Results were as follows: 1. Prolapse of the mitral valve (MV) was differentiated from systolic ballooning of the whole MV by the findings that the anterior leaflet's tip (rough zone) protruded into the left atrium with an acute angle between the body (clear zone) and rough zones of the anterior MV and that the posterior leaflet protruded markedly above the level of the mitral ring. 2. MR was detected in six patients (slight MR) by only the CD method and in 13 (mild, moderate or greater MR) by both the PCG and CD methods. 3. MR was absent or slight in five patients (three of pure MS and two of predominant MS) without valve thickening and with systolic ballooning of the whole valve due to commissural fusion. 4. Mitral valve abnormalities related to significant (mild, moderate or severe) MR were dependent on valve thickening (five patients), prolapse of the leaflet's tip toward the left atrium (four), or both (four). 5. An apical systolic click was found in only one of the nine patients with systolic ballooning, but in four of 11 with MVP. 6. The MR murmur in six of the nine patients with valve thickening showed the decrescendo or flat contour, but that in four of the eight patients with MVP showed a crescendo contour.

Between January 1974 and March 1989, 106 patients underwent isolated mitral valve replacement for mitral regurgitation. There were 54 male and 52 female patients ranging in age at operation from 22 to 76 years (average: 50.2 years). Mitral valve replacement with the Carpentier-Edwards bioprosthesis was performed in 55 patients and with the Björk-Shiley disc valve in 51 patients. The follow-up period ranged from four to 182 months with a mean of 64 months. There were three hospital deaths (2.8%). The actuarial survival including hospital deaths were 94.0% at five years and 89.3% at 10 years. The event-free rate was 75.5% at five years and 51.8% at 10 years. There was no significant differences in these results between two prosthetic valve groups. Because of high incidence of prosthetic valve-related events, mitral valve reconstruction for mitral regurgitation was performed in recent two years. Twenty patients had mitral reconstructive surgery. There were 11 male and nine female patients ranging in age at operation from 22 to 70 years (average: 54.4 years). Two had elongated chordae and 18 had torn chordae (anterior leaflet; four cases, posterior leaflet; 14 cases). There was no hospital and late death.

Case 1. A 40-year-old man visited our hospital in May 1982 to evaluate a heart murmur. A standard 12-lead electrocardiogram (ECG) showed an abnormal Q wave in lead III. Echocardiography revealed MVP, but neither dilatation nor wall motion abnormality of the left ventricle (LV) were observed. Thallium-201 scintigraphy revealed an abnormal thallium uptake at the apex and inferior wall. He had no episode of acute myocardial infarction or myocarditis, but complete right bundle branch block developed, thus, he was hospitalized in October 1984. He had no coronary artery lesions, and had only mild mitral regurgitation on left ventriculography. The motion of the interventricular septum and apex was reduced on echocardiogram and a persistent perfusion defect was observed at the inferior wall and the interventricular septum on Tl-201 scintigrams. In December 1985, he experienced an Adams-Stokes attack due to complete atrioventricular block. Echocardiographically, the left ventricle enlarged, and the wall motion abnormalities and a perfusion defect on Tl-201 scintigrams were relatively severe. Case 2. A 46-year-old woman occasionally experienced palpitation of short duration and chest oppression since 1977. She was admitted to our hospital because of cardiac symptoms in 1982. A heart murmur of Levine II was heard and a standard 12-lead ECG showed single supraventricular extrasystole and T wave inversion in lead III and aVF. Echocardiography revealed MVP and mild mitral regurgitation, but neither dilatation nor wall motion abnormality of the LV was observed. During 6-year follow-up period, permanent atrial fibrillation developed and LV developed dilatation and wall motion abnormalities progressed. Thus, during follow-up periods, DCM-like features developed in two cases who had had MVP as a sole echocardiographic abnormality with systolic murmur and non-specific ECG changes. We consider that these two may be important cases who may show a relation between cardiomyopathic process and MVP.</p>","PeriodicalId":77193,"journal":{"name":"Journal of cardiology.

To evaluate this systematically, we recorded 2-dimensional (2-D) and pulsed wave Doppler echocardiograms during acute mental stress in eight patients with MVP and eight age-matched normal subjects. Acute mental stress was administered by applying arithmetical task or reminding each patient of their most uncomfortable memories. Heart rate and blood pressure were significantly increased during mental stress and returned to the control level within a few minutes after its release in both groups. 2-D and Doppler echocardiograms were constantly recorded before, during and after acute mental stress. MVP was prominently augmented during mental stress in three of the eight patients. During mental stress, the mitral inflow velocity decreased in the rapid filling phase (R) and increased in the atrial filling phase (A), resulting in significant increase of the A/R in seven of the eight patients with MVP, especially in the patients associated with an increase of MVP. In normal subjects, mitral valve prolapse did not develop and the A/R was minimally increased or remained almost the same during mental stress. In conclusion, mental stress echocardiography seems to be a useful provocation test for the assessment of MVP and it is further expected to propose a lot of potential applications as a new method of stress echocardiography.</p>","PeriodicalId":77193,"journal":{"name":"Journal of cardiology.
