[Tamponade without cardiac rupture after repetitive thrombolysis in acute myocardial infarction].

The authors report the case of tamponade without cardiac rupture 48 hours after a second course of intravenous thrombolytic therapy undertaken for unstable angina in laterobasal infarction in a 72 year old woman. The outcome after ultrasonic guided pericardiocentesis and surgical drainage (700 cc) was favourable. This is a rare complication of thrombolytic therapy (10 cases) and usually observed after anterior myocardial infarction.

[Can patients with severe left ventricular dysfunction be treated by coronary artery bypass surgery?].

Forty three men and 3 women, with an average age of 59 years (13 to 78 years) underwent aorto-coronary bypass surgery despite severe left ventricular dysfunction (ejection fraction < 35%); 96% of the patients had previous infarction; 60% (N = 28) had unstable angina, 52% (N = 24) had had pulmonary oedema or an episode of congestive cardiac failure. The average ejection fraction was 29 +/- 4%, range 17 to 35%. Thirteen patients had ventricular aneurysms, 4 had grade 3 or 4 mitral regurgitation. The coronary lesions were usually multivessel left main coronary (6), triple vessel disease (27), double vessel disease (12), single vessel disease (1). The average number of bypass grafts per patient was 2.3. The average aorting clamping time was 63 minutes (range 26 to 133 minutes). There were 4 mitral valve replacements, 4 resections of ventricular aneurysms and 1 double procedure (aneurysmectomy and valve replacement). The operative mortality was 2.1% (1 death). During an average follow-up period of 27 months (range 3 to 90 months), there were: 2 recurrent infarctions, 13 episodes of cardiac failure and 8 cardiac deaths (cardiac failure: 5, sudden death: 2, recurrent infarction: 1). Two patients underwent cardiac transplantation. The regression of angina (90% of operated patients were asymptomatic) and the low operative risk, justify aortocoronary bypass surgery despite left ventricular dysfunction in patients with severe symptoms (unstable angina, chronic, invalidating angina). The medium-term results indicate a high risk of cardiac failure which is partially responsible for the secondary mortality rate of 17% at 2 years.

[Do calcium inhibitors have any role in secondary prevention of myocardial infarction?].

The value of using calcium blockers in post-infarction secondary prevention is controversial. The HELD meta-analysis (1989) involving 17,759 patients concluded that they made no contribution in this indication (9.8% mortality rate vs 9.3% in the control group). The findings of the DAVIT II study with verapamil demonstrate a significant reduction in the infarction recurrence rate (18% vs 21.6%) in the treatment group. In the patients without heart failure, there was some benefit in terms of reduced mortality (7.7% vs 11.8%). The true contribution of calcium channel inhibitors, relative to that of beta-blockers in post-infarction medication should be analyzed in function of the various infarction sub-groups (no Q-wave, thrombolytic, with or without left ventricular dysfunction), of the calcium channel inhibitor being investigated and of the administration regimen.

[A rare cause of right cardiac insufficiency after pneumonectomy].

The authors report the case of a 55-year old patient, hospitalized for assessment of progressive right heart failure after left pneumonectomy due to bronchial epidermoid cancer. Right catheterization showed a dip-shaped right ventricular plateau and equal diastolic pressures (DOP 21 mmHg, diastolic pressure of the right ventricle 25 mmHg, capillary pressure 25 mmHg). A chest scan ruled out the possibility of pericardial invasion. Pericardial decortication was carried out on October 3, 1989. Six months later, the clinical signs of right heart failure had regressed. Chronic constrictive pericarditis (CCP) has been reported after cardiac surgery, but not cases have been reported after pulmonary surgery. In the absence of radiotherapy or metastatic invasion, this case leads to a discussion of the possibility of either pericardial trauma during surgery or, more probably, a fortuitous association with tubercular CCP.

[Clinical and angiographic results of delayed revascularization by angioplasty or bypass after intravenous thrombolysis in myocardial infarction].

Between 1988 and 1990, 150 patients treated for an infarction by intravenous thrombolysis underwent coronary arteriography. Sixty seven were managed by revascularisation by angioplasty (n = 49) or bypass (n = 18) more than 48 hours after thrombolysis. In this delayed revascularisation group, the time before initial fibrinolysis was 114 +/- 55 minutes. The artery responsible for the infarction was patent in 88 per cent of cases at 12 +/- 9 days, with ejection fraction being 56 +/- 12 per cent. Indications for revascularisation were: recurrence of angina, Thallium stress test showing redistribution (n = 9), diffuse lesions (n = 11) or tight (greater than 75 per cent) proximal stenosis without vessel wall sequelae (n = 10). Comparison of the bypass and angioplasty groups showed a lower ejection fraction in the former than the latter (47% VS 58%, p less than 0.01), more frequent three-vessel disease (50% VS 6%, p less than 0.01) and more frequent revascularisation of the anterior interventricular (100% VS 37%, p less than 0.01). There were 2 deaths and 5 recurrences of infarction at one year. Follow-up arteriography was performed between at 2 and 6 months in 72% of the patients: 16 had restenosis after angioplasty and 4 occlusion of the graft after bypass. A second revascularisation procedure was necessary 15 times (14 angioplasties, 1 bypass). The outcome after bypass or angioplasty was favourable in 90% of cases in this group of patients exposed to a recurrence of infarction.

[Should inferior myocardial infarction be thrombolysed?].

Recent randomised studies have demonstrated the benefits of administration of intravenous thrombolytic agents in the acute phase of myocardial infarction. Though the benefits are generally acknowledged in cases of anterior wall necrosis, the results in inferior infarction have been discordant. The early patency rate at 90 minutes after thrombolysis is lower in the right coronary and left circumflex than in the left anterior descending artery. The secondary reocclusion rate is twice as high on the right coronary artery. The significant increase in ejection fraction after thrombolysis has only been demonstrated in 2 of the 8 studies in the literature. The benefits in terms of early mortality were not significant in the GISSI study. A significant decrease in early mortality (7.2% vs 8.8%) was observed only in the ISIS 2 study with streptokinase. The reinfarction rate at 1 year was twice as high when the initial infarct was on the inferior wall. Analysis of the results in the literature shows that the benefits of intravenous thrombolysis was clearcut in certain subgroups of inferior infarction: ST elevation in over 3 leads, mirror-image anterior lead changes, very early treatment (before the 3rd hour), complicated infarcts (atrioventricular block, right ventricular extension, hypotension) or in inferior infarcts occurring after previous anterior infarction.

[Postinfarction segmental asynergy: correction after angioplasty. Predictive value of exercise thallium scintigraphy].

The aim of this study was twofold: to evaluate the frequency of reversibility of segmental post-subendocardial infarction asynergy after coronary angioplasty, and to test the predictive value of the redistribution phenomenon during stress Thallium scintigraphy with respect to the reversibility of segmental asynergy. The inclusion criteria for this study were: previous postsubendocardial myocardial ischaemia with residual resting or effort ischaemia documented with or without the Thallium test, segmented asynergy documented by quantitative analysis of the ventriculography, complete correction of coronary angioplasty of stenotic single or double vessel disease, a balanced coronary distribution or dominant left coronary in cases of lesion of the circumflex artery. Out of 254 consecutive angioplasty procedures 39 patients met these inclusion criteria. The location of the subendocardial infarct (SEI) was anterior in 17 cases and inferior in 22 cases. The study protocol included a Thallium scintigraphy from the 10th day after SEI, ventriculography 24 hours later, angioplasty and control ventriculography 24 hours after angioplasty. Comparison of the two ventriculographies opposed Group A (reversible asynergy) and Group B (irreversible asynergy) according to criteria defined in 15 normal subjects whose average regional ejection fraction (REF) was 0.53 +/- 0.11. This result enables definition of normal segmental motion if the REF greater than 0.30 (mean--2 SD); hypokinetic if the REF greater than 0.30 or akinetic if the REF less than 0.10 (mean--4 SD). An increase of REF of 0.15 (50% of the minimal normal value) allowed definition of reversibility of asynergy. By these criteria, 19 patients (48.7%) had reversible asynergy after PTCA; 20 had definitive asynergy (51.3%).(ABSTRACT TRUNCATED AT 250 WORDS)

[Dysfunction of aortocoronary bypass. Prognosis].

From 1978 to 1988, 108 patients with at least one occluded or stenosed aorto-coronary bypass graft (over 75% stenosis) underwent coronary angiography on average 31 months after the initial coronary bypass surgery. The occluded or stenosed coronary graft was either a saphenous vein (n = 126 including 9 sequentials) or internal mammary artery (n = 5). The bypassed artery was the left anterior descending (n = 66), right coronary (n = 40), left marginal (n = 25) or diagonal (n = 9). The number of occluded or stenosed grafts by patient was 1.2. The left ventricular ejection fraction was 55% (range 25 to 77%). During a mean follow-up period of 60 months after coronary angiography, there were 14 cardiac deaths and 15 non-lethal myocardial infarctions. Treatment comprised 12 angioplasties, 26 new bypass grafts and 3 cardiac transplantations. The 8 year actuarial survival was 84%. The survival without infarction at 8 years was 69%. Survival was significantly decreased to 72% when the occluded or stenosed graft was located on the left anterior descending artery. The survival without infarction at 8 years was 52% in the patients with dysfunction of left anterior descending artery grafts and 89% when the diseased graft was located on another artery (right coronary, left marginal, diagonal). Therefore, the data of this retrospective study show that coronary graft dysfunction on the right coronary, left marginal or diagonal arteries do not greatly influence life expectancy in the medium term after coronary bypass surgery.(ABSTRACT TRUNCATED AT 250 WORDS)

[Prognosis of ischemic mitral valve insufficiency].

Seventy-nine patients with ischemic mitral regurgitation were followed up for a period of 20 +/- 8 months. The risk of death increased with age and cardiac failure at the time of inclusion. The risk of cardiac events increased with these factors and also with raised serum creatinine and decreased echocardiographic fractional shortening. The global 2 year survival was 72.8% and survival without a further cardiac event was 48.7%. Surgery and angioplasty increased global survival and freedom from cardiac events of patients with severe regurgitation (74.9% and 68.8% versus 59.4% and 46.1% for medical therapy alone). The functional improvement was also greater in patients undergoing surgery or angioplasty (80% of patients in NYHA Stage I versus 53.8% in the medical group). Angioplasty was only performed in cases of paroxysmal mitral regurgitation by reversible papillary muscle ischemia. Surgery (coronary bypass usually associated with mitral valve replacement) was associated with better results than medical therapy alone in permanent mitral regurgitation by papillary muscle dysfunction or rupture. Despite a high immediate mortality, this option should be considered rapidly in cases of severe ischemic mitral regurgitation with pulmonary oedema.

[Initial and mid-term results of coronary angioplasty in early post-infarction unstable angina].

The aim of this study was to assess the immediate efficacy and the medium-term risks and results of percutaneous transluminal coronary angioplasty (PTCA) in early post-infarction unstable angina. Thirty-six patients were included for a series of 248 consecutive PTCA procedures performed between December 1985 and January 1989. The average age was 56 years (range 35 to 84 years). The initial infarct was anterior (N = 16), inferior (N = 15), lateral (N = 5), without a Q wave (N = 22), transmural (N = 14) and treated by thrombolysis in 42 p. 100 of cases. The interval between initial infarction and PTCA was 16 +/- 3 days. A primary success was obtained in 33 cases (92%). One patient died of electromechanical dissociation at the beginning of the procedure. Two infarcts occurred due to acute coronary occlusions. None of the patients required emergency coronary bypass surgery. The specific risk of PTCA in early post-infarction unstable angina is acute coronary occlusion. This complication was observed in 9 patients (25%) and it required immediate repeat PTCA, associated with thrombolytic therapy in four cases. Coronary occlusion was more common in patients with transmural infarcts than in those without Q-waves (43% vs 14%; p less than 0.01) and in patients treated initially by thrombolysis compared with those not treated by thrombolysis (40% vs 15%; p less than 0.05). No fatalities or reinfarctions occurred during follow-up (average 9 +/- 8 months, range 2 to 35 months). A good clinical result was maintained in 71 per cent of patients treated by PTCA alone. Seven repeat PTCA procedures and 3 coronary bypass operations were performed during follow-up.(ABSTRACT TRUNCATED AT 250 WORDS)

[Is the prognosis of non-thrombolysed inferior infarction benign?].

Between 1978 and 1983, 2,970 coronary angiographies were performed at the Cardiology Clinic of Necker Hospital; 220 survivors of an initial Q-wave inferior infarction who had not received thrombolytic therapy were selected. The ejection fraction was 55 +/- 11 per cent, and the indexed end diastolic left ventricular volume was 108 +/- 29 ml/m2. The left anterior descending artery was diseased in 57 per cent of cases. The incidence of multivessel disease was 67 per cent. Two hundred and eleven patients (96%) were followed up for 79 +/- 22 months. The prevalence of cardiovascular events was: cardiac deaths: 22 (10%), recurrent infarction: 20 (9%), angina requiring coronary bypass surgery: 60 (28%), cardiac failure: 22 (10%). The 10 year actuarial survival was significantly lower in patients with an ejection fraction less than 45 per cent (46% vs 91%) and in patients with triple vessel disease (62% vs 92% and 88%). The survival was not lower in patients with stenosis of the left anterior descending artery.

[Restenosis after transluminal coronary angioplasty. Clinical and therapeutic aspects].

To assess the incidence and clinical presentation of restenosis after successful coronary angioplasty, and the short- and mid-term results of its treatment, 160 patients, who underwent a first coronary angioplasty between May 1987 and December 1988, were closely monitored. Restenosis is defined as a loss of 50% or more of the initial gain in area and/or 30% or more in diameter, or chronic coronary occlusion. These criteria were met in 43 patients (27%) within 5.1 months (1-6 months), on the average, after angioplasty. Restenosis was expressed as unstable angina in 51% of the patients, stable angina in 30%, and abnormal thallium myocardial scintigraphy under exercise in 14%. Myocardial infarction was never the revealing symptom. In 63% of the cases, the pain caused by restenosis repeated the initial angina. A second angioplasty was performed in 75% of the patients with a success rate of 93%, in the absence of an occlusion, and a 37% rate of further restenosis.

[Late occlusive thrombosis of mitral prosthesis with sinus rhythm. Report of two surgically treated patients].

Two cases are reported of late occlusive thrombosis of a mitral bioprosthesis with sinus rhythm. Two men were concerned (40 and 54 years of age), hospitalized for acute pulmonary oedema which was resistant to medical treatment, 3 years after replacement of a mitral valve (Carpentier Edwards No. 31 and Liotta No. 25). Catheterization showed that in both cases there was an average transmitral holodiastolic gradient greater than 25 mmHg. Emergency surgery revealed two anatomical forms of occlusive thrombosis: in one case, a localized red thrombus hindered the opening of a valve cusp; in the other, exuberant fibrin deposits lined the ventricular face of the valve cusps. There were no signs of degeneration of the bioprostheses and, in particular, there was no calcification. Both patients were asymptomatic 1.5 years and 3 years respectively after their operations. Late occlusive thromboses of mitral bioprostheses are exceptional (13 detailed cases collected from the literature).

[The hospital course of thrombolyzed myocardial infarction: role of bypass and angioplasty].

The frequency of indications for revascularization (bypass and angioplasty) after intravenous thrombolysis in myocardial infarction (MI) varies from 3.3% (Gissi) to 60% (Tami). Initial progress in 30 patients hospitalized consecutively for MI treated by thrombolysis (group A) was compared with that of 30 MI patients treated conventionally (group B) over the same period. There were no between group differences in age, sex, infarction history, bypass history, topography of infarction or extent of coronary lesions. Group A was characterized by a larger ejection fraction (51.7 +/- 9.2% vs 44.9 +/- 10%; p less than 0.05), a higher frequency of ischemic recidivism (33% vs 10%; p less than 0.05), and more frequent indications for secondary revascularization (50% vs 20%; p less than 0.02).

[Coronary bypass after thrombolysis].

Owing to the development of transluminal angioplasty, coronary bypass surgery has now well-defined indications in patients who underwent thrombolysis. It may need to be performed in an emergency, but fortunately this only occurs in a few cases: in case of occlusion of the left main coronary vessel or equivalent lesions, when thrombolysis has failed and in case of failure of angioplasty with obliteration of large vessel and a still viable myocardium, and when the patient continues to suffer or shows signs of heart failure. The operative risk and the risk of haemorrhage then reach 10 p. 100. The installation, prior to surgery, of an intra-aortic counterpulsation system is useful in case of shock or left ventricular failure. Delayed coronary bypass is indicated mainly in case of three-vessel lesions with a less than 40 p. 100 ejection fraction, in case of stenosis of the left main coronary vessel or equivalent lesions, and in patients whose lesions are not amenable to angioplasty on a good caliber vessel, with a still viable myocardium. The operative risk in such cases is distinctly lower (2.4 p. 100). The long-term results obtained confirm the value of coronary bypass surgery when it becomes necessary after thrombolysis.
