Perimount Magna (22%) were most frequently treated. Mechanisms of failure were equally often pure mitral regurgitation or stenosis (both 37%) with mixed etiology in 26%. Balloon-expandable Sapien 3/Ultra were used in all but 1 patient. Technical success was 96.3% (1 patient required additional prosthesis). Mean (SD) transvalvular mitral gradient reached 6.7 (2.2) mm Hg and mitral valve area was 1.8 (0.4) cm². None of the patients had moderate or severe mitral regurgitation with only 14.8% graded as mild. In 92.6% device success (2 patients had mean gradient ≥10 mm Hg) and in 85.6% procedural success was present. There were no deaths, cerebrovascular events or need for mitral valve surgery during 30-day follow-up. CONCLUSIONS: In short-term observation ViV-TMVI is safe and effective alternative for patients with failed mitral bioprosthesis at high surgical risk of re-operation. Longer observations on larger sample are warranted.

Transcatheter aortic valve­in­valve implantation for failed surgical bioprostheses: results from the Polish Transcatheter Aortic Valve-in-Valve Implantation (ViV­TAVI) Registry

INTRODUCTION: Transcatheter aortic valve­in ­valve implantation (ViV­TAVI) has emerged as an alternative to redo surgery in patients with failed surgical aortic bioprosthesis. OBJECTIVES: We evaluated the safety and efficacy of ViV­TAVI in Polish patients after surgical aortic valve replacement. PATIENTS AND METHODS: This was a nationwide multicenter registry of ViV­TAVI procedures. Data were collected using an online form, and the clinical follow ­up lasted 1 year. RESULTS: From 2008 to 2020, 130 ViV­TAVI procedures were performed (1.9% of all transcatheter aortic valve implantation [TAVI] cases). A considerable increase in ViV­TAVI procedures since 2018 has been observed (n = 59, 45% of ViV­TAVI cases). Hancock II, Freestyle, and homograft were the most frequently treated bioprostheses. The self ­expanding supra ­annular Corevalve / Evolut valve was used in 76% of cases. In 21% of cases, the mean postprocedural pressure gradient (PG) exceeded 20 mm Hg. All­cause mortal­ity at 1 year was 10.8%. Aortic valve stenosis was associated with a higher mean PG than aortic valve regurgitation or mixed disease (P = 0.004). Supra ­annular transcatheter aortic valves were associated with lower mean PGs than intra ­annular valves (P = 0.004). Second ­generation devices were associated with shorter procedure time (120 min vs 135 min, P = 0.04), less frequent need for additional TAVI (2% vs 10%, P = 0.04), and lower 1­year cardiovascular mortality (95% vs 82.8%, P = 0.03) than first­generation valves. CONCLUSIONS: Transcatheter treatment of failed bioprostheses is increasingly common, with the best hemodynamic effect shown for supra ­annular valves. The introduction of second­generation valves has improved procedural and clinical outcomes.

Temporal trends of transcatheter aortic valve implantation in a high-volume academic center over 10 years.

BACKGROUND: Indications for transcatheter aortic valve implantation (TAVI) have gradually expanded since its introduction. AIMS: The aim was to analyze temporal trends in TAVI characteristics based on the experience of a high-volume academic center over the period of 10 years. METHODS: Five hundred and six consecutive (n = 506) patients with 1-year follow-up were divided into early (G1, years 2010-2013, n = 130), intermediate (G2, 2014-2016, n = 164) and recent (G3, 2017-2019, n = 212) experience groups. RESULTS: Patient's age remained constant over time (mean [SD]; G1 = 79.1 [7.1] years vs G2 = 79.1 [7.1] years vs G3 = 79.7 [6.6] years, P = 0.73) but surgical risk in G3 was lower (log Euroscore, median [IQR]: G1 = 14.0 [8.4-20.2] vs G2 = 12.0 [7.0-22.2] vs G3 = 5.1 [3.5-8.5]; P <0.001). Major/life-threatening bleeding (G1 = 26.9% vs G2 = 12.8% vs G3 = 9.4%; P <0.001), major vascular complications (G1 = 15.4% vs G2 = 8.5% vs G3 = 5.7%; P = 0.02) and moderate/severe paravalvular leak (G1 = 16.2% vs G2 = 11% vs G3 = 7.5%; P = 0.046) were decreasing with time. There was a significant drop in all-cause 1-year mortality in G3 (G1 = 20% vs G2 = 17.7% vs G3 = 9.1%; log rank = 0.01). CONCLUSIONS: The age of TAVI recipients remained unchanged over the last decade. Decreasing surgical risk coupled with improvements in procedural technique and care resulted in fewer periprocedural complications and better 1-year survival.

Non-calcific aortic tissue quantified from computed tomography angiography improves diagnosis and prognostication of patients referred for transcatheter aortic valve implantation.

AIMS: We aimed to investigate the role of aortic valve tissue composition from quantitative cardiac computed tomography angiography (CTA) in patients with severe aortic stenosis (AS) for the differentiation of disease subtypes and prognostication after transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS: Our study included 447 consecutive AS patients from six high-volume centres reporting to a prospective nationwide registry of TAVI procedures (POL-TAVI), who underwent cardiac CTA before TAVI, and 224 matched controls with normal aortic valves. Components of aortic valve tissue were identified using semi-automated software as calcific and non-calcific. Volumes of each tissue component and composition [(tissue component volume/total tissue volume) × 100%] were quantified. Relationship of aortic valve composition with clinical outcomes post-TAVI was evaluated using Valve Academic Research Consortium (VARC)-2 definitions.High-gradient (HG) AS patients had significantly higher aortic tissue volume compared to low-flow low-gradient (LFLG)-AS (1672.7 vs. 1395.3 mm3, P < 0.001) as well as controls (509.9 mm3, P < 0.001), but increased non-calcific tissue was observed in LFLG compared to HG patients (1063.6 vs. 860.2 mm3, P < 0.001). Predictive value of aortic valve calcium score [area under the curve (AUC) 0.989, 95% confidence interval (CI): 0.981-0.996] for severe AS was improved after addition of non-calcific tissue volume (AUC 0.995, 95% CI: 0.991-0.999, P = 0.011). In the multivariable analysis of clinical and quantitative computed tomography parameters of aortic valve tissue, non-calcific tissue volume [odds ratio (OR) 5.2, 95% CI 1.8-15.4, P = 0.003] and history of stroke (OR 2.6, 95% CI 1.1-6.5, P = 0.037) were independent predictors of 30-day major adverse cardiovascular event (MACE). CONCLUSION: Quantitative CTA assessment of aortic valve tissue volume and composition can improve detection of severe AS, differentiation between HG and LFLG-AS in patients referred for TAVI as well as prediction of 30-day MACEs post-TAVI, over the current clinical standard.

Predictors and Biomarkers of Subclinical Leaflet Thrombosis after Transcatheter Aortic Valve Implantation.

Transcatheter aortic valve implantation (TAVI) is a recent revolutionary treatment for high-risk patients with severe aortic stenosis who are not suitable for surgery, expanding to intermediate and low-risk patients. Valve leaflet thrombosis (LT) is a potentially fatal complication after TAVI. The incidence of subclinical LT is as high as 25% among patients in the first year after TAVI. Subclinical LT may evolve into symptomatic thrombosis or lead to premature bioprosthesis degeneration, increasing the risk of neurological complications. Because imaging-based methods have limited sensitivity to detect subclinical LT, there is an urgent need for predictors and biomarkers that would make it possible to predict LT after TAVI. Here, we summarize recent data regarding (i) patient-related, (ii) procedure-related, (iii) blood-based and (iv) imaging predictors and biomarkers which might be useful for the early diagnosis of subclinical LT after TAVI. Prevention of LT might offer an opportunity to improve risk stratification and tailor therapy after TAVI.

Use of protamine sulfate during transfemoral transcatheter aortic valve implantation - a preliminary assessment of administration rate and impact on complications.

INTRODUCTION: Bleeding complications after transcatheter aortic valve implantation (TAVI) are an important issue and negatively affect survival. The rate and impact of protamine sulfate (PS) administration on bleeding complications after TAVI remain unclear. AIM: To assess the impact of PS on bleeding complications after TAVI. MATERIAL AND METHODS: Between March 2010 and November 2016 two hundred fifty-eight patients qualified for TAVI in one academic center were screened. Baseline, procedural and follow-up data up to 30 days were collected and analyzed. The primary endpoint (PE) was major bleeding according to the Valve Academic Research Consortium up to 48 h after the procedure. RESULTS: Overall, 186 patients (96 females, mean age: 80 years) met the inclusion criteria. Thirty-nine (21%) subjects received PS. PE occurred in 24.7% of the study population. There were no significant differences in terms of the PE rate between the groups (25.6% in the PS group and 24.7% in the remaining cohort, p = 0.9, odds ratio (OR) = 1.05, confidence interval (CI): 0.47-2.4, p = 0.9). Multivariate analysis identified female gender (OR = 2.2, CI: 1.08-4.4, p = 0.03) as an independent predictor of PE occurrence. Similarly, female gender (OR = 2, CI: 1.06-3.84, p = 0.03) as well as general anesthesia (GA, OR = 2.23, CI: 1.13-4.63, p = 0.02) and dose of unfractionated heparin per kilogram (UFH/kg, OR = 1.02, CI: 1-1.03 per 1 IU increment, p = 0.02) predicted the occurrence of a composite of major and minor bleeding. CONCLUSIONS: In this analysis, PS administration did not decrease the PE rate. Female gender predicted PE occurrence. Randomized, placebo-controlled trials are required to accurately assess the impact of PS.
