Cardiogenic shock and chronic kidney disease: Dangerous liaisons.

BACKGROUND: Chronic kidney disease (CKD) is one of the leading causes of death worldwide, closely interrelated with cardiovascular diseases, ultimately leading to the failure of both organs - the so-called "cardiorenal syndrome". Despite this burden, data related to cardiogenic shock outcomes in CKD patients are scarce. METHODS: FRENSHOCK (NCT02703038) was a prospective registry involving 772 patients with cardiogenic shock from 49 centres. One-year outcomes (rehospitalization, death, heart transplantation, ventricular assist device) were analysed according to history of CKD at admission and were adjusted on independent predictive factors. RESULTS: CKD was present in 164 of 771 patients (21.3%) with cardiogenic shock; these patients were older (72.7 vs. 63.9years) and had more comorbidities than those without CKD. CKD was associated with a higher rate of all-cause mortality at 1month (36.6% vs. 23.2%; hazard ratio 1.39, 95% confidence interval 1.01-1.9; P=0.04) and 1year (62.8% vs. 40.5%, hazard ratio 1.39, 95% confidence interval 1.09-1.77; P<0.01). Patients with CKD were less likely to be treated with norepinephrine/epinephrine or undergo invasive ventilation or receive mechanical circulatory support, but were more likely to receive renal replacement therapy (RRT). RRT was associated with a higher risk of all-cause death at 1month and 1year regardless of baseline CKD status. CONCLUSIONS: Cardiogenic shock and CKD are frequent "cross-talking" conditions with limited therapeutic options, resulting in higher rates of death at 1month and 1year. RRT is a strong predictor of death, regardless of preexisting CKD. Multidisciplinary teams involving cardiac and kidney physicians are required to provide integrated care for patients with failure of both organs.

Sex disparities in cardiogenic shock: Insights from the FRENSHOCK registry.

BACKGROUND: Cardiogenic shock (CS) is the most severe form of acute heart failure. Discrepancies have been reported between sexes regarding delays, pathways and invasive strategies in CS complicating acute myocardial infarction. However, effect of sex on the prognosis of unselected CS remains controversial. OBJECTIVES: The aim was to analyze the impact of sex on aetiology, management and prognosis of CS. METHODS: The FRENSHOCK registry included all CS admitted in 49 French Intensive Care Units (ICU) and Intensive Cardiac Care Units (ICCU) between April and October 2016. RESULTS: Among the 772 CS patients included, 220 were women (28.5%). Women were older, less smokers, with less history of ischemic cardiac disease (20.5% vs 33.6%) than men. At admission, women presented less cardiac arrest (5.5 vs 12.2%), less mottling (32.5 vs 41.4%) and higher LVEF (30 ± 14 vs 25 ± 13%). Women were more often managed via emergency department while men were directly admitted at ICU/ICCU. Ischemia was the most frequent trigger irrespective of sex (36.4% in women vs 38.2%) but women had less coronary angiogram and PCI (45.9% vs 54% and 24.1 vs 31.3%, respectively). We found no major difference in medication and organ support. Thirty-day mortality (26.4 vs 26.5%), transplant or permanent assist device were similar in both sexes. CONCLUSION: Despite some more favorable parameters in initial presentation and no significant difference in medication and support, women shared similar poor prognosis than men. Further analysis is required to cover the lasting gap in knowledge regarding sex specificities to distinguish between differences and inequalities. NCT02703038.

Optimal Heart Failure Medical Therapy and Mortality in Survivors of Cardiogenic Shock: Insights From the FRENSHOCK Registry.

BACKGROUND: The effects of pharmacological therapy on cardiogenic shock (CS) survivors have not been extensively studied. Thus, this study investigated the association between guideline-directed heart failure (HF) medical therapy (GDMT) and one-year survival rate in patients who are post-CS. METHODS AND RESULTS: FRENSHOCK (French Observatory on the Management of Cardiogenic Shock in 2016) registry was a prospective multicenter observational survey, conducted in metropolitan French intensive care units and intensive cardiac care units. Of 772 patients, 535 patients were enrolled in the present analysis following the exclusion of 217 in-hospital deaths and 20 patients with missing medical records. Patients with triple GDMT (beta-blockers, renin-angiotensin system inhibitors, and mineralocorticoid receptor antagonists) at discharge (n=112) were likely to have lower left ventricular ejection fraction on admission and at discharge compared with those without triple GDMT (n=423) (22% versus 28%, P<0.001 and 29% versus 37%, P<0.001, respectively). In the overall cohort, the one-year mortality rate was 23%. Triple GDMT prescription was significantly associated with a lower one-year all-cause mortality compared with non-triple GDMT (adjusted hazard ratio 0.44 [95% CI, 0.19-0.80]; P=0.007). Similarly, 2:1 propensity score matching and inverse probability treatment weighting based on the propensity score demonstrated a lower incidence of one-year mortality in the triple GDMT group. As the number of HF drugs increased, a stepwise decrease in mortality was observed (log rank; P<0.001). CONCLUSIONS: In survivors of CS, the one-year mortality rate was significantly lower in those with triple GDMT. Therefore, this study suggests that intensive HF therapy should be considered in patients following CS.

Clinical effects of permanent pacemaker implantation after transcatheter aortic valve implantation: Insights from the nationwide FRANCE-TAVI registry.

BACKGROUND: The influence of permanent pacemaker implantation upon outcomes after transcatheter aortic valve implantation (TAVI) remains controversial. AIMS: To evaluate the impact of permanent pacemaker implantation after TAVI on short- and long-term mortality, and on the risk of hospitalization for heart failure. METHODS: Data from the large FRANCE-TAVI registry, linked to the French national health single-payer claims database, were analysed to compare 30-day and long-term mortality rates and hospitalization for heart failure rates among patients with versus without permanent pacemaker implantation after TAVI. Multivariable regressions were performed to adjust for confounders. RESULTS: A total of 36,549 patients (mean age 82.6years; 51.6% female) who underwent TAVI from 2013 to 2019 were included in the present analysis. Among them, 6999 (19.1%) received permanent pacemaker implantation during the index hospitalization, whereas 232 (0.6%) underwent permanent pacemaker implantation between hospital discharge and 30days after TAVI, at a median of 11 (interquartile range: 7-18) days. In-hospital permanent pacemaker implantation was not associated with an increased risk of death between discharge and 30days (adjusted odds ratio: 0.91, 95% confidence interval: 0.64-1.29). At 5years, the incidence of all-cause death was higher among patients with versus without permanent pacemaker implantation within 30days of the procedure (adjusted hazard ratio: 1.13, 95% confidence interval: 1.07-1.19). Permanent pacemaker implantation within 30days of TAVI was also associated with a higher 5-year rate of hospitalization for heart failure (adjusted subhazard ratio: 1.17, 95% confidence interval: 1.11-1.23). CONCLUSIONS: Permanent pacemaker implantation after TAVI is associated with an increased risk of long-term hospitalization for heart failure and all-cause mortality. Further research to mitigate the risk of postprocedural permanent pacemaker implantation is needed as TAVI indications expand to lower-risk patients.

Transcatheter aortic valve implantation impact on left ventricular myocardial damage: long term follow-up.

INTRODUCTION: Aortic stenosis (AS) is causing myocardial damages and replacement is mainly indicated based on symptoms. Non-invasive estimation of myocardial work (MW) provide a less afterload dependent tool that, we sought to look at the impact of transcatheter aortic valve implantation (TAVI) on the myocardium at long-term follow-up and according to current indications. METHODS: We conducted an observational, cross-sectional, single-center study. Patients were selected based on the validated indication for a TAVI. Standardized echocardiographies were repeated. RESULTS: 102 patients were included. Mean age was 85-year-old, 45% were female, 68% get high-blood pressure and 52% had a coronary disease. One fifth was suffering from low-flow low-gradient aortic stenosis. Follow-up was performed at 22 ± 9.5 months after the TAVI. No TAVI-dysfunction was observed. LVEF was stable (62 ± 8%), and global longitudinal strain get improved (-14.0% ± 3.7 vs -16.0% ± 3.6, p-value <0.0001). No improvement of the MW-parameters was noticed (Global Work Index (LV GWI) 2099 ± 692mmHg% vs 2066 ± 706mmHg%, p=0.8, Global Constructive (LV GCW) 2463 ± 736mmHg% vs 2463 ± 676mmHg%, p=0.8). Global Wasted Work increased (214 [149; 357] mmHg% vs 247 [177; 394] mmHg%, p= 0.0008). CONCLUSION: In a population of severe symptomatic AS-patients who had undergone a TAVI, the non-invasive myocardial indices that assess the LV performance at long term follow-up did not improve. These results are questioning the timing of the intervention and the need for a more attention in the pharmacological management of these AS-patients.

Echocardiographic estimation of pulmonary pressure in patients with severe tricuspid regurgitation.

OBJECTIVES: The estimation of systolic pulmonary artery pressure (sPAP) by transthoracic echocardiography (TTE) is challenging in patients with severe tricuspid regurgitation (TR). The study aimed to determine the reliability of the assessment of sPAP by TTE in this population. METHODS: This study was a single-centre analysis of consecutive patients at the University Hospital of Rennes with right heart catheterisation and TTE, performed with a maximum delay of 48 hours. Lin's concordance coefficient (LCC) and Bland-Altman analysis were used to compare the values. RESULTS: After applying the exclusion criteria, 236 patients were included in the analysis (age 71±11.5 years old; male 56%). The two principal indications were TR (34.3%) and mitral regurgitation (32.2%). The correlation between the two procedures was good in the total population (LCC=0.80; 95% limits of agreement (LOA): 0.74, 0.84), but weaker in the 78 patients (33%) with severe TR (LCC=0.67; 95% LOA: 0.49, 0.80), with a propensity to an underestimation by TTE. An elevated right atrial pressure (RAP) was associated with an underestimation by TTE of about 8 mmHg. The presence of a 'V-wave cut-off' sign on continuous-wave Doppler (OR=3.74; 95% CI 1.48, 9.30; p<0.01), found exclusively in patients with severe TR, was an independent predictor of sPAP misestimation by TTE. CONCLUSION: The reliability of the estimation of sPAP in patients with severe TR could be altered by high RAP which cannot be estimated with current thresholds.

Characteristics, management, and mid-term prognosis of older adults with cardiogenic shock admitted to intensive care units: Insights from the FRENSHOCK registry.

BACKGROUND: The incidence of heart failure and cardiogenic shock (CS) in older adults is continually increasing due to population aging. To date, prospective data detailing the specific characteristics, management and outcomes of CS in this population are scarce. METHODS: FRENSHOCK is a prospective registry including 772 CS patients from 49 centers. We studied 1-month and 1-year mortality among patients over 75-year-old, adjusted for independent predictors of 1-month and 1-year mortalities. RESULTS: Out of 772 patients included, 236 (30.6%) were 75 years old or more (mean age 81.9 ± 4.7 years, 63.6% male). Compared to patients <75 years old, older adults had a higher prevalence of comorbidities including hypertension, dyslipidemia, chronic kidney disease, and history of heart disease. Older adults were characterized by a lower blood pressure, as well as higher creatinine and lower haemoglobin levels at presentation. Yet, they were less likely to be treated with norepinephrine, epinephrine, invasive ventilation, and renal replacement therapy. They showed a higher 1-month (aHR: 2.5 [1.86-3.35], p < 0.01) and 1-year mortality (aHR: 2.01 [1.58-2.56], p < 0.01). Analysis of both 1-month and 1-year mortality stratified by age quartiles showed a gradual relationship between aging and mortality in CS patients. CONCLUSION: A third of patient with CS in critical care unit are older than 75 years and their risk of death at one month and one year is more than double compared to the younger ones. Further research is essential to identify best therapeutic strategy in this population. NCT02703038.

Beta Blockers Improve Prognosis When Used Early in Patients with Cardiogenic Shock: An Analysis of the FRENSHOCK Multicenter Prospective Registry.

BACKGROUND: Beta blockers (BBs) are a cornerstone for patients with heart failure (HF) and ventricular dysfunction. However, their use in patients recovering from a cardiogenic shock (CS) remains a bone of contention, especially regarding whether and when to reintroduce this class of drugs. METHODS: FRENSHOCK is a prospective multicenter registry including 772 CS patients from 49 centers. Our aim was to compare outcomes (1-month and 1-year all-cause mortality) between CS patients taking and those not taking BBs in three scenarios: (1) at 24 h after CS; (2) patients who did or did not discontinue BBs within 24 h; and (3) patients who did or did not undergo the early introduction of BBs. RESULTS: Among the 693 CS included, at 24 h after the CS event, 95 patients (13.7%) were taking BB, while 598 (86.3%) were not. Between the groups, there were no differences in terms of major comorbidities or initial CS triggers. Patients receiving BBs at 24 h presented a trend toward reduced all-cause mortality both at 1 month (aHR = 0.61, 95% CI 0.34 to 1.1, p = 0.10) and 1 year, which was, in both cases, not significant. Compared with patients who discontinued BBs at 24 h, patients who did not discontinue BBs showed lower 1-month mortality (aHR = 0.43, 95% CI 0.2 to 0.92, p = 0.03) and a trend to lower 1-year mortality. No reduction in outcomes was observed in patients who underwent an early introduction of BB therapy. CONCLUSIONS: BBs are drugs of first choice in patients with HF and should also be considered early in patients with CS. In contrast, the discontinuation of BB therapy resulted in increased 1-month all-cause mortality and a trend toward increased 1-year all-cause mortality.

Impella for the Management of Ventricular Septal Defect Complicating Acute Myocardial Infarction: A European Multicenter Registry.

Ventricular septal defect (VSD) is a rare but severe complication of myocardial infarction (MI). Temporary mechanical circulatory support (MCS) can be used as a bridge to VSD closure, heart transplantation, or ventricular assist device. We describe the use of Impella device in this context based on a multicenter European retrospective registry (17 centers responded). Twenty-eight post-MI VSD patients were included (Impella device were 2.5 for 1 patient, CP for 20, 5.0 for 5, and unknown for 2). All patients were in cardiogenic shock with multiple organ failure (SAPS II 41 [interquantile range {IQR} = 27-53], lactate 4.0 ± 3.5 mmol/L) and catecholamine support (dobutamine 55% and norepinephrine 96%). Additional temporary MCS was used in 14 patients (50%), mainly extracorporeal life support (ECLS) (n = 9, 32%). Severe bleedings were frequent (50%). In-hospital and 1 year mortalities were 75%. Ventricular septal defect management was surgical for 36% of patients, percutaneous for 21%, and conservative for 43%. Only surgically managed patients survived (70% in-hospital survival). Type and combination of temporary MCS used were not associated with mortality (Impella alone or in combination with intra-aortic balloon pump [IABP] or ECLS, p = 0.84). Impella use in patients with post-MI VSD is feasible but larger prospective registries are necessary to further elucidate potential benefits of left ventricular unloading in this setting.

1-Year Outcomes With Fourth-Generation Mitral Valve Transcatheter Edge-to-Edge Repair From the EXPAND G4 Study.

BACKGROUND: The fourth-generation mitral transcatheter edge-to-edge repair (M-TEER) device introduced an improved clip deployment sequence, independent leaflet grasping, and 2 wider clip sizes to tailor the treatment of patients with mitral regurgitation (MR) for a broad range of anatomies. The 30-day safety and effectiveness of the fourth-generation M-TEER device were previously demonstrated. OBJECTIVES: The aim of this study was to evaluate 1-year outcomes in a contemporary, real-world cohort of subjects treated with the MitraClip G4 system. METHODS: EXPAND G4 is an ongoing prospective, multicenter, international, single-arm study that enrolled subjects with primary and secondary MR. One-year outcomes included MR severity (echocardiographic core laboratory assessed), heart failure hospitalization, all-cause mortality, functional capacity (NYHA functional class), and quality of life (Kansas City Cardiomyopathy Questionnaire). RESULTS: A total of 1,164 subjects underwent M-TEER from 2020 to 2022. At 1 year, there was a durable reduction in MR to mild or less in 92.6% and to none or trace in 44.2% (P < 0.0001 vs baseline). Few subjects had major adverse events through 1 year (<2% for myocardial infarction, surgical reintervention, or single-leaflet device attachment). The 1-year Kaplan-Meier estimates for all-cause mortality and heart failure hospitalization were 12.3% and 16.9%. Significant improvements in functional capacity (NYHA functional class I or II in 82%; P < 0.0001 vs baseline) and quality of life (18.5-point Kansas City Cardiomyopathy Questionnaire overall summary score improvement; P < 0.0001) were observed. CONCLUSIONS: M-TEER with the fourth-generation M-TEER device was safe and effective at 1 year, with durable reductions in MR severity to ≤1+ in more than 90% of patients and concomitant improvements in functional status and quality of life.

One-year outcomes in cardiogenic shock triggered by supraventricular tachycardia: an analysis of the FRENSHOCK multicenter prospective registry.

Background: Cardiogenic shock (CS) is the most severe form of heart failure (HF), resulting in high early and long-term mortality. Characteristics of CS secondary to supraventricular tachycardia (SVT) are poorly reported. Based on a large registry of unselected CS, we aimed to compare 1-year outcomes between SVT-triggered and non-SVT-triggered CS. Methods: FRENSHOCK is a French prospective registry including 772 CS patients from 49 centers. For each patient, the investigator could report 1-3 CS triggers from a pre-established list (ischemic, mechanical complications, ventricular/supraventricular arrhythmia, bradycardia, iatrogenesis, infection, non-compliance, and others). In this study, 1-year outcomes [rehospitalizations, mortality, heart transplantation (HTx), ventricular assist devices (VAD)] were analyzed and adjusted for independent predictive factors. Results: Among 769 CS patients included, 100 were SVT-triggered (13%), of which 65 had SVT as an exclusive trigger (8.5%). SVT-triggered CS patients exhibited a higher proportion of male individuals with a more frequent history of cardiomyopathy or chronic kidney disease and more profound CS (biventricular failure and multiorgan failure). At 1 year, there was no difference in all-cause mortality (43% vs. 45.3%, adjusted HR 0.9 (95% CI 0.59-1.39), p = 0.64), need for HTx or VAD [10% vs. 10%, aOR 0.88 (0.41-1.88), p = 0.74], or rehospitalizations [49.4% vs. 44.4%, aOR 1.24 (0.78-1.98), p = 0.36]. Patients with SVT as an exclusive trigger presented more 1-year rehospitalizations [52.8% vs. 43.3%, aOR 3.74 (1.05-10.5), p = 0.01]. Conclusion: SVT is a frequent trigger of CS alone or in association in more than 10% of miscellaneous CS cases. Although SVT-triggered CS patients were more comorbid with more pre-existing cardiomyopathies and HF incidences, they presented similar rates of mortality, HTx, and VAD at 1 year, arguing for a better overall prognosis.

Cardiogenic Shock in Idiopathic Dilated Cardiomyopathy Patients: Red Flag for Myocardial Decline.

Idiopathic dilated cardiomyopathy (IDCM) is one of the most common forms of nonischemic cardiomyopathy worldwide, possibly leading to cardiogenic shock (CS). Despite this heavy burden, the outcomes of CS in IDCM are poorly reported. Based on a large registry of unselected CS, our aim was to shed light on the 1-year outcomes after CS in patients with and without IDCM. FRENSHOCK was a prospective registry including 772 patients with CS from 49 centers. The 1-year outcomes (rehospitalizations, mortality, heart transplantation [HTx], ventricular assist devices [VAD]) were analyzed and adjusted on independent predictive factors. Within 772 CS included, 78 occurred in IDCM (10.1%). Patients with IDCM had more frequent history of chronic kidney failure and implantable cardioverter-defibrillator implantation. No difference was found in 1-month all-cause mortality between groups (28.2 vs 25.8%for IDCM and others, respectively; adjusted hazard ratio 1.14 [0.73 to 1.77], p = 0.57). Patients without IDCM were more frequently treated with noninvasive ventilation and intra-aortic balloon pump. At 1 year, IDCM led to higher rates of death or cardiovascular rehospitalizations (adjusted odds ratio 4.77 [95% confidence interval 1.13 to 20.1], p = 0.03) and higher rates of HTx or VAD for patients aged <65 years (adjusted odds ratio 2.68 [1.21 to 5.91], p = 0.02). In conclusion, CS in IDCM is a very common scenario and is associated with a higher rate of 1-year death or cardiovascular rehospitalizations and a more frequent recourse to HTx or VAD for patients aged <65 years, encouraging the consideration of it as a red flag for myocardial decline and urging for a closer follow-up and earlier evaluation for advanced heart failure therapies.

Mottling as a prognosis marker in cardiogenic shock.

AIMS: Impact of skin mottling has been poorly studied in patients admitted for cardiogenic shock. This study aimed to address this issue and identify determinants of 30-day and 1-year mortality in a large cardiogenic shock cohort of all etiologies. METHODS AND RESULTS: FRENSHOCK is a prospective multicenter observational registry conducted in French critical care units between April and October, 2016. Among the 772 enrolled patients (mean age 65.7 ± 14.9 years; 71.5% male), 660 had skin mottling assessed at admission (85.5%) with almost 39% of patients in cardiogenic shock presenting mottling. The need for invasive respiratory support was significantly higher in patients with mottling (50.2% vs. 30.1%, p < 0.001) and likewise for the need for renal replacement therapy (19.9% vs. 12.4%, p = 0.09). However, the need for mechanical circulatory support was similar in both groups. Patients with mottling at admission presented a higher length of stay (19 vs. 16 days, p = 0.033), a higher 30-day mortality rate (31% vs. 23.3%, p = 0.031), and also showed significantly higher mortality at 1-year (54% vs. 42%, p = 0.003). The subgroup of patients in whom mottling appeared during the first 24 h after admission had the worst prognosis at 30 days. CONCLUSION: Skin mottling at admission in patients with cardiogenic shock was statistically associated with prolonged length of stay and poor outcomes. As a perfusion-targeted resuscitation parameter, mottling is a simple, clinical-based approach and may thus help to improve and guide immediate goal-directed therapy to improve cardiogenic shock patients' outcomes.

Rationale and design of the ULYSS trial: A randomized multicenter evaluation of the efficacy of early Impella CP implantation in acute coronary syndrome complicated by cardiogenic shock.

CONTEXT: Despite 20 years of improvement in acute coronary syndromes care, patients with acute myocardial infarction complicated by cardiogenic shock (AMICS) remains a major clinical challenge with a stable incidence and mortality. While intra-aortic balloon pump (IABP) did not meet its expectations, percutaneous mechanical circulatory supports (pMCS) with higher hemodynamic support, large availability and quick implementation may improve AMICS prognosis by enabling early hemodynamic stabilization and unloading. Both interventional and observational studies suggested a clinical benefit in selected patients of the IMPELLAⓇ CP device within in a well-defined therapeutic strategy. While promising, these preliminary results are challenged by others suggesting a higher rate of complications and possible poorer outcome. Given these conflicting data and its high cost, a randomized clinical trial is warranted to delineate the benefits and risks of this new therapeutic strategy. DESIGN: The ULYSS trial is a prospective randomized open label, 2 parallel multicenter clinical trial that plans to enroll patients with AMICS for whom an emergent percutaneous coronary intervention (PCI) is intended. Patients will be randomized to an experimental therapeutic strategy with pre-PCI implantation of an IMPELLAⓇ CP device on top of standard medical therapy or to a control group undergoing PCI and standard medical therapy. The primary objective of this study is to compare the efficacy of this experimental strategy by a composite end point of death, need to escalate to ECMO, long-term left ventricular assist device or heart transplantation at 1 month. Among secondary objectives 1-year efficacy, safety and cost effectiveness will be assessed. CLINICAL TRIAL REGISTRATION: NCT05366452.

Cardiogenic shock in adults with congenital heart disease: Insights from the FRENSHOCK registry.

BACKGROUND: Data on cardiogenic shock in adults with congenital heart disease (ACHD) are scarce. AIM: We sought to describe cardiogenic shock in ACHD patients in a nationwide cardiogenic shock registry. METHODS: From the multicentric FRENSHOCK registry (772 patients with cardiogenic shock from 49 French centres between April and October 2016), ACHD patients were compared with adults without congenital heart disease (non-ACHD). The primary outcome was defined by all-cause mortality, chronic ventricular assist device or heart transplantation at 1year. RESULTS: Out of the 772 patients, seven (0.9%) were ACHD, who were younger (median age: 56 vs. 67years), had fewer cardiovascular risk factors, such as hypertension (14.3% vs. 47.5%) and diabetes (14.3% vs. 28.3%), and no previous ischaemic cardiopathy (0 vs. 61.5%). Right heart catheterization (57.1% vs. 15.4%), pacemakers (28.6% vs. 4.6%) and implantable cardioverter-defibrillators (28.6% vs. 4.8%) were indicated more frequently in the management of ACHD patients compared with non-ACHD patients, whereas temporary mechanical circulatory support (0 vs. 18.7%) and invasive mechanical ventilation (14.3% vs. 38.1%) were less likely to be used in ACHD patients. At 1year, the primary outcome occurred in 85.7% (95% confidence interval: 42.1-99.6) ACHD patients and 52.3% (95% confidence interval: 48.7-55.9) non-ACHD patients. Although 1-year mortality was not significantly different between ACHD patients (42.9%) and non-ACHD patients (45.4%), ventricular assist devices and heart transplantation tended to be more frequent in the ACHD group. CONCLUSIONS: Cardiogenic shock in ACHD patients is rare, accounting for only 0.9% of an unselected cardiogenic shock population. Despite being younger and having fewer co-morbidities, the prognosis of ACHD patients with cardiogenic shock remains severe, and is similar to that of other patients.

Characteristics, management, and outcomes of active cancer patients with cardiogenic shock.

AIMS: Characteristics, management, and outcomes of patients with active cancer admitted for cardiogenic shock remain largely unknown. This study aimed to address this issue and identify the determinants of 30-day and 1-year mortality in a large cardiogenic shock cohort of all aetiologies. METHODS AND RESULTS: FRENSHOCK is a prospective multicenter observational registry conducted in French critical care units between April and October 2016. 'Active cancer' was defined as a malignancy diagnosed within the previous weeks with planned or ongoing anticancer therapy. Among the 772 enrolled patients (mean age 65.7 ± 14.9 years; 71.5% male), 51 (6.6%) had active cancer. Among them, the main cancer types were solid cancers (60.8%), and hematological malignancies (27.5%). Solid cancers were mainly urogenital (21.6%), gastrointestinal (15.7%), and lung cancer (9.8%). Medical history, clinical presentation, and baseline echocardiography were almost the same between groups. In-hospital management significantly differed: patients with cancers received more catecholamines or inotropes (norepinephrine 72% vs. 52%, P = 0.005 and norepinephrine-dobutamine combination 64.7% vs. 44.5%, P = 0.005), but had less mechanical circulatory support (5.9% vs. 19.5%, P = 0.016). They presented a similar 30-day mortality rate (29% vs. 26%) but a significantly higher mortality at 1-year (70.6% vs. 45.2%, P < 0.001). In multivariable analysis, active cancer was not associated with 30-day mortality but was significantly associated with 1-year mortality in 30-day survivors [HR 3.61 (1.29-10.11), P = 0.015]. CONCLUSION: Active cancer patients accounted for almost 7% of all cases of cardiogenic shock. Early mortality was the same regardless of active cancer or not, whereas long-term mortality was significantly increased in patients with active cancer.

Conductive disturbances in the transcatheter aortic valve implantation setting: An appraisal of current knowledge and unmet needs.

New-onset conduction disturbances, including left bundle branch block and permanent pacemaker implantation, remain a major issue after transcatheter aortic valve implantation. Preprocedural risk assessment in current practice is most often limited to evaluation of the baseline electrocardiogram, whereas it may benefit from a multimodal approach, including ambulatory electrocardiogram monitoring and multidetector computed tomography. Physicians may encounter equivocal situations during the hospital phase, and the management of follow-up is not fully defined, despite the publication of several expert consensuses and the inclusion of recommendations regarding the role of electrophysiology studies and postprocedural monitoring in recent guidelines. This review provides an overview of current knowledge and future perspectives regarding the management of new-onset conduction disturbances in the setting of transcatheter aortic valve implantation, from the preprocedural phase to long-term follow-up.

Expanding the Spectrum of TEER Suitability: Evidence From the EXPAND G4 Post Approval Study.

BACKGROUND: Anatomical and clinical criteria to define mitral transcatheter edge-to-edge repair (TEER) "unsuitability" have been proposed on the basis of a Heart Valve Collaboratory consensus opinion from physician experience with early-generation TEER devices but lacked an evidence-based approach. OBJECTIVES: The aim of this study was to explore the spectrum of TEER suitability using echocardiographic and clinical outcomes from the EXPAND G4 real-world postapproval study. METHODS: EXPAND G4 is a global, prospective, multicenter, single-arm study that enrolled 1,164 subjects with mitral regurgitation (MR) treated with the MitraClip G4 System. Three groups were defined using the Heart Valve Collaboratory TEER unsuitability criteria: 1) risk of stenosis (RoS); 2) risk of inadequate MR reduction (RoIR); and 3) subjects with baseline moderate or less MR (MMR). A TEER-suitable (TS) group was defined by the absence of these characteristics. Endpoints included independent core laboratory-assessed echocardiographic characteristics, procedural outcomes, MR reduction, NYHA functional class, Kansas City Cardiomyopathy Questionnaire score, and major adverse events through 30 days. RESULTS: Subjects in the RoS (n = 56), RoIR (n = 54), MMR (n = 326), and TS (n = 303) groups had high 30-day MR reduction rates (≤1+: RoS 97%, MMR 93%, and TS 91%; ≤2+: RoIR 94%). Thirty-day improvements in functional capacity (NYHA functional class I or II at 30 days vs baseline: RoS 94% vs 29%, RoIR 88% vs 30%, MMR 79% vs 26%, and TS 83% vs 33%) and quality of life (change in Kansas City Cardiomyopathy Questionnaire score: RoS +27 ± 26, RoIR +16 ± 26, MMR +19 ± 26, and TS +19 ± 24) were safely achieved in all groups, with low major adverse events (<3%) and all-cause mortality (RoS 1.8%, RoIR 0%, MMR 1.5%, and TS 1.3%). CONCLUSIONS: Patients previously deemed TEER unsuitable can be safely and effectively treated with the mitral TEER fourth-generation device.
