Common Pulmonary Vein

Abstract A 4-hour-old infant with profound cyanosis on an alprostadil infusion was urgently transferred to Rady Children’s Hospital with suspected CHD. Upon arrival, urgent echocardiography was performed but could not confirm the presence of discrete pulmonary veins or pulmonary venous drainage. Given the difficulty in delineating the anatomy, a cardiac CT scan was performed and demonstrated a nearly atretic common pulmonary vein with multiple small collaterals that drained to systemic veins. Due to the high risk of mortality associated with operative repair, the decision was made to proceed with compassionate withdrawal of care. The described anatomy of common pulmonary vein atresia remains rare, and to our knowledge, fewer than 40 cases have been reported in the literature. Albeit rare, common pulmonary vein atresia should be considered in the differential diagnosis of a severely cyanotic neonate.

Abstract Background Scimitar syndrome consists of anomalous pulmonary vein drainage to the inferior vena cava. Its name derives from the image this anomalous pulmonary vein creates on a chest radiograph. We describe a case of normal venous pulmonary vein drainage that also presented the scimitar sign due to an aorto-collateral vessel. Case summary A 15-month-old girl presented with mild dyspnoea and fever. Control chest X-ray showed an image of cardiac dextroposition, hypoplastic right lung, and the ‘scimitar sign’. Although the transthoracic echocardiogram confirmed the initial suspicion of anomalous pulmonary venous drainage, the computed tomography (CT) scan showed normal right pulmonary veins connected to the left atrium and revealed that an aorto-collateral vessel caused the scimitar sign. Discussion Although the patient had several typical alterations of the scimitar syndrome, the pulmonary venous connection was normal, and the scimitar sign was due to an aorto-collateral vessel. It might be difficult to describe venous pulmonary connections on the basis of echocardiography, so an angio CT scan proved to be a valuable tool in this scenario.

Common Pulmonary Vein

The examination of serial sections of human embryos between 24 and 34 days (3 to 11 mm) and the use of plastic reconstructions, showed that the common pulmonary vein develops as an outgrowth from the medial superior wall of the left auricle and unites with the angioblastic plexus of the developing lung bud. No evidence was found that the vein connects directly with the sinus venosus in the early stages, and later shifts in position as the atrial septum grows. Anomalous pulmonary venous drainage is classified in four main types, and theories of development are briefly discussed.

Abstract Background Haemoptysis is an uncommon presenting symptom in children and is usually caused by acute lower respiratory tract infection or foreign body aspiration. We report a rare case of right unilateral pulmonary vein atresia (PVA) as the underlying aetiology of recurrent haemoptysis in a child. Case presentation A 4 years old girl presented with history of recurrent haemoptysis. Bronchoscopic evaluation excluded a foreign body aspiration but revealed right bronchial mucosal hyperaemia and varices. Diagnosis of right unilateral PVA was suspected on transthoracic echocardiography which demonstrated hypoplastic right pulmonary artery and non-visualization of right pulmonary veins. Final diagnosis was confirmed on cardiac CT angiography. A conservative treatment approach was opted with consideration for pneumonectomy in future when she is older. Conclusion Rarer causes should be considered when investigating for recurrent haemoptysis in children. Bronchoscopy and cardiac imaging are useful tools to establish the diagnosis of unilateral PVA in our case.

Abstract Background Variations in pulmonary venous anatomy should not be undermined by thoracic surgeons during procedures which involve the pulmonary veins. Methods We have identified vascular anomalies in 25 of 346 patients undergoing video-assisted thoracoscopic surgery lobectomy at our Thoracic Surgery Unit, between December 2016 and November 2018. Results Some vascular anomalies described have not been reported in recent literature and include right V7 draining into the middle lobe pulmonary vein, accessory right V6 behind the bronchus intermedius, two V6 from the apical segment of left lower lobe, two V6 from the apical segment of right lower lobe, and one of them draining into the superior pulmonary vein. Conclusion Thoracic surgeons should be aware of this type of anomalies because failure in the preoperative or intraoperative identification of the pulmonary venous variations may lead to serious complications.

Objectives The aim of the study was to provide a detailed anatomical study of the feline bronchial and vascular structures by using CT angiography (CTA). Methods Adult cats with no respiratory clinical signs were enrolled in a CTA protocol to provide an anatomical study of the thorax. The dimensions, number of branches and branching pattern (monopodial vs dichotomic) of both bronchial and pulmonary vascular structures were evaluated under positive inspiration apnoea. A linear generalised estimating equations analysis (Spearman’s rho) was used to identify statistical correlation between tracheal diameter, age and body weight of the cats. Results Fourteen cats met the inclusion criteria. The pulmonary arteries had larger diameters than the pulmonary veins, and the pulmonary veins had larger diameters than the bronchial structures. A higher number of segmental bronchial and pulmonary vascular branches was observed in the left caudal lung lobe than in the other lobes. The monopodial branching pattern of both bronchial and pulmonary vascular structures was predominant in all cats of our study (100%) in cranial, caudal and right middle lung lobes, while a dichotomic branching pattern of the bronchial and pulmonary vascular structures of the accessory lung lobe was seen in 13 cats (93%). Thirteen cats (93%) had three pulmonary vein ostia, and one cat (7%) also presented with an additional left intermediate pulmonary vein ostium. Variation in the number of segmental pulmonary vein branches was noted in the right caudal lung lobe. There was no statistical correlation between tracheal diameter, age and weight. Conclusions and relevance Architecture of the feline bronchovascularr structures belongs to a mixed type of monopodial and dichotomic branching pattern. In cats, the pulmonary venous drainage system predominately presents three pulmonary vein ostia. Variations in the type of formation and the number of branches of the pulmonary venous drainage system were noted.

Second-generation cryoballoon (CB2) - based pulmonary vein isolation (PVI) has demonstrated encouraging clinical results in the treatment of paroxysmal (PAF) and persistent atrial fibrillation (PersAF). Nevertheless, the acute efficacy, safety, and long-term clinical results of CB2-based PVI in patients with a left common pulmonary vein (LCPV) are still a matter of debate. Commented paper by Heeger ChH, et al. analyzes this issue with some practical conclusions.

The Impact

Background: This study aims to determine the impact of pre-procedural cardiac computerized tomography (CT) on procedural efficacy, clinical outcome and complications in patients who undergo radiofrequency or cryo-therapy catheter ablation to eliminate atrial fibrillation (AF). Methods: In this retrospective review, Radiofrequency or Cryoballoon ablation was done on 50 consecutive patients with atrial fibrillation with mean age of 63 (Min 47-Max 86) with paroxysmal (8 2 %) or persistent (18%) AF. Twenty-five patients underwent cryoablation and twenty-five patients underwent Radiofrequency ablation to isolate the pulmonary veins. Procedural and clinical outcomes were compared among patients who underwent catheter ablation with and without pre procedural Cardiac CT. Results: Out of 50 consecutive patients between 01/2014 and 08/2014 there were 26 patients who had a pre-procedural CT scan and 24 patients who did not undergo a pre-procedural CT scan. The mean duration of the procedure (303 ± 93 vs. 271 ± 43 min, P = 0.244) and fluoroscopy time (53 ± 25 vs. 43 ± 17 min, P = 0.086) was similar among patients who did and did not have pre-procedural cardiac CT. The occurrence of complications such as bleeding, pericardial tamponade, pneumothorax, infection and embolic events were also similar in both groups. Repeat ablation was performed in 4 (15%) and 7 (29%) of the patients who did and did not have cardiac CT, respectively (P = 0.249). At 3 months, 5 (19%) and 2(8%) of the patients who did and did not have pre-procedural cardiac CT had atrial fibrillation recurrence (P =0.323). At 12 months, 6 (23%) and 4 (17%) of the patients who did and did not have pre-procedural cardiac CT had atrial fibrillation recurrence (P = 0.467). There was statistically significant difference in Radiation exposure (1805 [IQR 998-2397] vs. 1195 [IQR 738-1363] P=0.0323) between patients who did and did not get pre-procedural cardiac CT, which did not include the radiation added by performing the CT itself. Conclusions: Pre-procedural structural anatomy obtained by cardiac CT scan before catheter ablation for atrial fibrillation in a center where operators used both Radiofrequency and Cryoablation does not appear to have a significant effect on AF recurrence at 3 months or 1 year. The procedural radiation exposure was significantly less in the group that did not have pre-procedure cardiac CT.

Abstract 40 year-old male with history of congenital heart disease. Atrial septal defect (ASD) sinus venosus type associated with partial anomalous pulmonary venous drainage (PAPVD) was diagnosed during childhood and surgically repaired at the age of three. Since then the patient was asymptomatic and he was lost to follow up when reached adulthood. A transthorathic echocardiogram was performed during a hospitalization because of a complicated pneumonia. A severe dilatation of right chambers and main pulmonary artery was observed. The estimated Qp:Qs by this technique was 2.0 but the atrial septum seemed to be intact. Agitated saline was administered in this procedure and no passage of microbubbles was observed. A cardiac MRI was performed because of suspicion of anomalous pulmonary venous drainage. The findings observed in the echocardiogram were confirmed and an uncommon PAPVD was demonstrated by this technique: the superior left pulmonary vein drainaged into a dilated innominated vein. Also, a small pulmonary vein from the right upper lobe emptied into a "venous conduct" (yellow circle) located posterior to the superior cava vein (SCV) that later drainaged into the right atrium under the mouth of the SVC, posterior to the interatrial septum. Surgically correctioin of the PAPVD was performed. Discussion PAPVD is a congenital heart disease characterized by the drainage of one or several pulmonary veins –but not all of them- into the right atrium or systemic veins, which leads to left-to-right shunting. The estimated incidence of this disease ranges between 0.1 and 0.2% of the general population. The right superior pulmonary vein is the most frequently involved and is commonly associated to ASD sinus venosus type. Bilateral anomalous drainage, as occurred in this case, is exceptional. Furhermore, this case highlights the importance of long-term follow-up in patients with congenital heart disease due to the fact that, even when the disease is considered to be cured, long term complications could appear compromising the prognosis of the patient.

Common Pulmonary Vein

Among the causes of pulmonary venous obstruction is atresia of the common pulmonary vein. This entity is described in three patients. The anatomic abnormality in these patients was the absence of any functional connection between the pulmonary veins and the left atrium, and anomalous pulmonary venous connection in the usual sense was not present. The results of the severe pulmonary venous obstruction imposed by this abnormality are reflected clinically in severe cyanosis, congestive cardiac failure, and early death. Roentgenograms revealed the diffuse reticular pattern in the pulmonary fields associated with pulmonary venous obstruction. Angiocardiographic techniques permit anatomic diagnosis of this cardiac abnormality and allow its differentiation from the other cardiac abnormalities responsible for pulmonary venous obstruction. Because the cul-de-sac-like confluence of the pulmonary veins is of ample size and lies immediately behind the left atrium, surgical relief of this condition seems possible.
