Spontaneous coronary artery dissection (SCAD) is a potential precipitant of myocardial infarction and sudden death for which the etiology is poorly understood. Mendelian vascular and connective tissue disorders underlying thoracic aortic disease (TAD), have been reported in ~5% of individuals with SCAD. We therefore hypothesized that patients with TAD are at elevated risk for SCAD. We queried registries enrolling patients with TAD to define the incidence of SCAD. Of 7568 individuals enrolled, 11 (0.15%) were found to have SCAD. Of the sequenced cases (9/11), pathogenic variants were identified (N = 9), including COL3A1 (N = 3), FBN1 (N = 2), …

Supracardiac Total Anomalous Pulmonary Venous Return Repair In A 7-Month-Old Infant, Mislav Planinc, Ivan Malcic, Darko Anic

The Texas Heart Institute Journal

Total anomalous pulmonary venous return is a congenital heart malformation characterized by anomalous pulmonary venous inflow to the right atrium. Surgical repair typically occurs during the first month of life, and survival beyond that age in untreated patients is unlikely. We report an extreme case of supracardiac total anomalous pulmonary venous return in an infant who survived 7 months despite atypical anomalous inflow without atrial-level communication and with right-to-left shunting only through a patent ductus arteriosus. We stabilized the patient's left-sided heart function before surgically repairing the anomalous venous return 2 months later. Three years postoperatively, the patient was well.

Repurposing Probenecid For The Treatment Of Heart Failure (Re-Prosper-Hf): A Study Protocol For A Randomized Placebo-Controlled Clinical Trial, Jack Rubinstein, Nathan Robbins, Karen Evans, Gabrielle Foster, Kevin Mcconeghy, Toluwalope Onadeko, Julie Bunke, Melanie Parent, Xi Luo, Jacob Joseph, Wen-Chih Wu

Faculty, Staff and Student Publications

BACKGROUND: Improving contractility in heart failure with reduced ejection fraction (HFrEF) has resurfaced as a potential treatment goal. Inotropic therapy is now better understood through its underlying mechanism as opposed to the observed effect of increasing contractility. Calcitropes are a subgroup of inotropes that largely depend on the stimulation of adenylyl cyclase to transform ATP into cyclic adenosine monophosphate (cAMP). At least two clinically relevant calcitropes-istaroxime and probenecid-improve contractility through an increase in systolic intracellular calcium without activating cAMP production. Probenecid, which has been safely used clinically for decades in non-cardiac conditions, has recently been identified as an agonist of …

Identification Of Genetic Loci Simultaneously Associated With Multiple Cardiometabolic Traits, Alexis C Wood, Amit Arora, Michelle Newell, Victoria L Bland, Jin Zhou, Nicola Pirastu, Jose M Ordovas, Yann C Klimentidis

Children’s Nutrition Research Center Staff Publications

Background and aims: Cardiometabolic disorders (CMD) arise from a constellation of features such as increased adiposity, hyperlipidemia, hypertension and compromised glucose control. Many genetic loci have shown associations with individual CMD-related traits, but no investigations have focused on simultaneously identifying loci showing associations across all domains. We therefore sought to identify loci associated with risk across seven continuous CMD-related traits.

Methods and results: We conducted separate genome-wide association studies (GWAS) for systolic and diastolic blood pressure (SBP/DBP), hemoglobin A1c (HbA1c), low- and high- density lipoprotein cholesterol (LDL-C/HDL-C), waist-to-hip-ratio (WHR), and triglycerides (TGs) in the UK Biobank (N = 356,574-456,823). Multiple …

Continuous Thoracic Paravertebral Block To Treat Electrical Storm, Daryl I Smith, Sarah A Kralovic, Rafeek A Hegazy, Hai Tran

The Texas Heart Institute Journal

Continuous ganglion block is increasingly being used to help manage ventricular tachyarrhythmias. We present the cases of 2 patients in whom we used continuous left thoracic paravertebral block to achieve sympathetic denervation and improvement in drug-refractory ventricular tachyarrhythmias. Whether as destination therapy or bridging therapy, we conclude that the block is safe, improves patients' comfort, and is superior in several ways to stellate ganglion block and other single-injection techniques.

Silent Kawasaki Disease Affecting Multiple Coronary Arteries In A 39-Year-Old Egyptian Woman, Hamdy Singab, Gamal Sami, Mahmoud Tag El Sabah

The Texas Heart Institute Journal

Kawasaki disease, an acute febrile illness, can cause vasculitis in the coronary arteries. It is the chief acquired cause of myocardial infarction and sudden cardiac death in infants, children, and young adults in developed countries. We report a case of chronic, silent Kawasaki disease complicated by multivessel thrombosis in a 39-year-old Egyptian woman. The patient presented with progressive, unstable angina but was otherwise asymptomatic and at negligible risk of ischemic heart disease. Coronary angiograms showed critical arterial stenosis with multiple aneurysms. During revascularization surgery, the patient's harvested left internal mammary artery was found to have occlusive lesions and aneurysmal areas …

Faculty, Staff and Student Publications

Background and purpose: Clonal hematopoiesis of indeterminate potential (CHIP) is a novel age-related risk factor for cardiovascular disease-related morbidity and mortality. The association of CHIP with risk of incident ischemic stroke was reported previously in an exploratory analysis including a small number of incident stroke cases without replication and lack of stroke subphenotyping. The purpose of this study was to discover whether CHIP is a risk factor for ischemic or hemorrhagic stroke.

Methods: We utilized plasma genome sequence data of blood DNA to identify CHIP in 78 752 individuals from 8 prospective cohorts and biobanks. We then assessed the association …

Stroke is the second leading cause of mortality globally with higher burden and younger age in low-middle income countries (LMICs) than high-income countries (HICs). However, it is unclear to what extent differences in healthcare access and quality (HAQ) and prevalence of risk factors between LMICs and HICs contribute to younger age of stroke in LMICs. In this systematic review, we conducted meta-analysis of 67 articles and compared the mean age of stroke between LMICs and HICs, before and after adjusting for HAQ index. We also compared the prevalence of main stroke risk factors between HICs and LMICs. The unadjusted mean …

RESULTS: Among 40 814 acute ischemic stroke cases in Texas in 2019, 54% were White, 17% Black, and 21% Hispanic. Black patients had similar admissions …

Radiation Doses In Patients Undergoing Computed Tomographic Coronary Artery Calcium Evaluation With A 64-Slice Scanner Versus A 256-Slice Scanner, Paul Madaj, Dong Li, Rine Nakanishi, Daniele Andreini, Gianluca Pontone, Edoardo Conte, Rachael O'Rourke, Christian Hamilton-Craig, Manojna Nimmagadda, Nicholas Kim, Badiha Fatima, Christopher Dailing, Kashif Shaikh, Chandana Shekar, Ju Hwan Lee, Matthew J Budoff

The Texas Heart Institute Journal

Computed tomographic coronary artery calcium scanning enables cardiovascular risk stratification; however, exposing patients to high radiation levels is an ongoing concern. New-generation computed tomographic systems use lower radiation doses than older systems do. To quantify comparative doses of radiation exposure, we prospectively acquired images from 220 patients with use of a 64-slice GE LightSpeed VCT scanner (control group, n=110) and a 256-slice GE Revolution scanner (study group, n=110). The groups were matched for age, sex, and body mass index; statistical analysis included t tests and linear regression.

The mean dose-length product was 21% lower in the study group than in …

RATIONALE: Dextro-transposition of the great arteries (D-TGA) is a severe congenital heart defect which affects approximately 1 in 4,000 live births. While there are several reports of D-TGA patients with rare variants in individual genes, the majority of D-TGA cases remain genetically elusive. Familial recurrence patterns and the observation that most cases with D-TGA are sporadic suggest a polygenic inheritance for the disorder, yet this remains unexplored.

OBJECTIVE: We sought to study the role of common single nucleotide polymorphisms (SNPs) in risk for D-TGA.

METHODS AND RESULTS: We conducted a genome-wide association study in an international set of 1,237 patients …

Faculty, Staff and Student Publications

The Cre-LoxP technology, including the tamoxifen (TAM) inducible MerCreMer (MCM), is increasingly used to delineate gene function, understand the disease mechanisms, and test therapeutic interventions. We set to determine the effects of TAM-MCM on cardiac myocyte transcriptome. Expression of the MCM was induced specifically in cardiac myocytes upon injection of TAM to myosin heavy chain 6-MCM (Myh6-Mcm) mice for 5 consecutive days. Cardiac function, myocardial histology, and gene expression (RNA-sequencing) were analyzed 2 weeks after TAM injection. A total of 346 protein coding genes (168 up- and 178 down-regulated) were differentially expressed. Transcript levels of 85 genes, analyzed …

Quantification Of Infarct Core Signal Using Ct Imaging In Acute Ischemic Stroke, Uma Maria Lal-Trehan Estrada, Grant Meeks, Sergio Salazar-Marioni, Fabien Scalzo, Mudassir Farooqui, Juan Vivanco-Suarez, Santiago Ortega Gutierrez, Sunil A Sheth, Luca Giancardo

Faculty, Staff and Student Publications

In stroke care, the extent of irreversible brain injury, termed infarct core, plays a key role in determining eligibility for acute treatments, such as intravenous thrombolysis and endovascular reperfusion therapies. Many of the pivotal randomized clinical trials testing those therapies used MRI Diffusion-Weighted Imaging (DWI) or CT Perfusion (CTP) to define infarct core. Unfortunately, these modalities are not available 24/7 outside of large stroke centers. As such, there is a need for accurate infarct core determination using faster and more widely available imaging modalities including Non-Contrast CT (NCCT) and CT Angiography (CTA). Prior studies have suggested that CTA provides improved …

A Right Atrial Mass With Fever And Cutaneous Nodules, Feng Gao, Stephanie Koh, Sara Taveras-Alam, Umair Khalid

Faculty, Staff and Student Publications

Primary cardiac tumors, although exceedingly rare, should be considered in the differential diagnosis during workup of any cardiac mass. Extranodal cardiac lymphomas have a natural aggressive course due to delayed diagnosis. We present a 71-year-old male with a dual-chamber pacemaker who presented with fevers and new cutaneous nodules. He was found to have a right atrial primary anaplastic large-cell lymphoma and had a complete metabolic response after chemotherapy. Our case highlights the importance of a multimodality approach in the diagnosis of cardiac tumors and during follow-up after treatment.

Very Late Aortic Endograft Infection With Listeria Monocytogenes In An Elderly Man, Jorge A Miranda, Ahmed Khouqeer, James J Livesay, Miguel Montero-Baker

The Texas Heart Institute Journal

Endograft infection with Listeria monocytogenes is a rare, potentially devastating complication of endovascular aortic aneurysm repair. To our knowledge, only 8 cases have been reported. We describe the case of a 72-year-old man who presented with L. monocytogenes endograft infection and a 19-cm degenerative aneurysm 9 years after having undergone endovascular repair of an abdominal aortic aneurysm. The infection was successfully treated with open surgical excision of the infected aortoiliac endograft and its replacement with a rifampin-soaked, bifurcated Dacron graft.

The Texas Heart Institute Journal

Phlegmasia cerulea dolens, a rare and potentially fatal complication of acute deep vein thrombosis, is characterized by substantial edema, intense pain, and cyanosis. Phlegmasia cerulea dolens may compromise limb perfusion and lead to acute ischemia, gangrene, amputation, and death. We present the case of a 61-year-old woman with a history of breast cancer who had signs and symptoms of phlegmasia cerulea dolens in her left leg. She was treated promptly with open surgical thrombectomy and sequential distal compression with use of an Esmarch bandage to ensure complete thrombus extraction. These techniques restored venous flow and saved her leg. Open surgical …

Kidney Disease After Heart And Lung Transplantation, Carlos M Zapata, Hassan N Ibrahim

Faculty, Staff and Student Publications

Chronic kidney disease (CKD) is not only common after lung and heart transplantation but also is associated with increased morbidity and mortality due to multiple pre-, peri- and post-transplant factors. While the exact incidence of CKD in this population is not well-defined, it seems to have gradually increased over the years as older recipients are more frequently considered. The increasing success of the procedure and expanding transplant candidate pool has allowed many with comorbid conditions to receive a transplant, which was considered prohibitive in the past. This review presents risk factors that have been linked to CKD as well as …

Numerous studies have revealed the critical role of premature senescence induced by various cancer treatment modalities in the pathogenesis of aging-related diseases. Senescence-associated secretory phenotype (SASP) can be induced by telomere dysfunction. Telomeric DNA damage response induced by some cancer treatments can persist for months, possibly accounting for long-term sequelae of cancer treatments. Telomeric DNA damage-induced mitochondrial dysfunction and increased reactive oxygen species production are hallmarks of premature senescence. Recently, we reported that the nucleus-mitochondria positive feedback loop formed by p90 ribosomal S6 kinase (p90RSK) and phosphorylation of S496 on ERK5 (a unique member of the mitogen-activated protein kinase family …
