RESUMO
Peripartum cardiomyopathy (PPCM) is a rare but potentially life-threatening form of heart failure (HF). Bromocriptine, a dopamine D2 agonist, has been used as an adjunctive treatment for PPCM with controversial benefits. A comprehensive literature search was conducted through June 2021. We included studies comparing the outcomes of PPCM with or without bromocriptine use. Pooled risk ratio (RR) with 95% confidence intervals (CI) and I2 statistics were calculated. Composite major adverse outcomes were defined by a composite of death, need for advanced HF therapies, persistent New York Heart Association (NYHA) functional class III/V, or left ventricular ejection fraction (LVEF) ≤ 35% at 6-month follow-up. LVEF recovery was defined by improvement of LVEF to more than 50%. Eight studies (two randomized-controlled, six observational) involving 593 PPCM patients were included. Bromocriptine use was associated with significantly higher survival (91.6% vs. 83.9%, RR 1.11 p = 0.02). Baseline LVEF was not significantly different between the groups. LVEF at follow-up was significantly higher in the bromocriptine group (53.3% vs. 41.8%, p < 0.001). There was no significant association between bromocriptine use and lower composite major adverse outcomes (13.7% vs. 33.3%, RR 0.60 p = 0.54) or LVEF recovery (46.9% vs. 46.8%, RR 0.94 p = 0.74). In conclusion, the addition of bromocriptine to standard HF treatment in PPCM was associated with significantly higher survival and higher LVEF improvement. No association with lower composite adverse clinical outcomes or LVEF recovery was seen. The findings, although encouraging, warrant larger randomized-controlled studies.

Temporary right ventricular pacing in unstable bradycardia and cardiovascular interventions is associated with atrioventricular dyssynchrony and reduced cardiac output. Currently, sequential atrioventricular pacing options are limited andnot routinely used. Herein, we discuss a novel, first in-human technique of temporary atrioventricular sequential pacing and how it compares to existing modalities of atrioventricular pacing.

BACKGROUND: Right ventricular failure (RVF) remains a major cause of morbidity and mortality after left ventricular assist device (LVAD). Atrial fibrillation (AF) is known for its deleterious effects on cardiac function and hemodynamics. The association of pre-operative AF with the risk of early post-LVAD RVF has not been well described. METHOD: A comprehensive literature search was performed through April, 9 2021. Cohort studies comparing the risk of post-operative RVF and/or need for right ventricular assist device (RVAD) after LVAD in patients with or without AF were included. Pooled odds ratio (OR) with 95% confidence intervals (CI) and I2 statistic were calculated using the random-effects model. RESULTS: Six studies were included in the analysis. Post-operative RVF was reported in 5 studies (1,841 patients) and RVAD use was reported in 4 studies (1,355 patients). There is a non-significant trend toward a higher risk of post-operative RVF in the AF group (pooled OR=1.25, 95%CI=0.99-1.58). No significant association between AF and RVAD use is noted (pooled OR=1.17, 95%CI=0.82-1.66). CONCLUSIONS: Pre-operative AF is not significantly associated with higher risks of post-operative RVF and RVAD use after LVAD implantation, although the trend toward higher post-operative RVF is observed in patients with pre-operative AF. Additional research using a larger study population is warranted to better understand the association of pre-operative AF and the development of post-LVAD RVF.

BACKGROUND: Dapagliflozin, a sodium-glucose cotransporter-2 inhibitor, reduces cardiovascular death and worsening heart failure in patients with chronic heart failure and reduced ejection fraction. Early initiation during an acute heart failure (AHF) hospitalization may facilitate decongestion, improve natriuresis, and facilitate safe transition to a beneficial outpatient therapy for both diabetes and heart failure. OBJECTIVE: The objective is to assess the efficacy and safety of initiating dapagliflozin within the first 24 hours of hospitalization in patients with AHF compared to usual care. METHODS: DICTATE-AHF is a prospective, multicenter, open-label, randomized trial enrolling a planned 240 patients in the United States. Patients with type 2 diabetes hospitalized with hypervolemic AHF and an estimated glomerular filtration rate of at least 30 mL/min/1.73m2 are eligible for participation. Patients are randomly assigned 1:1 to dapagliflozin 10 mg once daily or structured usual care until day 5 or hospital discharge. Both treatment arms receive protocolized diuretic and insulin therapies. The primary endpoint is diuretic response expressed as the cumulative change in weight per cumulative loop diuretic dose in 40 mg intravenous furosemide equivalents. Secondary and exploratory endpoints include inpatient worsening AHF, 30-day hospital readmission for AHF or diabetic reasons, change in NT-proBNP, and measures of natriuresis. Safety endpoints include the incidence of hyper/hypoglycemia, ketoacidosis, worsening kidney function, hypovolemic hypotension, and inpatient mortality. CONCLUSIONS: The DICTATE-AHF trial will establish the efficacy and safety of early initiation of dapagliflozin during AHF across both AHF and diabetic outcomes in patients with diabetes.

BACKGROUND: Phosphodiesterase-5 inhibitors (PDE5i) have been used to treat pulmonary hypertension and right ventricular failure in patients with left ventricular assist devices (LVAD). The effects of PDE5i on post-LVAD outcomes including hemocompatibility-related adverse events are not well-established. This systematic review and meta-analysis aims to evaluate the effects of PDE5i on post-LVAD outcomes. METHODS AND RESULTS: A comprehensive literature search was conducted using Pubmed and Embase databases from inception through November 25, 2020, to compare post-LVAD outcomes in patients with or without PDE5i use. Pooled odds ratio (OR) with 95% confidence intervals (CI) and I2 statistic were calculated. Thirteen observational studies were included in this analysis. The use of PDE5i was not significantly associated with lower postoperative right ventricular failure (OR 0.38, 95% CI 0.02-5.96, Pâ¯=â¯.41). There was no significant association between PDE5i and gastrointestinal bleeding (OR 1.23, 95% CI 0.76-1.98, Pâ¯=â¯.2), overall stroke (OR 0.60, 95% CI 0.21-1.68, Pâ¯=â¯.17), ischemic stroke (OR 0.61, 95% CI 0.09-4.07, Pâ¯=â¯.38), or pump thrombosis (OR 0.71, 95% CI 0.14-3.54, Pâ¯=â¯.46). CONCLUSIONS: Our meta-analysis showed no significant association between PDE5i and post-LVAD right ventricular failure. Despite the antiplatelet effects of PDE5i, there was no significant association between PDE5i and gastrointestinal bleeding, overall stroke, ischemic stroke, or pump thrombosis. Randomized controlled studies are warranted to evaluate the net benefits or harms of PDE5i in the LVAD population.

Cardiovascular disease (CVD) remains the leading cause of death in the United States. However, percutaneous interventional cardiovascular therapies are often underutilized in Blacks, Hispanics, and women and may contribute to excess morbidity and mortality in these vulnerable populations. The Society for Cardiovascular Angiography and Interventions (SCAI) is committed to reducing racial, ethnic, and sex-based treatment disparities in interventional cardiology patients. Accordingly, each of the SCAI Clinical Interest Councils (coronary, peripheral, structural, and congenital heart disease [CHD]) participated in the development of this whitepaper addressing disparities in diagnosis, treatment, and outcomes in underserved populations. The councils were charged with summarizing the available data on prevalence, treatment, and outcomes and elucidating potential reasons for any disparities. Given the huge changes in racial and ethnic composition by age in the United States (Figure 1), it was difficult to determine disparities in rates of diagnosis and we expected to find some racial differences in prevalence of disease. For example, since the average age of patients undergoing transcatheter aortic valve replacement (TAVR) is 80 years, one may expect 80% of TAVR patients to be non-Hispanic White. Conversely, only 50% of congenital heart interventions would be expected to be performed in non-Hispanic Whites. Finally, we identified opportunities for SCAI to advance clinical care and equity for our patients, regardless of sex, ethnicity, or race.

INTRODUCTION: Treatment of adult congenital heart disease patients who require advanced therapies remains challenging due to high perioperative and wait-list mortality and limited donors. Patients palliated with Fontan are at the highest risk of early mortality due to multiorgan involvement and few centers able to safely transplant them. We sought to evaluate the early outcomes of heart transplants in these adult Fontan patients. METHODS: Using the Nationwide Inpatient Sample database, we identified all adults aged at least 18 years old who underwent heart transplantation across U.S. hospitals from 2004 to 2014. We then identified those with specific ICD-9 codes to include tricuspid atresia, hypoplastic left heart syndrome and common ventricle. Multivariate regression models were created to adjust for potential confounders. RESULTS: A total of 93 Fontan patients underwent heart transplant during the study time (0.5% of all heart transplants). Compared to non-Fontan heart transplantations, Fontan patients were younger, with a higher incidence of liver disease and coagulopathy. Fontan patients receiving heart transplant had higher mortality during transplant hospitalization compared to non-Fontan patients (26.3% vs 5.3% OR, 18.10, CI, 5.06-65.0 P < .001). Extracorporeal membrane oxygenator (ECMO) usage and bleeding were also higher in the Fontan cohort with an OR of 5.30 (P = .016) and 5.32 (P = .015) for ECMO and bleeding, respectively. The remaining outcomes were similar for both cohorts. CONCLUSION: Adults with Fontan palliation undergoing heart transplantation have exceptionally high inpatient mortality, which is nearly five times that of non-Fontan heart transplant recipients, perhaps related to a delayed referral, surgical complexity, and coexistent, underrecognized liver failure.

BACKGROUND: The pulmonary artery catheter (PAC) has been used in a wide range of critically ill patients. It is not indicated for routine care of heart failure (HF), but its role in cardiogenic shock (CS) has not been clarified. METHODS AND RESULTS: We conducted a retrospective cohort study with the use of the National Inpatient Sample and identified a total of 9,431,944 adult patients admitted from 2004 to 2014 with the primary diagnosis of HF (nâ¯=â¯8,516,528) or who developed CS (nâ¯=â¯915,416) during the index hospitalization. Overall, patients with PAC had increased hospital costs, length of stay, and mechanical circulatory support use. In patients with HF, PAC use was associated with higher mortality (9.9% vs 3.3%, OR 3.96; P < .001) but the excess of mortality declined over time. In those with CS, PAC was associated with lower mortality (35.1% vs 39.2%, OR 0.91; P < .001) and in-hospital cardiac arrest (14.9% vs 18.3%, OR 0.77; P < .001); this paradox persisted after propensity score matching. CONCLUSIONS: The use of PAC in CS has decreased from 2004 to 2014, although its use is now associated with improved outcomes, which may reflect better selection of patients or better use of the information to guide therapies. Our data provide reassurance that PAC use in this population is an appropriate strategy.

BACKGROUND: Despite improvements in acute care and survival after non-ST-elevation acute coronary syndrome (NSTE-ACS) hospitalization, early readmissions remain common, and have significant clinical and financial impact. OBJECTIVES: Determine the predictors and etiologies of 30-day readmissions in NSTE-ACS. METHOD: The study cohort was derived from the National Readmission Database 2014 identifying patients with a primary diagnosis of NSTE-ACS using ICD9 code. RESULTS: We identified a total of 300,269 patients admitted with NSTE-ACS; 13.4% were readmitted within 30-day. The most common cause of readmission was heart failure (HF) (15.6%), followed by a recurrent myocardial infarction (MI) (10%). Predictors of increased readmissions were age ≥ 75 years (OR: 1.34, 95% CI: 1.30-1.39), female gender (OR 1.12, 95% CI 1.09-1.16), a Charlson Comorbidity Index (CCI) >3 (OR 2.11, 95% CI: 2.04-2.18), ESRD (OR 2.01, 95% CI 1.89-2.14), CKD (OR: 1.58, 95% CI: 1.51-1.64), length of stay ≥5 days (OR: 1.51, 95% CI 1.46-1.56) and adverse events during the index admission such as AKI (OR:1.31, 95% CI: 1.25-1.36), major bleeding (OR:1.20, 95% CI: 1.12-1.24); whereas admission to a teaching hospital (OR 0.92, 95% CI 0.89-0.95) and PCI (OR 0.70, 95% CI 0.67-0.72) were associated with less likelihood of 30-day readmission. CONCLUSION: Readmission rate at 30-days is high among NSTE-ACS patients and the most common readmission etiologies are HF and recurrent MI. A CCI more than 3 and ESRD were the most significant predictors for readmission; patients undergoing PCI had less odds of readmission.

Dual antiplatelet therapy with aspirin and a P2Y12 receptor blocker has been proven to reduce subsequent cardiovascular events and in-stent thrombosis in patients undergoing percutaneous coronary intervention. Newer P2Y12 antagonists with faster onset and greater inhibition of platelet activity have improved cardiovascular outcomes but have created uncertainty with the appropriate dosing when switching between agents. Currently, there are no evidence-based guidelines to aid clinicians when switching between P2Y12 receptor blockers. Here we describe two patients that developed in-stent thrombosis when switching from ticagrelor to clopidogrel using a 300 mg clopidogrel loading dose. Both patients presented with ST elevation myocardial infarction and underwent stent placement but then developed in-stent thrombosis 48 hours after switching from ticagrelor to clopidogrel. These cases illustrate the severe consequences of suboptimal platelet inhibition and the need for prospective trials thoroughly powered to assess clinical outcomes in order to determine the most appropriate strategy when switching from ticagrelor to clopidogrel.

Transradial catheterization is associated with lower complication rates; however limited information is available regarding techniques to overcome unusual complications. We present a case of a 58-year-old male with suspected non-ST-elevated myocardial infarction who underwent transradial coronary angiography complicated by guidewire embolization into the radial artery and subsequent access loss. Successful retrieval of the embolized guidewire was achieved by re-accessing the same radial artery and the use of a 2 mm gooseneck microsnare. This technique was safe and prevented the need for surgical intervention or femoral access for retrieval, which are commonly described in the literature and can result in additional complications.

Mechanical circulatory support for cardiogenic shock complicated by acute severe aortic regurgitation poses a unique challenge for traditional veno arterial extracorporeal membrane oxygenation (ECMO) because of rapidly rising left ventricular pressures accentuated by the increased afterload from retrograde flow in femoral cannulation. This process necessitates rapid left ventricular unloading while also allowing for adequate native left ventricular function. Herein, we describe a case of cardiogenic and septic shock secondary to methicillin-resistant Staphylococcus aureus complicated by acute severe aortic regurgitation temporized by left atrial-veno arterial (LA-VA) ECMO via the Livanova TandemHeart system. Left ventricular unloading created a window of hemodynamic stability allowing for optimization of multiorgan failure and infectious source control before surgical aortic valve replacement.

The use of Impella assist device for high-risk percutaneous coronary interventions and cardiogenic shock has increased in the last decade and requires a large bore arterial access (LBA). However, LBA closure following Impella removal is associated with significant complications. Herein, we describe the safety and efficacy of a novel method of LBA closure using arterial recoil following Impella removal. We performed a retrospective review of electronic medical records of patients who underwent LBA closure using this method from July 1, 2018 to June 30, 2022. The procedure involves controlled downsizing of the arterial sheath from 12 French (Fr) to 6 Fr catheters with intermittent compression to allow patent hemostasis facilitated by arterial recoil. Baseline characteristics and outcomes including closure success, immediate/delayed bleeding, and access site complications were included. Of 103 patients with Impella placement, 20 (19%) underwent LBA closure with this method. Patients were predominantly male (80%) and White (55%) with a mean age of 65 ± 16 years. After downsizing of the femoral sheath to 6 Fr, 14 patients underwent manual compression, 3 patients had a 6 Fr catheter left in place to maintain access, and 3 patients underwent placement of a Perclose or Vascade device. Successful LBA closure was performed in all patients with no immediate or delayed bleeding complications. Five patients (25%) died inpatient; the deaths were unrelated to complications of Impella removal. In conclusion, LBA closure post-Impella removal with this novel method was safe and effective. Further prospective studies are needed to ascertain its comparative efficacy.

BACKGROUND: The primary goals during acute heart failure (AHF) hospitalization are decongestion and guideline-directed medical therapy (GDMT) optimization. Unlike diuretics or other GDMT, early dapagliflozin initiation could achieve both AHF goals. OBJECTIVES: The authors aimed to assess the diuretic efficacy and safety of early dapagliflozin initiation in AHF. METHODS: In a multicenter, open-label study, 240 patients were randomized within 24 hours of hospital presentation for hypervolemic AHF to dapagliflozin 10 mg once daily or structured usual care with protocolized diuretic titration until day 5 or hospital discharge. The primary outcome, diuretic efficiency expressed as cumulative weight change per cumulative loop diuretic dose, was compared across treatment assignment using a proportional odds model adjusted for baseline weight. Secondary and safety outcomes were adjudicated by a blinded committee. RESULTS: For diuretic efficiency, there was no difference between dapagliflozin and usual care (OR: 0.65; 95% CI: 0.41-1.02; P = 0.06). Dapagliflozin was associated with reduced loop diuretic doses (560 mg [Q1-Q3: 260-1,150 mg] vs 800 mg [Q1-Q3: 380-1,715 mg]; P = 0.006) and fewer intravenous diuretic up-titrations (P ≤ 0.05) to achieve equivalent weight loss as usual care. Early dapagliflozin initiation did not increase diabetic, renal, or cardiovascular safety events. Dapagliflozin was associated with improved median 24-hour natriuresis (P = 0.03) and urine output (P = 0.005), expediting hospital discharge over the study period. CONCLUSIONS: Early dapagliflozin during AHF hospitalization is safe and fulfills a component of GDMT optimization. Dapagliflozin was not associated with a statistically significant reduction in weight-based diuretic efficiency but was associated with evidence for enhanced diuresis among patients with AHF.

Outflow graft obstruction (OGO) is a potentially fatal complication of left ventricular assist device (LVAD) implantation. Common causes include graft kinking, luminal stenosis, and graft thrombosis. We describe a case of a 51-year-old female who presented with acute LVAD failure and cardiogenic shock. Initial imaging revealed OGO without luminal stenosis following which she was she was empirically treated for graft thrombosis with anticoagulation and catheter-based thrombolytic therapy with no success. Further imaging in the catheterization laboratory revealed a potential neointimal flap dissection acting as a one-way valve. A stent was successfully placed across the outflow graft with immediate resolution of cardiogenic shock. The case emphasizes the importance of including neointimal flap as a differential for OGO in acute LVAD failure, especially in cases where thrombolytic therapy fails to correct hemodynamic compromise.

Chronic kidney disease (CKD) and hemodialysis increase the risk of sudden cardiac death (SCD) in heart failure (HF); however, national trends in utilization and outcomes of implantable cardioverter-defibrillator (ICD) in this population remain unknown. We sought to evaluate the utilization and outcomes of ICD therapy in HF patients with CKD and end-stage renal disease (ESRD) using the National Inpatient Sample from 2009 to 2018. Hospitalizations with a discharge diagnosis of systolic HF and ICD implantation were identified and stratified by stages of kidney disease. A total of 281,219 systolic HF hospitalizations who underwent ICD implantation were included. A significant decrease in inpatient ICD implantation was observed over the past decade (3.7% in 2009 to 1.1% in 2018) regardless of renal impairment. In-hospital mortality was highest in ESRD, followed by CKD compared with patients with no CKD. Length of hospital stay and hospitalization costs were also significantly higher in patients with CKD and ESRD. The overall utilization of inpatient ICD implantation has decreased in systolic HF patients and inpatient ICD placement in CKD is associated with an increased risk of mortality and adverse clinical outcomes. This indicates that patients with renal impairment and HF represent a sicker cohort than the general HF population.

COVID-19 infection manifests as a spectrum of respiratory and vascular complications, including acute respiratory distress syndrome (ARDS) and pulmonary embolism. Herein, we describe a case of a healthy young male who presented with ARDS refractory to mechanical ventilation and concomitant bilateral pulmonary emboli managed with extracorporeal membrane oxygenation (ECMO) and embolectomy. The embolectomy and initial veno-venous ECMO configuration failed to correct the patient's hypoxemia despite maximal flows. This was thought to be due to a high-output state secondary to vasodilatory shock preventing adequate drainage from the existing single drainage ECMO cannulation, following which a second venous cannula was placed to form a unique veno-veno-venous ECMO circuit that resolved the persistent hypoxemia. The case underscores the importance of identifying embolic events and vasodilatory shock in COVID-19 patients, both of which need to be addressed simultaneously to avoid worsening right ventricular failure (via both mechanical and hypoxia-driven pathways) and the resulting veno-arterial ECMO along with its associated complications.
