As the list of interventions performed with the aid of femoral catheterization grows, so does the number of patients at risk for developing post-procedure problems. Here's a primer on how to recognize and prevent complications like pseudoaneurysm, arteriovenous fistulas, and retroperitoneal hematoma.
We examined 10 patients with idiopathic left ventricular (LV) aneurysm with sustained ventricular tachycardia (VT) (Id-An group), and compared them with those in 16 age- and sex-matched patients who had postinfarction aneurysm and VT (MI-An group) to clarify detailed clinical and electrophysiologic characteristics of idiopathic LV aneurysm. The clinical and laboratory data and results of electrocardiography, electrophysiologic, and morphologic examinations in the two groups were compared. In the Id-An group, the LV aneurysms were located more often at the posterior and/or inferior wall, while in the MI-An group, they were more often located at the anterior and/or apical wall (P<0.001). The LV end-diastolic volume index was significantly smaller and the LV ejection fraction was significantly higher in the Id-An group (P<0.001). The size of the aneurysm and the area with abnormal electrograms in the Id-An group were significantly smaller than those in the MI-An group (P<0.005 and P<0.001, respectively). The inducibility of VT was high in both groups, and ventricular pacing during VT showed entrainment phenomenon in most of the patients. Thus, in both groups, the abnormal electrograms were closely associated with the wall motion abnormality, and reentry was suggested as the mechanism of VT. In the Id-An group, since the lesions were anatomically and electrophysiologically confined to the posterior and/or inferior wall, the global LV function was more well preserved compared with the MI-An group.
