Recurrence of dilated cardiomyopathy after re-introduction of a tricyclic antidepressant.

A causal relationship between treatment with tricyclic antidepressant (TCA) at therapeutic doses and cases of dilated cardiomyopathy has been suspected, but not definitely evidenced. We present a case of a dilated cardiomyopathy, which seemed idiopathic, but occurred during treatment with imipramine and recovered after its withdrawal. For the first recorded time, the cardiomyopathy recurred 9 years later, after a 2-year period of treatment with amitriptyline and lithium, and recovered again 1 year after both psychotropic drugs withdrawal.

Diagnostic accuracy of a 2D left ventricle hypertrophy score for familial hypertrophic cardiomyopathy.

Aims: To study the diagnostic value of a new 2D left ventricle hypertrophy (2D LVH) score in families with hypertrophic cardiomyopathy (HCM) in comparison with the conventional maximal wall thickness (MWT) measurement (>13 mm in adults), which is limited by a low sensitivity in relatives.

Methods And Results: The study was performed in 237 adults from genotyped families with HCM. Population A (derivation sample) comprised 109 adults and population B (validation sample) comprised 128 adults.

Accuracy of European diagnostic criteria for familial hypertrophic cardiomyopathy in a genotyped population.

Background: Since the sensitivity of conventional diagnostic criteria for familial hypertrophic cardiomyopathy (HCM) is low, new diagnostic criteria were proposed by a European collaboration. However, their diagnostic value remains unknown. The aim of the study was to evaluate the accuracy of these new criteria, using the genetic status as the criterion of reference.
