Pulmonary Valve Reconstruction in Absent Pulmonary Valve Syndrome: A New Technique

Journal of Cardiac Surgery, 1997
In patients with absent pulmonary valve syndrome, the relief of the pulmonary regurgitation at the time of primary repair improves both the early and late results. Though homograft and heterograft valves and conduits have been used for this purpose, both are not easily available and are known for late failure.

The Pulmonary Valve

1985
The pulmonary valve has traditionally been considered the most difficult of the cardiac valves to record echo-cardiographically. These difficulties relate to (1) the normal position of the valve beneath the lingula of the left lung which restricts access of the exploring ultrasonic beam to the valve leaflets and (2) its plane of motion relative to the ...

The Pulmonary Valve

ASAIO Journal, 1994
Pulmonary autografts have shown a low incidence of early failure and late structural deterioration when placed in the aortic position yet the potential value of the pulmonary valve as a replacement device has not been widely considered. Since the mechanical suitability of pulmonary valves for the high stress aortic position is unclear, we set out to ...

Mechanical Pulmonary Valve Replacement

Seminars in Thoracic and Cardiovascular Surgery: Pediatric Cardiac Surgery Annual, 2016
Although most valve operations performed annually address lesions of the aortic or mitral valves, the frequency of pulmonary valve replacement (PVR) is increasing because most patients with congenital heart disease are surviving into the adult years. The vast majority of patients, especially children that require PVR, obtain a tissue valve because of ...

Percutaneous Pulmonary Valve Implantation

Seminars in Thoracic and Cardiovascular Surgery: Pediatric Cardiac Surgery Annual, 2009
Percutaneous pulmonary valve implantation is a new treatment option in patients with dysfunctional conduits. The aim of percutaneous pulmonary valve implantation is to prolong the lifespan of right ventricle to pulmonary artery conduits and thereby postponing open-heart surgery.

Pulmonary Valve Papillary Fibroelastoma

Heart, Lung and Circulation, 2009
A 67-year-old woman with a past history of hypertension and type 1 diabetes mellitus, complicated by ischaemic heart disease, retinopathy and nephropathy, presented with several months of worsening dyspnoea and clinical signs of right heart failure. Transthoracic echocardiogram (TTE) showed normal left ventricular systolic function with a restrictive ...

Congenital absence of the pulmonary valve

CardioVascular and Interventional Radiology, 1981
Congenital absence of the pulmonary valve (CAPV) is a rare anomaly usually associated with ventricular septal defect or Fallot's tetralogy. CAPV may be rapidly fatal in infancy because of severe disturbance of pulmonary ventilation resulting from bronchial compression by massively dilated pulmonary arteries. Other cases may be relatively benign.
