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

ABSTRACT: 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.

Radiofrequency catheter ablation in a patient with dextrocardia, persistent left superior vena cava, and atrioventricular nodal reentrant tachycardia: A case report.

Project description:RationaleDextrocardia is a rare congenital heart disease, while the persistent left superior vena cava (PLSVC) is an uncommon congenital vascular malformation. It is extremely rare for a person to have dextrocardia and PLSVC. A case with a combination of dextrocardia, PLSVC, and atrioventricular nodal reentrant tachycardia has not been reported.Patient concernsA 51-year-old woman was admitted to the hospital with palpitations. The physical examination revealed a heart rate of patient increased significantly, and that apex beating was found in the right fifth intercostal space approximately 0.5 cm from the midclavicular line.DiagnosisWe used different techniques, including electrocardiography, esophagus heart electrophysiology, chest radiograph, and cardiac color Doppler echocardiography to reveal the presence of the combination of dextrocardia, PLSVC, and supraventricular tachycardia.InterventionsWe terminated tachycardia by esophageal pacing and cured patients with radiofrequency catheter ablation (RFCA).OutcomesThe complex structural anomalies presented great technical challenges for interventional treatments. After consulting the literature, thorough examination and understanding of the structural anatomy and anomalies of the vena cava and cardiac chambers, we successfully treated this patient by RFCA. After half a year of follow-up, the patient did not have palpitations, and no arrhythmia was seen on the electrocardiography.LessonsPhysicians need to be aware that the key to the success of RFCA, in this case, is to clarify the complexity of the morphological and anatomical structures of dextrocardia accompanying PLSVC and to consult and understand the experience of access vessels reported in relevant cases before the operation.

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

Project description: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.

Three‐dimensional mapping of junctional beats during atrioventricular nodal reentrant tachycardia cryoablation

Project description:Cryoablation of slow pathway doesn't usually cause junctional beats. If this occurs, the nearness to AV compact node is supposed. 3d electroanatomical mapping during this unusual finding may help to clarify the relationship between junctional beats (JBs) during cryomapping/cryoablation and Koch's triangle.

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.

Non-Iatrogenic Localized-Reentrant Figure of Eight Atrial Tachycardias in the Superior Vena Cava

Project description:Introduction The superior vena cava (SVC) is an important non-pulmonary venous foci of atrial fibrillation (AF) and is known as the arrhythmogenic site of scar-related atrial tachycardia (AT). Scar-related ATs may occur after catheter ablation and open heart surgery; however, idiopathic AT rarely occurs. Case Presentation. A 77-year-old male with terminal diabetic nephropathy complained of dialysis-induced hypotension due to AF and was admitted to our hospital for catheter ablation. Here, we report a case of non-iatrogenic localized-reentrant figure of eight AT in the SVC. Conclusion SVC has the arrhythmogenic potential for re-entrant tachycardia, and the development of mapping technology can reveal arrhythmogenic mechanisms.

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.
