BACKGROUND: Thromboembolic events, particularly strokes, remain a major complication of transcatheter aortic valve replacement (TAVR). Embolic protection devices have failed to show significant clinical benefit in large randomized clinical trials. Aortic wall thrombus (AWT) is often observed on multidetector computed tomography during TAVR work-up, but its prognostic significance is uncertain. OBJECTIVES: This study sought to evaluate the association between the presence of AWT and the incidence of thromboembolic outcomes in patients undergoing transfemoral (TF) TAVR for severe aortic stenosis. METHODS: This was a prospective cohort study of consecutive patients who underwent TF TAVR for severe aortic stenosis between January 2011 and April 2022. A dedicated scale (range: 0-10) was qualitatively used to assess AWT. The primary outcome was a composite of procedural thromboembolic events defined as ischemic stroke, blue toe syndrome, bowel ischemia, or other solid organ infarction. The secondary endpoints were ischemic strokes and procedural death. RESULTS: Of the 641 patients included, severe AWT (score ≥8) was identified in 73 (11.4%). The presence of severe AWT was strongly associated with an increase in the primary outcome (OR: 8.48; 95% CI: 3.36-21.40; P < 0.001). This relationship persisted following multivariable analysis, which adjusted for comorbidities and procedural characteristics. The presence of severe AWT was also found to be associated with an increased incidence of stroke and procedural death (OR: 5.66; 95% CI: 2.00-15.30; P = 0.002 and OR: 4.66; 95% CI: 1.80-11.30; P = 0.002, respectively). CONCLUSIONS: The presence of severe AWT on preprocedural multidetector computed tomography is strongly associated with thromboembolic complications including stroke and mortality after TF TAVR.

BACKGROUND AND AIMS: Intra-pocket ultrasound-guided axillary vein puncture (IPUS-AVP) for venous access in implantation of transvenous cardiac implantable electronic devices (CIED) is uncommon due to the lack of clinical evidence supporting this technique. This study investigated the efficacy and early complications of IPUS-AVP compared to the standard method using cephalic vein cutdown (CVC) for CIED implantation. METHODS: ACCESS was an investigator-led, interventional, randomized (1:1 ratio), monocentric, controlled superiority trial. A total of 200 patients undergoing CIED implantation were randomized to IPUS-AVP (n = 101) or CVC (n = 99) as a first assigned route. The primary endpoint was the success rate of insertion of all leads using the first assigned venous access technique. The secondary endpoints were time to venous access, total procedure duration, fluoroscopy time, X-ray exposure, and complications. Complications were monitored during a follow-up period of three months after procedure. RESULTS: IPUS-AVP was significantly superior to CVC for the primary endpoint with 100 (99.0%) vs. 86 (86.9%) procedural successes (P = .001). Cephalic vein cutdown followed by subclavian vein puncture was successful in a total of 95 (96.0%) patients, P = .21 vs. IPUS-AVP. All secondary endpoints were also significantly improved in the IPUS-AVP group with reduction in time to venous access [3.4 vs. 10.6 min, geometric mean ratio (GMR) 0.32 (95% confidence interval, CI, 0.28-0.36), P < .001], total procedure duration [33.8 vs. 46.9 min, GMR 0.72 (95% CI 0.67-0.78), P < .001], fluoroscopy time [2.4 vs. 3.3 min, GMR 0.74 (95% CI 0.63-0.86), P < .001], and X-ray exposure [1083 vs. 1423 mGy.cm², GMR 0.76 (95% CI 0.62-0.93), P = .009]. There was no significant difference in complication rates between groups (P = .68). CONCLUSIONS: IPUS-AVP is superior to CVC in terms of success rate, time to venous access, procedure duration, and radiation exposure. Complication rates were similar between the two groups. Intra-pocket ultrasound-guided axillary vein puncture should be a recommended venous access technique for CIED implantation.

BACKGROUND: Secondary forms and hypertension-mediated organ damage (HMOD) may differ between younger and older hypertensive patients. The aim of the present study was to explore the specificity of HMOD and secondary forms in patients ≥ 65 years in comparison to younger ones in a contemporary cohort. METHODS: We analysed 938 patients recruited between 2004 and 2014 (Cardiology department, Croix-Rousse Hospital, Lyon) who had at baseline HMOD and secondary forms screening among them 190 were ≥ 65 years. RESULTS: The mean (2.1 ± 0.8 vs. 1.2 ± 0.9, P < 0.001) and frequency of HMOD (96.3% vs. 72.9%, P < 0.001) was higher in patients ≥ 65 years than younger ones. Carotid femoral pulse wave velocity > 10 m/s was the most frequent HMOD in patients ≥ 65 years (90.1%), while echocardiographic left ventricular hypertrophy was the most common in the younger patients (45.0%). Among ECG left ventricular indexes, only R wave in aVL lead was significantly more frequently observed in patients ≥ 65 years (32.6%) than in younger ones (19.0%, P < 0.001). The frequency of secondary hypertension was not significantly different between younger and older patients (respectively; 30.5% vs. 27.8%, P = 0.487). The most frequent aetiology was primary aldosteronism regardless of age, followed by renovascular hypertension (6.3% vs. 3.3%, P = 0.038). Among older patients, 3.2% were treated with adrenalectomy and 6.3% with percutaneous transluminal renal angioplasty. CONCLUSION: Extensive screening of HMOD in older patients may be questionable as nearly all patients had one; aetiology must however be explored as a third of older patients had a secondary form.
RESUMEN
Aims: After transcatheter aortic valve replacement (TAVR), cardiovascular and non-cardiovascular comorbidities may offset the survival benefit from the procedure. We aimed to describe the relationships between that benefit and patient comorbidities. Methods and results: The study pooled two European cohorts of patients with severe aortic stenosis (AS-pooled): one with patients who underwent (cohort of AS patients treated by TAVR, N = 233) and another with patients who did not undergo TAVR (cohort of AS patients treated medically; N = 291). The investigators collected the following: calcification prognostic impact (CAPRI) and Charlson scores for cardiovascular and non-cardiovascular comorbidities, activities of daily living (ADL)/instrumental activities of daily living (IADL) scores for frailty as well as routine Society of Thoracic Surgeons (STS) score and Logistic Euroscore. Unlike ADL/IADL scores, CAPRI and Charlson scores were found to be independent predictors of 1-year all-cause death in the AS-pooled cohort, with and without adjustment for STS score or Logistic Euroscore; they were thus retained to define a three-level prognostic scale (good, intermediate, and poor). The survival benefit from TAVR-vs. no TAVR-was stratified according to these three prognosis categories. The beneficial effect of TAVR on 1-year all-cause death was significant in patients with good and intermediate prognosis, hazard ratio (95% confidence interval): 0.36 (0.18; 0.72) and 0.32 (0.15; 0.67). That effect was reduced and not statistically significant in patient with poor prognosis [0.65 (0.22; 1.88)]. Conclusion: The study showed that, beyond a given comorbidity burden (as assessed by CAPRI and Charlson scores), the probability of death within a year was high and poorly reduced by TAVR. This indicates the futility of TAVR in patients in the poor prognosis category.
RESUMEN
PURPOSE OF REVIEW: The identification of BRAF mutation prompted the development of new class of targeted therapy for treating melanoma: BRAF inhibitors and MEK inhibitors. Cardiovascular events have been reported with these treatments and could counterbalance their long-term maintenance. RECENT FINDINGS: LVEF decrease due to BRAF and MEK inhibitors appears fairly common (10%) but usually not severe, without impact on patient outcomes. To date, no treatment options have been tested to prevent or to treat a decrease of LVEF associated with BRAF and MEK inhibitors. QTc prolongation was observed in 3% and arterial hypertension in 20% during treatment but only one-third of cases required a therapeutic change. BRAF and MEK inhibitors have revolutionized the management and the prognosis of melanoma patients. Cardio-oncology units may be useful for a better care of potential cardiac toxicity and particularly to inappropriately avoid discontinuing BRAF and MEK inhibitors.

AIMS: Current European guidelines recommend the SCORE to estimate 10-year cardiovascular mortality in patients with moderate/low cardiovascular risk. SCORE was derived from the general population. The objective of this study was to investigate the estimated 10-year cardiovascular mortality according to the SCORE in a historic and a contemporary cohort of hypertensive patients. METHODS AND RESULTS: After exclusion of secondary prevention and diabetes, 3086 patients were analysed in the OLD-HTA (1969-90) and 1081 in the NEW-HTA (1997-2014) Lyon cohorts. SCORE was calculated using the low and high cardiovascular risk equations and charts, and patients classified as being at low (0%), moderate (1-4%), high (5-9%), and very high (≥10%) risk. In the OLD-HTA cohort, 10-year cardiovascular mortality was higher (1.2%, 5.5%, 17.7%, and 27.0%) than that predicted by the low-risk equation (0%, 1.7%, 6.4%, and 14.8%). In the NEW-HTA cohort, similar results were observed (1.1%, 4.7%, 15.1%, and 15.2% vs. 0%, 1.9%, 6.2%, and 11.7%, respectively). Using the high-risk equation, mortality was underestimated in both cohorts, but the difference was smaller. The diagnostic performance of the high-risk equation was lower than the low-risk equation in both cohorts, considering the SCORE as a continuous or a categorical variable (Likelihood ratio test P < 0.05 for all comparisons in OLD-HTA). Similar results were obtained using SCORE charts. CONCLUSION: SCORE underestimates the 10-year cardiovascular mortality risk in hypertensive patients in a historic cohort and in a contemporary one. The algorithm to predict cardiovascular mortality in hypertensive patients needs an update given new information since its creation.

AIMS: This study determined whether the improvements in hypertension management over the last five decades have influenced subjects' prognosis. METHODS AND RESULTS: The study considered 5693 eligible subjects seen January 1969 to February 1991 (follow-up until December 2003) or January 1995 to October 2014 (follow-up until July 2016) in an all-grade hypertension reference centre. Missing data or incomplete follow-ups led to exclude 1036 subjects (18%). The outcome was all-cause death. An adjusted modelling of the excess mortality rate assessed subjects' net survival over five inclusion periods to allow for the increase in life expectancy of the general population during the same periods. The analysis of 4657 records (mean age: 47 years; 43.2% women) showed that the proportion of subjects with grade 3 hypertension decreased significantly from 43.3% (1142) to only 6.3% (22) over the five periods and that the net survival improved in men and women regardless of the hypertension grade; i.e. the gain in net survival at 15 years was estimated at 12.3% (95% confidence interval: 8.1-22.3). The 15-year restricted mean survival was estimated at 13 years over the first period and 14.8 years over the last period, which is nearly a 2-year gain in life expectancy at 15 years. CONCLUSION: Since the 70s and the advent of modern management, the excess mortality of hypertensive subjects (vs. the general population) was markedly reduced. Within a context of trivialization of blood pressure measurement and reluctance to long-term treatments, physicians should consider this advantage and use it to promote blood pressure control.

AIMS: In low-gradient aortic stenosis (LGAS), the high valvulo-arterial impedance observed despite low valvular gradient suggests a high vascular load. Thoracic aortic calcifications (TACs) and valvular aortic calcifications (VACs) are, respectively, surrogates of aortic load and aortic valvular gradient. The aim of this study was to compare the respective contributions of TAC and VAC on 3-year cardiovascular (CV) mortality following TAVI in LGAS vs. high-gradient aortic stenosis (HGAS) patients. METHODS AND RESULTS: A total of 1396 consecutive patients were included. TAC and VAC were measured on the pre-TAVI CT-scan. About 435 (31.2%) patients had LGAS and 961 (68.8%) HGAS. LGAS patients were more prone to have diabetes, coronary artery disease (CAD), atrial fibrillation (AF), and lower left ventricular ejection fraction (LVEF), P<0.05 for all. During the 3 years after TAVI, 245(17.8%) patients experienced CV mortality, 92(21.6%) in LGAS and 153(16.2%) in HGAS patients, P=0.018. Multivariate analysis adjusted for age, gender, diabetes, AF, CAD, LVEF, renal function, vascular access, and aortic regurgitation showed that TAC but not VAC was associated with CV mortality in LGAS, hazard ratio (HR) 1.085 confidence interval (CI) (1.019-1.156), P=0.011, and HR 0.713 CI (0.439-1.8), P=0.235; the opposite was observed in HGAS patients with VAC but not TAC being associated with CV mortality, HR 1.342 CI (1.034-1.742), P=0.027, and HR 1.015 CI (0.955-1.079), P=0.626. CONCLUSION: TAC plays a major prognostic role in LGAS while VAC remains the key in HGAS patients. This confirms that LGAS is a complex vascular and valvular disease.

BACKGROUND: Endovascular renal denervation reduces blood pressure in patients with mild-to-moderate hypertension, but its efficacy in patients with true resistant hypertension has not been shown. We aimed to assess the efficacy and safety of endovascular ultrasound renal denervation in patients with hypertension resistant to three or more antihypertensive medications. METHODS: In a randomised, international, multicentre, single-blind, sham-controlled trial done at 28 tertiary centres in the USA and 25 in Europe, we included patients aged 18-75 years with office blood pressure of at least 140/90 mm Hg despite three or more antihypertensive medications including a diuretic. Eligible patients were switched to a once daily, fixed-dose, single-pill combination of a calcium channel blocker, an angiotensin receptor blocker, and a thiazide diuretic. After 4 weeks of standardised therapy, patients with daytime ambulatory blood pressure of at least 135/85 mm Hg were randomly assigned (1:1) by computer (stratified by centres) to ultrasound renal denervation or a sham procedure. Patients and outcome assessors were masked to randomisation. Addition of antihypertensive medications was allowed if specified blood pressure thresholds were exceeded. The primary endpoint was the change in daytime ambulatory systolic blood pressure at 2 months in the intention-to-treat population. Safety was also assessed in the intention-to-treat population. This study is registered with ClinicalTrials.gov, NCT02649426. FINDINGS: Between March 11, 2016, and March 13, 2020, 989 participants were enrolled and 136 were randomly assigned to renal denervation (n=69) or a sham procedure (n=67). Full adherence to the combination medications at 2 months among patients with urine samples was similar in both groups (42 [82%] of 51 in the renal denervation group vs 47 [82%] of 57 in the sham procedure group; p=0·99). Renal denervation reduced daytime ambulatory systolic blood pressure more than the sham procedure (-8·0 mm Hg [IQR -16·4 to 0·0] vs -3·0 mm Hg [-10·3 to 1·8]; median between-group difference -4·5 mm Hg [95% CI -8·5 to -0·3]; adjusted p=0·022); the median between-group difference was -5·8 mm Hg (95% CI -9·7 to -1·6; adjusted p=0·0051) among patients with complete ambulatory blood pressure data. There were no differences in safety outcomes between the two groups. INTERPRETATION: Compared with a sham procedure, ultrasound renal denervation reduced blood pressure at 2 months in patients with hypertension resistant to a standardised triple combination pill. If the blood pressure lowering effect and safety of renal denervation are maintained in the long term, renal denervation might be an alternative to the addition of further antihypertensive medications in patients with resistant hypertension.

OBJECTIVES: Patients with overt and subclinical Cushing's syndrome frequently develop hypertension, metabolism disorders, and atherosclerotic lesions. The aim of the present study was to test the association between cortisol and blood pressure (BP), organ damage, and metabolic parameters in hypertensive patients without hypercortisolism. METHODS: After exclusion of patients treated with corticosteroids or with Cushing's syndrome, the cohort included 623 hypertensive patients (meanâ±âSD age 50.3â±â15.4âyears, 50.9% men, median 24-h BP 146/88âmmHg) with an extended work-up (lipid profile, hypertension-mediated organ damage). Cortisol secretion was assessed by plasma cortisol at 0800 and 1600 h, and by 24-h urinary free cortisol (24âh UFC) normalized if required to urine creatinine (UFC/U creat). RESULTS: Plasma cortisol at 1600 h, 24âh-UFC, and UFC/U creat were significantly and positively correlated with daytime, night-time, and 24-h SBP; plasma cortisol at 0800 h was not associated with BP. The strongest correlations were observed in the subgroup of aged more than 50âyears (correlation coefficients between 0.23 and 0.28). These correlations remained after adjustment on plasma aldosterone. Metabolic parameters were weakly associated with cortisol. Arterial stiffness (central pulse pressure and pulse wave velocity), plasma NT-proBNP, and microalbuminuria were significantly correlated with 24âh UFC, UFC/U creat, and plasma cortisol at 1600âh. CONCLUSION: Cortisol influences weakly the level of BP independently from plasma aldosterone in hypertensive patients, particularly in older patients, and that there was weak association with HMOD. It may, therefore, be of interest to test specific treatments targeting cortisol excess in selected hypertensive patients.

Intravenous mineralocorticoid receptor antagonists (MRAs) have been used in some centers for decades to reduce the risk of hypokalemia and boost diuresis in acutely decompensated heart failure (ADHF). We report the well-tolerated use of intravenous MRAs as a rescue procedure in 3 patients admitted for ADHF with important diuretic resistance. Undertaking trials evaluating the effect of this therapeutic strategy in ADHF could represent a promising avenue.

In patients who underwent transcatheter aortic valve implantation (TAVI), vascular disease is associated with increased risk of mortality. Thoracic aortic calcification (TAC), an objective surrogate of vascular disease, could be a predictor of mortality after TAVI. We aimed to analyze the association between TAC burden and 1-year all-cause mortality in patients who underwent TAVI in a US population. From July 2015 through July 2017, a retrospective review of TAVI procedures was performed at Baylor Scott & White-The Heart Hospital, Plano, Texas. Patients were analyzed for comorbidities, cardiac risk factors, and 30-day and 1-year all-cause mortality. Restricted cubic splines analysis was used to define low, moderate, and high TAC categories. The association between TAC and survival was evaluated using unadjusted and adjusted Cox models. A total of 431 TAVI procedures were performed, of which TAC was measured in 374 (81%) patients. Median (interquartile range) age was 82 (77, 87) years, and 51% were male. Median (interquartile range) STS PROM was 5.6 (4.1, 8.2) %. Overall 30-day and 1-year all-cause mortality was 1% and 10%, respectively. TAC was categorized as low (<1.6 cm3), moderate (1.6 to 2.9 cm3), and high (>2.9 cm3). At 1 year, all-cause mortality was 16% in patients with high TAC compared with 6% in the low and moderate TAC categories (pâ¯=â¯0.008). Unadjusted and adjusted Cox regression analysis showed a significant increase in mortality for patients with high TAC compared with low TAC (hazard ratio 2.98, 95% confidence interval [1.34-6.63]), but not significant compared with moderate TAC group. TAC is a predictor of late mortality after TAVI. In conclusion, adding TAC to preoperative evaluation may provide an objective, reproducible, and potentially widely available tool that can help in shared decision-making.

BACKGROUND: The number of very old patients admitted to intensive care units for acute coronary syndromes has increased gradually, but these patients are under-represented in randomized clinical trials. AIM: The aim of this study was to analyse mortality of nonagenarians compared with octogenarians admitted to an intensive care unit for acute coronary syndromes, to describe their management and to identify prognostic factors. METHODS: Patients aged≥80years admitted to an intensive care unit (Croix-Rousse University Hospital, Lyon) with a diagnosis of acute coronary syndrome from 1 January 2013 to 31 December 2016 were included retrospectively. After exclusion of type 2 acute coronary syndromes, the data for 311 octogenarians and 92 nonagenarians were analysed using Kaplan-Meier curves and a multivariable Cox regression model. RESULTS: More than 70% of patients received renin-angiotensin-system blockers, beta-blockers and statins, without significant difference between nonagenarians and octogenarians. Nonagenarians were treated significantly less frequently with ticagrelor than octogenarians (P=0.028). Overall, 97.8% of patients had a coronary angiogram, and 80.4% underwent percutaneous coronary intervention. At 5-year follow-up, the survival rate was 62.8% for nonagenarians compared with 73.1% for octogenarians (P=0.007), but no significant difference was observed for cardiovascular mortality (P=0.17). Global Registry of Acute Coronary Events (GRACE) score and increased age were significantly associated with higher mortality rate, while renin-angiotensin-system blockers, statins and ticagrelor were protective factors. CONCLUSIONS: Although overall mortality was higher in patients aged≥90 years compared with those aged<90years with acute coronary syndromes, the overall survival reported here is acceptable. In addition to the effect of age, the difference in prognosis according to age may be explained, in part, by a non-optimal treatment strategy for older patients.

BACKGROUNDS: Data on optimal antiplatelet therapy in patients undergoing stenting of the proximal left anterior descending artery (LAD) are limited. METHODS: This is a post-hoc analysis of the GLOBAL LEADERS trial, a prospective, multi-center, randomized controlled trial, comparing the experimental strategy (1-month dual anti-platelet therapy [DAPT] followed by 23-month ticagrelor monotherapy) with the reference regimen (12-month DAPT followed by 12-month aspirin monotherapy) in relation to stenting of the proximal LAD. The primary endpoint was the composite of all-cause death or new Q-wave myocardial infarction (MI) and key secondary safety endpoint was Bleeding Academic Research Consortium (BARC) type 3 or 5 bleeding at two years. RESULTS: Among 15,845 patients included in the analysis, 3823 (23.9%) patients underwent stenting of the proximal LAD, while 12,022 (75.2%) did not. In the proximal LAD stenting group, there was no significant difference in the risk of the primary endpoint between the two antiplatelet strategies (3.38% vs. 3.93%; hazard ratio [HR]:0.86; 95% CI:0.62-1.20; Pinteraction = 0.951). However, the risk of any MI (2.63% vs. 3.88%; HR:0.68; 95% CI:0.47-0.97; Pinteraction = 0.015) and any revascularization (7.84% vs. 9.94%; HR:0.78; 95% CI:0.63-0.97; Pinteraction = 0.058) was significantly lower in the experimental strategy group, while demonstrating a similar risk of BARC type 3 or 5 bleeding between the two antiplatelet strategies (1.93% vs. 1.99%; HR:0.98; 95% CI:0.62-1.54; Pinteraction = 0.981). CONCLUSIONS: The present study showed patients having stenting to the proximal LAD could potentially benefit from the experimental strategy with lower ischaemic events without a trade-off in major bleeding at two years.

BACKGROUND: How coronavirus 2019 (COVID-19) is affecting management of myocardial infarction is a matter of concern, as medical resources have been massively reorientated and the population has been in lockdown since 17 March 2020 in France. AIMS: To describe how lockdown has affected the evolution of the weekly rate of myocardial infarctions (non-ST-segment and ST-segment elevation) hospital admissions in Lyon, the second largest city in France. To verify the trend observed, the same analysis was conducted for an identical time window during 2018-2019 and for an unavoidable emergency, i.e. birth. METHODS: Based on the national hospitalisation database [Programme de médicalisation des systèmes d'information (PMSI)], all patients admitted to the main public hospitals for a principal diagnosis of myocardial infarction or birth during the 2nd to the 14th week of 2020 were included. These were compared with the average number of patients admitted for the same diagnosis during the same time window in 2018 and 2019. RESULTS: Before lockdown, the number of admissions for myocardial infarction in 2020 differed from that in 2018-2019 by less than 10%; after the start of lockdown, it decreased by 31% compared to the corresponding time window in 2018-2019. Conversely, the numbers of births remained stable across years and before and after the start of lockdown. CONCLUSION: This study strongly suggests a decrease in the number of admissions for myocardial infarction during lockdown. Although we do not have a long follow-up to determine whether this trend will endure, this is an important warning for the medical community and health authorities.
