Right Atrial, Right Ventricular, Superior Vena Cava Dissection Caused by Swan-Ganz Catheter Placement
J INVASIVE CARDIOL 2019;31(5):E95.
Key words: echocardiogram, dissection
A 62-year-old male with an abnormal stress test underwent stent placement of the left anterior descending coronary artery. Soon after, this was complicated by stent thrombosis leading to cardiogenic shock that was refractory to pressors, requiring intra-aortic balloon placement. The patient was eventually weaned off pressors and ventilatory support, but developed septic shock secondary to hospital-acquired pneumonia, and shortly thereafter developed cardiogenic shock. A Swan-Ganz catheter was then placed with the aide of an Arrow Spring-Wire guide (Teleflex), marked 0.035˝ diameter x 17-3/4˝ with an Arrow Advancer (Teleflex). The patient remained hemodynamically stable throughout the procedure. Transesophageal echocardiography was then performed after placement to rule out any cardiogenic abnormalities contributing to the presentation. Results demonstrated a right atrial dissection with extension into the superior vena cava and right ventricle not seen on previous echocardiographic findings (Figures 1 and 2). No intervention was performed as the patient’s hemodynamic status improved. We propose that during Swan-Ganz catheter placement, the guidewire sheared the intimal lining of the superior vena cava and endocardium.
