Published: July 2008

AbstractObjectives: The main objective of this study is to describe a new technique for rapid ventricular pacing to maintain balloon stability during balloon aortic valvuloplasty (BAV) without using transvenous temporary pacemaker electrode. Background: The safety and efficacy of rapid right ventricular pacing to facilitate balloon stability during BAV has been previously reported. However, it necessitates an additional femoral venous access, an additional sheath, and a temporary pacemaker electrode. Methods: This was a prospective pilot study. Rapid ventricular pacing was performed through back‐up guidewires inserted into the left ventricle for balloon advancement and by an adhesive patch placed on the back of the patient. The technique was performed during BAV procedure in all of 15 consecutive children diagnosed as congenital aortic stenosis. Pacing was performed at a rate decreasing systolic aortic pressure to the point of 40–50% of baseline. Results: The technique was successful in all patients. Effective capture, stable pacing, and balloon stability were achieved in all children using very low outputs. No sustained arrhythmias or other procedure‐related complications occurred. Mean aortic valve gradient decreased from 68.5 ± 20.4 mm Hg to 20.4 ± 10.2 mm Hg. Degree of aortic regurgitation progressed from grade 0 to 1 in three patients and remained unchanged in 12 patients. Conclusions: This study demonstrated that back‐up guidewires can be used effectively and safely for pacing during BAV procedures. This technique omits probable complications related to a second vascular access and may shorten the procedure time and decreases costs by eliminating the use of an additional sheath and a temporary pacemaker electrode. © 2008 Wiley‐Liss, Inc.

Published: July 2008

AbstractObjectives: Our purpose was to determine the feasibility and safety of transcatheter coil occlusion of a perimembranous VSD. Background: Transcatheter coil occlusion of a perimembranous ventricular septal defect (VSD) may be a useful treatment; however, there are few reports on its technical aspects and outcome. Methods: We attempted coil closure of a perimembranous VSD in 41 patients. We approached the VSD via the right ventricle (RV) in 16, via the left ventricle (LV) in 16, simultaneously deployed two coils from the RV (RV/RV) in three, and simultaneously deployed two, three, or four coils from the RV and LV (RV/LV) in six. Coils (0.038″ flipper, 0.052″ Gianturco, or 0.035″ platinum coil) were placed into the defect through the delivery catheter until any flow through the VSD disappeared or became trivial on angiography. Results: We achieved 100% complete closure in all patients in whom coils were deployed, although some patients required a second session. A flipper coil used alone was insufficient to completely occlude VSDs larger than 2.5 mm. Conclusions: Transcatheter coil occlusion of a VSD can be performed reliably and safely by selecting appropriate embolic coils. Small defects (<2.5 mm) can be closed with a flipper coil, but defects ≥2.5 mm require a 0.052″ coil. © 2008 Wiley‐Liss, Inc.
A modified “Preclosure” technique after percutaneous aortic valve replacement
Authors: Kahlert Philipp , Eggebrecht Holger , Erbel Raimund , Sack Stefan 
Published: July 2008

AbstractObjectives: To evaluate the feasibility, safety and efficacy of suture‐mediated closure devices using a modified “preclosure” technique for access site management after percutaneous aortic valve replacement (PAVR). Background: PAVR using a retrograde transfemoral approach has recently evolved to an endovascular alternative to open surgery in high‐risk patients. However, large‐bore femoral artery access is required, commonly demanding surgical closure and general anesthesia. A truly percutaneous intervention would be desirable to reduce procedural complexity and diminish the need of vascular surgery and general anaesthesia. Methods: After direct puncture of the common femoral artery, three conventional suture‐mediated closure devices (6F Perclose) were deployed. The preloaded sutures were tied at the end of the procedure. If no immediate hemostasis was achieved, an additional device was deployed thereafter. Results: PAVR with percutaneous access site closure was attempted in 15 consecutive patients and could successfully be achieved in all patients allowing conscious sedation in all but three cases. Following complications occurred: one retroperitoneal bleeding caused by removal of the valve delivery sheath requiring surgical repair, as well as two cases of femoral and iliac artery dissection caused by delivery sheath introduction and treated by stenting and vascular surgery, respectively. Vascular surgery became only necessary due to total vessel occlusion after suture closure and remains the only closure‐related complication. However, treatment led to recovery in all patients. Conclusions: The modified “preclosure” technique is a feasible and safe method for hemostasis after PAVR improving procedural management and diminishing the need for general anesthesia. © 2008 Wiley‐Liss, Inc.
A prospective, double‐blind, randomized, controlled trial on the efficacy and cardiorenal safety of iodixanol vs. iopromide in patients with chronic kidney disease undergoing coronary angiography with or without percutaneous coronary intervention

Published: July 2008

AbstractObjectives:This study was undertaken to compare the renal safety as well as cardiovascular (CV) effects and diagnostic image quality of iso‐osmolar iodixanol vs. low‐osmolar iopromide in patients with chronic kidney disease (CKD) undergoing coronary interventions.Background:With the growing number of contrast‐enhanced procedures being performed for coronary artery disease management, the safety and efficacy of iodinated contrast media (CM) have come under increased scrutiny.Methods:Patients with CKD (CrCl ≤60 mL/min) were randomized to iodixanol (n = 106) or iopromide (n = 102). The primary endpoint was incidence of contrast‐induced nephropathy (CIN), defined as an increase in serum creatinine (SCr) ≥25% or 0.5 mg/dL within 72 hr of CM administration. Secondary endpoints were mean SCr increase, a composite of CV events in‐hospital and 30 days postdischarge, and diagnostic image quality.Results:CIN incidence was significantly lower with iodixanol than iopromide (5.7% vs. 16.7%; P = 0.011). Baseline SCr (OR 2.21, 95% CI: 1.25–3.47; P = 0.031), iopromide use (OR 2.56, 95% CI: 1.18–5.76; P = 0.024), and CM volume (OR 2.01, 95% CI: 1.01–3.21; P = 0.038) were identified as independent risk factors for CIN. Cardiovascular events were reduced with iodixanol (1.9% vs. 8.8%; P = 0.025); diagnostic image quality was similar for both CM (P = 0.353).Conclusions:Consistent with several previous trials comparing iso‐osmolar iodixanol and low‐osmolar comparator CM, iodixanol was associated with a lower incidence of CIN and fewer CV events than iopromide. © 2008 Wiley‐Liss, Inc.

AbstractObjectives:To investigate the feasibility and safety of manual thrombus aspiration in patients undergoing percutaneous coronary intervention (PCI) for non‐ST‐elevation myocardial infarction (NSTEMI).Background:Myocardial necrosis in patients with acute coronary syndromes may be a sign of microvascular obstruction, owing to spontaneous or PCI‐induced embolization of atherothrombotic material. Manual thrombus aspiration results in improved myocardial reperfusion in patients undergoing PCI for ST‐elevation myocardial infarction. Currently, no published data on thrombus aspiration in patients with NSTEMI are available.Methods:As part of a prospective cohort study, 70 patients undergoing PCI for NSTEMI were treated with thrombus aspiration (Export Aspiration Catheter, Medtronic, Minneapolis, MN). Histopathological analysis was performed on aspirated material.Results:Thrombus aspiration was effective in 58 patients (83%) and resulted in a marked reduction of TIMI‐thrombus score 4/5 (40% pre‐ versus 7% postthrombus aspiration) and increase of the rate of TIMI‐flow 3 (36% pre‐ versus 66% postthrombus aspiration). The incidence of myocardial blush grade 2 and 3 were 39 and 45%, respectively. Distal embolization was visible in three patients (4%) on the final angiogram.Conclusion:This study demonstrates that thrombus aspiration in most NSTEMI patients is feasible and safe and is associated with a high rate of retrieval of thrombotic material. © 2008 Wiley‐Liss, Inc.
