RESUMEN
AIMS: Vericiguat is a soluble guanylate cyclase stimulator and improves survival in patients with heart failure (HF) with reduced ejection fraction (HFrEF) and an increased risk of decompensation. As real-world data on how many patients could be eligible for vericiguat therapy derive from outdated registries, we aimed to assess eligibility in a prospective cohort of patients with HF. METHODS AND RESULTS: Data from consecutive HF patients undergoing an elective ambulatory visit at five university hospitals from 3 July to 28 July 2023 were collected. Independent investigators assessed which patients (i) met the eligibility criteria of the VICTORIA trial, (ii) complied with HF guideline recommendations, (iii) met regulatory agency criteria, or (iv) met criteria for refundability according to the Italian regulatory agency. Patients (n = 346, 72% men, median age 69 years) had HFrEF in 57% of cases, left ventricular ejection fraction < 45% in 68%, and New York Heart Association class II-IV symptoms in 76%. Patients meeting the eligibility criteria of the VICTORIA trial or European and American HF Guideline recommendations were 9% and 13%, respectively. Patients meeting Food and Drug Administration (FDA) or European Medicines Agency (EMA) label criteria were 19% and 17%, respectively. Drug costs would be covered by the Italian National Health System in 10% of patients [if a sodium-glucose cotransporter-2 inhibitor (SGLT2i) is not mandatory] or in 8% (if an SGLT2i is requested). CONCLUSIONS: In a real-world study, 9% of patients met the eligibility criteria of the VICTORIA trial, but up to 13% complied with guideline recommendations and up to 19% met FDA or EMA criteria. In Italy, drug costs would be covered by up to 10% of patients.

Bifurcation involvement close to or within the occluded segment poses increasing difficulties for chronic total occlusion (CTO)-percutaneous coronary intervention (PCI). However, this variable is not considered in the angiography-based CTO scoring systems nor has been extensively investigated in large multicenter series. Accordingly, we analyzed a CTO-PCI registry involving 92 European centers to explore the incidence, angiographic and procedural characteristics, and outcomes specific to CTO-PCIs with bifurcation involvement. A total of 3,948 procedures performed between January and November 2023 were examined (33% with bifurcation involvement). Among bifurcation lesions, 38% and 37% were located within 5 mm of the proximal and distal cap, respectively, 16% within the CTO body, and in 9% of cases proximal and distal bifurcations coexisted. When compared with lesions without bifurcation involvement, CTO bifurcation lesions had higher complexity (J-CTO 2.33 ± 1.21 vs 2.11 ± 1.27, p <0.001) and were associated with higher use of additional devices (dual-lumen microcatheter in 27.6% vs 8.4%, p <0.001, and intravascular ultrasound in 32.2% vs 21.7%, p <0.001). Radiation dose (1,544 [836 to 2,819] vs 1,298.5 [699.1 to 2,386.6] mGy, p <0.001) and contrast volume (230 [160 to 300] vs 190 [130 to 250] ml, p <0.001) were also higher. Technical success was similar (91.5% with bifurcation involvement vs 90.4% without bifurcation involvement, p = 0.271). However, the bifurcation lesions within the CTO segment (intralesion) were associated with lower technical success than the other bifurcation-location subgroups (83.7% vs 93.3% proximal, 93.4% distal, and 89.0% proximal and distal, p <0.001). On multivariable analysis, the presence of an intralesion bifurcation was independently associated with technical failure (odds ratio 2.04, 95% confidence interval 1.24 to 3.35, p = 0.005). In conclusion, bifurcations are present in approximately one-third of CTOs who underwent PCI. PCI of CTOs with bifurcation can be achieved with high success rates except for bifurcations within the occluded segment, which were associated with higher technical failure.

(1) Background: This single-center retrospective study aimed to evaluate whether sodium-glucose cotransporter-2 inhibitors (SGLT2-i) therapy may have a nephroprotective effect to prevent contrast-induced acute kidney injury (CI-AKI) in patients with heart failure (HF) undergoing iodinated contrast medium (ICM) invasive procedures. (2) Methods: The population was stratified into SGLT2-i users and SGLT2-i non-users according to the chronic treatment with gliflozins. The primary endpoint was CI-AKI incidence during hospitalization. Secondary endpoints were all-cause mortality and the need for continuous renal replacement therapy (CRRT). (3) Results: In total, 86 patients on SGLT2-i and 179 patients not on SGLT2-i were enrolled. The incidence of CI-AKI in the gliflozin group was lower than in the non-user group (9.3 vs. 27.3%, p < 0.001), and these results were confirmed after propensity matching analysis. Multivariable logistic regression showed that only SGLT2-i treatment was an independent preventive factor for CI-AKI (OR: 0.41, 95% CI: 0.16-0.90, p = 0.045). The need for CRRT was reported only in five patients in the non-SGLT2-i-user group compared to zero patients in the gliflozin group (p = 0.05). (4) Conclusions: SGLT2-i therapy was associated with a lower risk of CI-AKI in patients with HF undergoing ICM invasive procedures.
RESUMEN
BACKGROUND: Whether, and to what extent, frailty and other geriatric domains are linked to health status in patients with transthyretin cardiac amyloidosis (ATTR-CA) is unknown. AIMS: To determine the association of frailty with health status [defined by the Kansas City Cardiomyopathy Questionnaire (KCCQ)] in patients with ATTR-CA. METHODS: Consecutive ATTR-CA patients undergoing cardiovascular assessment at a tertiary care clinic from September 2021 to September 2023 were invited to participate. KCCQ, frailty and social environment were recorded. Frailty was assessed using the modified Frailty Index (mFI), mapping 11 variables from the Canadian Study of Health and Aging (frailty ≥0.36). RESULTS: Of 168 screened ATTR-CA patients, 138 [83% men, median age of 79 (75-84) years] were enrolled in the study. Median KCCQ was 66 (50-75). wtATTR-CA was the most prevalent form (N = 113, 81.9%). The most frequent cardiac variant was Ile68Leu (17/25 individuals with vATTR-CA). Twenty (14.5%) patients were considered frail, and prevalence of overt disability was 6.5%. At multivariable linear regression analysis, factors associated with worsening KCCQ were age at evaluation, the mFI, NYHA Class, and NAC Score. Gender, ATTR-CA type, phenotype, and LVEF were not associated with health status. DISCUSSION: In older patients diagnosed with ATTR-CA, frailty, symptoms, and disease severity were associated with KCCQ. CONCLUSIONS: Functional status is a determinant of quality of life and health status in older individuals with a main diagnosis of ATTR-CA. Future research may provide more in-depth knowledge on the association of frailty in patients with ATTR-CA with respect to quality of life and prognosis.

Background: Noninvasive imaging methods, either anatomical or functional tests, serve as essential instruments for the appropriate management of patients with established or suspected coronary artery disease (CAD). We sought to evaluate the safety and efficacy of a coronary computed tomography angiography (CCTA) plus stress cardiac magnetic resonance imaging (S-CMR) strategy in patients with chronic coronary syndrome (CCS). Methods: Patients with suspected CCS showing intermediate coronary plaques (stenosis 30-70%) at CCTA underwent S-CMR. Patients with a positive S-CMR were referred to invasive coronary angiography (ICA) plus instantaneous wave-free ratio (iFR), and myocardial revascularization if recommended. All patients received guideline-directed medical therapy (GDMT), including high-dose statins, regardless of myocardial revascularization. The primary endpoint was a composite of death from cardiovascular causes, non-fatal myocardial infarction, and unplanned revascularization. Results: According to the results of CCTA, 62 patients showing intermediate coronary plaques underwent S-CMR, which was positive for a myocardial perfusion deficit in n = 17 (27%) and negative in n = 45 (73%) patients. According to the results of ICA plus iFR, revascularization was performed in 13 patients. No differences in the primary endpoint between the positive and negative S-CMR groups were observed at 1 year (1 [5.9%] vs. 1 [2.2%], p = 0.485) and after a median of 33.4 months (2 [11.8%] vs. 3 [6.7%]; p = 0.605). Conclusions: Our study suggests that a CCTA plus S-CMR strategy is effective for the evaluation of patients with suspicion of CCS at low-intermediate risk, and it may help to refine the selection of patients with intermediate coronary plaques at CCTA needing coronary revascularization.

In this work, the case of a 70-year-old Caucasian woman affected by cryptogenic stroke is reported. After discarding other sources of embolism, a transesophageal echocardiogram was performed, which revealed the presence of a double interatrial septum associated with a left-sided atrial pouch. The persistent interatrial space was identified as the most probable source of thrombus.
RESUMEN
BACKGROUND: Low operator and institutional volume is associated with poorer procedural and long-term clinical outcomes in patients treated with percutaneous coronary interventions (PCI). This study was aimed at evaluating the relationship between operator volume and procedural outcomes of patients treated with PCI for chronic total occlusion (CTO). METHODS: Data were obtained from the national registry of percutaneous coronary interventions (ORPKI) collected from January 2014 to December 2020. The primary endpoint was a procedural success, defined as restoration of thrombolysis in myocardial infarction (TIMI) II/III flow without in-hospital cardiac death and myocardial infarction, whereas secondary endpoints included periprocedural complications. RESULTS: Data of 14,899 CTO-PCIs were analyzed. The global procedural success was 66.1%. There was a direct relationship between the annual volume of CTO-PCIs per operator and the procedural success (OR: 1.006 [95% CI: 1.003-1.009]; P<0.001). The nonlinear relationships of annualized CTO-PCI volume per operator and adjusted outcome rates revealed that operators performing 40 CTO cases per year had the best procedural outcomes in terms of technical success (TIMI flow II/III after PCI), coronary artery perforation rate and any periprocedural complications rate (P<0.0001). Among the other factors associated with procedural success, the following can be noted: multi-vessel, left main coronary artery disease (as compared to single-vessel disease), the usage of rotablation as well as PCI within bifurcation. CONCLUSIONS: High-volume CTO operators achieve greater procedural success with a lower frequency of periprocedural complications. Higher annual caseload might increase the overall quality of CTO-PCI.

BACKGROUND AND AIMS: There is significant potential to streamline the clinical pathway for patients undergoing transcatheter aortic valve implantation (TAVI). The purpose of this study was to evaluate the effect of implementing BENCHMARK best practices on the efficiency and safety of TAVI in 28 sites in 7 European countries. METHODS: This was a study of patients with severe symptomatic aortic stenosis (AS) undergoing TAVI with balloon-expandable valves before and after implementation of BENCHMARK best practices. Principal objectives were to reduce hospital length of stay (LoS) and duration of intensive care stay. Secondary objective was to document patient safety. RESULTS: Between January 2020 and March 2023, 897 patients were documented prior to and 1491 patients after the implementation of BENCHMARK practices. Patient characteristics were consistent with a known older TAVI population and only minor differences. Mean LoS was reduced from 7.7 ± 7.0 to 5.8 ± 5.6 days (median 6 vs. 4 days; P < .001). Duration of intensive care was reduced from 1.8 to 1.3 days (median 1.1 vs. 0.9 days; P < .001). Adoption of peri-procedure best practices led to increased use of local anaesthesia (96.1% vs. 84.3%; P < .001) and decreased procedure (median 47 vs. 60â min; P < .001) and intervention times (85 vs. 95â min; P < .001). Thirty-day patient safety did not appear to be compromised with no differences in all-cause mortality (0.6% in both groups combined), stroke/transient ischaemic attack (1.4%), life-threatening bleeding (1.3%), stage 2/3 acute kidney injury (0.7%), and valve-related readmission (1.2%). CONCLUSIONS: Broad implementation of BENCHMARK practices contributes to improving efficiency of TAVI pathway reducing LoS and costs without compromising patient safety.

BACKGROUND: Percutaneous coronary interventions (PCI) of chronic total occlusions (CTO) have reached high procedural success rates thanks to dedicated equipment, evolving techniques, and worldwide adoption of state-of-the-art crossing algorithms. AIMS: We report the contemporary results of CTO PCIs performed by a large European community of experienced interventionalists. Furthermore, we investigated the impact of different risk factors for procedural major adverse cardiac and cerebrovascular events (MACCE) and trends of employment of specific devices like dual lumen microcatheters, guiding catheter extensions, intravascular ultrasound and calcium-modifying tools. METHODS: We evaluated data from 8,673 CTO PCIs included in the European Registry of Chronic Total Occlusion (ERCTO) between January 2021 and October 2022. RESULTS: The overall technical success rate was 89.1% and was higher in antegrade as compared with retrograde cases (92.8% vs 79.3%; p<0.001). Compared with antegrade procedures, retrograde procedures had a higher complexity of attempted lesions (Japanese CTO [J-CTO] score: 3.0±1.0 vs 1.9±1.2; p<0.001), a higher procedural and in-hospital MACCE rate (3.1% vs 1.2%; p<0.018) and a higher perforation rate with and without tamponade (1.5% vs 0.4% and 8.3% vs 2.1%, respectively; p<0.001). As compared with mid-volume operators, high-volume operators had a higher technical success rate in antegrade and retrograde procedures (93.4% vs 91.2% and 81.5% vs 69.0%, respectively; p<0.001), and had a lower MACCE rate (1.47% vs 2.41%; p<0.001) despite a higher mean complexity of the attempted lesions (J-CTO score: 2.42±1.28 vs 2.15±1.27; p<0.001). CONCLUSIONS: The adoption of different recanalisation techniques, operator experience and the use of specific devices have contributed to a high procedural success rate despite the high complexity of the lesions documented in the ERCTO.

Chronic total occlusions (CTOs) of coronary arteries can be found in the context of chronic or acute coronary syndromes; sometimes they are an incidental finding in those apparently healthy individuals undergoing imaging for preoperative risk assessment. Recently, the invasive management of CTOs has made impressive progress due to sophisticated preinterventional assessment, including advanced non-invasive imaging, the availability of novel and dedicated tools for CTO percutaneous coronary intervention (PCI), and experienced interventionalists working in specialised centres. Thus, it is crucial that referring physicians who see patients with CTO be aware of recent developments and of the initial evaluation requirements for such patients. Besides a careful history and clinical examination, electrocardiograms, exercise tests, and non-invasive imaging modalities are important for selecting the patients most suitable for CTO PCI, while others may be referred to coronary artery bypass graft or optimal medical therapy only. While CTO PCI improves angina and reduces the use of antianginal drugs in patients with symptoms and proven ischaemia, hibernation and/or wall motion abnormalities at baseline or during stress, the effect of CTO PCI on major cardiovascular events is still controversial. This clinical consensus statement specifically focuses on referring physicians, providing a comprehensive algorithm for the preinterventional evaluation of patients with CTO and the current evidence for the clinical effectiveness of the procedure. The proposed care track has been developed by members and with the support of the European Association of Percutaneous Cardiovascular Interventions (EAPCI), the European Association of Cardiovascular Imaging (EACVI), and the European Society of Cardiology (ESC) Working Group on Cardiovascular Surgery.

Background: Patients with atrial fibrillation (AF) have a five-fold increase in stroke events, and â¼90% of the thrombi develop in the left atrial appendage (LAA). Left atrial appendage occlusion (LAAO) has emerged as a safe and feasible alternative to oral anticoagulation (OAC) for stroke prevention in selected patients with non-valvular AF and contraindications to OAC. Atrial fibrillation is closely associated with mitral disease, and there is a growing interest in combined procedures. More than half of patients undergoing a mitral transcatheter edge-to-edge repair (M-TEER) suffer of AF and many have high or unacceptable bleeding risk. Case summary: We present a case of an 80-year-old woman suffering from paroxysmal AF, right carotid siphon aneurysm, and primary mitral regurgitation, with a high bleeding risk, who underwent a combined intervention of M-TEER and LAAO. Discussion: The combination of these two procedures is a logical step once the access to the left atrium is obtained with a transseptal puncture (TSP) and a transesophageal echocardiography (TEE) is in place to guide both procedures. The turning point in LAAO procedure is a correct TSP allowing coaxial alignment of the sheath with the LAA neck. Steerable delivery sheaths are promising dedicated tools, particularly in challenging anatomy or during combined procedures requiring different TSP positions.
RESUMEN
Background: Intravascular lithotripsy (IVL) for calcified lesion preparation prior to drug-eluting stent placement has high procedural success and safety, especially in women, whereas other atheroablative approaches are associated with increased procedural complications. We sought to investigate long-term sex-based outcomes of IVL-facilitated stenting. Methods: We performed a patient-level pooled analysis of the single-arm Disrupt CAD III and IV studies. Patient baseline, procedural characteristics, and outcomes were examined according to sex at 30 days and 1 year. The primary end point was major adverse cardiac events (a composite of cardiac death, all myocardial infarction, or target vessel revascularization). Target lesion failure was defined as cardiac death, target vessel myocardial infarction, or ischemia-driven target lesion revascularization. Results: A total of 448 patients, 106 (24%) women, were included. Women were older and less likely to be smokers. Women had smaller reference vessel diameters (2.8 mm vs 3.1 mm), shorter lesion length (23.6 mm vs 27.1 mm), and shorter total calcified length (44.4 mm vs 49.3 mm) compared with men. Post-IVL angiographic outcomes and complications were similar between women and men. At 1 year, major adverse cardiac event rates (12.3% vs 13.2%, P = .52) were not different between women and men. There were no differences between women and men (10.4% vs 11.2%; P = .43) in target lesion failure at 1 year. Conclusions: Use of IVL in the treatment of severely calcified lesions is associated with low rates of adverse clinical events and with similar safety and effectiveness in women and men at 1 year.
RESUMEN
Background: Coronary artery calcification increases the procedural complexity of percutaneous coronary intervention and is associated with worse outcomes, especially in women. Intravascular lithotripsy (IVL) has been demonstrated to be safe and effective for vessel preparation in severely calcified stenotic lesions before stent implantation. Sex-based outcomes of IVL-facilitated stenting have not been defined. Methods: We performed a patient-level pooled analysis of the 4 prospective, single-arm Disrupt CAD studies that evaluated the safety and efficacy of IVL-facilitated stenting. Patient baseline and procedural characteristics and clinical outcomes were examined based on sex. The primary safety end point was 30-day major adverse cardiovascular events, defined as the composite of cardiac death, myocardial infarction, or target vessel revascularization. The primary efficacy end point was procedural success, defined as stent delivery with residual in-stent stenosis ≤30% without in-hospital major adverse cardiovascular events. Results: A total of 628 patients were included, of which 144 (22.9%) were women. Women were older (P < .001) and more likely to have hyperlipidemia (P = .03), renal insufficiency (P = .05), and prior myocardial infarction (P = .05). Women had smaller mean reference vessel diameter (2.7 â ± â0.4 âmm vs 3.0 â ± â0.5 âmm, P < .001), shorter lesion length (22.4 â ± â10.3 âmm vs 25.0 â ± â11.7 âmm, P = .01), and less side branch involvement (22.9% vs 32.4%, P = .03). Severe coronary calcification defined by angiography, stent delivery success, lesion predilatation, post-IVL dilatation, and poststent dilatation was similar between groups. There were no significant differences between women and men in the primary safety end point (8.3% vs 7.1%, P = .61; adjusted odds ratio 1.66; 95% confidence interval 0.78, 3.34; P = .17) or the primary efficacy end point (91.7% vs 92.6%, P = .72; adjusted odds ratio 0.58; 95% confidence interval 0.29, 1.24; P = .15). Post-IVL serious angiographic complications (flow-limiting dissection, perforation, abrupt closure, slow flow, no reflow) were similar for women and men (1.6% vs 2.3%, P = .75). Conclusions: Despite more comorbidities and smaller vessel size, IVL-facilitated stenting of severely calcified lesions achieves similar safety and efficacy in women and men.
