[Surgical correction of mitral valve stenosis and its recurrence].

The article analyses the results of surgical treatment of 1,394 patients with mitral stenosis who were operated on in the period between January 1, 1986 and April 1, 1989. Hospital mortality was 2.0%. Distinct indications for transventricular commissurotomy and mitral valve prosthetics were determined. The choice of the method for mitral stenosis correction was based on the character of the morphological changes in the cusps and subcuspal structures, which were determined during echocardiographic examination. With proper indications transventricular commissurotomy presents a small risk. Hospital mortality was 0.8% in mitral stenosis (among 1,039 patients who underwent operation 8 died) and 2.5% in recurrent stenosis (among 197 patients 5 died). Lethal outcomes were not encountered in stage 11, the mortality rate was 0.6% in stage III and 2.2% in stage IV. Mitral valve prosthetics was performed in 158 patients with 15 (9.5%) lethal outcomes. Hospital mortality was 4.5% in stage III and 10.3% in stage IV of the disease. In the group of patients with mitral stenosis hospital mortality was 7.5% (93 patients underwent operation). Hospital mortality after operations for recurrent mitral stenosis (65) was 12.3%. The initial severity of the patients' condition is still the main factor which influences unfavorably of the immediate results of mitral valve prosthetics.

Percutaneous transarterial balloon valvuloplasty for end-stage mitral valve stenosis.

A case of end-stage mitral stenosis is presented. Because of too high an operative risk surgical treatment was not advisable. Using an original technique, we performed the percutaneous transarterial balloon mitral valvotomy. The mitral diastolic pressure gradient was reduced after dilatation and there was no resultant mitral regurgitation.

[Functiono-morphological principles of classification of mitral valve stenosis].

By correlating the functional classification of mitral stenosis proposed by A.N. Bakulev and E.A. Damir with the myocardial changes detected on the ECG in 282 patients operated on for mitral stenosis, it has been established that the hypertrophic process in the right ventricle at Stage IV of heart disease corresponds to the stage of wearing off and progressive cardiosclerosis. Heart disease of Stage III is associated with morphological alterations in the left atrium and the right ventricle of various severity. In developing a surgical classification of heart disease it is necessary to consider electrographically evident morphological changes in the heart.

[Tetralogy of Fallot and mitral valve stenosis].

The association of tetralogy of Fallot and mitral stenosis is extremely rare. This is probably the first description of this association. The clinical and haemodynamic presentation is similar to that of cyanotic heart disease with pulmonary stenosis and post-capillary pulmonary hypertension. The mitral stenosis was probably congenital as it was diagnosed at 14 months of age.

[Oxidative phosphorylation in the myocardium of patients with mitral valve stenosis during surgery].

In 135 patients with mitral stenosis of the III and IV stages oxidative phosphorylation in the mitochondria of the left cardiac auricle was studied by the polarographic method. A uniform lowering of the mitochondrial respiration at different metabolic states with IV stage of the affection and in patiens of a more advanced age (36-52 years) was demonstrable. In some instances the conjugation of oxidation and phosphorylation was on a decline too. A nitrous oxide anesthesia (by comparison with the ether-oxygen one) produced a substantial depression of the mitochondrial respiration, especially when alpha-ketoglutarate was used. The sensitivity to the inhibitory effect of nitrous oxide in the elderly was higher. Respiration with succinate as a substrate in the young (20-35 years) patients proved little sensitive to the suppressing action of this type of anesthesia.

Intraoperative measurement of the orifice area in patients with mitral valve stenosis.

This study was carried out in ten patients in order to compare results of mitral valve area evaluated by a new intraoperative technique and those provided by conventional hemodynamic methods. The results obtained correlated very well (r = 0.95) with values calculated by the Gorlin formula. Paired data checking were closer than 0.3 cm2 in all but one of patients with moderately severe mitral stenosis. It is concluded that the method for intraoperative measurement of the mitral valve area is simple, safe and reliable.

[Results of surgery for mitral valve stenosis].

Long-term follow-up of 1806 patients si subjected to mitral commisurotomy and 122 fitted with a prosthesis for stenosis is described. Of those operated by means of the closed technique, 70% were in functional stage I or II after 10 yr (55% after 15 yr). It would seem from these results that surgery has an important effect on the natural history of mitral stenosis when treated solely medically.

[Percutaneous mitral commissurotomy in patients with mitral valve stenosis and thrombosis of the left atrium].

UNLABELLED: Mitral percutaneous valvotomy (MPV) is an effective therapeutic alternative in the treatment of patients with mitral stenosis (MS) and thrombus in the left atrium have been an absolute contraindication to this procedure. The aim of our study is to evaluate the safety of MPV in patients with MS and thrombus in the appendix of the left atrium (ALA). Between September 1996 and April 1997, we performed ten procedures of MPV with Inoue's technique in patients with MS and thrombus in ALA. Nine females and 1 male were included. Their were 41 +/- 7.6 years old. The Wilkins score in our patients were 8 +/- 1.2. All were treated with oral anticoagulants between three and twelve months but the thrombus did not resolved. With transesophagic echocardiogram and fluoroscopic control we avoided the contact between wires and Inoue's catheter with ALA. Results were positive. Mitral valve area increased from 0.8 +/- 0.2 cm2 to 1.95 +/- 0.3 cm2. There was no case of systemic embolism or others major complications during the MVP and during following one year. CONCLUSION: MPV is a safe and efficient therapeutic alternative in the treatment of selected patients with MS and thrombus in ALA.
