Background Bicuspid aortic valve (BAV) is the most common congenital heart defect in adults, often leading to complications such as thoracic aortic aneurysms and aortic stenosis. While BAV is frequently associated with 22q11.2
Douglas Weaver MD, MACC discuss the history of and complications associated with bicuspid valvuloaortopathy. In this interview, Hector I. Michelena, MD, FACC and W.
1, 2024 — Researchers at UTHealth Houston have identified genetic variants linked to a rare form of bicuspid aortic valve disease that affects young adults and can lead to dangerous and potentially life-threatening aortic complications. tim.hodson Wed, 09/04/2024 - 15:53 Sept.
Windsock deformities, though rare, represent a severe form of valvular aneurysm distinguished by localized balloon-like protrusions of the leaflet body. Here, we present a compelling case of windsock mitral va.
Introduction:Mitral annular disjunction (MAD) is an abnormality of the mitral valve where a portion of the mitral annulus and valve leaflets insert into the left atrium away from the fibrous annulus. The scar and aneurysm that develop can serve as substrate for reentrant VA. cm SMA on the basal inferior and inferolateral walls.
Aortopathy encompasses a spectrum of conditions predisposing to dilation, aneurysm, dissection, or rupture of the aorta and other blood vessels. Pathogeneses include connective tissue disorders, smooth muscle contraction disorders, and congenital heart disease, including bicuspid aortic valve, among others. Circulation, Ahead of Print.
This could result from abnormalities in NCC migration, differentiation, or proliferation leading to structural abnormalities and are attributed to genetic, familial, sporadic or acquired causes.DiscussionPhenotypic characteristics of cardiovascular neurocristopathies, such as bicuspid aortic valve and thoracic aortic aneurysm, share a common embryonic (..)
Mitral Valve Repair and Replacement: If the mitral valve, which can be found between the heart’s left atrium and left ventricle, is unable to function properly, its flaps thicken or stiff, and oftentimes fuse together. Transcatheter Edge-to-Edge Repair (TEER): TEER focuses on the mitral valve.
Of course, papillary muscle rupture and mitral regurgitation should be on the differential here, as in this case , but it is not very likely when the BP is so high. Inferior LV "aneurysm" morphology Electrocardiographic "LV Aneurysm" morphology simply means "persistent ST elevation after previous MI." Is this acute STEMI?
Many genes in the identified pathways were previously reported in genome‐wide association studies for aneurysm, bicuspid aortic valve, or aortic size.ConclusionsSmaller sample sizes in rare disease studies necessitate new approaches to detect modifiers. Two implicated matrisome genes (ACANandLTBP4) were uniquely expressed in the aorta.
Mitral valve leaflets seen in open position between the left ventricle and left atrium are thickened. The large aortic regurgitation jet can be seen as a mosaic jet in the left ventricular outflow tract anterior to the anterior mitral leaflet. Thickening of both aortic and mitral leaflets indicate the possible etiology as rheumatic.
We present a case of subarachnoid hemorrhage (SAH) due to SCS lead migration into the subdural space.MethodsAn 81‐year‐old female patient with a past medical history of heart failure, atrial fibrillation and a mechanical mitral valve, presents with a severe headache and right hemiparesis.
Kawasaki Disease Case : Angela Khidhir, DO, MSc (USA) presented a compelling case on ACS and tamponade potentially linked to Kawasaki disease-related Coronary Artery Aneurysm. This debate underscored the growing role of CSP despite the current limited evidence supporting it.
The post ectopic increase in the murmur is a hallmark of hypertrophic obstructive cardiomyopathy, which differentiates it clinically from mitral valve prolapse. Echocardiography in HCM Important echocardiographic features include mitral regurgitation and left ventricular outflow tract obstruction.
She had a history of PCI to the circumflex and also of severe mitral regurgitation, status post bioprosthetic valve replacement. Also a h/o LV aneurysm with thrombus, on anticoagulation, as well as a dual chamber pacemaker. Aneurysm of the mid-portion of the lateral and inferolateral wall. They called 911.
For example, mid-anterolateral and mid-inferior segments generally harbor papillary muscles and infarction of these segments may result in acute mitral regurgitation due to papillary muscle dysfunction or rupture. These being said, the most important thing in this clinical situation is to diagnose OMI, whatever you call it.
By these mechanisms, SMC-MR promotes disease progression in models of aging-associated vascular stiffness, vascular calcification, mitral and aortic valve disease, pulmonary hypertension, and heart failure. While rarely tested, when sexes were compared, the mechanisms of SMC-MR-mediated disease were sexually dimorphic.
A 50-year-old female patient presented with a dumbbell giant right coronary artery ectasia, characterized by two artery dilation segments both reaching the level of a giant aneurysm with a normal segment between them. She felt relieved after successful coronary artery fistula repair, mitral valvuloplasty, and fistula sac removal.
When there are QS-waves, one should always think about LV aneurysm, but ST to QRS ratio and T-wave to QRS ratio are far too large and not compatible with left ventricular aneurysm. There is some R wave in the lateral precordial leads. Leads V3 and V4 both have 6mm ST elevation. This ECG shows a lot of "acuity".
There are no Q-waves to suggest old inferior MI, or inferior aneurysm as the etiology of the ST Elevation. The scan showed a bicuspid aortic valve with severe stenosis and coronary artery disease. However, there is also significant tachycardia , with heart rate of 116, and known hypoxia.
