Catecholaminergic polymorphic ventricular tachycardia screening
Introduction
Overview
Overview
There is insufficient evidence to recommend routine screening for Catecholaminergic polymorphic ventricular tachycardia. But screening among relatives is indicated when a likely pathogenetic mutation is identified in clinically affected index cases. Screening methods for CPVT are exercise stress testing and genetic testing.
Screening
Screening
- Screening of all the first-degree relatives is indicated when a likely pathogenetic mutation is identified in clinically affected index cases.
- Clinical and genetic evaluation, including exercise stress testing is recommended for both first- and second-degree relatives.
- Exercise stress testing has a specificity of 97% and a sensitivity of 50% for predicting the presence of the familial CPVT-associated mutation in asymptomatic relatives of CPVT patients.[1][2][3]
- Genetic testing for RyR2 and CASQ2 mutations should also be considered in first-degree relatives, even with a negative clinical phenotype.
- Screening by repeat exercise testing is also recommended in first-degree relatives of mutation-negative patients with CPVT, depending on the age of the relative.[4]
