Red Flag

Premature ventricular contractions (PVCs) are common and generally benign in childhood and tend to resolve spontaneously in most cases. When PVCs occur frequently, an arrhythmia-induced cardiomyopathy may be present requiring medical or catheter ablation. PVCs are only rarely the manifestation of a cardiomyopathy. The purpose of this review is to provide some tips and tricks to raise the suspicion of a cardiac disease based on the presence and characteristics of PVCs in children.

Monomorphic ventricular tachycardia (VT) may occur in the presence or absence of structural heart disease. The standard therapy for patients with structural heart disease at high risk of sudden cardiac death due to VT is the implantable cardioverter defibrillator (ICD). While ICDs effectively terminate VT and prevent sudden cardiac death, they do not prevent recurrent episodes of VT, since the underlying arrhythmogenic substrate remains unchanged. However, shocks from an ICD increase mortality and impair quality of life. These limitations as well as continuous advancements in technology have made catheter ablation an important treatment strategy for patients with structural heart disease presenting with VT. Idiopathic ventricular arrhythmias include premature ventricular contractions and VT occurring in the absence of overt structural heart disease. In this setting, catheter ablation has evolved as the primary therapeutic option for symptomatic ventricular premature beats and sustained VTs and is curative in most cases. This chapter presents an overview of the principles of invasive diagnosis and treatment of monomorphic VTs in patients with and without structural heart disease and delineates the clinical outcome of catheter ablation. Finally, the chapter provides an outlook to the future, discussing potential directions and upcoming developments in the field of catheter ablation of monomorphic VT.

The case concerns a difficult but successful right ventricular outflow tract ectopy catheter ablation in a fit and well 33-year-old man with a 16-year history of symptomatic premature ventricular contractions (PVCs). Beta blockade medication had become ineffective in suppressing the PVCs, and a 24-hour Holter monitor revealed a high burden of ectopy (10%). An echocardiogram and cardiac MRI showed a structurally normal heart. During the procedure, it became impossible to uncurve the catheter, and it lodged in the patient’s right femoral artery. Immediate collaboration with interventional cardiology and interventional radiology was required to resolve the issue. The case demonstrates that excellent teamwork and calling rapidly on input from subspecialties are integral to overcoming unexpected events and to achieve a safe and successful outcome. The patient involved was a medical student at the time and as one of the coauthors offers a unique insight.
