Misinterpretation of indeterminate diastolic dysfunction: awareness and insights from a nationwide survey among Brazilian cardiologists

INTRODUCTION: Cardiac diastolic dysfunction is highly prevalent and is associated with significant morbidity and mortality. The latest American Society of Echocardiography and European Association of Cardiovascular Imaging (ASE/EACVI) guidelines have simplified the definition of diastolic dysfunction and...

The role of cardiac magnetic resonance imaging during pregnancy - a challenging early diagnosis of a congenital heart condition

DESCRIPTION OF CLINICAL PRESENTATION: Congenital heart defects affect, approximately, 1% of the population and standard echocardiography can have limited diagnostic accuracy in certain cases. Fetal cardiac magnetic resonance (fCMR) has potential to clarify anatomic information, improving prenatal diagnos...

Avanços na escolha do método de imagem cardiovascular na inflamação e aterosclerose
Advances in cardiovascular imaging of inflammationand atherosclerosis

As doenças cardiovasculares, especialmente a doença arterial coronariana crôni-ca (DAC), são a principal causa de mortalidade tanto globalmente quanto no Brasil.Os avanços na imagem cardíaca, envolvendo a ecocardiografia, a tomografia computa-dorizada (TC) e a ressonância magnética (RM), têm des...

Diagnostic accuracy of artificial intelligence-based electrocardiogram algorithm to predict heart failure with reduced ejection fraction: a systematic review and meta-analysis

Circulation; 150 (Suppl. 1), 2024
INTRODUCTION: AI-based EKG has shown good accuracy for diagnosing heart failure. However, due to the heterogeneity of studies regarding cutoff points, its precision for specifically detecting heart failure with reduced ejection fraction (LVEF <40%) is not yet well established. Research question: What it ...

Identifying the impact of systolic dysfunction on CKD risk in HFpEF patients

Circulation; 150 (Suppl. 1), 2024
INTRODUCTION: Chronic kidney disease (CKD) is a critical comorbidity in heart failure with preserved ejection fraction (HFpEF), often linked to congestion due to elevated filling pressures. However, the role of subtle systolic dysfunction in CKD remains to be elucidated. This study aimed to investigate t...

Clinical and genetic profiles of patients with hereditary and wild type transthyretin amyloidosis: the transthyretin cardiac amyloidosis registry in the state of Sao Paulo, Brazil REACT-SP

Eur. heart j; 45 (Suppl. 1), 2024
INTRODUCTION: Transthyretin amyloidosis (ATTR) is a multisystem disease caused by the deposition of fibrillar protein in organs and tissues. ATTR genotypes and phenotypes are highly heterogeneous. PURPOSE: We designed the Transthyretin Cardiac Amyloidosis Registry in the state of São Paulo (REACT-SP), a...

Restenosis, procedural success and long-term outcomes after percutaneous mitral balloon commissurotomy in rheumatic mitral disease: large single-center experience

J. Am. Coll. Cardiol; 84 (18 Suppl. B), 2024
BACKGROUND Percutaneous mitral balloon commissurotomy (PMBC) remains the fust choice of treatment in appropriate candidates with mitral valve (MV) stenosis (MS) and ideal anatomy. The objective of this study was to identify the risk factors of MV restenosis in a large cohort of patients submitted to PMBC...

Fechamento percutâneo do refluxo paraprotético: análise clínica e ecocardiográfica em pacientes de alto risco cirúrgico - resultados e desafios
Percutaneous closure of paraprosthetic regurgitation: clinical and echocardiographic analysis in high surgical risk patients - results and challenges

Arq. bras. cardiol; 121 (9 supl.1), 2024
INTRODUÇÃO O refluxo paraprotético (RPP) é uma complicação que afeta entre 1,9% e 17% dos pacientes submetidos à troca da valva mitral e em menor proporção, entre 2% e 12% dos casos de troca da valva aórtica, sendo mais comum em pacientes que recebem próteses mecânicas. Os pacientes que cursa...

Mulher jovem com agenesia total de pericárdio: relato de caso e revisão de literatura
Young woman with total pericardial agenesis: case report and literature review

Arq. bras. cardiol; 121 (9 supl.1), 2024
INTRODUÇÃO: A agenesia do pericárdio é uma patologia rara, com prevalência de 1:14.000 casos pela literatura. Seu diagnóstico é habitualmente incidental, visto que a maioria dos casos são assintomáticos. Pode ocorrer de forma total ou parcial, sendo três vezes mais prevalente entre indivíduos ...

Como eu faço o ecocardiograma para o diagnóstico de amiloidose
My Approach to Echocardiography for the Diagnosis of Amyloidosis

ABC., imagem cardiovasc; 37 (3), 2024
A amiloidose cardíaca (AC) é uma doença multissistêmica e infiltrativa, caracterizada pelo depósito de proteínas insolúveis conhecidas como fibrilas de amiloide no interstício (espaço extracelular) de diferentes tecidos, como coração, sistema nervoso, trato gastrointestinal e olhos. No coraç�...
