[Congenital Valsalva sinus aneurysm opening into the right ventricle. Two operated cases]. / L'anévrisme congénital du sinus de Valsalva rompu dans le ventricule droit. A propos de deux cas opérés.

Congenital sinus of valsalva aneurysm is a rare cardiac lesion. Once the aneurysm has ruptured, a large left-to-right shunt is created. Prognosis is grave unless operative intervention is undertaken. The authors present 2 cases (2 male) of congenital aneurysm of the right sinus of valsalva ruptured into the right ventricle. The first patient (52 years) have a history of strenuous exertion followed by acute precordial pain and dyspnea. The second patient (25 years) was asymptomatic. The diagnostic was made by 2D and color doppler echocardiography. The defect was closed with a patch with good postoperative course. The authors emphasise the possible rupture of the congenital aneurysm of the sinus of valsalva after 50 years of age. Echocardiography is certainly the best method for diagnosing the condition and for following up these patients. The prognosis after surgical repair has usually been satisfactory.

[Percutaneous mitral commissurotomy: how can it be made simpler and more efficacious?]. / La commissurotomie mitrale percutanée: comment faire plus simple et plus efficace?

The authors report the results of a simplified method of percutaneous mitral dilatation from 936 procedures. This method introduced in our service since 1997 consists in progressively increasing diameters inflation of Inoué balloon, using echographic control and without any arterial procedure. Our population consists on 683 women (73%) and 253 men with a mean age 34 +/- 15 years (extremely 9 and 80 years) with subgroups composed of 26 pregnant women, 32 children less than 17 years, 59 restenosis after closed heart mitral commissurotomy, 14 restenosis after open heart mitral commissurotomy, 74 restenosis after percutaneous mitral commissurotomy, 5 tricuspid and mitral dilatation, 2 coronary and mitral dilatation (with stenting), 2 patients with a history of surgical mitral valvuloplasty for pure mitral regurgitation. The mitral area passed from 1 +/- 0.2 cm2 to 2.1 +/- 0.1 cm2. A surgical mitral regurgitation was observed in 3 cases. The time of fluoroscopy was 6.4 +/- 3.3 min. The hole time procedure was 19 +/- 9 min. The delay of hospitalisation was one day in 97% of patients. The decreased cost was about 20%. The patient comfort and the large diffusion of this method predicts a good future of this simplified technique.

[Percutaneous closure of ostium secundum atrial septal defect using an Amplazter device. Report of the first 5 Tunisian cases]. / Fermeture percutanee des communications interauriculaires ostium secundum par amplatzer. A propos des 5 premieres observations tunisiennes.

We report our initial expérience with percutaneous closure of ostium secundum atrial septal defect using Amplatzer device. Between september 2000 and july 2001, five devices were implanted in 5 patients, 4 female and 1 male. Age ranged from 18 to 66 years. A large atrial septal defect with significant shunting was diagnosed by trans thoracic echocardiography. Procedures were performed under general anesthesia with trans esophageal echocardiography guidance. Stretched diameter of atrial septal defects was determined by balloon sizing, ranged from 21 to 32 mm. Amplatzer devices of 20 to 32 mm were respectively deployed. No complications occurred during the procedure. Total occlusion of interatrial communication, was observed in one patient, immediately after the procedure, and in 3 patients 24 hours later. First 3 patients were controlled at months follow up were free of complications. Closure of atrial septal defect with Amplatzer device appears feasible and safe. However, long term results in comparison to surgery remain to be determined before definite conclusion regarding its use can be made.

[Evolution after 5 years of percutaneous pulmonary valvulotomy: report of 47 cases]. / Evolution a plus de 5 ans de la valvulotomie pulmonaire percutanée: a propos de 47 observations.

47 patients aged from 2 to 59 years affected by valvular congenital or mixed pulmonary stenosis including three fallot trilogies and one patient with right congestive cardiac failure are treated by percutaneous pulmonary valvulotomy between october 1986 and december 1990. All patients have been controlled with a mean follow-up of 6.5 +/- 1.1 years. The total gradient rate between pulmonary artery and right ventricule decrease from 112 +/- 55 mm Hg to 20 +/- 8 mm Hg on the last control with disappearance of infundibular inflammation and inter auricular shunt in all the concerned cases. We observe the regression of right cardiac failure symptoms with disappearance of tricuspid insufficiency in the cases of advanced pulmonary stenosis with right ventricular dysfunction. Percutaneous pulmonary valvulotomy by its simplicity and harmlessness, its long term efficiency is a good method of treatment of pure valvular or mixed pulmonary stenosis.

[Percutaneous mitral commissurotomy: simplified new method]. / La commissurotomie mitrale percutanée: nouvelle méthode simplifiée.

We report a new simplified method of mitral dilatation done on 146 patients. This technique use the Inoue balloon with progressive diameters under ultrasonographic control, avoiding the arterial part of the dilatation. The population include 9 pregnant women, 13 children, 13 with restenosis and closed heart and 12 restenosis after dilatation. Mean age is 32 +/- 16 years (9 to 72) and sex ratio 3.7 (114 F/32 M). Three groups are individualized according to histopathologic exam of mitral structure, group I (26%) concern good indication and III (32%) bad indication for this technique, group II (42%) contain intermediate indications. Commissurotomy increase the mean mitral square for 0.2 to 1.9 +/- 0.1 cm_. We observe 3 cases of chirurgical mitral insufficiency needing remplacement recruited for 2 patients from the group III. Mean fluoroscopic exposition time is 5.2 +/- 3.3 mn and procedure duration 18 +/- 11 mn. Hospitalisation duration is one day for 95% of the patients. This method remaining simple, efficient and safe permit a gain in time of 70% with a good comfort for patient and a return to work on the 4th day.
