RESUMEN
Background: Despite an association between operator volumes and procedural success, there remains an incomplete understanding of the contemporary utilization and procedural volumes for mitral valve transcatheter edge-to-edge repair (MTEER). We aimed to identify annual operator procedural volumes, temporal trends, and geographic variability for MTEER among Medicare patients in the United States (US). Methods: We queried the National Medicare Provider Utilization and Payment Database for a CPT code (33418) specific for MitraClip device from 2015 through 2019. We analyzed annual operator procedural volumes and incidence and identified longitudinal and geographic trends in MTEER utilization. Results: From 2015 through 2019, a total of 27,034 MTEER procedures were performed among Medicare patients in the US. The nationwide incidence increased from 6.2 per 100,000 patients in 2015 to 23.8 per 100,000 patients in 2019, a 283% increase over the study period (Ptrend < 0.001). The incidence of MTEER by state varied by nearly 900% (range 5.5 to 54.9 per 100,000 person-years). In 2019, the mean annual MTEER operator annual volume was 9.1 MTEER procedures and had grown from 6.2 per year in 2015. Conclusions: In this nationwide study of Medicare beneficiaries in the United States, we identified a significant and sustained increase in the utilization of MTEER devices and operators and growth in annual procedural volumes from 2015 through 2019 with considerable variability in utilization by state. Further studies are needed to understand the clinical impact of variability in utilization and the optimal procedural volumes to ensure high efficacy outcomes and maintain critical access to MTEER therapies.

Left ventricular (LV) unloading is an important concept in patients undergoing peripheral venoarterial extracorporeal membrane oxygenation (VA-ECMO). We present a case of a 32-year-old male in acute cardiorespiratory collapse due to coronavirus disease (COVID-19) who underwent VA-ECMO cannulation in the setting of cardiogenic shock and acute respiratory distress syndrome. Due to inability to utilize percutaneous LV assist device (pLVAD) for LV unloading due to small end diastolic dimension, alternative strategies were explored. A traditionally utilized right ventricular support device, the ProTek Duo (TandemLife, Pittsburgh, PA), was utilized to drain the pulmonary artery, leading to improvement in parameters for cardiogenic shock. To our knowledge, this is the first case in which a ProTek Duo has been utilized in conjunction with VA-ECMO to provide LV unloading in support of a patient in cardiogenic shock. This method can be employed in future challenging situations where pLVAD is not feasible.

A 48-year-old woman with a past medical history of migraines and hyperlipidemia presented due to severe retrosternal chest pain with no other associated signs or symptoms. The patient was hemodynamically stable and was found to have an elevated troponin with electrocardiogram showing no ischemic changes. Computed tomography of the coronary arteries showed a left dominant system with dissection extending from the mid-to-distal left anterior descending (LAD) artery. The patient was subsequently discharged on medical therapy but returned 3 days later due to worsening chest pain. Electrocardiogram revealed inferior and anteroseptal ST segment changes with peak troponin of 14.9 ng/ml (reference range <0.80 ng/ml). Coronavirus disease 2019 (COVID-19) nasopharyngeal swab was performed prior to urgent coronary angiogram. Coronary angiogram was performed with full personal protective equipment for respiratory and droplet precautions due to pending COVID-19 testing results. Angiogram revealed spontaneous coronary artery dissection (SCAD) extending from the ostium of the LAD to the distal vessel. COVID-19 testing returned positive while in intensive care unit. The patient was not a percutaneous coronary intervention candidate due to the extent of the dissection and was not a surgical candidate due to a lack of graftable target and medical management was continued. To our knowledge, this case is the first in which SCAD has been reported in the LAD in a patient with COVID-19 with no other symptoms of respiratory illness or symptoms classically associated with the novel coronavirus. SCAD should be considered on the differential as one of the various cardiac manifestations of COVID-19 infection.

A 69-year-old woman with diabetes was found to have multi-vessel coronary artery disease and underwent 5-vessel coronary artery bypass grafting. Patient had persistent cardiogenic shock postoperatively despite intra-aortic balloon pump and escalating pressor requirements. Electrocardiogram showed new ischemic changes and the patient was urgently taken to the catheterization lab for coronary angiography and placement of an Impella CP for higher degree of hemodynamic support via the left femoral artery. Due to limitations in vascular access the Impella CP sheath was utilized for vascular access for diagnostic angiography and coronary intervention concurrently with ongoing Impella CP support. The first obtuse marginal had severe proximal disease and was treated with percutaneous coronary intervention (PCI) with a drug eluting stent. To our knowledge, this case is the first in which successful diagnostic angiography as well as multi-vessel PCI was performed via an Impella sheath while concurrently using the percutaneous mechanical circulatory support system of the Impella CP. Multiple guide catheters and a pigtail catheter were successfully passed via the Impella CP sheath to perform PCI. This novel method of vascular access could be an important tool to use in high-risk patients with limitations in access sites and decrease potential bleeding complications by limiting the number of arterial punctures.

Among patients who have undergone percutaneous coronary intervention (PCI), the use of dual antiplatelet therapy (DAPT) is associated with increased risk of bleeding, but decreased stent thrombosis and myocardial infarction unrelated to the stent. As PCI techniques and devices have progressed, the optimal duration of DAPT has come into question. We identified all randomized controlled trials (RCTs) of patients undergoing PCI, who received one or more drug eluting stents (DES) for stable coronary artery disease (CAD) or acute coronary syndrome (ACS), and randomized to short (1-3 months) versus standard duration DAPT. The prespecified primary outcome was major adverse cardiovascular events (MACE). Important secondary outcomes were net adverse clinical events (NACE) defined as MACE and major bleeding; any bleeding; major bleeding; all-cause death; cardiovascular death. We calculated hazard ratios (HR) and 95% confidence intervals (CI) using random-effects model. Analysis included 7 RCTs, comprising 35,857 patients and 53,321 patient-years of follow-up. The mean (SD) age of patients was 64.4 (10.6) years, 49.6% of patients presented with ACS, and 25.5% were female. There was no difference between short and standard-length DAPT in regards to MACE (HR = 0.93; 95% CI 0.84-1.03; p = 0.19), NACE (HR = 0.93; 95% CI 0.85-1.02; p = 0.12), all-cause death (HR = 0.92; 95% CI 0.80-1.05; p = 0.21), or cardiovascular death (HR = 0.85; 95% CI 0.64-1.13; p = 0.26). However, short-term DAPT was associated with significantly reduced major bleeding events (HR = 0.67; 95% CI 0.47-0.95; p = 0.03) and any bleeding event (HR = 0.63; 95% CI 0.44-0.90; p = 0.01) compared with standard-length DAPT. Among patients undergoing PCI for CAD, the use of short-term DAPT (1-3 months) followed by single antiplatelet therapy was associated with a lower incidence of clinically relevant bleeding events, but with similar risk of MACE, all-cause death, and cardiovascular death compared with standard duration DAPT.

Mitral valve stenosis remains highly prevalent among the US population although with dramatically shifting demographics. The significance of rheumatic mitral disease in developing nations persists, despite improvements in preventative measures and early detection, and its presence in developed countries is still evident as observed through international migration. In addition, the substantial growth in the aging population with a heightened occurrence of concurrent cardiovascular risk factors is leading to an increased prevalence of chronic calcific degeneration and degeneration of previously repaired or replaced valves. This article aims to review various transcatheter therapies in the treatment of mitral valve stenosis.

Background: Intravascular lithotripsy (IVL) safely and effectively modifies calcified coronary lesions during percutaneous coronary interventions (PCI). Data regarding its utility in modifying calcified left main coronary artery (LMCA) disease are limited. This study aimed to evaluate short-term outcomes of IVL-assisted LMCA PCI. Methods: This retrospective multicenter all-comers study analyzed patients who underwent intravascular imaging-guided, IVL-assisted PCI for calcified LMCA disease. Clinical and procedural characteristics were obtained, including intravascular imaging measurements. Technical success was defined as successful stent deployment with <30% residual diameter stenosis. Major adverse cardiac events (MACE) was a composite of all-cause death, myocardial infarction, and target vessel revascularization evaluated immediately postprocedure and at 30-day follow-up. Results: Among 184 patients treated at 7 centers from 2019-2023, IVL-assisted LMCA PCI achieved 99.4% technical success. Calcium fracture was identified in 136/165 cases (82.4%) on post-IVL imaging. Pretreatment minimal luminal area increased significantly compared to post-PCI minimal stent area (MSA) (4.1 ± 1.3 to 9.3 ± 2.5 mm2, respectively; P < .001). There was a direct correlation between IVL balloon size and the final MSA (P = .002). In-hospital MACE was 4.4% and 30-day MACE was 8.8%. In multivariate logistic regression, presentation with troponin-positive myocardial infarction was the sole predictor of 30-day MACE. Conclusions: IVL-assisted PCI for calcified LMCA lesions was safe and resulted in high technical success rates, confirming its utility as an effective treatment in this challenging lesion subset.
RESUMEN
Background: There is an incomplete understanding of the predictors of morbidity and mortality in patients with severe tricuspid regurgitation (TR). This study sought to identify key risk factors for all-cause mortality and heart failure (HF) hospitalization among patients with severe TR. Methods: Patients with severe TR were identified from 2 centers, Oregon Health & Science University and Abrazo Health, from January 01, 2016 to December 31, 2018. Patients with any concomitant severe valvular diseases or prior valvular intervention were excluded. Multivariable regression was utilized to identify demographic, clinical, and echocardiographic variables independently associated with all-cause mortality or HF hospitalization. Results: 435 patients with severe TR were followed for a median of 2.8 years. The mean age of the population was 66.9 ± 18.5 years and 58% were female. All-cause mortality was identified in 20.5% of the population. Of the cohort, 35.4% of patients were hospitalized for HF. Isolated tricuspid valve intervention was performed in 2.5% of patients. Independent predictors of all-cause mortality included history of solid tumor (odds ratio [OR] 6.6, 95% confidence interval [CI] 2.1-19.1, p = 0.001), history of peripheral artery disease (OR 3.5, 95% CI 1.2-9.4, p = 0.013), and elevated international normalized ratio in the absence of anticoagulation (OR 1.9, 95% CI 1.2-3.2, p = 0.008). Predictors of HF hospitalization included history of diabetes mellitus (OR 2.2, 95% CI 1.1-4.0, p = 0.014) and history of reduced left ventricular ejection fraction (OR 5.7, 95% CI 2.9-11.7, p < 0.0001). Conclusions: Severe untreated TR is associated with high mortality and frequent HF hospitalizations. Understanding predictors of these outcomes is important to identify patients who may benefit from early tricuspid valve intervention to help improve outcomes in this patient population.
RESUMEN
Chest radiation therapy (XRT) has been associated with a higher rate of mortality following surgical aortic valve replacement. We performed a single-center retrospective analysis of patients with severe AS who underwent TAVI from January 1 2012 to July 31 2020 comparing patients with and without XRT. A total of 915 patients met inclusion criteria, with a total of 50 patients found to have a history of XRT. At a mean follow-up of 2.4 years, unadjusted and propensity score matching analysis demonstrated no differences in mortality, heart failure or bleeding-related hospitalization, overall stroke, and 30-day pacemaker implantation in patients with and without XRT.

Platelet aggregation and thrombus formation represent the basic mechanism for clinical, electrocardiographic, and biomarker changes consistent with acute coronary syndrome. Various oral and intravenous formulations of platelet function inhibitors have been developed to help decrease platelet aggregation due to acute atherosclerotic plaque rupture. In this article, we review the various mechanisms, pharmacokinetics/pharmacodynamics, and the key clinical trials related to the platelet inhibitors that form the basis for current recommendations of their use in the ST elevation myocardial infarction guidelines by the American College of Cardiology/American Heart Association.

BACKGROUND: Mitral regurgitation is the most common form of valvular heart disease worldwide, however, there is an incomplete understanding of predictors of mortality in this population. This study sought to identify risk factors of mortality in a real-world population with mitral regurgitation. METHODS: All patients with moderate or severe mitral regurgitation were identified at a single center from January 1, 2016 to August 31, 2017. Multivariate regression was performed to evaluate variables independently associated with all-cause mortality. RESULTS: A total of 490 patients with moderate (76.3%) or severe (23.7%) mitral regurgitation due to primary (20.8%) or secondary (79.2%) etiology were identified. The mean age was 66.7 years; 50% were male. At a median follow-up of 3.1 years, the incidence of all-cause mortality was 30.1%, heart failure hospitalization 23.1%, and mitral valve intervention 11.6%. Of 117 variables, multivariate analysis demonstrated 5 that were independently predictive of mortality: baseline creatinine (hazard ratio [HR] 1.2; 95% CI, 1.0-1.3; P = .02), right atrial pressure by echocardiogram (HR 1.3; 95% CI, 1.07-1.55; P = .008), hemoglobin (HR 0.65; 95% CI, 0.52-0.83; P = .001), hospitalization for heart failure (HR 1.6; 95% CI, 1.1-2.4; P = .015), and mitral valve intervention (HR 0.40; 95% CI, 0.16-0.83; P = .049). CONCLUSION: In this retrospective, pragmatic analysis of patients with moderate or severe mitral regurgitation, admission for heart failure exacerbation, elevated right atrial pressure, renal dysfunction, anemia, and lack of mitral valve intervention were independently associated with increased risk of all-cause mortality. Whether these risk factors may better identify select patients who may benefit from more intensive monitoring or earlier intervention should be considered in future studies.

BACKGROUND: Statins have anti-inflammatory and immunomodulatory effects that may reduce the severity of coronavirus disease 2019 (COVID-19), in which organ dysfunction is mediated by severe inflammation. Large studies with diverse populations evaluating statin use and outcomes in COVID-19 are lacking. METHODS AND RESULTS: We used data from 10,541 patients hospitalized with COVID-19 through September 2020 at 104 US hospitals enrolled in the American Heart Association's COVID-19 Cardiovascular Disease (CVD) Registry to evaluate the associations between statin use and outcomes. Prior to admission, 42% of subjects (n = 4,449) used statins (7% on statins alone, 35% on statins plus anti-hypertensives). Death (or discharge to hospice) occurred in 2,212 subjects (21%). Outpatient use of statins, either alone or with anti-hypertensives, was associated with a reduced risk of death (adjusted odds ratio [aOR] 0.59, 95% CI 0.50-0.69), adjusting for demographic characteristics, insurance status, hospital site, and concurrent medications by logistic regression. In propensity-matched analyses, use of statins and/or anti-hypertensives was associated with a reduced risk of death among those with a history of CVD and/or hypertension (aOR 0.68, 95% CI 0.58-0.81). An observed 16% reduction in odds of death among those without CVD and/or hypertension was not statistically significant. CONCLUSIONS: Patients taking statins prior to hospitalization for COVID-19 had substantially lower odds of death, primarily among individuals with a history of CVD and/or hypertension. These observations support the continuation and aggressive initiation of statin and anti-hypertensive therapies among patients at risk for COVID-19, if these treatments are indicated based upon underlying medical conditions.

Intracardiac thrombi are not uncommon, but right atrial (RA) thrombi are exceedingly rare. Thrombi can lead to a variety of complications, such as systemic and pulmonary embolism. While various imaging modalities are helpful in the diagnosis, an echocardiogram is the most commonly used one. Principle management of the condition involves anticoagulation. However, management can vary among different patient groups, depending on the location and size of thrombi. We present a case of an RA thrombosis due to dilation of the atria and trauma from an infected central venous catheter in a patient with a past medical history of pulmonary artery hypertension (PAH).
RESUMEN
BACKGROUND: We aimed to conduct this study with the goal of further clarifying the role of sodium-glucose cotransporter-2 inhibitors (SGLT2i) in patients with preexisting heart failure with reduced ejection fraction with or without diabetes and to leverage increased sample size and power to evaluate clinically important secondary safety and efficacy outcomes. METHODS: This meta-analysis was completed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The primary outcome was a composite of cardiovascular death or heart failure hospitalization. Secondary outcomes included the individual components of the primary outcome; major adverse cardiovascular events (defined as a composite of cardiovascular death, myocardial infarction, stroke), any death, myocardial infarction, or stroke, along with adverse events such as volume depletion, acute kidney injury, adverse events leading to drug discontinuation, amputation, and severe hypoglycemia. Other outcomes included the Kansas City Cardiomyopathy Questionnaire (KCCQ) total symptom score and changes in N-terminal pro-hormone BNP (NT-proBNP). Pooled hazard ratios (HRs) and 95% confidence intervals (CIs) for dichotomous variables and weighted difference (MD) and 95% CI for continuous variables. RESULTS: Compared with placebo, SGLT2i use was associated with a significant reduction of cardiovascular death or heart failure hospitalization (HR = 0.74; 95% CI = 0.66-0.82; P <0.01), heart failure hospitalization (HR = 0.69; 95% CI = 0.57-0.84; P <0.01), cardiovascular death (HR = 0.79; 95% CI = 0.68-0.92; P <0.01), and any death (HR = 0.80; 95% CI = 0.70-0.92; P <0.01). CONCLUSIONS: SGLT2i was associated with a decreased risk of clinically relevant cardiovascular death, heart failure hospitalization, and heart failure symptoms with similar rates of adverse events.

BACKGROUND: The purpose of this study was to identify predictors of mortality and potentially modifiable factors related to arrhythmias in patients that undergo transcatheter aortic valve replacement (TAVR). Patients that undergo TAVR are at risk for complete heart block requiring pacemaker implant. Additionally, other arrhythmias, specifically atrial fibrillation (AF), are common in this population. It is unclear how arrhythmias and their management contribute to mortality risk. METHODS: The study analyzed 176 patients who underwent TAVR at a single center. Factors associated with pacemaker implantation within 30 days were analyzed by logistic regression. Factors associated with mortality were analyzed by Kaplan-Meier and Cox regression analyses. RESULTS: Mean age was 80 ± 8.5 years. AF was present in 69 patients, and 39 received anticoagulation. Post-TAVR, a pacemaker was implanted in 25 patients within 30 days. Over a follow up of 566 ± 496 days, 49 patients died. In multivariable analysis, right bundle branch block remained significant (odds ratio 4.212, P = 0.012) for pacemaker implant within 30 days. The AF (hazard ratio [HR] 3.905, P = 0.001), albumin level (HR 0.316, P = 0.034), and diabetes (HR 2.323, P = 0.027) were predictors of death in a multivariate analysis, while pacemaker implant within 30 days was not. Patients with AF who were anticoagulated had improved survival in a stratified Kaplan-Meier analysis compared with those who were not anticoagulated (P = 0.0001). CONCLUSION: AF, diabetes, and low albumin levels are independently associated with mortality after TAVR. In particular, patients with AF who are not anticoagulated are at highest risk for death. Efforts to identify AF and consider anticoagulation should be emphasized.

An 82-year-old woman with severe respiratory distress and limitations in functional status was found to have severe mitral valve stenosis with annular calcification and referred for transcatheter mitral valve replacement. Prophylactic alcohol septal ablation was used pre-procedurally to minimize mortality risk due to obstruction of the left ventricular outflow tract. (Level of Difficulty: Intermediate.).
RESUMEN
BACKGROUND: Out of hospital cardiac arrest management of patients with non-ST myocardial infarction per current American Heart Association and European Resuscitation Council guidelines leave the decision in regard to early angiography up to the physician operators. Guidelines are clear on the positive impact of early intervention on survival and improvement on left ventricular function in patients presenting with cardiac arrest and ST elevation myocardial infarction on electrocardiogram. This review aims to analyze the data that current guidelines are based upon in regards to out of hospital cardiac arrest with electrocardiogram findings of non-ST elevation myocardial infarction as well as review of other clinical trials that support early angiography and reperfusion strategies. CONCLUSION: Analysis of current literature shows that early coronary evaluation in patients with no finding of ST elevation on ECG can help improve survival in patients suffering out of hospital cardiac arrest.
