Thrombus in the left atrial appendage in patients with atrial fibrillation treated with non-vitamin K antagonist oral anticoagulants in clinical practice-A multicenter registry.

BACKGROUND: The prevalence and predictors of left atrial appendage thrombus (LAAT) in patients with non-valvular atrial fibrillation (AF) who have been treated with non-vitamin K antagonist oral anticoagulants (NOACs) are not well defined. We aimed to assess the occurrence and predictors of LAAT on transesophageal echocardiography (TOE) in patients with non-valvular AF treated with NOACs for at least 3 weeks. METHODS: Consecutive patients with non-valvular AF who underwent TOE before catheter ablation or electrical cardioversion in three high-reference centers between 2014 and 2018 were included. Patients on apixaban were excluded from the study due to low numbers in this category. All patients received NOACs for at least 3 weeks before TOE. RESULTS: A total of 1148 patients (female, 38.1%; mean age, 62.1 years) referred to our centers for catheter ablation of AF (52.1%) or electrical cardioversion (47.9%) were included. Patients were on rivaroxaban (51.9%) or dabigatran (48.1%). Preprocedural TOE revealed LAAT in 4.4% of all patients. Multivariable logistic regression analysis showed the CHA2DS2-VASc score ≥2 points (OR = 2.11; 95% CI, 1.15-3.88; P = .0161), non-paroxysmal AF (OR = 6.30; 95% CI, 2.22-17.91; P = .0005), and GFR <60 mL/min/1.73 m2 (OR = 2.05; 95% CI, 1.14-3.67; P = .0160) were independent predictors of LAAT in patients treated with NOACs. CONCLUSIONS: In non-valvular AF patients treated with NOACs, the prevalence of LAAT was 4.4% before electrical cardioversion or ablation. In addition to the CHA2DS2-VASc score, the type of AF and renal function should be considered in the stratification of thromboembolism risk in AF patients and qualification for a preprocedural TOE.

Decreased left atrial appendage emptying velocity as a link between atrial fibrillation type, heart failure and older age and the risk of left atrial thrombus in atrial fibrillation.

INTRODUCTION: Decreased left atrial appendage emptying velocity (LAAV) is a known predictor of LAA thrombus in atrial fibrillation (AF). The aim of our study was to identify which of the clinical risk factors for LAA thrombus are associated with decreased LAAV. METHODS: The study included 1476 consecutive AF patients who underwent transesophageal echocardiography (TEE) before AF direct current cardioversion or ablation in two high-reference cardiology departments. Patients were divided into two groups: 71 (4.8%) patients with LAAV < 20 cm/s and 1405 patients (95%) with LAAV ≥ 20 cm/s. RESULTS: Compared with patients with LAAV ≥ 20 cm/s, those with decreased LAAV were older, more often had non-paroxysmal AF, were burdened with more concomitant diseases (including hypertension, diabetes, vascular disease, and heart failure [HF]) with higher median CHA2 DS2 -VASc score (3 [2-4] vs 2 [1-3], P < .0001), and had lower glomerular filtration rate (GFR). Prevalence of LAA thrombus was higher in patients with decreased LAAV compared with those with LAAV ≥ 20cm/s (20% vs 4.6%, P < .0001). In patients with decreased LAAV, there was no difference in the frequency of LAA thrombus between those treated with VKA and those receiving NOAC, while in patients with LAAV ≥ 20 cm/s a trend was observed towards a benefit with NOAC. In multivariate logistic regression, non-paroxysmal AF, HF and age ≥ 65 years predicted both LAAV < 20 cm/s and LAA thrombus, while GFR < 60 mL/min/1.73 m2 predicted only the presence of LAA thrombus. CONCLUSION: One in five AF patients with decreased LAAV had LAA thrombus, regardless of the type of OAC. Non-paroxysmal AF, HF and age ≥ 65 years might increase LAA thrombus risk via reduced LAAV.

Pre-procedural abnormal function of von Willebrand Factor is predictive of bleeding after surgical but not transcatheter aortic valve replacement.

Both transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) have been proven to effectively correct von Willebrand Factor (vWF) pathologies, however there is limited data simultaneously comparing outcomes of both approaches. We prospectively enrolled patients with severe aortic stenosis referred for TAVI (n = 52) or SAVR (n = 48). In each case, vWF antigen (vWF:Ag), vWF activity (vWF:Ac) and activity-to-antigen (vWF:Ac/Ag) ratio were assessed at baseline, 24 h and 72 h after procedure. VWF abnormalities were defined as reduced vWF:Ac/Ag ratio (< 0.8). Bleeding events in both arms were classified according to Valve Academic Research Consortium (VARC-2) definitions. Overall, there was no difference between patients referred for TAVI and SAVR in vWF:Ac (1.62 ± 0.52 vs 1.71 ± 0.64; p = 0.593), vWF:Ag (1.99 ± 0.81 vs 2.04 ± 0.81; p = 0.942) or vWF:Ac/Ag ratio (0.84 ± 0.16 vs 0.85 ± 0.12; p = 0.950). Pathological vWF:Ac/Ag ratio was found in 20 (38%) TAVI and 15 (31%) SAVR patients (p = 0.407). Normalization of vWF:Ac/Ag ratio at day 3 after procedure was achieved in 19 (95%) TAVI and 13 (87%) SAVR patients (p = 0.439). Similar prevalence of major or life-threatening bleedings (MLTB) after TAVI and SAVR in entire groups was observed (19% vs. 23%, p = 0.652). VWF abnormalities were associated with higher incidence of MLTB in SAVR (53% vs 9%, p < 0.001), but not TAVI (15% vs. 22%, p = 0.132). Accordingly, in receiver-operating characteristic curve analysis vWF:Ac/Ag ratio < 0.8 showed significant sensitivity and specificity for predicting MLTB in SAVR group (AUC 0.735, 95% CI 0.538-0.931, p = 0.019). We proved that abnormal function of vWF is corrected successfully after both TAVI and SAVR, but vWF abnormalities are predictive of MLTB only in surgical patients.

Different types of endocarditis after transcatheter aortic valve implantation.

INTRODUCTION: Infective endocarditis (IE) may take different faces in patients after transcatheter aortic valve implantation (TAVI). OBJECTIVES: The primary aim of this study was to describe echocardiographic and clinical characteristics of TAVI's patients suffered from IE. METHODS: In a single-center, retrospective study we analyzed 311 consecutive patients treated with TAVI for severe aortic stenosis between 2010 and 2018. RESULTS: According to modified Duke criteria, we confirmed IE in 2.2% of the cohort, however PVE of TAVI's valve in 1.2% only; rest of the group suffered from CDRiE and IE of the mitral valve. In PVE's group vegetations were localized inside the frame with or without bioprosthesis moderate stenosis or regurgitation. Only 1 pts developed significant TAVI's bioprosthesis' paravalvular leak. We observed no native aortic anulus involvement. Mortality rate in the PVE-TAVI's group was 75% regardless of the type of treatment. CONCLUSIONS: The above findings show that IE following TAVI is a serious complication and various scenarios (also CDRiE and native valve IE) should be considered.

Concomitant coronary artery disease and its management in patients referred to transcatheter aortic valve implantation: Insights from the POL-TAVI Registry.

BACKGROUND: Coronary artery disease (CAD) and degenerative aortic stenosis often coexist. However, the impact of CAD and its management on the prognosis after transcatheter aortic valve implantation (TAVI) remains uncertain. We sought to evaluate the impact of obstructive CAD, SYNTAX score (Ss), and percutaneous coronary intervention (PCI) prior to TAVI on short-term outcome. METHODS: Overall, 896 patients who underwent TAVI after heart team decision was included. Pre-procedural angiograms were analysed to calculate baseline Ss (bSs) and residual Ss (rSs). Baseline, procedural and follow-up data up to 30 days was acquired from the national POL-TAVI registry. RESULTS: Patients with obstructive CAD at baseline (n = 462, 52%) had higher mortality as compared with the remaining (8.7 vs. 5.1%, log-rank P = 0.039). Also, after correction for confounding factors obstructive CAD was identified as independent predictor of mortality (hazard ratio [HR] 1.74, 95% confidence intervals [CIs] 1.03-2.94, P = 0.037). In obstructive CAD, neither bSs (AUC 0.47, CI 0.38-0.56, P = 0.47) nor rSs (AUC 0.47, CI 0.30-0.64, P = 0.72 for those undergoing PCI and AUC 0.48, CI 0.37-0.59, P = 0.75 for the remaining) was predictive of mortality. When revascularization status was considered, patients with PCI prior to TAVI had similar outcome as those without obstructive CAD at baseline (7.7 vs. 5.1%, log-rank P = 0.23) with no negative impact on mortality (HR 1.13, CI 0.62-2.09, P = 0.69). CONCLUSIONS: In conclusion, obstructive CAD at baseline evaluation for TAVI has independent negative impact on short-term prognosis. However, neither baseline nor residual Ss values have prognostic ability in patients undergoing TAVI. Revascularization prior to TAVI seems to improve survival to levels comparable with patients without obstructive CAD at baseline.

Transcatheter aortic valve-in-valve implantation in failed stentless bioprostheses.

OBJECTIVE: To compare the safety and efficacy of transcathether aortic valve-in-valve implantation (ViV-TAVI) in degenerated stentless bioprostheses with failed stented valves and degenerated native aortic valves. INTRODUCTION: Little is known about ViV-TAVI in degenerated stentless valves. METHODS: Out of 45 ViV-TAVI procedures reported in the POL-TAVI registry, 20 failed stentless valves were compared with 25 stented prostheses and propensity-matched with 45 native TAVI cases. The mean follow-up was 633 (95% confidence interval [CI], 471-795) days and Valve Academic Research Consortium-2 (VARC-2) definitions were applied. RESULTS: Patients with degenerated stentless valves were younger (65.6, CI 58-73.1 years vs 75.6, CI 72.2-78 [stented] vs 80.1, CI 78.7-81.6 y. [native], P < 0.001). Implantation was required later after surgery (11.5, CI 8-14.9 years) in the stentless cohort as compared with the stented one (6.2, CI 4.7-7.6 years, P = 0.006). ViV-TAVI in the stentless group was also associated with larger amount of contrast (211, CI 157-266 mL vs 135, CI 104-167 mL [stented] vs 132 (119-145) mL [native], P = 0.022). Using VARC-2 composite endpoints, ViV-TAVI in stentless prostheses was characterized by a lower device success (50% vs 76% in stented vs 88.9% in native TAVI, P < 0.001), but comparable early safety up to 30 days (73.7% vs 84% vs 81.8%, respectively, log-rank P = 0.667) and long-term clinical efficacy beyond 30 days (72.2% vs 72% vs 73.8%, respectively, log-rank P = 0.963). CONCLUSIONS: Despite technical challenges and a lower device success, ViV-TAVI in stentless aortic bioprostheses achieves similar safety, efficacy, and functional improvement as in stented or degenerated native valves.

Percutaneous Closure of Post-Infarction Ventricular Septal Defects-An Over Decade-long Experience.

OBJECTIVES: To report an over decade-long experience with percutaneous post-infarction ventricular septal defect (PIVSD) closure. BACKGROUND: PIVSDs remains a major clinical challenge with extremely high mortality. Data concerning interventional closure of PIVSD is scarce. METHODS: All percutaneous PIVSD closures performed between 2003 and 2016 in 8 participating centres were identified. Data concerning patients and procedures was acquired. Patients were divided into two groups, based on the time interval between VSD diagnosis and closure (≤14 days-acute phase, >14 days-non-acute phase). RESULTS: Twenty-one percutaneous PIVSD closures were performed on 20 patients (9 females, mean age: 70 years). Mean interval between the diagnosis and the procedure was 182.6 ± 500 days (range: 7-2228). Defects were mostly located in apical (55%) segments of the septum. In 7 cases (33%) the procedure was performed in the acute phase. The closure was technically successful in 17 cases (81%). Four patients died within 48 hours after the procedure. 30-days survival rate of the entire cohort was 70%. Univariate analysis revealed impact of technical success of the procedure (HR 0.13, CI 0.03-0.68 P = 0.016) and white blood cell count (HR 1.36 per unit increase, CI 1.1-1.69, P = 0.005) on 30-day mortality. CONCLUSIONS: In a selected population of patients percutaneous PIVSD closure is feasible and provides satisfactory survival rate. Procedural success has a protective impact on survival. Timing of the closure remains controversial. Procedure in the non-acute phase carries lower mortality, but at the same time introduces a selection bias. Larger registry-based studies are required.

Incidence, Predictors and Impact of Severe Periprocedural Bleeding According to VARC-2 Criteria on 1-Year Clinical Outcomes in Patients After Transcatheter Aortic Valve Implantation.

There are differences in reporting bleeding complications after transcatheter aortic valve implantation (TAVI), which is a consequence of the lack of consensus for their definition. Furthermore, the amount of data on the impact of peri-procedural bleeding on the mid-term prognosis is still limited. The aim of this study was to investigate the incidence, predictors, and impact of life-threatening and major bleedings as defined by the Valve Academic Research Consortium 2 (VARC-2) in patients after TAVI over the mid-term prognosis.Consecutive patients who underwent TAVI from March 2010 to December 2013 were included. All data were classified according to the VARC-2 criteria. We assessed the incidence and the predictors of serious bleeding events (SBE), defined as life-threatening/disabling (LT/D) or major bleeding, and analyzed their impact on 30-day and 1-year clinical outcome.A total of 129 patients were included (79.1 ± 8.3 years; mean EuroSCORE = 17.8 ± 12.7). The SBE occurred in 25 patients (19.4%), of which 9 (7.0%) had LT/D and 16 (12.4%) had major bleeding. Trans-subclavian (TS) access (OR 4.38, 95% CI 2.13-14.29, P = 0.01) and diabetes (OR 2.93, 95% CI 1.08-7.93, P = 0.03) were identified as independent predictors of SBE. Patients with SBE had higher 30-day mortality (20.0% versus 4.0% P = 0.02) and 1-year mortality (40.0% versus 11.1%, P < 0.002). SBE independently predicted 1-year, all-cause mortality (HR 5.88, 95% CI 1.7319,94, P = 0.005).SBE are frequent after TAVI and are associated with decreased short and mid-term survival. Diabetes and TS access are independent risk factors for SBE.

Incidence and predictors of device-related thrombus after left atrial appendage closure with Watchman device.

Introduction: Left atrial appendage closure (LAAC) with Watchman device prevents thromboembolism in patients with atrial fibrillation (AF). However, thrombus may develop on the atrial surface of the device. Aim: To investigate the incidence and predictors of device-related thrombus (DRT) in patients with AF who were treated with LAAC. Material and methods: Ninety-one consecutive patients with AF underwent LAAC procedure using first-generation Watchman 2.5 device followed by antiplatelet therapy. In our analysis we have included all patients (n = 78) who had clinical follow-up visits with transesophageal echocardiography (TEE) after the procedure. Results: The median (IQR) CHA2DS2-VASc score was 4 (4.0-6.0) and HAS-BLED score was 3 (3.0-4.0). DRTs were observed in 5 (6.4%) patients. When compared with patients without DRT, those with DRT presented more often with lower median ejection fraction (40% (23.5-45.5) versus 55% (48.0-60.0); p = 0.005), lower emptying velocity of LAA (25 cm/s (17.5-27.0) versus 53 cm/s (26.5-78.0); p = 0.009), and with greater depth of implantation (18 mm (14.0-20.5) versus 8 mm (5.0-11.0); p < 0.001). Furthermore, patients with DRT had greater depth of LAA (35 mm (29.5-41.0) versus 29 mm (25.5-31.0); p = 0.003), greater mean (SD) dimension in 900 (22.4 mm (3.2) versus 19 mm (2.7); p = 0.02). Patients with DRT were also younger than those without DRT (67.4 years (7) versus 75 years (8.3), p = 0.045). Conclusions: The DRT after Watchman device implantation remains a rare complication. Its formation was related to several patient and procedural characteristics, which need to be confirmed in larger studies.

Clinical and echocardiographic characterization of patients hospitalized for severe tricuspid valve regurgitation: a single tertiary-care center experience with 2-year follow-up.

INTRODUCTION: Tricuspid regurgitation (TR) is a common acquired valvular heart disease. Recently, new transcatheter treatment options for severe TR have emerged that could change management of this condition, which warrants better characterization of this specific patient group. OBJECTIVES: The aim of the study was to describe the clinical and echocardiographic characteristics of patients with severe TR and to evaluate their short- and mid­term prognosis. PATIENTS AND METHODS: This retrospective, observational, single­center study enrolled consecutive patients with severe TR hospitalized between January 2016 and September 2021 in the Department of Cardiology, Medical University of Warsaw, Poland. The severity of heart failure (HF) was evaluated using the New York Heart Association classification. Echocardiographic assessment was performed by an experienced sonographer. EuroSCORE II and TRI­SCORE models were computed for each patient, and 12- and 24­month clinical outcomes were reported. RESULTS: The study comprised 172 patients (93 women [54.1%]) at a mean (SD) age of 76.4 (10.5) years. The most common comorbidities included: atrial fibrillation (84.9%), hypertension (68%), chronic kidney disease (54.1%), coronary artery disease (45.3%), and diabetes mellitus (30.9%). The median (interquartile range) EuroSCORE II and TRI­SCORE values were 4.68% (2.88%-8.05%) and 14% (5%-34%), respectively. The median follow­up was 24 (8.5-41) months. The overall mortality was 29.7% at 1 year and 47.3% at 2 years. TR grade, tricuspid annular plane systolic excursion (TAPSE) above 17 mm, TAPSE to systolic pulmonary artery pressure ratio below 0.26, and increased right atrial area were significant factors associated with mortality. CONCLUSIONS: Patients presenting with severe TR are characterized by a large comorbidity burden and poor prognosis, despite intensive HF management.

Assessment of symptom severity in psychotic disorder patients based on heart rate variability and accelerometer mobility data.

BACKGROUND: Advancement in mental health care requires easily accessible, efficient diagnostic and treatment assessment tools. Viable biomarkers could enable objectification and automation of the diagnostic and treatment process, currently dependent on a psychiatric interview. Available wearable technology and computational methods make it possible to incorporate heart rate variability (HRV), an indicator of autonomic nervous system (ANS) activity, into potential diagnostic and treatment assessment frameworks as a biomarker of disease severity in mental disorders, including schizophrenia and bipolar disorder (BD). METHOD: We used a commercially available electrocardiography (ECG) chest strap with a built-in accelerometer, i.e. Polar H10, to record R-R intervals and physical activity of 30 hospitalized schizophrenia or BD patients and 30 control participants through ca. 1.5-2 h time periods. We validated a novel approach to data acquisition based on a flexible, patient-friendly and cost-effective setting. We analyzed the relationship between HRV and the Positive and Negative Syndrome Scale (PANSS) test scores, as well as the HRV and mobility coefficient. We also proposed a method of rest period selection based on R-R intervals and mobility data. The source code for reproducing all experiments is available on GitHub, while the dataset is published on Zenodo. RESULTS: Mean HRV values were lower in the patient compared to the control group and negatively correlated with the results of the PANSS general subcategory. For the control group, we also discovered the inversely proportional dependency between the mobility coefficient, based on accelerometer data, and HRV. This relationship was less pronounced for the treatment group. CONCLUSIONS: HRV value itself, as well as the relationship between HRV and mobility, may be promising biomarkers in disease diagnostics. These findings can be used to develop a flexible monitoring system for symptom severity assessment.

Assessment of knowledge and beliefs concerning mental disorders among medical students - preliminary report. / Ocena postaw wobec osób z zaburzeniami psychicznymi wsród studentów medycyny - doniesienie wstepne.

OBJECTIVES: The aim of the study was to assess attitudes towards people with mental disorders. METHODS: The survey was carried out in a group of 93 students of the fifth year of medical studies (medical faculty) including 59 women and 34 men, aged 24.34 ± 1.28 years. RESULTS: In the conducted research, personal contact with a psychiatrist due to problems with their own mental health was declared by 23% of respondents. The choice of psychiatry as a field of specialization was declared by 19% of students. In the analysis of the questionnaire on beliefs, as many as 83% of respondents considered that mental illness is a cause for shame. Analyzing the attitude of the respondents to treatment, it was shown that as many as 80% of people believed that compulsory hospitalization is a right procedure. It should be emphasized that only 31% of the surveyed students believed that people with mental disorders should decide to have offspring, and 36% of people thought that mentally disturbed people would not be good as parents. As many as 30% of respondents believed that people with mental disorders more often commit crimes than healthy people, and 42% of students showed a lack of determination in this aspect. CONCLUSIONS: The results of the research suggest the necessity of expanding knowledge and shaping appropriate attitudes towards people with mental disorders among future doctors.

Safety and efficacy of percutaneous atrial appendage closure followed by antiplatelet therapy in a high-risk population: single-center experience with a WATCHMAN device.

Introduction: In our everyday practice we encounter many patients with non-valvular atrial fibrillation with either a contraindication to oral anticoagulation or with its inefficiency. Aim: To investigate whether left atrial appendage closure (LAAC) followed by post-procedure antiplatelet therapy is safe and efficient in a high-risk population. Material and methods: Ninety-one (48 males) consecutive patients with non-valvular atrial fibrillation (NVAF) underwent an LAAC procedure using a first-generation WATCHMAN 2.5 device followed by antiplatelet therapy. Clinical and transesophageal echocardiography data were collected at baseline and at the follow-up visit. Results: The median (IQR) CHA2DS2-VASc score was 5 (4.0-6.0) and the HAS-BLED score was 3 (3.0-4.0); the mean (SD) age was 74.4 (8.4). A bleeding history was observed in 89% of patients and 24.2% of patients had a history of stroke or transient ischemic attack (TIA). The procedure was successful in 98.9%. Post-procedure therapy was dual antiplatelet therapy in 85 patients; 3 patients received single antiplatelet therapy and the therapy was maintained until the follow-up visit. Peri-procedural complications were tamponade (3.3%), pericardial effusion (2.2%) and two deaths (2.2%) with no bleeding or vascular complications. The median follow-up was 67 (52.75-84.75) days. Primary safety endpoint (bleeding BARC type 3 or more, tamponade, pericardial effusion, and device embolization) and primary efficacy endpoint (stroke or TIA, hemorrhagic stroke, peripheral embolism, cardiovascular (CV) and non-CV death) were observed in 2 and 4 patients, respectively. Conclusions: The LAAC procedure followed by antiplatelet therapy seems to be safe and efficient in the high-risk population. Further studies in this field are required.

Impact of previous coronary artery revascularization on outcomes in patients undergoing transcatheter aortic valve implantation.

Introduction: Coexistence of coronary artery disease (CAD) in patients with severe aortic stenosis (AS) referred for transcatheter aortic valve implantation (TAVI) raises questions regarding the safety and efficacy of TAVI in this subset of patients. Aim: To evaluate the impact of previous coronary revascularization in terms of percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) on clinical outcomes after TAVI. Material and methods: A total of 507 consecutive patients who underwent TAVI were divided into: non-revascularization (NR), post-PCI and post-CABG groups. The endpoints were established according to VARC-2 definitions. Results: Patients with previous coronary revascularization (36.7% of the population) were younger, more often male and their EuroSCORE II risk evaluation was significantly higher (NR 7.9% vs. post-PCI 8.0% vs. post-CABG 20.5%, p < 0.0001). Patients after PCI or CABG prior to TAVI had similar 30-day all-cause mortality rates as those without coronary revascularization at baseline (NR vs. post-PCI vs. post-CABG: 8.1% vs. 5.5% vs. 6.8%, respectively; p = 0.6). There were no differences in 12-month all-cause mortality rates between groups (NR vs. post-PCI vs. post-CABG: 15.3% vs. 14.2% vs. 16.9%, respectively; log-rank p = 0.67). In the Cox proportional-hazards regression model, acute kidney injury stage 2-3 (HR = 3.7, 95% CI: 2.14-6.33; p < 0.001) and post-TAVI stroke (HR = 3.5, 95% CI: 1.57-7.8; p = 0.002) were independently correlated with 1-year mortality. Conclusions: TAVI seems to be a safe and effective procedure for the treatment of severe AS in patients with previous coronary revascularization.

Impact of Enterococci vs. Staphylococci Induced Infective Endocarditis after Transcatheter Aortic Valve Implantation.

BACKGROUND: The two most common organisms found in infective endocarditis following transcatheter aortic valve implantation (TAVI-IE) are enterococci (EC-IE) and staphylococci (SC-IE). We aimed to compare clinical characteristics and outcomes of patients with EC-IE and SC-IE. METHODS: TAVI-IE patients from 2007 to 2021 were included in this analysis. The 1-year mortality was the primary outcome measure of this retrospective multi-center analysis. RESULTS: Out of 163 patients, 53 (32.5%) EC-IE and 69 (42.3%) SC-IE patients were included. Subjects were comparable with regard to age, sex, and clinically relevant baseline comorbidities. Symptoms at admission were not significantly different between groups, except for a lower risk for presenting with septic shock in EC-IE than SC-IE. Treatment was performed in 78% by antibiotics alone and in 22% of patients by surgery and antibiotics, with no significant differences between groups. The rate of any complication, in particular heart failure, renal failure, and septic shock during treatment for IE, was lower in EC-IE compared with SC-IE (p < 0.05). In-hospital (EC-IE: 36% vs. SC-IE: 56%, p = 0.035) and 1-year mortality (EC-IE: 51% vs. SC-IE: 70%, p = 0.009) were significantly lower in EC-IE compared with SC-IE. CONCLUSIONS: EC-IE, compared with SC-IE, was associated with a lower morbidity and mortality. However, absolute numbers are high, a finding that should trigger further research in appropriate perioperative antibiotic management and improvement of early IE diagnosis in the case of clinical suspicion.

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.

Risk of left atrial appendage thrombus in older patients with atrial fibrillation.

Introduction: We aimed to compare the prevalence of left atrial appendage (LAA) thrombus and its predictors between old and young patients with atrial fibrillation (AF). Material and methods: The study included 1970 patients aged ≥ 65 (n = 822 (41.7%)) and < 65 (n = 1148 (58.3%)) referred for AF cardioversion or ablation preceded by transoesophageal echocardiography (TEE). Results: Oral anticoagulation (OAC) was prescribed in 799 (97.2%) patients aged ≥ 65 years and in 1054 (91.8%) of those aged < 65 years (p < 0.001). In patients treated with OAC, those aged ≥ 65 years less often received vitamin K antagonist (VKA) (267 (33.4%) vs. 416 (39.5%)) and more often non-VKA-OAC (NOAC) (532 (66.6%) vs. 638 (60.5%), p = 0.008, p = 0.008) compared to patients < 65 years. On TEE, LAA thrombus was more often observed in patients aged ≥ 65 years than those aged < 65 years (63 (7.7%) vs. 46 (4.0%), p < 0.001), with an absolute but not statistically significant difference between patients aged 65-74 and ≥ 75 years (47 (7.3%) vs. 16 (8.8%), p = 0.528). In patients aged ≥ 65 years, there was no difference in the prevalence of LAA thrombus between patients treated with VKA and NOAC, in contrast to patients aged < 65 years, in whom such a difference was observed (27 (6.5%) vs. 16 (2.5%), p = 0.002). In multivariate logistic regression, predictors of LAA thrombus in both age groups were older age, non-paroxysmal AF, and heart failure, whereas only in patients aged < 65 years - VKA use, and in those aged ≥ 65 years - lower glomerular filtration rate and platelet count. Conclusions: Despite OAC use, older patients with AF remain at high risk of LAA thrombus formation. Older age, non-paroxysmal AF, and heart failure are predictors of LAA thrombus, irrespective of age.

[The association of quality of life with mental status and sociodemographic data in schizophrenic patients]. / Ocena wplywu wybranych czynników psychicznych i socjodemograficznych na jakosc zycia pacjentów ze schizofrenia.

AIM: The aim of this study was to assess the mental status and sociodemographic data as well as their influence on the quality of life in schizophrenic patients. METHODS: SF-36, Soc-29, CDS, PANSS, AIS and sociodemographic questionnaire were given to a cohort of 64 subjects who participated in this study (28 female, 36 male), with age range of 21-58 (Mean 33.4 +/- 10.8). Questionnaires were administered to all patients in partly-remission or remission time. RESULTS: Patients showed significant positive correlation of summary scales of PCS and MCS with SOC and AIS and negative correlation with depression symptoms estimated by CDS. There were no significant differences in MCS and sociodemographic factors. The values of the PCS were negatively associated with the number of hospitalisations, disease duration time and negative syndromes estimated by PANSS-N. CONCLUSIONS: Sense of coherence, acceptance of illness and depressive syndromes influence quality of life.
