milla1cf Thu, 03/28/2024 - 07:30 March 28, 2024 — Medtronic plc, a global leader in healthcare technology, announced that the United States Food and Drug Administration ( FDA ) has approved the Evolut FX+ transcatheter aortic valve replacement (TAVR) system for the treatment of symptomatic severe aortic stenosis. Aortic stenosis.
BackgroundOur previous preclinical study demonstrated thatAPOE4targeted replacement mice exhibit more severe cerebral hypoperfusion and cognitive impairment thanAPOE3targeted replacement mice with carotid artery stenosis due to neurovascular dysfunction.
The early detection of plaques by circulating biomarkers is highly clinically relevant to prevent the occurrence of major complications such as stroke or heart attacks. BackgroundAtherosclerosis is a widespread disorder of the cardiovascular system. EVs were isolated from serum by precipitation. EVs were isolated from serum by precipitation.
Circulation, Volume 150, Issue Suppl_1 , Page A4120743-A4120743, November 12, 2024. However, the most recurrent cardiac complication in RASopathies is pulmonary valve stenosis (PVS). Backgound:The RASopathies are developmental syndromes resulting from variants in the RAS/mitogen-activated protein (MAPK) cascade.
Circulation: Cardiovascular Interventions, Ahead of Print. Some patients with aortic stenosis may require multiple valve interventions in their lifetime, and choosing transcatheter aortic valve replacement (TAVR) as the initial intervention may be appealing to many.
Circulation: Cardiovascular Imaging, Ahead of Print. BACKGROUND:Patients with paradoxical low-flow, low-gradient severe aortic stenosis exhibit low transvalvular flow rate (Q), while maintaining preserved left ventricular ejection fraction. Subgroups were based on MR severity (severe and nonsevere).
Introduction:Moyamoya is a progressive cerebrovascular disease characterized by stenosis of the cerebral arteries in the anterior circulation and less often the posterior circulation. Children with moyamoya and basilar stenosis mentioned in their chart were initially included. In our cohort 7.2%
IntroductionIntracranial atherosclerotic disease (ICAD) is associated with up to 32% of posterior circulation strokes.1 Rescue treatment with stenting, balloon angioplasty, and/or intraarterial thrombolysis or antiplatelets are often required to treat the underlying stenosis.
Since the pathologist does not know the original cross-sectional area of the artery or the amount of compensatory enlargement of the artery from evaluation of a single cross section of the artery at a site of stenosis, the degree of luminal narrowing of that segment cannot be determined. These are typical findings at sites of plaque rupture.
Circulation, Ahead of Print. Background: Symptomatic severe aortic stenosis (AS) remains undertreated with high resultant mortality despite increased growth and availability of aortic valve replacement (AVR) since the advent of transcatheter therapies. cm2were enrolled.
PR was calculated as the ratio of proximal to distal pressure at the stenosis site, indicating post-stenosis blood flow. Arterial stenosis severity was categorized using the WASIDMethod:50%-69% for moderate and 70%-99% for severe. frequency was significantly higher in severe compared to moderate stenosis (P=0.01).
Our perspectives on aortic stenosis (AS) are changing. Novel approaches are developing to address this through: (1) screening with circulating biomarkers; (2) development of drugs to slow disease progression and (3) early valve intervention guided by medical imaging.
Circulation, Volume 150, Issue Suppl_1 , Page A4145373-A4145373, November 12, 2024. Background:There have been several studies postulating the association between Mitral valve stenosis (MS) and Chronic Kidney Disease (CKD). The prevalence of non rheumatic Mitral stenosis (MS) in the admission cohort was analyzed.
Introduction:Literature demonstrates that nearly one-third of acute ischemic stroke (AIS) patients with large vessel occlusion (LVO) or severe stenosis arrive at the emergency room with mild symptoms, attributed to favourable collateral status. Patients who underwent endovascular treatment before END were excluded. 1.22,22.18] P=0.026).Conclusions:Higher
Circulation: Cardiovascular Interventions, Ahead of Print. BACKGROUND:Current guidelines recommend surgical aortic valve replacement (SAVR) for patients with severe aortic stenosis and unfavorable iliofemoral access.
Circulation: Heart Failure, Ahead of Print. Background:Distinguishing hypertrophic cardiomyopathy (HCM) from other cardiomyopathies with left ventricular hypertrophy (LVH), such as hypertensive LVH, transthyretin amyloid cardiomyopathy (ATTR-CM), and aortic stenosis (AS), is sometimes challenging.
Circulation, Volume 150, Issue Suppl_1 , Page A4119619-A4119619, November 12, 2024. Background:Peak aortic valve Doppler velocity, mean aortic valve gradient, and Doppler estimated aortic valve area are key measures recommended for assessing aortic stenosis severity. Failure to accurately diagnose severe aortic stenosis is critical.
Previous studies suggest that the DHV sign was associated with early recurrent ischemic stroke in the anterior circulation secondary to intracranial atherosclerotic disease (ICAD). However, its significance in ischemic stroke in the posterior circulation is unknown.
Circulation: Cardiovascular Imaging, Volume 17, Issue 12 , Page e017425, December 1, 2024. BACKGROUND:In aortic stenosis, the myocardium responds with left ventricular hypertrophy, which is characterized by increased left ventricular mass due to cellular hypertrophy and extracellular matrix expansion. weeks post-AVR.
In a recent study published in Circulation , examined how diabetes influences outcomes in left main coronary revascularization procedures, specifically PCI versus CABG, is crucial for tailored treatment strategies. Circulation. Original article: Gaba P et al. 2024;149:00–00.
Circulation, Ahead of Print. Advances in cardiovascular imaging have improved the ability to identify coronary artery stenosis in patients with KD, yet knowledge gaps remain regarding optimal frequency of serial imaging and the best imaging modality to identify those at risk for inducible myocardial ischemia.
Steno-occlusive changes in the posterior cerebral arteries (PCAs) may contribute to worsened outcomes in patients with MMD; however, there is little information on the incidence and natural history of posterior circulation MMD (PCMMD).
Collectively, this study shows that Cleerly AI-QCT ISCHEMIA , when used in conjunction with Cleerly LABS, can provide a 3-in-1 approach for the assessment of atherosclerosis, stenosis and ischemia. Circulation. Gulati M, Levy PD, Mukherjee D, et al. 2021 Nov 30;144(22):e368-e454.
All participants underwent coronary computed tomography angiography (CCTA), a non-invasive imaging technique used to assess coronary artery anatomy and stenosis, at baseline and at 12 months. A total of 84 participants were enrolled, of which 72 completed the trial, with participants randomized to receive either colchicine 0.5
distal stenosis or occluded small branches), and 3) nonischemic causes for myocyte injury (e.g., The diagnosis of MINOCA should exclude: 1) other overt causes for elevated troponin (e.g., pulmonary embolism, sepsis, etc.), 2) overlooked obstructive coronary disease (e.g., myocarditis).
Circulation, Volume 150, Issue Suppl_1 , Page A4144277-A4144277, November 12, 2024. However, the long-term outcomes in patient with an intermediate stenosis received FFR have not yet been investigated comprehensively.Methods:We retrospective included 558 patients underwent both coronary artery angiography (CAG) and FFR.
BUT — Cardiac catheterization done a little later did not reveal any significant stenosis. Despite the absence of significant coronary stenosis on her post-arrest cath — the ECG in Figure-1 is clearly diagnostic of an extensive anterolateral STEMI ( presumably from acute LAD [ L eft A nterior D escending ] coronary artery occlusion).
Circulation, Ahead of Print. We focus on the most common primary valvular heart diseases, including calcific aortic stenosis, bicuspid aortic valves, mitral valve prolapse, and rheumatic heart disease, and outline the fundamental molecular discoveries contributing to each.
Circulation, Volume 150, Issue Suppl_1 , Page A4135852-A4135852, November 12, 2024. Background:Vertebrobasilar artery stenosis (VBAS) can cause posterior circulation strokes (PCS). Optimal management is controversial, with options including medical therapy (MT), endovascular stenting (ES), and surgical revascularization (SR).
Circulation: Cardiovascular Interventions, Ahead of Print. BACKGROUND:Data concerning the outcomes of transcatheter aortic valve replacement in type 0 bicuspid aortic stenosis (AS) are scarce.
