[Acute coronary syndromes in patients treated with HIV protease inhibitors]. / Les inhibiteurs de la protéase du VIH favorisent-ils la survenue de syndromes coronaires aigus?

INTRODUCTION: Cardiovascular complications occurring in patients infected by the human immunodeficient virus (HIV) have considerably changed since the appearance, in April 1996, of highly active antiretroviral tri-therapy (HAART), associating reverse transcriptase and protease HIV-1 inhibitors. The spectacular efficacy of anti-proteases has led to the almost complete disappearance of these opportunistic complications. However, in May 1998, acute coronary accidents were reported in the literature, thus questioning the possible responsibility of antiprotease treatment in the occurrence of accelerated atheroma. METHOD: We report a series of 8 seropositive patients in whom an acute coronary event had occurred between February 1997 and February 1999. RESULTS: The patients were young and all exhibited cardiovascular risk factors (smoking, dyslipidemia) and were treated with HIV-1 protease inhibitors. Six patients presented myocardial infarction, one patient unstable angina and one patient effort angina. COMMENTS: A rise in triglycerides was observed principally on ingestion of ritonavir and a rise in cholesterol and LDL-cholesterol with all the antiprotease agents. Glucose intolerance was observed with indinavir. The occurrence of acute coronary events appeared to be related to antiprotease treatment (at the origin of metabolic disorders, endothelial dysfunction...), although it was impossible to say whether the antiprotease agents were responsible for the early atheroma or whether they simply contributed to the event. The coronary lesions were characterized by their number (single artery) and their topography (proximal or median). Nelfinavir may carry less cardiovascular risks than the other antiproteases. Mean term prognosis was relatively good, after therapeutic adjustment (change in antiprotease, strategic measures against cardiovascular risk factors, introduction of anti-anginal treatment...). CONCLUSION: Larger and longer studies would help to specify the role of antiproteases in the occurrence of early coronary events. Rigorous monitoring (lipid and glucose measurements, tests to search for myocardial infarction,..) together with the development of new antiretroviral molecules would reduce the number of coronary events in this type of patient.

[Cardiac side effects of anti-HIV agents]. / Complications cardiaques des médicaments au cours de l'infection par le VIH.

Both nature and prognosis of cardiac complications occurring in patients infected by the Human Immunodeficiency Virus-1 (HIV-1) have changed considerably since the introduction of highly acive and anti-retroviral triple therapy ("HART"). Opportunist cardiac infections have thus been displaced and side effects of drugs now occupy the primary aetiological role. Torsades de pointe may be exceptionally triggered by anti-infectious agents such as pentacarinat or trimethoprime-sulfamethoxazole, as are those induced by the association of ketoconazole and terfenadine or cisapride, the dangers of which are well known and the prevention more effective, especially with the association with HIV antiproteases which inhibit the cytochrome P450. The diagnosis of iatrogenic myocardial dysfunction is more difficult, except when it occurs acutely as with phosphonoformate (Foscarnet), or interleukine-2. Progressive cardiomyopathy caused by -interferon and dideoxynucleosides (zidovudine, didanosine and zalcitabine), reversible on withdrawal of the drug responsible in half the cases, should be distinguished from those due to the HIV itself (therapeutic relay) or to another associated cause (alcohol, coronary artery disease). The coronary complications of diseases treated by antiproteases usually occur in smokers whose cholesterol and triglyceride levels are rapidly increased with HAART. In a series of 9 patients (amongst 700 treated with the antiproteases), after the acute phase of myocardial infarction during which the interventional approach is often preferred, the medium-term prognosis is relatively good, on condition that the patients correct the hyperlipidaemia and give up smoking.

Recurrent subcutaneous infection due to Scopulariopsis brevicaulis in a liver transplant recipient.

We describe a case of recurrent Scopulariopsis brevicaulis subcutaneous infection, which occurred 6 years after the patient underwent liver transplantation. Combined surgery and long-term oral therapy with terbinafine resulted in a favorable outcome, although this is not the rule in the previously reported S. brevicaulis infections in immunocompromised patients.

[Cardiac tamponade]. / Tamponnade.

Cardiac tamponade is an emergency situation. Diagnosis is to be suspected when an elevation of systemic venous pressure, a decline in systemic arterial pressure and a clinical context of neoplasia or recent acute pericarditis are associated. Transthoracic echocardiogram is the gold-standard of diagnosis, and allows the accurate diagnosis of a large pericardial effusion: precise localisation and haemodynamic evaluation are needed before therapeutic decision. Pericardiocentesis is the only appropriate treatment. Surgical procedure, or less traumatic echo-guided pericardiocentesis, provide rapid haemodynamic relief of symptoms. Prognosis is determined by aetiology.

Subxiphoid pericardiocentesis guided by contrast two-dimensional echocardiography in cardiac tamponade: experience of 110 consecutive patients.

AIMS: We evaluated echo-guided pericardiocentesis with contrast study in cardiac tamponade management. PATIENTS AND METHODS: From 1982 to 1998 we performed pericardiocentesis in 110 patients (56 +/- 14 years old). Subxiphoid approach was used in 109. Cardiac tamponade was idiopathic (n = 16), secondary to malignant disease (n = 50) and miscellaneous disorders (n = 44). RESULTS: Pericardial fluid was bloody (n=75), serous (n = 29) or turbid (n = 6). Mean volume of fluid removed was 585 +/- 370 ml. When prolonged drainage (60 +/- 26 h) was used (n = 41), total effusion volume was 850 +/- 340 ml. Eleven deaths were observed during the early period following pericardiocentesis. No relation with procedure was demonstrated by autopsy in 10, and death always occurred in critically-ill patients (five malignant diseases, five cardiac ruptures and one septic shock). Other complications were: right ventricular puncture (n = 11) with deleterious effect in one, vasovagal hypotension (n = 6) and paroxysmal arrhythmia (n = 6). Surgical drainage was mandatory in 19 patients. It had to be done as an emergency (within 6 h), because of failure of the procedure in four patients. In 14 patients without prolonged drainage a delayed surgical evacuation was indicated, because of persistent (n = 3) or recurrent (n = 11) cardiac tamponade. Only one surgical procedure was required after prolonged drainage. CONCLUSIONS: Echo-guided pericardiocentesis with contrast study is an effective technique which reduces the risk of cardiac tamponade management. It should be considered in patients with critical haemodynamic condition or advanced malignancy, and in patients with poor short-term prognosis.

Intrathoracic gossypiboma: magnetic resonance features.

Gossypiboma, a term used to describe a mass within the body composed of a cotton matrix which usually refers to a retained surgical sponge, is a rare complication of cardiac surgery. We report one case revealed by the recurrence of the anginal symptoms after successful myocardial revascularisation surgery. The preoperative diagnosis was suspected by a combination of imaging techniques and subsequently confirmed by surgical removal. We review the literature to summarise the diagnostic and therapeutic features of gossypibomas.

Pericarditis associated with longstanding mesalazine administration in a patient.

An adult male patient was admitted for a pericardial effusion occurring during a longstanding mesalazine treatment for Crohn's disease. The relation between the drug's administration, symptoms and ECG changes suggests that the pericardial injury was caused by mesalazine. Also, the rapid resolution of clinical signs and ECG changes following the drug withdrawal were in agreement with this hypothesis. Eight months later, the patient remains well and symptom-free, and ECG and echocardiographic control were normal.

[Tamponade in patients with systolic left ventricular dysfunction. An atypical presentation]. / Tamponnade chez des sujets atteints d'une dysfonction ventriculaire gauche systolique. Une présentation atypique.

BACKGROUND: Left ventricular failure has been described following surgery due to localized compression of the left ventricle and in case of diastolic left ventricular dysfunction after pericardiotomy or pericardiocentesis. CASE REPORTS: Global heart failure was observed in 3 patients with dilated cardiopathy who developed tamponade. Systolic left ventricular dysfunction was caused by ischemic heart disease in one patient and secondary to anthracyclin chemotherapy in the two others. The effusion was successfully removed with pericardiocentesis in all three cases. No specific complications were observed. DISCUSSION: Although exceptional, tamponade may occur in patients with signs of left ventricular failure.

[Evaluation of echo-guided pericardiocentesis in cardiac tamponade]. / Evaluation de la péricardiocentèse écho-guidée lors de la tamponnade.

Between April 1982 and December 1995, 78 consecutive patients with an average age of 57 +/- 13 years underwent echo-guided pericardiocentesis in the intensive care unit for poorly tolerated pericardial effusions. The patients were admitted to the cardiology departments of Ambroise-Paré Hospital at Boulogne (n = 44). Gilles-de-Corbeil Hospital at Corbeil-Essonnes (n = 31) and Val-de-Grâce Hospital in Paris (n = 3). The underlying aetiologies were malignant disease (n = 31), idiopathic (n = 13), post-surgery (n = 7), infection (n = 7), autoimmune (n = 6), post-radiotherapy (n = 6), post-myocardial infarction (n = 3), chronic renal failure (n = 3) and coagulation defects (n = 2). Pericardial puncture was undertaken by the subxiphoid (n = 77) or left parasternal (n = 1) approaches under guidance of echocardiography. Intra-pericardial contrast was used to verify the position of the catheter. The average volume of liquid drained was 580 +/- 390 mL. After pericardiocentesis, continuous drainage was continued in 17 patients for an average duration of 63 +/- 29 hours. The total average volume was 750 +/- 330 mL. The major complications were a) three deaths during the puncture, not caused by the procedure after post-mortem study, b) ten right ventricular punctures with no consequences in 9 cases, c) two cases of shock, one of which was due to a pre-existing septicaemia of pulmonary origin, d) two non-sustained ventricular arrhythmias. The minor incidents were six vasovagal syndromes during the procedure and four paroxysmal supraventricular arrhythmias. Emergency surgical drainage was required (n = 3) for a failed procedure and late surgical drainage (n = 12) for persistence or recurrence of the effusion. No surgical drainage was required in the 17 patients placed under continuous aspiration. Echo-guided pericardiocentesis is a simple procedure and provides rapid haemodynamic relief in subjects generally in serious condition. Continuous aspiration may help avoid the need for surgical drainage for persistence or recurrence of the effusion.

[Ultrasound-guided pericardial drainage. Experience in 34 consecutive patients]. / Drainage péricardique écho-guidé. Expérience chez 34 patients consécutifs.

OBJECTIVES: Transthoracic echoguided puncture of the pericardium can be an alternative to surgical drainage. We report our experience with this technique acquired over the last 11 years. PATIENTS AND METHODS: From January 1984 to September 1995, 34 consecutive patients in the cardiology intensive care unit (mean age 56.5 +/- 13 years) underwent echoguided pericardial puncture for poorly tolerated pericardial effusion. The underlying cause was neoplasia (n = 22), idiopathic disease (n = 5), autoimmune disease (n = 2), post-surgical complication (n = 2 including 1 on hemodialysis), infection (n = 1), antivitamin K therapy (n = 1) and disseminated vascular coagulation (n = 1). The subxyphoid (n = 33) or left parasternal (n = 1) route was used under echographic guidance. Intrapericardial contrast allowed verification of the catheter position. The mean quantity of fluid removed was 585 +/- 390 ml. The fluid was hemorrhagic (n = 19), clear (n = 10) or serohematic (n = 4). Aspiration was continued in 16 patients after the initial puncture for a mean 64 hours. The mean total volume of fluid was 750 +/- 330 ml. RESULTS: There was one death during puncture which was found to be unrelated to the procedure after anatomic verification. In two cases, the left ventride was punctured without any consequence. Collapsus occurred during puncture in 2 patients with pulmonary sepsis. Minor incidents were: 6 vasovagal syndromes at puncture with paroxysmal supraventricular rhythm disorder during aspiration. Prior to 1988, surgical drainage was required in 5 patients for persistent or recurrent effusion. Since that time, continuous aspiration has been used in all patients and no surgical drainage has been required. Short-term prognosis depends on the underlying cause (6 deaths at 1 month). CONCLUSION: Echoguided pericardial puncture is a simple procedure which rapidly improves cardiac hemodynamics in these particularly fracle patients. Continuous aspiration avoids subsequent surgical drainage for persistent or recurrent effusion.

[Outcome of traumatic tricuspid insufficiency, treated surgically. Apropos of 9 cases]. / Devenir de l'insuffisance tricuspide traumatique opérée. A propos de neuf cas.

Between 1983 and 1992, 9 patients with traumatic tricuspid regurgitation underwent surgical correction. The population consisted of young male adults (mean age 39 years). The trauma was usually due to a road traffic accident (n = 6). The mean interval to diagnosis was long (11 years). Echocardiography was diagnostic and showed the mechanisms. The usual lesion observed at surgery was subvalvular rupture of the anterior papillary muscle (n = 5). Surgery consisted of valve repair with annuloplasty and eight valve replacements for chronic retractile lesions. Six patients are still being followed up (average 7 years). There were no peroperative complications. Two patients underwent a second valve replacement for degeneration of a bioprothesis. Conduction defects requiring permanent cardiac pacing were not uncommon (n = 3) The delay before diagnosis may be explained by the diversity of lesion of the tricuspid valve, associated cardiac disease and the requesting of echocardiography. Surgical indications are mainly based on clinical signs. Even if long-term results are satisfactory, earlier diagnosis would probably allow more conservative surgery with preservation of right ventricular geometry and function.

[Pleuropericarditis complicated of tamponade disclosing mixed connective tissue disease. Remission with non-steroidal anti-inflammatory agents. Apropos of a case]. / Pleuropéricardite compliquée d'une tamponnade révélatrice d'une connectivite mixte. Régression sous anti-inflammatoires non stéroïdiens. A propos d'un cas.

Mixed connective tissue diseases or Sharp's syndrome are inflammatory diseases essentially presenting in the form of joint, muscle and skin manifestations. Pleuropericardial involvement is uncommon and rarely the presenting sign, and tamponade is exceptional. This clinical report concerns a case of pleuropericarditis complicated by tamponade in a 22-year-old man, constituting the presenting sign of Sharp's syndrome. The diagnosis of mixed connective tissue disease was based on the combination of clinical signs and a high serum anti-RNP antinuclear antibody titre. The treatment of the pericarditis is base on prescription of corticosteroids, but non-steroidal anti-inflammatory drugs were sufficient in our case. Larger effusions may require corticosteroids and pericardial drainage. We report the value of immunological assays in the aetiological assessment of pleuropericarditis in young subjects.

[Traumatic tricuspid insufficiency]. / L'insuffisance tricuspide traumatique.

Traumatic tricuspid insufficiency is a rare condition. The diagnosis is difficult because of the slow progression of this pathology and the presence of more clinically acute lesions. Non-penetrating chest trauma is responsible for 90% of cases. Echocardiography is the investigation of choice for assessing the mechanism of the tricuspid regurgitation and for diagnosing associated lesions. It should be performed systematically in patients with multiple trauma. The surgical indications are difficult to determine and depend on the patients' symptoms and the type of anatomical lesions. It should be undertaken before right ventricular myocardial dysfunction. Several techniques may be used from valvuloplasty to valve replacement mainly with bioprostheses in symptomatic patients.

[Intrathoracic textiloma after cardiac surgery. Apropos of a case]. / Textilome intrathoracique au décours de la chirurgie cardiaque. A propos d'un cas.

The authors report an exceptionally rare case of intrathoracic textiloma presenting with a recurrence of chest pain after myocardial revascularisation by double internal mammary artery bypass grafting. The diagnosis was suspected before reoperation from the results of echocardiography. CT scanning and magnetic resonance imaging. The authors discuss the clinical and paraclinical features and the treatment. The medico-legal aspects of this surgical complication are not negligeable.

[Cocaine and the heart: a clinical reality]. / Cocaïne et coeur: une réalité clinique.

Cocaine is a drug which has been relatively little used in France until recently but its abuse seems to be on the increase with nearly 1% of 20 year-old-men admitting to having taken it more than 10 times in 1993. The cardiovascular manifestations of cocaine consumption should be known to all cardiological emergency units because of their prevalence and severity. Acute toxicological expertise and retrospective analysis allows formal diagnosis.

[Aneurysm of the interatrial septum with atrial septal defect, disclosed by pulmonary embolism complicated by paradoxical embolism]. / Anévrysme du septum interauriculire avec communication interauriculaire, révélé par une embolie pulmonaire compliquée d'embolie paradoxale.

The authors report the case of a patient admitted to hospital for bilateral phlebitis of the lower limbs, associated with an atrial septal defect. The presence of significant pulmonary hypertension accounted for the paradoxical embolism by inversion of the intracardiac shunt. No recurrence has been observed with a follow-up of six months on anticoagulant treatment.
