[Acute myocardial infarction revealing a pheochromocytoma: a case report]. / Infarctus du myocarde révélant un phéochromocytome : à propos d'un cas.

We report a case of a 38-year-old woman with pheochromocytoma admitted to our department for an acute myocardial infarction. The diagnosis of pheochromocytoma was evoked in view of the major pressure variations that appeared secondarily. Pheochromocytoma is mainly medullosurrenal tumour with clinical polymorphism; it can lead to severe cardiovascular disorders. Nevertheless, cardiac involvement is rarely in the foreground. Our clinical case illustrates the importance to evoke the diagnosis of pheochromocytoma in front of atypical manifestations of acute coronary syndrome so as to reduce mortality.

Percutaneous mitral valvuloplasty in patients with low cardiac output at high surgical risk.

Among 1146 patients undergoing percutaneous mitral valvuloplasty for symptomatic mitral stenosis, 8 (4 men and women) were at high risk for surgery on the basis of the New York Heart Association functional class IV (n=8), severe pulmonary hypertension (n=5). All these patients aged 30+/-23.6 years had signs of right heart failure, high echocardiographic score (9.6+/-3.6) and low mitral valve area (0.50+/-0.19 cm(2)). The procedure resulted in an increase in mitral valve area (1.55+/-0.17 cm(2)) with a concomitant reduction in pulmonary artery systolic pressure (58.7+/-9.9 mm Hg) and decrease in tricuspid regurgitation. At follow-up (mean 14+/-3 months), one patient with renal failure... presented with a mitral restenosis is scheduled for mitral valve replacement, two patients with severe tricuspid regurgitation required tricuspid annuloplasty. In conclusion, percutaneous mitral valvuloplasty is feasible and safe in patients at high surgical risk and can be considered as an acceptable alternative to surgery.

[Percutaneous mitral valvuloplasty in the pregnant woman Moroccan experience]. / Valvuloplastie mitrale percutanée chez la femme enceinte: expérience marocaine.

Pregnancy is one of the most important factors known to destabilize valvular heart disease. In particular, pregnancy is a major cause of aggravation in the clinical course of women with mitral stenosis (MS). Surgical treatment of MS during pregnancy may be hazardous for both mother and foetus. In this context, percutaneous mitral valvuloplasty using the Inoue balloon may constitute a particularly attractive alternative to surgery. We report the results of percutaneous mitral valvuloplasty achieved in a series of 11 pregnant women.

[Ruptures of the posterior wall of the left ventricle after mitral valve replacement: surgical repair and prevention]. / Les ruptures de la paroi postérieure du ventricule gauche après remplacement valvulaire mitral: réparation chirurgicale et prévention.

We report two cases of type III rupture of the left ventricle posterior wall, situated midway between the mitral annulus and the posterior papillary muscle and occurring in immediate continuations of a mitral valvular replacement. The first case has occurred at the moment of the canulas removal in a 28 years old patient operated for mitral stenosis. The tear was repaired with horizontal mattress sutures through felt strips on the external surface of the heart. The immediate post operative course was marked by bleeding recurrence and cardiac failure which has led to death. In the second case, a 68 years old man was operated for degenerative mitral insufficiency. The rupture has occurred just before closing the chest. The repair was realized successfully by using an intra-ventricular patch. The chordae tendinae removal constitutes a factor predisposing to the left ventricle posterior wall rupture. The repair has to use an intra-ventricular patch. The prevention is based on the preservation of the continuity between the mitral annulus and papillary muscles by preserving the sub-valvular apparatus or by using synthetic chordae.

[Arrhythmogenic right ventricular dysplasia. Report of 4 cases]. / La dysplasie ventriculaire droite arythmogene. A propos de 4 cas.

Arythmogenic right ventricular dysplasia (ARVD) was supposed to be a part of VHL diseases; ARVD is in fact a well defined anatomo-pathological entity, originally described by Fontaine and Frank in 1977. The authors report 4 new cases of ARVD were desmitted at the department of cardio A. The disease was announced by the usual rhythmic disorders. The diagnostics of ARVD was based upon a bundle of electrical, echocardiographic and histological arguments. The rhythmic stability was obtained in three cases with medical treatment, the endocavity ablation was necessary in one case. A study of the diagnostic and therapeutic forms is performed from a literature review.

[Mixed form of total anomalous pulmonary venous connection: apropos of a case]. / Forme mixte du retour veineux pulmonaire anormal total: a propos d'un cas.

As opposed to partial anomalous of pulmonary venous connection, it is frequent and benigns, the total anomalous of pulmonary venous connection is extremely rare and more serious. The anomalous is severe because all pulmonary venous connection, instead of left heart it go to the right heart. The age of diagnosis is closely tied up anatomics characteristics, so various clinical cases are present. The TAPVC of new born is a surgical emergency, especially where it's block up and release++ cardiorespiratory distress syndrome secondary to OAP. For great children, the total anomlous of pulmonary venous connection can be assumed to a case of atrial septal defect. This study intend to clear up this clinical and anatomical polymorphism and to report an exceptional-form of this congenital anomaly which is mixed total anomalous of pulmonary venous connection.
