ABSTRACT
Aims: A majority of acute coronary syndromes (ACS) present without typical ST elevation. One-third of non-ST-elevation myocardial infarction (NSTEMI) patients have an acutely occluded culprit coronary artery [occlusion myocardial infarction (OMI)], leading to poor outcomes due to delayed identification and invasive management. In this study, we sought to develop a versatile artificial intelligence (AI) model detecting acute OMI on single-standard 12-lead electrocardiograms (ECGs) and compare its performance with existing state-of-the-art diagnostic criteria. Methods and results: An AI model was developed using 18 616 ECGs from 10 543 patients with suspected ACS from an international database with clinically validated outcomes. The model was evaluated in an international cohort and compared with STEMI criteria and ECG experts in detecting OMI. The primary outcome of OMI was an acutely occluded or flow-limiting culprit artery requiring emergent revascularization. In the overall test set of 3254 ECGs from 2222 patients (age 62 ± 14 years, 67% males, 21.6% OMI), the AI model achieved an area under the curve of 0.938 [95% confidence interval (CI): 0.924-0.951] in identifying the primary OMI outcome, with superior performance [accuracy 90.9% (95% CI: 89.7-92.0), sensitivity 80.6% (95% CI: 76.8-84.0), and specificity 93.7 (95% CI: 92.6-94.8)] compared with STEMI criteria [accuracy 83.6% (95% CI: 82.1-85.1), sensitivity 32.5% (95% CI: 28.4-36.6), and specificity 97.7% (95% CI: 97.0-98.3)] and with similar performance compared with ECG experts [accuracy 90.8% (95% CI: 89.5-91.9), sensitivity 73.0% (95% CI: 68.7-77.0), and specificity 95.7% (95% CI: 94.7-96.6)]. Conclusion: The present novel ECG AI model demonstrates superior accuracy to detect acute OMI when compared with STEMI criteria. This suggests its potential to improve ACS triage, ensuring appropriate and timely referral for immediate revascularization.
ABSTRACT
OBJECTIVE: Management of patients with severe aortic stenosis (AS) may differ according to the patient sex. This study aimed to describe patterns of aortic valve replacement (AVR) for severe AS across Europe, including stratification by sex. METHODS: Procedure volume data for surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI) for six years (2015-2020) were extracted from national databases for Austria, Czech Republic, Denmark, England, Finland, France, Germany, Norway, Poland, Spain, Sweden, and Switzerland and stratified by sex. Patients per million population (PPM) undergoing AVR per year were calculated using population estimates from Eurostat. RESULTS: Between 2015 and 2019, AVR procedures grew at an average annual rate of 3.9%. In 2020, the average total PPM undergoing AVR across all countries was 339, with 51% of procedures being TAVI and 49% SAVR. AVR PPM varied widely between countries, with the highest and lowest in Germany and Poland, respectively. The average total PPM was higher for men than women (423 vs. 258), but a higher proportion of women (62%) than men (44%) received TAVI. The proportion of TAVI among total AVR procedures increased with age, with an overall average of 96% of men and 98% of women aged ≥85 years receiving TAVI; however, adoption of TAVI varied by country. CONCLUSIONS: The analysis of temporal trends in the adoption of TAVI vs. SAVR across Europe showed significant variations. Despite the higher use of TAVI vs. SAVR in women, overall rates of AV intervention in women were lower compared to men.

BACKGROUND: Dialysis is a rare but serious complication after transcatheter aortic valve replacement. We analyzed the large multicenter TRITAVI (transfusion requirements in transcatheter aortic valve implantation) registry in order to develop and validate a clinical score assessing this risk. METHODS AND RESULTS: A total of 10 071 consecutive patients were enrolled in 19 European centers. Patients were randomly assigned (2:1) to a derivation and validation cohort. Two scores were developed, 1 including only preprocedural variables (TRITAVIpre) and 1 also including procedural variables (TRITAVIpost). In the 6714 patients of the derivation cohort (age 82±6 years, 48% men), preprocedural factors independently associated with dialysis and included in the TRITAVIpre score were male sex, diabetes, prior coronary artery bypass graft, anemia, nonfemoral access, and creatinine clearance <30 mL/min per m2. Additional independent predictors among procedural features were volume of contrast, need for transfusion, and major vascular complications. Both scores showed a good discrimination power for identifying risk for dialysis with C-statistic 0.78 for TRITAVIpre and C-statistic 0.88 for TRITAVIpost score. Need for dialysis increased from the lowest to the highest of 3 risk score groups (from 0.3% to 3.9% for TRITAVIpre score and from 0.1% to 6.2% for TRITAVIpost score). Analysis of the 3357 patients of the validation cohort (age 82±7 years, 48% men) confirmed the good discrimination power of both scores (C-statistic 0.80 for TRITAVIpre and 0.81 for TRITAVIpost score). Need for dialysis was associated with a significant increase in 1-year mortality (from 6.9% to 54.4%; P=0.0001). CONCLUSIONS: A simple preprocedural clinical score can help predict the risk of dialysis after transcatheter aortic valve replacement.

AIMS: Remnant cholesterol and very low-density lipoprotein cholesterol (VLDL-C) are increasingly recognized risk factors for atherosclerotic disease with few therapeutic options. Angiopoietin-like 3 (ANGPTL3), a key protein in the metabolism of triglyceride-rich lipoproteins, is a promising target. METHODS AND RESULTS: TRANSLATE-TIMI 70 was a double-blind, placebo-controlled randomized trial testing seven dose regimens of vupanorsen, an antisense oligonucleotide against ANGPTL3, in adults with non-HDL-C ≥ 100â mg/dL and triglycerides 150-500â mg/dL. The primary endpoint of this analysis was percentage change in remnant cholesterol (total cholesterol minus directly measured LDL-C minus HDL-C) and VLDL-C (directly measured) over 24 weeks. Two hundred eighty-six patients were enrolled, with a median age of 64 years and 44% female. Median baseline remnant cholesterol and VLDL-C were 42 and 31â mg/dL, respectively (reference: <30â mg/dL). Vupanorsen lowered remnant cholesterol by 42-59% at 24 weeks over placebo (P < 0.001), achieving a median level of 18â mg/dL at the highest dose. Over the same period, VLDL-C was reduced by 52-67% over placebo (P < 0.001), with a median achieved level of 2.5â mg/dL at the highest dose. The effect of vupanorsen on remnant cholesterol and VLDL-C reduction was dose-dependent and directly associated with the degree of ANGPTL3 inhibition: at 90% ANGPTL3 reduction, there was a 61% and 81% decrease in remnant cholesterol and VLDL-C, respectively. CONCLUSION: Inhibition of ANGPTL3 protein synthesis significantly lowered remnant cholesterol and VLDL-C in patients with hypertriglyceridaemia. The magnitude of reduction was associated with the degree of ANGPTL3 inhibition. These findings support ANGPTL3 inhibition as a promising target for lowering cholesterol on triglyceride-rich lipoproteins.
In this randomized controlled trial of 286 participants with elevated triglycerides, treatment with vupanorsen, an ANGPTL3 inhibitor, lowered remnant cholesterol by up to 59% and VLDL cholesterol by up to 67% over placebo. The effect of the treatment was sustained throughout 24 weeks and consistent across key patient subgroups. ANGPTL3 inhibition may be a promising approach to treat patients with elevated triglycerides.

BACKGROUND: Patients with severe aortic stenosis (AS) frequently present with concomitant obstructive coronary artery disease (CAD). In those, current guidelines recommend combined coronary artery bypass grafting (CABG) and surgical aortic valve replacement (SAVR) as the preferred treatment option, although this surgical approach is associated with a high rate of clinical events. Combined transcatheter aortic valve implantation (TAVI) and percutaneous coronary intervention (PCI) with or without FFR have evolved as a valid alternative for cardiac surgery in patients with AS and multivessel or advanced CAD. To date, no dedicated trial has prospectively evaluated the outcomes of a percutaneous versus surgical treatment for patients with both severe AS and CAD. AIMS: To investigate whether fractional-flow reserve (FFR)-guided PCI and TAVI is noninferior to combined CABG and SAVR for the treatment of severe AS and multivessel or advanced CAD. METHODS: The Transcatheter Valve and Vessels (TCW) trial (clinicaltrial.gov: NCT03424941) is a prospective, randomized, controlled, open label, international trial. Patients ≥ 70 years with severe AS and multivessel (≥ 2 vessels) or advanced CAD, deemed feasible by the heart team for both; a full percutaneous or surgical treatment, will be randomised in a 1:1 fashion to either FFR-guided PCI followed by TAVI (intervention arm) vs. CABG and SAVR (control arm). The primary endpoint is a patient-oriented composite of all-cause mortality, myocardial infarction, disabling stroke, unscheduled clinically-driven target vessel revascularization, valve reintervention, and life threatening or disabling bleeding at 1 year. The TCW trial is powered for noninferiority, and if met, superiority will be tested. Assuming a primary endpoint rate of 30% in the CABG-SAVR arm, with a significance level α of 5%, a noninferiority limit delta of 15% and a loss to follow-up of 2%, a total of 328 patients are needed to obtain a power of 90%. The primary endpoint analysis is performed on an intention-to-treat basis. SUMMARY: The TCW Trial is the first prospective randomized trial that will study if a less invasive percutaneous treatment for severe AS and concomitant advanced CAD (i.e., FFR-guided PCI-TAVI) is noninferior to the guidelines recommended approach (CABG-SAVR).

BACKGROUND: Angiopoietin-like protein 3 (ANGPTL3) is a novel therapeutic target for hyperlipidemia. Vupanorsen, an antisense oligonucleotide targeting ANGPTL3, reduced triglycerides up to 57% in a phase 2b trial, but caused dose-dependent increases in hepatic fat fraction (HFF). OBJECTIVE: To determine the degree of HFF progression with escalating doses of vupanorsen, differential HFF increases in key patient subgroups, and the correlation between changes in HFF and liver enzymes. METHODS: TRANSLATE-TIMI 70 was a randomized, placebo-controlled trial testing 7 dosing regimens of vupanorsen in 286 adults with hyperlipidemia. A total of 227 patients had HFF measured at baseline and 24 weeks and were included in this analysis. RESULTS: The median HFF at baseline was 8.5%. Vupanorsen led to dose-dependent relative increases in HFF of up to 76% at 24 weeks (p < 0.001), corresponding to an absolute increase of up to 7.0% at the highest dose (p < 0.001). Increases in HFF were numerically greater in patients who had elevated baseline HFF, body mass index, triglycerides, or diabetes. Vupanorsen also increased liver enzymes in a dose-dependent manner, and changes in HFF were moderately positively correlated with changes in aspartate transaminase (AST) (rho = 0.49, p < 0.001) and alanine transaminase (ALT) (rho = 0.50, p < 0.001). CONCLUSION: Vupanorsen, an inhibitor of ANGPTL3 protein synthesis, caused dose-dependent increases in HFF. Increases in HFF were only moderately correlated with elevations in AST and ALT, suggesting that liver enzymes are an imperfect indicator to detect increases in hepatic fat. These results highlight the need to monitor HFF in clinical trials of therapies targeting intracellular ANGPTL3 inhibition, especially those that are targeted to the liver.

Extending the indication of transcatheter aortic valve replacement (TAVR) to younger and lower-risk patients naturally results in longer life expectancy and survival rates after the intervention. The longer life expectancy of these patients leads to an increased possibility of future acute coronary events, necessitating the development of effective and appropriate treatment strategies. Acute coronary syndromes (ACS) in patients with previous TAVR procedures present with modified clinical characteristics when compared to the non-TAVR population. In populations with prior TAVR procedures, plaque rupture remains the main cause of ACS. However, unlike the non-TAVR population, there is an increased frequency of nonatherotrombotic mechanisms, like emboli and mechanical obstruction of coronary ostia by valve components. The main observation related to the treatment of ACS TAVR patients is the significantly lower percentage of patients undergoing invasive management. Furthermore, ACS in TAVR patients is associated with poor prognosis, higher long-term mortality rates, and higher incidence of MACE. It is surprising that considering this significant and increasingly recognized issue, there are only a few studies that have investigated ACS after TAVR. The scope of the present review is to address available data about ACS following TAVR, focusing on incidence, timing, mechanism, and causes. We also examined current knowledge regarding optimal invasive treatment and analyzed short and long-term clinical outcomes.

BACKGROUND: A significant number of patients with severe mitral regurgitation (MR) are not suitable for either surgical or transcatheter edge-to-edge repair because of high surgical risk or inappropriate mitral valve anatomy. OBJECTIVES: The aim of this study was to evaluate the HighLife Trans-Septal Mitral Valve Replacement (TSMVR) system in patients with symptomatic MR and high surgical risk. METHODS: This prospective, multicenter, nonrandomized feasibility study evaluated the safety and performance of the HighLife TSMVR system in patients with moderate to severe or severe symptomatic MR during 1-year follow-up. Echocardiographic data were assessed at an independent core laboratory. RESULTS: A total of 30 patients (mean age 75.6 years, 27% women, median Society of Thoracic Surgeons score 5.5%) with severe MR (90% with secondary MR, median left ventricular ejection fraction 43%) were treated at 13 sites. In 27 of the 30 patients, the HighLife TSMVR system was implanted successfully (technical success rate 90%). Device success at 30 days was 83%. After 1 year, 5 patients (17%) had died. None of the patients who underwent implantation required mitral valve reintervention. All patients who underwent implantation had no or trace (78%) or mild (22%) MR, the mean gradient of the HighLife valve was 5.1 mm Hg, and there were no signs of left ventricular outflow tract obstruction (mean gradient 2.0 mm Hg). CONCLUSIONS: The 1-year results from the HighLife TSMVR feasibility study demonstrate a high technical success rate, excellent valve function, no left ventricular outflow tract obstruction, and no need for mitral valve reintervention. Additional patient outcomes and longer follow-up are needed to confirm these findings.

Background: Temporal trends of the impact of social determinants on cardiovascular outcomes of cancer patients has not been previously studied. Objectives: This study examined social disparities in cardiovascular mortality of people with and without cancer in the US population between 1999 and 2019. Methods: Primary cardiovascular deaths were identified from the Multiple Cause of Death database and grouped by cancer status. The cancer cohort was subcategorized into breast, lung, prostate, colorectal, and haematological. The number of cardiovascular deaths, crude cardiovascular mortality rate, cardiovascular age-adjusted mortality rate (AAMR), and percentage change in cardiovascular AAMR were calculated by cancer status and cancer type, and stratified by sex, race, ethnicity, and urban-rural setting. Results: 17.9 million cardiovascular deaths were analysed. Of these, 572,222 occurred in patients with a record of cancer. The cancer cohort were older and included more men and White racial groups. Regardless of cancer status, cardiovascular AAMR was higher in men, rural settings, and Black or African American races. Cardiovascular AAMR declined over time, with greater reduction in those with cancer (-51.6% vs -38.3%); the greatest reductions were in colorectal (-68.4%), prostate (-60.0%), and breast (-58.8%) cancers. Sex, race, and ethnic disparities reduced over time, with greater narrowing in the cancer cohort. There was increase in urban-rural disparities, which appeared greater in those with cancer. Conclusions: While most social disparities narrowed over time, urban-rural disparities widened, with greater increase in those with cancer. Healthcare plans should incorporate strategies for reduction of health inequality equitable access to cardio-oncology services.
ABSTRACT
Over the last decades, we have witnessed considerable improvements in diagnostics and risk stratification of patients with significant aortic stenosis (AS), paralleled by advances in operative and anesthetic techniques. In addition, accumulating evidence points to the potential benefit of early valve replacement in such patients prior to the onset of symptoms. In parallel, interventional randomized trials have proven the benefit of transcatheter aortic valve replacement in comparison to a surgical approach to valve replacement over a broad risk spectrum in symptomatic patients with AS. This article reviews contemporary management approaches and scrutinizes open questions regarding timing and mode of intervention in asymptomatic patients with severe AS. We also discuss the challenges surrounding the management of symptomatic patients with moderate AS as well as emerging dilemmas related to the concept of a life-long treatment strategy for patients with AS.
ABSTRACT
INTRODUCTION: The management of patients with severe aortic stenosis may differ according to patients' age. The aim of this analysis was to describe patterns of aortic valve replacement (AVR) use in European countries stratified by age. METHODS: Procedure volume data for AVR, including surgical aortic valve replacement (sAVR) and transcatheter aortic valve implantation (TAVI), for the years 2015-2020 were obtained from national databases for twelve European countries (Austria, the Czech Republic, Denmark, England, Finland, France, Germany, Norway, Poland, Spain, Sweden, and Switzerland). Procedure volumes were reported by patient age (<50 years, 5-year age groups between 50 and 85 years, and ≥85 years). Patients per million (PPM) population undergoing AVR each year were calculated using population estimates from Eurostat. RESULTS: AVR PPM varied widely between countries, from 508 PPM in Germany to 174 PPM in Poland in 2020. TAVI rates ranged from 61% in Switzerland and Finland to 25% in Poland. AVR PPM increased with age to a peak at 80-84 years, after which it decreased again. AVR procedures increased from 2015 to 2019 at an average annual rate of 3.9%. AVR increased more substantially in people aged ≥80 years than in younger age groups; these older age groups accounted for 30% of all AVR procedures in 2015 and 35% in 2019. TAVI accounted for an increasing proportion of all AVR procedures as patient age increased; an overall average of 96% of males and 98% of females aged ≥85 years received TAVI as the treatment modality, although adoption of TAVI differed between countries. CONCLUSIONS: There is considerable variation in the rates of AVR use and the adoption of TAVI versus sAVR between European countries. The use of TAVI has increased in recent years, particularly for older patients.

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.
ABSTRACT
AIMS: To assess processes of care and clinical outcomes in cancer patients with ST elevation myocardial infarction (STEMI) according to cancer type. METHODS AND RESULTS: This is a national population-based study of patients admitted with STEMI in the UK between January 2005 and March 2019. Data were obtained from the National Heart Attack Myocardial Infarction National Audit Project (MINAP) registry and the Hospital Episode Statistics registry. We identified 353 448 STEMI-indexed admissions between 2005 and 2019. Of those, 8581 (2.4%) had active cancer. Prostate cancer (29% of STEMI patients with cancer) was the most common cancer followed by haematologic malignancies (14%) and lung cancer (13%). Cancer patients were less likely to receive invasive coronary revascularization (60.0% vs. 71.6%, P < 0.001] and had higher in-hospital death [odd ratio (OR) 1.39, 95% confidence interval (CI) 1.25-1.54] and bleeding (OR 1.23, 95% CI 1.03-1.46). Cancer patients had higher mortality at 30 days (HR 2.39, 95% CI 2.19-2.62) and 1 year (HR 3.73, 95% CI 3.58-3.89). Lung cancer was the cancer associated with the highest risk of death in the hospital (OR 1.75, 95% CI 1.39-2.22) and at 1 year (OR 8.08, 95% CI 7.44-8.78). Colon cancer (OR 1.98, 95% CI 1.24-3.14) was the main cancer associated with major bleeding. All common cancer types were associated with higher mortality at 1 year. Cardiovascular death (62%) was the main cause of death in the first 30 days, while cancer (52%) was the main cause of death within 1 year. CONCLUSION: STEMI patients with cancer have a higher risk of short- and long-term mortality, particularly lung cancer. Colon cancer is the main cancer associated with major bleeding. Cardiovascular disease was the main cause of death in the first month, whereas cancer was the main cause of death within 1 year.

AIMS: The aim of the SCIENCE trial was to investigate whether a single treatment with direct intramyocardial injections of adipose tissue-derived mesenchymal stromal cells (CSCC_ASCs) was safe and improved cardiac function in patients with chronic ischaemic heart failure with reduced ejection fraction (HFrEF). METHODS AND RESULTS: The study was a European multicentre, double-blind, placebo-controlled phase II trial using allogeneic CSCC_ASCs from healthy donors or placebo (2:1 randomization). Main inclusion criteria were New York Heart Association (NYHA) class II-III, left ventricular ejection fraction (LVEF) <45%, and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels >300 pg/ml. CSCC_ASCs or placebo (isotonic saline) were injected directly into viable myocardium. The primary endpoint was change in left ventricular end-systolic volume (LVESV) at 6-month follow-up measured by echocardiography. A total of 133 symptomatic HFrEF patients were included. The treatment was safe without any drug-related severe adverse events or difference in cardiac-related adverse events during a 3-year follow-up period. There were no significant differences between groups during follow-up in LVESV (0.3 ± 5.0 ml, p = 0.945), nor in secondary endpoints of left ventricular end-diastolic volume (-2.0 ± 6.0 ml, p = 0.736) and LVEF (-1.6 ± 1.0%, p = 0.119). The NYHA class improved slightly within the first year in both groups without any difference between groups. There were no changes in 6-min walk test, NT-proBNP, C-reactive protein or quality of life the first year in any groups. CONCLUSION: The SCIENCE trial demonstrated safety of intramyocardial allogeneic CSCC_ASC therapy in patients with chronic HFrEF. However, it was not possible to improve the pre-defined endpoints and induce restoration of cardiac function or clinical symptoms.

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: A severe prosthesis-patient mismatch (PPM) is associated with adverse outcomes following transcatheter aortic valve replacement (TAVR) for de novo aortic stenosis or a failed surgical bioprosthesis. The impact of severe PPM in patients undergoing TAV-in-TAVR is unknown. Aim: We sought to investigate the incidence and 1-year outcomes of different grades of PPM in patients undergoing TAV-in-TAVR. Materials and methods: The TRANSIT-PPM is an international registry, including cases of degenerated TAVR treated with a second TAVR. PPM severity, as well as in-hospital, 30-day, and 1-year outcomes were defined according to the Valve Academic Research Consortium-3 (VARC-3) criteria. Results: Among 28 centers, 155 patients were included. Severe PPM was found in 6.5% of patients, whereas moderate PPM was found in 14.2% of patients. The rate of severe PPM was higher in patients who underwent TAV-in-TAVR with a second supra-annular self-expanding (S-SE) TAVR (10%, p = 0.04). Specifically, the rate of severe PPM was significantly higher among cases of a SE TAVR implanted into a balloon-expandable (BE) device (19%, p = 0.003). At 1-year follow-up, the rate of all-cause mortality, and the rate of patients in the New York Heart Association (NYHA) class III/IV were significantly higher in the cohort of patients with severe PPM (p = 0.016 and p = 0.0001, respectively). Almost all the patients with a severe PPM after the first TAVR had a failed < 23 mm BE transcatheter heart valve (THV): the treatment with an S-SE resolved the severe PPM in the majority of the cases. Conclusion: After TAV-in-TAVR, in a fifth of the cases, a moderate or severe PPM occurred. A severe PPM is associated with an increased 1-year all-cause mortality.
