“…Critical narrowing of the LVOT related to the stiffness of the MVR is reported as early and (rarely) late complications of valve pros thesis implantations in the mitral position or of mitral valvuloplasties [2,3,6], On the other hand systolic anterior move ment of the anterior mitral leaflet is known to be a potential cause of LVOT obstruction [7], In patients with isolated MVR calcifica tion, LVOT obstructions are occasionally re ported [5], but in these subjects mitral valve stenosis or insufficiency are more often found [8].…”

The pathophysiology, clinical presentation and prognosis of left-ventricular obstruction still represent an important cardiological problem. Various anatomical and/or functional mechanisms can cause this phenomenon. This report concerns 2 patients over 75 years old in whom the simultaneous presence of localized proximal septal hypertrophy and massive calcification in the anterior portion of the mitral valve ring provoked significant systolic intraventricular gradients. Cardiac rhythm disturbances and consequent variability of R-R intervals, found in both subjects, appear fundamental in determining the value of such gradients. Occasionally an anterior mitral ring calcification may bring about left-ventricular outflow tract obstruction in aged hearts where localized hypertrophy of the proximal portion of the intraventricular septum is present.

“…In some patients, the prosthesis reached the intraventricular septum, pro voking even lethal arrhythmias [8]. Obstruc tions along the left-ventricular outflow tract were observed also after Carpentier's mitral valvuloplasty [5][6][7] although Carpentier et al [13] do not report these complications in several patients treated with their tech nique.…”

The case presented is a 47-year-old woman with left-ventricular outflow tract obstruction which was the late complication of mitral valve replacement (4 years later). The diagnosis was made using two-dimensional Doppler echocardiography (echo-2D Doppler) and confirmed by cardiac catheterization. Protrusion of the prosthetic ring towards the intraventricular septum reducing the diameter of the outflow tract to 7-8 mm and creating a dynamic obstruction (30 mm Hg on cardiac catheterization, and 44 and 75 mm Hg on echo-2D Doppler basally and after isoamyl nitrite inhalation, respectively) was recorded. The echo-2D Doppler technique appears to be useful in detecting this postsurgical mitral complication.
