[Progressive cardiac tamponade and right ventricular free wall perforation as complications after dual-chamber pacemaker implantation - a case report].

Unlabelled: In recent years the number of complications related to implantation of cardiac stimulating systems is increasing. Life-threatening myocardial perforation leading to cardiac tamponade is one of the rarest complications. In that case it is necessary to take the immediate lifesaving procedures.

Gigantic aneurysm of a venous bypass graft causing superior vena cava syndrome.

A case of a 66-year-old patient 13 years after coronary artery bypass grafting (CABG) admitted to hospital with typical ischemic chest pain and symptoms of superior vena cava syndrome (SVCS) is described. Non-invasive diagnostics confirmed acute coronary syndrome: non-ST-elevated myocardial infarction (ACS NSTEMI). Trans-thoracic echocardiography (TTE) revealed a gigantic tumor mass modeling the right atrium, causing chronic cardiac tamponade.
