Question: Z score reference values for right ventricular size and systolic function in children using echocardiography are available in several countries. Despite the high burden of diseases involving the right ventricle in Nigeria, these reference values have limited applicability.
Finding: The right ventricular sizes of Nigerian children differed from those published elsewhere.
Meaning: These reference values will aid the treatment, monitoring, and pre- and postintervention for Nigerian children.
The improvement of right ventricular function after adenotonsillectomy in children with obstructive sleep apnea
Dong Yeop Kim, Kyung Ok Ko, Jae Woo Lim, Jung Min Yoon, Young Hwa Song, Eun Jeong Cheon
Clin Exp Pediatr. 2018;61(12):392-396.   Published online October 26, 2018

Purpose: Adenotonsillar hypertrophy (ATH) that causes upper airway obstruction might lead to chronic hypoxemic pulmonary vasoconstriction and right ventricular (RV) dysfunction. We aimed to evaluate whether adenotonsillectomy (T&A) in children suffering from obstructive sleep apnea (OSA) due to severe ATH could improve RV function. Methods: Thirty-seven children (boy:girl=21:16; mean age, 9.52±2.20 years), who underwent T&A forsleep apnea due to ATH, were...

Right ventricular failure in congenital heart disease
Young Kuk Cho, Jae Sook Ma
Clin Exp Pediatr. 2013;56(3):101-106.   Published online March 18, 2013

Despite developments in surgical techniques and other interventions, right ventricular (RV) failure remains an important clinical problem in several congenital heart diseases (CHD). RV function is one of the most important predictors of mortality and morbidity in patients with CHD. RV failure is a progressive disorder that begins with myocardial injury or stress, neurohormonal activation, cytokine activation, altered gene expression,...

Medico-Surgical Cooperative Treatment of Pulmonary Atresia with Intact Ventricular Septum
Kyeong Sik Kim, Byeong Chul Kweon, Jong Kyun Lee, Jae Young Choi, Jun Hee Sul, Sung Kyu Lee, Young Whan Park, Bum Koo Cho
Clin Exp Pediatr. 2003;46(3):250-258.   Published online March 15, 2003
Purpose : The actual clinical examples of co-appliance of catheter intervention with surgical procedures in the treatment of pulmonary atresia with an intact ventricular septum(PA/IVS) which we have experienced in our institution are here shown, and the anatomical and hemodynamical profiles between each method is compared. Methods : Medical records of 33 patients with PA/IVS who underwent various treatment from January,...
Effects of Main Pulmonary Artery Constriction on the Right Ventricle in Rabbits
Chan Uhno Joo, Dong Geun Lee
Clin Exp Pediatr. 1995;38(8):1087-1092.   Published online August 15, 1995
Purpose : constriction or banding of the pulmonary artery tocreate pulmonalry artery stenosis is a palliative procedure designed to limit pulmonary blood flow in congenital cardiac malformation with unrestricted shunt flow from the systemic to pulmonary circuit. Increased pressure-load with the procedure results in ventricular hypertrophy in right ventricle. We studied effects of the pulmonary artery constriction on the right ventricle...

Two Cases of Double-Chambered Right Ventricle by Abnomal Muscle Bundles
Hye Young Kang, Jung Il Noh, Jung Yun Choi, Yong Soo Yun
Clin Exp Pediatr. 1994;37(5):712-717.   Published online May 15, 1994
The double-chambered right ventricle is congenital or acquired cardiac anomaly, which is characterized by aberrent hypertrophied muscular bands that divide the right ventriclar cavity into two different pressure chamber. This anomaly can complicate the natural history of patient with isolated ventricular septal defect. We experienced two cases of acquired DCRV, which confirmed by two separate cardiac catherterization and angiography. The purpose...

Analysis of the Morphological Characteristics of Double Outlet Right Ventricle and Comparative Study of Operative Methods
Jun Hee Sul, Jong-Kyun Lee, Jo Won Jung, Sung Kyu Lee, Bum Koo Cho
Clin Exp Pediatr. 1993;36(12):1721-1731.   Published online December 15, 1993
Double outlet right ventricle, a complex of congenital cardiac anomalies in which both great arteries arise wholly or in large part from the morphologic right ventricle presents diverse clinical manifestations according to the morphological characteristics. Eighty cases with DORV were diagnosed and operated at Yonsei Cardiovascular Center from 1988 to 1992. The analysis of the morphological characteristics of this anomaly and...
Clinical and Hemodynamic Characteristics of Double Chambered Right Ventricle.

Clin Exp Pediatr. 1984;27(10):982-990.   Published online October 31, 1984
During the period from May 1981 to Feb. 1984, authors experienced 15 cases of double chambered right ventricle (D.C.R.V.) at Hanyang University Hospital. Among these 15 cases of D.C.R.V., 13 cases were confirmed by open heart surgery. We analysed the physical characteristics and echocardiographic, cardiac catheterization, angiographic and operative findings. Results are as follows; 1) Authors observations suggest that right ventricular obstructing...
Case Report
A Case Report of Double Outlet Right Ventricle(S.D.L.) with Subpulmonic Ventricular Septal Defect and Pulmonary Stenosis.
Jae Sun Jung, Sun Ok Park, Jung Yun Choi, Yong Soo Yun, Chang Yee Hong
Clin Exp Pediatr. 1984;27(4):407-412.   Published online April 30, 1984
Among the double outlet right ventricle, S.D.L. type with subpulmonic ventricular septal defect is extremely rare. We experienced 10 year old girl who had S.D.L. type of double outlet right ventricle with subpulmonic mitral valvular insufficiency and LV-RA canal. The literature were reviewed.

Clinical Observation of Double Outlet Right Ventricle.
In Suck Seo, Yong Soo Yoon, Chang Yee Hong
Clin Exp Pediatr. 1982;25(8):769-780.   Published online August 31, 1982
Eighteen cases of double outlet right ventricle were observed during past six years at the department of pediatrics, Seoul National University Hospital. 1. Therw were 13males and 5 females. Sex ratio showed male predominance with the ratio of 2, 6:1. 2. According to the Sondheimer's classification, 6 cases were in group l, none in group ll, 10cases in group lll...
