We describe successful LMCA and branch recanalization via intra coronary infusion of recombinant tissue plasminogen activator and discuss management of acute coronary thrombosis in children with single ventricle physiology.
Homozygous LH2 knockout (LH2<sup>-/-</sup>) embryos failed to develop normally and died at early embryonic stage E10.5 with abnormal common ventricle in a heart, i.e., an insufficient wall, a thin ventricular wall, and loosely packed cells.
The minor allele C in <i>GATA4</i>: rs17153694 T > C increased the risk of tetralogy of Fallot, whereas minor alleles in <i>TBX1</i>: rs41298006 G>A, <i>FGF10</i>: rs75629618 C>T, <i>FGF10:</i> rs10461755 G>A, <i>FGF10:</i> rs75632187 A>G, and <i>FGF10:</i> rs12518964 G > A were associated with increased risk of single ventricle.
Conclusions PDE5 is increased in failing SV heart disease myocardium, and pathological gene expression changes in SV heart disease serum-treated neonatal rat ventricular myocytes are abrogated by PDE5i.
Homozygous deletion of Rfx4 resulted in formation of a single ventricle in the forebrain, and severe dorsoventral patterning defects in the telencephalon and midbrain at embryonic day 12.5, a collection of phenotypes that resembled human holoprosencephaly.
By univariate analysis, younger age (5 vs. 284 days, P < .001), lower weight (3.2 vs. 7.5 kg, P < .001), single ventricle physiology (P = .05), longer cardiopulmonary bypass time (176 vs. 94 min, P < .001), need for delayed sternal closure (P < .001), and higher STAT category (P < .001) were associated with EAT.
Then, for each patient the following simulations were performed: (a) CF VAD to assist the left ventricle (single ventricle) + a PF VAD to assist the right ventricle (cavo-pulmonary connection) (LCF + RPF); (b) PF VAD to assist the left ventricle (single ventricle) + a CF VAD to assist the right ventricle (cavo-pulmonary connection) (RCF + LPF).
The association of APOE genotype with ND outcomes was assessed in a combined cohort of patients with single-ventricle CHD enrolled in the Single Ventricle Reconstruction and Infant Single Ventricle trials.
Renin-angiotensin-aldosterone system genotype may identify a high-risk subgroup of single ventricle patients who fail to fully benefit from volume-unloading surgery.
The endothelin-1G5665T genotype was significantly associated with transplant-free survival for the group as a whole (P = .002), with the greatest effect in children with hypoplastic left heart syndrome (n = 64, P = .0002) as opposed to patients with other types of single-ventricle anatomy (n = 101, P = .1).
