Sex-based outcomes after PCI in highbleeding risk patients: Results from the onyx one clear trial

Catheter. cardiovasc. interv; 97 (suppl. 1), 2021
BACKGROUND: While dual antiplatelet therapy (DAPT) constitutes the cornerstone of post-PCI pharmacotherapy, duration of DAPT in high bleeding risk (HBR) patients has not been fully defined especially with regard to sex. The results from the Onyx ONE Clear trial demonstrated favorable safety and efficacy ...

Artéria circunflexa com origem anômala em seio de valsalva direito em paciente idoso: relato de caso
Circumflex artery with anomalous origin in the right sinus of valsalva in an elderly patient: case report

INTRODUÇÃO: As anomalias coronárias congênitas são raras na população geral, com uma prevalência de 0,2 a 2,3%. Nos pacientes adultos a variante anatômica mais frequente é a artéria circunflexa (CX) anômala, tendo como possíveis origens o óstio separado dentro do seio coronário direito ou ...

Caso incomum de infarto agudo do miocárdio: embolia distal por grande aneurisma de tronco de coronária esquerda
Unusual case of acute myocardial infarction: distal embolism due to large aneurysm of the left main coronary artery

INTRODUÇÃO: Os aneurismas de artéria coronária (AAC) são definidos por uma dilatação focal de mais de uma vez e meia o segmento normal da artéria. São raros, sendo o aneurisma de tronco de coronária esquerda (TCE), ainda mais raro com incidência estimada em 0,1% dentre os pacientes submetidos ...

Modificando estratégias terapêuticas em pacientes em fila cirúrgica de revascularização do miocárdio baseado em novas evidências: decisão por Heart Team
Modifying therapeutic strategies in patients waiting for myocardial revascularization surgery based on new evidence: decision by Heart Team

INTRODUÇÃO: Novos fármacos e procedimentos percutâneos têm modificado a evolução da doença aterosclerótica coronariana. Estudos recentes demonstraram importantes modificações nas estratégias terapêuticas. Durante a pandemia de Covid-19 houve uma significativa redução dos procedimentos cirÃ...

Optical coherence tomography versus intravascular ultrasound and angiography to guide percutaneous coronary interventions: the iSIGHT Randomized Trial

BACKGROUND: Specific algorithms for use of optical coherence tomography (OCT) to guide percutaneous coronary intervention (PCI) are scarce. Also, the relative benefits of intravascular imaging guidance have not been tested against an optimized angiography-guided PCI strategy. In iSIGHT (Optical Coherence...

Coronary artery bypass surgery in patients with COVID-19: What have we learned ?

COVID-19 caused by the novel coronavirus SARS-CoV-2 led to the pandemic, causing unprecedented health and social crisis worldwide. Acute coronary syndromes patients, especially when coronary artery bypass graft (CABG) surgery is needed, may present with higher severity risk if affected by COVID-19. Extra...

Optimal medical therapy with or without surgical revascularization and long-term outcomes in ischemic cardiomyopathy

Objectives: Optimal medical therapy in patients with heart failure and coronary artery disease is associated with improved outcomes. However, whether this association is influenced by the performance of coronary artery bypass grafting is less well established. Thus, the aim of this study was to determine...

FANTOM II Trial: safety and performance study of the fantom sirolimus-eluting bioresorbable coronary scaffolddfirst report: 4-year clinical outcomes

J. Am. Coll. Cardiol; 76 (17 suppl. b), 2020
BACKGROUND The primary objective of the FANTOM II (Safety and Performance Study of the Fantom Sirolimus-Eluting Bioresorbable Coronary Scaffold) was to evaluate the safety and performance of native coronary artery stenting using the Fantom Sirolimus-Eluting Bioresorbable Coronary Scaffold by assessing th...

Desempenho diagnóstico da reserva de fluxo fracionado por tomografia na detecção de estenoses coronárias hemodinamicamente significativas

ABC., imagem cardiovasc; 33 (3), 2020
BACKGROUND: Coronary computed tomography angiography is a noninvasive anatomic test for the diagnosis of coronary artery disease. The coronary fractional flow reserve is the gold standard method to determine if coronary stenosis is hemodynamically significant but requires an invasive procedure. Fractiona...
