Overreaction to noncompaction in a patient with ankylosing spondylitis, Parkinson disease, migraine and myopathy

A patient with ankylosing spondylitis, migraine, Parkinson syndrome, renal insufficiency and myopathy, received an implantable-cardioverter-defibrillator because of asymptomatic left ventricular hypertrabeculation/noncompaction as primary prophylaxis against sudden cardiac death. Inadvertently the ventricular lead was placed in a cardiac vein, the patient suffered from pericardial effusion and it was impossible to remove the lead. Implantation of an implantable-cardioverter-defibrillator simply upon the presence of LVHT appears not justified and may be more harmful than beneficial. Studies about the risk of SCD in adults with LVHT are necessary and will hopefully clarify if primary prevention of SCD is indicated.
