Anticoagulation is the treatment of choice for all SVT and proper treatment of the MPD is recommended in patients with SVT associated with the JAK2(V617F) mutation.
Anticoagulation therapy combined with low-dose aspirin and proper treatment of the MPD is recommended in patients with SVT associated with the JAK2(V617F) mutation.
Both miR‑1 and miR‑133 levels showed significant differences between the SVT and VT groups (P=0.004 and P=0.046, respectively), and a significant decrease in miR‑1 levels was observed in the SVT group as compared with the controls (P<0.001).

Criteria to identify patients at high risk of CALR mutations in this test cohort was used and evaluated in a validation cohort that included 209 patients with SVT.
Immunohistochemistry and western blot further showed disturbed distribution and significantly reduced expression of Connexin 43 (Cx43) in the SVT group (SVT vs. Normal P=0.010, SVT vs. non-SVT P=0.012).
In addition, our findings in JAK2(V617F)-negative SVT patients indicate an important role for the 46/1 haplotype in the etiology and diagnosis of SVT-related MPNs, independent of JAK2(V617F), that requires further exploration.
Patients without PTPN11 mutations (34%) showed a higher frequency of family history of sudden death (P = 0.007), increased left atrial dimensions (P = 0.05), bradyarrhythmias (P = 0.04), episodes of supraventricular tachycardias (P = 0.06), atrial fibrillation (P = 0.009), and nonsustained ventricular tachycardias (P = 0.05) during Holter monitoring.
Rare genetic variants in TNNI3K encoding troponin-I interacting kinase have been linked to a distinct syndrome consisting primarily of supraventricular tachycardias and variably expressed conduction disturbance and dilated cardiomyopathy in 2 families.
Recent research has demonstrated in patients with MPN the existence of factors increasing the risk of SVT such as the presence of the JAK2V617F mutation and its 46/1 haplotype.
Serious adverse events occurred in 7 patients (6.5%) in the interferon beta-1a group and included infection (in 2 patients) and supraventricular tachycardia (in 1 patient).
Seventeen consecutive patients who presented to our vascular laboratory with isolated SVT had a coagulation profile performed that included antithrombin III (AT III), protein C (PC), protein S (PS) antigen and activity levels, activated protein C (APC) resistance, factor V DNA mutation, and coagulation factors II and X.
