Diagnostic Accuracy of Cardiac Magnetic Resonance Versus Fractional Flow Reserve: A Systematic Review and Meta-Analysis

Abstract Background Fractional flow reserve (FFR) is considered the gold standard for diagnosis of coronary artery disease (CAD). Stress Cardiac magnetic resonance (SCMR) has been recently gaining traction as a non-invasive alternative to FFR. Methods Studies comparing the diagnostic accuracy of SCMR versus FFR were identified and analyzed using Review Manager (RevMan) 5.3 and Stata […]

Primary Cardiac Undifferentiated High-Grade Intimal Pleomorphic Sarcoma

Introduction Primary cardiac sarcomas (PCSs) are extremely rare with only a few cases reported in the literature. About 25% of primary cardiac tumors are malignant, and of those 75% are sarcomas [1]. Radiologic similarities to benign myxomas/thrombus make PCSs a diagnostic challenge. Clinical presentations of PCSs include cerebrovascular accident, pulmonary embolism (PE), valvular dysfunctions, arrhythmias, […]

Erdheim-Chester Disease With Extensive Pericardial Involvement: A Case Report and Systematic Review

Abstract Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis characterized by systemic xanthogranulomatous infiltration. We described the case of a female adult presenting with pericardial effusion. Pericardial infiltration is the most frequent cardiac manifestation of ECD and is the one discussed in this article. We found that the majority of patients with pericardial infiltration […]

Early Structural Deterioration of a Sutureless Bioprosthetic Aortic Valve

Abstract Sutureless bioprosthetic valves such as the Sorin Perceval S valve (SPV) have been used in patients with aortic stenosis that require surgical aortic valve replacement (SAVR). These prostheses have been marketed on the basis of their rapid implantation techniques with avoidance of sutures and reduced aortic cross-clamp times. We report a case of an […]

Correlation Between the Cardio-Ankle Vascular Index and Renal Resistive Index in Patients With Essential Hypertension

Abstract Background Renal resistive index (RRI) is a parameter determined by Doppler sonography that reflects renal hemodynamics. Significant relationships connecting increases in the RRI with cardiovascular risk factors and the incidence of cardiovascular disease in hypertensive patients have been reported. This cross-sectional study aimed to clarify the relationship between cardio-ankle vascular index (CAVI), a novel […]

Incidence of Atrioventricular Block After Valve Replacement in Carcinoid Heart Disease

Incidence of Atrioventricular Block After Valve Replacement in Carcinoid Heart Disease Abstract Background Carcinoid heart disease (CaHD) is a rare condition that has a high impact on the morbidity and mortality of its patients. Once heart failure symptoms develop in the patient with CaHD, cardiac valve surgery is often the only effective treatment. Although atrioventricular […]

Ventricular Tachycardia in an Infant Without Congenital Anomaly: A Case Report

Abstract Ventricular tachycardia (VT) is a serious form of arrhythmia that can be life-threatening; that’s why diagnosis and treatment are very important in order to avoid serious complications. We are reporting this case of VT which is a rare entity, especially, in healthy infants. This infant, without cardiac pathology known from birth, presented with poor […]

Peripheral Embolization of Left Ventricular Thrombus Leading to Acute Bilateral Critical Limb Ischemia: A Rare Phenomenon

Abstract Left ventricular thrombus (LVT) is a well-known complication of myocardial infarction (MI) leading to significant morbidity and mortality. LVT can also lead to systemic thromboembolic events causing threatening limb ischemia. We report a rare case of critical bilateral limb ischemia that resulted from peripheral embolization of LVT post MI, which was managed successfully by […]

Paroxysmal Atrial Fibrillation: Insight Into the Intimate Mechanisms of Coagulation

Paroxysmal Atrial Fibrillation: Insight Into the Intimate Mechanisms of Coagulation Abstract Background Atrial fibrillation (AF) is a hypercoagulable state. However, the intimate mechanisms leading to impaired coagulation and the timing of their activation are unclear. The aim of the study was to investigate the factors that initiate the coagulation cascade in the early hours (up […]

Trajectory of Cardiac Catheterization for Acute Coronary Syndrome and Out-of-Hospital Cardiac Arrest During the COVID-19 Pandemic

Background We sought to investigate the trajectory of cardiac catheterizations for acute coronary syndrome (ACS) and out-of-hospital cardiac arrest (OHCA) during the pre-isolation (PI), strict-isolation (SI), and relaxed-isolation (RI) periods of the coronavirus disease 2019 (COVID-19) pandemic at three hospitals in Los Angeles, CA, USA. Methods A retrospective analysis was conducted on adult patients undergoing […]

Evaluation of Index of Cardio-Electrophysiological Balance in Patients With Atrial Fibrillation on Antiarrhythmic-Drug Therapy

Background Index of cardio-electrophysiological balance (iCEB) has been described as a novel risk marker for predicting malignant ventricular arrhythmia. There remains limited evidence on the effects of amiodarone and propafenone used for sinus rhythm maintenance on iCEB in patients with atrial fibrillation (AF). The aim of this study was to evaluate iCEB in patients with […]

Virtual Versus In-Person Learning as a Cardiologist During COVID-19 Pandemic

One of the high points of my academic year has been the annual American Heart Association (AHA) meeting. It has been a time to meet colleagues from around the world, as well as to update my knowledge in cardiovascular diseases; both basic and clinical research. More and more the “late breaking clinical trials” has been […]

Predictability of Inpatient Mortality of Different Comorbidities in Both Types of Acute Decompensated Heart Failure

Methods We conducted a retrospective cohort study utilizing the Healthcare Cost and Utilization Project National Inpatient Sample (HCUP-NIS) 2016 database. Results There were totally 116,189 admissions for acute decompensated heart failure (ADHF). Of these, 50.9% were for heart failure with reduced ejection fraction (HFrEF) group (n = 59,195), and 49.1% were for heart failure with […]

Predictors of Mitral Regurgitation Severity Improvement in Patients With Severe Aortic Stenosis Undergoing Transcatheter Aortic Valve Implantation

Abstract Background Mitral regurgitation (MR) is frequently associated with severe aortic stenosis (AS). Significant MR is associated with less favorable prognosis after transcatheter aortic valve implantation (TAVI), including higher early and late mortality rate. The severity of MR is improved in about half of patients undergoing TAVI. However, the predictors of MR improvement after TAVI […]

Some Aspects of Role of Nitric Oxide in the Mechanisms of Hypertension (Experimental Study)

Abstract Background Modulation of endothelial function is a therapeutic option to reduce some of the significant complications of hypertension. However, the relationship between endothelial dysfunction reduced nitric oxide (NO) production, and the development of hypertension is not fully understood. To establish a potential pathogenetic link between impaired NO synthesis and hypertension, we investigated the results […]
