ABSTRACT: Background:We report the case of a 58-year-old hypertensive patient under treatment who presented with a ventricular tachycardia unveiling an obstructive cardiomyopathy complicated with an apical aneurysm. Aim: Highlight the rarity of the case and the difficulty of management. Case Presentation: This patient was transferred from Regional Hospital of Ziguinchor in southern Senegal for a brutal dizzy spell without loss of consciousness. The electrocardiogram showed a wide monomorphic QRS complex regular tachycardia with a rate of 215 beats/min. An external electrical cardio version at 300 joules was applied which led to the recovery of a sinus rhythm on the electrocardiogram. The Doppler echocardiography showed an asymetricalmedio-ventricular hypertrophy with a maximum left intraventricular gradient at 10 mm Hg at rest. The coronarography via the radial artery was normal. The evolution was labeled with a recurrence of the ventricular tachycardia. The patient was then put on amiodarone 200 mg, beta-blocker (bisoprolol 10 mg) and anti-vitamin K (acenocoumarol 4 mg). Facing rhythmic instability, an implantable automatic defibrillator was fitted. No complication has been reported after one year of evolution. Conclusion: HCM with medio ventricular obstruction and apical aneurysm complicated with ventricular arrhythmias is a rare entity. Its management is difficult and controversial.
