Case Reports[Traumatic tricuspid insufficiency. Apropos of 2 cases].
The authors report two cases of tricuspid regurgitation by a ruptured anterior papillary muscle secondary to non-penetrating thoracic trauma. In the presence of suggestive clinical and electrocardiographic abnormalities (systolic murmur, right heart failure, right bundle branch block), echocardiography confirmed the tricuspid regurgitation, showed its mechanism and excluded any other intracardiac lesions. ⋯ Traumatic tricuspid regurgitation is a rare condition and the diagnosis is often delayed. Echocardiography is the investigation of choice and guides treatment which is essentially valvular repair in symptomatic patients.

Review Comparative Study[Morphological study by transesophageal echocardiography and clinical aspects of ruptured chordae tendineae in the elderly].
Ruptured mitral chordae tendinae is a classical complication of myxomatous mitral valves or Barlow's syndrome. This complication is controversial in non-myxomatous mitral valve. Of 91 consecutive patients with mitral valve prolapse examined over an 18 months period by transthoracic and transesophageal echocardiography, 42 (18 women and 24 men) with an average age of 76 +/- 8 years (60-93 years) had ruptured mitral chordae tendinae. ⋯ No significant difference was observed between the two groups with respect to age, gender presence of hypertension, dimensions of the cardiac chambers, fractional shortening or localisation of the prolapse related to the ruptured chordae. Fifty-eight per cent of patients in group I were in NYHA functional classes 3-4 as compared to 16% in group II (p < 0.02). The size of the left atrium was significantly greater in group I, 51 +/- 8 mm vs 38 +/- 7 mm (p < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Comparative Study Clinical Trial[Fibrinolytic inhibitors and prevention of bleeding in cardiac valve surgery. Comparison of tranexamic acid and high dose aprotinin].
In order to assess the effects of tranexamic acid in comparison to the high dose regimen of aprotinin recommended by Royston and considered to be the reference in postoperative bleeding in cardiac surgery, 35 consecutive patients were randomised to two groups according to the product prescribed. The global postoperative bleeding was comparable in the two groups (p = 0.49). One surgical reoperation for haemostasis was required in the reference group. ⋯ Tranexamic acid was as effective and as safe as high dose aprotinin. These two substances, in addition to their fibrinolytic inhibitory activity, conserved platelet protection by blocking the action of plasmin. These results seem to justify the preventive use of tranexamic acid from the moment of skin incision, especially in reoperation.

[Incidence and prognosis of early primary cardiogenic shock in myocardial infarction].
The aim of this retrospective study was to analyse the results of coronary reperfusion on the incidence and short and medium term prognosis of early primary cardiogenic shock in acute myocardial infarction. Of 339 consecutive patients admitted within 6 hours of the onset of acute myocardial infarction, 25 (7.4%) had cardiogenic shock from the onset. The majority of patients (18) underwent direct angioplasty with a successful result in 16 cases. ⋯ After an average follow-up of 17 months, 3 of the 7 survivors of the hospital period have died and of the 4 remaining patients, 2 are in the NYHA classes III or IV. Recent therapeutic advances have not influenced the incidence of cardiogenic shock but have significantly increased the proportion of very early cardiogenic shock, whereas the late cardiogenic shocks of more progressive onset, have nearly disappeared (4/339, 1.2% in this series). The prognosis of these early shocks, caused by severe myocardial damage, remains catastrophic and hardly improved by emergency coronary reperfusion by angioplasty and intraaortic balloon pumping.(ABSTRACT TRUNCATED AT 250 WORDS)
