The arterial switch operation (Jatene procedure) is the treatment of choice for transposition of the great arteries with intact ventricular septum (TGA-IVS) in neonatal age, because of the low mortality and morbidity during long term follow up. Right ventricular outflow obstruction is the most frequent postoperative complication, occurring with suYcient severity to require reintervention in up ...

The width of the jet flow in the pulmonary artery was measured using a multigate pulsed Doppler system in a baby with severe pulmonary valve stenosis. The degree of stenosis estimated before operation agreed with the result obtained during surgery.

background total correction of tetralogy of fallot (tof) anomaly in early childhood has been practiced in many centers with good results, but in some of patients after few years sever pulmonary valve insufficiency occurred. materials and methods at a cross- sectional study from january 2015 to january 2016, 10 patients who had history of primary repair of tof with free pulmonary insufficiency (...

no commissural fusion. The obstructive mechanism is related to markedly thickened, immobile cusps, characterized by the presence of disorganized myxomatous tissue. Several clinical features tend to distinguish this form of pulmonary stenosis. In each of 16 patients studied, a pulmonary ejection murmur was present, but this was not associated with an ejection click. Other features suggestive of ...

The study has focused on the retrospective analysis of cases of coexisting congenital aortic stenosis (AS) and pulmonary artery stenosis (PS) in dogs. The research included 5463 dogs which were referred for cardiological examination (including clinical examination, ECG and echocardiography) between 2004 and 2014. Aortic stenosis and PS stenosis were detected in 31 dogs. This complex defect was ...

BACKGROUND Carcinoid tumor with consecutive endocardial fibroelastosis of the right heart, known as carcinoid heart valve disease (CHVD) or Hedinger's syndrome, is accompanied by combined right-sided valvular dysfunction with regurgitation and stenosis of the affected valves. Cardiac surgery with replacement of the tricuspid and/or pulmonary valve is an established therapeutic option for patien...

This lecture is based on a review of my experiences in the treatment of 198 patients with pulmonary valve stenosis, a condition that has occupied a great deal of my attention during the last twelve years. I hope that it will be of value to you even though it deals with a subject with which we are all familiar today. The term pulmonary stenosis is, of course, a generic one for all types of the c...

LEOPARD syndrome is an autosomal dominant genetic disorder involving a complex of malformations and other features, including lentiginosis, electrocardiographic conduction abnormalities, ocular hypertelorism, pulmonary valve stenosis, abnormal genitalia, growth retardation, and sensorineural deafness. The most common cardiovascular manifestations of this condition are pulmonary valve stenosis, ...

A bicuspid aortic valve (BAV) demonstrating moderate valvular stenosis and mild insufficiency was identified in an asymptomatic 1-year-old male cryptorchid English bulldog by transthoracic and transesophageal echocardiography. The BAV was most consistent with type 3 morphology, based upon human classification. Pulmonary valve dysplasia with mild pulmonary stenosis and a suspected persistent lef...

BACKGROUND Pulmonary artery intimal spindle cell sarcomas are rare and carry with them a poor prognosis and high rate of recurrence. In extremely rare cases, this tumor can infiltrate the pulmonic valve and manifest as adult-onset pulmonic stenosis. CASE PRESENTATION We report an unusual case of a patient with symptomatic, adult-onset severe pulmonic stenosis who was referred for possible bal...
