Real-World Management Strategies of Anticoagulated Atrial Fibrillation Patients After a Clinically Significant Bleeding Episode.

BACKGROUND: Systemic anticoagulation for stroke prevention in patients with atrial fibrillation (AF) carries inherent bleeding risks, and determining whether and when to resume anticoagulation after significant bleeding is a common dilemma. We aimed to describe the clinical characteristics of AF patients discharged after a bleeding event, document real-life thromboembolic prevention strategy (TPS), and analyse their associated clinical outcomes. METHODS: We retrospectively reviewed the charts of anticoagulated AF patients admitted for bleeding from 2017 to 2019. RESULTS: A total of 140 patients were included, with a mean age of 78.6 years. Four discharge groups were defined: 75 patients (53.5%) had optimal anticoagulation (OA), 37 (26.4%) had a suboptimal antithrombotic regimen (SAR; low-dose direct oral anticoagulants without dose-reduction criteria or antiplatelet therapy), 10 (7.1%) were referred for left atrial appendage occlusion (LAAO), and 18 (12.9%) left without any TPS. All-cause mortality at 2 years was high (28.6%) but not statistically different between groups (P = 0.71). Patients discharged with a TPS (OA/SAR/LAAO referral) were more likely to be readmitted for bleeding at 2 years (34% vs 0%; P = 0.002), and those discharged without a TPS had higher rates of stroke (16.6% vs 1.4%; P = 0.003). SAR yielded readmission rates for bleeding similar to resumption of OA (27% vs 34.7%; P = 0.41) but was associated with high rates of death or readmission at 2 years. CONCLUSIONS: This real-life cohort reveals that clinicians frequently downgrade or discontinue long-term thromboembolic protection after a bleeding event despite current guideline recommendations to the contrary, and downgrading resulted in bleeding risk similar to OA.

Correlation between measured and predicted mismatch with valve hemodynamics in transcatheter aortic valve replacement: A sex-based analysis.

BACKGROUND: Data regarding the reliability of predicted effective orifice area indexed (pEOAi) is scarce in transcatheter aortic valve replacement (TAVR). AIMS: To assess the validity of the pEOAi in TAVR by correlating its value with echocardiography-derived hemodynamic data. METHODS: A single-center retrospective cohort study of TAVR patients from 2012 to 2021 with available echocardiograms was conducted. Patient-prosthesis mismatch (PPM) was defined based on the Valve Academic Research Consortium 3 criteria. The main endpoints were the congruence of measured effective orifice area indexed (EOAi) and pEOAi with the hemodynamic data obtained by echocardiography. The secondary endpoint included a correlation of predicted PPM (pPPM) and measured PPM (mPPM) with postoperative New York Heart Association (NYHA) status. RESULTS: A total of 318 patients were included. pPPM was more frequent than mPPM (54 [17%]; all moderate PPM vs. 39 [12.3%]: 32 moderate and 7 severe PPM). Predicted and measured EOAi were statistically correlated with postprocedural transvalvular mean gradient and Doppler velocity index (all p < 0.001), including in both sex-based subgroups. The positive predictive value and negative predictive value (NPV) of pPPM for postprocedural transvalvular mean gradient ≥ 20 mmHg were 16% and 97%, respectively. Only pPPM was significantly more prevalent in the group in which NYHA failed to improve than in those with symptom improvement (30.1% vs. 16%, p = 0.027). CONCLUSION: Predicted PPM has an excellent NPV for postprocedural transvalvular mean gradient ≥ 20 mmHg and seems to be a good predictor of NYHA status evolution as opposed to measured PPM. Predicted EOAi can be used in procedural planning to reduce the risk of PPM in both TAVR male and female patients.

The Use of Three-Dimensional Printing in Cardiac Structural Disease: A Review.

OBJECTIVE: Three-dimensional printing (3DP), or additive fabrication, is a process in which a physical 3D model is created using a multitude of 2-dimensional images. This process has been applied to numerous surgical subspecialties with growing interest for the use of 3DP in adult structural heart disease. This scoping review evaluates the use of 3DP in transcatheter and surgical aortic and mitral valve interventions as well as left atrial appendage occlusion in terms of its practical and clinical application. METHODS: Articles were identified through PubMed and Embase using MeSH search terms as well as independent searches. A total of 645 articles were screened, and 37 were retained for qualitative analysis. RESULTS: Operative planning was coded in 100% of articles, complication prevention in 43%, medical education in 5.4%, patient education in 0%, and simulation in 5.4%. CONCLUSIONS: The main uses of 3DP in acquired structural heart disease are centered around operative planning and complication prevention, with moderate use regarding surgical simulation and infrequent use regarding medical and/or patient education. Although patient anatomy varies greatly, deploying 3DP as a large-scale tool remains a possibility. The more 3D models are made, the more can be learned about demographic subsets of patient populations. Due to the lack of standard operating procedures for the creation of 3DP models, the cost-effectiveness of these models is hard to determine and likely center specific. More research into this facet could inform centers that wish to implement this tool.

Closing the door in front of a torrential mitral regurgitation.

BACKGROUND: Treatment of symptomatic severe mitral regurgitation (MR) is challenging in patients who are not candidates for surgical intervention. CASE DESCRIPTION: We report the case of a 64-year-old female with multiple comorbidities who was found to have severe MR due to a large mitral valve non coaptation. CONCLUSIONS: In this case report, we show the potential of transcatheter edge-to-edge mitral valve repair using MitraClip for the treatment of torrential MR due to a large mitral valve non-coaptation in a patient with no prior history of coronary artery disease and in whom surgical intervention was not an option.

Mitral Valve Infective Endocarditis after Trans-Catheter Aortic Valve Implantation.

Scarce data exist on mitral valve (MV) infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI). This multicenter study included a total of 579 patients with a diagnosis of definite IE after TAVI from the IE after TAVI International Registry and aimed to evaluate the incidence, characteristics, management, and outcomes of MV-IE after TAVI. A total of 86 patients (14.9%) had MV-IE. These patients were compared with 284 patients (49.1%) with involvement of the transcatheter heart valve (THV) only. Two factors were found to be associated with MV-IE: the use of self-expanding valves (adjusted odds ratio 2.49, 95% confidence interval [CI] 1.23 to 5.07, p = 0.012), and the presence of an aortic regurgitation ≥2 at discharge (adjusted odds ratio 3.33; 95% CI 1.43 to 7.73, p <0.01). There were no differences in IE timing and causative microorganisms between groups, but surgical management was significantly lower in patients with MV-IE (6.0%, vs 21.6% in patients with THV-IE, p = 0.001). All-cause mortality rates at 2-year follow-up were high and similar between patients with MV-IE (51.4%, 95% CI 39.8 to 64.1) and patients with THV-IE (51.5%, 95% CI 45.4 to 58.0) (log-rank p = 0.295). The factors independently associated with increased mortality risk in patients with MV-IE were the occurrence of heart failure (adjusted p <0.001) and septic shock (adjusted p <0.01) during the index hospitalization. One of 6 IE episodes after TAVI is localized on the MV. The implantation of a self-expanding THV and the presence of an aortic regurgitation ≥2 at discharge were associated with MV-IE. Patients with MV-IE were rarely operated on and had a poor prognosis at 2-year follow-up.

Surgical Treatment of Patients With Infective Endocarditis After Transcatheter Aortic Valve Implantation.

BACKGROUND: The optimal treatment of patients developing infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI) is uncertain. OBJECTIVES: The goal of this study was to investigate the clinical characteristics and outcomes of patients with TAVI-IE treated with cardiac surgery and antibiotics (IE-CS) compared with patients treated with antibiotics alone (IE-AB). METHODS: Crude and inverse probability of treatment weighting analyses were applied for the treatment effect of cardiac surgery vs medical therapy on 1-year all-cause mortality in patients with definite TAVI-IE. The study used data from the Infectious Endocarditis after TAVI International Registry. RESULTS: Among 584 patients, 111 patients (19%) were treated with IE-CS and 473 patients (81%) with IE-AB. Compared with IE-AB, IE-CS was not associated with a lower in-hospital mortality (HRunadj: 0.85; 95% CI: 0.58-1.25) and 1-year all-cause mortality (HRunadj: 0.88; 95% CI: 0.64-1.22) in the crude cohort. After adjusting for selection and immortal time bias, IE-CS compared with IE-AB was also not associated with lower mortality rates for in-hospital mortality (HRadj: 0.92; 95% CI: 0.80-1.05) and 1-year all-cause mortality (HRadj: 0.95; 95% CI: 0.84-1.07). Results remained similar when patients with and without TAVI prosthesis involvement were analyzed separately. Predictors for in-hospital and 1-year all-cause mortality included logistic EuroSCORE I, Staphylococcus aureus, acute renal failure, persistent bacteremia, and septic shock. CONCLUSIONS: In this registry, the majority of patients with TAVI-IE were treated with antibiotics alone. Cardiac surgery was not associated with an improved all-cause in-hospital or 1-year mortality. The high mortality of patients with TAVI-IE was strongly linked to patients' characteristics, pathogen, and IE-related complications.

Infective Endocarditis Caused by Staphylococcus aureus After Transcatheter Aortic Valve Replacement.

BACKGROUND: Staphylococcus aureus (SA) has been extensively studied as causative microorganism of surgical prosthetic-valve infective endocarditis (IE). However, scarce evidence exists on SA IE after transcatheter aortic valve replacement (TAVR). METHODS: Data were obtained from the Infectious Endocarditis After TAVR International Registry, including patients with definite IE after TAVR from 59 centres in 11 countries. Patients were divided into 2 groups according to microbiologic etiology: non-SA IE vs SA IE. RESULTS: SA IE was identified in 141 patients out of 573 (24.6%), methicillin-sensitive SA in most cases (115/141, 81.6%). Self-expanding valves were more common than balloon-expandable valves in patients presenting with early SA IE. Major bleeding and sepsis complicating TAVR, neurologic symptoms or systemic embolism at admission, and IE with cardiac device involvement (other than the TAVR prosthesis) were associated with SA IE (P < 0.05 for all). Among patients with IE after TAVR, the likelihood of SA IE increased from 19% in the absence of those risk factors to 84.6% if ≥ 3 risk factors were present. In-hospital (47.8% vs 26.9%; P < 0.001) and 2-year (71.5% vs 49.6%; P < 0.001) mortality rates were higher among patients with SA IE vs non-SA IE. Surgery at the time of index SA IE episode was associated with lower mortality at follow-up compared with medical therapy alone (adjusted hazard ratio 0.46, 95% CI 0.22-0.96; P = 0.038). CONCLUSIONS: SA IE represented approximately 25% of IE cases after TAVR and was associated with very high in-hospital and late mortality. The presence of some features determined a higher likelihood of SA IE and could help to orientate early antibiotic regimen selection. Surgery at index SA IE was associated with improved outcomes, and its role should be evaluated in future studies.

Does "Obesity Paradox" Apply for Patients Undergoing Transcatheter Aortic Valve Replacement?

BACKGROUND: Data is controversial regarding the existence of an "obesity paradox" in patients undergoing Transcatheter Aortic Valve Replacement (TAVR). We sought to investigate the prognostic value of the body mass index (BMI) on outcomes following TAVR. METHODS: This is an observational, single-center study involving all patients who underwent TAVR from 2009 to 2019. BMI was calculated in all patients before TAVR. The cohort was subdivided into four groups: underweight (<20 kg/m2), normal weight (≥20 to <25 kg/m2), overweight (≥25 to <30 kg/m2) and obese (≥30 kg/m2). The main endpoint was all-cause 30-day and one-year mortality. RESULTS: A total of 412 patients (mean age 79.6 ± 7.8 years, mean STS score 5.3 ± 3.6) were included. Patients were grouped as follows: underweight (n = 35, 8.5%), normal weight (n = 121, 29.4%), overweight (n = 140, 34%) and obese (n = 116, 28.1%). Obese patients were younger, included more females and had lower STS score than the rest of the cohort whereas underweight patients were older, had higher STS score, more chronic kidney disease, more left ventricular dysfunction and more often underwent non-transfemoral TAVR. BMI predicted 30-day survival (AUC:0.692 [95%CI 0.522-0.862]; p = 0.030) with an optimal cut-off of 24.4 (sensitivity = 66.6%, specificity = 63.6%). On multivariate analysis, higher BMI trended toward lower 30-day mortality (HR = 0.87 [95%CI 0.75-1.01]; p = 0.071). Thirty-day mortality was higher in the underweight group (8.3%) in comparison with other BMI subgroups (normal weight 2.5%, overweight 1.4%, obese 0.9%; p = 0.045). However, no significant difference was found after adjustment of confounders (all p = NS). BMI did not predict one-year mortality. No significant difference in one-year survival was observed between the four BMI subgroups (log rank p = 0.925). CONCLUSION: BMI could represent an interesting prognostic tool for short-term mortality in patients undergoing TAVR. BMI < 20 kg/m2 was associated with higher 30-day mortality. Symptoms improved similarly in obese patients compared to lower BMI patients. For 30-day survivors, no evidence of the existence of an obesity paradox was observed in this cohort.

Assessing the Accuracy of a Second-Generation Optical Sensor Pressure Wire in a Wire-to-Wire Comparison (The ACCURACY Study).

BACKGROUND: The phenomenon of "pressure drift" increases uncertainty about the correct FFR value. Redesigned and incorporating an optical pressure sensor, the "OptoWire Deux™" is purported to be less prone to the pressure drift seen with piezoelectric coronary pressure wires. The aim of this first in vivo real-world clinical study is to evaluate the performance of OptoWire Deux™ in terms of measurements agreement and propensity to pressure drift in a wire to wire comparison. METHODS: This is a single center, prospective, non-blinded clinical investigation enrolling 45 consecutive patients with a clinical indication for coronary lesion FFR assessment. Lesions were either simultaneously assessed with two optical sensor pressure wires (OSPW) (Group O-O; 30 patients, 34 lesions) or one OSPW and one piezoelectric pressure wire (PEPW) simultaneously (Group O-P; 15 patients, 15 lesions). Significant drift was defined as a pressure ratio deviation of >0.03. RESULTS: Mean FFR measurements in Group OO were not statistically different between the two sets of OSPW (overall 0.84±0.10; P = 0.52). In Group OP, however, mean FFR measurement with PEPW (0.85±0.09) was numerically lower than that observed with the OSPW (0.88±0.08; P = 0.09). Level of agreement using the Bland-Altman method was higher when 2 OSPW were used for FFR assessment (-0.002 95% CI [-0.033,0.029] vs. 0.026 95% CI [-0.078, 0.130], respectively). The rate of drift was significantly lower with an OSPW compared to a PEPW (4.8% vs. 26.7% respectively, P = 0.02). CONCLUSION: The optical sensor guidewire showed a high level of readings' agreement after simultaneous usage of 2 optical sensor guidewires. There was also significantly less drift when compared to a piezoelectric guidewire.

Perivalvular Extension of Infective Endocarditis After Transcatheter Aortic Valve Replacement.

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; P = .003) and IE secondary to coagulase-negative staphylococci (ORadj, 2.71; 95% CI: 1.57-4.69; P < .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, P < .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 (padj < 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.

Temporal Trends, Characteristics, and Outcomes of Infective Endocarditis After Transcatheter Aortic Valve Replacement

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; P = .12), but the rate of early IE was lower in the CC (2.29‰ vs 4.89‰, P < .001). Enterococci were the most frequent microorganism. Most patients presented complicated IE (CC: 67.7%; HC: 69.6%; P = .66), but the rate of surgical treatment remained low (CC: 20.7%; HC: 17.3%; P = .32). The CC exhibited lower rates of in-hospital acute kidney injury (35.1% vs 44.6%; P = .036) and in-hospital (26.6% vs 36.4%; P = .016) and 1-year (37.8% vs 53.5%; P < .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 (P < .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.

Challenging Diagnosis of Patent Foramen Ovale in Presence of a Large Eustachian Valve.

We report the case of a 39-year-old woman who presented with cryptogenic stroke. Conventional and contrast echocardiography modalities noticed a large Eustachian valve (EV) but failed to identify any right-to-left shunt. Conversely, contrast-transcranial Doppler revealed a grade 3 right-to-left shunt. Contrast echocardiography was repeated with bubble injections through both an upper extremity and a femoral vein, 10 min apart from each other. While no shunt was observed following upper extremity injection, >20 bubbles crossed the inter-atrial septum when contrast was injected via femoral vein confirming the diagnosis of patent foramen ovale.

Stroke Complicating Infective Endocarditis After Transcatheter Aortic Valve Replacement.

BACKGROUND: Stroke is one of the most common and potentially disabling complications of infective endocarditis (IE). However, scarce data exist about stroke complicating IE after transcatheter aortic valve replacement (TAVR). OBJECTIVES: The purpose of this study was to determine the incidence, risk factors, clinical characteristics, management, and outcomes of patients with definite IE after TAVR complicated by stroke during index IE hospitalization. METHODS: Data from the Infectious Endocarditis after TAVR International Registry (including 569 patients who developed definite IE following TAVR from 59 centers in 11 countries) was analyzed. Patients were divided into two groups according to stroke occurrence during IE admission (stroke [S-IE] vs. no stroke [NS-IE]). RESULTS: A total of 57 (10%) patients had a stroke during IE hospitalization, with no differences in causative microorganism between groups. S-IE patients exhibited higher rates of acute renal failure, systemic embolization, and persistent bacteremia (p < 0.05 for all). Previous stroke before IE, residual aortic regurgitation ≥moderate after TAVR, balloon-expandable valves, IE within 30 days after TAVR, and vegetation size >8 mm were associated with a higher risk of stroke during the index IE hospitalization (p < 0.05 for all). Stroke rate in patients with no risk factors was 3.1% and increased up to 60% in the presence of >3 risk factors. S-IE patients had higher rates of in-hospital mortality (54.4% vs. 28.7%; p < 0.001) and overall mortality at 1 year (66.3% vs. 45.6%; p < 0.001). Surgical treatment was not associated with improved outcomes in S-IE patients (in-hospital mortality: 46.2% in surgical vs. 58.1% in no surgical treatment; p = 0.47). CONCLUSIONS: Stroke occurred in 1 of 10 patients with IE post-TAVR. A history of stroke, short time between TAVR and IE, vegetation size, valve prosthesis type, and residual aortic regurgitation determined an increased risk. The occurrence of stroke was associated with increased in-hospital and 1-year mortality rates, and surgical treatment failed to improve clinical outcomes.

Higher logistic EuroScore, Staphylococcus aureus etiology, and complications (stroke, heart failure, and acute renal failure) were associated with in-hospital mortality in multivariable analyses (P < .05 for all).

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.

Arrhythmic burden in patients with new-onset persistent left bundle branch block after transcatheter aortic valve replacement: 2-year results of the MARE study.

AIMS: We determined the incidence and type of arrhythmias at 2-year follow-up in patients with new-onset persistent left bundle branch block (LBBB) following transcatheter aortic valve replacement (TAVR). METHODS AND RESULTS: Multicentre prospective study including 103 consecutive patients with new-onset persistent LBBB post-TAVR (SAPIEN XT/3: 53; CoreValve/Evolut R: 50). An implantable cardiac monitor (Reveal XT, Reveal Linq) was implanted before hospital discharge and patients had continuous monitoring for up to 2 years. Arrhythmic events were adjudicated in a central core lab. 1836 new arrhythmic events (tachyarrhythmias: 1655 and bradyarrhythmias: 181) occurred at 2 years. Of these, 283 (15%) occurred beyond 1 year (tachyarrhythmias 212, bradyarrhythmias 71) in 33 (36%) patients, without differences between valve type. Most late (>1 year) arrhythmic events were asymptomatic (94%) and led to a treatment change in 17 (19%) patients. A total of 71 late bradyarrhythmias [high-degree atrioventricular block (HAVB): 3, severe bradycardia: 68] were detected in 17 (21%) patients. At 2 years, 18 (17%) patients had received a permanent pacemaker (PPM) or implantable cardiac-defibrillator. PPM implantation due to HAVB predominated in the early phase post-TAVR, with only 1 HAVB event requiring PPM implantation after 1 year. CONCLUSION: Patients with new-onset LBBB post-TAVR exhibited a very high burden of arrhythmic events within the 2 years post-procedure. While new tachyarrhythmic events were homogeneously distributed over time, the vast majority of new HAVB episodes leading to PPM implantation occurred early after the procedure. These results should help to guide the management of this challenging group of patients. (clinicaltrials.gov: NCT02153307).

Changes in outcomes over time in intermediate-risk patients treated for severe aortic stenosis.

BACKGROUND: The advent of transcatheter aortic valve replacement (TAVR) has changed the practice of treating patients with severe aortic stenosis (AS). Heart-Teams have improved their decision-making process to refer patients to the best and safest treatment. The evidence allowed centers to increase funding and TAVR volume and extend indications to different risk categories of patients. This study evaluates the outcomes of intermediate-risk patients treated for severe AS in an academic center. METHODS: Between 2012 and 2019, 812 patients with AS underwent TAVR or surgical aortic valve replacement (SAVR). A propensity score-matching analytic strategy was used to balance groups and adjust for time periods. Outcomes were recorded according to the Society of Thoracic Surgeons Guidelines; the primary outcome being 30-day mortality and the secondary outcomes being perioperative course and complications. RESULTS: No difference in mortality was seen but complications differed: more postoperative transient ischemic attacks, permanent pacemaker implantations, and perivalvular leaks in the transcatheter group, while more acute kidney injuries, atrial fibrillation, delirium, postoperative infections and bleeding, tamponade and need for reoperation in the surgical group as well as a longer hospital length-of-stay. However, over the years, morbidities/mortality decreased for all patients treated for AS. CONCLUSIONS: Data showed an improvement in morbidities/mortality for intermediate-risk patients treated with SAVR or TAVR. Increased funding allowed for a higher TAVR volume by increasing access to this technology. Also, the difference in complications could impact healthcare costs. By incorporating important metrics such as length-of-stay, readmission rates, and complications into decision-making, the Heart-Team can improve clinical outcomes, healthcare economics, and resource utilization.
