Double-Inlet Left Ventricle Before and After Septation
نویسندگان
چکیده
Septation is one of the surgical choices for double-inlet left ventricle, yet postoperative hemodynamics have not been well defined. We studied ventricular volume characteristics in 10 patients with double-inlet left ventricle before and after septation. Preoperative end-diastolic volume (EDV) of the ventricle was 291±111% (±SD) of normal and ejection fraction (EF) was 0.59± 0.07. Postoperatively, EDV of the right-sided ventricle (RV) was 82+24%, and EDV of the left-sided ventricle (LV) was 153+±41%. Ejection fraction of the RV was 0.77+0.10, and LVEF

Staged septation of double inlet left ventricle.
Complete septation of a double inlet left ventricle with left anterior subaortic outlet chamber was carried out successfully as a staged procedure during the first two years of life in a patient with severe pulmonary hypertension and an abnormal left atrioventricular valve. In contrast with isolated pulmonary artery banding, which rarely has led to a satisfactory septation or modified Fontan op...

Septation is one of the surgical choices for double-inlet left ventricle, yet postoperative hemodynamics have not been well defined. We studied ventricular volume characteristics in 10 patients with double-inlet left ventricle before and after septation. Preoperative end-diastolic volume (EDV) of the ventricle was 291 +/- 111% (+/- SD) of normal and ejection fraction (EF) was 0.59 +/- 0.07. Pos...
متن کاملFontan completion after external stenting of the left bronchus and intrapulmonary artery septation for left pulmonary artery hypoplasia.
Tracheobronchial obstruction and unilateral hypoplasia of the pulmonary artery are serious barriers to successful Fontan completion. We describe a 5-year old girl with left bronchial obstruction, hypoplasia of the left pulmonary artery and a single ventricle (double inlet left ventricle). She had undergone external stenting to treat left bronchial stenosis at 3 years of age, bidirectional cavop...
متن کاملThe New Concept of Univentricular Heart
The concept of univentricular heart moved from hearts with only one ventricle connected with atria [double inlet ventricle or absent atrioventricular (AV) connection] to hearts not amenable to biventricular repair, namely hearts with two ventricles unable to sustain separately pulmonary and systemic circulations in sequence. In the latter definition, even hearts with one hypoplastic ventricle a...
متن کاملDouble inlet right ventricle. Two pathological specimens with comments on embryology.
This paper describes two pathological specimens of congenital heart disease with double inlet right ventricle in which the ventricular chamber receives the right atrioventricular ostium and partially the left atrioventricular ostium, the two atrioventricular ostia being completely separated. The published reports are reviewed and only cases of double inlet left ventricle have been found. An ont...
