Obstructed infracardiac total anomalous pulmonary venous connection: The challenge of palliative stenting for the stenotic vertical vein.

ABSTRACT:

Introduction

Obstructed total anomalous pulmonary venous connection (TAPVC) is one of the commonest seen emergencies in pediatric cardiology centers.

Case presentation

Our case was diagnosed to have this anomaly, showing early respiratory distress resulting from severe pulmonary congestion. Palliative stenting of the obstruction was done, which helped in stabilizing the debilitated hemodynamics of the baby before surgery, thus a good surgical outcome and prognosis are expected.

Conclusion

This intervention may be listed as a vital measurement in the preoperative cardiac stabilization plan for infants with obstructed TAPVC.

Branching vertical vein with multiple sites of obstruction in supracardiac total anomalous pulmonary venous connection.

Project description:We present the case of an infant with total anomalous pulmonary venous connection and a branching vertical vein with multiple points of narrowing, draining the confluence into the innominate vein. The embryology and clinical relevance of this interesting anatomy is discussed.

The research on operation of obstructed total anomalous pulmonary venous connection in neonates.

Project description:OBJECTIVES: Total anomalous pulmonary venous connection (TAPVC) is a rare congenital heart disease. This study aimed to evaluate the outcomes of TAPVC repair in neonates, controlling for anatomic subtypes and surgical techniques. METHODS: Between 1997 and 2013, 88 patients (median age: 16 days) underwent repair for supracardiac (31), cardiac (18), infracardiac (36), or mixed (3) TAPVC. All the patients underwent emergency operation due to obstructed drainage. Supracardiac and infracardiac TAPVC repair included a side-to-side anastomosis between the pulmonary venous confluence and left atrium. Coronary sinus unroofing was preferred for cardiac TAPVC repair. RESULTS: The early mortality rate was 2.3% (2/88 patients). The echocardiogram showed no obstruction in the pulmonary vein anastomosis, and flow rate was 1.1-1.42 m/s in the 3-year follow-up period. CONCLUSIONS: The accurate preoperative diagnosis, improved protection of heart function, use of pulmonary vein tissue to anastomose and avoid damage of the pulmonary vein, and delayed sternum closure can reduce the risk of mortality. The preoperative severity of pulmonary vein obstruction, the timing of the emergency operation, and infracardiac or mixed-type TAPVC can affect prognosis. Using our surgical technique, the TAPVC mortality among our patients was gradually reduced with remarkable results. However, careful monitoring of the patient with pulmonary vein restenosis and the timing and method of reoperation should also be given importance.

Clarifying the anatomy and physiology of totally anomalous systemic venous connection.

Project description:The description of totally anomalous systemic venous connection is limited to case reports. In this review, we seek to clarify anatomic, physiologic, and hemodynamic aspects of this extremely rare anomaly. We also present findings of two patients in whom connection of all the systemic veins was anomalous. In the first patient, with usual atrial arrangement, all systemic veins, including the coronary sinus, were connected anomalously to the morphologically left atrium. Limited left-to-right shunt across an atrial septal defect provided the only source of blood flow to the lungs. The diagnosis was established by saline contrast echocardiography and cardiac catheterization. Extreme hypoplasia of the right ventricle precluded corrective surgery, so we performed a bidirectional Glenn operation, along with atrial septectomy. The second patient had isomerism of the left atrial appendages, which creates problems in the definition in anatomic terms since the connection of the systemic veins can never be normal anatomically when both atriums possess a morphologically left appendage. Our patient, nonetheless, had all the systemic and pulmonary veins, connected to the left-sided atrial chamber which then connected to the left ventricle, thus producing hemodynamics of totally anomalous systemic venous connection. We propose an algorithm for evaluation of this hemodynamic combination and discuss management options. We also intend to clarify the potential differences between connection and drainage, with particular attention to the arrangement of atrial appendages. Even though the hemodynamics may be comparable, in anatomic terms, both systemic and pulmonary venoatrial connection will always be anomalous with isomeric atrial appendages.

Interventional therapy for partial anomalous pulmonary venous connection with dual drainage.

Project description:A 6-year-old boy presented with dual drainage of left upper pulmonary vein, with connection to innominate vein inaddition to its normal connection to the left atrium. Despite relief of aortic stenosis at the age of 3 years, significant left to right shunt persisted. The dual drainage allowed successful percutaneous closure of the levoatriocardinal vein without obstruction to the pulmonary venous flow to the left atrium.

Next-generation sequencing identifies novel genes with rare variants in total anomalous pulmonary venous connection.

Project description:BACKGROUND:Total anomalous pulmonary venous connection (TAPVC) is recognized as a rare congenital heart defect (CHD). With a high mortality rate of approximately 80%, the survival rate and outcomes of TAPVC patients are not satisfactory. However, the genetic aetiology and mechanism of TAPVC remain elusive. This study aimed to investigate the underlying genomic risks of TAPVC through next-generation sequencing (NGS). METHODS:Rare variants were identified through whole exome sequencing (WES) of 78 sporadic TAPVC cases and 100 healthy controls using Fisher's exact test and gene-based burden test. We then detected candidate gene expression patterns in cells, pulmonary vein tissues, and embryos. Finally, we validated these genes using target sequencing (TS) in another 100 TAPVC cases. FINDINGS:We identified 42 rare variants of 7 genes (CLTCL1, CST3, GXYLT1, HMGA2, SNAI1, VAV2, ZDHHC8) in TAPVC cases compared with controls. These genes were highly expressed in human umbilical vein endothelial cells (HUVECs), mouse pulmonary veins and human embryonic hearts. mRNA levels of these genes in human pulmonary vein samples were significantly different between cases and controls. Through network analysis and expression patterns in zebrafish embryos, we revealed that SNAI1, HMGA2 and VAV2 are the most important genes for TAPVC. INTERPRETATION:Our study identifies novel candidate genes potentially related to TAPVC and elucidates the possible molecular pathogenesis of this rare congenital birth defect. Furthermore, SNAI1, HMGA2 and VAV2 are novel TAPVC candidate genes that have not been reported previously in either humans or animals. FUND: National Natural Science Foundation of China.

Pulmonary hypertension due to presence of isolated partial anomalous pulmonary venous connection: A case report.

Project description:Anomalous pulmonary venous return is an uncommon congenital malformation which can be broadly categorized into partial or total, of which the former is more common. The anomaly is considered to be partial if some of the pulmonary veins drain into the systemic circulation and total if all the pulmonary veins drain into systemic circulation. Isolated partial anomalous pulmonary venous return (PAPVC) is an uncommon finding and is a very uncommon cause of pulmonary arterial hypertension. Whilst many patients with PAPVC remain asymptomatic, some may present at a later age with symptoms related to left-to-right shunt, pulmonary hypertension and right heart failure. We are presenting an interesting case report of an 18 years old patient who presented with exertional dyspnea and fatigue conforming to NYHA class II symptom status. Trans-esophageal echocardiography revealed isolated obstructive PAPVC as the cause for pulmonary hypertension without other demonstrable left-to-right shunts.
