“…Although absent pulmonary valve associated with tetralogy of Fallot is known to seriously compromise the airway during early infancy, that with intact ventricular septum has been described mostly in adults [2,10,13]. We are aware of only nine other patients who reportedly became symptomatic during the neonatal period [1, 3, 5-7, 9, 12, 14], all of whom had patent ductus arteriosus.…”

“…The clinical manifestations include a characteristic to-and-fro heart murmur, heart failure that is usually well tolerated, and prominent dilatation of the main pulmonary trunk on the chest radiograph. Compression of the airways, which is typical of infantile tetralogy of Fallot with an absent pulmonary valve, is not necessarily significant because the pulmonary dilatation may not involve the branch pulmonary arteries [2,3,10]. However, some cases of life-threatening distress have been reported in newborns [1, 3, 5-7, 9, 12, 14].…”

“…Absent pulmonary valve with intact ventricular septum is a rare congenital anomaly that manifests as isolated pulmonary valve incompetence with or without a pulmonary valve remnant [2,10]. The clinical manifestations include a characteristic to-and-fro heart murmur, heart failure that is usually well tolerated, and prominent dilatation of the main pulmonary trunk on the chest radiograph.…”

Absent Pulmonary Valve with Intact Ventricular Septum Presenting as Cardiorespiratory Failure at Birth

et al. 1997

Absent pulmonary valve with intact ventricular septum is a rare congenital anomaly. Most cases are not diagnosed until years after birth, although several cases have been reported in the literature in which cardiorespiratory distress developed during the neonatal period. We present a patient who showed improvement after fairly conservative therapy to alleviate the pulmonary vascular resistance, with ultimate palliative surgery. The aneurysmal dilatation of the pulmonary artery was for the most part confined to the proximal portion of the trunk, possibly because the ductus arteriosus was patent. The literature is reviewed.

Congenital absence of the pulmonary valve appears to have a prolonged fate, despite substantial regurgitation, thus the optimal timing of surgical correction remains unclear. A 53-year-old man with isolated pulmonary regurgitation accompanied by obstructive sleep apnea developed progressive heart failure after reopening of the foramen ovale. Closure of the interatrial shunt and pulmonary valve replacement with a 25-mm mechanical prosthesis relieved his refractory left heart failure.

“…This situation distorts the right ventricular outflow tract (6). Acquired IPVR is relatively uncommon and can be encountered under various clinical situation (7). The most common reason is surgical pulmonary valvulotomy or balloon dilatation to correct pulmonary valvular stenosis in tetralogy of Fallot patients (8).…”
