Commentary: Right ventricle, right time

Circulation time determinations from the right ventricle.

The determination of the circulation time from the ventricle to the face using fluorescein and ultraviolet light eliminates all of the variable factors from the venous side of the circulation and gives evidence specifically of the presence or absence of an intraventricular right to left shunt. The most important clinical application is the differentiation of tetralogy of Fallot from pulmonary v...

Right coronary artery fistula to right ventricle.

1 of 2 DESCRIPTION A murmur was noted in a 2-year-old patient who was otherwise asymptomatic. The patient was born by caesarean section at 37 weeks gestation. No signifi cant family history was present. Clinical examination revealed a continuous murmur at the sternal edge. Echocardiography did not reveal any abnormality. Cardiac catheterisation revealed a communication between the right coronar...

Double outlet right ventricle.

Double-chambered right ventricle.

Thirty (10.8%) of 279 patients undergoing correction of a ventricular septal defect (VSD) from January, 1972, to September, 1986, also had a double-chambered right ventricle (DCRV). Age at operation ranged from 1.3 to 18.8 years (mean, 6.7 +/- 4.5 years [+/- standard deviation]). Seventeen patients were male, and 13 were female. Two-dimensional echocardiography was used after 1978 in the initia...

Double-chambered right ventricle.

A19-year-old woman with mild exercise intolerance was referred for follow-up examination of a known ventricular septal defect (VSD; Figure 1A). By continuous-wave Doppler, a gradient across the tricuspid valve of 60 mm Hg was recorded. The parasternal short-axis view revealed an anomalous muscle bundle with insertion at the interventricular septum and the right ventricular (RV) free wall (Figur...
