Introduction Spontaneous coronary artery dissection (SCAD) is a rare but important cause of acute coronary syndrome. SCAD involves the spontaneous formation of an intramural hematoma in coronary arteries, frequently presenting as severe acute-onset chest pain. Although extremely rare, cases of acute ischemic stroke (AIS) secondary to SCAD have been reported in the literature,,none of which were secondary to intracoronary thrombus displacement. In this report, we present the case of a 39-year-old man with no atherosclerotic risk factors who presented with […]

Abstract Cardiac amyloidosis (CA) is a progressive condition marked by the accumulation of amyloid fibrils in cardiac tissue, resulting in cardiac dysfunction and, ultimately, heart failure. Pyrophosphate scintigraphy has emerged as a promising tool for the early detection and monitoring of CA, providing valuable insights into the disease’s extent and severity. This review examines the current use of pyrophosphate scintigraphy in distinguishing between different types of amyloidosis, assessing risk levels, and monitoring patients with CA. It underscores the clinical significance […]

Abstract Background Femoral access remains a common choice in coronary angiography due to its easy accessibility and high success rate. Various techniques exist for achieving hemostasis following femoral artery catheterization. Objectives The aim of our study is to compare the methods of chitosan-containing hemostatic pad (HP) and manual compression (MC) in terms of efficacy and safety in patients undergoing percutaneous coronary intervention (PCI) with coronary angiography via femoral access. Method A total of 204 patients from 3 centers were included […]

Abstract Chagas disease (CD) is a neglected tropical disease (NTD) caused by Trypanosoma cruzi, a hemoflagellate protozoa. CD is diagnosed by epidemiologic history and two positive serological tests. The infection has two main clinical phases: acute, early after acquiring the infection, and chronic. The electrocardiogram (ECG) is the first tool to diagnose chronic Chagas heart disease after CD serological diagnosis. In addition, the different cardiac imaging modalities, including chest X-ray, echocardiography, single photon emission computed tomography (SPECT), computed tomography (CT), […]

Abstract Background Time in therapeutic range (TTR) plays an important role in the effectiveness of anticoagulant therapy with vitamin K antagonists. Objective To identify factors associated with variation in TTR. Methods The study sites were anticoagulation clinics at two university hospitals in Minas Gerais, with a total of 1357 patients studied. TTR was calculated using the Rosendaal method. Binary logistic regressions were carried out with the study variables, followed by multiple regression with those that were significant for the model, […]

Abstract Transthyretin amyloidosis (TTRA) is a systemic infiltrative disease where cardiac involvement is paramount for prognosis. The strain technique plays a crucial role in non-invasive cardiac screening for this condition. Research on the prognostic utility of cardiac deformation in TTRA indicates the significance of right ventricular (RV) free wall strain, global longitudinal strain (GLS), left and right atrium reservoir strain, in descending order of publication, respectively. The GLS has emerged as a promising tool for therapeutic monitoring. Analyzing myocardial deformation […]

Abstract Background Presystolic waves are often found during Doppler evaluation of the left ventricular outflow tract (LVOT) in hypertensive individuals. LV stiffness and altered LV compliance are potential mechanisms for presystolic waves. Objectives This study’s objective was to examine the relationship between presystolic wave and subclinical left ventricular (LV) impairment in asymptomatic individuals with essential hypertension. Methods This observational research comprised 87 individuals with essential hypertension. All patients had two-dimensional and Doppler echocardiography performed. Based on the existence or absence […]

Introduction Cardiac amyloidosis (CA) manifests as a gradually progressive infiltrative condition characterized by the accumulation of insoluble protein aggregates within the myocardium and cardiac conduction system. The majority of CA cases are associated with precursor proteins, particularly immunoglobulin light chains (AL-CA) and transthyretin (ATTR-CA), which represent over 95% of cases. ATTR precursor substances may originate from a broad spectrum, encompassing both wild-type (ATTRwt) and variant (ATTRv) genes. Arrhythmias in CA result from a combination of factors. The deposition of amyloid […]

Abstract In some transcatheter aortic valve implantation (TAVI) procedures, difficulty in crossing the valve delivery system occurs. There are some described anatomical risk factors as extreme angulation, heavy calcification, and bicuspid morphology. A possible reason may be an unfavorable angle of approach because of the outward push by the incoming crimped bioprosthesis and insufficient support/trackability of the extra stiff wire. Several techniques, tips, and tricks have been developed to overcome this problem and avoid procedure failures, such as the “pull-and-push” […]
