A congenital cardiac malformation in which there are deep, endothelial lined, blind-ended intramyocardial tunnels communicating with the right ventricular chamber. Additional information: these occur in the setting of pulmonary atresia or severe right ventricular outflow tract obstruction, intact ventricular septum and a patent tricuspid valve. These right ventricular sinusoids do not communicate with the coronary arteries. Where connections from the right ventricle to the coronary arteries exist, one should code for "Congenital coronary artery-to-right ventricular fistula".

Additional information: these occur in the setting of pulmonary atresia or severe right ventricular outflow tract obstruction, intact ventricular septum and a patent tricuspid valve. These right ventricular sinusoids do not communicate with the coronary arteries. Where connections from the right ventricle to the coronary arteries exist, one should code for "Congenital coronary artery-to-right ventricular fistula".

    Right ventricular myocardial sinusoids
    A congenital cardiac malformation in which there are deep, endothelial lined, blind-ended intramyocardial tunnels communicating with the right ventricular chamber. Additional information: these occur in the setting of pulmonary atresia or severe right ventricular outflow tract obstruction, intact ventricular septum and a patent tricuspid valve. These right ventricular sinusoids do not communicate with the coronary arteries. Where connections from the right ventricle to the coronary arteries exist, one should code for "Congenital coronary artery-to-right ventricular fistula".
