Table 4. Prevalence of Established CMR Criteria for Arrhythmogenic Right Ventricular Cardiomyopathy.

RV Tachycardia Patients Controls P Value
Major Volumetric Criterion: *

Minor Volumetric Criterion: *
RVEDVI ≥100 to <110 mL/m2 (males), ≥90 to <100 mL/m2 (females)		 11% (5/44) 21% (3/14) 0.38
Any Volumetric Criteria (Minor or Major) 20% (9/44) 29%(4/14) 0.71
RVEF ≤40% † 5% (2/39) 0% (0/16) 1.0
RVEF >40% to ≤45% † 0% (0/39) 0% (0/16) -
RV wall motion abnormalities:
regional akinesis or dyskinesis,		 4% (2/46) 0% (0/16) 1.0
ARVC Major Criteria ‡

  • Regional RV akinesis or dyskinesis

  • and 1 of the following:
    • — RVEDVI ≥110 mL/m2 (male) or ≥100 mL/m2 (female)
    • — or RVEF ≤40%
 4% (2/46) 0% (0/16) 1.0
ARVC Minor Criteria ‡

  • Regional RV akinesis or dyskinesis

  • and 1 of the following:
    • — RVEDVI ≥100 to <110 mL/m2 (male) or ≥90 to <100 mL/m2 (female)
    • — or RVEF >40% to ≤45%
 0% (0/46) 0% (0/16) -

RVEDVI refers to right ventricular end diastolic volume index; RVEF, right ventricular ejection fraction

*

Indexed volumetric indices unavailable for 4 subjects (2 patients, 2 controls) due to absence of height/weight data; data presented for remainder of study population (n=58).

†

RV ejection fraction could not be calculated for 7/46 patients due to arrhythmia-related impaired ECG-gated imaging.

‡

Classification required quantification of RVEF, RVEDVI, or both
