Aims: Restrictive valvular disease (RVD) has recently been reported in patients after benfluorex exposure. However, little is known about its prevalence and echocardiographic features. The aim of our study was to assess the frequency of benfluorex exposure in patients with RVD and to describe their echocardiographic characteristics.

Methods And Results: In a single centre study, patients with a final diagnosis of unexplained RVD were studied. Patients were interrogated for their previous use of benfluorex or other appetite-suppressant drugs (ASDs). Forty seven consecutive patients, aged 59 ± 9.6 years, with RVD were found [42 (91%) women]. Among them, 35 (74%) had previous treatment with ASD, including benfluorex in 34 patients. Among the latter, 14 (40%) have been exposed to benfluorex alone, 20 (60%) in combination with another ASD. Echocardiographic features included isolated mitral or aortic restricted valve motion in 19 patients (40%), and combined mitral and aortic involvement in 28 (60%).Twenty-seven (96%) of the latter had been exposed to benfluorex. As compared with the 'no ASD' group (n= 12), patients in the benfluorex group (n= 34) were more frequently female, had more frequent arterial hypertension and hypertriglyceridemia, and presented more frequently with combined mitral and aortic disease (79 vs. 8%, P < 0.001). Valve stenosis and tricuspid involvement were rare in the benfluorex group.

Conclusion: The frequency of benfluorex exposure is high in patients with unexplained RVD. Combined aortic and mitral restrictive valve regurgitation is highly suggestive of valvular disease associated with benfluorex or other ASD therapy and may alert clinician about the possibility of this diagnosis.

Global longitudinal strain as a major predictor of cardiac events in patients with depressed left ventricular function: a multicenter study.

J Am Soc Echocardiogr 2010 Oct 1;23(10):1019-24. Epub 2010 Sep 1.

Cardiologic Hospital and INSERM 828, Bordeaux University Hospital Center, Pessac, France.

Background: The risk stratification of patients with left ventricular (LV) dysfunction can be performed using echocardiographic parameters such as the ejection fraction (EF). Recently, new technologies based on deformation measurements have been shown to identify early myocardial dysfunction before EF decrease. Consequently, tools such as two-dimensional strain have been incorporated into echocardiographic systems, allowing for fast, reliable, and reproducible calculation of longitudinal components of LV systolic deformation. The hypothesis in this study was that as a more sensitive marker of LV dysfunction, longitudinal strain would allow for the risk stratification of patients with heart failure.

Methods: This multicenter study included 147 patients with heart failure with LV EFs ≤ 45% (mean age, 64 ± 14 years; 74% men; mean LV EF, 29.9 ± 8.9%). Conventional echocardiographic parameters as well as global and segmental longitudinal strain were measured and compared with these values in a control population. Patients were monitored for cardiac events, defined as a composite criterion, over 12 months.

Results: Clinical events were observed in 20% of patients during the 12-month follow-up period. On receiver operating characteristic curve analysis, global longitudinal strain had the highest prognostic value (area under the curve, 0.83) and the highest combination of sensitivity (73%) and specificity (83%), using a cutoff value of -7%.

Conclusion: Strain assessment is highly feasible and reliable in patients with LV dysfunction and allows for cardiovascular risk stratification in patients with heart failure with greater accuracy than LV EF.

Ventricular arrhythmias during Tako-tsubo syndrome.

Int J Cardiol 2008 Aug 15;128(2):e50-3. Epub 2007 Aug 15.

Tako-tsubo syndrome is a recently described form of cardiomyopathy. Its pathophysiology remains unknown. However, the main demographic, clinical, electrocardiographic and biologic characteristics of the disease have been described by previous reports. Retrospective studies are essential to help describe this rare disease, although they might have several skews. Previous reports have observed a mortality rate between 0 and 8%. In our serie, demographic, clinical, electrocardiographic and biologic results are similar with those previously reported. However, the mortality rate observed was higher than expected. Refractory ventricular arrhythmias leading to death have been encountered in 15% of patients. Tako-tsubo syndrome may present as sudden death and its mortality rate may have been underestimated in previous reports.
