Superior vena cava syndrome early after pacemaker implantation in a patient with lung carcinoma: A case report

Revista Portuguesa de Cardiologia, 2019
Superior vena cava (SVC) syndrome is typically dramatic. Although the diagnosis is usually easy, elucidation of the etiology is difficult. We present a patient who developed SVC syndrome early after transvenous pacemaker implantation and who was ...
