ABSTRACT
Although rare, the discovery of non-compaction cardiomyopathy of the left ventricle (NCVG) is not exceptional. This is a series of three cases discovered incidentally in patients admitted with symptoms of congestive heart failure. The ultrasound criteria established by Stöllberger and cardiac magnetic resonance imaging were used to diagnose noncompaction in our series. Impairment of the left ventricular ejection fraction was very severe in two of our patients. Ionic disturbance was reported in two patients. Antiarrhythmic treatment combined with an external electric shock allowed the ventricular tachycardia to be resuscitated in the first patient. Coronary angiography would have shed light on a possible association with a coronary anomaly. Diuretic and vasopressor therapy combined with organoprotection with a converting enzyme inhibitor were instituted to relieve the heart failure. This series shows us that an improvement in the technical platform is necessary for adequate management of LVNC in our context.
RÉSUMÉ
Bien que rare, la découverte d'une cardiomyopathie de non-compaction du ventricule gauche (NCVG) n'est pas exceptionnelle. Il s'agit d'une série de trois cas découverts fortuitement chez des patients admis pour des symptômes d'insuffisance cardiaque congestive. Les critères échographiques établis par Stöllberger et l'imagerie par résonance magnétique cardiaque ont été utilisés pour diagnostiquer la non-compaction dans notre série. L'altération de la fraction d'éjection du ventricule gauche était très sévère chez deux de nos patients. Des troubles ioniques ont été rapportés chez deux patients. Un traitement antiarythmique associé à un choc électrique externe a permis de réanimer la tachycardie ventriculaire chez le premier patient. Une coronarographie aurait permis de mettre en évidence une éventuelle association avec une anomalie coronarienne. Un traitement diurétique et vasopresseur associé à une organoprotection par un inhibiteur de l'enzyme de conversion ont été instaurés pour soulager l'insuffisance cardiaque. Cette série nous montre qu'une amélioration du plateau technique est nécessaire pour une prise en charge adéquate de la NCVG dans notre contexte.
