Asen Petrov, Abdel‐Hannan Diab, Ali Taghizadeh‐Waghefi, Manuel Wilbring, more

Journal of Cardiac Surgery > 37 > 7 > 2202 - 2204

Treatment of infective endocarditis can often prove challenging due to its wide range of anatomical presentations. When complicated by an aortic root abscess, patients may require extensive root surgery, which on its own leads to a worse outcome. We present our experience with a surgical technique for reinforcing the aortic annulus with a ring from a Dacron aortic prosthesis placed in the left ventricular...

Right Ventricular Reduction as an Adjunct Procedure in Tricuspid Valve Repair

Utz Kappert, Sems-Malte Tugtekin, Ahmed Ouda, Konstantin Alexiou, more

The Annals of Thoracic Surgery > 2008 > 85 > 5 > e27-e29

Functional tricuspid regurgitation secondary to mitral valve disease can not be attributed to the dilatation of the tricuspid annulus alone. Furthermore, geometrical changes of the right ventricle lead to tethering of the tricuspid valve leaflets and thereby to an incomplete leaflet coaptation. With this pathologic entity, conventional isolated tricuspid valve annuloplasty will presumably result in...
