Mitral-aortic annular enlargement: modification of Manouguian's technique

Aortic Annular Enlargement during Aortic Valve Replacement

In the surgery of aortic valve replacement is always attempted, as much as possible, to implant the larger prosthesis with the mains goals to enhance the potential benefits, to minimise transvalvular gradient, decrease left ventricular size and avoid the phenomenon of patient-prosthesis mismatch. Implantation of an ideal prosthesis often it is not possible, due to a small aortic annulus. A vari...

Mitral annular kinetics in mitral regurgitation

Methods Population: Patients with degenerative mitral regurgitation (n = 35) with normal LV EF pre and 12 months post mitral valve repair. Normal volunteers (n = 51). Image Acquisition: All participants underwent MRI on a 1.5T scanner (GE Healthcare) optimized for cardiac application. An ECG-gated, breath-hold steady state free precision technique was used to obtain 2 chamber and 4 chamber view...

Large Caseous Mitral Annular Calcification

A 68-year-old woman presented with exertional dyspnea, angina, and syncope. She was undergoing renal dialysis (3 times weekly, for one year) and was taking nifedipine for hypertension. Laboratory results suggested secondary hyperparathyroidism and hypercalcemia. Auscultation revealed a severe systolic murmur at the left upper parasternal border and a moderate diastolic murmur at the cardiac ape...

Aortic Valve Annular Sizing

Impact of Mitral Annular Displacement on Left Ventricular Diastolic Function Improvement After Transcatheter Aortic Valve Implantation.

BACKGROUND The clinical significance of left ventricular (LV) diastolic function (DF) improvement after transcatheter aortic valve implantation (TAVI) is not fully elucidated. We sought to investigate the long-term clinical and hemodynamic effects of post-TAVI DF improvement and to identify its determinants.Methods and Results:Clinical and serial echocardiographic data before and after TAVI wer...
