title: [Can Doppler echocardiography help to avoid cardiac catheterization in the surgical decision-making in isolated left heart valve diseases?].
abstract: The aim of this study was to assess the value of non-invasive investigation based on clinical evaluation and Doppler echography in deciding the operative indications of patients with isolated left heart valvular lesions compared. Three hundred and thirty five patients were included in a prospective study: 78 had MR, 57 had AR, 150 had AS and 50 had MS. All underwent clinical. Doppler echography and catheter studies. The therapeutic decision was taken blind by two groups of 2 cardiologists. Group I took its decision based on clinical findings and results of Doppler echography whilst Group II took its decision on the clinical and catheter data. For each patient, one of the following three choices was proposed: 1) medical treatment: 2) surgery or valvuloplasty with balloon catheter; 3) request for further information. In addition, in group I, the need for coronary angiography was left to the appreciation of two cardiologists. The quantification of the valvular disease was concordant for groups I and II in 93, 97, 98.5 and 100% for MR, AR, AS and MS respectively. These percentages were respectively 97, 95, 92 and 100% for assessment of left ventricular function. The theoretical management decision was concordant between the two groups for 97% of MR, 94.7% of AR, 95.3% of AS and 94% of MS. Complementary information requiring invasive studies was required by group I in 3.9% of cases. A discordant opinion was obtained in 0.6% of cases (2 cases of AS). Coronary angiography was requested by the cardiologists of Group I in 34% of patients, identifying all patients who underwent coronary bypass surgery. These results show that cardiac catheterisation is no longer an essential diagnostic procedure for discussing the indications of valvular surgery in the majority of patients with isolated left heart lesions.
