Fontan Surgery

Fontan operation is a reliable palliative surgery for patients with single ventricle physiology. Still, the development of complication is common; one of these complications that need to interventional approach is veno-venous collaterals between systemic and pulmonary veins. A 16-yearoldgirl with a history of modified Fontan operation at 9 years ago was referred with progressive cyanosis and dyspnea on exertion. In contrast trans-thoracic echocardiography (TTE), no fenestration was seen in Fontan circulation. Cardiac magnetic resonance revealed partial anomalous pulmonary vein connection (PAPVC) from left upper pulmonary vein to vertical vein and then into the in nominate vein and SVC with the reverse flow from superior vena cava (SVC) to left upper pulmonary vein(LUPV). This anomalous vein became severe engorged and tortuous. Possibly, LUPV and the verticalvein was dilated gradually as a result of increased pressure in the Fontan circuit. Finally, she underwent successful coil embolization in the midpart of the vertical vein. The oxygen saturation increased from80% to 93%.

Linear Ablation

Catheter ablation of long-standing persistent atrial fibrillation is not yet clearly defined with respect to endpoints, and different ablative strategies are offered to patients. Presented here is an approach aiming at biatrial debulking in the form of extensive linear ablation, specifically targeting areas of low-voltage complex fractionated electrograms, in addition to pulmonary vein isolation. Its main advantage is that it is not dependent on operator/system variability, since the strategy of isolating the pulmonary veins, superior vena cava and left atrial posterior wall together with achievement of bidirectional block during linear ablation provides objective endpoints that can consistently be reproduced.

Anomalous Pulmonary Venous Connection

Abstract Total anomalous pulmonary venous connection is a rare congenital heart defect. We report an infant with a mixed form of supracardiac TAPVC, in whom all pulmonary veins, except the right upper, entered a pulmonary venous confluence that is connected to a vertical vein and drained into the superior vena caval–right atrial junction. Several segmental right upper pulmonary veins entered the superior vena cava, superior to the entry of the vertical vein. Surgical repair consisted of the Warden procedure combined with direct anastomosis of the vertical vein to the left atrium. Separate pulmonary venous drainage pathways decreased the risk of post-operative pulmonary venous obstruction. Our patient had an uneventful post-operative course and encouraging 2-month follow-up echocardiography. Careful follow-up is warranted to detect post-operative complications, including obstruction of the pulmonary venous and cavoatrial anastomoses.

Anomalous Pulmonary Venous Return

Sinus venosus atrial septal defect (ASD) is usually associated with partial anomalous pulmonary venous return (PAPVR) of the right pulmonary veins to the superior vena cava (SVC), or to the SVC-right atrial junction. Standard procedure for repair of this defect is a patch roofing of the sinus venosus ASD and rerouting of pulmonary veins. However, the presence of SVC stenosis is a complication of this technique, and SVC augmentation is necessary in some cases. We present a simple technique for concomitant closure of sinus venosus ASD associated with PAPVR and augmentation of the SVC with a single autologous pericardial patch.

Here we report a case of a term newborn presenting with left palpebral ptosis, anisocoria and heterochromia as well as cleft palate and heart murmur. Congenital Horner syndrome was suspected and a thoracoabdominal CT scan was performed to rule out neuroblastoma. This revealed an anomalous drainage of right pulmonary veins to a collector that drains to the inferior vena cava, leading to the diagnosis of Scimitar syndrome. Echocardiogram showed an ostium secundum atrial septal defect, enlarged right chambers and a dilated coronary sinus due to a persistent left superior vena cava. The combination of Horner and Scimitar syndrome has never been described before. This case should encourage clinicians to use a multidisciplinary approach in order to guarantee an adequate diagnosis and management.

Abstract Background  Cough-induced atrial tachycardia (AT) is extremely rare and its electrical origin remains largely unknown. Atrial tachycardias triggered by pharyngeal stimulation, such as swallowing or speech, appears to be more common and the majority of them originate from the superior vena cava or right superior pulmonary vein (PV). Only one case of swallow-triggered AT with right inferior pulmonary vein (RIPV) origin has been reported to date. Case summary  We present a case of a 41-year-old man with recurring episodes of AT in the daytime. He underwent electrophysiology study without sedation. Atrial tachycardia was not observed when the patient entered the examination room and could not be induced with conventional induction procedures. By having the patient cough periodically on purpose, transient AT with P-wave morphology similar to the clinical AT was consistently induced. Activation mapping of the AT revealed a centrifugal pattern with the earliest activity localized inside the RIPV. After successful radiofrequency isolation of the right PV, AT was no longer inducible. Discussion  In the rare case of cough-induced AT originating from the RIPV, the proximity of the inferior right ganglionated plexi (GP) suggests the role of GP in triggering tachycardia. This is the first report that demonstrates voluntary cough was used to induce AT. In such cases that induction of AT is difficult using conventional methods, having the patient cough may be an effective induction method that is easy to attempt.

Abstract Background It has been reported that elimination of non-pulmonary vein (PV) triggers after PV isolation is a good predictor of atrial tachyarrhythmia free survival. However, precise mapping of triggers outside from superior vena cava (SVC) or left atrial posterior wall (LAPW) are difficult. The aim of this study is to assess the efficacy of self-reference mapping technique to eliminate non-PV triggers originated from outside of primordial pulmonary vein area. Methods Total of 431 patients (446 procedures) underwent atrial fibrillation (AF) ablation in a hospital and in a medical center from January 2017 to March 2019. After isolation of PV, non-PV triggers were induced with isoproterenol and/or adenosine triphosphate. Reproducible non-PV triggers were targeted to ablate using following self-reference mapping technique: A trigger conducts centrifugally and the earliest site should be distinguished from other later activated sites. Using a PentaRay multipolar catheter, the operators annotated the earliest site of local activation and a reference tag was placed. The multipolar catheter was then moved to the reference tag and the process repeated. Ultimately, we identified clusters of early circumferential activation and ablated. Results A total of 32 non-PV triggers excluding the origin from LAPW and SVC were induced in 23 patients. Nineteen triggers (59%) were located in the right atrium and 13 triggers (41%) in the left atrium (Figure 1). All triggers were eliminated with ablation and AF was non-inducible in all patients at the end of the procedure. During the follow-up (529±270 days), 18 patients (77%) were free from atrial tachyarrhythmias after a 3-month blanking period. Three patients received additional ablation procedures for recurrent atrial arrhythmias. No non-PV triggers ablated during the previous procedure were observed. Conclusion A novel self-reference mapping technique is useful for eliminating non-PV triggers in terms of the short- and long-term success. Figure 1.

Abstract Introduction The diagnosis of sinus venosus atrial septal defect (SVASD) is complex and requires special imaging. Surgery is the conventional treatment; however, transcatheter repair may become an attractive option. Case report A 60 year-old woman was admitted to the cardiology department with several episodes of paroxysmal atrial flutter, atrial fibrillation and atrioventricular nodal reentrant tachycardia. She reported a 10-year history of occasional palpitations which had not been studied. A transthoracic echocardiography revealed severe right ventricle dilatation and moderate dysfunction. Right volume overload appeared to be secondary to a superior SVASD with partial anomalous pulmonary venous drainage. A transesophageal echocardiography confirmed the diagnosis revealing a large SVASD of 16x12 mm (Figure A) with left-right shunt (Qp/Qs 2,2) and two right pulmonary veins draining into the right superior vena cava. Additionally, it demonstrated coronary sinus dilatation secondary to persistent left superior vena cava. CMR and cardiac CT showed right superior and middle pulmonary veins draining into the right superior vena cava 18 mm above the septal defect (Figures B and C). After discussion in clinical session, a percutaneous approach was planned to correct the septal defect and anomalous pulmonary drainage. For this purpose, anatomical data obtained from CMR and CT was needed to plan the procedure. During the intervention two stents graft were deployed in the right superior vena cava. The distal stent was flared at the septal defect level so as to occlude it while redirecting the anomalous pulmonary venous flow to the left atrium (Figure D). Control CT confirmed the complete occlusion of the SVASD without residual communication from pulmonary veins to the right superior vena cava or the right atrium (Figure E). Anomalous right superior and middle pulmonary veins drained into the left atrium below the stents. Transthoracic echocardiographies showed progressive reduction of right atrium and ventricle dilatation. The patient also underwent successful ablation of atrial flutter and intranodal tachycardia. She is currently asymptomatic, without dyspnea or arrhythmic recurrences. Conclusions In this case, multimodality imaging played a key role in every stage of the clinical process. First, it provided the diagnosis and enabled an accurate understanding of the patient’s anatomy, particularly of the anomalous pulmonary venous connections. Secondly, it allowed a transcatheter approach by supplying essential information to guide the procedure. Finally, it assessed the effectiveness of the intervention and the improvement in cardiac hemodynamics during follow-up. Abstract P649 Figure.

In a former communication we incidentally mentioned that in a rabbit killed by the injection of cobra-poison into the jugular vein we had observed the pulmonary vein pulsating after all motion had ceased in the cavities of the heart. We have since observed the same phenomenon three or four times under conditions which show that this pulsation is not due to the action of the cobra-poison with which the animal in which we first observed it had been killed. The following example will show the changes in rhythm observed in these pulsations. A cat was chloroformed, and the vagi exposed and irritated by an interrupted current. Artificial respiration was kept up by air containing chloroform vapour, and the thorax was then opened, and a solution of atropia injected directly into the heart by means of a Wood’s syringe. The vagi were again irritated, but without any effect being produced on the heart, the inhibitory apparatus in it being evidently paralyzed by the atropia. A solution of glycerine extract of physostigma was now injected into the heart in a similar way. The vagi were now irritated again, and the heart stood still, the effect of the atropia having been counteracted by the physostigma. After the irritation ceased the heart again commenced to pulsate.

The successful operations upon abnormalities of the outflow tracts of the heart suggest that surgical measures may also be applied to the correction of abnormal inflow tracts. Technically the anastomosis of veins to the auricle has been proved feasible in the experimental animal. Therefore, it should be possible to correct abnormally placed pulmonary veins in man. A wide variety of such anomalies occur. In 55 of 136 reported cases, all the oxygenated blood from the lungs was returned to the right heart through anomalous vessels. Thirty-five per cent of these cases of complete diversion were accompanied by other major cardiac defects. It is estimated that 50% or more of the return flow from the lungs must reach the right heart to produce clinical symptoms. Two cases are presented of persistence of the left superior vena cava which transmitted all the freshly oxygenated blood to the right auricle, by way of the left innominate and the right superior vena cava. The clinical picture was that of growth retardation, minimal cyanosis, a huge hyperactive heart, a loud left mesocardial systolic murmur, pulsating shadows in both upper pulmonary fields, and nearly identical oxygen-saturation of blood obtained from the right heart and femoral artery. One case is reported in which all the oxygenated blood from the lungs is carried to the right auricle by way of the ductus venosus. Surgical correction of the abnormality of these cases by transplantation of one or more of the veins would have been possible. However, no case known to the authors has yet been successfully corrected.
