Abstract
The new European guidelines for the treatment and management of heart failure (HF) introduce several new recommendations. The revised HF definition has abolished the term “mid-range,” introducing the new concept of “mildly reduced” ejection fraction (EF), which now deserves consideration for therapies previously confined to reduced EF (HF with reduced EF). Following the introduction of sodium-glucose cotransporter 2 inhibitors, physicians should now combine up to 4 different drugs to improve HF with reduced EF prognosis, leading to new issues regarding tolerance and adherence to therapy. Transcatheter treatments of mitral and tricuspid regurgitation are progressively gaining increasing consideration among nonpharmacological strategies. Dedicated therapies for HF with preserved EF are still lacking. These are only some of the most relevant changes provided by European guidelines on HF that are addressed in the present editorial, taking into account the most updated American recommendations.

Abstract
BACKGROUND The severity of MI declined markedly in the last decade, and contemporary patterns of cardiac remodeling after MI are not defined. METHODS We prospectively enrolled community patients with first MI and performed comprehensive two- and three-dimensional echocardiography. Remodeling was defined as left ventricular (LV) end-systolic volume index (ESVI) above American Society of Echocardiography normal values. Remodeling patterns were characterized as an increase in LVESVI or LV end-diastolic volume index (LVEDVI), or both. RESULTS Between 2014 and 2016, 213 patients (63±13 years; 34% women) were enrolled within 3 days after MI (77% non-ST-elevation MI). Acute remodeling was present in 51% of patients. Higher troponin and wall motion score index were associated with greater remodeling (p < 0.001). Atrial annular area, leaflet tenting and papillary muscle areas increased with greater remodeling (p < 0.001). The greater the cardiac remodeling, the lower the LV ejection fraction and global longitudinal strain (p < 0.001). This decrease in LV function was accompanied by stroke volume augmentation and maintenance of cardiac index at the expense of increased LVEDVI. Different remodeling patterns were identified. Cases showing increased LVEDVI and normal LVESVI had smallest infarct size and better hemodynamics compared to cases with augmented LVESVI and normal LVEDVI. CONCLUSION Acute remodeling occurs in more than half of first MI cases and exhibits different patterns defined by cavity size and hemodynamic profile. Acute remodeling is a global phenomenon, which also involves the left atrium and the mitral apparatus.

Abstract
Valvular heart disease (VHD) is a major contributor to loss of physical function, quality of life and longevity. The epidemiology of VHD varies substantially around the world, with a predominance of functional and degenerative disease in high-income countries, and a predominance of rheumatic heart disease in low-income and middle-income countries. Reflecting this distribution, rheumatic heart disease remains by far the most common manifestation of VHD worldwide and affects approximately 41 million people. By contrast, the prevalence of calcific aortic stenosis and degenerative mitral valve disease is 9 and 24 million people, respectively. Despite a reduction in global mortality related to rheumatic heart disease since 1900, the death rate has remained fairly static since 2000. Meanwhile, deaths from calcific aortic stenosis have continued to rise in the past 20 years. Epidemiological data on other important acquired and congenital forms of VHD are limited. An ageing population and advances in therapies make an examination of the changing global epidemiology of VHD crucial for advances in clinical practice and formulation of health policy. In this Review, we discuss the global burden of VHD, geographical variation in the presentation and clinical management, and temporal trends in disease burden.

Abstract
AIMS Transcatheter aortic valve replacement (TAVR) procedural planning requires computed tomography angiography (CTA) which allows for the assessment of left ventricular global longitudinal strain (CTA-LVGLS). There is, however, limited data on the feasibility of CTA-LVGLS, and its prognostic value. This study sought to evaluate the incremental prognostic value of baseline CTA-LVGLS, change in CTA-LVGLS after TAVR, and their association with post-TAVR outcomes. METHODS AND RESULTS A total of 431 patients who underwent multiphasic gated CTA using dual-source system for TAVR planning at baseline and 1-month follow-up were included [median (interquartile range) age, 83 (77-87) years; 44% female, STS-PROM score: 3.3 (2.3-5.1)%, Echo-left ventricular ejection fraction (LVEF): 60 (55-65)%, CTA-LVGLS: -18.0 (-21.6 to -14.2)%, feasible in 97% of patients]. CTA-LVGLS was measured using dedicated feature-tracking software. Over a median follow-up of 19 (13-27) months, 99 endpoints of all-cause death or heart failure hospitalization occurred. The relative hazard of the endpoint increased as baseline CTA-LVGLS worsened with -18.2% as the threshold for higher events (P = 0.005). After adjustment for baseline characteristics, CTA-LVGLS remained associated with the endpoint [hazard ratio (HR) (95% confidence interval, CI), 1.08 (1.03-1.14); P = 0.005] and incrementally improved prognostication (C-index difference, 0.026). Although CTA-LVGLS improved after TAVR [-18.3 (-21.6 to -14.3)% vs. -18.7 (-21.9 to -15.4)%, P < 0.001], patients without CTA-LVGLS improvement had higher risk of the endpoint than those with improvement or preserved baseline global longitudinal strain [HR (95% CI), 1.92 (1.19-3.12); P = 0.008]. CONCLUSIONS In this predominantly low-risk TAVR cohort of patients, mostly with normal LVEF, assessment of CTA-LVGLS is highly feasible improving risk stratification by providing independent and incremental prognostic value over clinical and echocardiographic characteristics.

Abstract
Abstract
Background
The Mitral Regurgitation International Database (MIDA) score is a validated tool for Degenerative Mitral Regurgitation (DMR) management, being able to position a given patient within a continuous spectrum of short and long term mortality. However, whether this score may be applicable and incremental in the entire span of Floppy Mitral Valves (FMV), regardless of DMR severity, remains unsubstantiated.
Methods
The MIDA-Quantitative (MIDA-Q) unprecedented registries include 8187 consecutive patients (age 64±17 years, 45% women, follow-up 5.5±3.4 years) with isolated degenerative mitral valve disease diagnosed at tertiary (European/ North-American/ Middle Eastern) centers in whom DMR severity used both integrative and quantitative grading. The MIDA-Q Score ranged from 0 to 15 depending on accumulating risk factors. Long-term survival overall, under medical management and post-mitral surgery was analysed.
Results
By quantitative grading, MR was no/trivial in 1938 (24%), mild in 1423 (17%), moderate in 2027 (25%) and severe in 2799 (34%), with ERO 0.24±24cm2, RVol 37±35mL, and posterior leaflet prolapse in 49%. MIDA-Q Scores stratified in 8 categories were 0 (score 0, n=851), 1 (score 1–2, n=1301), 2 (score 3–4, n=2043), 3 (score 5–6, n=1581), 4 (score 7–8, n=1273), 5 (score 9–10, n=718), 6 (score 11–12, n=331) and 7 (score 13–15, n=89). In the whole MIDA-Q population (n=8187 patients), 5-year survival under medical management with Scores categories 0–1, 2–4, and 5–7 was 96±1%, 73±1%, and 61±3% respectively (P<0.0001). Five-year mortality ranged from 3% with MIDA Q-score 0 to 95% with MIDA Q-score 13–15 (P<0.0001). After mitral surgery, 1-year mortality with Scores categories 0–1, 2–4, and 5–7 was 0%, 1%, and 6% respectively and 5-year post-operative survival was 99±1%, 94±1%, and 82±2% (all P<0.0001). In models including age, sex and all guideline-provided prognostic markers, the EuroScoreII and the MIDA Score without DMR severity, the MIDA-Q Score provided incremental prognostic information (P<0.001).
Conclusion
This unheard international cohort of patients with FMV and prospective mitral severity quantitative grading, enables for the first time the calculation of a MIDA-Q Score, highly determinant of survival after diagnosis of FMV with any degree of DMR, that may be very useful for mitral valve prolapse management.

Abstract
Abstract
Background
Intracranial aneurysm (IA) has been associated with bicuspid aortic valve (BAV) with prevalence of 6–10% which has led some to recommend routine surveillance for IA in BAV patients. Higher incidence of IA in BAV could signal towards systemic arteriopathy beyond the thoracic aorta. With CoA as an independent risk factor for IA formation, it is currently uncertain if the association between IA and BAV reflects the association of BAV and CoA, or the result of BAV-related systemic arterial changes.
Purpose
Despite this association, 2 small studies suggest no increased risk of the most important patient outcome: aneurysmal sub-arachnoid hemorrhage (aSAH). Our primary aim was identifying the prevalence of BAV in aSAH patients and compare it with that of a control group without aSAH. Secondary aims included neurologic outcomes of aSAH and anatomical characteristics of IA in BAV, and final disposition and outcome.
Methods
Patients (>18 years age) with an accurate diagnosis of aSAH and at least one echocardiogram in the system between January 2000-December 2019 were identified from a prospectively maintained registry of aSAH admissions. Controls, without a diagnosis of SAH ever, were age- and gender-matched (1:2 cases:controls). BAV prevalence was echocardiographically-confirmed in all patients. Severity of aSAH was categorized using the modified Fisher (mFisher) and the World Federation of Neurological Scale (WFNS).
Results
A total of 488 aSAH cases and 990 controls were included in the final analysis with confirmed aortic valve status. The prevalence of BAV in aSAH patients was 1.2% (6/488) vs 3.5% (35/990) in controls, p=0.01. None of the aSAH cases were noted to have CoA, whereas 3 (0.3%; p=0.12) control patients had presence of both BAV and CoA. Within aSAH patients, BAV+aSAH were noted to be younger than tricuspid aortic valve (TAV)+aSAH (56±11 vs 68±14; p=0.03). Aneurysm size was smaller in the BAV+aSAH group (5±2 vs 7±4 in TAV+aSAH; p=0.31). The severity of the bleed was lesser in BAV+aSAH than TAV+aSAH (mFisher grade >2 50% vs 74%; p=0.19, WFNS grade >3 17% vs 36%; p=0.43) which is clinically significant. The BAV+aSAH group had higher disposition rate to home (67% vs 39%; p=0.21) with no difference in in-hospital mortality rates (17% vs 18%; p=0.93). BAV had lower odds on univariate and multivariate analyses adjusted for age/sex/body mass index (OR 0.33 [CI 0.14–0.81]; p=0.01, OR 0.23 [CI 0.08–0.65]; p=0.01) of presenting with aSAH.
Conclusion
Within a large prospective registry with accurate aSAH diagnoses, we found 3-times lower prevalence of echocardiographically-confirmed BAV as compared to non-aSAH controls. We observed 3-times higher prevalence of BAV in controls than among aSAH cases. In addition, size of intracranial aneurysms was clinically smaller in BAV patients, and the severity of SAH was significantly lesser in BAV from a clinical standpoint. Our findings argue against routine surveillance for IA in BAV patients without CoA.

Abstract
This International Consensus Classification and Nomenclature for the congenital bicuspid aortic valve condition recognizes 3 types of bicuspid valves: 1. The fused type (right-left cusp fusion, right-non-coronary cusp fusion and left-non-coronary cusp fusion phenotypes); 2. The 2-sinus type (latero-lateral and antero-posterior phenotypes); and 3. The partial-fusion (forme fruste) type. The presence of raphe and the symmetry of the fused type phenotypes are critical aspects to describe. The International Consensus also recognizes 3 types of bicuspid valve-associated aortopathy: 1. The ascending phenotype; 2. The root phenotype; and 3. Extended phenotypes. © 2021 Jointly between the RSNA, the European Association for Cardio-Thoracic Surgery, The Society of Thoracic Surgeons, and the American Association for Thoracic Surgery.

Abstract
BACKGROUND The dynamic consequences of mitral annular disjunction (MAD) on the mitral apparatus and the left ventricle remain unclear and are crucial in the context of mitral surgery. Thus, the aim of this study was to assess mitral valvular, annular, and ventricular dynamics in mitral valve prolapse (MVP) stratified by presence of MAD. METHODS In 61 patients (mean age, 62 ± 11 years; 25% women) with MVP and severe mitral regurgitation undergoing mitral surgery between 2009 and 2016, valvular and annular dimensions and dynamics by two-dimensional transthoracic and three-dimensional transesophageal echocardiography and left ventricular dimensions and dynamics were analyzed stratified by presence of MAD before and after surgery. RESULTS MAD (mean, 8 ± 3 mm) was diagnosed in 27 patients (44%; with a mean effective regurgitant orifice area of 0.55 ± 0.20 cm2 and similar to patients without MAD), more frequently in bileaflet prolapse (52% vs 18% in patients without MAD, P = .004), consistently involving P2 (P = .005). Patients with MAD displayed larger diastolic annular areas (mean, 1,646 ± 410 vs 1,380 ± 348 mm2), circumferences (mean, 150 ± 19 vs 137 ± 16 mm), and intercommissural diameters (mean, 48 ± 7 vs 43 ± 6 mm) compared with those without MAD (P ≤ .008 for all). Dynamically, mid- and late systolic excess intercommissural diameter, annular area, and circumference enlargement were associated with MAD (P ≤ .01 for all). MAD was also associated with dynamically annular slippage, larger prolapse volume and height (P ≤ .007), and larger leaflet area (mean, 2,053 ± 620 vs 1,692 ± 488 mm2, P = .01). Although patients with MAD compared with those without MAD showed similar ejection fractions (mean, 65 ± 5% vs 62 ± 8%, respectively, P = .10), systolic basal posterior thickness was increased in patients with MAD (mean, 19 ± 2 vs 15 ± 2 mm, P < .001), with higher systolic thickening of the basal posterior wall (mean, 74 ± 27% vs 50 ± 28%) and higher ratio of basal wall thickness to diameter (P ≤ .01 for both). However, after mitral repair, MAD disappeared, and LV diameter, wall thickness, and wall thickening showed no difference between patients with MAD and those without MAD (P ≥ .10 for all). CONCLUSIONS MAD in patients with MVP involves a predominant phenotype of bileaflet MVP and causes profound annular dynamic alterations with considerable expansion and excess annular enlargement in systole, potentially affecting leaflet coaptation. MAD myocardial and annular slippage simulates vigorous left ventricular function without true benefit after surgical annular suture. Thus, although MAD does not hinder the feasibility and quality of valve repair, it requires careful suture of ring to ventricular myocardium, lest it persist postoperatively.

Abstract
Objectives Despite coherent guidelines, management of functional tricuspid regurgitation (FTR) consequences on outcome in the context of degenerative mitral regurgitation (DMR) remains controversial due to lacking series of large magnitude with rigorous application of tricuspid guidelines and strict long-term echocardiographic follow-up. Thus, we aimed at gathering such a cohort to examine outcomes of patients undergoing DMR surgery following tricuspid surgery guidelines. Methods All consecutive patients with isolated DMR 2005-2015 operated on with baseline FTR assessment and tricuspid annulus diameter measurement were identified. Operative complications, postoperative tricuspid regurgitation incidence, and survival were assessed overall and stratified by guideline-based tricuspid annuloplasty (TA) indication (severe FTR or tricuspid annulus diameter ≥40 mm). Results Among 441 patients with DMR undergoing mitral repair (66 ± 13 years, 30% female, ejection fraction 66 ± 10%, systolic pulmonary artery pressures 39 ± 12 mm Hg) followed 6 [3-9] years, patients with TA (n = 234, 53%) had generally similar presentation versus without TA (n = 207, 47%; all P ≥ .2) except for more atrial fibrillation and larger left ventricle (both P ≥ .0003). Patients with TA showed longer bypass time, more maze procedures (all P ≤ .001), but hospital stay, renal-failure, pacemaker implantation, and operative mortality (overall 0.9%) were comparable (all P ≥ .2). Postoperative incidence of moderate/severe FTR (0% at 1 year) became over time greater among patients without TA (5-year 8% [4%-13%] vs 3% [1%-11%] and 10-year 10% [6%-16%] vs 4% [1%-16%], P = .01). Survival (95% confidence interval) throughout follow-up was 85% (77%-89%) at 10 years, with hazard ratio 0.57 (0.29-1.10), P = .09. for patients with TA versus without. Conclusions In this large surgical DMR cohort, guideline-based FTR management was safe and effective. While long-term mortality did not reach significance, postoperative incidence of moderate/severe FTR, overall low, was nevertheless greater in patients who did not appear to require TA at surgery and linked to tricuspid annular dimension. Thus, future multicenter prospective cohorts with long-term follow-up are warranted to re-examine thresholds for TA performance and impact on survival.

Abstract
OBJECTIVE To examine contemporary clinical differences between men and women with hemodynamically significant chronic aortic regurgitation (AR). PATIENTS AND METHODS We retrospectively identified 1072 consecutive patients with moderate to severe or severe AR diagnosed between February 21, 2004, and April 29, 2019. Echocardiographic data, aortic valve surgical intervention (AVS), and all-cause death were analyzed. RESULTS At baseline, the 189 women in the study group were older than the 883 men (mean ± SD age, 64±18 years vs 58±17 years), had more advanced symptoms, and had larger left ventricular end-systolic dimension index (LVESDi) (all P<.001) despite similar AR severity. An LVESDi of greater than 20 mm/m2 was noted in 60 of 92 asymptomatic women (65%) vs 225 of 559 asymptomatic men (40%) (P<.001). Median follow-up was 5.6 years (interquartile range, 2.5 to 10.0 years). Female sex was associated with less AVS (P=.009), and overall 10-year survival was better in men (76%±2%) than in women (64%±5%) (P=.004). However, 10-year post-AVS survival was similar between the sexes (P=.86), and women had better left ventricular reverse remodeling than men regarding end-diastolic dimension (P=.02). Multivariable independent predictors of death were age, advanced symptoms, LVESDi, ejection fraction, and AVS (all P≤.03) but not female sex. When compared with the age-matched US population, women exhibited a 1.3-fold increased relative risk of death (P=.0383) while men had similar survival (P=.11). CONCLUSION In contemporary practice, women with AR continue to exhibit an overall survival penalty not related to female sex but to late referral markers, including more advanced symptoms, larger LVESDi, and less AVS. Nonetheless, women in our study exhibited outstanding post-AVS left ventricular remodeling and had good post-AVS survival, a step forward toward closing the sex-related mortality gap. The high percentage of LVESDi of 20 mm/m2 or greater in asymptomatic women represents a window of opportunity for advanced-symptom prevention and timely AR surgical correction that may close the mortality gap.

Abstract
This International evidence-based nomenclature and classification consensus on the congenital bicuspid aortic valve and its aortopathy recognizes 3 types of bicuspid aortic valve: 1. Fused type, with 3 phenotypes: right-left cusp fusion, right-non cusp fusion and left-non cusp fusion; 2. 2-sinus type with 2 phenotypes: Latero-lateral and antero-posterior; and 3. Partial-fusion or forme fruste. This consensus recognizes 3 bicuspid-aortopathy types: 1. Ascending phenotype; root phenotype; and 3. extended phenotypes.

Abstract
This International Consensus Classification and Nomenclature for the congenital bicuspid aortic valve condition recognizes 3 types of bicuspid valves: 1. The fused type (right-left cusp fusion, right-non-coronary cusp fusion and left-non-coronary cusp fusion phenotypes); 2. The 2-sinus type (latero-lateral and antero-posterior phenotypes); and 3. The partial-fusion (forme fruste) type. The presence of raphe and the symmetry of the fused type phenotypes are critical aspects to describe. The International Consensus also recognizes 3 types of bicuspid valve-associated aortopathy: 1. The ascending phenotype; 2. The root phenotype; and 3. Extended phenotypes.

Abstract
OBJECTIVES The aim of this study was to assess in patients with mitral valve prolapse (MVP) mitral annular disjunction (MAD) prevalence, phenotypic characteristics, and long-term outcomes (clinical arrhythmic events and excess mortality). BACKGROUND Clinical knowledge regarding MAD of MVP remains limited and controversial, and its potential link with untoward outcomes is unsubstantiated. METHODS A cohort of 595 (278 women, mean age 61 ± 16 years) consecutive patients with isolated MVP, with comprehensive clinical, rhythmic, Doppler echocardiographic, and consistent MAD assessment, were examined. MAD prevalence, associated MVP phenotypes, and outcomes (survival, clinical arrhythmic events) starting at diagnostic echocardiography were analyzed. To balance important baseline differences, propensity scoring matching was conducted among patients with and those without MAD. RESULTS The presence of MAD was common (n = 186 [31%]) in patients with MVP, generally in younger patients, and was not random but was independently associated with severe myxomatous disease involving bileaflet MVP and marked leaflet redundancy (both P ≤ 0.0002). The presence of MAD was also independently associated with a larger left ventricle (P = 0.005). Age-matched cohort survival after MVP diagnosis was not worse with MAD (10-year survival 93% ± 2% for patients without MAD and 97% ± 1% for those with MAD; P = 0.40), even adjusted comprehensively for MVP characteristics (P = 0.80) and accounting for time-dependent mitral surgery (P = 0.60). During follow-up, 170 patients had clinical arrhythmic events (ventricular tachycardia, n = 159; arrhythmia ablation, n = 14; cardioverter-defibrillator implantation, n = 14; sudden cardiac death, n = 3). MAD was independently associated with higher risk for arrhythmic events (adjusted HR: 2.60; 95% CI: 1.87-3.62; P < 0.0001). The link between MAD and arrhythmic events persisted with time-dependent mitral surgery (adjusted HR: 2.54; 95% CI: 1.84-3.50; P < 0.0001), was strong under medical management (adjusted HR: 3.21; 95% CI: 2.03-5.06; P < 0.0001) but was weaker after mitral surgery (adjusted HR: 2.07; 95% CI: 1.24-3.43; P = 0.005). CONCLUSIONS This large cohort with MVP comprehensively characterized shows that MAD is frequent at MVP diagnosis and is strongly linked to advanced myxomatous degeneration. The presence of MAD was independently associated with long-term excess incidence of clinical arrhythmic events. However, within the first 10 years post-diagnosis, MAD was not linked to excess mortality, and although reassurance should be provided from the survival point of view, careful monitoring for arrhythmias is in order for MAD.

Abstract
ObjectiveTo compare the prevalence and patterns of anomalous coronary artery origin from the opposite sinus (ACAOS) in patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV).MethodsRetrospective review of consecutive patients with surgically excised BAV and TAV was performed from 1994 to 2015. Clinical notes, echocardiograms, coronary angiograms, CT angiographies, and pathology reports were reviewed. ACAOS included right coronary artery from the left cusp, left circumflex artery from the right cusp and left main or left anterior descending artery from the right cusp.Results2371 (years 1994–2015) and 1679 (years 2009–2015) consecutive patients with pathology-confirmed BAV and TAV, respectively, and defined preoperative coronary anatomy were identified. A left dominant coronary circulation was present in 386 (18%) patients with BAV and 179 (11%) patients with TAV (p<0.001). ACAOS was identified in 43 (1.8%) patients with BAV and 15 (0.9%) patients with TAV, p=0.02. Among patients with BAV and ACAOS, the most common phenotype was right-left fusion (n=34, 79%) with present raphe (n=36, 84%), with no association between BAV phenotype and ACAOS type. On multivariate analysis, BAV status and size of the mid-ascending aorta were independently associated with ACAOS (OR 3.29; CI 1.26 to 8.6; p=0.02; OR 0.93; CI 0.87 to 0.98; p=0.01; respectively). Only two patients with ACAOS, one with BAV and one with TAV, had a perioperative coronary ischaemic event.ConclusionsThe prevalence of the potentially malignant ACAOS is significantly higher (threefold higher odds) in patients with BAV as compared with TAV, yet remains uncommon in absolute terms. Most patients with BAV and ACAOS had right-left cusp fusion and present raphe. Perioperative coronary events are rare in patients with ACAOS.
