Echocardiography as a noninvasive Swan-Ganz catheter.

Diwan and co-investigators report in this issue of Circulation that the interval between onset of mitral E and annular early diastolic velocity (Ea) by tissue Doppler, TE Ea, can be used to estimate left ventricular (LV) filling pressure in patients with mitral valve disease.1 Garcia and colleagues were the first to report that the onset of Ea occurred 7.5 3.5 ms after peak mitral inflow veloci...

Entrapment of a Swan-Ganz catheter.

Failure to withdraw a catheter is related primarily to catheter entrapment or knotting. Placement of a Swan-Ganz catheter is associated with various complications, one of which is entrapment. Entrapment of a Swan-Ganz catheter in the heart, vena cava, or pulmonary artery is a very rare and serious complication that may lead to life-threatening complications if not treated appropriately. Most re...

Multiple knotting of a swan-ganz catheter.

Complications derived from pulmonary artery catheter placement are about 3%-17%,1 from the most frequent and mild (carotid puncture, extrasystoles, etc) to the most severe (pulmonary artery rupture, pulmonary infarction, ventricular fibrillation, atrioventricular block, etc), and rare ones, such as intravascular catheter knotting, located preferentially in the right atrium (RA) or right ventric...
