Abstract
Persistent left superior vena cava is rare and asymptomatic and is usually discovered incidentally during or after insertion of a central venous catheter. There is uncertainty as to whether or not the catheter should be removed after its malposition resulting in persistent left superior vena cava. We reported an unusual case of a breast cancer patient with a persistent left superior vena cava detected after a peripherally inserted central catheter insertion. The patient had undergone a modified radical mastectomy and needed to insert a peripherally inserted central catheter for chemotherapy. After the peripherally inserted central catheter insertion, the chest X-ray and computed tomography showed that the catheter was located in the persistent left superior vena cava. After an assessment of the persistent left superior vena cava and the catheter tip position, the peripherally inserted central catheter remained in the persistent left superior vena cava for further therapy. To ensure the integrity of the catheter, special follow-ups and tip position observations were carried out. The peripherally inserted central catheter was safe until the end of chemotherapy with no complications. Although the peripherally inserted central catheter tip was located in persistent left superior vena cava, given that the persistent left superior vena cava coexisted with a right superior vena cava with the similar lumen, the peripherally inserted central catheter could be used normally under strict attention.

Abstract
Background Cardiac tamponade is one of the most serious complications when performing cardiac interventions. Although most of the patients can be treated effectively using pericardiocentesis, urgent surgery can be necessary in case of continuous bleeding and patients’ haemodynamic impairment. Case summary With this unique clinical case report we describe an acute endovascular occlusion of a cardiac perforation utilizing the inflated 28 mm cryoballon at the transseptal puncture site close to the superior part of the coronary sinus ostium in a patient with persistent left superior vena cava (PLSVC) and severe post-procedural tamponade. Prior to this maneuver, 1200 mL of haemorrhagic effusion has been aspirated. Forty-five minutes after cryoballoon-guided occlusion we deflated the balloon and no additional blood could be aspirated over the following 20 minutes. Discussion Cryoballon-guided occlusion of the perforation site saved the patient from immediate cardiac surgery and resulted in stable haemodynamic conditions. This bailout approach was transferred from coronary interventions where occlusion of a perforated vessel using balloon devices is a common technique to achieve acute hemostasis.

Abstract
Accessory breast cancer with persistent left superior vena cava(PLSVC) is rare. The treatments of axillary accessory breast cancer should attract our attention. Patients with accessory breast cancer without breast invasion should undergo local enlarged resection and axillary lymph node dissection (ALND). We recommend routine axillary radiotherapy after accessory breast cancer surgery. It is imperative to organize multi-center accessory breast cancer research.
Introduction Axillary accessory breast cancer and persistent left superior vena cava (PLSVC) are rare clinically. Many controversial treatments for accessory breast cancer are worth discussing and learning. Presentation of the case A 48-year-old woman presented with biopsy histopathology confirmed. Right axillary mass biopsy pathology showed mucinous adenocarcinoma of accessory breast. She concerned that the axillary accessory breast cancer was more likely to metastasize and unsure about whether to remove the breast. She accepted extended right axillary accessory breast resection plus ipsilateral axillary lymph node dissection (ALND) and received chemotherapy. She was found to have a PLSVC before chemotherapy. Discussion Is there a need to remove the breast and perform ALND during axillary accessory breast cancer surgery? Is sentinel lymph node biopsy (SLNB) appropriate for axillary accessory breast cancer surgery? Can negative SLNB for axillary accessory breast cancer avoid ALND? Does accessory breast cancer without axillary lymph node metastasis require local radiotherapy? Does PLSVC impact the use of peripherally inserted central catheters (PICC) tubes during chemotherapy? Patients with accessory breast cancer without breast invasion should undergo local extended resection and ALND. SLNB for accessory breast cancer cannot instead of ALND. We recommend routine axillary radiotherapy after accessory breast cancer surgery. If it is determined that the tip of PICC is not in the coronary sinus of PLSVC, PLSVC does not affect chemotherapy. Conclusion Many treatment strategies for accessory breast cancer require more evidence from evidence-based medicine. It is imperative to conduct multi-center accessory breast cancer research.

Abstract
Persistent left superior vena cava is a rare congenital anomaly, occurring in 0.3% to 0.5% of general population and up to 10% in patients with congenital heart disease. This anomaly is usually discovered incidentally during central venous catheterization from left side. Since 2015, we have identified eight cases of persistent left superior vena cava out of a total of 2637 patients who had left sided venous port insertion in our department. The persistent left superior vena cavae were identified with the aid of intracavitary electrocardiogram. The characteristic finding was an initial negative P-wave (in lead II), followed by a biphasic P-wave pattern during catheter insertion. All the ports worked properly, with a total catheter dwelling time of 2586 days (range: 96-756 days, mean: 323.25 days), and no catheter-related complication was observed. However, because of the paucity of clinical evidence, we should still be prudent in the long-term use of venous ports in persistent left superior vena cava.

Abstract
Persistent left superior vena cava (PLSVC) is the most common variation of anomalous venous return to the heart and present in 0.1–0.5% of the general population. The left anterior cardinal veins typically obliterate during early cardiac development but failure of involution results in PLSVC. It is an asymptomatic congenital anomaly, usually discovered while performing interventions through the left subclavian vein or during cardiovascular imaging. PLSVC can be associated with cardiac arrhythmias and congenital heart disease. We present two cases of PLSVC: first, a 68-year-old male who presented with complete heart block, for which a temporary pacemaker was initially inserted followed by a permanent pacemaker; second, a 53-year-old female with a history of hypertension and ischemic cardiomyopathy with a left ventricular ejection fraction of 25%, and a survivor of sudden cardiac death, who underwent an implantable cardioverter-defibrillator (ICD) for secondary prevention. Both cases of PLSVC were detected incidentally during the transvenous approach to the heart. PLSVC was suspected by the unusually left medial position of the lead, while cineflouroscopy showed the venous trajectory toward the coronary sinus and drainage into the right atrium. It is technically difficult to cross the wire through the tricuspid valve when coming from the PLSVC and coronary sinus without making a loop in the right atrium, which is known as a wide loop technique. PLSVC is an uncommon anomalous anatomical variant and should be recognized appropriately by specialists who frequently carry out procedures through the left subclavian vein, such as implantation of permanent pacemaker, ICD and cardiac resynchronization therapy. It should also be recognized that wide loop formation of the right ventricular lead in the right atrium is helpful to cross the tricuspid valve and to affix the lead in the right ventricle.

Abstract
BACKGROUND Although congenital vena cava (CVC) anomalies in adults have implications for surgical and radiological interventions, the literature is scare and disparate. The aim of this systematic review was to assess cardiovascular clinical and procedural implications of CVC anomalies in adults without congenital heart disease. METHODS AND RESULTS We searched PubMed and EMBASE from database conception through October 2018 for English-language studies describing the epidemiology of CVC anomalies or their clinical or procedural implications in humans. Two independent reviewers screened 7093 records and identified 16 relevant studies. We found two major implications of CVC anomalies: 1) congenital inferior vena cava (CIVC) anomalies are associated with a 50-100-fold higher risk of deep venous thrombosis, particularly among younger patients, and 2) persistent left superior vena cava (PLSVC) is associated with a 2-3-fold higher risk of supraventricular arrhythmias. PLSVC also poses technical challenges to cardiovascular electronic device implantation, requiring alterations in surgical approach and lengthening procedure and X-ray exposure times. Due to the large disparity in reported prevalence rates of CIVC anomalies, we performed a meta-analysis of CIVC anomaly prevalence including 8 studies, which showed a weighted prevalence of 6.8% (95% CI, 4.5-9.2%). CONCLUSION These findings challenge the notion that CVC anomalies are rare and asymptomatic in adults. Rather, the literature indicates that CVC anomalies are not uncommon and have important clinical and procedural implications. To further understand the prevalence and implications of CVC anomalies, a robust US population-based study and nationwide registry is warranted in the current era of venous interventions.

Abstract
BACKGROUND Persistent left superior vena cava is a not uncommon congenital vascular abnormality. We report a case of heart transplantation with reconstruction of persistent left superior vena cava using a prosthetic vascular graft. CASE PRESENTATION A 20-year-old man with idiopathic dilated cardiomyopathy and persistent left superior vena cava underwent orthotopic heart transplantation 2 years and 3 months after left ventricular assist device implantation. Because the persistent left superior vena cava had a larger diameter than the right superior vena cava, the transected persistent left superior vena cava was reconstructed with a prosthetic vascular graft anastomosed to the free wall of the right atrium. Postoperative enhanced computed tomography revealed good patency of the graft. The patient's postoperative course has been uneventful during 2 years of follow-up, despite the risk of complications. CONCLUSIONS Reconstruction of a persistent left superior vena cava with a prosthetic vascular graft may be one option at the time of heart transplantation.

Abstract
Persistent left superior vena cava (PLSVC) is one of the cardiac system abnormalities with a 0.3-0.5% incidence and caused by inadequate obliteration of the left anterior cardinal vein during embryonic development. Prognosis of PLSVC is generally assumed to be good if it is not accompanied by other cardiac system abnormalities. During the routine ultrasound control of a patient at 25th week of pregnancy at the Obstetrics and Gynecology Department of Mersin University, PLSVC anomaly was detected in an intrauterine fetus. Then, intrauterine death occurred and after removal of the deceased fetus, PLSVC diagnosis was confirmed by autopsy. According to the autopsy findings, right superior vena cava (SVC) and azygos vein were found in normal course. PLSVC opened into the right atrium via enlarged coronary sinus. There was no connection between the two SVCs. On the left side of posterior mediastinum, instead of hemiazygos or accessory hemiazygos veins, a vein symmetrical to azygos was opened into PLSVC, similar to the one on the right. No other cardiac anomaly associated with PLSVC or any other pathology in the other parts of body that could be responsible for death was discovered during autopsy. There was no evidence indicating that PLSVC played any role in intrauterine exitus of the present case. However, as mentioned in the literature, the ectopic beats in the atrium wall of patients with isolated PLSVC and enlarged coronary sinus may lead to pathologies in the conduction system of the heart. Considering the intrauterine death of an isolated PLSVC case associated with cardiac conduction pathologies, we recommend that the common assumption of 'isolated PLSVC is not associated with death' should be reviewed by studies on large series and even intrauterine cases should be closely monitored for cardiac arrhythmia.

Abstract
The frequency of chromosomal anomalies among fetuses with isolated persistent left superior vena cava (PLSVC) is still debated. The objective of the present study was to assess the prevalence of genetic and morphological anomalies identified in fetuses with PLSVC. We conducted a single-center retrospective study including all fetuses diagnosed with a PLSVC between 2010 and 2017. PLSVC was categorized as isolated or associated according to antenatal diagnosis of associated congenital heart defects, hypoplastic aortic isthmus, abnormal venous/arterial connections, and extracardiac anomalies. Among 229 fetuses diagnosed with PLSVC, 39 cases (17%) were strictly isolated and no syndromic/genetic anomaly or aortic coarctation was diagnosed. Seventy-two fetuses had a cardiovascular defect with a rate of genetic anomalies of 22%, 29 had an extracardiac malformation, and 89 had both an extracardiac and a cardiovascular defect. Among fetuses with abnormal development of the arterial/venous system as the only associated anomaly such as aberrant right subclavian artery or absent ductus venosus, 22% had a genetic anomaly. Overall, sixty-five fetuses or infants had a genetic concern, including 23 aneuploidies, 15 pathogenic micro-deletions/duplications, and 5 variants of unknown significance; 12 patients had VACTERL association, and 12 heterotaxy syndrome. Seven infants had an aortic coarctation diagnosed at birth.In conclusion, a thorough prenatal ultrasound examination is paramount, and the identification of variants of the venous/arterial system in addition to PLSVC should raise suspicion for genetic or morphologic abnormalities. Invasive prenatal diagnosis with array-CGH should be offered when PLSVC is non-isolated, after a detailed ultrasound evaluation in a tertiary center.

Abstract
AIMS The impact of persistent left superior vena cava (PLSVC) in atrial fibrillation (AF) patients undergoing radiofrequency catheter ablation (RFCA) is not well known. We performed this analysis to evaluate the electrophysiological characteristics of PLSVC and its role in triggering and maintaining AF. METHODS AND RESULTS Patients with AF referred to two tertiary hospitals were screened and patients with PLSVC in pre-RFCA imaging studies were enrolled. Among 3967 patients, PLSVC was present in 36 patients (0.9%). There were four morphological types of PLSVC: type 1, atresia of the right superior vena cava (SVC) (n = 2); type 2A, dual SVCs with an anastomosis between right and left SVCs (n = 15); type 2B, dual SVCs without an anastomosis (n = 16); type 3, PLSVC draining into the left atrium (LA; n = 2); and unclassified in one patient. Thirty-two patients underwent RFCA and electrophysiology study focusing on PLSVC: PLSVC was the trigger of AF in 48.4% of patients and the driver of AF in 46.9% of patients. Cumulatively, PLSVC was a trigger or driver of AF in 22 patients (68.8%). Whether to ablate PLSVC was determined by the results of electrophysiology study, and no significant difference in the late recurrence rate was observed between patients who did and did not have either trigger or driver from PLSVC. CONCLUSION Pre-RFCA cardiac imaging revealed PLSVC in 0.9% of AF patients. This study demonstrated that PLSVC has an important role in initiating and maintaining AF in substantial proportion of patients. Electrophysiology study focusing on PLSVC can help to decide whether to ablate PLSVC.

Abstract
Coronary sinus ostial atresia is rare and usually not clinically relevant, but it should be noted in cases of cardiac resynchronization therapy. A rare case of successful left ventricular lead implantation for cardiac resynchronization therapy via the left superior vena cava in a patient with coronary sinus ostial atresia is reported. The persistent left superior vena cava associated with these cases tends to be smaller than usual in its diameter and difficult to identify, since the direction of venous drainage is reversed. Therefore, in the present case, it was useful to use a small-diameter, soft inner catheter as a guiding catheter to perform selective imaging and avoid vascular injury. In addition, it appeared to be important to plan the surgical strategy using prior imaging information, since it would be difficult to obtain the backup needed for lead insertion. 〈 Learning objective: Cardiac resynchronization therapy via the left superior vena cava with coronary sinus ostial atresia is generally possible without problems if prior imaging information is available, such as three-dimensional computed tomography and the venous phase of coronary angiography. It is important to determine whether there is a persistent left superior vena cava before the procedure. Thromboprophylaxis remains controversial in this situation.〉

Abstract
Background Persistent left superior vena cava (PLSVC) is a common vena cava malformation, and drains blood into the right atrium via the dilated coronary sinus in most cases. It is usually asymptomatic and detected incidentally during invasive procedures or imaging. Whether the hemodialysis catheters can be placed in PLSVC is still controversial now (Stylianou et al. Hemodial Int 11:42-45, 2007). Case presentation Here we report a rare case of catheterization through PLSVC in an end-stage renal disease (ESRD) male patient whose PLSVC connected with pulmonary vein with insufficient blood flow eventually. Among the other 28 cases included in the literature review, 16 cases were non-tunneled catheter and 12 cases were cuffed, tunneled catheter and most of them could provide adequate blood flow. Conclusion PLSVC is a rare malformation and mostly asymptotic, we believe that PLSVC drains blood into the right atrium with enough inner diameter and blood flow can serve as an alternative site for conventional dialysis access. However, the feasibility of hemodialysis catheterization through it and measures to avoid serious complications are still needed to be discussed.

Abstract
BACKGROUND Persistent left superior vena cava (PLSVC) is a rare congenital vascular anomaly. Permanent pacemaker implantation (PPI) in patients with PLSVC can be challenging because of the venous anomalies. We reported a case series of patients with PLSVC who underwent PPI with double active fixation leads. METHODS From January 2012 to July 2016, 9 patients (three male and six females, mean age 68 ± 11 years) with PLSVC who received a dual-chamber pacemaker with double active fixation leads were enrolled retrospectively in this observational study. The indications for pacemaker implantation were symptomatic third-degree atrioventricular block in one and sick sinus syndrome in eight patients. RESULTS PPI were implanted successfully in all 9 patients. Successful positioning of the ventricular leads at the right ventricular outflow tract (RVOT) septum with a "C" shaped stylet was achieved in 7 patients (77.8%). In the remaining two cases, the ventricular leads were placed in the right ventricular apex and the inferior free wall of the sub-tricuspid annulus. The atrial leads were placed at the lateral wall of the right atrium in all patients. Procedure time and fluoroscopy time were 85.3 ± 11.3 min and 4.5 ± 1.1 min respectively. During a mean follow-up of 4 years, no complications were observed and pacing parameters did not change significantly. CONCLUSION PPI through PLSVC may be technically feasible, safe, and effective. Double active fixation leads may be standard for patients with PLSVC and most of the ventricular leads could be placed at the RVOT septum.

Background Positioning a permanent pacing wire in patients with persistent left superior vena cava (PLSVC) to right ventricle often comes as on-table surprise. It is technically demanding and therefore most of operators prefer left-sided approach. We assessed technical challenges during pacemaker implantation, and their short- and long-term outcomes among patients with isolated PLSVC from a right-sided approach. Methods Thirty-one consecutive patients with isolated PLSVC and 93 patients with right superior vena cava (RSVC) were enrolled with syncope with sinus node dysfunction (SND) and atrioventricular (AV) block. Study was designed on the basis of nested case-control method, and therefore 1:3 proportions was the enrolment criteria to detect any difference as statistically significant as incidence of isolated PLSVC is low. Results Mean age of patients was 64.8 ± 10.5 years. SND was the most common indication (n = 55; 44%) followed by AV block (n = 47; 37%). Nineteen (20%) patients received tined pacing lead, while 105 (85%) had screwing lead. There was no significant difference in mean procedural time (25 ± 11 min vs. 23 ± 12 min; P = 0.24), mean fluoroscopic time (3.1 ± 2.2 min vs. 2.7 ± 2.1 min; P = 0.54), pacing parameters for atrial and ventricular leads, dislodgement rate (3.2% vs. 4.8%; P = 0.32) and follow-up duration (6.9 ± 1.3 years vs. 7.2 ± 1.1 years; P = 0.18) between two groups. Compared to patients with RSVC, those with PLSVC had alpha loop configuration for ventricular lead which was statistically significant (31 vs. 00; P = 0.002). Conclusions Patients with PLSVC had alpha loop configuration for ventricular lead because of circuitous course via left mediastinum. Although pacemaker implantation through coronary sinus via isolated PLSVC from right sided-approach is technically challenging, it obtains good long-term results but needs frequent follow-up during the initial period.

A rare variation of the hemiazygos vein draining into the persistent left superior vena cava. Anat Sci Int 2019; 94:269-273. [PMID: 30778907 DOI: 10.1007/s12565-019-00477-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2018] [Accepted: 01/30/2019] [Indexed: 10/27/2022]
Abstract
During an educational dissection of a 72-year-old Chinese male cadaver, the hemiazygos vein (HAV) coursing the left side that drains into the persistent left superior vena cava was observed. The HAV was formed at the junction of the 9th to 11th right posterior intercostal veins, right subcostal vein, 5th to 11th left posterior intercostal veins, and left subcostal vein; it then ascended posteriorly to the thoracic aorta. After collecting the accessory hemiazygos vein, it crossed over the aorta and the pedicle of the left lung via the hemiazygos arch, then converged with a communicative branch (vein of Marshall) that emerged from the left brachiocephalic vein to form the persistent left superior vena cava and entered the pericardium at the level of the sixth thoracic vertebra. Upon opening the pericardium of our cadaver, the persistent left superior vena cava was found to drain directly into the significantly dilated coronary sinus at the level of the eighth thoracic vertebra. The azygos vein was formed by the union of the first to eighth right posterior intercostal veins and appeared to be finer and shorter than the HAV. The persistent left superior vena cava might be the result of incomplete degeneration of the left posterior cardinal vein. Knowledge of such variations could be of great value to surgeons placing peripherally inserted central catheters because incorrect placement of the azygos venous system can be detrimental to the patient. In addition, during heart surgery, awareness of such variations may prevent major complications, such as hemorrhage or damage to vascular structures, and possibly also provide new insights and perspectives to cardiovascular surgeries.

Abstract
Aberrant right subclavian artery is the most common aortic arch anomaly that frequently occurs in coexistence with other congenital cardiovascular anomalies. A 32-year-old male patient was hospitalized with ventricular septal defect, chronic heart failure NYHA class III, pulmonary arterial hypertension. Contrast-enhanced multislice computed tomography revealed membranous ventricular septal defect, persistent left superior vena cava, bicuspid aortic valve and aberrant right subclavian artery. Aberrant right subclavian artery was clinically silent and discovered accidentally. The patient underwent heart-lung transplantation due to pronounced, irreversible pulmonary hypertension. This article reports a rare coexistence of aberrant right subclavian artery with other congenital anomalies of the heart and great vessels in living men.

Abstract
Persistent left superior vena cava (PLSVC) is the most common anomalous thoracic venous drainage. A PLSVC usually drains into the right atrium through a dilated coronary sinus. It is rare that a PLSVC flows directly into the left atrium, and even rarer that it connects to the left upper pulmonary vein (LUPV). We report a case, wherein the LUPV connected to both the PLSVC and the left atrium.

Abstract
We report the case of an 84-year-old female with symptomatic bradycardia due to a complete atrioventricular block, who carried absent right and persistent left superior vena cava (SVC). Implantation of a pacing lead, particularly within the right ventricle (RV) in a patient with this venous anomaly is accompanied by technical difficulties. However, the apparatus consisting of a fixed-curve sheath (Model C315-S10, Medtronic, Inc., Minneapolis, MN, USA) and a lumenless fixed-screw pacing lead (Model 3830, Medtronic), allowed a rapid delivery into the RV without any complications. By rotating the Model C315-S10 sheath in the counterclockwise direction in the right atrium, its tip faced the tricuspid orifice, advanced across the tricuspid valve and confronted the RV lower septum near the apex. Then the RV-lead was fixed with acceptable pacing and sensing parameters. Utilizing a lumenless pacing lead and a preformed sheath to deliver it is a novel approach that could be helpful in pacemaker implantation in patients with absent right and persistent left SVC.

Abstract
BACKGROUND The electrophysiological features and roles of persistent left superior vena cava (PLSVC) in supraventricular tachycardia (SVT) are not known. OBJECTIVE The purpose of this study was to elucidate the electrophysiological features and roles of PLSVC in patients with SVT. METHODS We included 37 patients with PLSVC (mean age 43.5 ± 17.1 years; 35.1% men) and 510 patients without PLSVC (mean age 43.9 ± 18.8 years; 48.2% men) who underwent an electrophysiology study for SVT. The number of induced tachycardias, location of the slow pathway (SP) or accessory pathway (AP), and radiofrequency catheter ablation (RFCA) outcomes were compared between patients with and without PLSVC. During RFCA of the left AP, a coronary sinus (CS) catheter was placed into the left superior vena cava (left superior vena cava group) or the great cardiac vein (great cardiac vein group). The RFCA outcomes were compared between the groups. RESULTS In patients with PLSVC, 40 tachycardias were induced: atrioventricular nodal reentrant tachycardia (AVNRT) (n = 19), atrioventricular reentrant tachycardia (n = 17), and focal atrial tachycardia (n = 4). Among patients with AVNRT, an SP in the CS was significantly more frequent in patients with PLSVC than in those without PLSVC (47.4% vs 3.8%; P < .001). In patients with the left AP, the number of RFCA attempts and recurrence were lower in the great cardiac vein group than in the left superior vena cava group. CONCLUSION An SP in the CS is prevalent in patients with AVNRT and PLSVC. It is useful to place a CS catheter into the great cardiac vein in patients with a left AP and PLSVC.

Abstract
A 69-year-old woman with palpitations was referred to our hospital for a second session of atrial fibrillation (AF) catheter ablation. She had a history of AF ablation including pulmonary vein (PV) isolation and persistent left superior vena cava (PLSVC) isolation. Electrophysiologic studies showed the veno-atrial connections that had recovered. After PV isolation was performed, AF was induced by atrial premature contraction (APC) from the PLSVC, and AF storm occurred. During PLSVC isolation, AF was not induced by APC from the PLSVC. PLSVC isolation continued during sinus rhythm. The elimination of the PLSVC potential was difficult to confirm because of the far-field potential of the left ventricle. Then, we performed right ventricular pacing. The remaining PLSVC potential was identified. After that, the PLSVC isolation was successful during right ventricular pacing. Complications were not observed. The patient had no recurrence of AF thereafter.

Abstract
Background Atrial fibrillation (AF) usually originates from pulmonary veins (PVs) but can also be caused by pulmonary veins outside, such as the coronary sinus (CS), the superior vena cava (SVC), and the ligament of Marshall. Case presentation A 69-year-old male with a history of palpitations for 10 years was referred to our institute because of its recurrence for half a day. A dynamic electrocardiogram revealed sinus rhythm (SR) and paroxysmal AF. Echocardiography demonstrated normal cardiac structure, and physical examination results were unremarkable. However, computed tomography angiography (CTA) showed a persistent left superior vena cava (LSVC) but no indication of thrombosis in the left atria. A cryoablation catheter was inserted into the PV. After the PV was successfully isolated, AF was still observed. After cardioversion was synchronized, SR was detected, but AF occurred again in less than a minute. Finally, we observed ectopic atrial electrical activity originating from the LSVC and successfully ablated it. Conclusions An LSVC may be a substrate for initiating or perpetuating atrial arrhythmia. Cryoballoon ablation can help treat AF originating from the LSVC.
