Off-Label Use of Balloon-Expandable Transcatheter Valves to Treat Pure Aortic Regurgitation.

Transcatheter aortic valve implantation (TAVI) in native pure aortic regurgitation (AR) with off-label use of balloon-expandable valves (BEV) has been reported. However, there are scant data regarding optimal oversizing and its safety, and our study assessed BEV oversizing and outcomes of TAVI. Thirteen consecutive tricuspid aortic valve patients who underwent transfemoral TAVIs for pure AR with Sapien BEV at our center between 2019 and 2023 (69.2% males, mean age 80.8 years, Society of Thoracic Surgeons 4.0%) were divided into small annulus (SA) group (≤618 mm2) where ≥20% oversizing is achievable based on published data on BEV overexpansion, and larger annulus (LA) group (>618 mm2). Overexpansion and actual oversizing were measured on postprocedural computed tomography scan. Technical success was 92.3% with 1 valve embolization in the LA group. The postprocedural computed tomography showed a mean 28.3% oversizing, significantly higher in SA (31.2%) than in LA group (19.4%), p = 0.0092. Oversizing ≥20% was achieved in 100% SA versus 33.3% LA patients (p = 0.046). In conclusion, TAVI in pure AR with oversized Sapien BEV showed good procedural and short-term outcomes when ≥20% oversizing was predictably achievable.

[ANMCO/SIC Consensus statement on pulmonary arterial hypertension]. / Documento di consenso ANMCO/SIC sull'ipertensione arteriosa polmonare.

Pulmonary hypertension (PH) is a frequent pathological condition worldwide, mainly secondary to cardiovascular and respiratory diseases, with a poor prognosis. Pulmonary arterial hypertension (PAH) is a rare form that affects the arterial pulmonary vasculature. PH and PAH are characterized by non-specific symptoms and a progressive increase of pulmonary vascular resistance that results in progressive, sometimes irreversible, right ventricular dysfunction. In recent years, a growing medical and social commitment on this disease allowed more accurate diagnosis in shorter times. However, the gap between guidelines and clinical practice remains a challenge for all medical doctors involved in the disease management. Considering the needs to share and describe diagnostic and therapeutic pathways, to measure the results obtained and to address the economical and organizational problems of this disease, all involved figures should collaborate to improve its prognostic impact and health expenses. In this consensus document, the PH experts of the Italian Association of Hospital Cardiologists (ANMCO) together with those of the Italian Society of Cardiology (SIC), address 1) definition, classification and unmet needs of PH and PAH; 2) classification and characteristics of centers involved in the diagnosis and treatment of the disease; 3) proposal of organization of a diagnostic-therapeutic pathway, based on robust and recent scientific evidence.

Comparison of cardiac magnetic resonance imaging, functional and haemodynamic variables in pulmonary arterial hypertension: insights from REPAIR.

Background: Measures that can detect large treatment effects are important for monitoring therapeutic effectiveness. The 2022 European Society of Cardiology/European Respiratory Society guidelines highlight the importance of imaging in monitoring disease status and treatment response in pulmonary arterial hypertension (PAH). Are the standardised treatment effect sizes (STES) of cardiac magnetic resonance imaging (cMRI) comparable with functional and haemodynamic variables? Methods: REPAIR (ClinicalTrials.gov: NCT02310672) was a prospective, multicentre, single-arm, open-label, 52-week phase 4 study evaluating the effect of macitentan 10 mg, with or without a phosphodiesterase 5 inhibitor (PDE5i), on right ventricular (RV) remodelling, cardiac function and cardiopulmonary haemodynamics. Both cMRI and functional assessments were performed at screening and at weeks 26 and 52; haemodynamic measurements were conducted at screening and week 26. In this post hoc analysis, STES were estimated using the parametric Cohen's d and non-parametric Cliff's delta tests. Results: At week 26, large STES (Cohen's d) were observed for 10 of the 20 cMRI variables assessed, including the prognostic measures of RV and left ventricular stroke volume and RV ejection fraction and the haemodynamic trial end-point, pulmonary vascular resistance; medium STES were observed for 6-min walk distance (6MWD). The STES were consistent in treatment-naïve patients and those escalating therapy and maintained at week 52. Similar results were obtained using the non-parametric Cliff's delta method. Conclusions: The treatment effect of macitentan, alone or in combination with a PDE5i, was comparable for several cMRI and haemodynamic variables with prognostic value in PAH, and greater than that of 6MWD in patients with PAH, highlighting the emerging relevance of cMRI in PAH.

Characterization and natural history of different phenotypes in hereditary transthyretin amyloidosis: 40-year experience at a single Italian referral centre.

AIMS: Hereditary transthyretin amyloidosis (ATTRv) is one of the leading aetiologies of systemic amyloidosis with more than 135 mutations described and a broad spectrum of clinical manifestations. We aimed to provide a systematic description of a population of individuals carrying pathogenic mutations of transthyretin (TTR) gene and to investigate the major clinical events during follow-up. METHODS AND RESULTS: This was an observational, retrospective, cohort study including consecutive patients with mutations of TTR gene, admitted to a tertiary referral centre in Bologna, Italy, between 1984 and 2022. Three hundred twenty-five patients were included: 106 asymptomatic carriers, 49 cardiac phenotype, 49 neurological phenotype, and 121 mixed phenotype. Twenty-two different mutations were found, with Ile68Leu (41.8%), Val30Met (19%), and Glu89Gln (10%) being the most common. After a median follow-up of 51 months, 111 patients (38.3%) died and 9 (11.5%) of the 78 asymptomatic carriers developed ATTRv. Carriers had a prognosis comparable with healthy population, while no significant differences were seen among the three phenotypes adjusted by age. Age at diagnosis, New York Heart Association class III, left ventricular ejection fraction, modified polyneuropathy disability score IV, and disease-modifying therapy were independently associated with survival. CONCLUSION: This study offers a wide and comprehensive overview of ATTRv from the point of view of a tertiary referral centre in Italy. Three main phenotypes can be identified (cardiac, neurological, and mixed) with specific clinical and instrumental features. Family screening programmes are essential to identify paucisymptomatic affected patients or unaffected carriers of the mutation, to be followed through the years. Lastly, disease-modifying therapy represents an evolving cornerstone of the management of ATTRv, with a great impact on mortality.

A total of 325 consecutive patients harbouring a pathogenic mutation in the TTR gene, admitted to a tertiary referral centre in Bologna, Italy, between 1984 and 2022, were included in the study.These patients exhibited significant clinical diversity: 106 were asymptomatic carriers, 49 presented with a cardiac phenotype, 49 had a neurological phenotype, and 121 had a mixed phenotype.Asymptomatic carriers demonstrated a prognosis comparable with healthy population, but some of them may develop signs and symptoms of the disease during follow-up.Survival curves adjusted by age are similar among the three phenotypes.Age at diagnosis, New York Heart Association class, modified polyneuropathy disability score, left ventricular ejection fraction, and disease-modifying therapy were identified as independent factors associated with prognosis.

Effect of Macitentan in Pulmonary Arterial Hypertension and the Relationship Between Echocardiography and cMRI Variables: REPAIR Echocardiography Sub-study Results.

INTRODUCTION: The aim of this sub-study was to evaluate the relationship between echocardiography (echo) and cardiac magnetic resonance imaging (cMRI) variables and to utilize echo to assess the effect of macitentan on right ventricle (RV) structure and function. METHODS: REPAIR (NCT02310672) was a prospective, multicenter, single-arm, open-label, 52-week, phase 4 study in pulmonary arterial hypertension (PAH) patients, which investigated the effect of macitentan 10 mg as monotherapy, or in combination with a phosphodiesterase 5 inhibitor, on RV structure, function, and hemodynamics using cMRI and right heart catheterization. In this sub-study, patients were also assessed by echo at screening and at weeks 26 and/or 52. Post hoc correlation analyses between echo and cMRI variables were performed using Pearson's correlation coefficient, Spearman's correlation coefficient, and Bland-Altman analyses. RESULTS: The Echo sub-study included 45 patients. Improvements in echo-assessed RV stroke volume (RVSV), left ventricular SV (LVSV), LV end-diastolic volume (LVEDV), RV fractional area change (RVFAC), tricuspid annular plane systolic excursion (TAPSE), and in 2D global longitudinal RV strain (2D GLRVS) were observed at weeks 26 and 52 compared to baseline. There was a strong correlation between echo (LVSV, 2D GLRVS, and LVEDV) and cMRI variables, with a moderate correlation for RVSV. Bland-Altman analyses showed a good agreement for LVSV measured by echo versus cMRI, whereas an overestimation in echo-assessed RVSV was observed compared to cMRI (bias of - 15 mL). Hemodynamic and functional variables, as well as safety, were comparable between the Echo sub-study and REPAIR. CONCLUSIONS: A good relationship between relevant echo and cMRI parameters was shown. Improvements in RV structure and function with macitentan treatment was observed by echo, consistent with results observed by cMRI in the primary analysis of the REPAIR study. Echo is a valuable complementary method to cMRI, with the potential to non-invasively monitor treatment response at follow-up. TRIAL REGISTRATION NUMBER: REPAIR NCT02310672.

Prognostic Role of Early Cardiac Magnetic Resonance in Myocardial Infarction With Nonobstructive Coronary Arteries.

BACKGROUND: Cardiac magnetic resonance (CMR) plays a pivotal diagnostic role in myocardial infarction with nonobstructive coronary arteries (MINOCA). To date, a prognostic stratification of these patients is still lacking. OBJECTIVES: This study aims to assess the prognostic role of CMR in MINOCA. METHODS: The authors assessed 437 MINOCA from January 2017 to October 2021. They excluded acute myocarditis, takotsubo syndromes, cardiomyopathies, and other nonischemic etiologies. Patients were classified into 3 subgroups according to the CMR phenotype: 1) presence of late gadolinium enhancement (LGE) and abnormal mapping (M) values (LGE+/M+); 2) regional ischemic injury with abnormal mapping and no LGE (LGE-/M+); and 3) nonpathological CMRs (LGE-/M-). The primary outcome was the presence of major adverse cardiovascular events (MACE). The mean follow-up was 33.7 ± 12.0 months and CMR was performed on average at 4.8 ± 1.5 days from the acute presentation. RESULTS: The final cohort included 198 MINOCA; 116 (58.6%) comprised the LGE+/M+ group. During follow-up, MACE occurred significantly more frequently in MINOCA LGE+/M+ than in the LGE+/M- and normal-CMR (LGE-/M-) subgroups (20.7% vs 6.7% and 2.7%; P = 0.006). The extension of myocardial damage at CMR was significantly greater in patients who developed MACE. In multivariable Cox regression, %LGE was an independent predictor of MACE (HR: 1.123 [95% CI: 1.064-1.185]; P < 0.001) together with T2 mapping values (HR: 1.190 [95% CI: 1.145-1.237]; P = 0.001). CONCLUSIONS: In MINOCA with early CMR execution, the %LGE and abnormal T2 mapping values were identified as independent predictors of adverse cardiac events at ∼3.0 years of follow-up. These parameters can be considered as high-risk markers in MINOCA.

Comparison of different treatment strategies in patients with chronic thromboembolic pulmonary hypertension: a single centre real-world experience.

BACKGROUND: Pulmonary endarterectomy (PEA) has been the most effective therapy for chronic thromboembolic pulmonary hypertension (CTEPH). However, there is a substantial proportion of patients deemed not operable in whom other treatment strategies are available: medical therapy and balloon pulmonary angioplasty (BPA). We aimed to compare different CTEPH treatment strategies effect in a real-world setting. METHODS: All patients with CTEPH referred to our centre were included. We compare the short-term clinical, functional, exercise and haemodynamic effect of medical therapy (irrespective of subsequent treatment strategies), PEA and BPA (irrespective of previous/subsequent treatment strategies); we also describe the long-term outcome of the different patient groups. RESULTS: We included 467 patients (39% were treated only with medical therapy, 43% underwent PEA, 13% underwent BPA and 5% were not treated with any therapy). Patients treated only with medical therapy were the oldest; compared to patients undergoing PEA, they had a lower exercise capacity, a higher risk profile and gained a lower haemodynamic, functional and survival benefit from the treatment. Patients undergoing BPA had a lower haemodynamic improvement but a comparable functional, exercise and risk improvement and a similar survival compared to patients undergoing PEA; their survival is anyway better than patients undergoing only medical treatment. Untreated historical control patients had the worst survival. CONCLUSIONS: We confirm the superiority of PEA compared to any alternative treatment in CTEPH patients and we observe that BPA, in patients deemed not operable or with persistent/recurrent PH after PEA, leads to a better outcome than medical therapy alone.

Predictors and outcomes of pacemaker implantation in patients with cardiac amyloidosis.

OBJECTIVE: We sought to investigate prevalence, incidence and prognostic implications of permanent pacemaker (PPM) implantation in patients with cardiac amyloidosis (CA), thereby identifying the predictors of time to PPM implantation. METHODS: Seven hundred eighty-seven patients with CA (602 men, median age 74 years, 571 transthyretin amyloidosis (ATTR), 216 light-chain amyloidosis (AL)) evaluated at two European referral centres were retrospectively included. Clinical, laboratory and instrumental data were analysed. The associations between PPM implantation and mortality, heart failure (HF) or a composite endpoint of mortality, cardiac transplantation and HF were analysed. RESULTS: 81 (10.3%) patients had a PPM before initial evaluation. Over a median follow-up time of 21.7 months (IQR 9.6-45.2), 81 (10.3%) additional patients (18 with AL (22.2%) and 63 with ATTR (77.8%)) underwent PPM implantation with a median time to implantation of 15.6 months (IQR 4.2-40), complete atrioventricular block was the most common indication (49.4%). Independent predictors of PPM implantation were QRS duration (HR 1.03, 95% CI 1.02 to 1.03, p<0.001) and interventricular septum (IVS) thickness (HR 1.1, 95% CI 1.03 to 1.17, p=0.003). The model to estimate the probability of PPM at 12 months and containing both factors showed a C-statistic of 0.71 and a calibration of slope of 0.98. CONCLUSIONS: Conduction system disease requiring PPM is a common complication in CA that affects up to 20.6% of patients. QRS duration and IVS thickness are independently associated with PPM implantation. A PPM implantation at 12 months model was devised and validated to identify patients with CA at higher risk of requiring a PPM and who require closer follow-up.

Impact of SGLT2-inhibitors on contrast-induced acute kidney injury in diabetic patients with acute myocardial infarction with and without chronic kidney disease: Insight from SGLT2-I AMI PROTECT registry.

AIMS: To analyze the association between chronic SGLT2-I treatment and development of contrast-induced acute kidney injury (CI-AKI) in diabetic patients with acute myocardial infarction (AMI) undergoing PCI. METHODS: Multicenter international registry of consecutive patients with type 2 diabetes mellitus (T2DM) and AMI undergoing PCI between 2018 and 2021. The study population was stratified by the presence of chronic kidney disease (CKD) and anti-diabetic therapy at admission (SGLT2-I versus non-SGLT2-I users). RESULTS: The study population consisted of 646 patients: 111 SGLT2-I users [28 (25.2%) with CKD] and 535 non-SGLT2-I users [221 (41.3%) with CKD]. The median age was 70 [61-79] years. SGLT2-I users exhibited significantly lower creatinine values at 72 h after PCI, both in the non-CKD and CKD stratum. The overall rate of CI-AKI was 76 (11.8%), significantly lower in SGLT2-I users compared to non-SGLT2-I patients (5.4% vs 13.1%, p = 0.022). This finding was also confirmed in patients without CKD (p = 0.040). In the CKD cohort, SGLT2-I users maintained significantly lower creatinine values at discharge. The use of SGLT2-I was an independent predictor of reduced rate of CI-AKI (OR 0.356; 95%CI 0.134-0.943, p = 0.038). CONCLUSION: In T2DM patients with AMI, the use of SGLT2-I was associated with a lower risk of CI-AKI, mostly in patients without CKD.

Sex- and age-related differences in outcomes of patients with acute myocardial infarction: MINOCA vs. MIOCA.

AIMS: The aim of the study is to evaluate the impact of sex on acute myocardial infarction (AMI) patients' clinical presentation and outcomes, comparing those with non-obstructive and obstructive coronary arteries (MINOCA vs. MIOCA). METHODS AND RESULTS: We enrolled 2455 patients with AMI undergoing coronary angiography from January 2017 to September 2021. Patients were divided according to the type of AMI and sex: male (n = 1593) and female (n = 607) in MIOCA and male (n = 87) and female (n = 168) in MINOCA. Each cohort was further stratified based on age (≤/> 70 years). The primary endpoint (MAE) was a composite of all-cause death, recurrent AMI, and hospitalization for heart failure (HF) at follow-up. Secondary outcomes included all-cause and cardiovascular death, recurrent AMI, HF re-hospitalization, and stroke. MINOCA patients were more likely to be females compared with MIOCA ones (P < 0.001). The median follow-up was 28 (15-41) months. The unadjusted incidence of MAE was significantly higher in females compared with males, both in MINOCA [45 (26.8%) vs. 12 (13.8%); P = 0.018] and MIOCA cohorts [203 (33.4%) vs. 428 (26.9%); P = 0.002]. Age was an independent predictor of MAE in both cohorts. Among MINOCA patients, females ≤70 years old had a higher incidence of MAE [18 (23.7%) vs. 4 (5.9%); P = 0.003] compared with male peers, mainly driven by a higher rate of re-hospitalization for HF (P = 0.045) and recurrence of AMI (P = 0.006). Only in this sub-group of MINOCA patients, female sex was an independent predictor of MAE (hazard ratio = 3.09; 95% confidence interval: 1.02-9.59; P = 0.040). MINOCA females ≤70 years old had worse outcomes than MIOCA female peers. CONCLUSION: MINOCA females ≤70 years old had a significantly higher incidence of MAE, compared with males and MIOCA female peers, likely due to the different pathophysiology of the ischaemic event. TRIAL REGISTRATION: Data were part of the ongoing observational study 'AMIPE: Acute Myocardial Infarction, Prognostic and Therapeutic Evaluation' (ClinicalTrials.gov Identifier: NCT03883711).

Predictors of bail-out stenting in patients with small vessel disease treated with drug-coated balloon percutaneous coronary intervention.

BACKGROUND: Drug-coated balloons (DCBs) have shown comparable results with drug-eluting stents in small vessel disease (SVD) percutaneous coronary intervention (PCI) in terms of target vessel revascularization and a reduced incidence of myocardial infarction. However, the relatively high rate of bail-out stenting (BOS) still represents a major drawback of DCB PCI. AIMS: The aim of the study was to investigate the clinical, anatomic, and procedural features predictive of BOS after DCB PCI in SVD. METHODS: We included all consecutive patients undergoing PCI at our institution between January 2020 and May 2022 who were treated with DCB PCI of a de novo lesion in a coronary vessel with a reference vessel diameter (RVD) between 2.0 and 2.5 mm. Angiographic success was defined as a residual stenosis <30% without flow-limiting dissection. Patients who did not meet these criteria underwent BOS. RESULTS: A total of 168 consecutive patients and 216 coronary stenoses were included. The rate of bail-out stent was 13.9%. On multivariate analysis, DCB/RVD ratio (odds ratio [OR]: 4.39, 95% confidence interval [CI]: 1.71-11.29, p < 0.01), vessel tortuosity (OR: 7.00, 95% CI: 1.66-29.62, p < 0.01), distal vessel disease (OR: 5.66, 95% CI: 2.02-15.83, p < 0.01), and high complexity (Grade C of ACC/AHA classification) coronary stenoses (OR: 6.31, 95% CI: 1.53-26.04, p = 0.01) were independent predictors of BOS. CONCLUSIONS: BOS is not an infrequent occurrence in DCB PCI of small vessels and is correlated with vessel tortuosity, distal diffuse vessel disease, higher lesion complexity, and balloon diameter oversizing.

Pulmonary Arterial Hypertension Associated with Portal Hypertension and HIV Infection: Comparative Characteristics and Prognostic Predictors.

BACKGROUND: Pulmonary arterial hypertension (PAH) may complicate both portal hypertension (Po-PAH) and HIV infection (HIV-PAH). These two conditions, however, frequently coexist in the same patient (HIV/Po-PAH). We evaluated clinical, functional, hemodynamic characteristics and prognostic parameters of these three groups of patients. METHODS: We included patients with Po-PAH, HIV-PAH and HIV/Po-PAH referred to a single center. We compared clinical, functional and hemodynamic parameters, severity of liver disease [Child-Turcotte-Pugh (CTP) and Model for End-stage Liver Disease-Na (MELD-Na) scores], CD4 count and highly active antiretroviral therapy (HAART) administration. Prognostic variables were identified through Cox-regression analysis. RESULTS: Patients with Po-PAH (n = 128) were the oldest, patients with HIV-PAH (n = 41) had the worst hemodynamic profile and patients with HIV/Po-PAH (n = 35) had the best exercise capacity. Independent predictors of mortality were age and CTP score for Po-PAH, HAART administration for HIV-PAH, MELD-Na score and hepatic venous-portal gradient for HIV/Po-PAH. CONCLUSIONS: Patients with HIV/Po-PAH are younger and have a better exercise capacity than patients with Po-PAH, have a better exercise capacity and hemodynamic profile compared to patients with HIV-PAH, and their prognosis seems to be related to the hepatic disease rather than to HIV infection. The prognosis of patients with Po-PAH and HIV-PAH seems to be related to the underlying disease.

Progress in the treatment of acute pulmonary embolism and chronic thrombo-embolic pulmonary hypertension/disease.

The combination of an initial clinical approach aimed at evaluating the early risk of mortality with subsequent diagnostic and therapeutic approaches articulated on the overall patient's profile is recommended in acute pulmonary embolism (PE). The presence of pulmonary hypertension associated with the persistence of chronic vascular obstructions in the pulmonary arteries after one or more acute thrombo-embolic events identifies a condition defined as chronic thrombo-embolic pulmonary hypertension (CTEPH). The evolution of technology and knowledge in the field of imaging has allowed us to qualify the computed tomography angiography of the pulmonary arteries as the gold standard for the diagnostic confirmation of both acute PE and CTEPH. In both these conditions, the first therapeutic step is the immediate initiation of anticoagulant therapy. In acute high-risk PE, in addition to anticoagulant therapy, thrombolytic therapy is recommended; in the event of contraindications to thrombolysis, surgical embolectomy or percutaneous catheter-directed treatment represents viable treatment options. In CTEPH, the combination of data collected from cardiac catheterization, computed tomography angiography, and conventional angiography of pulmonary arteries allows a team of experts to identify candidates for pulmonary endarterectomy surgery. Inoperable patients should be considered for percutaneous balloon angioplasty of the pulmonary arteries which can improve patients' symptoms, quality of life, and prognosis.

Sex-Related Disparities in Cardiac Masses: Clinical Features and Outcomes.

BACKGROUND: Cardiac masses (CM) represent a heterogeneous clinical scenario, and sex-related differences of these patients remain to be established. PURPOSE: To evaluate sex-related disparities in CMs regarding clinical presentation and outcomes. MATERIAL AND METHODS: The study cohort included 321 consecutive patients with CM enrolled in our Centre between 2004 and 2022. A definitive diagnosis was achieved by histological examination or, in the case of cardiac thrombi, with radiological evidence of thrombus resolution after anticoagulant treatment. All-cause mortality at follow-up was evaluated. Multivariable regression analysis assessed the potential prognostic disparities between men and women. RESULTS: Out of 321 patients with CM, 172 (54%) were female. Women were more frequently younger (p = 0.02) than men. Regarding CM histotypes, females were affected by benign masses more frequently (with cardiac myxoma above all), while metastatic tumours were more common in men (p < 0.001). At presentation, peripheral embolism occurred predominantly in women (p = 0.03). Echocardiographic features such as greater dimension, irregular margin, infiltration, sessile mass and immobility were far more common in men. Despite a better overall survival in women, no sex-related differences were observed in the prognosis of benign or malignant masses. In fact, in multivariate analyses, sex was not independently associated with all-cause death. Conversely, age, smoking habit, malignant tumours and peripheral embolism were independent predictors of mortality. CONCLUSIONS: In a large cohort of cardiac masses, a significant sex-related difference in histotype prevalence was found: Benign CMs affected female patients more frequently, while malignant tumours affected predominantly men. Despite better overall survival in women, sex did not influence prognosis in benign and malignant masses.

Early detection of cancer therapy cardiotoxicity by radionuclide angiography: An update.

Cancer therapy-induced cardiotoxicity is an emerging clinical and healthcare issue. Myocardial dysfunction and heart failure are mostly responsible for increased cardiovascular mortality in cancer disease survivors. Several imaging surveillance techniques have been proposed for early diagnosis of cancer therapy-induced cardiac dysfunction. Our aim was to provide an update of radionuclide angiography applications in this field. Radionuclide angiography is widely used to assess left ventricular ejection fraction (LVEF) throughout cancer treatment, especially in patients with limited acoustic window. Additional prognostic data may be provided by phase analysis and diastolic function evaluation. Low LVEF and high approximate entropy at baseline seem to be predictors for cancer therapy-induced cardiac dysfunction. A decrease in peak filling rate and/or an increase in time to peak filling rate may be observed in patients undergoing anthracycline and/or trastuzumab administration. Diastolic function impairment may precede or not LVEF decrease. In conclusion, recent studies have provided novel insights into the possible role of radionuclide angiography in the early detection of cancer therapy cardiotoxicity. While interpreting the results of a radionuclide angiography examination, an integrated approach combining the evaluation of LVEF, LV diastolic function, and phase analysis may be useful to improve risk stratification of cancer patients treated with cardiotoxic agents.

Screening approaches to cardiac amyloidosis in different clinical settings: Current practice and future perspectives.

Cardiac amyloidosis is a serious and progressive infiltrative disease caused by the deposition of amyloid fibrils in the heart. In the last years, a significant increase in the diagnosis rate has been observed owing to a greater awareness of its broad clinical presentation. Cardiac amyloidosis is frequently associated to specific clinical and instrumental features, so called "red flags", and it appears to occur more commonly in particular clinical settings such as multidistrict orthopedic conditions, aortic valve stenosis, heart failure with preserved or mildly reduced ejection fraction, arrhythmias, plasma cell disorders. Multimodality approach and new developed techniques such PET fluorine tracers or artificial intelligence may contribute to strike up extensive screening programs for an early recognition of the disease.

European Society of Cardiology quality indicators for the care and outcomes of adults with pulmonary arterial hypertension. Developed in collaboration with the Heart Failure Association of the European Society of Cardiology.

AIMS: To develop a suite of quality indicators (QIs) for the evaluation of the care and outcomes for adults with pulmonary arterial hypertension (PAH). METHODS AND RESULTS: We followed the European Society of Cardiology (ESC) methodology for the development of QIs. This included (i) the identification of key domains of care for the management of PAH, (ii) the proposal of candidate QIs following systematic review of the literature, and (iii) the selection of a set of QIs using a modified Delphi method. The process was undertaken in parallel with the writing of the 2022 ESC/European Respiratory Society (ERS) guidelines for the diagnosis and treatment of pulmonary hypertension and involved the Task Force chairs, experts in PAH, Heart Failure Association (HFA) members and patient representatives. We identified five domains of care for patients with PAH: structural framework, diagnosis and risk stratification, initial treatment, follow-up, and outcomes. In total, 23 main and one secondary QIs for PAH were selected. CONCLUSION: This document presents the ESC QIs for PAH, describes their development process and offers scientific rationale for their selection. The indicators may be used to quantify and improve adherence to guideline-recommended clinical practice and improve patient outcomes.

Coronary ectasia in different scenarios, primarily in myocardial infarction with nonobstructive coronary artery disease.

AIMS: Several causes have been reported for coronary artery ectasia (CAE), mostly atherosclerosis and tunica media abnormalities. The main aim of the present study was to investigate if CAE extension differs in distinct clinical settings. METHODS: Three hundred and forty-one patients with diagnosis of CAE were identified among 9659 coronary angiographies and divided into four groups according to the patient's admission diagnosis: stable or unstable angina (S-UA), myocardial infarction (MI), aortic disease, aortic valvular disease (AVD). S-UA and MI were subgrouped according to the presence of obstructive coronary artery disease (OCAD). Multivariable logistic regression was used to investigate the relationship between clinical diagnosis and CAE extension as expressed by Markis classification and number of coronary vessels affected by CAE. RESULTS: No significant differences in CAE extension were found among the four groups, in terms of vessels affected by CAE (P = 0.37) or Markis class (P = 0.33). CAE was not related to the extension of OCAD as assessed by the Gensini score, which was higher in MI and S-UA groups (P < 0.01). However, when ischemic patients were sub-divided on the basis of the presence of OCAD, MI without obstructive coronary artery disease (MINOCA) was associated with a higher extension of CAE in terms of Markis class 1 (OR 5.08, 95% CI 1.61-16.04; P < 0.01). CONCLUSION: The extension of CAE is comparable in patients referred to coronary angiography for different clinical scenarios, including S-UA, MI, aortic disease, and AVD; however, patients with MINOCA were associated with a higher extension of CAE.Graphical abstract: Difference in coronary artery ectasia extension in terms of Markis class severity, respectively, stratified by clinical presentation and obstructive coronary artery disease presence, http://links.lww.com/JCM/A519.
