LVNC (left ventricular non-compaction) is a rare congenital cardiomyopathy with a reported incidence of 0.05% in adults. It can occur in isolation or affect both ventricles. It’s characterized by prominent LV trabeculae and deep intertrabecular recesses which are filled with blood from the ventricular cavity without evidence of communication to the epicardial coronary artery system. Frequent premature supra ventricular tachycardia as unique finding in LVNC cardiomyopathy is rare manifestation of this disease. We report a case of a frequent persistent supraventricular tachycardia as first manifestation of a patient with LVNC cardiomyopathy in a young healthy woman who despite radio frequency ablation therapy of the supraventricular tachycardia remains symptomatic. The patient was later placed on medical therapy based on a non-cardio selective beta-blocker with a good clinical outcome without recurrent of supra-ventricular arrythmias.
Drugs used to treat cardiovascular disease as well as those used in the treatment of multiple other conditions can occasionally produce exaggerated prolongation of the QT interval on the surface electrocardiogram and the morphologically distinctive polymorphic ventricular tachycardia that results is known as «torsade de pointe». «Torsade de pointe» (TDP) is a characteristic polymorphic ventricular arrhythmia associated with delayed ventricular repolarization as evidenced on the surface electrocardiogram by QT interval prolongation. It typically occurs in self-limiting bursts, causing dizziness and syncope, but may occasionally progress to ventricular fibrillation and sudden death. This rare case report showed the potential higher risk of the occurrences of «Tdp» when levetiracetam (KEPPRA) was used in combination therapy with fluconazole, which is already a known medication with the risk of causing polymorphic ventricular arrhythmia.
Acute aortic dissection on bicuspid aortic valve (BAV) type 0 is a rare especially in young masculine. Risk factors like smoking and intensive sport activities can hasten their apparition especially in non-diagnosed population. Trans thoracic echocardiography is very important in the diagnosis of BAV whereas Angio CT scan helps to confirm acute aortic dissection. Treatment is based on surgery for type A Stanford classification for acute aortic dissection. We report a rare case of acute aortic dissection masquerading a rare type of BAV, type 0 in a young sportive male with no history of heart disease who presented for the first-time with acute chest pain after lifting a heavy weight metal at the complex sport center. Patient was initially placed on medical treatment before surgery for heart valve and root replacement (Bentall procedure).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
