Persistent truncus arteriosus categories associated with different natural histories and various surgical approaches were reported. Although pulmonary overflow and severe heart failure are common, some patients who have hypoplastic pulmonary artery systems may show lesser symptoms of heart failure and remain in relatively stable condition. We experienced a 33-year-old woman with uncorrected type II persistent truncus arteriosus who presented with cyanosis rather than congestive heart failure, and are presenting her images.

The Truncus arteriosus is a congenital malformation in which only one great artery arises from the base of the heart and gives origin to the systemic, pulmonary and coronary arteries proximal to the aortic arch. Pulmonary blood flow is governed by the size of the pulmonary arteries and the pulmonary vascular resistance. In infancy, pulmonary blood flow is usually excessive because pulmonary vascular resistance is not greatly increased. Thus, despite an obligatory admixture of systemic and pulmonary venous blood in the common trunk, only minimal cyanosis is present. Rarely pulmonary blood blood flow is restricted by hypoplastic or stenotic pulmonary arteries arising from the truncus. The prognosis in persistent truncus arteriosus is very poor. the median age of survival of the 94 patients with the disease reported up to 1962 was only five weeks. The longest survival reported is the case of the man described by Carr et al who lived to the age of 36 years and 2 months. We report the case of a man with persistent truncus arteriosus who lives to the age of 29 years.

OBJECTIVETo recite early results and long-term outcomes after surgical repair of persistent truncus arteriosus (PTA).

METHODSThe clinic data of 54 patients underwent surgical repair for PTA from January 1999 to December 2009 was analyzed retrospectively. There were 36 male and 18 female patients, with a mean age of (9 ± 10) months (range, 1 to 38 months; median, 5 months). Preoperative mechanical ventilation was required in 5 patients. The surgical procedures were closure of ventricular septal defect and re-establishment of continuity between right ventricle and pulmonary artery. The right ventricular outflow tract (RVOT) was reconstructed by direct anastomosis pulmonary artery to right ventriculotomy with anterior wall patch enlargement (28 cases), or by inserting conduits (26 cases). Valvuloplasty were performed in 4 patients with truncal valves moderate to severe insufficiency and aortoplasty in 3 patients with interrupted aortic arch (IAA).

RESULTSThere were 3 patients (5.6%) died of pulmonary hypertensive crisis in hospital. The mean duration of ventilation was 6.8 days in 5 patients who were intubated before operation, while the others were 3.6 days. Forty-seven (92.2%) patients were followed-up for mean (6.8 ± 2.5) years (from 2.5 to 11.0 years). There were 2 patients with mild to moderate aortic regurgitation. One patient with aortic arch obstruction underwent balloon dilatation 2 years postoperatively. Among those patients who underwent direct anastomoses, 8 (32.0%) patients had pulmonary branch stenosis at 7 months to 1.5 years postoperatively, 12 (48.0%) patients were freedom from surgical reintervention 5.0 to 11.0 years postoperatively. Among those inserting conduits, 7 patients (31.8%) had conduit stenosis at 2.8 to 7.0 years after operation. Reoperations were performed for RVOT in 15 patients and there was no mortality.

CONCLUSIONSIt is difficult to treat the PTA patients with IAA, intra-mural coronary artery or mechanical ventilation support before operation. The technique of direct anastomosis between pulmonary artery and right ventricle offers the potential growth for RVOT, but bilateral pulmonary branch stenosis may be occurred at earlier period of postoperation in some patients.

OBJECTIVE: To analyze the spectrum of prenatally diagnosed congenital heart disease in a Korean population with 22q11.2 deletion syndrome, and to provide guidelines for screening 22q11.2 deletion prenatally. METHODS: This retrospective study evaluated 1,137 consecutive fetuses that had prenatal genetic testing for 22q11.2 deletion because of suspected congenital heart disease between September 2002 and December 2012, at Asan Medical Center, Seoul, Korea. RESULTS: Main cardiovascular diseases in the 53 fetuses with confirmed 22q11.2 deletions were tetralogy of Fallot (n = 24, 45%), interrupted aortic arch (n = 10, 19%), ventricular septal defect (n = 5, 9%), double outlet right ventricle (n = 4, 8%), and coarctation of the aorta (n = 4, 8%). Other cardiac defects were rarely associated with 22q11.2 deletion. One fetus had persistent truncus arteriosus, one had aortic stenosis, and one had hypoplastic right heart syndrome. Two fetuses had normal intracardiac anatomy with an isolated right aortic arch, and one had an isolated bilateral superior vena cava. CONCLUSION: A variety of congenital heart diseases were seen during the prenatal period. Conotruncal cardiac defects except transposition of great arteries were strongly associated with 22q11.2 deletion. When such anomalies are diagnosed by fetal echocardiography, genetic testing for 22q11.2 deletion should be offered. Even if less frequent deletion-related cardiac defects are detected, other related anomalies, such as thymic hypoplasia or aplasia, should be evaluated to rule out a 22q11.2 deletion.

Bicuspid aortic valve and/or coarctation of the aorta are consistently associated with ascending aortic and para-coarctation medial abnormalities. Medial abnormalities in the ascending aorta are prevalent in other types of patients with a variety of forms congenital heart disease (CHD), such as single ventricle, persistent truncus arteriosus, transposition of the great arteries, hypoplastic left heart syndrome, tetralogy of Fallot. These abnormalities encompass a wide age range, and may predispose to dilatation, aneurysm, and rupture that necessitates aortic valve and root surgery. This dilatation can develop in CHD patients without stenotic region. These CHDs exhibit ongoing dilatation of the aortic root and reduced aortic elasticity and increased aortic stiffness that may relate to intrinsic properties of the aortic root. The concept of aortic dilatation is shifting a paradigm of aortic dilatation, as so called post stenotic dilatation, to primary intrinsic aortopahy. These aortic dilatation and increased stiffness can induce aortic aneurysm, rupture of the aorta and aortic regurgitation, but also provoke left ventricular hypertrophy, reduced coronary artery flow and left ventricular failure. We can recognize this association of aortic pathophysiological abnormality, aortic dilation and aorto-left ventricular interaction as a new clinical entity: "aortopathy".
