Recurrent Spontaneous Coronary Artery Dissection Leading to Recurrent
Sudden Cardiac Arrests: Who is at risk?
Abstract
Spontaneous coronary artery dissection(SCAD) is a rare cause of acute
coronary syndrome(ACS) with medical management and conservative
therapies usually resulting in favorable outcomes. SCAD often is
recurrent especially in high risk individuals with underlying connective
tissue disorders. Lethal ventricular arrhythmias have been reported in
SCAD without clear indications for secondary prevention with implantable
cardiovert-defibrillator(ICD). Depending on risk factor for recurrence
as well as susceptibility towards ventricular arrhythmias some patients
may benefit from early implantations of ICDs.
