INTRODUCTION: Heterozygous autosomal-dominant single nucleotide variants in RYR2 account for 60% of cases of catecholaminergic polymorphic ventricular tachycardia (CPVT), an inherited arrhythmia disorder associated with high mortality rates. CRISPR/Cas9-mediated genome editing is a promising therapeutic approach that can permanently cure the disease by removing the mutant RYR2 allele. However, the safety and long-term efficacy of this strategy have not been established in a relevant disease model.

AIM: The purpose of this study was to assess whether adeno-associated virus type-9 (AAV9)-mediated somatic genome editing could prevent ventricular arrhythmias by removal of the mutant allele in mice that are heterozygous for

Effects Of Bioprosthetic Valve Fracturing On Valve-In-Valve Transcatheter Aortic Valve Implantation Transvalvular Gradients, Osama Hallak, Karley Fischer, Shaina Ailawadi, Damian Valencia, Yan Yatsynovich, Raja Nazir, Brian Schwartz

The Texas Heart Institute Journal

BACKGROUND: Valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) is quickly becoming a routine and effective means by which to treat degenerated bioprosthetic valves. A known complication of ViV-TAVI is patient-prosthesis mismatch, which substantially affects survival. Bioprosthetic valve fracture is a method by which to reduce the risk of patient-prosthesis mismatch and post-ViV-TAVI transvalvular gradients. This study sought to determine the safety and efficacy of post-ViV-TAVI bioprosthetic valve fracture.

METHODS: Patients with a history of surgical aortic valve replacement undergoing ViV-TAVI bioprosthetic valve fracture (N = 25) at the corresponding institution from 2015 to 2022 were cataloged for a retrospective analysis. …

METHODS: Trends in CVD-related mortality were evaluated through analysis of the Multiple Causes of Death Files from the National Center for Health Statistics. Crude and age-adjusted mortality rates (AAMRs) per 100,000 population with associated annual percentage changes were determined. Joinpoint regression was used to assess trends …

The Great Masquerade: Not All Coronary Artery Stenosis Are Created Equal, Prasanti A Kotta, Ajit K Koduri, Jeffrey Berman, Veronica V Rosen, Waleed T Kayani

Faculty, Staff and Students Publications

We present the case of a 60-year-old male, with active smoking and cocaine use disorder, who reported progressive chest pain. Various anatomical and functional cardiac imaging, performed to further evaluate chest pain etiology, revealed changing severity and distribution of left main artery (LMA) stenosis, raising suspicion for vasospasm. Intracoronary nitroglycerin relieved the vasospasm, with resolution of the LMA pseudostenosis. A diagnosis of vasospastic angina (VA) led to starting appropriate medical therapy with lifestyle modification counselling. This case highlights VA, a frequently underdiagnosed etiology of angina pectoris. We discuss when to suspect VA, its appropriate work-up, and management.

Mitral Valve Regurgitation In Klippel-Feil Syndrome With Related Thoracic Deformity, Yuki Endo, Yoshiei Shimamura, Hiroshi Niinami

The Texas Heart Institute Journal

Klippel-Feil syndrome, characterized by congenital fusion of any 2 or more cervical vertebrae, is a rare disorder in which skeletal and other organ system-related abnormalities have been reported. This article reports a case of mitral valve regurgitation in a patient with Klippel-Feil syndrome and related thoracic deformity who underwent mitral valvuloplasty. Postoperatively, the mitral valve regurgitation disappeared, and there has been no recurrence for 3 years. This case highlights mitral valvuloplasty via median sternotomy as an excellent treatment for mitral valve regurgitation in a patient with thoracic deformity related to Klippel-Feil syndrome.

Autonomic Modulation Of Cardiac Function In Hypertrophic Cardiomyopathy, Jenna Rose Disser

Dissertations, Master's Theses and Master's Reports

Hypertrophic cardiomyopathy (HCM) is the most common genetic heart disorder. HCM is characterized by cardiac hypertrophy, fibrosis, and an increased risk of fatal arrhythmias and sudden cardiac death. Previous studies in humans with HCM have demonstrated increased cardiac norepinephrine spillover and reduced beta-1 receptor (β1R) expression in the left ventricle (LV). We have previously demonstrated that cardiac sympathetic tone is elevated in an alpha-tropomyosin mutant mouse model of HCM. We hypothesized that HCM mice would demonstrate reduced β1R expression in the LV and attenuated heart rate (HR) and dP/dt max responses to ramped infusion of the β1R agonist, dobutamine. …

Use Of Extracorporeal Membrane Oxygenation-Facilitated Large-Bore Catheter Embolectomy In The Treatment Of Acute Pulmonary Embolism Complicated By Shock, Hugh A Glazier, Amir Kaki

The Texas Heart Institute Journal

This article reports the case of a 42-year-old man who presented with a saddle pulmonary embolus complicated by normotensive cardiogenic shock. The patient was first stabilized with venoarterial extracorporeal membrane oxygenation. Then, while the patient was still on extracorporeal membrane oxygenation, thrombectomy with a large-bore catheter device was performed that resulted in a large decrease in pulmonary artery pressures and a clinically significant increase in cardiac index, with rapid clinical improvement. Complete recovery of the patient's cardiopulmonary status has been maintained at intermediate-term follow-up. This treatment strategy should be considered favorably in the treatment of patients presenting with pulmonary embolism …

Sex Differences In The Association Between Cardiac Vagal Control And The Effects Of Baroreflex Afferents On Behavior, Xiao Yang, Jacob Chaney, Aaron S. David, Fang Fang

Psychology Faculty Publications

Background: Cardiovascular disease (CVD) is the leading cause of mortality and disability worldwide. While sex differences in CVD have been well documented, the physiological mechanisms of those sex differences remain unclear. As important components of the cardiovascular system, cardiac vagal control and baroreflex serve as mechanisms of sex differences in CVD and are modifiable factors for gender-specific CVD preventions. Methods: Ninety-four healthy adults (18–44 years of age; M_age = 21.09 years; 46 female) were recruited to complete the assessments of heart rate variability (HRV) at a resting baseline and the cardiac timing effect on an R-wave-locked reaction time (RT) …

Faculty, Staff and Student Publications

Clonal hematopoiesis (CH) is an independent risk factor for atherosclerotic cardiovascular disease. Murine models of CH suggest a central role of inflammasomes and IL-1β in accelerated atherosclerosis and plaque destabilization. Here we show using single-cell RNA sequencing in human carotid plaques that inflammasome components are enriched in macrophages, while the receptor for IL-1β is enriched in fibroblasts and smooth muscle cells (SMCs). To address the role of inflammatory crosstalk in features of plaque destabilization, we conducted SMC fate mapping in Ldlr-/- mice modeling Jak2VF or Tet2 CH treated with IL-1β antibodies. Unexpectedly, this treatment minimally affected SMC differentiation, …

Adipose Tissue Lymphocytes And Obesity, Feng Gao, Benjamin Litchfield, Huaizhu Wu

Faculty, Staff and Students Publications

Obesity is associated with chronic inflammation in adipose tissue (AT), mainly evidenced by infiltration and phenotypic changes of various types of immune cells. Macrophages are the major innate immune cells and represent the predominant immune cell population within AT. Lymphocytes, including T cells and B cells, are adaptive immune cells and constitute another important immune cell population in AT. In obesity, CD8+ effector memory T cells, CD4+ Th1 cells, and B2 cells are increased in AT and promote AT inflammation, while regulatory T cells and Th2 cells, which usually function as immune regulatory or type 2 inflammatory cells, are reduced …

Anomalous Aortic Origin Of A Coronary Artery In Pediatric Patients, Tam T Doan, Charles Puelz, Craig Rusin, Silvana Molossi

Faculty, Staff and Students Publications

PURPOSE OF REVIEW: We present a contemporary approach to risk assessment and management of patients with anomalous aortic origin of a coronary artery (AAOCA).

RECENT FINDINGS: Anomalous left coronary artery from the right aortic sinus (L-AAOCA) with interarterial course carries a high risk of sudden cardiac death (SCD); therefore, current guidelines recommend exercise restriction and surgical intervention. Recent data in intraseptal and juxtacommissural L-AAOCA showed inducible perfusion abnormalities, leading to consideration of surgical intervention. Anomalous right coronary artery from the left aortic sinus (R-AAOCA) carries a much lower risk and stress perfusion imaging is helpful in identifying patients with inducible …

Efektivitas Sacubitril/Valsartan Dalam Mencegah Gagal Jantung Pada Stemi Pasca Percutaneous Coronary Intervention, Nobian Andre, Lana Adila, Aulia Rizka, Lusiani Rusdi

Jurnal Penyakit Dalam Indonesia

Heart failure is a possible complication following ST-elevation myocardial infarction (STEMI) even after revascularization. Neuroendocrine activation in the process of ventricular remodeling can be regulated by angiotensin receptor-neprilysin inhibitor (ARNI) as well as angiotensin-converting enzyme (ACE) inhibitor. The use of ARNI in heart failure with reduced ejection fraction has been found to be superior to ACE inhibitor. The role of ARNI on cardiac function in STEMI has not been established. A clinician treating a patient with STEMI considered giving sacubitril/valsartan to reduce the risk of developing heart failure. Literature search was performed in three electronic databases: PubMed, Embase, and Cochrane. …

Faculty, Staff and Student Publications

AIMS: Mutations in the DSP gene encoding desmoplakin, a constituent of the desmosomes at the intercalated discs (IDs), cause a phenotype that spans arrhythmogenic cardiomyopathy (ACM) and dilated cardiomyopathy. It is typically characterized by biventricular enlargement and dysfunction, myocardial fibrosis, cell death, and arrhythmias. The canonical wingless-related integration (cWNT)/β-catenin pathway is implicated in the pathogenesis of ACM. The β-catenin is an indispensable co-transcriptional regulator of the cWNT pathway and a member of the IDs. We genetically inactivated or activated β-catenin to determine its role in the pathogenesis of desmoplakin cardiomyopathy.

METHODS AND RESULTS: The Dsp gene was conditionally deleted in …
