BACKGROUND: Catheter ablation is an effective treatment for ventricular arrhythmia (VA) in ischemic cardiomyopathy (ICM). However, results in non-ICM (NICM) patients are not satisfactory, and studies comparing differences between NICM and ICM are limited. We conducted a meta-analysis of procedural characteristics and long-term outcomes of catheter ablation for VA, comparing results between ICM and NICM.

METHODS: Studies in the PubMed, EMBASE, and Cochrane databases were systematically reviewed. Four studies reporting comparison of catheter ablation of VA between ICM and NICM were examined. The Newcastle-Ottawa Scale was used to appraise study quality. A random-effects model with inverse variance method was used …

Mitral Valve Repair Complicated By Left Circumflex Coronary Artery Occlusion: The Vital Role Of The Anesthesiologist, Andres Bacigalupo Landa, Jason Hoyos, Jayanand D'Mello

Faculty, Staff and Students Publications

The anatomical relationship between the mitral valve and the left circumflex coronary artery places this vessel at risk for occlusion during mitral valve repair or replacement. In view of the potential high morbidity and mortality of this complication, the anesthesiologist has a vital role in its prompt diagnosis. We present the case of a 47-year-old man who underwent a minimally invasive mitral valve repair, which was complicated by left circumflex coronary artery occlusion.

Combined Oxidative Phosphorylation Deficiency 23 (COXPD23) caused by mutations in GTPBP3 gene is a rare mitochondrial disease, and this disorder identified from the Chinese population has not been described thus far. Here, we report a case series of three patients with COXPD23 caused by GTPBP3 mutations, from a severe to a mild phenotype. The main clinical features of these patients include lactic acidosis, myocardial damage, and neurologic symptoms. Whole genome sequencing and targeted panels of candidate human mitochondrial genome revealed that patient 1 was a compound heterozygote with novel mutations c.413C > T (p. A138V) and c.509_510del (p. E170Gfs∗42) in GTPBP3 …


Trace Element Concentrations In Blood And Scute Tissues From Wild And Captive Hawaiian Green Sea Turtles (Chelonia Mydas), Katherine R Shaw, Jennifer M Lynch, George H Balazs, T Todd Jones, Jeff Pawloski, Marc R Rice, Amanda D French, Jing Liu, George P Cobb, David M Klein Jan 2021

Sea turtles are exposed to trace elements through water, sediment, and food. Exposure to these elements has been shown to decrease immune function, impair growth, and decrease reproductive output in wildlife. This study compares trace element concentrations in green turtles in captivity at Sea Life Park Hawaii (n = 6) to wild green turtles in Kapoho Bay, HI (n = 5 to 7). Blood and scute samples were collected and analyzed for eleven elements via inductively coupled plasma-mass spectrometry (ICP-MS). Selenium was significantly greater (p < 0.05) in the blood of captive turtles compared to wild turtles, while V, Ni, and Pb were significantly greater in the blood of wild turtles. In scute, V, Cu, Se, and Cr were significantly greater in captive turtles, while As was significantly greater in wild turtles. Pelleted food fed to the captive turtles and representative samples of the wild turtle diet were analyzed via ICP-MS to calculate trophic transfer factors and daily intake values. Wild turtles had greater estimated daily intake than captive turtles for all elements except Cu and Se. Because captive turtles are fed a diet very different from their wild counterparts, captive turtles do not represent control or reference samples for chemical exposure studies in wild turtles. No toxic thresholds are known for sea turtles, but rehabilitation and managed care facilities should monitor sea turtle elemental concentrations to ensure the animals’ health.

Faculty, Staff and Students Publications

BACKGROUND AND AIMS: South Asians (SA) experience disproportionately higher rates of atherosclerotic cardiovascular disease (ASCVD) events than non-Hispanic whites (NHW) and several other Asian groups. The coronary artery calcium (CAC) Agatston score may not capture the unique characteristics of coronary plaque in SA. We therefore evaluated the prevalence and patterns of advanced CAC measures (specific coronary vessel involvement, CAC volume and density) in SA versus other race/ethnicities.

METHODS: We combined data from the Mediators of Atherosclerosis in South Asians Living in America (MASALA) and Multi-Ethnic Study of Atherosclerosis (MESA) cohorts. We used multivariable-adjusted linear regression models to compare advanced CAC …

Hyperferritinemia is associated with poor outcomes in critically ill patients with sepsis, hemophagocytic lymphohistiocytosis (HLH), macrophage activation syndromes (MAS) and coronavirus disease 19 (COVID-19). Autopsies of hyperferritinemic patients that succumbed to either sepsis, HLH, MAS or COVID-19 have revealed disseminated microvascular thromboses with von Willebrand factor (VWF)-, platelets-, and/or fibrin-rich microthrombi. It is unknown whether high plasma ferritin concentration actively promotes microvascular thrombosis, or merely serves as a prognostic biomarker in these patients. Here, we show that secretion of VWF from human umbilical vein endothelial cells (HUVEC) is significantly enhanced by 100,000 ng/ml of recombinant ferritin heavy chain protein (FHC). …

Artificial Intelligence (AI), in general, refers to the machines (or computers) that mimic "cognitive" functions that we associate with our mind, such as "learning" and "solving problem". New biomarkers derived from medical imaging are being discovered and are then fused with non-imaging biomarkers (such as office, laboratory, physiological, genetic, epidemiological, and clinical-based biomarkers) in a big data framework, to develop AI systems. These systems can support risk prediction and monitoring. This perspective narrative shows the powerful methods of AI for tracking cardiovascular risks. We conclude that AI could potentially become an integral part of the COVID-19 disease management system. Countries, …


Entrapment Of A Partially Degloved Stent In The Radial Artery: Is There Any Way Out?, Nooraldaem Yousif, Husam A. Noor Dec 2020

Entrapment Of A Partially Degloved Stent In The Radial Artery: Is There Any Way Out?, Nooraldaem Yousif, Husam A. Noor

Journal of the Saudi Heart Association

Stent loss during percutaneous coronary intervention (PCI) is uncommon but may lead to serious adverse events. Here we describe a challenging case of stent loss in the radial artery during primary PCI. There, a long stent failed to cross the culprit lesion, and an attempt to pull back the undeployed stent into the guiding catheter resulted in eversion of the stent, partially stripping it off the stent balloon and rendering the stent irretrievable. Retrieval of the stent at all costs might have led to major complications; hence stent deployment in the radial artery bailed us out of this precarious situation.

Pharmaceutical drugs targeting dyslipidemia and cardiovascular disease (CVD) may increase the risk of fatty liver disease and other metabolic disorders. To identify potential novel CVD drug targets without these adverse effects, we perform genome-wide analyses of participants in the HUNT Study in Norway (n = 69,479) to search for protein-altering variants with beneficial impact on quantitative blood traits related to cardiovascular disease, but without detrimental impact on liver function. We identify 76 (11 previously unreported) presumed causal protein-altering variants associated with one or more CVD- or liver-related blood traits. Nine of the variants are predicted to result in loss-of-function of …

Progressive remodeling of the heart, resulting in cardiomyocyte (CM) loss and increased inflammation, fibrosis, and a progressive decrease in cardiac function, are hallmarks of myocardial infarction (MI)-induced heart failure. We show that MCB-613, a potent small molecule stimulator of steroid receptor coactivators (SRCs) attenuates pathological remodeling post-MI. MCB-613 decreases infarct size, apoptosis, hypertrophy, and fibrosis while maintaining significant cardiac function. MCB-613, when given within hours post MI, induces lasting protection from adverse remodeling concomitant with: 1) inhibition of macrophage inflammatory signaling and interleukin 1 (IL-1) signaling, which attenuates the acute inflammatory response, 2) attenuation of fibroblast differentiation, and 3) promotion …


A Review Of Bleeding Risk With Impella-Supported High-Risk Percutaneous Coronary Intervention, George W. Vetrovec, Amir Kaki, Thom G. Dahle Dec 2020

A Review Of Bleeding Risk With Impella-Supported High-Risk Percutaneous Coronary Intervention, George W. Vetrovec, Amir Kaki, Thom G. Dahle

Articles

Complex, high-risk percutaneous coronary intervention (HR-PCI) is increasingly being performed, often with mechanical circulatory support (MCS), though to date, there are limited randomised data on the efficacy of MCS for HR-PCI. The majority of MCS is provided by intra-aortic balloon pumps, but increasingly Impella® (Abiomed, Danvers, MA, USA) heart pumps are being used. While the Impella pumps provide greater increases in cardiac output, these devices require large bore access, which has been associated with an increased risk of bleeding and vascular complications. Decisions regarding the use of Impella are often based on risk–benefit considerations, with Impella-related bleeding risk being a …

A number of risk factors such as hypertension, obesity, smoking, and physical inactivity contribute to the significant rise of cardiovascular disease. Research data suggests that there is correlation between cardiovascular disease, low socioeconomic status, and diet. According to the American Phycological Association socioeconomic status is measured by income, educational status, and occupation, and has been shown to be closely …


An Exploratory On Partial Anomalous Pulmonary Venous Return (Papvr), Gabriella Pitingaro Dec 2020

An Exploratory On Partial Anomalous Pulmonary Venous Return (Papvr), Gabriella Pitingaro

Honors Projects

This exploratory gives insight into Partial Anomalous Pulmonary Venous Return (PAPVR). The paper goes into depth explaining more detail about the congenital heart defect, the embryology surrounding it, and how much is still left to be discovered. With PAPVR's rarity (0.4-0.7% of the population), not much is known. Hypocritically, since PAPVR often goes undetected, our numbers for cases are estimated to be an underestimated value. The paper also goes into a specific case study regarding the celebrity Amy Grant and her experience with PAPVR and how it has affected her life and career.

A Standardized Unit Based Process For Obtaining Heart Failure Patient Weights, Lesli E. Teed Dec 2020

A Standardized Unit Based Process For Obtaining Heart Failure Patient Weights, Lesli E. Teed

Master's Projects

Introduction: A CNL student-led process improvement process improvement project was proposed to help improve the accuracy of Heart Failure patient weights on a geriatric specialty unit. Cardiology voiced a preference for patients to be weighed using electronic standing scales rather than in-bed scales to improve accuracy. A literature review revealed that in-bed scale weights were less accurate due to inconsistencies in zeroing the bed prior to obtaining the weight, not removing excess patient care equipment and bed linens, and not ensuring that the patient was wearing a minimal amount of clothing.

Methods: Electronic standing scales were purchased, current practice state …

Treatment of giant cell myocarditis (GCM) can require bridging to orthotopic heart transplantation (OHT) or recovery with mechanical circulatory support (MCS). Since the roles of MCS and immunotherapy are not well-defined in GCM, we sought to analyze outcomes of patients with GCM who required MCS. A systematic search was performed in June 2019 to identify all studies of biopsy-proven GCM requiring MCS after 2009. We identified 27 studies with 43 patients. Patient-level data were extracted for analysis. Median patient age was 45 (interquartile range (IQR): 32–57) years. 42.1% (16/38) were female. 34.9% (15/43) presented in acute heart failure. 20.9% (9/43) …

Cardiovascular disease, which involves a wide range of conditions, including narrowed or blocked coronary arteries, has remained the leading cause of death in the United States for over 50 years. The majority of cardiovascular conditions are preventable, which can be identified through risk factors. However, maintaining healthy life choices can be difficult for most Americans, as the vast majority live in populated urban cities. Urban life can pose hazardous conditions to individuals, especially air pollution. Air pollution includes gaseous pollutants, such as carbon monoxide, nitrogen oxides, ozone and sulfur dioxide, and particulate matter. Of these pollutants, particulate matter has become …

The Cardiovascular Outcomes, Heart Failure And Kidney Disease Trials Tell That The Time To Use Sodium Glucose Cotransporter 2 Inhibitors Is Now., Michael E Johansen, Christos Argyropoulos

Heart and Vascular Articles

Sodium glucose contrasporter 2 inhibitors (SGLT2i) were initially introduced as a novel class of modestly effective antiglycemics. Over the last 5 years, multiple members of this class have been examined for their cardiovascular safety, effects on heart failure with reduced ejection fraction (HFrEF) and chronic kidney disease (CKD) in diverse populations with or without diabetes type 2. The plethora of studies and outcomes examined make it difficult for the practitioner to track the entirety of the evidence. SGLT2i improve cardiorenal outcomes and have a beneficial risk benefit ratio across populations with cardiovascular disease, HFrEF and kidney disease. In this quantitative …
