RESUMEN
Aim: Right ventricular failure (RVF) complicates 30-50% of cases with inferior wall myocardial infarctions (IWMI). Large-scale studies exploring the recent trends in morbidity and mortality of IWMI with RVF in the context of improved reperfusion strategies are currently lacking. Materials & methods: The International Classification of Diseases, Tenth Revision, Clinical Modification codes were used to query the National Inpatient Sample of 2018-2019 to yield IWMI admissions and stratified based on presence of RVF. The primary outcome was in-hospital mortality. Results: Out of the 182,485 weighed hospital admissions for IWMI, 1005 patients (0.6%) also had RVF. Patients with both IWMI and RVF had significantly higher mortality than patients with IWMI and no RVF (p < 0.001). Conclusion: RVF in patients with IWMI is an independent predictor of poor outcomes.
What is this article about? Right ventricular failure (RVF) refers to a condition in which the right ventricle is unable to pump blood to the left side of the heart. Up to 3050% of patients with heart attacks, commonly known as acute myocardial infarction, affecting the back or the inferior wall of the heart (IWMI) can develop RVF. Research studies assessing the outcomes of patients with IWMI and RVF were done either in a small number of patients or done during the time when the current standard of acute myocardial infarction care was not the standard of care. Therefore, we conducted a study to assess the clinical outcomes of patients with IWMI and RVF in contemporary times.What are the results? We found that among all patients with IWMI, only about 0.6% had evidence of RVF. However, these patients were older and much more likely to have a higher burden of chronic medical problems and were less likely to have received angioplasty to open blocked arteries when compared with patients with IWMI and no RVF. Patients with IWMI and RVF were noticed to have a higher rate of death during hospitalization.What do the results mean? Patients with IWMI and RVF, when compared with patients with IWMI and no RVF, had significantly higher rates of various complications and death.
RESUMEN
Alcohol septal ablation (ASA) is a well-established procedure for septal reduction therapy in patients with obstructive hypertrophic cardiomyopathy, significant at rest or provocable outflow tract gradients, and medically refractory symptoms. This percutaneous approach to relief of obstruction and eventual cardiac remodeling involves the infusion of a small quantity of ethanol into an appropriately targeted septal artery that is feeding the basal septum to create an iatrogenic and controlled focal infarction. Early akinesia is followed by subsequent thinning and remodeling, which widens the outflow tract, reducing or eliminating the obstruction. Historically, the use of ASA was reserved primarily for high-risk surgical candidates; however, more contemporary data suggest similar outcomes in the short-term and long-term safety of the procedure and overall effectiveness in relieving obstructive symptoms when it is performed in broader populations at experienced centers. Therefore, the current guidelines published in 2020 support ASA as a class 1 indication, similar to its open-heart surgical counterpart, surgical myectomy, when no concomitant significant coronary or valve surgical indication exists. This article summarizes contemporary management of patients with hypertrophic cardiomyopathy who were selected for ASA and details procedural methods and outcomes.

BACKGROUND: Despite the initial evidence supporting the utility of intravascular imaging to guide percutaneous coronary intervention (PCI), adoption remains low. Recent new trial data have become available. An updated study-level meta-analysis comparing intravascular imaging to angiography to guide PCI was performed. This study aimed to evaluate the clinical outcomes of intravascular imaging-guided PCI compared with angiography-guided PCI. METHODS AND RESULTS: A random-effects meta-analysis was performed on the basis of the intention-to-treat principle. The primary outcomes were major adverse cardiac events, cardiac death, and all-cause death. Mixed-effects meta-regression was performed to investigate the impact of complex PCI on the primary outcomes. A total of 16 trials with 7814 patients were included. The weighted mean follow-up duration was 28.8 months. Intravascular imaging led to a lower risk of major adverse cardiac events (relative risk [RR], 0.67 [95% CI, 0.55-0.82]; P<0.001), cardiac death (RR, 0.49 [95% CI, 0.34-0.71]; P<0.001), stent thrombosis (RR, 0.63 [95% CI, 0.40-0.99]; P=0.046), target-lesion revascularization (RR, 0.67 [95% CI, 0.49-0.91]; P=0.01), and target-vessel revascularization (RR, 0.60 [95% CI, 0.45-0.80]; P<0.001). In complex lesion subsets, the point estimate for imaging-guided PCI compared with angiography-guided PCI for all-cause death was a RR of 0.75 (95% CI, 0.55-1.02; P=0.07). CONCLUSIONS: In patients undergoing PCI, intravascular imaging is associated with reductions in major adverse cardiac events, cardiac death, stent thrombosis, target-lesion revascularization, and target-vessel revascularization. The magnitude of benefit is large and consistent across all included studies. There may also be benefits in all-cause death, particularly in complex lesion subsets. These results support the use of intravascular imaging as standard of care and updates of clinical guidelines.

BACKGROUND: Chronic kidney disease (CKD) and end-stage renal disease (ESRD) have been associated with worse outcomes after transcatheter aortic valve replacement (TAVR). With TAVR indications extending to a wider range of patient populations, it is important to understand the current implications of chronic renal insufficiency on clinical outcomes. We aim to determine the impact of CKD and ESRD on in-hospital outcomes after TAVR. METHODS: We queried the National Inpatient Sample for TAVR performed between 2016 and 2020 using International Classification of Diseases-10th Revision codes. We compared in-hospital mortality and clinical outcomes between three groups: normal renal function, CKD and ESRD. The association between CKD/ESRD and outcomes was tested with multivariable logistic regression analyses, using normal renal function as baseline. RESULTS: In the five-year study period, 279,195 patients underwent TAVR (mean age 78.9 ± 8.5 years, 44.4% female). Of all patients, 67.1% had normal renal function, 29.2% had CKD, and 3.7% had ESRD. There were significant differences in age, sex, and prevalence of comorbidities across groups. In-hospital mortality was 1.3%. Compared to patients with normal renal function, patients with renal insufficiency had higher in-hospital mortality, with the highest risk found in patients with ESRD (adjusted odds ratio: 1.4 [95% confidence interval: 1.2-1.7] for CKD; adjusted odds ratio: 2.4 [95% confidence interval: 1.8-3.3] for ESRD). Patients with CKD or ESRD had a higher risk of cardiogenic shock, need for mechanical circulatory support, and vascular access complications, compared to those with normal renal function. In addition, patients with ESRD had a higher risk of cardiac arrest and periprocedural acute myocardial infarction. The incidence of conversion to open heart surgery was 0.3% and did not differ between groups. Post-procedural infectious and respiratory complications were more common among patients with CKD or ESRD. CONCLUSION: Patients with CKD and ESRD are at higher risk of in-hospital mortality, cardiovascular, and non-cardiovascular complications after TAVR. The risk of complications is highest in patients with ESRD and does not result in more frequent conversion to open heart surgery. These results emphasize the importance of individualized patient selection for TAVR and procedural planning among patients with chronic renal insufficiency.

Coronary bifurcation lesions are frequent challenging findings during percutaneous coronary intervention (PCI). Contemporary evidence has explored the potential sex-specific differences in patients undergoing PCI. In the present meta-analysis, we compared clinical outcomes of patients undergoing bifurcation PCI between women and men. Using the random-effects method, we compared the clinical outcomes of patients with a coronary bifurcation lesion following PCI between women and men. The results were reported using relative risk (RR) and 95% confidence interval (CI). Baseline comorbidities and mean age were compared between the 2 studied groups. Four observational studies comprising 30,684 patients (8898 women and 21,786 men) were included in the meta-analysis. Women were significantly older than men with a relatively higher prevalence of baseline comorbidities. After using adjusted data from 2 out of 4 available studies, performing PCI for bifurcation lesions in women was not associated with an increased risk of mortality (RR 1.33, 95% CI, 0.78-2.29), myocardial infarction (RR 1.22, 95% CI, 0.41-3.61), target lesion revascularization (RR 1.06, 95% CI, 0.40-2.81), stent thrombosis (RR 0.99, 95% CI, 0.09-10.52), and stroke (RR 1.19, 95% CI, 0.64-2.22). Women were at higher risk of major bleeding compared to male counterparts (RR 2.23, 95% CI, 1.73-2.89). The present study showed no difference in the risk of adverse clinical outcomes except the risk of bleeding between genders with coronary bifurcation lesions. Future studies with adjustment of age and baseline comorbidities are needed to confirm these findings.
RESUMEN
Background Data on clinical outcomes after transcatheter aortic valve replacement (TAVR) in specific cancer types or the presence of metastatic disease remain sparse. This study aimed to investigate the impact of active cancer on short-term mortality, complications, and readmission rates after TAVR across different cancer types. Methods and Results The authors assessed the Nationwide Readmissions Database for TAVR cases from 2012 to 2019. Patients were stratified by specific cancer types. Primary outcome was in-hospital mortality. Secondary outcomes included bleeding requiring blood transfusion and readmissions at 30, 90, and 180 days after TAVR. Overall, 122 573 patients undergoing TAVR were included in the analysis, of whom 8013 (6.5%) had active cancer. After adjusting for potential confounders, the presence of active cancer was not associated with increased in-hospital mortality (adjusted odds ratio [aOR], 1.06 [95% CI, 0.89-1.27]; P=0.523). However, active cancer was associated with an increased risk of readmission at 30, 90, and 180 days after TAVR and increased risk of bleeding requiring transfusion at 30 days. Active colon and any type of metastatic cancer were individually associated with readmissions at 30, 90, and 180 days after TAVR. At 30 days after TAVR, colon (aOR, 2.51 [95% CI, 1.68-3.76]; P<0.001), prostate (aOR, 1.40 [95% CI, 1.05-1.86]; P=0.021), and any type of metastatic cancer (aOR, 1.65 [95% CI, 1.23-2.22]; P=0.001) were individually associated with an increased risk of bleeding requiring transfusion. Conclusions Patients with active cancer had similar in-hospital mortality after TAVR but higher risk of readmission and bleeding requiring transfusion, the latter depending on certain types of cancer.

BACKGROUND: Bicuspid aortic valve (BAV) is present in approximately 0.5%-2% of the general population, causing significant aortic stenosis (AS) in 12%-37% of affected individuals. Transcatheter aortic valve replacement (TAVR) is being considered the treatment of choice in patients with symptomatic AS across all risk spectra. AIM: Aim Our study aims to compare TAVR outcomes in patients with BAV versus tricuspid aortic valves (TAV). METHODS: A comprehensive literature search was performed in PubMed, Web of Science, and Cochrane trials. Studies were included if they included BAV and TAV patients undergoing TAVR with quantitative data available for at least one of our predefined outcomes. Meta-analysis was performed by the random-effects model using Stata software. RESULTS: Fifty studies of 203,288 patients were included. BAV patients had increased 30-day all-cause mortality (odds ratio [OR] = 1.23 [1.00-1.50], p = 0.05), in-hospital stroke (OR = 1.39 [1.01-1.93], p = 0.05), in-hospital and 30-day PPI (OR = 1.13 [1.00-1.27], p = 0.04; OR = 1.16 [1.04-1.13], p = 0.01) and in-hospital, 30-day and 1-year aortic regurgitation (AR) (OR = 1.48 [1.19-1.83], p < 0.01; OR = 1.79 [1.26-2.52], p < 0.01; OR = 1.64 [1.03-2.60], p = 0.04). Subgroup analysis on new-generation valves showed a reduced 1-year all-cause mortality (OR = 0.86 [CI = 0.75-0.98], p = 0.03), despite higher in-hospital and 30-day PPI (OR = 0.1.21 [1.04-1.41], p = 0.01; OR = 1.17 [1.05-1.31], p = 0.01) and in-hospital AR (OR = 1.62 [1.14-2.31], p = 0.01) in the BAV group. The quality of included studies was moderate-to-high, and only three analyses presented high heterogeneity. CONCLUSION: TAVR is associated with comparable outcomes in patients with BAV and TAV. Careful selection of BAV cases by preprocedural assessment of valve anatomy and burden of calcification, pre- and post-procedural dilation, and implementing newer generations of valves may improve the safety and efficacy of TAVR in BAV patients.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) generally causes milder illness in the pediatric population. However, infants represent a higher-risk population with evolving symptomatology and severity. There is a paucity of large population-based data on the impact of COVID-19 on hospitalized infants. STUDY DESIGN: In this large cohort study, the National Inpatient Sample database was queried for all infant hospital admissions between January and December 2020 in the United States, with and without a diagnosis of COVID-19 based on ICD-10-CM U07. The mortality and morbidity of infants with and without COVID-19 were evaluated. Parent-reported race and outcomes were also analyzed. RESULTS: A weighted total of 3,754,236 infants who were hospitalized were identified, of which 4,265 patients (0.11%) had a concomitant diagnosis of COVID-19. Infants with COVID-19 had similar mortality and extracorporeal membrane oxygenation utilization. Infants with concomitant COVID-19 had a higher rate of respiratory failure, congestive heart failure, acute kidney injury, and coagulopathy. Compared with Caucasian infants and Asian infants, Hispanic and African American infants were more likely to have COVID-19 hospital admissions than hospitalizations without COVID-19 diagnosis. Patients with lower median household income represented the majority of the COVID-19 hospitalization. The infants with COVID-19 were more likely to have Medicaid or Medicare insurance and less likely to have private insurance. CONCLUSION: In this large cohort of hospitalized infants with COVID-19, the infection was associated with complications, including respiratory failure and endotracheal intubations but not associated with a higher risk for mortality. Infants from racial minorities and lower socioeconomic strata carry the highest burden of COVID-19 infection. KEY POINTS: · Infants with COVID-19 represent a higher-risk group with evolving symptomatology and severity.. · Infants with COVID-19 had similar mortality rates and extracorporeal membrane oxygenation utilization as those without COVID-19.. · Racial minorities and lower socioeconomic strata carry the highest burden of COVID-19 infection..
RESUMEN
Remdesivir has been used for coronavirus disease 2019 (COVID-19) pneumonia with oxygen requirements that do not require mechanical intubation, and several studies showed a reduction in disease duration. However, there is a concern about bradycardia as its side effect. We aimed to investigate the association between Remdesivir and bradycardia by integrating findings from prior studies. We queried PubMed and EMBASE in February 2023 and performed a meta-analysis of studies investigating bradycardia in patients who did or did not receive Remdesivir. The outcome of interest was the rate of bradycardia and in-hospital mortality. We identified eight studies involving 8993 patients, of which seven studies investigated bradycardia. Six studies were observational, one was a case-control, and one was a randomized trial. Incidence of bradycardia was 400/3480 patients (22.3%, 95% confidence interval, CI: [6.5-54.4], I2 = 99%) in the Remdesivir group and 294/5005 (9.8%, 95% CI: [2.8-29], I2 = 98.61) in the non-Remdesivir group. The odds ratio of bradycardia was 2.11 (95% CI: [1.65-2.71], I2 = 22%, p < 0.001) for the Remdesivir group. There was no difference in mortality between the two groups. Patients who received Remdesivir for COVID-19 were more likely to develop bradycardia. The effect of confounding factors should be considered to further clarify the possible association.

Extracorporeal membrane oxygenation (ECMO) has been used for COVID-19-associated acute respiratory distress syndrome (ARDS). We aimed to elucidate the association between ECMO and mortality in patients with COVID-19-associated ARDS in the nationwide setting. United States National Inpatient Sample was used to identify mechanically ventilated adults for COVID-19 with ARDS. We divided them into three groups according to the use of ECMO (i.e., no-ECMO, venovenous [VV]-ECMO, and venoarterial [VA]-ECMO). The primary outcome was in-hospital mortality, while the secondary outcomes included the length of hospital stay (LOS) and the total costs during hospitalization. We performed a stepwise logistic regression, adjusting for baseline characteristics, comorbidities, and severity. We included 68 795 (mean age [SD]: 63.5 [0.1]), 3280 (mean age [SD]: 48.7 [0.5]), and 340 (mean age [SD]: 43.3 [2.1]) patients who received no-, VV-, and VA-ECMO, respectively. The logistic regression analysis did not show significant associations between the use of VV-/VA-ECMO and mortality (adjusted odds ratio with no-ECMO as reference [95% confidence interval]: 1.03 [0.86-1.24] and 1.18 [0.64-2.15], respectively). While LOS was longest with VV-ECMO, the total costs were highest with VA-ECMO. In conclusion, our study found no association between the use of ECMO and mortality of COVID-19-associated ARDS in the nationwide setting.

BACKGROUND: Various durations and de-escalation strategies of dual antiplatelet therapy (DAPT) after ST-elevation myocardial infarction (STEMI) or non-ST-elevation acute coronary syndromes (NSTE-ACS) have been tested in randomized controlled trials (RCT)s. However, evidence by specific ACS subtype is unknown. METHODS: PubMed, EMBASE, and Cochrane CENTRAL were searched in February 2023. RCTs on DAPT strategies included STEMI or NSTE-ACS patients with standard DAPT (12 months) with clopidogrel or potent P2Y12 inhibitors, short-term DAPT (≤6 months) followed by potent P2Y12 inhibitors or aspirin, unguided de-escalation from potent P2Y12 inhibitors to low-dose potent P2Y12 inhibitors or clopidogrel at one month, and guided selection with genotype or platelet function tests were identified. The primary outcome was the net adverse clinical events (NACE) defined as a composite of major adverse cardiovascular events (MACE) and clinically relevant bleeding events. RESULTS: Twenty RCTs with a combined total population of 24,745 STEMI and 37,891 NSTE-ACS patients were included. In STEMI patients, unguided de-escalation strategy was associated with a lower rate of NACE compared with standard DAPT using potent P2Y12 inhibitors (HR:0.57; 95% CI:0.34-0.96) without increased risk of MACE. In NSTE-ACS patients, unguided de-escalation strategy was associated with a lower rate of NACE compared with the guided selection strategy (HR:0.65; 95% CI:0.47-0.90), standard DAPT using potent P2Y12 inhibitors (HR:0.62; 95% CI:0.50-0.78) and standard DAPT using clopidogrel (HR:0.73; 95% CI:0.55-0.98) without increased risk of MACE. CONCLUSION: Unguided de-escalation strategy was associated with a reduced risk of NACE and may be the most effective DAPT strategy for STEMI and NSTE-ACS.

Introduction: The presence of chronic obstructive pulmonary disease (COPD) can impact the management of acute myocardial infarction (AMI) and is associated with higher mortality. Few studies addressed COPD impact on heart failure hospitalisations (HFHs) in AMI survivors. Material and methods: Adult survivors of an AMI between January and June 2014 were identified from the US Nationwide Readmissions Database. The impact of COPD on HFH within 6 months, fatal HFH and the composite of in-hospital HF or 6-month HFH was studied. Results: Of 237,549 AMI survivors, patients with COPD (17.5%) were older, more likely female, had a higher prevalence of cardiac comorbidities and a lower coronary revascularization rate. In-hospital HF was more frequent in patients with COPD (47.0% vs. 25.4%; p < 0.001). HFH within 6 months occured in 12,934 (5.4%) patients, at a 114% higher rate in patients with COPD (9.4% vs. 4.6%, OR = 2.14, 95% CI : 2.01-2.29; p < 0.001), which was attenuated to a 39% higher adjusted risk (OR = 1.39, 95% CI: 1.30-1.49). Findings were consistent across subgroups of age, AMI type, and major HF risk factors. Mortality during a HFH (5.7% vs. 4.2%, p < 0.001) and the rate of the composite HF outcome (49.0% vs. 26.9%, p < 0.001) were significantly higher in patients with COPD. Conclusions: COPD was present in 1 of 6 AMI survivors and was associated with worse HF related outcomes. The increased HFH rate in COPD patients was consistent across several clinically relevant subgroups and these findings highlight the need for optimal in-hospital and post-discharge management of these higher-risk patients.
RESUMEN
Influenza vaccination has shown great promise in terms of its cardioprotective effects. The aim of our analysis is to provide evidence regarding the protective effects of influenza vaccination in patients with cardiovascular disease. We conducted a systematic literature search to identify trials assessing the cardiovascular outcomes of influenza vaccination. Summary effects were calculated using a DerSimonian and Laird fixed effects and random effects model as odds ratio with 95% confidence intervals (CIs) for all the clinical endpoints. Fifteen studies with a total of 745,001 patients were included in our analysis. There was lower rates of all-cause mortality [odds ratio (OR) = 0.74, 95% CI 0.64-0.86], cardiovascular death (OR = 0.73, 95% CI 0.59-0.92), and stroke (OR = 0.71, 95% CI 0.57-0.89) in patients who received the influenza vaccine compared to placebo. There was no significant statistical difference in rates of myocardial infarction (OR = 0.91, 95% CI 0.69-1.21) or heart failure hospitalizations (OR = 1.06, 95% CI 0.85-1.31) in the 2 cohorts. In patients with cardiovascular disease, influenza vaccination is associated with lower all-cause mortality, cardiovascular death, and stroke.
RESUMEN
Sarcoidosis, amyloidosis, hemochromatosis and scleroderma are the most forms of infiltrative/nonischemic cardiomyopathy (NICM) associated with sudden cardiac death. In patients who undergo in-hospital cardiac arrest, a high index of suspicion is required to rule out NICM as an underlying contributor. We aimed to analyze the prevalence of NICM among patients with in-hospital cardiac arrest and identify factors associated with increased mortality. We analyzed data from the National Inpatient Sample, and identified patients who were hospitalized across 10 years from 2010 to 2019 with a diagnosis of cardiac arrest and NICM. The total number of patients with in-hospital cardiac arrest was 19,34,260. The total number with NICM was 14,803 (0.77%). Mean age was 63 years. Overall prevalence of NICM across the years ranged between 0.75% to 0.9%, with a significant temporal increase (P < 0.01). Incidence of in-hospital mortality ranged between 61% to 76% for females and 30% to 38% for males. The following comorbidities were more prevalent in patients with NICM than those without: heart failure, chronic obstructive pulmonary disease (COPD), chronic kidney disease, anemia, malignancy, coagulopathy, ventricular tachycardia, acute kidney injury and stroke. The following factors were independent predictors of in-hospital mortality-age, female gender, Hispanic race, history of COPD and presence of malignancy (Pâ¯=â¯0.042). The prevalence of infiltrative cardiomyopathy in patients with in-hospital cardiac arrest is increasing. Females, older patients and Hispanic population are at an increased risk of mortality. Sex and race-based disparities in the prevalence of NICM in patients with in-hospital cardiac arrest is an area of further research.

Out-of-hospital cardiac arrest has a high mortality rate. Unlike ST-elevation myocardial infarction, the results of performing early coronary angiography (CAG) in non-ST-elevation myocardial infarction patients are controversial. This study aimed to compare early and nonearly CAG in this population, in addition to the identification of differences between randomized controlled trials (RCTs) and observational studies conducted in this regard. A systematic search in PubMed, Embase, and Cochrane library was performed to identify the relevant studies. Random-effect meta-analysis was done to calculate the pooled effect size of early versus nonearly CAG outcomes in all studies in addition to each of the RCT and observational subgroups of the studies. The relative risk ratio (RR), along with its 95% confidence interval (CI), was used as a measure of difference. A total of 16 studies including 5234 cases were included in our analyses. Compared with observational cohorts, RCT studies had patients with higher baseline comorbidities (older age, hypertension, diabetes, and coronary artery disease). Random-effect analysis revealed a lower rate of in-hospital mortality in the early-CAG group (RR, 0.79; 95% CI, 0.65-0.97; P = 0.02); however, RCT studies did not find a statistical difference in this outcome (RR, 1.01; 95% CI, 0.83-1.23; P = 0.91). Moreover, mid-term mortality rates were lower in the early-CAG group (RR, 0.87; 95% CI, 0.78-0.98; P = 0.02), mostly due to observational studies. There was no significant difference between the groups in other efficacy and safety outcomes. Although early CAG was associated with lower in-hospital and mid-term mortality in overall analyses, no such difference was confirmed by the results obtained from RCTs. Current evidence from RCTs may not be representative of real-world patients and should be interpreted within its limitation.
RESUMEN
BACKGROUND: Transcatheter edge-to-edge repair (TEER) of the mitral valve has become an established therapy for certain patients with mitral regurgitation. However, little is known about the association between institutional volume variations and long-term outcomes using a large-scale database. Our study aimed to describe the institutional variations of TEER and also investigate its association with 180-day readmission rates. METHODS: We conducted a retrospective cohort study of TEER performed in the US from the 2019 Nationwide Readmission Database. We divided the patients according to the tertiles based on volume of TEER (Q1 [lowest]-Q3 [highest]) and evaluated the association with 180-day readmission rates. RESULTS: A total of 4922 patients (mean age 76.8 ± 10.4 years, and 54.5% male) who underwent TEER at 250 institutions were included in the analyses. There was substantial variation in the number of TEER performed annually across institutions (median 25.0 [11.6-52.5] cases). Readmission within 6-months following TEER was 37.0%, mainly due to heart failure. Higher institutional volume was associated with a reduced incidence of 180-day readmissions (HR of Q3 0.68 95%CI 0.50-0.93, vs Q1; p = 0.016). This association was more prominent in non-elective cases (HR of Q3 0.50 95%CI 0.31-0.81, vs Q1; p = 0.005). CONCLUSIONS: Using a nationally representative contemporary database, our study found substantial institutional variation in volume of TEER cases. Higher institutional volume was associated with a decreased risk of 180-day readmission rate, particularly in non-elective cases. Our study suggests the importance of highly skilled heart teams when treating patients who need urgent transcatheter intervention for mitral regurgitation.

We aimed to compare the characteristics and outcomes of adult patients hospitalized with myocarditis and either concomitant corona virus disease 2019 (COVID-19) or influenza, and elucidate clinical predictors associated with adverse outcomes in both groups. The study used the national inpatient sample (NIS) from 2019 to 2020 to identify 27,725 adult myocarditis hospitalizations, of which 5840 had concomitant COVID-19 and 1045 had concomitant influenza. After propensity score matching, the in-hospital mortality from myocarditis was significantly higher in COVID-19 compared to influenza. Patients with myocarditis and COVID-19 were more likely to have cardiovascular comorbidities and be older than those with influenza-associated myocarditis. Predictors of mortality were also different in both groups.
