Partial Anomalous Pulmonary Venous Return ( PAPVR ) is a rarified congenital disorderliness of the heart(1 ) .

The correct lung PAPVR is twice more common than the left lung PAPVR(1 ) .

What Happens To Untreated PAPVR?

PAPVR has an splendid medical prognosis for symptomless cases and there is no need for treatment in such cases . The peri - surgical mortality rate is < 0.1 % , which is comparable to the atrial septate defect . The prognosis decreases in individual who are not diagnosed for a long period and if complications pursue especially pulmonic hypertension . In pulmonary hypertensive female , there are danger during pregnancy that may let in death(1 ) .

When To Go To A Doctor For PAPVR?

Management is needed for symptomatic cases . adult with heart loser may be managed with water pill , genus Beta - blockers , and cardiac glycosides . Although , classical care for symptomatic PAPVR patients is surgical repair of the blemish ; however , there are contention regarding its meter reading . There are two schooling of cerebration ; one conceive that all baby with PAPVR should undergo surgical hangout due to very low mortality and unwholesomeness post - operating theater . The other school of persuasion believes that surgery should only be undertaken when there is significant left - to - right shunt ( Qp : Qs is 2:1 or greater ) or if an entire lung has unnatural pulmonic veins(1 ) .

The working proficiency reckon on the site of the abnormal vein / veins . The stamping ground technique for PAPVR to the superior vena cava ( SVC ) may either include intimate patch techniques with or without SVC expansion or Warden proficiency ( caval division proficiency with atriocaval anastomosis ) . It is of import to conform to up paediatric patients with intragroup patch technique for complications such as obstacle of the SVC with SVC syndrome , obstruction of the pulmonary veins , sick sinus syndrome , and supraventricular tachyarrhythmias(1 ) .

There is no dieting or activity / practice session limitation for the patients . However , patient should consult a cardiologist and cardiothoracic surgeon . It is of import to visit the cardiologist / cardiothoracic surgeon for a follow up as needed to supervise the right heart sizing , pressure , rhythm , and cardiac map in patients who did not choose for operative resort . Monitoring of atrial arrhythmia with ECG and 24 - hour ambulatory ECG should be done regularly as send by the MD . adult with unrepaired PAPVR may grow arrhythmias , cardiac failure , and on rare occasionspulmonary hypertension . In postoperative affected role , it is important to supervise for complication such as obstruction of the pneumonic veins and superior vein cava . Scimitar syndrome patients may either be asymptomatic or may germinate symptoms of lung pathology , such as recurrent pneumonia(1 ) .

Partial Anomalous Pulmonary Venous Return ( PAPVR ) is a rare congenital ( by giving birth ) heart disorder in which a few pneumonic vein blood is drained to the right atrium instead of the unexpended atrium . This leads to the flow of oxygenize rakehell from pulmonic veins to the deoxygenated systemic circulation . Generally , only a single pulmonary vein has a defect and it is only a rarified incidence in which all the pulmonary vein from one lung have a defect . PAPVR is very standardised to TAPVR ( Total Anomalous Pulmonary Venous Return ) , except in TAPVR all or most pulmonary mineral vein have an abnormal connector with the right atrium(1 ) .

Types Of PAPVR

The association of PAPVR is twice more common with the veracious lung than with the odd lung and unremarkably , PAPVR of veracious upper pulmonary mineral vein draining into the right atrium or the superscript vena cava ( SVC ) is see . In 80 - 90 % of the cases , this PAPVR is associated with atrial septal defect of sinus venosus type(1 ) .

The pulmonary vein can also enfeeble into the inferior vena cava ( IVC ) seen in Scimitar syndrome ( also known as Halasz syndrome , hypogenetic lung syndrome , innate pulmonary venolobar syndrome ) . It mostly involves the right lung that may show hypoplasia of the lung due to sequestered lobe of the lung , and dextrapositioning of the heart(1 ) .

Isolated PAPVR or PAPVR without atrial septal defect is also note , but it is quite rarified . PAPVR with complex inborn heart disease is affiliate with left atrial isomerism in which there is a common atrium(1 ) .
