Isolated persistent left-sided superior vena cava, giant coronary sinus, atrial tachycardia and heart failure in a child.

ABSTRACT: Persistence of a left-sided superior vena cava (PLSVC) with absent right superior vena cava (isolated PLSVC) is a very rare venous malformation and commonly associated with congenital heart disease or alterations of the cardiac situs. We describe an unusual case of a young boy presenting with persistent atrial tachycardia and congestive heart failure. He was detected to have unexplained grossly dilated right atrium, right ventricle with systolic dysfunction and a giant coronary sinus (CS). The dilated CS closely mimicked a pseudo cor-triatriatum on echocardiography. Contrast echocardiography from both arms revealed opacification of the CS before the right atrium. Bilateral upper limb venography confirmed the presence of absent right SVC and isolated persistent left SVC draining into the giant coronary sinus.

Ablation of atrioventricular-nodal-reentrant- tachycardia in a patient with left-sided superior vena cava and dilated coronary sinus.

Project description:Atrioventricular (AV)-nodal-reentrant-tachycardia is a rare association in a patient with persistent left-sided superior vena cava and dilated coronary sinus. There are a few inherent difficulties in ablation in this condition, viz., difficulty in localization of good site for ablation and difficulty in stabilization of the ablation catheter at the designated site, making it difficult to produce transmural lesions and increasing risk of producing AV block. We hereby present a case highlighting the difficulties and possible solutions for them.

Endovascular retrieval of foreign body in persistent left-sided superior vena cava.

Project description:Endovascular retrieval of a foreign body is becoming an increasingly common procedure in the management of complications resulting from more frequent endovascular procedures. Many procedures are performed on a regular basis in assessment of vascular anatomy, endovascular-guided therapy, and catheter placement. This case report depicts a complication of a chemoport placement resulting in a foreign body. Evaluation of the foreign body raised attention to aberrant anatomy, a persistent left-sided superior vena cava. We further discuss briefly the embryology behind a persistent left-sided superior vena cava, technical errors leading to the foreign body, and assessing the nature of the foreign body through different imaging modalities. This is followed by the subsequent endovascular retrieval by Interventional Radiology and a literature review and individual case assessment of endovascular foreign body retrieval. We discuss considerations for practice based upon our literature review.

Unroofed coronary sinus and persistent left superior vena cava: A case report.

Project description:The unroofed coronary sinus is a spectrum of cardiac anomalies in which part or all of the common wall between the coronary sinus and the left atrium is absent. Most cases are associated with anomalous systemic venous return, such as persistent left superior vena cava.The diagnosis of this lesion is important to the prognosis of the patient, but it is often difficult because of nonspecific clinical features.Here we report a case of a complete unroofed coronary sinus and persistent left superior vena cava discovered during a computed tomographic investigation for pulmonary hypertension.

Persistent Left Superior Vena Cava: A Rare Association.

Project description:Persistent left superior vena cava (PLSVC) is the most frequent abnormality in the general population with the frequency of 0.1% to 0.5%. It results from the failure of the involution of the left anterior cardinal vein. Right and Left SVC can coexist together in 80% to 90% of cases. Association of PLSVC with ano rectal malformation (ARM) is very rarely reported. Hence, here is a report of a unique case of PLSVC in a female neonate with ARM.

Pacemaker Placement in Persistent Left Superior Vena Cava.

Project description:Persistent left superior vena cava (PLSVC) is a rare disorder which is asymptomatic and hence is usually discovered while performing interventions through the left subclavian vein. We present a case of a 78-year-old male who was undergoing elective placement of a permanent pacemaker for tachycardia - bradycardia syndrome with post-conversion pauses of up to nine seconds. After achieving access through the left subclavian vein the wire kept on going on the left side of the chest instead of crossing the midline to the right side. The wire was removed and contrast venography was done, PLSVC with dilated coronary sinus emptying into the right atrium was confirmed. There was some difficulty in passing the lead to the right ventricle even with the acute curve in the stylet. The sheath size was increased and a longer deflectable sheath was used and with the tip of the lead anteriorly the right ventricle was cannulated and the lead was affixed. There were good sensing and pacing parameters. Post procedure chest x-ray was done and the patient was discharged without any complications.

Persistent Left Superior Vena Cava: Implications of Surgical Management.

Project description:Persistent left superior vena cava is the most common congenital anomaly of thoracic venous return, which results when the left anterior cardinal vein fails to regress. A 41-year-old African American male with a history of an unspecified childhood cardiac murmur presented to the emergency department with congestive heart failure exacerbation revealing an incidental finding of a persistent left superior vena cava. Ultimately, he required implantable cardioverter defibrillator placement and cardiac transplantation assessment. In the setting of advanced device placement or cardiac transplantation, a persistent left superior vena cava warrants several important clinical considerations at a center capable of addressing the possibility of a right-sided approach and transplantation irregularities.

Persistent left superior vena cava draining into the left atrium.

Project description:A 40-year-old man was admitted with necrotising fasciitis of the right thigh. Further workup to evaluate for an infectious source revealed an incidental finding of persistent left superior vena cava via transesophageal echocardiography. This finding was confirmed by cardiac MRI. During his hospitalisation, he also developed altered mental status which was found to be secondary to systemic emboli by a head MRI. The primary source of infection was likely his dental abscesses. He underwent intravenous antibiotic therapy for a total of 6 weeks and was then referred to a specialised vascular centre for further management of his congenital anomaly.

A case report: upgrade to cardiac resynchronization therapy with a blocked persistent left-sided superior vena cava.

Project description:BackgroundPacemaker-induced cardiomyopathy (PICM) can occur in up to 9% of patients having a pacemaker. Pacemaker-induced cardiomyopathy can be treated by upgrade to a biventricular pacemaker with a left ventricular (LV) lead implantation. The procedure can be technically challenging in patients with persistent left-sided superior vena cava (PLSVC).Case summaryWe report the case of a 72-year-old gentleman with a PLSVC, who had a dual-chamber pacemaker implanted 15 years ago for complete heart block. After 12 years of good health, the gentleman developed breathlessness due to PICM. At upgrade to biventricular pacemaker, his coronary sinus was found to be occluded and a collateral branch was used to successfully position an LV lead. Marked clinical improvement was seen before representation with syncope after 2 years due to simultaneous failure of both LV and right ventricular leads. Subsequently, a right-sided de novo biventricular pacemaker was implanted. In this instance, the PLSVC was beneficial because it isolated the existing leads from the new implant, thereby reducing the risk of SVC obstruction.DiscussionAlthough implantation of pacemaker leads through a PLSVC constitutes a challenging procedure due to manoeuvring difficulties of the pacing leads into the cardiac chambers, in this particular case, the presence of PLSVC was beneficial because it meant that no leads were present in the true SVC, reducing the risk of occlusion and avoiding the need for lead extraction.
