RESUMO
AIMS: Telemonitoring modalities in heart failure (HF) have been proposed as being essential for future organization and transition of HF care, however, efficacy has not been proven. A comprehensive meta-analysis of studies on home telemonitoring systems (hTMS) in HF and the effect on clinical outcomes are provided. METHODS AND RESULTS: A systematic literature search was performed in four bibliographic databases, including randomized trials and observational studies that were published during January 1996-July 2022. A random-effects meta-analysis was carried out comparing hTMS with standard of care. All-cause mortality, first HF hospitalization, and total HF hospitalizations were evaluated as study endpoints. Sixty-five non-invasive hTMS studies and 27 invasive hTMS studies enrolled 36 549 HF patients, with a mean follow-up of 11.5 months. In patients using hTMS compared with standard of care, a significant 16% reduction in all-cause mortality was observed [pooled odds ratio (OR): 0.84, 95% confidence interval (CI): 0.77-0.93, I2: 24%], as well as a significant 19% reduction in first HF hospitalization (OR: 0.81, 95% CI 0.74-0.88, I2: 22%) and a 15% reduction in total HF hospitalizations (pooled incidence rate ratio: 0.85, 95% CI 0.76-0.96, I2: 70%). CONCLUSION: These results are an advocacy for the use of hTMS in HF patients to reduce all-cause mortality and HF-related hospitalizations. Still, the methods of hTMS remain diverse, so future research should strive to standardize modes of effective hTMS.

OBJECTIVES: We sought to evaluate the impact of mixed aortic stenosis (MAS) on postprocedural aortic regurgitation (PPAR) and clinical outcomes after transcatheter aortic valve implantation (TAVI). BACKGROUND: The impact of MAS of TAVI outcomes is unknown. METHODS AND RESULTS: Data from a multicenter registry were retrospectively analysed. Outcomes were compared between patients with pure aortic stenosis (PAS; associated AR<1+/3+) and MAS (associated AR≥1+/3+). Study objectives were PPAR incidence and short- and long-term mortality. Overall, 1,062 patients were included: 419 (39.4%) with MAS and 643 (60.5%) with PAS. At 30 days, there were no differences in mortality, however, a higher incidence of major bleeding (22.7% vs. 16.8%; P=0.016), PPAR≥1+/3+ (42.6% vs. 26.5%; P<0.001) and lower device success (89.3% vs. 93.3%; P=0.019) was observed in patients with MAS. Of note, MAS was an independent predictor of PPAR≥1+/3+ at multivariable analysis (OR: 2.882; CI: 1.851-4.488; P<0.001). At 2 years of follow-up, no survival differences were present between MAS and PAS groups. Similarly, following stratification for PPAR≥1+/3+, MAS had no protective effect on survival as compared with PAS. CONCLUSIONS: MAS was associated with lower device success and higher PPAR incidence. However, despite these findings, it had no influence on long-term postoperative outcomes.

OBJECTIVES: The aim of the study was to investigate trends over time in the occurrence of left bundle branch block (LBBB) and permanent pacemaker implantation (PPI) after transcatheter aortic valve implantation (TAVI) with the Medtronic CoreValve System (MCS) and Edwards SAPIEN Valve (ESV). BACKGROUND: TAVI-induced conduction abnormalities (TAVI-CAs) such as LBBB and the need for PPI are frequent postoperative complication. New techniques, procedural refinements, and increased awareness are focused on the reduction of these abnormalities. METHODS: Electrocardiograms of 549 patients without preprocedural LBBB and/or pacemaker were assessed to determine the frequency and nature of TAVI-CAs. To study the effect of experience, patients were subdivided per center into tertiles based on the number of procedures. Univariate and multivariate logistic regression was used to study predictors of TAVI-induced LBBB (TAVI-LBBB) and PPI. RESULTS: TAVI-LBBB occurred in 185 patients (33.7%) and significantly decreased over time, from 42.6% to 27.3% (P=0.006). This effect was only significant after implantation of the MCS (59.6% vs. 46.5% vs. 31.1%, P=0.001, ESV: 22.6% vs. 13.1% vs. 24.8%, P=0.11). Between tertiles there was no difference in the frequency of PPI after TAVI (n=73, 13.1% vs. 14.8% vs. 12%, P=0.74). Multivariate analysis revealed that, independent from valve type, depth of implantation was the only significant predictor of TAVI-LBBB (OR [95% C.I.]: 1.16 [1.10-1.24], P<0.001). In case of PPI pre-existing RBBB (OR [95% C.I.]: 7.22 [3.28-15.88], P<0.001) was the only significant predictor. CONCLUSIONS: Over time the frequency of LBBB after TAVI decreased significantly, especially in patients undergoing TAVI with the MCS. Experience and the subsequent reduction in depth of implantation seem responsible for this reduction. Contrary to TAVI-LBBB, the incidence of PPI remained unchanged over time and was not affected by experience. Although experience has led to a decrease in new CAs after TAVI, elucidation of pathophysiologic mechanisms underlying these CAs and subsequent changes in patient stratification, valve design and the procedure are needed to further reduce this complication.

Transcatheter aortic valve implantation (TAVI) has become an established treatment option for patients with aortic stenosis at prohibitive risk to undergo surgical aortic valve replacement. Despite conveying obvious clinical benefits and a decreasing frequency of complications, the occurrence of new conduction abnormalities and arrhythmias remains an important issue. Generally considered a minor complication, they may have a profound impact on prognosis and quality of life after TAVI. Therefore the purpose of this review is to assess and discuss the available information on clinical implications of both new conduction abnormalities and arrhythmias after TAVI.

Aims: Early detection of congestion has demonstrated to improve outcomes in heart failure (HF) patients. However, there is limited access to invasively haemodynamic parameters to guide treatment. This study aims to develop a model to estimate the invasively measured pulmonary capillary wedge pressure (PCWP) using non-invasive measurements with both traditional statistics and machine learning (ML) techniques. Methods and results: The study involved patients undergoing right-sided heart catheterization at Erasmus MC, Rotterdam, from 2017 to 2022. Invasively measured PCWP served as outcomes. Model features included non-invasive measurements of arterial blood pressure, saturation, heart rate (variability), weight, and temperature. Various traditional and ML techniques were used, and performance was assessed using R2 and area under the curve (AUC) for regression and classification models, respectively. A total of 853 procedures were included, of which 31% had HF as primary diagnosis and 49% had a PCWP of 12â mmHg or higher. The mean age of the cohort was 59 ± 14 years, and 52% were male. The heart rate variability had the highest correlation with the PCWP with a correlation of 0.16. All the regression models resulted in low R2 values of up to 0.04, and the classification models resulted in AUC values of up to 0.59. Conclusion: In this study, non-invasive methods, both traditional and ML-based, showed limited correlation to PCWP. This highlights the weak correlation between traditional HF monitoring and haemodynamic parameters, also emphasizing the limitations of single non-invasive measurements. Future research should explore trend analysis and additional features to improve non-invasive haemodynamic monitoring, as there is a clear demand for further advancements in this field.
RESUMO
AIMS: Heart failure (HF) is a chronic and progressive syndrome associated with a poor prognosis. While it may seem intuitive that the risk of adverse outcomes varies across the different stages of HF, an overview of these risks is lacking. This study aims to determine the risk of all-cause mortality and HF hospitalizations associated with new-onset HF, chronic HF (CHF), worsening HF (WHF), and advanced HF. METHODS AND RESULTS: We performed a systematic review of observational studies from 2012 to 2022 using five different databases. The primary outcomes were 30-day and 1-year all-cause mortality, as well as 1-year HF hospitalization. Studies were pooled using random effects meta-analysis, and mixed-effects meta-regression was used to compare the different HF groups. Among the 15 759 studies screened, 66 were included representing 862 046 HF patients. Pooled 30-day mortality rates did not reveal a significant distinction between hospital-admitted patients, with rates of 10.13% for new-onset HF and 8.11% for WHF (p = 0.10). However, the 1-year mortality risk differed and increased stepwise from CHF to advanced HF, with a rate of 8.47% (95% confidence interval [CI] 7.24-9.89) for CHF, 21.15% (95% CI 17.78-24.95) for new-onset HF, 26.84% (95% CI 23.74-30.19) for WHF, and 29.74% (95% CI 24.15-36.10) for advanced HF. Readmission rates for HF at 1 year followed a similar trend. CONCLUSIONS: Our meta-analysis of observational studies confirms the different risk for adverse outcomes across the distinct HF stages. Moreover, it emphasizes the negative prognostic value of WHF as the first progressive stage from CHF towards advanced HF.

Aims: Invasive haemodynamic monitoring of heart failure (HF) is used to detect deterioration in an early phase thereby preventing hospitalizations. However, this invasive approach is costly and presently lacks widespread accessibility. Hence, there is a pressing need to identify an alternative non-invasive method that is reliable and more readily available. In this pilot study, we investigated the relation between wrist-derived photoplethysmography (PPG) signals and the invasively measured pulmonary capillary wedge pressure (PCWP). Methods and results: Fourteen patients with aortic valve stenosis who underwent transcatheter aortic valve replacement with concomitant right heart catheterization and PPG measurements were included. Six unique features of the PPG signals [heart rate, heart rate variability, systolic amplitude (SA), diastolic amplitude, crest time (CT), and large artery stiffness index (LASI)] were extracted. These features were used to estimate the continuous PCWP values and the categorized PCWP (low < 12â mmHg vs. high ≥ 12â mmHg). All PPG features resulted in regression models that showed low correlations with the invasively measured PCWP. Classification models resulted in higher performances: the model based on the SA and the model based on the LASI both resulted in an area under the curve (AUC) of 0.86 and the model based on the CT resulted in an AUC of 0.72. Conclusion: These results demonstrate the capability to non-invasively classify patients into clinically meaningful categories of PCWP using PPG signals from a wrist-worn wearable device. To enhance and fully explore its potential, the relationship between PPG and PCWP should be further investigated in a larger cohort of HF patients.
RESUMO
Social media (SoMe) has witnessed remarkable growth and emerged as a dominant method of communication worldwide. Platforms such as Facebook, X (formerly Twitter), LinkedIn, Instagram, TikTok, and YouTube have become important tools of the digital native generation. In the field of medicine, particularly, cardiology, attitudes towards SoMe have shifted, and professionals increasingly utilize it to share scientific findings, network with experts, and enhance teaching and learning. Notably, SoMe is being leveraged for teaching purposes, including the sharing of challenging and intriguing cases. However, sharing patient data, including photos or images, online carries significant implications and risks, potentially compromising individual privacy both online and offline. Privacy and data protection are fundamental rights within European Union treaties, and the General Data Protection Regulation (GDPR) serves as the cornerstone of data protection legislation. The GDPR outlines crucial requirements, such as obtaining 'consent' and implementing 'anonymization', that must be met before sharing sensitive and patient-identifiable information. Additionally, it is vital to consider the patient's perspective and prioritize ethical and social considerations when addressing challenges associated with sharing patient information on SoMe platforms. Given the absence of a peer-review process and clear guidelines, we present an initial approach, a code of conduct, and recommendations for the ethical use of SoMe. In conclusion, this comprehensive review underscores the importance of a balanced approach that ensures patient privacy and upholds ethical standards while harnessing the immense potential of SoMe to advance cardiology practice and facilitate knowledge dissemination.
RESUMO
AIMS: Despite clear guideline recommendations for initiating four drug classes in all patients with heart failure (HF) with reduced ejection fraction (HFrEF) and the availability of rapid titration schemes, information on real-world implementation lags behind. Closely following the 2021 ESC HF guidelines and 2023 focused update, the TITRATE-HF study started to prospectively investigate the use, sequencing, and titration of guideline-directed medical therapy (GDMT) in HF patients, including the identification of implementation barriers. METHODS AND RESULTS: TITRATE-HF is an ongoing long-term HF registry conducted in the Netherlands. Overall, 4288 patients from 48 hospitals were included. Among these patients, 1732 presented with de novo, 2240 with chronic, and 316 with worsening HF. The median age was 71 years (interquartile range [IQR] 63-78), 29% were female, and median ejection fraction was 35% (IQR 25-40). In total, 44% of chronic and worsening HFrEF patients were prescribed quadruple therapy. However, only 1% of HFrEF patients achieved target dose for all drug classes. In addition, quadruple therapy was more often prescribed to patients treated in a dedicated HF outpatient clinic as compared to a general cardiology outpatient clinic. In each GDMT drug class, 19% to 36% of non-use in HFrEF patients was related to side-effects, intolerances, or contraindications. In the de novo HF cohort, 49% of patients already used one or more GDMT drug classes for other indications than HF. CONCLUSION: This first analysis of the TITRATE-HF study reports relatively high use of GDMT in a contemporary HF cohort, while still showing room for improvement regarding quadruple therapy. Importantly, the use and dose of GDMT were suboptimal, with the reasons often remaining unclear. This underscores the urgency for further optimization of GDMT and implementation strategies within HF management.

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is a novel therapy for treatment of severe aortic stenosis. Although 30% to 50% of patients develop new left bundle-branch block (LBBB), its effect on clinical outcome is unclear. METHODS AND RESULTS: Data were collected in a multicenter registry encompassing TAVI patients from 2005 until 2010. The all-cause mortality rate at follow-up was compared between patients who did and did not develop new LBBB. Of 679 patients analyzed, 387 (57.0%) underwent TAVI with the Medtronic CoreValve System and 292 (43.0%) with the Edwards SAPIEN valve. A total of 233 patients (34.3%) developed new LBBB. Median follow-up was 449.5 (interquartile range, 174-834) days in patients with and 450 (interquartile range, 253-725) days in patients without LBBB (P=0.90). All-cause mortality was 37.8% (n=88) in patients with LBBB and 24.0% (n=107) in patients without LBBB (P=0.002). By multivariate regression analysis, independent predictors of all-cause mortality were TAVI-induced LBBB (hazard ratio [HR], 1.54; confidence interval [CI], 1.12-2.10), chronic obstructive lung disease (HR, 1.56; CI, 1.15-2.10), female sex (HR, 1.39; CI, 1.04-1.85), left ventricular ejection fraction ≤50% (HR, 1.38; CI, 1.02-1.86), and baseline creatinine (HR, 1.32; CI, 1.19-1.43). LBBB was more frequent after implantation of the Medtronic CoreValve System than after Edwards SAPIEN implantation (51.1% and 12.0%, respectively; P<0.001), but device type did not influence the mortality risk of TAVI-induced LBBB. CONCLUSIONS: All-cause mortality after TAVI is higher in patients who develop LBBB than in patients who do not. TAVI-induced LBBB is an independent predictor of mortality.

BACKGROUND: Transfemoral transcatheter aortic valve implantation (TF-TAVI) is a viable and safe treatment strategy for patients with symptomatic severe aortic stenosis and high operative risk and has been introduced as such in the recently updated European guidelines on the management of valvular heart disease.Our aim was to assess trends in outcome after TF-TAVI. METHODS: Propensity score-matched analysis of a multicenter registry of consecutive patients undergoing TF-TAVI subdivided into 3 tertiles based on enrollment date was performed. Three tertiles of 214 propensity score-matched patients were compared. RESULTS: With mounting experience and moving from the initial to the last cohort, procedural contrast volume and radiation time decreased. Over time, there were less major vascular complications (15% vs 7.9%, P = .023), life-threatening bleedings (17.8% vs 7.9%, P = .003), and major bleedings (22.4% vs 12.1%, P = .007). Major vascular complications and life-threatening bleedings caused by closure device failure decreased significantly (9.2% vs 3.1% [P = .01] and 5.7% vs 1 % [P = .01], respectively). The combined safety end point dropped from 31.3% in tertile (T) (T1) to 17.8% in T3 (P < .001). By multivariable analysis, the last cohort as compared with the initial cohort was associated with significant reductions in 30-day mortality (odds ratio [OR] 0.35, 95% CI 0.12-0.96), stage 3 AKI (OR 0.12, 95% CI 0.29-0.93), and the combined safety end point (OR 0.52, 95% CI 0.29-0.93). One-year survival improved significantly (T1 79% vs T3 86%, P = .016). CONCLUSIONS: Over time, TAVI is performed with significant reductions in major vascular complications, life-threatening bleedings, and the combined clinical safety end point and improved 1-year survival.

BACKGROUND: Only limited and conflicting data on the impact of preoperative chronic kidney disease (CKD) on outcomes after transcatheter aortic valve implantation (TAVI) are available. METHODS: We retrospectively analyzed pooled data from the prospective TAVI databases of 4 centers (942 patients). Valve Academic Research Consortium end point definitions were used. The outcomes were compared among patients with normal estimated glomerular filtration rate (≥90 mL/min), mild (60-89 mL/min), moderate (30-59 mL/min), and severe (<30 mL/min) CKD and those on chronic hemodialysis (HD). The primary end point was 1-year survival. RESULTS: A total of 109 patients had a normal estimated glomerular filtration rate (11.6%); 329 (34.9%) had mild, 399 (42.5%) moderate, 72 (7.5%) severe CKD, and 33 (3.5%) were on HD. Baseline and procedural characteristics were similar among all groups except for Logistic EuroSCORE. Major stroke, life-threatening bleeding, all-cause 30-day mortality (HD 15.2%, severe CKD 8.3%, moderate CKD 8.3%, mild CKD 6.7%, normal 1.8%, P = .007) and 1-year survival (HD 54.8%, severe CKD 67.2%, moderate CKD 80.0%, mild CKD 85.2%, normal eGFR 91.4%, HD vs severe CKD P = .23, severe CKD vs moderate CKD P = .002, moderate CKD vs mild CKD P = .04, moderate CKD vs normal eGFR P = .03, by log-rank test) differed significantly across groups. Through multivariable analysis, HD and severe CKD were independently associated with an increased risk of 1-year mortality (hazard ratios 5.07 [95% CI 1.79-14.35, P = .002] and 4.03 [95% CI 1.52-10.69, P = .005], respectively). CONCLUSIONS: Patients with CKD who undergo TAVI have a higher-risk profile and worse 30-day and 1-year outcomes. Chronic hemodialysis and severe preprocedural CKD are independently associated with an increased risk of 1-year mortality after TAVI.

AIMS: Heart failure (HF) is a progressive disease in which periods of clinical stability are interrupted by episodes of clinical deterioration known as worsening heart failure (WHF). Patients who develop WHF are at high risk of subsequent death, rehospitalization, and excessive healthcare costs. As such, WHF could be seen as a separate disease stage and precursor of advanced HF. Whether WHF has a substantial health, societal, and economic impact evidence regarding its multifactorial nature and the specific barriers in treatment, including advanced HF therapies, remains scarce. The CHAIN-HF registry aims to describe the incidence, characteristics, current treatment, and outcomes of WHF. Additionally, it will promote structured regional collaboration and educate on increasing awareness for WHF and describe the implementation of guideline directed medical therapy and utilization of advanced HF therapies in a collaborative network. METHODS AND RESULTS: The CHAIN-HF registry is a prospective, observational, and multicentre study from the collaborating hospitals (Rijnmond HF Network) in the Rotterdam area. Unselected and consecutive patients (irrespective of ejection fraction) with a WHF event will be included. Comprehensive data including demographics, co-morbidities, treatment, and in-hospital and post-discharge outcomes will be collected. Notably, data on socio-economic status, treatment decisions, and referral for advanced HF therapies will be included. CONCLUSIONS: CHAIN-HF will be the first prospective, dedicated WHF registry in a collaborative network of hospitals that will provide robust real-world evidence on the incidence, characteristics, and outcomes of WHF. Moreover, it will provide information on of the value of regional collaboration to improve awareness and outcomes of WHF.

BACKGROUND: Little is known about the impact of bleeding and red blood cells transfusion (RBC) on the outcome post transcatheter aortic valve implantation (TAVI). METHODS: Between November 2005 and August 2011, 943 consecutive patients underwent TAVI. Bleeding was assessed according to the Valve Academic Research Consortium definitions. Patients receiving RBC were compared to those not requiring transfusion. RESULTS: Life-threatening and major bleedings occurred respectively in 13.9% and 20.9% of the patients, significantly more frequently in the RBC cohort. Vascular complications occurred in 23.2% of the patients. Major and minor vascular complications were more frequent in the RBC group: 19.3 vs 5.2%, P < .001; 15.3 vs 9%, P = .003, respectively. Thirty-day all-cause mortality was 7.2%. Of the overall cohort, 38.9% required RBC transfusion; those receiving at least 4 U of RBC had higher 30-day all-cause mortality than those receiving 1 to 4 U of RBC and those not requiring transfusion: 14.4%, vs 6.3% vs 6.3%, respectively, P = .008. By multivariate analysis, transfusion of RBC was associated with an increased 30-day and 1-year mortality. Major stroke and all stages of acute kidney injury were significantly more frequent in the RBC cohort. CONCLUSIONS: Bleeding is frequent after TAVI, mainly driven by vascular complications. RBC transfusion was associated with increased mortality at 1 year and increased risk of major stroke and acute kidney injury. Specific scores are needed to identify the patients at higher risk for TAVI-related bleeding and RBC transfusion.

OBJECTIVES: To determine the incidence, timing and predictors of periprocedural valve dislodgment with the Medtronic Corevalve System (MCS). BACKGROUND: Periprocedural valve dislodgment may occur during transcatheter aortic valve implantation (TAVI). METHODS: Ninety-eight consecutive patients underwent TAVI with the MCS after a comprehensive baseline assessment including invasive angiography, echocardiography, and Multi-Slice Computed Tomography (MSCT). The invasive monitoring charts and angiographic studies of all TAVI procedures were reviewed to determine the incidence and timing of valve dislodgment. RESULTS: Valve dislodgment occurred in 18 patients. Patients with valve dislodgment had a larger Aortic Valve Area (0.76 ± 0.25 cm(2) vs. 0.61 ± 0.19 cm(2) , P = 0.007), lower mean transaortic gradient (37.65 ± 14.62 mm Hg vs. 47.11 ± 16.08 mm Hg, P = 0.03) and significantly less aortic root calcification (Agatston score median 1951 AU (IQR, 799-3103) vs. 3289 AU (IQR 2097-4481), P = 0.016). A lower aortic root calcium score (Agatston score < 2359 AU) was the single independent predictor for valve dislodgment (OR 3.10, 1.09-8.84). After valve dislodgment, the valve could be successfully retrieved and implanted in the proper anatomic location in all cases. Valve dislodgment was associated with a lower incidence of post-procedural AR ≥ 2 (11.1% vs. 34.6%, P = 0.05). There were no relevant procedural or clinical implications to valve dislodgment. CONCLUSIONS: The incidence of periprocedural valve dislodgment was 18% in these series. Less aortic root calcification appeared the single independent predictor.

BACKGROUND: Endomyocardial biopsy (EMB) has an important role in determining the pathogenesis of new-onset acute heart failure (new-AHF) when noninvasive testing is impossible. However, data on safety and histopathologic outcomes in patients requiring veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is lacking. METHODS: A retrospective, multicenter cohort of patients undergoing EMB while requiring VA-ECMO for new-AHF between 1990 and 2020 was compared with a cohort of nontransplant related biopsies not requiring VA-ECMO. Primary end point of the study was to determine the safety of EMB. Additionally, we describe the underlying pathogenesis causing new-AHF based on histopathologic examination of the samples obtained. RESULTS: A total of 23 patients underwent EMB while requiring VA-ECMO (10.0%), 125 (54.3%) during an unplanned admission, and 82 (35.7%) in elective setting. Major complications occurred in 8.3% of all procedures with a significantly higher rate in patients requiring VA-ECMO (26.1% versus 8.0% versus 3.7%, P=0.003) predominately due to the occurrence of sustained ventricular tachycardia or need of resuscitation (13.0% versus 3.2% versus 1.2%, P=0.02). EMB led to a histopathologic diagnosis in 78.3% of the patients requiring VA-ECMO which consisted primarily of patients with myocarditis (73.9%). CONCLUSIONS: EMB in patients requiring VA-ECMO can be performed albeit with a substantial risk of major complications. The risk of the procedure was offset by a histopathologic diagnosis in 78.3% of the patients, which for the majority consisted of patients with myocarditis. The important therapeutic and prognostic implications of establishing an underlying pathogenesis causing new-AHF in this population warrant further refinement to improve procedural safety.

AIMS: We sought to evaluate the impact of permanent pacemaker (PPM) implantation on two-year mortality and one-year left ventricular ejection fraction recovery (∆LVEFR=one-year LVEF-baseline LVEF) after transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS: We pooled patient-level data from four European institutions with significant TAVI volume. Outcomes were compared between patients without PPM (no-PPM), patients with PPM prior to TAVI (old-PPM) and patients with PPM implanted after TAVI (new-PPM). Out of 1,062 patients included in the pooled data set, 783 (73.7%) were in the no-PPM group, 164 (15.4%) in the new-PPM group and 115 (10.8%) in the old-PPM group. All-cause and cardiovascular mortality at two years were similar for patients with no-PPM and new-PPM (adjusted HR 1.11, 95% CI: 0.74-1.67; p=0.62; and adjusted HR 1.16, 95% CI: 0.68-1.98; p=0.59). Conversely, old-PPM was associated with increased risk of both all-cause and cardiovascular mortality vs. no-PPM. By multivariable analysis new-PPM did not affect LVEFR, while old-PPM did. We observed a multiplicative interaction, between new-PPM and post-procedural aortic regurgitation ≥1+ on two-year mortality and one-year LVEFR, with increased risk of death and impaired LVEFR in patients with new-PPM and post-procedural aortic regurgitation (PPAR) ≥1+ (both pinteraction<0.0001). CONCLUSIONS: In patients undergoing TAVI, the presence of a PPM at baseline yielded a negative effect on long-term prognosis while new-PPM did not. The combination of new-PPM with PPAR adversely impacts on survival and LV function recovery.
