RESUMO

BACKGROUNDS: Permanent pacemaker implantation (PPMI) is one of the greatest disadvantages of transcatheter aortic valve implantation (TAVI). To seek the predictors and clinical impacts of PPMI and investigate the recovery rate from conduction disorders. METHODS: We retrospectively analysed data from 745 consecutive patients who underwent TAVI for severe aortic stenosis from November 2013 to July 2022. The ventricular pacing (VP) rate was recorded at 1 and 6 months after PPMI and the recovery from conduction disorders was defined as the VP rate <1%. RESULTS: Postoperative PPMI was performed in 7.1% (53/745) of patients. Balloon predilatation was significantly frequent in the PPMI (-) group (52.8% (28/53) vs 80.6% (558/692); p<0.001) and the oversizing ratio was significantly greater in the PPMI (+) group (11.8%±10.1% vs 9.1%±9.7%; p=0.035). Freedom from rehospitalisation due to heart failure rate was significantly higher in the PPMI (-) group (p=0.032). In patients with postoperative PPMI, recovery from conduction disorders was observed in 17.0% and 27.9% of patients at 1 and 6 months, respectively. CONCLUSIONS: Recovery from conduction disorders occurred frequently. Avoidance of oversizing and extension of observation time may reduce the need for PPMI after TAVI.

RESUMO

BACKGROUND: Research on the role of transcatheter heart valve (THV) deformation and calcium distribution in patients with bicuspid aortic valves (BAVs) undergoing transcatheter aortic valve replacement (TAVR) remains limited. OBJECTIVES: The aim of this study was to evaluate the impact of THV deformation on clinical outcomes in individuals with BAVs undergoing TAVR and the influence of calcium on these outcomes. METHODS: In total, 229 consecutive patients with BAVs who underwent TAVR with balloon-expandable valves and had computed tomography (CT) performed 30 days post-TAVR were analyzed. Patients were stratified into 3 groups: group 1 (n = 125), with no THV underexpansion or eccentricity; group 2 (n = 69), with underexpansion or eccentricity; and group 3 (n = 35), with both. Calcium distribution was assessed using CT, and its associations with clinical outcomes, including all-cause mortality at 3 years and leaflet thrombosis at 30 days, were determined. A subgroup analysis of patients with type 1 BAVs was conducted. RESULTS: Group 3 exhibited higher rates of all-cause mortality than the other groups, along with the highest risk for hypoattenuated leaflet thickening at 30 days. Multivariate analysis identified annular and left ventricular outflow tract calcification as independent predictors of all-cause mortality and hypoattenuated leaflet thickening. In patients with type 1 BAVs, excessive calcification at the raphe and opposite leaflet were associated with all-cause mortality at 3 years. CONCLUSIONS: THV deformation post-TAVR was significantly linked to all-cause mortality in patients with BAVs. Annular and left ventricular outflow tract calcification correlated with increased risks for all-cause mortality and leaflet thrombosis.

RESUMO

BACKGROUND: Fluid overload (FO) subjects patients with severe aortic stenosis (AS) to increased risk for heart failure and death after valve replacement and can be objectively quantified using bioimpedance spectroscopy (BIS). OBJECTIVES: The authors hypothesized that in AS patients with concomitant FO, BIS-guided decongestion could improve prognosis and quality of life following transcatheter aortic valve replacement (TAVR). METHODS: This randomized, controlled trial enrolled 232 patients with severe AS scheduled for TAVR. FO was defined using a portable whole-body BIS device according to previously established cutoffs (≥1.0 L and/or ≥7%). Patients with FO (n = 111) were randomly assigned 1:1 to receive BIS-guided decongestion (n = 55) or decongestion by clinical judgment alone (n = 56) following TAVR. Patients without FO (n = 121) served as a control cohort. The primary endpoint was the composite of hospitalization for heart failure and/or all-cause death at 12 months. The secondary endpoint was the change from baseline to 12 months in the Kansas City Cardiomyopathy Questionnaire. RESULTS: The occurrence of the primary endpoint at 12 months was significantly lower in the BIS-guided vs the non-BIS-guided decongestion group (7/55 [12.7%, all deaths] vs 18/56 [32.1%, 9 hospitalizations for heart failure and 9 deaths]; HR: 0.36; 95% CI: 0.15-0.87; absolute risk reduction = -19.4%). Outcomes in the BIS-guided decongestion group were identical to the euvolemic control group (log-rank test, P = 0.7). BIS-guided decongestion was also associated with a higher increase in the Kansas City Cardiomyopathy Questionnaire score from baseline compared to non-BIS-guided decongestion (P = 0.001). CONCLUSIONS: In patients with severe AS and concomitant FO, quantitatively guided decongestive treatment and associated intensified management post-TAVR was associated with improved outcomes and quality of life compared to decongestion by clinical judgment alone.

RESUMO

BACKGROUND: Asymmetrical expansion of transcatheter heart valves (THVs), manifesting as stent frame deformation, is an occasional fluoroscopic finding in transcatheter aortic valve replacement (TAVR). OBJECTIVES: The aim of this study was to investigate the impact of asymmetrical expansion of balloon-expandable THVs on hemodynamic valve performance and clinical outcomes. METHODS: In a prospective registry, TAVR asymmetry index was measured using freeze-frame fluoroscopic images and was defined as the ratio of THV heights: [(longer height/shorter height) - 1] × 100. THV hemodynamic performance was measured using echocardiography before hospital discharge. Impaired hemodynamic valve performance was defined as a mean residual THV gradient ≥20 mm Hg and/or moderate or greater paravalvular regurgitation. RESULTS: Among 1,216 patients undergoing transfemoral TAVR for native severe aortic valve stenosis with contemporary balloon-expandable THVs between February 2014 and June 2022, asymmetry index was an excellent predictor of impaired hemodynamic valve performance (area under the receiver-operating characteristic curve: 0.88; 95% CI: 0.84-0.92; P < 0.001). The optimal asymmetry index threshold for predicting impaired THV performance was >5.5% (sensitivity 77%, specificity 86%) and occurred in 17% of patients. Higher asymmetry index, as a continuous variable, was associated with impaired hemodynamic valve performance independent of total aortic valve calcium, bicuspid anatomy, balloon-expandable valve prosthesis type or size, and Society of Thoracic Surgeons Predicted Risk of Mortality score (OR: 1.37; 95% CI: 1.29-1.46; P < 0.001). High TAVR asymmetry index was not associated with all-cause mortality during a median of 376 days of follow-up (HR: 1.00; 95% CI: 0.71-1.41; P = 0.989). CONCLUSIONS: Asymmetrical expansion of balloon-expandable THVs was associated with impaired hemodynamic valve performance but not with clinical outcomes.

RESUMO

BACKGROUND: Large datasets of transcatheter aortic valve implantation (TAVI) for pure aortic valve regurgitation (PAVR) are scarce. AIMS: We aimed to report procedural safety and long-term clinical events (CE) in a contemporary cohort of PAVR patients treated with new-generation devices (NGD). METHODS: Patients with grade III/IV PAVR enrolled in the FRANCE-TAVI Registry were selected. The primary safety endpoint was technical success (TS) according to Valve Academic Research Consortium 3 criteria. The co-primary endpoint was defined as a composite of mortality, heart failure hospitalisation and valve reintervention at last follow-up. RESULTS: From 2015 to 2021, 227 individuals (64.3% males, median age 81.0 [interquartile range {IQR} 73.5-85.0] years, with EuroSCORE II 6.0% [IQR 4.0-10.9]) from 41 centres underwent TAVI with NGD, using either self-expanding (55.1%) or balloon-expandable valves (44.9%; p=0.50). TS was 85.5%, with a non-significant trend towards increased TS in high-volume activity centres. A second valve implantation (SVI) was needed in 8.8% of patients, independent of valve type (p=0.82). Device size was ≥29 mm in 73.0% of patients, post-procedure grade ≥III residual aortic regurgitation was rare (1.2%), and the permanent pacemaker implantation (PPI) rate was 36.0%. At 30 days, the incidences of mortality and reintervention were 8.4% and 3.5%, respectively. The co-primary endpoint reached 41.6% (IQR 34.4-49.6) at 1 year, increased up to 61.8% (IQR 52.4-71.2) at 4 years, and was independently predicted by TS, with a hazard ratio of 0.45 (95% confidence interval: 0.27-0.76); p=0.003. CONCLUSIONS: TAVI with NGD in PAVR patients is efficient and reasonably safe. Preventing the need for an SVI embodies the major technical challenge. Larger implanted valves may have limited this complication, outweighing the increased risk of PPI. Despite successful TAVI, PAVR patients experience frequent CE at long-term follow-up.

RESUMO

Aortic regurgitation (AR) is a common clinical disease associated with significant morbidity and mortality. Investigations based largely on non-invasive imaging are pivotal in discerning the severity of disease and its impact on the heart. Advances in technology have contributed to improved risk stratification and to our understanding of the pathophysiology of AR. Surgical aortic valve replacement is the predominant treatment. However, its use is limited to patients with an acceptable surgical risk profile. Transcatheter aortic valve implantation is an alternative treatment. However, this therapy remains in its infancy, and further data and experience are required. This review article on AR describes its prevalence, mechanisms, diagnosis and treatment.

RESUMO

BACKGROUND: Paravalvular regurgitation (PVR) is a common complication after transcatheter aortic valve replacement, posing an increased risk of heart failure and mortality. Accurate intraprocedural quantification of PVR is challenging. Both hemodynamic indices and videodensitometry can be used for intraprocedural assessment of PVR. We compared the predictive value of the isolated versus combined use of the hemodynamic index diastolic delta (DD) and videodensitometry for the incidence of relevant PVR 1 month after transcatheter aortic valve replacement. METHODS AND RESULTS: In this prospective cohort study, patients underwent periprocedural PVR assessment by DD and videodensitometry (using left ventricular outflow tract-aortic regurgitation [LVOT-AR]). Cardiac magnetic resonance served as reference modality for PVR assessment. Relevant PVR was defined as cardiac magnetic resonance-regurgitant fraction >20%. Fifty-one patients were enrolled in this study. Mean age was 80.6±5.2 years and 45.1% of patients were men. Mean LVOT-AR and cardiac magnetic resonance-regurgitant fraction were 8.2%±7.8% and 11.7%±9.6%, respectively. The correlation between DD and LVOT-AR was weak (r=-0.36). DD and LVOT-AR showed a comparable accuracy to predict relevant PVR (area under the curve 0.82, 95% CI: 0.69-0.95 versus area area under the time-density curve 0.80, 95% CI: 0.62-0.99). The combination of DD and LVOT-AR improved the prediction of relevant PVR (area under the time-density curve, 0.90, 95% CI: 0.81-0.99), and resulted in an increased concordance (86.3%) and positive predictive value (75%) compared with DD alone (76.5% and 40%, respectively), or LVOT-AR alone (82.3% and 50%, respectively). CONCLUSIONS: DD and videodensitometry are both accurate and feasible modalities for the assessment of PVR after transcatheter aortic valve replacement. The synergistic use of both techniques increases the predictive value for relevant PVR after transcatheter aortic valve replacement.

RESUMO

BACKGROUND: Inflammation following transcatheter aortic valve implantation (TAVI) is associated with an increased risk of adverse outcomes. The aim of this study was to compare the inflammatory response between low radial force valves (Acurate neo2, Boston Scientific) and high radial force valves (Evolut R/Pro, Medtronic; SAPIEN Edwards Lifesciences; and Myval, Meril valves). METHODS: We conducted a retrospective study of patients with severe aortic stenosis treated with TAVI between 2021 and 2022. The primary endpoint was the difference in the inflammatory response between low radial force valves and high radial force valves, measured as the difference between post-procedural and pre-procedural high-sensitivity C-reactive protein levels (hsCRP delta). RESULTS: A total of 114 patients were included, of which 65 patients (57%) received a low radial force valve. The hsCRP delta was lower in the low radial force valve group compared to the high radial force valve group (8.7 [2.1-15.6] mg/L vs. 18.8 mg/dL [6.4-19] mg/L; P=0.003), due to a lower post-implantation hsCRP (8.9 [5.45-19.6] mg/L vs. 15.8 [9.8-27.3] mg/L; P=0.013). The incidence of new left bundle branch block (LBBB) after TAVI was lower in the low radial force valve group compared to the high radial force valve group (11 [17%] vs. 18 [37%]; P=0.020). CONCLUSIONS: Low radial force TAVI prostheses were associated with a lower inflammatory response, and a lower incidence of new LBBB compared to the radial force valve group, suggesting that inflammation may contribute to the increased risk of conduction disturbances.

RESUMO

BACKGROUND: Degenerative severe aortic valve stenosis (AS) is increasingly prevalent in the aging population, leading to the adoption of transcatheter aortic valve replacement (TAVR) as a less invasive alternative. While TAVR indications have expanded, the procedure is associated with a substantial incidence of major adverse cardiac events (MACE). The study aims to establish a preoperative risk-stratification system for TAVR candidates based on Sokolow-Lyon voltage (SLV) and other relevant factors. METHODS: A total of 181 consecutive patients who underwent TAVR were retrospectively reviewed. Baseline characteristics, preoperative electrocardiogram (ECG) and echocardiography findings, and TAVR procedures were assessed. Low SLV (<3.5 mV) was defined based on ECG measurements. RESULTS: Baseline characteristics revealed a mean age of 84 years, with 71.8% females. The two-year incidence of MACE defined as a composite of cardiac death and hospitalization due to heart failure, was 11.6%, significantly higher in the low SLV group. Low SLV emerged as an independent prognostic factor. The Tokyo Bay Risk (TBR) Score, including low SLV, Body Mass Index <18.5 kg/m2, and previous coronary artery disease, effectively stratified MACE risk. Higher TBR scores (2 or 3) correlated with increased MACE risk. CONCLUSIONS: Patients with low SLV in pre-procedural ECG demonstrated a heightened risk of two-year MACE. The TBR score, incorporating low SLV, proved valuable for preoperative risk assessment. Careful consideration of TAVR indications, along with TBR score integration, is crucial for optimizing outcomes.

RESUMO

BACKGROUND: Acute intraoperative hypercapnia and respiratory acidosis, which can occur during monitored anaesthesia care (MAC), pose significant cardiopulmonary risks for patients with aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). The goal of the present study is to assess the incidence, risk factors and impact of intraoperative hypercapnia during MAC for patients undergoing transfemoral TAVR. METHODS: Data was collected retrospectively from the electronic medical record of 201 consecutive patients with available intraoperative arterial blood gas (ABG) data who underwent percutaneous transfemoral TAVR with MAC using propofol and dexmedetomidine. ABGs (pH, arterial partial pressure of carbon dioxide (PaCO2) and arterial partial pressure of oxygen) were performed at the start of each case (baseline), immediately prior to valve deployment (ValveDepl), and on arrival to the postanaesthesia care unit. Data was analysed using Fisher's exact test, unpaired Student's t-test, Wilcoxon rank sum or univariate linear regression as appropriate based on PaCO2 and pH during ValveDepl (PaCO2-ValveDepl, pH-ValveDepl) and change in PaCO2 and pH from baseline to ValveDepl (PaCO2-%increase, pH-%decrease) to determine their association with preoperative demographic data, intraoperative anaesthetic and vasoactive medications and postoperative outcomes. RESULTS: PaCO2 increased by a mean of 28.4% and was higher than baseline in 91% of patients. Younger age, male sex, increased weight and increased propofol dose contributed to higher PaCO2-ValveDepl and greater PaCO2-%increase. Patients with PaCO2-ValveDepl>60 mm Hg, pH≤7.2 and greater pH-%decrease were more likely to receive vasoactive medications, but perioperative PaCO2 and pH were not associated with adverse postoperative outcomes. CONCLUSIONS: Transient significant hypercapnia commonly occurs during transfemoral TAVR with deep sedation using propofol and dexmedetomidine. Although the incidence of postoperative outcomes does not appear to be affected by hypercapnia, the need for vasopressors and inotropes is increased. If deep sedation is required for TAVR, hypercapnia and the need for haemodynamic and ventilatory support should be anticipated.

RESUMO

As a consequence of the growing number of implanted transcatheter aortic valve prostheses, the increasing incidence of early and late complications of biological valves requires in several cases surgical explantation of the transcatheter valve and subsequent aortic root or surgical aortic valve replacement. In this video tutorial, we show how to avoid aortic root damage in the surgical explantation of a transcatheter aortic valve bioprosthesis in a patient with a dysfunctional transcatheter aortic valve prosthesis affected by endocarditis 15 months after implantation. The infected prosthesis and all foreign materials, concomitant to the calcified native valve, were excised en bloc in preparation for the extensive debridement of infected tissue in the abscess cavity. The defect on the aortic annulus was reconstructed using a pericardial patch, followed by a surgical valve implant.

RESUMO

BACKGROUND: Cerebrovascular events remain one of the most devastating complications of transcatheter aortic valve implantation (TAVI). Data from real-world contemporary cohorts on longitudinal trends and outcomes remain limited. The aim of this study was to assess incidence, temporal trends, predictors, and outcomes of cerebrovascular events following transfemoral TAVI. METHODS AND RESULTS: The CENTER2 (Cerebrovascular Events in Patients Undergoing Transcatheter Aortic Valve Implantation With Balloon-Expandable Valves Versus Self-Expandable Valves 2) study includes patients undergoing TAVI between 2007 and 2022. The database contains pooled patient-level data from 10 clinical studies. A total of 24 305 patients underwent transfemoral TAVI (mean age 81.5±6.7 years, 56% women, median Society of Thoracic Surgeon Predicted Risk of Mortality 4.9% [3.1%-8.5%]). Of these patients, 2.2% (n=534) experienced stroke in the first 30 days after TAVI, and 40 (0.4%) had a transient ischemic attack. Stroke rates remained stable during the treatment period (2007-2010: 2.1%, 2011-2014: 2.5%, 2015-2018: 2.1%, 2019-2022: 2.1%; Ptrend=0.28). Moreover, 30-day cerebrovascular event rates were similar across Society of Thoracic Surgeon Predicted Risk of Mortality risk categories: 2.1% in low-risk, 2.6% in intermediate-risk, and 2.5% in high-risk patients (P=0.21). Mortality was higher in patients with 30-day stroke than without at 30 days (20.3% versus 4.7%; odds ratio, 5.1 [95% CI, 4.1-6.5]; P<0.001) and at 1 year (44.1% versus 15.0%; hazard ratio, 3.5 [95% CI, 3.0-4.2]; P<0.001). One-year mortality rates for stroke did not decline over time (2007-2010: 46.9%, 2011-2014: 46.0%, 2015-2018: 43.0%, 2019-2022: 39.1%; Ptrend=0.32). At 1 year, 7.0% of patients undergoing TAVI had a stroke. CONCLUSIONS: In 24 305 patients who underwent transfemoral TAVI, 30-day cerebrovascular event incidence remained ≈ 2.2% between 2007 and 2022. Thirty-day stroke rates were similar throughout Society of Thoracic Surgeon Predicted Risk of Mortality risk categories. Mortality rates after stroke remain high.

RESUMO

BACKGROUND: Tricuspid regurgitation (TR) is associated with worse clinical outcomes after transcatheter aortic valve replacement (TAVR) and mitral transcatheter edge-to-edge repair (M-TEER), but little is known about its association with health status outcomes. OBJECTIVES: The aims of this study were to explore, using the Society of Thoracic Surgeons and American College of Cardiology TVT (Transcatheter Valve Therapy) Registry, the association between baseline TR and health status after TAVR and M-TEER and to determine if baseline TR was associated with clinical endpoints. METHODS: Health status was assessed using Kansas City Cardiomyopathy Questionnaire overall summary (KCCQ-OS) score in patients enrolled in the TVT Registry who underwent isolated TAVR or M-TEER between January 2019 and June 2021. The association among baseline TR and KCCQ-OS score, being alive and well, and clinical outcomes was examined. RESULTS: In total, 130,097 TAVR patients (13.1% with moderate TR, 2.3% with severe TR) and 19,593 M-TEER patients (33.2% with moderate TR, 14.7% with severe TR) were included. Mean KCCQ-OS scores were lower with severe vs moderate vs none to mild TR at baseline prior to TAVR (39.4 ± 24.2 vs 45.2 ± 24.7 vs 51.3 ± 25.3; P < 0.01) or M-TEER (38.1 ± 23.9 vs 41.9 ± 24.7 vs 45.4 ± 25.2; P < 0.01) and similarly at 30 days and 1 year. The odds of being alive and well at 1 year were lower with moderate or severe TR before TAVR (adjusted OR: 0.79 [95% CI: 0.74-0.85] and adjusted OR: 0.81 [95% CI: 0.70-0.94], respectively) and severe TR before M-TEER (adjusted OR: 0.53; 95% CI: 0.40-0.71). Furthermore, moderate or severe TR before TAVR was associated with higher 1-year mortality and readmission, whereas moderate or severe TR before M-TEER was associated with higher 1-year mortality. CONCLUSIONS: In a large cohort of U.S. patients who underwent TAVR or M-TEER, greater baseline TR was associated with worse health status and clinical outcomes. Understanding adverse outcomes of TR in patients with coexisting valvular abnormalities is important, especially with rapidly evolving transcatheter tricuspid valve interventions.

RESUMO

BACKGROUND: Tricuspid regurgitation (TR) is highly prevalent in the transcatheter aortic valve replacement (TAVR) population, but clear management guidelines are lacking. OBJECTIVES: The aims of this study were to elucidate the prevalence and consequences of severe TR in patients with aortic stenosis undergoing TAVR and to examine the change in TR post-TAVR, including predictors of improvement and its impact on longer term mortality. METHODS: Using Centers for Medicare and Medicaid Services-linked TVT (Transcatheter Valve Therapy) Registry data, a propensity-matched analysis was performed among patients undergoing TAVR with baseline mild, moderate, or severe TR. Kaplan-Meier estimates were used to assess the impact of TR on 3-year mortality. Multivariable analysis identified predictors of 30-day TR improvement. RESULTS: Of the 312,320 included patients, 84% had mild, 13% moderate, and 3% severe TR. In a propensity-matched cohort, severe baseline TR was associated with higher in-hospital mortality (2.5% vs 2.1% for moderate TR and 1.8% for mild TR; P = 0.009), higher 1-year mortality (24% vs 19.6% for moderate TR and 16.6% for mild TR; P < 0.0001), and 3-year mortality (54.2% vs 48.5% for moderate TR and 43.3% for mild TR; P < 0.0001). Among the patients with severe TR at baseline, 76.4% improved to moderate or less TR 30 days after TAVR. Baseline mitral regurgitation moderate or greater, preserved ejection fraction, higher aortic valve gradient, and better kidney function predicted TR improvement after TAVR. However, severe 30-day residual TR was associated with higher 1-year mortality (27.4% vs 18.7% for moderate TR and 16.8% for mild TR; P < 0.0001). CONCLUSIONS: Severe baseline and 30-day residual TR after TAVR are associated with increased mortality up to 3 years. This analysis identifies a higher risk group that could be evaluated for the recently approved tricuspid interventions.
