Balloon valvuloplasty for severe mitral valve stenosis in pregnancy. A report of 11 cases.

Balloon valvuloplasties for severe mitral stenosis were performed on 11 pregnant patients with excellent results and no complications. The mitral valve area was increased from a mean of 0.9 cm2 to 2.1 cm2. There was no clinically significant mitral regurgitation. The pregnancies proceeded normally to delivery at or near term, with no maternal or perinatal morbidity or mortality.

[Doppler echographic evaluation of mitral valve stenosis with atrial fibrillation. Construction of a nomogram].

Doppler echocardiographic evaluation of mitral stenosis is often difficult in patients with atrial fibrillation. Sixteen patients were examined by transthoracic Doppler echocardiography and the relation between the variations in transmitral end diastolic pressure gradient and the length of the corresponding cardiac cycles was analysed. Mitral valve surface area (1.65 +/- 0.73 cm2) was determined by the pressure half-time method. The end diastolic transmitral pressure gradient was calculated from the simplified Bernouilli formula applied to end diastolic mitral flow velocity. In each patient, a linear relationship was observed between the end diastolic mitral gradient and the corresponding RR interval. The slope and intercept of the graph correlated significantly to mitral valve surface area (r = 0.72, p < 0.002 and r = 0.93, p < 0.00001, respectively). Using regression equations describing these correlations, it has been possible to construct a nomogramme indicating mitral valve surface area as a function of mitral end diastolic pressure gradient and the duration of the corresponding RR cycle. This nomogramme facilitates Doppler evaluation of mitral stenosis in atrial fibrillation.

[Current approach to the surgical treatment of recurrent mitral valve stenosis].

In the period of 1971-1989, 266 patients with mitral restenosis were operated on: 82 closed mitral recomissurotomies and 184 operations under artificial circulation were performed. Complicated mitral diseases were found in 94% of the patients operated on. The causes of the mitral restenosis are analysed, and the features of its surgical correction together with the short- and long-term results are discussed. Comparison of the closed and open methods of the therapy for mitral stenosis showed that open-heart interventions under artificial circulation are most effective, prevent recurrences, and thus may be considered the operation of choice due to significantly lower hospital mortality rates in the recent five years.

[Severe cardiogenic hemolytic anemia with decreased flexibility of erythrocytes following surgical correction of mitral valve stenosis (author's transl)].

After surgical correction of a common atrium and closure of a mitral cleft, a mitral stenosis developed in a 5 year old girl. Postoperatively a pronounced hemolysis developed necessitating multiple blood transfusions. Rheologic measurements showed that hemolysis was due to a loss of erythrocyte deformability after mechanical damage. On the basis of these measurements it was concluded that the mitral stenosis was most likely responsible for this mechanical damage. Following another surgical correction of the mitral valve there was no hemolysis anymore.
