[Cardiogenic shock in the acute phase of myocardial infarction].

Cardiogenic shock (CC) is the most common cause of death in acute myocardial infarction (MI) and it has been often associated with fatal evolution. The aim of this study is to emphasize the positive impact of myocardial revascularisation especially percutaneous coronary angioplasty (PTCA) on short and mid term survival of 35 patients hospitalised for acute MI with CC. All the 11 patients who were on conventional therapy died, whereas the hospital mortality rate of the 24 patients who underwent primary PTCA was 41%. PTCA in CC complicating MI is highly effective and reduces the mortality rate in the literature from 80% to 40%. For this reason PTCA should be performed in each case of MI with CC seen in the first 6 hours.

[Contracted endocardial fibroelastosis in children: report of a case].

Endocardial fibroelastosis is un uncommon disease and it has a very bad prognosis since fatal evolution is usual before 2 years old. We report the case of a 20 years old woman who is affected with the contracted form of this disease associated with atrial septal defect (ASD) and mitral regurgitation. This disease was discovered by endocardial biopsy when she was 4 years old and underwent surgical resection of endocardial fibrosis, a patch on the ASD and mitral valve replacement. She was rehospitalised 15 years later with heart failure although continuous digitoxin therapy.

[Postpartum myocardial infarct (apropos of a case)].

We report the case of a 26 years old woman, who was hospitalized for an acute anterior myocardial infarction, which happened 17 days after delivery. The culprit lesion was a coronary dissection observed on the coronary angiogram which was performed on the 7th day. This dissection cicatrised spontaneously at the control coronarography performed 3 months later. Conventional medical treatment seems to be sufficient, although the use of thrombolysis in our case was safe and successful.

[Sinus node dysfunction after complete correction of tetralogy of Fallot. Report of a case].

Atrioventricular conduction defects after complete correction of tetralogy of Fallot are well known and their prevalence is decreasing with improved operative techniques. On the other hand, sinus node dysfunction has not been described after this type of surgery. The authors report the case of a 24 year old patient operated at the age of 2 for a favourable form of tetralogy of Fallot. In the long-term, this patient had a minimal anatomical sequel (mild pulmonary insufficiency) and first degree AVB with complete right bundle branch block with sinus bradycardia on the surface ECG. A recent aggravation of the patient's functional status led to rhythmological investigation which showed chronotropic atrial incompetence with nodal atrioventricular delay. The patient was implanted with a permanent DDD cardiac pacemaker programmed in the DDDR mode with a good outcome. Atrial chronotropic incompetence is one of the modes of expression of sinus node dysfunction. This has not been previously described in this context. This form of sinus node dysfunction should be systematically excluded after surgical cure of tetralogy of Fallot by exercise stress testing and 24 hour Holter ECG. Symptomatic patients are greatly improved by permanent cardiac pacing with hysteresis.

[Repolarisation anomalies simulating anterior myocardial infarction during ischemic cerebrovascular accident].

The authors report the case of a woman admitted to hospital for minor trauma of the left hip and who presented major ST segment elevation on the second day suggesting an acute anterior wall myocardial infarction at the same time as a cerebrovascular accident. Complementary investigations and follow-up excluded the diagnosis of myocardial infarction with normalisation of the ECG on the 5th day. ECG changes during cerebrovascular accidents may be very variable ranging from extrasystoles to ST elevation mimicking myocardial infarction. They carry a poor prognosis with an increased risk of sudden death necessitating continuous ECG monitoring until the ECG reverts to normal. The cardiac involvement is not ischaemic but due to disease of the insular cortex of the brain which induces myocytolysis (centered around the intra-cardiac nerve endings) due to the sudden liberation of catecholamines. These lesions may be treated by propranolol or phentolamine.

[Coxiella burnetti infectious endocarditis. Apropos of a case].

Chronic forms of Q fever (endocarditis) are rare, but are responsible for severe and desperately recurrent infections, resulting in multiple valve replacements with a reserved prognosis. The authors report the case of a 35-year-old patient with a known history of rheumatic fever, who developed blood culture negative infectious endocarditis on a mitral bioprosthesis. The diagnosis of Q fever was based on serological arguments. Despite long-term antibiotic therapy, serology remained strongly positive and was associated with repeated mitral valve disinsertion. The patient died immediately after the fourth operation in a context of haemodynamic failure. This clinical case emphasizes the importance of performing Q fever serology in any case of culture negative endocarditis and the therapeutic difficulties encountered in chronic recurrent endocarditis.

[Hydatid cyst of the heart of multivesicle type. Apropos of a case].

The authors report the case of a 30 year-old man on whom the diagnosis of hydatic cyst of the heart (HKC) was strongly suspected on bi-dimensional echocardiography and confirmed by surgery. This case is interesting because this HCH, completely latent clinically, was discovered by echocardiography performed in view of a localized infra-epicardic ischemia, the major contribution of bi-dimensional electrocardiography enabling to make a quick and easy anatomical and topographic diagnosis, the primary nature of this hydatic localization which does not affect any other organ, and finally the multivesicle aspect of the cyst, rather unusual in single localizations of hydatic cyst of the heart. A brief review of the literature is then presented.
