RESUMO
BACKGROUND: Scarce data are available comparing infective endocarditis (IE) following surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR). This study aimed to compare the clinical presentation, microbiological profile, management, and outcomes of IE after SAVR versus TAVR. METHODS: Data were collected from the "Infectious Endocarditis after TAVR International" (enrollment from 2005 to 2020) and the "International Collaboration on Endocarditis" (enrollment from 2000 to 2012) registries. Only patients with an IE affecting the aortic valve prosthesis were included. A 1:1 paired matching approach was used to compare patients with TAVR and SAVR. RESULTS: A total of 1688 patients were included. Of them, 602 (35.7%) had a surgical bioprosthesis (SB), 666 (39.5%) a mechanical prosthesis, 70 (4.2%) a homograft, and 350 (20.7%) a transcatheter heart valve. In the SAVR versus TAVR matched population, the rate of new moderate or severe aortic regurgitation was higher in the SB group (43.4% vs 13.5%; P < .001), and fewer vegetations were diagnosed in the SB group (62.5% vs 82%; P < .001). Patients with an SB had a higher rate of perivalvular extension (47.9% vs 27%; P < .001) and Staphylococcus aureus was less common in this group (13.4% vs 22%; P = .033). Despite a higher rate of surgery in patients with SB (44.4% vs 27.3%; P < .001), 1-year mortality was similar (SB: 46.5%; TAVR: 44.8%; log-rank P = .697). CONCLUSIONS: Clinical presentation, type of causative microorganism, and treatment differed between patients with an IE located on SB compared with TAVR. Despite these differences, both groups exhibited high and similar mortality at 1-year follow-up.

AIMS: We aimed to evaluate transcatheter mitral valve implantation (TMVI) using predominantly balloon-expandable transcatheter heart valves (THV) in patients with a landing zone for a percutaneously delivered prosthesis. BACKGROUND: Patients with a degenerated mitral valve bioprosthesis, annuloplasty ring, and mitral annulus calcification (MAC) considered at high surgical risk currently represent a treatment challenge. TMVI is an alternative treatment option. METHODS: Retrospective analysis of patients with symptomatic degenerated mitral valve bioprosthesis, or annuloplasty ring, and MAC treated with TMVI between November 2011 and April 2021. Endpoints were defined according to Mitral Valve Academic Research Consortium (MVARC) criteria and included device and procedure success at 30 days as well as mortality at 30 days and 1 year after the procedure. RESULTS: A total of 77 patients underwent TMVI (valve in valve [ViV = 56], valve in ring [ViR = 11], and valve in MAC [ViMAC = 10]). There was a trend toward higher technical success (all = 93.5%, ViV = 96.4%, ViR = 90.9%, ViMAC = 80%, p = 0.06) and lower 30-day (all = 11.7%, ViV = 10.7%, ViR = 9.1%, ViMAC = 20%, p = 0.49) and 1-year mortality (all = 26%, ViV = 23.2%, ViR = 27.3%, ViMAC= 40%, p = 0.36) after ViV and ViR compared to ViMAC. CONCLUSION: TMVI represents a reasonable treatment option in selected patients with MAC or who are poor candidates for redo mitral valve surgery. Technical success and survival up to 1 year were not significantly dependent on the subgroup in which TMVI was performed.
RESUMO
Aortic valve stenosis is one of the most frequent valvular heart diseases requiring treatment in industrialized countries. The symptom onset is associated with a significantly increased mortality, so that there is a clear indication for treatment in patients with severe, symptomatic aortic valve stenosis; however, data on the optimal treatment of patients with asymptomatic aortic valve stenosis are scarce. Smaller studies in the field of cardiac surgery suggest that early surgical valve replacement is superior to a conservative approach. For this reason, the results of additional adequately powered randomized trials are awaited with great interest. In this year numerous long-term results from randomized comparisons of the two available treatment options (surgical versus transcatheter aortic valve replacement) were published, which will further guide the heart team to find the best treatment approach for each individual.

BACKGROUND: Echocardiography is the primary imaging modality for diagnosis of infective endocarditis (IE) in prosthetic valve endocarditis (PVE) including IE after transcatheter aortic valve implantation (TAVI). This study aimed to evaluate the characteristics and clinical outcomes of patients with absent compared with evident echocardiographic signs of TAVI-IE. METHODS: Patients with definite TAVI-IE derived from the Infectious Endocarditis after TAVI International Registry were investigated comparing those with absent and evident echocardiographic signs of IE defined as vegetation, abscess, pseudo-aneurysm, intracardiac fistula, or valvular perforation or aneurysm. RESULTS: Among 578 patients, 87 (15.1%) and 491 (84.9%) had absent (IE-neg) and evident (IE-pos) echocardiographic signs of IE, respectively. IE-neg were more often treated via a transfemoral access with a self-expanding device and had higher rates of peri-interventional complications (eg, stroke, major vascular complications) during the TAVI procedure (P < .05 for all). IE-neg had higher rates of IE caused by Staphylococcus aureus (33.7% vs 23.2%; P = .038) and enterococci (37.2% vs 23.8%; P = .009) but lower rates of coagulase-negative staphylococci (4.7% vs 20.0%, P = .001). IE-neg was associated with the same dismal prognosis for in-hospital mortality in a multivariate binary regression analysis (odds ratio: 1.51; 95% confidence interval [CI]: .55-4.12) as well as a for 1-year mortality in Cox regression analysis (hazard ratio: 1.10; 95% CI: .67-1.80). CONCLUSIONS: Even with negative echocardiographic imaging, patients who have undergone TAVI and presenting with positive blood cultures and symptoms of infection are a high-risk patient group having a reasonable suspicion of IE and the need for an early treatment initiation.

BACKGROUND: Transcatheter aortic valve implantation (TAVI) was established as a standard treatment for high-operative risk patients with severe aortic stenosis (AS). Although coronary artery disease (CAD) often coexists with AS, clinical and angiographic evaluations of stenosis severity are unreliable in this specific setting. To provide precise risk stratification of coronary lesions, combined near-infrared spectroscopy and intravascular ultrasound (NIRS-IVUS) was developed to integrate morphological and molecular information on plaque composition. However, there is a lack of evidence on the association between NIRS-IVUS derived findings such as maximum 4mm lipid core burden index (maxLCBI4mm) and clinical outcomes in AS patients undergoing TAVI. This registry aims to assess feasibility and safety of NIRS-IVUS imaging in the setting of routine pre-TAVI coronary angiography to improve assessment of CAD severity. METHODS: The registry is designed as a non-randomized, prospective, observational, multicenter cohort registry. Patients referred for TAVI with angiographic evidence of CAD receive NIRS-IVUS imaging and are followed up to 24 months. Enrolled patients are classified as NIRS-IVUS positive and NIRS-IVUS negative, respectively, based on their maxLCBI4mm to compare their clinical outcomes. The primary endpoint of the registry is major adverse cardiovascular events over a 24-month follow-up period. CONCLUSIONS: Identification of patients likely or unlikely to benefit from revascularization prior to TAVI represents an important unmet clinical need. This registry is designed to investigate whether NIRS-IVUS-derived atherosclerotic plaque characteristics can identify patients and lesions at risk for future adverse cardiovascular events after TAVI, in order to refine interventional decision-making in this challenging patient population.

BACKGROUND: Permanent pacemaker implantation (PPI) remains a relevant complication after transcatheter aortic valve implantation (TAVI) and its impact on outcome remains controversial. AIMS: This study aimed to analyze the effects of implantation depth on PPI at 30 days and assess its impact on outcome with the balloon-expandable Sapien 3 (S3) prosthesis. METHODS: Between 2014 and 2018, 849 patients without previous pacemaker undergoing transfemoral TAVI with the S3 were included. Prosthesis implantation depth was measured and divided into Quintiles. An ordinal logistic regression was used to assess its association with PPI, while a multivariate logistic regression was performed to identify predictors of PPI. Survival analyses were performed with the Kaplan-Meier method and a multivariable Cox regression was performed to ascertain the impact of PPI on mortality. RESULTS: Overall, incidence of PPI at 30 days was 9.7%. Implantation depth decreased consistently from a median of 6.7 mm [5.55-8.00] in 2014 to 2.7 mm [2.30-3.50] in 2018 (p < 0.001). When considering Quintiles of implantation depth, incidence of PPI was significantly higher in upper Quintiles and risk for PPI was significantly lower for the 1. Quintile compared to the 5. Quintile (OR: 0.34, 95% CI: [0.16-0.73]; p = 0.003). In the adjusted multivariable logistic regression implantation depth persisted ad independent predictor of PPI at 30 days. Patients requiring PPI at 30 days displayed significantly higher mortality at 4 years compared to patients without PPI (49.5% vs. 40.0%; log-rank = 0.022). In a multivariate analysis, increased logistic EuroScore, diabetes mellitus, and history of atrial fibrillation, were independent predictors of all-cause mortality at 2 years. CONCLUSIONS: Higher prosthesis implantation relative to the virtual aortic annulus was significantly associated with reduced risk for PPI at 30 days. Patients with PPI at 30 days exhibited higher mortality during follow-up, however, only logistic EuroScore, diabetes mellitus, and history of atrial fibrillation were identified as independent predictors of mortality at 2 years.

BACKGROUND: Infective endocarditis (IE) following transcatheter aortic valve replacement (TAVR) has been associated with a dismal prognosis. However, scarce data exist on IE perivalvular extension (PEE) in such patients. METHODS: This multicenter study included 579 patients who had the diagnosis of definite IE at a median of 171 (53-421) days following TAVR. PEE was defined as the presence of an intracardiac abscess, pseudoaneurysm, or fistula. RESULTS: A total of 105 patients (18.1%) were diagnosed with PEE (perivalvular abscess, pseudoaneurysm, fistula, or a combination in 87, 7, 7, and 4 patients, respectively). A history of chronic kidney disease (adjusted odds ratio [ORadj], 2.08; 95% confidence interval [CI]: 1.27-3.41; Pâ =â .003) and IE secondary to coagulase-negative staphylococci (ORadj, 2.71; 95% CI: 1.57-4.69; Pâ <â .001) were associated with an increased risk of PEE. Surgery was performed at index IE episode in 34 patients (32.4%) with PEE (vs 15.2% in patients without PEE, Pâ <â .001). In-hospital and 2-year mortality rates among PEE-IE patients were 36.5% and 69.4%, respectively. Factors independently associated with an increased mortality were the occurrence of other complications (stroke post-TAVR, acute renal failure, septic shock) and the lack of surgery at index IE hospitalization (padjâ <â 0.05 for all). CONCLUSIONS: PEE occurred in about one-fifth of IE post-TAVR patients, with the presence of coagulase-negative staphylococci and chronic kidney disease determining an increased risk. Patients with PEE-IE exhibited high early and late mortality rates, and surgery during IE hospitalization seemed to be associated with better outcomes.

BACKGROUND: Procedural improvements combined with the contemporary clinical profile of patients undergoing transcatheter aortic valve replacement (TAVR) may have influenced the incidence and outcomes of infective endocarditis (IE) following TAVR. We aimed to determine the temporal trends, characteristics, and outcomes of IE post-TAVR. METHODS: Observational study including 552 patients presenting definite IE post-TAVR. Patients were divided in 2 groups according to the timing of TAVR (historical cohort [HC]: before 2014; contemporary cohort [CC]: after 2014). RESULTS: Overall incidence rates of IE were similar in both cohorts (CC vs HC: 5.45 vs 6.52 per 1000 person-years; Pâ =â .12), but the rate of early IE was lower in the CC (2.29 vs 4.89, Pâ <â .001). Enterococci were the most frequent microorganism. Most patients presented complicated IE ( CC: 67.7%; HC: 69.6%; Pâ =â .66), but the rate of surgical treatment remained low (CC: 20.7%; HC: 17.3%; Pâ =â .32). The CC exhibited lower rates of in-hospital acute kidney injury (35.1% vs 44.6%; Pâ =â .036) and in-hospital (26.6% vs 36.4%; Pâ =â .016) and 1-year (37.8% vs 53.5%; Pâ <â .001) mortality. Higher logistic EuroScore, Staphylococcus aureus etiology, and complications (stroke, heart failure, and acute renal failure) were associated with in-hospital mortality in multivariable analyses (Pâ <â .05 for all). CONCLUSIONS: Although overall IE incidence has remained stable, the incidence of early IE has declined in recent years. The microorganism, high rate of complications, and very low rate of surgical treatment remained similar. In-hospital and 1-year mortality rates were high but progressively decreased over time.

AIMS: Peri-procedural transcatheter valve embolization and migration (TVEM) is a rare but potentially devastating complication of transcatheter aortic valve implantation (TAVI). We sought to assess the incidence, causes, and outcome of TVEM in a large multicentre cohort. METHODS AND RESULTS: We recorded cases of peri-procedural TVEM in patients undergoing TAVI between January 2010 and December 2017 from 26 international sites. Peri-procedural TVEM occurred in 273/29 636 (0.92%) TAVI cases (age 80.8 ± 7.3 years; 53.8% female), of which 217 were to the ascending aorta and 56 to the left ventricle. The use of self-expanding or first-generation prostheses and presence of a bicuspid aortic valve were independent predictors of TVEM. Bail-out measures included repositioning attempts using snares or miscellaneous tools (41.0%), multiple valve implantations (83.2%), and conversion to surgery (19.0%). Using 1:4-propensity matching, we identified a cohort of 235 patients with TVEM (TVEMPS) and 932 patients without TVEM (non-TVEMPS). In the matched cohort, all-cause mortality was higher in TVEMPS than in non-TVEMPS at 30 days (18.6% vs. 4.9%; P < 0.001) and after 1 year (30.5% vs. 16.6%; P < 0.001). Major stroke was more frequent in TVEMPS at 30 days (10.6% vs. 2.8%; P < 0.001), but not at 1 year (4.6% vs. 1.9%; P = 0.17). The need for emergent cardiopulmonary support, major stroke at 30 days, and acute kidney injury Stages 2 and 3 increased the risk of 1-year mortality, whereas a better renal function at baseline was protective. CONCLUSION: Transcatheter valve embolization and migration occurred in approximately 1% and was associated with increased morbidity and mortality.

AIM: Psoas muscle cross-sectional area (CSA) is a proposed marker of frailty associated with mortality after transcatheter aortic valve implantation (TAVI). We assessed the impact of psoas CSA on medium-term mortality over 5 years in a large cohort, adjusted for pre-procedural variables. METHOD: This single-centre registry-derived analysis assessed 1,731 consecutive TAVI patients between 2007 and 31 April 2015 with available abdominal computed tomography scans. Sex-stratified, height-adjusted psoas CSA was measured mid-body of the fourth lumbar vertebra. Kaplan-Meier survival distributions across psoas CSA quartiles were compared. Cox and logistic regression models were used to assess baseline variables associated with the primary outcome, which was mortality within 5 years. RESULTS: Median age was 81 years (interquartile range, 77 - 85); 52.5% were women. The primary endpoint occurred in 555 patients over a mean follow-up of 775 days. Lower psoas CSA quartile patients were older, had a lower body mass index, lower creatinine clearance, and lower rates of previous cardiac surgery, with higher rates of diabetes, coronary artery disease, pacemaker, anaemia, hypoalbuminaemia, and higher European System for Cardiac Operative Risk Evaluation (EuroSCORE). Unadjusted survival by psoas CSA quartile was significantly different in men (log rank p=0.041) but not women (p=0.099). In Bonferroni-adjusted multivariate analysis, psoas CSA quartiles were not significantly associated with mortality. Hypoalbuminaemia (hazard ratio [HR], 2.10; 95% confidence interval [CI], 1.53 - 2.87 [p<0.001]) and increasing age (HR, 1.03 per year; 95% CI, 1.01 - 1.05 [p=0.002]) were associated with increased risk; female sex (HR, 0.63; 95% CI 0.51 - 0.78 [p<0.001]), and hypercholesterolaemia (HR, 0.67; 95%, CI 0.54 0.83 [p<0.001]) with reduced risk. CONCLUSIONS: Psoas CSA was not significantly associated with mortality after adjusting for pre-procedural variables. Hypoalbuminaemia, sex, hypercholesterolaemia, and age were significantly associated with mortality after TAVI.

OBJECTIVES: To evaluate 1-year outcome using the ACURATE neo (Symetis S.A., a Boston Scientific Company, Ecublens, Switzerland) according to the updated Valve Academic Research Consortium (VARC-2) with emphasis on the composite endpoints "clinical efficacy after 30 days" and "time-related valve safety". BACKGROUND: Initial reports on the clinical performance of patients treated with the ACURATE neo are promising; however, information regarding one-year outcome is scarce, especially with regard to the composite endpoints proposed by the VARC-2. METHODS: One hundred and fifty one consecutive patients undergoing transfemoral transcatheter aortic valve replacement (TAVR) with the ACURATE neo for severe aortic valve stenosis were enrolled. Data were prospectively collected and event rates during follow-up were calculated as the Kaplan-Meier estimates. RESULTS: Mean age was 81.1 ± 5.9 years and 49.7% (75/151) were female with a median logistic EuroScore of 13.8% [8.2-20.5]. Device success was achieved in 88.1% (133/151) and procedure related mortality was 0.7% (1/151). At one-year, all-cause mortality was 3.3% (5/151), while permanent pacemaker implantation occurred in 12.7% (19/151) of patients. The "clinical efficacy after 30 days" was observed in 24.8% (37/151), where the main contributor was symptom worsening in 14.8% (22/151) of cases. "Time-related valve safety" occurred in 22.0% (33/151) with structural valve deterioration as main contributor in 10.7% (16/151) of cases. CONCLUSIONS: Using the ACURATE neo, we found a favorable safety profile with low all-cause mortality at 1 year. The reported VARC-2 defined composite endpoints at 1 year reveal low rates of "clinical efficacy after 30 days" and "time-related valve safety".

BACKGROUND: Although the incidence of periprocedural complications has decreased in transcatheter aortic valve implantation (TAVI), life-threatening complications occur and emergency veno-arterial extracorporeal membrane oxygenation (vaECMO) can provide immediate circulatory stabilization. We report our two-center experience of vaECMO during life-threatening complications in TAVI. METHODS: From January 2010 to December 2015, 1,810 consecutive patients underwent TAVI at two centers. Clinical characteristics, type of complication, outcome and temporal trends in the requirement of emergency vaECMO were evaluated. RESULTS: Life-threatening complications requiring vaECMO occurred in 1.8% of cases (33 patients; 22 transfemoral, 11 transapical). Indications for vaECMO were ventricular rupture (30%, 10/33), low output (15%, 5/33), bleeding (12%, 4/33), coronary artery impairment (9%, 3/33), ventricular arrhythmias (6%, 2/33), severe aortic regurgitation (6%, 2/33), aortic annular rupture (6%, 2/33), and aortic dissection (3%, 1/33). In 4 cases, no definite cause for hemodynamic instability was identified. Conversion to open heart surgery was necessary in 42% of patients (14/33). Percutaneous coronary intervention was performed in all cases with coronary artery impairment (9%, 3/33). Patients with severe aortic regurgitation (6%, 2/33) underwent emergency valve-in-valve implantation. Other patients received, in addition to vaECMO support conservative treatment (42%, 14/33). In-hospital mortality and 30-day mortality were 46% (15/33). Of patients discharged, 67% (12/18) had no neurological impairment, whereas mild and severe neurological impairment was found in 11% (2/18) and 22% (4/18), respectively. From 2010 to 2015, with increasing procedures (from n = 43 to n = 553) requirement of vaECMO decreased from 9.3% to 0.9% (P for the trend <0.001). CONCLUSION: Over a 6-year period, need for emergency vaECMO during TAVI significantly decreased over time. Despite high in-hospital mortality, vaECMO represents a feasible strategy for hemodynamic support in case of life-threatening complications.

PURPOSE: Elevated carbohydrate antigen 125 (CA125) predicts adverse outcome after transcatheter aortic valve implantation (TAVI). While known underlying pathophysiological mechanisms of elevated CA125 include serosal effusions and inflammatory stimuli, clinical determinants associated with elevated CA125 in patients referred for TAVI remain unknown. Therefore, we investigated clinical, laboratory and echocardiographic determinants of elevated CA125 in patients with severe aortic valve stenosis referred for TAVI. METHODS: This study includes 650 patients with severe aortic stenosis referred for TAVI. Baseline CA125 was determined by an immunoassay and dichotomized (elevated versus normal) based on the manufacturer cutoff value (>35 U/mL). RESULTS: CA125 elevation was present in 28% (181/650). Patients with elevated CA125 had an overall worse clinical profile and were more symptomatic with a higher rate of NYHA class III/IV (80% versus 58%; p < 0.001). In a multivariate analysis, independent predictors of elevated CA125 were New York Heart Association (NYHA) class, baseline hemoglobin, C-reactive protein (CRP), left ventricular ejection fraction and severe tricuspid regurgitation. CONCLUSION: Elevated CA125 levels in patients referred for TAVI summarize a subset of patients with an overall worse clinical profile who are more symptomatic.

OBJECTIVES: Systemic inflammatory response syndrome (SIRS) is a common finding after cardiovascular interventions. Data on the incidence of SIRS and its impact on outcome in patients undergoing transcatheter edge-to-edge mitral valve repair (MV-TEER) for mitral regurgitation (MR) is lacking. METHODS: From January 2013 to December 2020, 373 patients with moderate or severe MR undergoing MV-TEER were included. SIRS was defined as at least two of the following criteria within 48 h after the procedure: leucocyte count > 12.0 or < 4.0 × 109/l, respiratory rate > 20 breaths per minute or PaCO2 ≤ 4.3 kPa/32 mmHg, heart rate > 90 bpm and temperature > 38.0 °C or < 36.0 °C. The primary endpoint was 3-years all-cause mortality. RESULTS: SIRS was observed in 49.6% (185/373) of patients. Patients who developed SIRS presented more frequently with NYHA III/IV at baseline [SIRS: 82.4% (149/185) vs. no SIRS: 79.0% (147/188); p = 0.029]. Patients who developed SIRS spent more days on ICU (p < 0.001) and overall length of stay was longer (p < 0.001). Relevant residual MR, defined as MR ≥ III in-hospital, was present more often in patients who developed SIRS [SIRS: 11.3% (20/177) vs. no SIRS: 3.93% (7/178), p = 0.036]. At 3 years, all-cause mortality in the entire population was 33.5% (125/373) with an increased all-cause mortality in patients with SIRS compared to patients without SIRS (HR 1.49, [CI 95% 1.04, 2.13]; p = 0.0264). In the multivariate analysis development of SIRS (HR 1.479 [CI 95% 1.016, 2.154]; p = 0.041) was identified as predictor for 3-years all-cause mortality. CONCLUSIONS: SIRS is a common finding after MV-TEER occurring in approximately half of patients. SIRS after MV-TEER was associated with a longer in-hospital stay. In addition, we observed an increased 3-years all-cause mortality in patients with SIRS.

Background: The interplay between the right ventricle and the pulmonary artery, known as right ventricular to pulmonary artery (RV-PA) coupling, is crucial for assessing right ventricular systolic function against the afterload from the pulmonary circulation. Pulmonary artery pressure levels are ideally measured by right heart catheterization. Yet, echocardiography represents the most utilized method for evaluating pulmonary artery pressure levels, albeit with limitations in accuracy. This study therefore aims to evaluate the prognostic significance of right ventricular to pulmonary artery (RV-PA) coupling expressed as tricuspid annular plane systolic excursion (TAPSE) related to systolic pulmonary artery pressure (sPAP) levels measured by right heart catheterization (TAPSE/sPAPinvasive) or estimated by transthoracic echocardiography (TAPSE/sPAPechocardiography) in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). Methods: Using data from a bicentric registry, this study compares TAPSE/sPAPinvasive vs. TAPSE/sPAPechocardiography in predicting 1-year all-cause mortality after TAVR. Results: Among 333 patients with complete echocardiography and right heart catheterization data obtained before TAVR, their mean age was 79.8 ± 6.74 years, 39.6% were female, and general 1-year survival was 89.8%. sPAPinvasive and sPAPechocardiography showed only moderate correlation (Pearson correlation coefficient R: 0.53, p value: <0.0001). TAPSE/sPAPinvasive was superior to TAPSE/sPAPechocardiography in predicting 1-year all-cause mortality after TAVR (area under the curve: 0.662 vs. 0.569, p value: 0.025). Patients with reduced TAPSE/sPAPinvasive levels (< 0.365 mm/mmHg) evidenced significantly lower 1-year survival rates than patients with preserved TAPSE/sPAPinvasive levels (81.8 vs. 93.6%, p value: 0.001; hazard ratio for 1-year mortality: 3.09 [95% confidence interval: 1.55-6.17]). Echocardiographic follow-up data revealed that patients with reduced RV-PA coupling suffer from persistent right ventricular dysfunction (TAPSE: 16.6 ± 4.05 mm vs. 21.6 ± 4.81 mm in patients with preserved RV-PA coupling) and severe tricuspid regurgitation (diagnosed in 19.7 vs. 6.58% in patients with preserved RV-PA coupling). Conclusions: RV-PA coupling expressed as TAPSE/sPAPinvasive can refine stratification of severe aortic stenosis patients into low-risk and high-risk cohorts for mortality after TAVR. Moreover, it can help to anticipate persistent extra-aortic valve cardiac damage, which will demand further treatment.
RESUMO
BACKGROUND: New-generation self-expanding transcatheter aortic heart valves (THV) were designed to overcome technical constraints of their preceding generations. We sought to compare the efficacy and safety of the self-expanding ACURATE neo2 (Neo2) versus Evolut PRO (PRO) devices. METHODS: Seven hundred nine patients undergoing transfemoral transcatheter aortic valve implantation (TAVI) with either Neo2 (n = 496) or PRO (n = 213) were included. Propensity score matching (PSM) was performed to account for differences in baseline characteristics. In-hospital and 30-day clinical outcomes were evaluated according to Valve Academic Research Consortium-3 criteria. RESULTS: Baseline characteristics were comparable between both groups after PSM (Neo2: n = 155, Evolut Pro: n = 155). Technical success rates were high in both groups (Neo2: 94.8% vs PRO: 97.4%; p = 0.239). Need for permanent pacemaker implantation was less frequent with Neo2 compared with PRO (7.5% vs 20.6%; p = 0.002), whereas major vascular complications were more frequent with Neo2 (Neo2: 11.6% vs PRO: 4.5%; p = 0.022). Intended valve performance at discharge was high in both groups without relevant differences among groups (Neo2: 97.4% vs. 95.3%; p = 0.328). CONCLUSIONS: Short-term outcomes after TAVI using latest-generation self-expanding THV were excellent, with overall low rates of adverse events. However, Neo2 was associated with lower pacemaker rates and reduced the prevalence of moderate-severe paravalvular leakage. Transprosthetic gradients after TAVI were higher with Neo2 compared with PRO.

BACKGROUND: ACURATE neo2 (Neo2) implantation is performed after systematic Balloon Aortic Valvuloplasty (BAV) in most patients. No reports exist about the feasibility and safety of direct Neo2 transcatheter aortic valve implantation (TAVI) in comparison to the standard practice. AIM: We aimed to identify the patients' baseline anatomical characteristics, procedural, and early post-procedural outcomes in patients treated using Neo2 with and without BAV. METHODOLOGY: This is a retrospective multicentre analysis of 499 patients with severe aortic stenosis who underwent TAVI using Neo2. The comparison was done according to the performance or omission of BAV. Echocardiography and computed tomography were analysed by an independent Core Lab. Propensity score matching (PSM) was performed based on the annular diameter and AV calcium volume, which identified 84 matched pairs. RESULTS: Among the cohort included, 391 (78%) patients received BAV (BAV-yes) and 108 (22%) were not attempted (BAV-no or Direct TAVI). Patients in BAV-no cohort had smaller annular diameter (22.6 vs 23.4 mm; p < 0.001) and lower calcium volume (163 vs 581 mm3; p < 0.001) compared to BAV-yes cohort. In the matched cohort, VARC-3 device technical success was similar (95%) and all other outcome measures were statistically comparable between cohorts. CONCLUSION: Direct TAVI using ACURATEneo2 without pre-TAVI balloon aortic valvuloplasty in patients with mild or less valve calcifications might be feasible and associated with comparable early outcomes compared to patients with similar anatomical features undergoing systematic balloon valvuloplasty.

BACKGROUND: No comparative data exist with the latest generation self-expanding ACURATE neo2 (Neo2) and the balloon-expandable SAPIEN 3 Ultra (Ultra) transcatheter heart valves (THV). AIMS: We aimed to compare the outcomes after transcatheter aortic valve implantation (TAVI) using the Neo2 and the Ultra THV. METHODS: A total of 1,356 patients at 4 centres were treated either with the Neo2 (n=608) or the Ultra (n=748). The primary endpoint was device success according to the latest Valve Academic Research Consortium definitions. The association of the THV used and the primary endpoint was assessed using inverse probability treatment weighting (IPTW) and 1:1 propensity score matching (PSM), which identified 472 matched pairs. Results: After PSM, there were no relevant differences between the groups. While rates of moderate to severe paravalvular leakage (PVL) were overall low (0.6% vs 1.1%; p=0.725), elevated transvalvular gradients (≥20 mmHg) were less frequent with the Neo2 (2.4% vs 7.7%; p<0.001), which translated into a significantly higher rate of device success with the Neo2 compared with the Ultra (91.9% vs 85.0%; p<0.001). Consistently, the Neo2 was associated with higher rates of device success in the IPTW analysis (odds ratio [OR] 1.961, 95% confidence interval [CI]: 1.269-3.031; p=0.002). Rates of mild PVL were significantly lower with the Ultra compared with the Neo2 (20.0% vs 32.8%; p<0.001). Clinical events at 30 days were comparable between the 2 groups. CONCLUSIONS: Short-term outcomes after TAVI using the Neo2 or Ultra THV were excellent and, overall, comparable. However, transvalvular gradients were lower with the Neo2, which translated into higher rates of device success. Rates of mild PVL were significantly lower with the Ultra THV.

BACKGROUND: Data on systemic inflammatory response syndrome (SIRS) after transcatheter aortic valve implantation (TAVI) are scarce and limited to small cohorts. We aimed to investigate its incidence and mid-term impact in a large cohort of TAVI patients. METHODS: From January 2018 to December 2020, 717 patients with severe aortic valve stenosis undergoing TAVI were included. SIRS was defined as fulfilling at least two of the following criteria within 48 h from the procedure: leucocyte count >12.0 or <4.0 × 109/l, respiratory rate > 20 breaths per minute or PaCO2 ≤ 4.3 kPa/32 mmHg, heart rate > 90 beats per minute and temperature > 38.0 °C or <36.0 °C. Clinical endpoints were 1-year rehospitalization for chronic heart failure (CHF) and 2-years all-cause mortality. Event rates during follow-up were calculated as Kaplan-Meier estimates. RESULTS: SIRS developed in 56.3 % (404/717) of patients after TAVI. SIRS occurred more frequently in patients with post-dilatation (SIRS 34.7 % (140/404) vs. no SIRS 23.3 % (73/313); p < 0.001) and major vascular complications (SIRS 16.1 % (65/404) vs. no SIRS 8.6 % (27/313); p = 0.004). Further, ICU days were more in patients who developed SIRS (SIRS 1.56 ± 1.50 days vs. no SIRS 1.22 ± 1.02 days; p = 0.001). At 2-years, all-cause mortality in the entire population was 23.9 %. However, there was no difference in CHF at 1-year (5.9 % vs. 4.1 %; log-rank = 0.347) nor in all-cause mortality at 2-years (22.0 % vs. 26.2 %; log-rank = 0.690) between the groups. CONCLUSIONS: SIRS is a common finding after TAVI, which may prolong hospital stay but is without effect on mortality during 2-years follow-up.
