Evaluation of the mitral valve requires appreciation of its complex geometry. To accurately guide surgical interventions and describe pathology, three-dimensional transthoracic echocardiography (TTE) is an immense improvement over the cumbersome mental reconstruction required by two-dimensional approaches. Here we describe real-time, three-dimensional transthoracic techniques for assessing mitral regurgitation and mitral valve ...

Active phototropic bending of non-elongating and radially growing portion of stems (woody stems) has not been previously documented, whereas negative gravitropic bending is well known. We found phototropic bending in woody stems and searched for the underlying mechanism. We inclined 1-year-old Quercus crispula Blume seedlings and unilaterally illuminated them from ...

The natural history of aortic cuspal prolapse and aortic regurgitation (AR), studied most commonly in subpulmonic ventricular septal defect (VSD), has not been well defined in isolated, unrepaired VSD diagnosed during infancy. This study aimed to define the incidence and progression of aortic cuspal prolapse and AR in patients with ...

Aminoguanidine (AG), an inhibitor of advanced glycation endproducts, has been identified as a prominent agent that prevents the fructose-induced arterial stiffening in male Wistar rats. Our aims were to examine whether AG produced benefits on the left ventricular (LV)-arterial coupling in fructose-fed (FF) animals in terms of the ventricular and ...

Using stained acryl latex-injected techniques, the arterial circle of the brain in Acomys cahirinus Desmarest was studied. Results revealed an important individual variability of investigated structure. Three morphological variants were found: (1) the lack of typical arterial circle--opened in front and the back side, (2) partial opened at the back ...

To examine the association between MVP and Idiopathic Sudden Sensorineural Hearing loss (ISSNHL). 349 subjects, 86 with ISSNHL and 263 controls underwent a 2D-echocardiography. Patients with ISSNHL had higher rates of MVP (29.1% vs 2.7%, p<0.001), mitral leaflet thickening (15.1% vs 2.3%, p<0.001), mitral regurgitation (16.3% vs 6.5%, p=0.02) and ...

A variety of techniques has been used to repair prolapse of the commissure of the mitral valve. However, the application of these techniques may be technically challenging. A simple edge-to-edge suture approximation of anterior and posterior mitral leaflets is an effective way of restoring mitral valve competence. We use this ...

Cerebral Autosomal Dominant Arteriopathy with Subcortical infarcts and Leukoencephalopathy (CADASIL) is the most prominent known cause of inherited stroke and vascular dementia in human adult. The disease gene, NOTCH3, encodes a transmembrane receptor primarily expressed in arterial smooth muscle cells (SMC). Pathogenic mutations lead to an odd number of cysteine ...

Repair of the anterior mitral leaflet or bi-leaflet prolapse is technically more demanding than repair of the posterior mitral leaflet. Although several techniques have been proposed for the repair of anterior mitral leaflet prolapse during bi-leaflet repair, practical challenges remain, including the determination of the appropriate length for artificial chords. ...

Degenerative mitral valve disease is the most common cause of mitral regurgitation (MR) in developed countries. The most common etiologies of valvular regurgitation are Barlow's disease and fibroelastic deficiency. The mechanism of MR is type II dysfunction (leaflet prolapse) due to chordae elongation or rupture in most patients. Associated annular ...

BACKGROUND AND AIM OF THE STUDY: Successful mitral valve repair (MVP) is dependent on accurate annuloplasty band sizing. This is difficult and time-consuming when performed via port-access, or through a 4-cm minithoracotomy used in robotically assisted MVP. With the goal of moving toward a less-invasive approach and minimizing cross-clamp time, ...

Three-dimensional (3D) echocardiography (3DE) provides unique orientations of the mitral valve (MV) not obtainable by routine 2-dimensional echocardiography. However, this modality has not been adopted in routine clinical practice because of its cumbersome and time-consuming process. The recent introduction of a full matrix-array transducer has enabled online real-time 3DE (RT3DE) ...

We describe 3 cases of endocarditis after acute Q fever in 3 patients with clinically silent, undiagnosed valvulopathies, including mitral valve prolapse, minimal valvular leak, and biscuspid aortic valve. We conclude that, to prevent endocarditis, these minor valvulopathies must be actively searched for with echocardiography after diagnosis of acute Q ...

Overseas dispersals are often invoked when Southern Hemisphere terrestrial and freshwater organism phylogenies do not fit the sequence or timing of Gondwana fragmentation. We used dispersal-vicariance analyses and molecular timetrees to show that two species-rich frog groups, Microhylidae and Natatanura, display congruent patterns of spatial and temporal diversification among Gondwanan ...

A Hartwig-Buchwald addition of a variety of chiral amines to rac-4-bromo-[2.2]paracyclophane and rac-trifluoromethanesulfonic acid (4-[2.2]paracyclophane) ester was performed with high diastereoselectivities. Kinetic racemic resolution of the starting materials was achieved, providing a rapid access to enantiomerically enriched 4-bromo-[2.2]paracyclophane and the corresponding enantiomerically pure [2.2]paracyclophane amines. Additionally, the first reaction of ...
