The left heart after pulmonary valve replacement in adults late after tetralogy of Fallot repair

Relation of Biventricular Strain and Dyssynchrony in Repaired Tetralogy of Fallot Measured by Cardiac Magnetic Resonance to Death and Sustained Ventricular Tachycardia

“…Traditional CMR factors such as ventricular dysfunction, RV dilation, and RV mass-to-volume ratio have all been well documented as specific risk factors for poor outcomes. 7e9, 18,19 These findings were observed, as well, in our cohort. Reports of outcomes related to novel imaging techniques such as deformation analysis have begun to appear in the literature.…”

Pulmonary Valve Replacement After Operative Repair of Tetralogy of Fallot

“…Effect of PVR on RV. Since the first report by Vliegen et al (9) about the improvement of RV parameters assessed by cardiac MRI, several studies also observed these findings with the volumetric measures before and after PVR to better understand the response of the RV after removal of volume overload (10)(11)(12)(13)(14)18,19,22,24,(27)(28)(29)33,34,36,38,39,(41)(42)(43)46).…”

“…After evaluating 22 studies (9)(10)(11)(12)(13)(14)18,19,22,24,(27)(28)(29)33,34,36,38,39,(41)(42)(43)46) that reported data about pre-operative and pos-toperative indexed RVEDV and 18 studies (9-14, 18,22,24,28,34,36,38,39,41-43,46) that reported indexed RVESV, we used the meta-regression and concluded that populations with greater pre-operative indexed RVEDV measures presented the best responses in terms of RV geometry change in the post-operative period. Likewise, populations with greater pre-operative indexed RVESV measures presented the best responses in terms of RV geometry change in the post-operative period.…”

Determinants of left- and right‑ventricular ejection fractions in patients with repaired tetralogy of Fallot: a cardiac magnetic resonance imaging study

“…In the case of the model predicting RVEF, we entered the following LV parameters: LVEF and LVEDV Previous studies in patients treated with pulmonary valve replacement (PVR) provided an insight into abnormal RV and LV function prior to PVR and the ventricular responses after treatment either with surgery or percutaneous pulmonary valve implantation. 6,[18][19][20] Particularly, those studies demonstrated a beneficial response of LV, in terms of improved LVEDV and LVEF, to changes in RV loading conditions. The mechanisms responsible for improved LV function after PVR and deleterious effects of PR on LVEF are multifactorial.…”
