The concern of this approach is subvalvular obstruction, which may occur as a result of stagnant blood underneath the bioprosthetic valve (7, 11, 12).
Large oscillating masses were noted on the leaflets (the largest measuring 25 mm), extending to the subvalvular apparatus and periannular area (Fig.
The Doppler signals analyzed included continuous wave Doppler maximum pulmonary valve velocity, pulse wave Doppler subvalvular pulmonary velocity, and continuous wave Doppler tricuspid valve regurgitation (TR) velocity.
Examination of the left ventricular outflow tract revealed a subvalvular cavity in the anterior-basilar interventricular septum just below the left coronary cusp of the aortic valve (Figure 3,a).
We report about a rare congenital lesion of the subvalvular apparatus of the mitral valve which resulted in severe mitral regurgitation.
Mechanical complications such as injury to the tricuspid valve, subvalvular apparatus, knotting or entanglement in pacemaker wires occur in just under 1% (74).
The GDS Accucinch System is an innovative percutaneous device, placed through an artery in the patient's leg that cinches the subvalvular mitral annulus to reduce its size until the backward flow of blood through the mitral valve is corrected.
The presentation will report six major outcomes of an acute in vivo study of the TMVI system: (1) accurate positioning of the implanted valve relative to the mitral valve annulus; (2) secure anchoring of the implanted valve to the mitral anatomy without relying on radial force; (3) preservation of the subvalvular apparatus; (4) conformance of the implanted valve to the mitral annulus to prevent paravalvular leaks; (5) confirmation of a clear, unobstructed Left Ventricular Outflow Tract (LVOT); and, most importantly, (6) the successful delivery and deployment of the implant through an antegrade, transvenous, transseptal, catheter-based approach.
Inflammation, vagal stimulation, anoxia, and hemorrhagic diathesis could lead to sudden occlusion of small vascular channels and lead to subsequent hematoma formation in the subvalvular region.
Congenital heart defects that have been associated with UAPA are the followings; tetralogy of Fallot, ventricular septal defect (VSD), right aortic arch, truncus arteriosus, patent ductus arteriosus (PDA), CoA, subvalvular aortic stenosis, transposition of the great arteries and scimitar syndrome (2, 3, 5).
The SJM Quattro(TM) valve is a quadrileaflet (four leaflet) stentless mitral valve with full subvalvular apparatus integrated into the design.
Bavaria reported five major outcomes of the acute in vivo study of TMVI: (1) accurate positioning of the implanted valve relative to the mitral valve annulus; (2) secure anchoring of the implanted valve to the mitral anatomy without relying on radial force; (3) preservation of the subvalvular apparatus; (4) conformance of the implanted valve to the mitral annulus to prevent paravalvular leaks; and (5) confirmation of a clear, unobstructed Left Ventricular Outflow Tract (LVOT).
