RESUMO
Background: There has been a significant increase in the utilization of venoarterial extracorporeal membrane oxygenation (VA-ECMO) in recent years. Cardiothoracic surgery teams have historically led VA-ECMO care teams, with little data available on alternative care models. Methods: We performed a retrospective review of a cardiovascular medicine inclusive VA-ECMO service, analyzing patients treated with peripheral VA-ECMO at a large quaternary care center from 2018 to 2022. The primary outcome was death while on VA-ECMO or within 24 hours of decannulation. Univariate and multivariate analyses were used to identify predictors of the primary outcome. Results: Two hundred forty-four patients were included in the analysis (median age 61 years; 28.7% female), of whom 91.8% were cannulated by interventional cardiologists, and 84.4% were managed by a cardiology service comprised of interventional cardiologists, cardiac intensivists or advanced heart failure cardiologists. Indications for VA-ECMO included acute myocardial infarction (34.8%), decompensated heart failure (30.3%), and refractory cardiac arrest (10.2%). VA-ECMO was utilized during cardiopulmonary resuscitation in 26.6% of cases, 48% of which were peri-procedural arrest. Of the patients, 46% survived to decannulation, the majority of whom were decannulated percutaneously in the cardiac catheterization laboratory. There was no difference in survival following cannulation by a cardiac surgeon vs interventional cardiologist (50% vs 45%; P = .90). Complications included arterial injury (3.7%), compartment syndrome (4.1%), cannulation site infection (1.2%), stroke (14.8%), acute kidney injury (52.5%), access site bleeding (16%) and need for blood transfusion (83.2%). Elevated baseline lactate (odds ratio [OR], 1.13 per unit increase) and sequential organ failure assessment score (OR, 1.27 per unit increase) were independently associated with the primary outcome. Conversely, an elevated baseline survival after VA ECMO score (OR, 0.92 per unit increase) and 8-hour serum lactate clearance (OR, 0.98 per % increase) were independently associated with survival. Conclusions: The use of a cardiovascular medicine inclusive ECMO service is feasible and may be practical in select centers as indications for VA-ECMO expand.
RESUMO
INTRODUCTION: Patients with a small aortic annulus (SAA) undergoing aortic valve replacement are at increased risk of patient-prosthesis mismatch (PPM), which adversely affects outcomes. Transcatheter aortic valve replacement (TAVR) has shown promise in mitigating PPM compared to surgical aortic valve replacement (SAVR). METHODS: We conducted a systematic review and meta-analysis following PRISMA guidelines to compare clinical outcomes, mortality, and PPM between SAA patients undergoing TAVR and SAVR. Eligible studies were identified through comprehensive literature searches and assessed for quality and relevance. RESULTS: Nine studies with a total of 2476 patients were included. There was no significant difference in 30-day Mortality between TAVR vs SAVR groups (OR = 0.65, 95% CI [ 0.09-4.61], P = 0.22). There was no difference between both groups regarding myocardial infarction at 30 days (OR = 0.63, 95% CI [0.1-3.89], P = 0.62). TAVR was associated with a significantly lower 30-day major bleeding and 2-year major bleeding, Pooled studies were homogeneous (OR = 0.44, 95% CI [0.31-0.64], P < 0.01, I2 = 0, P = 0.89), (OR = 0.4 ,95% CI [0.21-0.77], P = 0.03, I2 = 0%, P = 0.62) respectively. TAVR was associated with a lower rate of moderate PPM (OR = 0.6, 95% CI [ 0.44-0.84], p value = 0.01, i2 = 0%, p value = 0.44). The overall effect estimate did not favor any of the two groups regarding short-term Mild AR (OR = 5.44, 95% CI [1.02-28.91], P = 0.05) and Moderate/severe AR (OR = 4.08, 95% CI [ 0.79-21.02], P = 0.08, I2 = 0%, P = 0.59). CONCLUSION: Our findings suggest that both TAVR and SAVR are viable options for treating AS in patients with a small aortic annulus. TAVR offers advantages in reducing PPM and major bleeding, while SAVR performs better in terms of pacemaker implantation. Future studies should focus on comparing newer generation TAVR techniques and devices with SAVR. Consideration of patient characteristics is crucial in selecting the optimal treatment approach for AS.

INTRODUCTION: Hypertrophic cardiomyopathy (HCM) poses unique challenges in the management of pregnant patients due to the complex interplay of physiological changes of pregnancy. Despite its relatively low prevalence among pregnant women, HCM can significantly impact maternal and fetal outcomes. This study aims to enhance understanding of pregnant patients with HCM and the associated outcomes through a nationwide analysis of patient characteristics and outcomes. METHODS: A retrospective analysis was conducted using data obtained from the Agency for Healthcare Research in Quality (AHRQ) Nationwide Inpatient Sample (NIS) database from January 2016 to December 2020. 3,599,855 pregnant patients without HCM and 187 pregnant patients with HCM were identified using International Classification of Disease (ICD) codes, and baseline characteristics, medical comorbidities, and outcomes were compared between the two groups. RESULTS: Significant differences were observed in baseline characteristics, including age distribution, racial composition, and prevalence of systemic organ disease, between pregnant women with and without HCM. Women with HCM had higher odds of experiencing maternal complications, such as acute heart failure and peripartum cardiomyopathy, as well as higher rates of fetal distress and obstetric interventions, including preterm delivery and caesarean section. CONCLUSION: Comprehensive cardiovascular assessment and risk stratification are essential in pregnant women with HCM to optimize maternal and fetal outcomes. Moreover, disparities in baseline characteristics and outcomes among black pregnant women with HCM highlight the need for a multifactorial approach to addressing pregnancy-related complications.

Up to 20 % of patients presenting with acute heart failure and cardiogenic shock have a structural etiology. Despite efforts in timely management, mortality rates remain alarmingly high, ranging from 50 % to 80 %. Surgical intervention is often the definitive treatment for structural heart disease; however, many patients are considered high risk or unsuitable candidates for such procedures. Consequently, there has been a paradigm shift towards the development of novel percutaneous management strategies and temporizing interventions. This article aims to provide a comprehensive review of the pathophysiology of valvular and structural heart conditions presenting in cardiogenic shock, focusing on the evolving landscape of mechanical circulatory support devices and other management modalities.

Background: Solid organ transplant (SOT) recipients with COVID-19 have a higher risk of mortality than those without COVID-19. However, it is unclear how SOT patient outcomes compare to the general population without SOT who contract COVID-19. Methods: We used the National Inpatient Sample from January to December 2020 to investigate inpatient outcomes seen in SOT recipients after contracting COVID-19 compared to nontransplant patients. We identified our study sample using ICD-10 CM and excluded those <18 years of age and those with dual organ transplants. Inpatient outcomes were compared in SOT and non-SOT COVID cohorts, and we further evaluated predictors of mortality in the SOT with COVID population. Results: Out of the 1,416,445 COVID-19 admissions included in the study, 8315 (0.59%) were single SOT recipients. Our analysis that adjusted for multiple baseline characteristics and comorbidities demonstrated that COVID-19 in SOT patients was associated with higher rates of acute kidney injury (adjusted odds ratio [aOR] 2.34, 95% confidence interval [CI] 1.81-3.02, P < 0.01), lower rates of acute respiratory distress syndrome (aOR 0.68, 95% CI 0.54-0.85, P < 0.01), and similar rates of cardiac arrest, pulmonary embolism, circulatory shock, cerebrovascular events, and in-hospital mortality. Age >65 was associated with mortality in SOT patients. Conclusion: In this nationally representative sample, SOT patients presenting with COVID-19 experienced similar rates of mortality compared to those without SOT. SOT patients were more likely to develop acute kidney injury. Further research is needed to understand the complex relationship between transplant patient outcomes and COVID-19.
RESUMO
INTRODUCTION: The rise in cardiovascular disease (CVD) in Sub-Saharan Africa (SSA) reflects a major shift from communicable to noncommunicable diseases as primary health challenges. Consequently, this study aims to explore the burden of CVD and associated risk factors in SSA using data from the Global Burden of Disease (GBD) database. METHODS: This study utilized data from the GBD 1990 to 2019 to examine CVD prevalence in 46 SSA countries. We employed Bayesian regression models, demographic techniques, and mortality-to-incidence ratios to analyze both prevalence and mortality rates. Additionally, disability-adjusted life years (DALYs) were computed, and various risk factors were examined using the GBD's comparative risk assessment framework. RESULTS: Between 1990 and 2019, CVD raw counts in SSA rose by 131.7 %, with a 2.1 % increase in age-standardized prevalence rates. The most prevalent conditions were ischemic heart disease, stroke, and rheumatic heart disease. During the same period, the age-standardized CVD deaths per 100,000 individuals decreased from 314 (1990) to 269 (2019), reflecting a -14.4 % decline. Age-standardized CVD DALY rates also showed a decrease from 6,755 in 1990 to 5,476 in 2019, with translates to 18.9 % reduction. By 2019, the Central African Republic, Madagascar, and Lesotho were the countries with the highest age-standardized DALY rates for all CVDs. CONCLUSIONS: The study highlights a contrasting trend in SSA's CVD landscape: a decrease in age-standardized mortality and DALYs contrasts with increasing CVD prevalence, emphasizing the need for targeted public health strategies that balance treatment advancements with intensified prevention and control measures.

Spontaneous coronary artery dissection (SCAD) is a common cause of myocardial infarction in young and middle-aged women. Patients with SCAD present rarely with hemodynamic collapse and cardiogenic shock, requiring immediate resuscitation and mechanical circulatory support. Percutaneous mechanical circulatory support may serve as a bridge to recovery, decision or heart transplantation. We present a case of a young woman with SCAD of the left main coronary artery, presenting with ST-elevation myocardial infarction, cardiac arrest and cardiogenic shock. She was stabilized emergently with Impella and early escalation with extracorporeal membrane oxygenation (ECPELLA) at a non-surgical community hospital. Despite revascularization with percutaneous coronary intervention (PCI), her left ventricular recovery was poor, and ultimately required cardiac transplantation on day 5 of her presentation.

BACKGROUND: A hemoglobin (Hb) level goal of 7-8 g/dL is a standard care threshold, prompting blood transfusion. The debate over whether acute myocardial infarction (MI) patients benefit from a more liberal transfusion strategy prompted a meta-analysis of relevant trials. METHODS: We performed a meta-analysis of randomized controlled trials (RCTs) comparing liberal and restrictive transfusion strategies in anemic MI patients. Primary outcomes were recurrent MI and death/MI, while secondary outcomes included stroke, revascularization, heart failure, and all-cause mortality. Due to the limited trials, we utilized the Paul-Mendele method with Hartung Knapp adjustment. RESULTS: Involving 2155 patients with liberal transfusion and 2170 with conservative transfusion across four RCTs, liberal transfusion did not significantly reduce MI (relative risk [RR] 0.85; 95 % CI 0.72 - 1.02, p = 0.07) or death/MI (RR 0.88; 95 % CI 0.45 - 1.71, p = 0.57). No significant differences were observed in all-cause mortality (RR 0.82; 95 % CI 0.25 - 2.68, p = 0.63), stroke (RR 0.89; 95 % CI 0.48 - 1.64, p = 0.50), revascularization (RR 0.93; 95 % CI 0.48 - 1.80, p = 0.68), or heart failure (RR 1.14; 95 % CI 0.04 - 28.84, p = 0.88). CONCLUSION: Our meta-analysis supports current medical guidelines, reinforcing the practice of limiting transfusions in acute MI patients to those with an Hb level of 7 or 8 g/dL. Liberal transfusion strategies did not show improved clinical outcomes.

INTRODUCTION: Cardiovascular disease (CVD) remains the leading cause of death globally, including the Middle East and North Africa (MENA) region. However, limited research has been conducted on the burden of CVD in this region. Our study aims to investigate the burden of CVD and related risk factors in the MENA. METHODS: We used data from the Global Burden of Disease (GBD) 2019 to examine CVD prevalence in 21 MENA countries. Prevalence and mortality were analyzed using Bayesian regression tools, demographic methods, and mortality-to-incidence ratios. Disability-adjusted life years (DALYs) were calculated, and risk factors were evaluated under the GBD's comparative risk assessment framework. RESULTS: Between 1990 and 2019, CVD raw accounts in the MENA increased by 140.9%, while age standardized prevalence slightly decreased (-1.3%). CVD raw mortality counts rose by 78.3%, but age standardized death rates fell by 28%. Ischemic heart disease remained the most prevalent condition, with higher rates in men, while women had higher rates of CVA. Age standardized DALYs decreased by 32.54%. DALY rates varied across countries and were consistently higher in males. Leading risk factors included hypertension, high LDL-C, dietary risks, and elevated BMI. The countries with the three highest DALYs in 2019 were Afghanistan, Egypt, and Yemen. CONCLUSIONS: While strides have been made in lessening the CVD burden in the MENA region, the toll on mortality and morbidity, particularly from ischemic heart disease, remains significant. Country-specific variations call for tailored interventions addressing socio-economic factors, healthcare infrastructure, and political stability.

The left anterior descending artery (LAD) subtends a large myocardial territory. The outcomes of LAD chronic total occlusion (CTO) percutaneous coronary intervention (PCI) have received limited study. We performed a retrospective analysis of all patients who underwent LAD CTO PCI at a high-volume single center. Outcomes included in-hospital and long-term major adverse cardiovascular events (MACEs) and changes in left ventricular ejection fraction (LVEF). We performed a subgroup analysis of patients with ischemic cardiomyopathy, defined as an LVEF of 40% or less. From December 2014 to February 2021, 237 patients underwent LAD CTO PCI. The technical success rate was 97.4%, and the in-hospital MACE rate was 5.4%, A landmark analysis after hospital discharge showed an overall survival of 92% and 85% MACE-free survival at 2 years. There was no difference in overall survival or MACE-free survival between those who had ischemic cardiomyopathy versus those who did not. In patients with ischemic cardiomyopathy, LAD CTO PCI was associated with significant improvement in LVEF (10.9% at 9 months), which was further pronounced when these patients had a proximal LAD CTO and were on optimal medical therapy (14% at 6 months). In a single high-volume center, LAD CTO PCI was associated with 92% overall survival at 2 years, with no difference in survival between patients with or without ischemic cardiomyopathy. LAD CTO PCI was associated with an absolute 10% increase in LVEF at 9 months in patients with ischemic cardiomyopathy.

Left ventricular (LV) unloading has been associated with improved survival in patients treated with venoarterial extracorporeal membrane oxygenation. This case describes a patient with a COVID-19 infection who subsequently developed non-ischemic cardiomyopathy with an LV ejection fraction of 10% to 15% (baseline echocardiography). He did poorly in the outpatient setting and was admitted to an outside hospital with heart failure symptoms and was subsequently transferred to our hospital for escalation of care and consideration of advanced heart failure therapies. This clinical image and related video series help to visually demonstrate the effect of LV unloading in a 30-year-old male with a history of COVID-19 myocarditis.

BACKGROUND: Mechanical circulatory support (MCS) devices are increasingly used for hemodynamic support in cardiogenic shock or high-risk percutaneous coronary interventions. Vascular complications remain a major source of morbidity and mortality despite technological advances with percutaneous techniques. Little is known about the rates and predictors of vascular complications with large-bore access MCS in the contemporary era. METHODS: The study cohort was derived from National Inpatient Sample using data from 2015 to 2019 for cardiac hospitalizations with the use of: intra-aortic balloon pump (IABP) Impella, and/or extracorporeal membrane oxygenation (ECMO). The rates of vascular complications and in-hospital outcomes were analyzed using multivariable logistic regression. RESULTS: Of 221,700 hospitalizations with MCS use, the majority had only IABP (68%). The rates of vascular complications were greatest with ECMO (15.8%) when compared with IABP (3.0%) and Impella (5.6%). Among patients with vascular complications, in-hospital mortality was higher with ECMO (56.3%) when compared with IABP (26.2%) and Impella (33.8%). Peripheral arterial disease (PAD) was the strongest predictor of vascular complications, with 10 times higher odds when present (adjusted odds ratio [aOR] 10.96, p < 0.001). In risk-adjusted models, when compared with IABP, the use of Impella (aOR: 1.73, p < 0.001), ECMO (aOR: 5.35, p < 0.001), or a combination of MCS devices (aOR: 3.47, p < 0.001) was associated with higher odds of vascular complications. CONCLUSIONS: In contemporary practice, the use of MCS is associated with significant vascular complications and in-hospital mortality. Predictors of vascular complications include larger arteriotomy size, female gender, and peripheral arterial disease. Vascular access management remains essential to prevent major complications.

PURPOSE OF REVIEW: The COVID-19 pandemic has created unprecedented challenges globally, with significant strain on the healthcare system in the United States and worldwide. In this article, we review the impact of COVID-19 on percutaneous coronary interventions and structural heart disease practices, as well as the impact of the pandemic on related clinical research and trials. We also discuss the consensus recommendations from the scientific societies and suggest potential solutions and strategies to overcome some of these challenges. FINDINGS: With the limited resources and significant burden on the healthcare system during the pandemic, changes have evolved in practice to provide care to the highest risk patients while minimizing unnecessary exposure during elective surgical or transcatheter procedures. The COVID-19 crisis has significantly impacted the management of patients with acute coronary syndromes, chronic coronary syndromes, and structural heart disease.

BACKGROUND: To describe the national trends and outcomes of contemporary thrombectomy use for primary percutaneous coronary intervention (PCI) from 2016 to 2018. METHODS: We queried the Nationwide Readmission Database (NRD) from January 2016 to December 2018 to identify patients who underwent primary PCI and thrombectomy. We conducted a multivariate regression analysis to identify variables associated with in-hospital mortality and stroke in patients undergoing primary PCI and those who underwent thrombectomy. RESULTS: We identified 409,910 total hospitalizations who underwent primary PCI. Thrombectomy was used in 62,446 records (15.2%) with no change in the trend over the study period (p trend = 0.52). Thrombectomy was more utilized in patients who had more cardiogenic shock and use of mechanical circulatory devices. The overall incidence of in-hospital mortality and stroke were 5.6% and 1.1%, respectively. The incidence of in-hospital mortality (6.7% vs. 5.4%, p < 0.001) and strokes (1.3% vs. 1.0%, p < 0.001) were higher in the thrombectomy group. On multivariable regression analysis adjusting for high-risk features, thrombectomy was not independently associated with in-hospital mortality [1.036, 95% CI (0.993-1.080), p = 0.100], but was associated with a higher risk of stroke [OR 1.186, 95% CI (1.097-1.283), p < 0.001]. CONCLUSION: During primary PCI, thrombectomy was used in 1 of 6 cases, and its use has been stable over 2016-2018. The use of thrombectomy was associated with a higher risk of stroke, but not in-hospital death.

Percutaneous ventricular assist devices (pVAD) are frequently utilized in high-risk percutaneous coronary intervention (HR-PCI) to provide hemodynamic support in patients with complex cardiovascular disease and/or multiple comorbidities who are poor candidates for surgical revascularization. Using the National Inpatient Sample we identified pVAD-assisted PCI (excluding intra-aortic balloon pump) in patients without cardiogenic shock from January 2008 to December 2018. We evaluated the trends in patient and procedural characteristics, and complication rates across the 11-year study period. A total of 26,661 pVAD-PCI was performed. From 2008 to 2018 there has was a 27-fold increase in the number of pVAD-PCIs performed annually. There has also been an increase in the proportion of procedures performed in small to medium sized hospitals. The use of atherectomy, image-guided PCI, FFR/iFR, drug-eluting stents, and multi-vessel intervention has significantly increased. Patients undergoing pVAD-PCI had a higher burden of comorbidities, without a significant difference in mortality over time. There were decreased rates of acute stroke and blood transfusions over time, while vascular complications and acute kidney injury (AKI) requiring dialysis remained mostly unchanged. In conclusion, the use of pVAD for HR-PCI has increased significantly, along with adjunctive PCI techniques such as atherectomy, intravascular imaging, and physiologic lesion assessment. With increasing use of this device, there appeared to be lower rates of peri-procedural stroke, and blood transfusions. Despite a higher burden of comorbidities, adjusted mortality remained stable over time.

BACKGROUND: Debulking and ablative techniques are sometimes used for the treatment of in-stent restenosis (ISR) secondary to resistant stent under-expansion (SU). The safety and effectiveness of orbital atherectomy (OA) in this cohort of patients has not been reported. METHODS: We retrospectively evaluated consecutive patients treated with OA for ISR secondary to balloon undilatable SU at two academic tertiary care centers between October 2016 and June 2019. Angiographic or intravascular imaging identified SU. Technical success was defined as residual 0% stenosis with TIMI III flow. RESULTS: A total of 41 patients were included in the study. Patients had an average age of 65 ± 12 years; 73% male, 61% diabetic, 41% with prior coronary artery bypass grafting, 61% with a prior incident of ISR, 51% presented with stable angina, 17% unstable angina, and 32% non-ST elevation myocardial infarction (MI). Implantation of the under-expanded stents occurred between 2 months and 22 years prior to the index procedure. A total of 27% of patients had multiple layers of stents in the target lesion and 32% of patients had in-stent chronic total occlusion. Technical success was achieved in 40 (98%) patients. There were 2 (5%) major adverse cardiovascular events; both of them were periprocedural MI from the no-reflow phenomenon. There were 2 (5%) Ellis type II coronary perforations that required no intervention. CONCLUSIONS: OA can be effectively performed as an adjunctive tool in the treatment of ISR with balloon undilatable SU. The use of OA for SU is not approved by the U.S. Food and Drug Administration and is "off label" and caution must be used to limit any device/stent interaction.
