The LV end-diastolic diameter (left ventricular end diastolic dia- meter; at the R wave of the electrocardiography) and the end-systolic diameter (LV end-systolic dimension; at the peak inward motion of the endocardial excursion) were recorded using the M-mode tracings of the level of the chordae tendinae at the end of expiration in the LV short axis view.
Moreover, circumferential detachment of the septal or anterior leaflets, longitudinal incision of the septal leaflet, subvalvular tricuspid apparatus detachment (chordae papillary muscle or both) from septum have all been described in prior reports examining the tricuspid valve dysfunction at short term follow up (11).
Impingement of the occluder on the valve leaflets may cause instant aortic or tricuspid regurgitation by interfering with the chordae tendineae17.
The mitral valve apparatus is composed of valve leaflets, mitral annulus, chordae tendineae (CT), papillary muscles, left ventricular and atrial walls (Figure 1).
Other alternative techniques, such as artificial chordae, chordal transfer, decalcification, papillary muscle (PPM) repositioning,[3] and sliding plasty, were also used to achieve one basic goal of restoring a smooth and correct-sized leaflet and creating the best coaptation area in the inflow of the left ventricle.
"Several strands of rope-like structures called chordae hold the valve, and are attached to papillary muscles that anchor them to the wall of the ventricle," Dr.
The prolapse of atrioventricular valves in the patients with Marfan Syndrome is thought to develop from fibromyxomateous changes in leaflets and chordae, abnormal annular distensibility, and possibly valve enlargement and calcification (Attias et al 2009; Malev et al 2014; Rybczynski et al 2011).
In uncontrolled hyperthyroidism, impaired collagen metabolism may lead to myxomatous leaflet and chordae degeneration, with subsequent MR [3, 4, 11, 12].
Intraoperatively, the tumor base was located at the leading edge of the anterior leaflet of the tricuspid valve, with some involvement of the chordae tendineae and the papillary muscles.
In the longitudinal section, some focal areas of widespread myocardiosclerosis were noted, but the integrity of papillary muscles and chordae tendineae was maintained.
They used an incision on the septal leaflet near anteroseptal commissure dividing tricuspid leaflet between attachments of chordae. Study was conducted over a period of 15 years.
The main drawback of standard flouroscopy is the inability to differentiate between the chordae tendineae and papillary muscles of the heart and other soft tissue structures in the area.
