Safety and efficacy of direct oral anticoagulants compared to Vitamin K antagonists postpercutaneous coronary interventions in patients with atrial fibrillation: A systematic review and meta‐analysis
Journal of Arrhythmia | January 9, 2020 | Volume: 36 | Issue: 2 | Pages: 271-279
AbstractBackgroundAtrial fibrillation (AF) and coronary artery disease (CAD) are commonly associated. Cotreatment with multiple antithrombotic agents can increase the risk of bleeding. We sought to evaluate patient‐centered outcomes in patients with AF on double therapy with direct oral anticoagulants (DOACs) compared to patients with standard triple therapy, [a vitamin K antagonist (VKA) plus dual antiplatelet therapy].MethodsWe performed a literature search of randomized controlled trials (RCTs) reporting outcomes of patients receiving double therapy with DOACs compared to triple therapy with VKAs in patients with AF undergoing percutaneous coronary intervention (PCI). Patient‐centered outcomes were the International Society of Thrombosis and Hemostasis (ISTH) major or clinically relevant nonmajor bleeding (CRNB), all‐cause mortality, major adverse cardiovascular events (MACE), stent thrombosis, myocardial infarction, and stroke.ResultsFour RCTs (9602 patients) met our inclusion criteria. Compared to VKAs, DOACs were associated with significantly lower ISTH major bleeding/ CRNB (RR: 0.75, 95% CI: 0.67‐0.82, P < .00001, I2 = 11%). There were no statistically significant differences in the efficacy outcomes, including myocardial infarction (RR: 0.99, 95% CI :0.79‐1.25, P = .96), stent thrombosis (RR: 0.97, 95% CI: 0.6‐1.55, P = .89), ischemic stroke (RR: 0.76, 95% CI: 0.5‐1.15, P = .19), all‐cause mortality (RR: 1.06, 95% CI: 0.85‐1.31, P = .61), and MACE (RR: 1.06, 95% CI: 0.91‐1.22, P = .97).ConclusionCompared with triple therapy with VKAS, double therapy with DOACs is associated with a reduced risk of bleeding and is as effective in patients with AF undergoing PCI.
A Coronary Conundrum: Papillary Muscle Rupture and Ischemic Mitral Regurgitation Secondary to Coronary Thromboembolism in Antiphospholipid Syndrome

Antiphospholipid syndrome (APS) is an autoimmune disorder that has a strong propensity for a hypercoagulable state and is known to be associated with venous and arterial thromboembolism. We describe an uncommon case of APS in the setting of non-Hodgkin’s lymphoma, with thromboembolism, and a rare complication after an uncommon etiology of myocardial infarction. This case highlights the importance of early and appropriate type of anticoagulation to reduce the morbidity and mortality in patients with APS.
Metastatic Neuroendocrine Tumor with Cardiac Involvement Utilizing Multi-Modality Imaging
Korean Circulation Journal | April 8, 2019 | Volume: 49 | Issue: 6 | Pages: 557
AbstractPatients with pectus excavatum (PE) frequently present with complaints of exercise intolerance and cardiopulmonary symptoms. There continues to be controversy regarding the physiologic benefits of repair. The aim of this review is to summarize and discuss recent data regarding the cardiopulmonary effects of PE deformity and the evidence for improvement obtained after surgical repair including (1) a greater efficiency of breathing (chest wall mechanics), (2) improvement in pulmonary restrictive deficits, (3) an increase in cardiac chamber size and output, with improved cardiac strain and strain rate, and (4) improvement in exercise capacity.
