Catecholaminergic polymorphic ventricular tachycardia

Question Question

I have been diagnosed with CPVT. I've been off medication for a few years and have been playing sports regularly. I've never had any syncope. I just read that if untreated CPVT is highly lethal. And now I'm starting to care. I have some questions about this disease: Is there any case of remission? Is it curable? Are sports under treatment better than without treatment? Is there a CPVT specialist anywhere in the world? What is the most up-to-date article/research about this disease?

Can catecholaminergic polymorphic ventricular tachycardia go into remission?

In medicine the word "remission" is often used to refer to a condition where there is no evidence of ongoing disease activity. The signs and symptoms of catecholaminergic polymorphic ventricular tachycardia (CPVT) are typically not constant, but serious concern is warranted for sudden CPVT events that may be triggered by activity or emotional stress. It has been estimated that 83% of people with CPVT will experience CPVT related symptoms. Symptoms of CPVT often present in childhood (75% by age 20),^[1]^[2] however CPVT has presented in older adults as well.^[2]

Do all people with catecholaminergic polymorphic ventricular tachycardia require treatment?

It has been recommended that all people clinically diagnosed with catecholaminergic polymorphic ventricular tachycardia (CPVT) receive treatment. Some individuals who have never had or demonstrated symptoms of CPVT, for example asymptomatic family members with CASQ2 gene mutations, may still benefit from treatment.^[3] We recommend that you speak with your healthcare provider regarding your treatment options.

Can people with catecholaminergic polymorphic ventricular tachycardia play sports?

It has been generally recommended that young people with genetic heart disease be "cautioned against virtually all forms of vigorous physical activity."^[1] We recommend that you speak with your healthcare provider for further advice regarding your activities and restrictions.

How might catecholaminergic polymorphic ventricular tachycardia be treated?

Treatment of adults with catecholaminergic polymorphic ventricular tachycardia (CPVT) related arrhythmias typically involves the use of beta blockers. An implantable cardioverter-defibrillator (ICD) and beta blocker treatment may be considered for people with CPVT who have experienced a heart attack, fainting spells, or sustained abnormal heart rhythms on beta blockers alone. If these individuals still experience heart rhythm abnormalities flecainide and/or verapamil may also be recommended. People whose condition remains resistant to therapy may be counseled regarding further treatment options, such as left sympathetic denervation.^[3]
