Abstract
Persistent left superior vena cava (PLSVC) is an anatomic variant that is relatively uncommon in the general population. Lead extraction through PLSVC is extremely rare. Due to unusual anatomy, the procedure carries challenges that require special considerations and careful planning. The authors report a case of lead extraction through a PLSVC with occluded right superior vena cava and highlight the challenges and outcomes of the procedure.

Abstract
BACKGROUND Atrial fibrillation is the most common sustained cardiac arrhythmia in adults and it is associated with a high burden of mortality and morbidity worldwide. Catheter ablation is increasingly used to improve symptoms and prognosis in selected patients. Lower limb venous access with subsequent transseptal approach to the left atrium is the standard procedure for atrial fibrillation catheter ablation. CASE PRESENTATION We report an unusual case of complex venous anomaly with a left-sided inferior vena cava with hemiazygos continuation to a persistent left superior vena cava draining in an enlarged coronary sinus in a patient with persistent atrial fibrillation scheduled for transcatheter ablation. DISCUSSION Lower limb venous anomalies may limit a standard transseptal approach to the left atrium thus precluding an effective catheter ablation procedure for atrial fibrillation. Alternative interventions, such as unconventional percutaneous access, thoracoscopic approach and "ablate and pace" procedures, may be necessary in patients with symptomatic atrial fibrillation and complex venous anomalies.

Abstract
BACKGROUND The persistent left superior vena cava (PLSVC) is an infrequent vascular variant. PLSVC with absent right superior vena cava, also known as isolated PLSVC, is an exceptionally rare entity. In this case we present a patient with isolated PLSVC draining to coronary sinus, diagnosed incidentally during echocardiography. CASE PRESENTATION A 35-year-old man underwent a transthoracic echocardiography which showed an enormously dilated coronary sinus. Hand-agitated saline was injected via peripheral intravenous cannulas. The contrast appeared firstly in the coronary sinus before it opacified the right atrium. Since this was also visible by the right antecubital saline injection, it indicated an extremely rare case of PLSVC with the absence of right superior vena cava which was confirmed by cardiac magnetic resonance. CONCLUSIONS The finding of a distinctively dilated coronary sinus in echocardiography led us to further investigation using agitated saline that revealed an infrequent anomaly termed isolated PLSVC. The in-depth diagnosis of this vascular variant is crucial considering that it may lead to important clinical implications, such as difficulties with central venous access, especially in the current era of a rapid development of cardiac device therapies.

Abstract
To report the prevalence of coarctation of the aorta (CoA) in fetuses with single left superior vena cava (SL-SVC) and to evaluate changes in echocardiographic measurements. Additionally, to report the prevalence of associated malformations. Retrospective observational study of fetuses diagnosed with SL-SVC between 2012 and 2021 at a tertiary fetal cardiology unit. In fetuses without intracardiac abnormalities, Z-scores of the ventricles, great arteries, and Doppler flow patterns are reported. We identified 47 fetuses with SL-SVC of which 8/47 (17%) had abnormal intracardiac anatomy. One fetus was lost to follow-up. Of those with normal intracardiac anatomy and postnatal follow-up (38), karyotype abnormalities were confirmed in 2/38 (5%) and ECA in 8/38 (21%). 33/38 were live-born. None developed CoA postnatally. Paired analysis of Z-scores between early and late scans of 24 fetuses showed that diameters of the right heart structures and Doppler flows of tricuspid valve increased significantly during pregnancy, while the left heart structures and flow patterns did not change. The median risk of CoA did not change between the early and the late scan. We did not observe CoA in this cohort. A degree of ventricular asymmetry was present, but this was due to right heart dominance rather than hypoplasia of left heart structures. This likely reflects redistribution of blood and does not appear to confer increased risk of CoA. Predictive models of the postnatal development of CoA which set the dimensions of right and left heart structures in relation might not be applicable in this situation.

Abstract
Background Persistent left superior vena cava (PLSVC) with absent right superior vena cava, also termed 'isolated PLSVC', is extremely rare. Permanent pacemaker implantation in patients with isolated PLSVC is often difficult by the usual subclavian approach due to the unique anatomy. With the advent of delivery catheters in recent years, implantation using the same system has been reported. Case summary A 47-year-old woman with symptomatic sick sinus syndrome was admitted to our institution for permanent pacemaker implantation. Preprocedural cardiac multidetector computed tomography (MDCT) showed isolated PLSVC. We performed pacemaker implantation successfully via the left subclavian approach, using the C315 delivery catheter system. The leads were stable on chest radiography, and the sensing and capture thresholds were unchanged. After the procedure, we integrated the delivery catheter images with cardiac MDCT using Ziostation, and they were well matched with the fluoroscopic images. At the 1-month follow-up, the patient was free of heart failure symptoms and had decreased levels of N-terminal prohormone of brain natriuretic peptide. Discussion The C315 delivery catheter system was considered an option for permanent pacemaker implantation in patients with isolated PLSVC. When performing permanent pacemaker implantation in patients with unusual venous anatomy, integrating the delivery catheter images with cardiac MDCT allows for appropriate preoperative catheter selection.

Abstract
This study aims to define the associated anomalies with PLSVC, and to compare single PLSVC and bilateral superior vena cava in terms of accompanying anomalies and pregnancy outcomes. This was a retrospective study of the fetuses diagnosed with single and/or bilateral SVC at a tertiary fetal medicine center during 8 years. We detected 16 cases of single PLSVC and 84 cases of bilateral SVC. We found an association between the PLSVC and cardiac and extracardiac anomalies. Comparison between single PLSVC and BSVC cases revealed significant differences in the occurrence of heterotaxy and right isomerism. The study highlights the importance of prenatal diagnosis in PLSVC cases. Isolated PLSVC with situs solitus may be considered a benign finding, but larger studies are needed to understand the clinical implications of PLSVC in relation to chromosomal anomalies. Routine screening protocols should include three-vessel and trachea views to detect PLSVC.

Abstract
Intracavitary electrocardiogram (IC-ECG) guidance is widely used for peripherally inserted central catheter (PICC) placement. The P wave variation has rarely been reported in persistent left superior vena cava (PLSVC). Here, we report a PLSVC case of P wave variation in PICC placement guided by IC-ECG. In this case, the P wave variation of the PLSVC was quite different from that of the right superior vena cava (RSVC). The tip of the catheter was located at the lower segment of the left superior vena cava according to postoperative radiography examination. PICC functioned normally, and no complications occurred.

Abstract
In an adult patient, coronary artery fistula involving the circumflex artery (CX) connected to the coronary sinus caused aneurysm of the left main and CX associated with ectasia of the intermediate branch. The patient had posterolateral infarction with severe ischemic mitral regurgitation and moderate tricuspid regurgitation. A rare venous return anomaly was also present. The inferior vena cava, which was interrupted at the level of the liver, continued with the hemiazygos to drain into a persistent left superior vena cava, which in turn drained into the coronary sinus. Surgery included CX closure and mitral and tricuspid repair. The strategy had to be adapted to the anatomy. The fistula was dissected and snared for cardioplegia delivery, and venous return was achieved by cannulation of the superior vena cava and femoral vein. The procedure was uneventful, and 4 years later the patient is asymptomatic.

Abstract
BACKGROUND Persistent left superior vena cava (PLSVC), a relatively rare thoracic vascular malformation, can inconvenience perfusionists and operators when encountered during deep hypothermic circulatory arrest (DHCA).
CASE SUMMARY Herein, we describe the case of a patient with concurrent giant aortic arch aneurysm, aortic stenosis, and PLSVC. To treat these conditions, we performed right hemiarch and aortic valve replacements under DHCA. Notably, we applied “bilateral superior vena cava retrograde cerebral perfusion (RCP)” for cerebral protection, which significantly optimized the surgical procedure and reduced the risk of postoperative complications. The patient was discharged 14 d after surgery with no complications.
CONCLUSION Surgical intervention for PLSVC under DHCA can be performed using the bilateral superior vena cava RCP approach.

Abstract
INTRODUCTION AND IMPORTANCE Persistent left superior vena cava (PLSVC) is a rare vascular anomaly that affects systemic venous circulation. PLSVC typically is asymptomatic as the return of venous blood to the right atrium occurs through the coronary sinus. It is important to possess a comprehensive understanding of drainage as it can present challenges in catheter placement on the right side of the heart, aiming to prevent potential complications. CASE PRESENTATION A 59-year-old female patient presented at the medical service with abdominal distention. During the examination, the presence of ascites was observed. Subsequent studies revealed peritoneal carcinomatosis of unknown origin. The patient underwent staging laparoscopy with biopsy sampling. Consequently, the placement of a catheter for chemotherapy was performed. A portable chest X-ray was obtained revealing the catheter extending along the left subclavian vein and progressing through the left paramediastinal regionThe presence of persistent left superior vena cava was confirmed after reviewing prior studies. CLINICAL DISCUSSION The most common abnormality in the venous drainage system is PLSVC. Approximately 40 % of PLSVC cases have associated significant cardiovascular anomalies, with septal defects being the most common. Recognizing anomalies and anatomical variants with the involvement of a multidisciplinary team is critical to prevent vascular complications during endovascular procedures and to tailor techniques for patients in need of cardiac endovascular procedures or cardiac devices. CONCLUSION PLSVC is often asymptomatic and discovered incidentally, it is essential to have a comprehensive understanding of this anomaly and perform meticulous imaging workup to prevent potential complications.

Abstract
BACKGROUND Persistent left superior vena cava (PLSVC) is the most common venous system variant. The clinical characteristics and amniotic fluid cytogenetics of fetuses with PLSVC remain to be further explored. AIM To develop reliable prenatal diagnostic recommendations through integrated analysis of the clinical characteristics of fetuses with PLSVC. METHODS Cases of PLSVC diagnosed using prenatal ultrasonography between September 2019 and November 2022 were retrospectively studied. The clinical characteristics of the pregnant women, ultrasonic imaging information, gestational age at diagnosis, pregnancy outcomes, and amniocentesis results were summarized and analyzed using categorical statistics and the chi-square test or Fisher's exact test. RESULTS Of the 97 cases diagnosed by prenatal ultrasound, 49 (50.5%) had isolated PLSVC and 48 (49.5%) had other structural abnormalities. The differences in pregnancy outcomes and amniocentesis conditions between the two groups were statistically significant (P < 0.05). No significant differences were identified between the two groups in terms of advanced maternal age and gestational age (P > 0.05). According to the results of the classification statistics, the most common intracardiac abnormality was a ventricular septal defect and the most common extracardiac abnormality was a single umbilical artery. In the subgroup analysis, the concurrent combination of intra- and extracardiac structural abnormalities was a risk factor for adverse pregnancy outcomes (odds ratio > 1, P < 0.05). Additionally, all abnormal cytogenetic findings on amniocentesis were observed in the comorbidity group. One case was diagnosed with 21-trisomy and six cases was diagnosed with chromosome segment duplication. CONCLUSION Examination for other structural abnormalities is strongly recommended when PLSVC is diagnosed. Poorer pregnancy outcomes and increased amniocentesis were observed in PLSVC cases with other structural abnormalities. Amniotic fluid cytogenetics of fetuses is recommended for PLSVC with other structural abnormalities.

Abstract
BACKGROUND Persistent left superior vena cava (PLSVC) is the most common variant of systemic venous drainage. In the absence of the right superior vena cava (RSVC), implantation of a right ventricular pacing lead may be challenging. Therefore specific implantation techniques and experiences in PLSVC are worth reporting. CASE PRESENTATION We present a case report of a 90-year-old Caucasian female patient with PLSVC during single chamber pacemaker implantation due to the third-degree atrioventricular block. With common implantation techniques, we did not even reach the right ventricle. Therefore slittable CPS Direct ™ Universal sheath was employed to overcome the acute angle from PLSVC to tricuspid valve and ensure more fixation stability for longer 100-cm right ventricular lead placement. CONCLUSION This case demonstrates safe implantation of 100-cm long right ventricular bipolar active fixation pacing lead using common slittable CPS Direct ™ Universal sheath after failed attempts with "C" and "J" stylet shaped electrode. This sheath provides different angle towards tricuspid valve and more fixation stability in patient with PLSVC and absent connection to right atrium.

Abstract
Persistent left superior vena cava (PLSVC) is a rare congenital anomaly. PLSVC can be associated with clinically significant atrial septal defect (ASD) or ventricular septal defect (VSD). It is usually asymptomatic and accidentally detected during invasive procedures or imaging examinations. However, whether central venous access device (CVAD) can be placed and used in patients with PLSVC is controversial. A total of six patients were diagnosed with PLSVC and confirmed by chest CT among 3391 cancer patients who underwent CVAD placement via intracavitary electrocardiogram (IC-EKG) at the Venous Access Center (VAC) from May 2019 to December 2020. The CVADs (peripherally inserted central catheter in four patients and Ports in two patients) of these six patients were left in PLSVC. We analyzed changes in the P-wave in the IC-EKG during CVAD placement and the characteristics of the body surface electrocardiogram in these patients and discussed the catheter tip position in PLSVC. All six patients showed negative P-waves in lead II via IC-EKG from the beginning of catheterization: four patients showed negative P-waves and two showed biphasic P-waves in the body surface electrocardiogram (lead III) before catheterization. CVAD function was normal and no obvious complications were observed during the treatment of these patients. The total retention time of CVADs was 1537 days. For patients with a negative P-wave in lead II via IC-EKG during catheterization, especially in those with a negative or biphasic P-wave in lead III of the body surface electrocardiogram, PLSVC should be considered. CVAD insertion in patients with type I PLSVC is safe under certain conditions, with the proper tip position in the middle to lower part of PLSVC.

Abstract
BACKGROUND Wolff-Parkinson-White syndrome is characterized by a short PR interval (delta-wave), long QRS complex, and the appearance of paroxysmal supraventricular tachycardia. Patients with Wolff-Parkinson-White syndrome usually have one accessory pathway, whereas cases with multiple accessory pathways are rare. Persistent left superior vena cava is a vascular anomaly in which the vein drains into the right atrium through the coronary sinus at the junction of the left internal jugular and subclavian veins due to abnormal development of the left cardinal vein. The simultaneous presence of multiple accessory pathways and persistent left superior vena cava has not been reported before. CASE PRESENTATION A 56-year-old Japanese man with a 5-year history of palpitations was referred for radiofrequency catheter ablation due to increased frequency of tachycardia episodes in the previous 2 months. Persistent left superior vena cava was confirmed by transthoracic echocardiography and computed tomography. An electrophysiological study revealed that the accessory pathways were located in the left lateral wall, anterolateral wall, and posteroseptal region. They were completely ablated with radiofrequency energy application. CONCLUSIONS We reported an extremely rare case of a patient with multiple accessory pathways and persistent left superior vena cava. Our case may suggest a potential embryological relationship between the multiple accessory pathways and persistent left superior vena cava.

Abstract
Tunneled central venous catheters and ports provide a long-term method of delivering nutrition, hydration, or medications in children. When these devices are no longer needed, it is best practice to remove them entirely. Complications associated with having long-term venous access devices or the process of device removal include site infections, venous thrombosis or occlusion, device fracture, and possible migration of fractured fragments. We present a case of catheter fragmentation that occurred in a pediatric patient during removal of a 3-year-old left chest port that had been placed into a left superior vena cava (SVC).

Abstract
Persistent left superior vena cava (LSVC) that drains into the left atrium (LA) via the left superior pulmonary vein (LSPV) is a rare systemic venous drainage anomaly. It can cause cyanosis and unexplained recurrent strokes. Undiagnosed, it can seriously disrupt the conduct of the cardiopulmonary bypass (CPB), causing sudden air lock and/or flooding of the operative field with venous blood. Its connection with the LSPV outside the pericardium makes its intraoperative diagnosis difficult. We report here the case of a 48-year-old man operated for mitral and aortic valve endocarditis, complicating a Laubry-Pezzi syndrome. The opening of the LA was followed immediately by the entrance of high volume of air bubbles into the superior vena cava cannula which resulted in sudden air lock of the venous outflow line. After multiple lowerings and cessations of pump flow, partial clamping of this cannula resulted in flooding of the LA with venous blood coming from the LSPV. The heart luxation did not allow us to find the LSVC in its usual intrapericardial location, between the LSPV and the left appendage. We had to widely open the left pleura to expose its completely extrapericardial path and its communication with the LSPV. The LSVC was temporally clamped during the remainder of the surgical procedure, then ligated at both ends. The patient underwent mitral valve repair, closure of the infundibular septal defect, aortic valve replacement and tricuspid annuloplasty. He was discharged 10 days later.

Abstract
The intraoperative diagnosis of a persistent left superior vena cava (LSVC) that drains into the left atrium (LA) via the left superior pulmonary vein may be difficult because of its extrapericardial pathway. We report here the case of a 48-year-old man, operated for a mitro-aortic endocarditis complicating a Laubry-Pezzi syndrome. The opening of the LA was followed immediately by a sudden air lock. It was only after opening of the left pleura that we were able to find and then ligate the LSVC. The patient underwent mitral valve repair, closure of the infundibular septal defect and aortic valve replacement.

Abstract
BACKGROUND Breast cancer poses a great threat to females worldwide. There are various therapies available to cure this common disease, such as surgery, chemotherapy, radiotherapy, and immunotherapy. Implantable venous access ports (IVAP, referred to as PORT) have been widely used for breast cancer chemotherapy. Venous malformations are possible conditions encountered during PORT implantation. Persistent left superior vena cava (PLSVC) is a common superior vena cava malformation. Most patients have normal right superior vena cava without affecting hemodynamics, so patients often have no obvious symptoms.
CASE SUMMARY We incidentally found that two patients had PLSVC while a PORT was implanted via the internal jugular vein. Due to chemotherapy for breast cancer, PORT was successfully implanted under the guidance of ultrasound into these 2 patients. Positive chest X-ray examination after the operation showed that the catheter ran beside the left mediastinum and the end was located in the seventh thoracic vertebra. The patients had no catheter-related complications and successfully completed the course of chemotherapy. Ultrasonography found that the ratio of PORT outer diameter to PLSVC inner diameter was less than 0.45, which was in line with the recommendations of relevant literature and operating guidelines. The purpose of this article is to introduce two rare cases and review the relevant literature.
CONCLUSION Correct assessment of PLSVC status and ultrasound-guided PORT placement generally does not affect breast cancer patients chemotherapy.
