Right ventricular (RV) structure and function module

a) SCMR official document standardized acquisition guidelines – relevant extract

1. Right ventricular (RV) short axis views can be obtained in a similar fashion to the LV structure and function module. If the short axis is used for quantification, it is important to place the basal short axis slice immediately on the myocardial side of the right ventricle and to take extra care to exclude appropriate amounts of atrial volume from at least one basal slice at end systole.
2. Transaxial stack of cines covering the RV enable best identification of the tricuspid valve plane.
3. Long axis images should include an RV vertical long axis view aligned with tricuspid inflow and a RV outflow tract view (sagittal plane through the pulmonary valve).
4. Analysis
   a. A similar computer-aided analytic approach is required as for the left ventricle.
   b. Care must be taken with RV trabeculations and with the RV outflow tract after repair of tetralogy of Fallot with a consistent approach used for longitudinal comparison.

b) SCMR official document reporting recommendations – relevant extract

The reporting of right ventricular (RV) and left and right atrial chamber sizes and volumes are optional.  Reporting of left ventricular (LV) volumes is
recommended when multi-slice cine short axes data are acquired from the mitral annulus to the cardiac apex.  When reported, SCMR suggests that right-sided
chambers measurements and the angulation from which the diameters or dimensions are acquired should be reported.  For the left-sided cardiac chambers, the 3-chamber long axis view should be used for identifying LV dimensions.  The SCMR encourages quantitative measures reported on their forms; however, determination of normal, enlarged, small, or not reported may be substituted.

Number 08-05: Acute MI, normal coronaries
History: A 44 yr old lady transferred for primary PCI for chest pain with lateral ST elevation. Troponin I 26, CK 1233. Normal lipids (TC:HDL 3.17). Only risk factor for IHD was hypertension: non-smoker.
