Implantation of a cardiac resynchronization therapy defibrillator through a persistent left superior vena cava.

چکیده
A persistência da veia cava superior esquerda é incomum, estando presente em 0,3-2% da população em geral, com variação anatómica significativa. Reportamos um caso de um homem de 64 anos do sexo masculino com cardiomiopatia dilatada idiopática, internado eletivamente para implantação de um cardioversor-desfibrilhador. Obteve-se acesso venoso pela veia cefálica esquerda, tendo-se verificado que o eletrocateter progredia à esquerda da coluna vertebral. Injetou-se contraste, tendo-se constatado a existência de uma veia cava superior esquerda persistente, que drenava para a aurícula direita, em estreita proximidade com o ostium do seio coronário. Quando confrontados com esta anomalia congénita, muitos operadores optam por usar desde o início do procedimento técnicas especiais para a implantação, especialmente para dispositivos biventriculares. Alguns utilizam uma abordagem direita para facilitar a manipulação dos cateteres, enquanto outros usam abordagens híbridas (direita e esquerda no mesmo procedimento), e alguns implantam o eletrocateter ventricular direito no ventrículo esquerdo. No entanto, estas técnicas podem tornar-se bastante complexas, com risco acrescido de infeção e lesão vascular, especialmente perante uma abordagem bilateral. Assim, dado que vários autores, e a

CRT-D Implantation Through a Persistent Left Superior Vena Cava
A persistent left superior vena cava (PLSVC) was present in a 74 year-old man with dilated cardiomyopathy undergoing implantation of a cardiac resynchronization therapy device with defibrillator (CRT-D). A dual-coil active-fixation defibrillator lead was positioned in the right ventricular apex, followed by a SonR active fixation lead in the right atrial free wall. The coronary sinus lead was a...
متن کاملRight-sided implantation of a cardiac resynchronization therapy defibrillator in a case of persistent left superior vena cava.
Persistent left superior vena cava represents a congenital venous anomaly that poses a particular obstacle to the implantation of cardiac rhythm management devices. In the present report we briefly describe the rightsided implantation of a biventricular defibrillator in a patient with persistent left superior vena cava. We also briefly discuss the technically challenging procedures applied in s...
متن کاملImplantation of a cardiac resynchronization therapy-defibrillator device in a patient with persistent left superior vena cava.
Presence of a persistent left superior vena cava (PLSVC) is generally clinically asymptomatic and discovered incidentally during central venous catheterization. However, PLSVC may cause technical difficulties during cardiac device implantation. An 82-year-old man with heart failure symptoms and an ejection fraction (EF) of 20% was scheduled for resynchronization therapy-defibrillator device (CR...
متن کاملImplantation of a Resynchronization Implantable Cardioverter Defibrillator in a Patient with Persistent Left Superior Vena Cava
Implantation of resynchronization implantable cardioverter defibrillator was performed in a patient with persistent left superior vena cava. A dual coil defibrillation lead was inserted in the right ventricle apex via a small innominate vein. Left ventricular and atrial leads were implanted through persistent left superior vena cava. Left ventricular lead was easily implanted into the postero l...
متن کاملCardiac Resynchronization Therapy in a Patient with Persistent Left Superior Vena Cava Draining into the Coronary Sinus and Absent Innominate Vein: A Case Report and Review of Literature
INTRODUCTION Persistent left superior vena cava (PLSVC) is a rare congenital anomaly of the superior venous system that may be discovered at the time of cardiac implantable electronic device (CIED) implantation. METHODS AND RESULTS We present a subject who needed cardiac resynchronization therapy (CRT)-CIED implantation and was discovered to have PLSVC with absent innominate vein during the i...
متن کاملResynchronization in the left superior vena cava
Background: Persistent Left Superior Vena Cava (PLSVC) is a rare congenital anomaly which is typically asymptomatic and discovered incidentally during device implantation. Methods: In this case, we present challenges and techniques of Cardiac Resynchronization Therapy (CRT) in a patient with PLSVC. Results: After evaluating the exact anatomy of PLSVC and Coronary Sinus (CS), we chose the approp...
