title: [Role of peri-operative treatment in the surgery of advanced valvular cardiopathies].
abstract: Between January 1981 and October 1982, 100 consecutive patients with valvular heart disease (49 p. 100 polyvalvular disease) underwent surgery. All had severe lesions; Class III or IV of the NYHA classification; cardiomegaly with an average cardio-thoracic ratio of 59 +/- 7.7 p. 100; a cardiac index of less than 2.5 1/min/m2 in 70 p. 100 of cases; pulmonary hypertension (mean PAP : 31.93 +/- 12.17 mmHg) in 89 p. 100 of cases. Half the patients were in atrial fibrillation and all had been on chronic digitalo-diuretic therapy before surgery. Thirty of the 41 patients given preoperative venous vasodilator therapy had significant reductions of their cardiothoracic ratios (63 +/- 1.5 p. 100 vs 59.1 +/- 1.6 p. 100, p less than 0.001). Conservative surgical procedures were possible in 58 cases of mitral valvuloplasty and 5 aortic valvuloplasties. Correction of functional tricuspid regurgitation (34 p. 100) was systematic. Tricuspid regurgitation masked by salt and water depletion was detected by digital palpation after clamping the pulmonary artery. In 8 cases the aortic ring had to be enlarged. The low hospital mortality (6 p. 100) and the lack of postoperative complications (assisted ventilation for less than 24 hours in 92 p. 100 of cases) compare favourably with other reported series.
