Vitamin D as a Substitute of Catheter Ablation in a Paediatric Patient with High Burden Premature Ventricular Contractions: A Case Report SD01-SD03
Viilor 46-50 Rehabilitation Hospital, Cluj-Napoca, Cluj, Romania.
Catheter ablation is established as a treatment option for patients with high number Premature Ventricular Contractions (PVCs). However, complications can occur: cardiac tamponade, coronary artery injury or infectious endocarditis. Reversible causes such as hypocalcaemia, hypomagnesaemia and hypokalemia can be responsible for PVCs. Here, a case of nine years old boy, with vitamin D deficiency that presented high number PVCs which corrected using vitamin D dietary supplementation was described. A nine-year-old boy was hospitalised in the Cardiology Department for catheter ablation of PVCs. He presented short of breath during football matches and asthenia. Electrocardiography(ECG) and Holter ECG demonstrated high number PVCs with a morphology consistent of Right Ventricular Outflow Tract (RVOT) origin. Catheter ablation was postponed until Vitamin D came to normal values. Dietary supplementation was performed, together with Holter ECG monitoring. After vitamin D normalisation, PVC burden reduced significantly without the need of catheter ablation or anti-arrhythmic drugs. Catheter ablation and anti-arrhythmic drugs can be avoided in patients with frequent PVCs and vitamin D deficiency.
