Background: Left atrial appendage closure (LAAC) was approved by the U.S. Food and Drug Administration (FDA) as a stroke prevention alternative to warfarin for patients with nonvalvular atrial fibrillation. However, clinical decision-making is confounded by the fact that although LAAC attenuates the anticoagulant-related lifetime risk of bleeding, implantation is associated with upfront complications. Thus, enthusiasm for LAAC as a treatment option has been appropriately tempered, particularly as the therapy is introduced beyond the clinical trial sites into general clinical practice.
Background: Valvular heart disease (VHD) and atrial fibrillation (AF) often coexist. Phase III trials comparing non–vitamin K antagonist oral anticoagulants (NOACs) with warfarin excluded patients with moderate/severe mitral stenosis or mechanical heart valves, but variably included patients with other VHD and valve surgeries.
Background: The use of non-vitamin K antagonist oral anticoagulants (NOACs) instead of vitamin K antagonists (VKAs) in patients with atrial fibrillation (AF) and coexisting valvular heart disease (VHD) is of substantial interest.
Background: The ICTUS (Invasive Versus Conservative Treatment in Unstable Coronary Syndromes) trial compared early invasive strategy with a selective invasive strategy in patients with non–ST-segment elevation acute coronary syndrome (NSTE-ACS) and an elevated cardiac troponin T. No long-term benefit of an early invasive strategy was found at 1 and 5 years.
Background: Left ventricular assist devices (LVADs) have been used as an effective therapeutic option in patients with advanced heart failure, either as a bridge to transplantation, as destination therapy, or in some patients, as a bridge to recovery.
Background: Transcatheter aortic valve replacement (TAVR) is being increasingly performed in patients with bicuspid aortic valve stenosis (AS).
Background: Pre-clinical trials have demonstrated that, during intravenous microbubble infusion, high mechanical index (HMI) impulses from a diagnostic ultrasound (DUS) transducer might restore epicardial and microvascular flow in acute ST-segment elevation myocardial infarction (STEMI).
Background: In patients with aortic stenosis undergoing transcatheter aortic valve replacement (TAVR), studies have suggested that reduced left ventricular (LV) ejection fraction (LVEF) and low aortic valve gradient (AVG) are associated with worse long-term outcomes. Because these conditions commonly coexist, the extent to which they are independently associated with outcomes after TAVR is unknown.
Background: Guidelines recommend surgery for patients with severe ischemic mitral regurgitation (MR). Nonrandomized studies suggest that subvalvular repair is associated with longer survival, but randomized studies are lacking.
Background: A direct comparison of outcomes between moderate mixed aortic valve disease (MAVD) and isolated aortic stenosis (AS) or aortic regurgitation (AR) has not been performed, making evidence-based recommendations difficult in patients with MAVD.
Background: Whether the rate of drug elution and polymer absorption affects clinical outcomes of biodegradable polymer-based drug-eluting stents (DES) is unknown. The widely used polylactide polymer-based Excel stent (JW Medical, Weihai, China) elutes sirolimus within 180 days, and the polylactide polymer is completely absorbed within 6 to 9 months. In contrast, the poly-lactide-co-glycolide polymer-based BuMA stent (Sino Medical, Tianjin, China) elutes sirolimus within 30 days, and the poly-lactide-co-glycolide polymer is completely absorbed within 3 months. Thus, both metallic DES elute sirolimus, isolating major differences to the polymer and elution kinetics.
Background: Dual-antiplatelet therapy with aspirin and clopidogrel after percutaneous coronary intervention reduces the risk for coronary thrombotic events (CTEs) at the expense of increasing risk for major bleeding (MB). Metrics to accurately predict the occurrence of each respective event and inform clinical decision making are lacking.
Background: In a prospective, multicenter, randomized controlled trial, 4,146 patients were randomized to receive standard care or standard care plus coronary computed tomography angiography (CCTA).
Tricuspid valve (TV) disease has been relatively neglected, despite the known association between severe tricuspid regurgitation (TR) and mortality. Few patients undergo isolated tricuspid surgery, which remains associated with high in-hospital mortality rates, particularly in patients with prior left-sided valve surgery. Patients with severe TR are often managed medically for years before TV repair or replacement. Current guidelines recommend TV repair in the presence of a dilated tricuspid annulus at the time of a left-sided valve surgical intervention, even if regurgitation is mild. This proposed algorithm aims to prevent the inevitable progression to severe TR and the need for a second surgical intervention. Recently, novel transcatheter treatment options were developed for treating patients with severe TR and right heart failure with prohibitive surgical risk. Here we describe currently available transcatheter treatment options for severe TR implanted at different levels: the junction between vena cavae and right atrium; the tricuspid annulus; or between TV leaflets, improving coaptation.
Background: The correlation between bicuspid aortic valve (BAV) disease and aortopathy is not fully defined.
