Alruthia, Waleed Alharbi, Owayed Alshammeri, Adel Tash, Shadi Almoziny, Naji Kholaif, Hussain Halawani, Fadia Almahdi, Wael Yar, Khalid F Alhabib

Journal of the Saudi Heart Association

Background: Despite robust evidence for low-density lipoprotein cholesterol (LDL-C) reduction in atherosclerotic cardiovascular disease (ASCVD) prevention, attainment of guideline-recommended targets remains suboptimal in Saudi Arabia, especially among high- and very high-risk patients. Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9)-targeted therapies, which include monoclonal antibodies (evolocumab, alirocumab) and small interfering RNA (inclisiran), offer potent LDL-C lowering that can help address this gap.

Methods: The Saudi Heart Association (SHA) convened a multidisciplinary panel to review evidence from randomized controlled trials, real-world studies, and economic analyses on PCSK9-targeted therapies. Recommendations were developed through expert consensus, contextualized to the Saudi healthcare environment.

Endo-Epicardial Ventricular Tachycardia Ablation In Arrhythmogenic Right Ventricular Cardiomyopathy- A Case Report, Selva Maheswari M Dr, Sharon Jabamalar Dr, Usnish Adhikari Dr, Deep Chandh Raja S Dr

Journal Of Indian Physician Associates

ABSTRACT:

Background

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare genetic disorder marked by progressive fibrofatty replacement of the right ventricle, causing life-threatening ventricular arrhythmias and sudden cardiac death (SCD). It is predominantly seen in young adults. As the substrate often involves both RV endocardium & epicardium, conventional ablation is often not successful. One of the effective therapies is combined endo- epicardial ablation, which gives good arrhythmia control and reduction of AICD (Automated Implantable Cardioverter Defibrillator) shock. Here we present two such cases.

Methods

Two patients presented with history of recurrent ventricular tachycardia (VT) which were reverted with DC (Direct …

Manuscripts, Articles, Book Chapters and Other Papers

A challenge of studying mammalian cardiac embryogenesis is the limited ability to perform experimental manipulations in animal models. The avian embryo is widely accepted as a model for mammalian heart developmental studies. In this study, we establish the methodology and protocols for studying the Japanese quail (Coturnix japonica) heart at embryonic day 10 (HH38) using the FUJIFILM VisualSonics Vevo 3100 ultrasound system equipped with a MX550D small animal cardiology transducer. These protocols were designed to measure right ventricular wall thickness, pulmonary artery diameter, and the outflow velocities of the right ventricular outflow tract (RVOT) and the pulmonary artery …

Interventional Approach To Intermediate-High-Risk Pe: Catheter-Directed Mechanical Thrombectomy, Shreya Agarwal, Kirill Ruban, Ishan Kirti, Karina Ruban, Fadi Saab, Sujata Kambhatla, Pranay Gupta

Conference Presentation Abstracts

Acute pulmonary embolism (PE) is a major cause of cardiovascular morbidity and mortality. The clinical outcomes are largely determined by thrombus burden and its hemodynamic impact on the right ventricle (RV). Over the past decade, catheter-directed mechanical thrombectomy has emerged as a promising alternative for systemic thrombolysis for PE management, particularly in patients at high risk for major bleeding. This approach provides rapid mechanical debulking of thrombus without exposure to thrombolytics and has been associated with significant improvements in RV function and pulmonary artery pressures. We present a case of extensive bilateral PE successfully treated with mechanical thrombectomy, highlighting the …

Heart and Vascular Articles

IMPORTANCE: Female patients with heart failure (HF) are older and more often present with preserved left ventricular ejection fraction (LVEF), whereas male patients present with more ischemic disease. Despite these differences, an emergency department-based acute HF strategy may be equally applicable to both sexes.

OBJECTIVE: To determine whether the strategy for acute HF management in the Comparison of Outcomes and Access to Care for Heart Failure (COACH) trial differed by sex.

DESIGN, SETTING, AND PARTICIPANTS: This prespecified secondary analysis of the multicenter COACH stepped-wedge, cluster-randomized clinical trial included 10 acute care hospitals in Ontario, Canada. Data were collected from January …

Evaluation Of The Effectiveness Of Antihypertensive Therapy Chosen Through Maternal Hemodynamic Profile Analysis, Margaret Weimer

Poster Presentations

In treatment of emergent hypertension, the American College of Obstetricians and Gynecologists (ACOG) recommends both oral labetalol and nifedipine, with no preference shown between the two. These medications have different mechanisms of action. Studies have suggested that consideration of hemodynamic profile may be an effective way to determine medication, but have not considered the Rule of 55, a simple calculation to predict hemodynamic profile.

Goals: 1. Determine if tailoring the antihypertensive to patient’s hemodynamic profile is associated with better control of blood pressure. 2. Determine if the Rule of 55 is an accurate method to determine hemodynamic profile.

Spontaneous Coronary Artery Dissection In Postpartum: A Hidden Cause Of Maternal Myocardial Infarction, Riya Chhabra, Brian Renard

Conference Presentation Abstracts

Spontaneous coronary artery dissection (SCAD) is a tear in the coronary artery lining which decreases blood flow to the heart. SCAD is the leading cause of myocardial infarction in young to middle aged women, especially during and after pregnancy. While SCAD is often managed conservatively, patients are prone to complications like cardiomyopathy. This case underscores the importance of considering SCAD as a differential for postpartum women with chest pain. Furthermore, this case highlights the diagnosis and management of an atypical stress-induced cardiomyopathy with global hypokinesis following postpartum SCAD. A 37-year-old female postpartum for five weeks presented to our hospital with …
