A modified balloon crush approach improves side branch access and side branch stent apposition during crush stenting of coronary bifurcation lesions
Authors: Collins Nicholas , Dzavik Vladimir
Published: August 2006

Objectives: Despite the advent of drug eluting stents and newer interventional techniques designed to treat the main vessel and side branch in bifurcation stenoses, optimal treatment of the side branch remains problematic. We aimed to assess the feasibility of a modified balloon crush technique for percutaneous treatment of coronary bifurcation stenoses. Background: Use of the crush technique in bifurcation stenoses remains limited by access to the side branch after main vessel stent deployment, as well as limitations of side branch stent deployment. The modified balloon crush technique aims to improve side branch access and stent apposition. Methods: The modified balloon crush is similar to the previously described balloon crush technique. Following side branch stent deployment, a balloon positioned in the main vessel is deployed to crush the proximal side branch stent. A guide wire is then placed into the side branch with a subsequent high‐pressure balloon inflation at the side branch ostium. This opens the stent struts at the ostium of the side branch, facilitating future passage of the guide wire following main vessel stent deployment, prior to kissing balloon inflation. Results: We performed this modification of the crush technique safely in 10 patients. We were successful in obtaining side branch access in nine of ten patients following initial main vessel stent deployment. In the only failure, there was a 90° angle between the main vessel and side branch. Conclusions: The modified balloon crush technique can be safely performed, while optimizing side branch access and side branch stent apposition. © 2006 Wiley‐Liss, Inc.

Authors: Madsen Esben Hjorth , Villadsen Anton Boel , Frøbert Ole
Published: August 2006

Coronary artery aneurysm is an unusual finding at coronary arteriography. We present a case of acute myocardial infarction and a giant aneurysm of the left circumflex coronary artery (CX) in a 70‐year‐old male with hypertension. The culprit lesion was a thrombus occupying the aneurysm and the distal CX. By an unconventional manoeuvre the thrombus was aspirated via the 7 French guiding catheter. After stent implantation in the distal CX a thrombolysis in myocardial infarction 3 flow was achieved and still present at 2‐month follow‐up. The patient was prescribed aspirin and clopidogrel as a life‐long therapy. © 2006 Wiley‐Liss, Inc.

Published: August 2006

OBJECTIVE: We examined the efficacy of drug‐eluting stent (DES) implantation (Sirolimus or Paclitaxel) in patients with ischemic cardiomyopathy and severe left ventricular (LV) dysfunction and compared the outcome with a similar group of patients undergoing bare metal stent (BMS) implantation. BACKGROUND: Patients with severe LV dysfunction are a high risk group. DES may improve the long term outcomes compared with BMS. METHODS: One hundred and ninety one patients (23% women) with severe LV dysfunction (LV ejection fraction ≤35%) underwent coronary stent implantation between May 2002 and May 2005 and were available for follow‐up. One hundred and twenty eight patients received DES (Sirolimus in 72 and Paclitaxel in 54) and 63 patients had BMS. Patients with acute S‐T elevation myocardial infarction (STEMI) were excluded. The primary endpoint was cardiovascular mortality. A composite endpoint of major adverse cardiac events (MACE) including cardiovascular mortality, myocardial infarction (MI), and target vessel revascularization (TVR) was the secondary endpoint. RESULTS: Mean follow‐up was 420 ± 271 days. No differences were noted in age (69 ± 10 years vs. 70 ± 10 years, P = NS), number of vessel disease (2.3 ± 0.7 vs. 2.2 ± 0.8, P = NS), history of congestive heart failure (47% vs. 46%, P = NS), MI (60% vs. 61%, P = NS), or number of treated vessels (1.3 ± 0.5 vs. 1.3 ± 0.6, P = NS) for the DES and BMS group, respectively. Diabetes was more common among DES patients (45% vs. 25%, P = 0.01). The left ventricular ejection fraction (LVEF) was similar between the two groups (28% ± 6% vs. 26% ± 8%, P = NS for the DES and BMS, respectively). During the follow‐up, there were a total of 25 deaths of which two were cancer related (2 in DES group). There were 23 cardiac deaths, 8/126 (6%) which occurred in the DES group and 15/63 (24%) in the BMS group (P = 0.05 by log‐rank test). MACE rate was 10% for the DES group and 41% for the BMS group (P = 0.003). NYHA class improved in both groups (from 2.5 ± 0.8 to 1.7 ± 0.8 in DES and from 2 ± 0.8 to 1.4 ± 0.7 in the BMS, P = NS). CONCLUSION: Compared with bare‐metal stents, DES implantation reduces mortality and MACE in high risk patients with severe left ventricular dysfunction. © 2006 Wiley‐Liss, Inc.

Published: August 2006

We compared two routes for myocardial delivery of therapeutics, transendocardial (TE) delivery with an intramyocardial injection catheter, and retrograde coronary venous (RCV) delivery with a balloon occlusion catheter in the interventricular vein. Methods: TE and RCV injection of 15 μm, neutron‐activatable microspheres was compared in healthy pigs (Group I, n = 3), pigs with a 1‐week‐old myocardial infarction (MI; group II, n = 5), and pigs with a 2‐weeks‐old MI (group III, n = 4). The MI was induced by a 1‐hr balloon occlusion in the LAD. Both methods were compared in the same animal using different microspheres. The RCV catheter allowed for continuous measurement of distal pressure and 2.5 × 106 microspheres were injected in 10 ml at 300 mmHg above balloon occlusion pressure. The TE injections were targeted to the infarct zone and 2.5 × 106 microspheres were distributed over 10 injections of 200 μl. Results: The retention of microspheres decreased with increase in MI age, but was comparable between devices within the groups. RCV delivery resulted in (14.3 ± 0.9)% microsphere retention in Group I, (10.3 ± 0.2)% in Group II, and (6.4 ± 0.1)% in group III (P < 0.05 versus group I). Microsphere retention after TE was (15.1 ± 0.7)% in group I, (18.9 ± 0.6)% in group II, (4.1 ± 0.1)% in Group III (P < 0.05 versus groups I and II). The RCV catheter delivered primarily to midventricular, antero‐septal segments, whereas TE targeted apical areas predominantly. Conclusions: Delivery efficacy was comparable between devices in each group however RCV targeted midventricular areas whereas TE targeted apical areas. © 2006 Wiley‐Liss, Inc.

Published: August 2006

Background:

The experience with direct myocardial injection of adenovirus encoding angiogenic growth factor is limited to invasive surgical approach. Accordingly, we sought to evaluate, for the first time, in a randomized, double‐blind, placebo‐controlled, phase I pilot study the safety and feasibility of percutaneous catheter‐based intramyocardial delivery of a replication‐deficient adenovector encoding the 121‐amino‐acid isoform of vascular endothelial growth factor (AdVEGF121).

Methods:

Ten “no‐option” patients with severe coronary artery disease were randomized (2:1) to receive AdVEGF121 (4 × 1010 pu) or placebo as fifteen 100 μL, evenly distributed, endomyocardial injections using a nonflouroscopic, 3‐dimensional mapping and injection (NOGA) catheter‐based system.

Results:

Injection procedure was successfully completed in all cases and was associated with no major adverse events. AdVEGF121 was considered potentially associated with a single serious adverse event of transient moderate fever. Elevated postprocedure CK and CK‐MB fraction levels were recorded in two placebo‐treated and three AdVEGF121‐treated patients; all CK measured values were <1.5 times upper limit of normal. All adenoviral cultures (urine and throat swab) were negative 24‐hr after dosing, and no significant changes in serial plasma VEGF levels were noted over time. At 12 months follow‐up, no cancers, proliferative retinal changes, or significant abnormalities in hepatic, renal or hematological indices were observed.

Conclusions:

Percutaneous, catheter‐based AdVEGF121 intramyocardial injection is a practical, feasible, and potentially safe approach for intramyocardial gene transfer. A larger randomized, phase II efficacy study is warranted. © 2006 Wiley‐Liss, Inc.

Published: August 2006

Objectives: The purpose of this study was to evaluate the clinical and angiographic outcomes of the Symbiot ePTFE covered stent versus bare metal stents (BMS) for the treatment of saphenous vein graft (SVG) disease. Background: The Symbiot stent was developed to reduce periprocedural complications, by potentially preventing distal embolization, and to serve as a possible barrier to cell migration, thus reducing restenosis. Methods: Symbiot III is a prospective, randomized trial of 400 patients at 45 US sites, with 201 patients in the Symbiot group and 199 in the BMS group. Randomization was stratified based on the intended use of embolic protection devices and glycoprotein IIb/IIIa inhibitors. The primary endpoint was percent diameter stenosis (%DS) as measured by quantitative coronary angiography at 8 months. Secondary endpoints included MACE (cardiac death, MI, TVR). Results: The groups were well matched for all baseline clinical and lesion characteristics. At 8 months, %DS was comparable between groups (30.9% Symbiot, 31.9% BMS, P = 0.80). Although the rates of binary restenosis in the stented segment were similar (29.1% Symbiot, 21.9% BMS, P = 0.17), more patients in the Symbiot group had binary restenosis at the proximal edge (9.0% Symbiot, 1.8% BMS, P = 0.0211). There was no difference in the incidence of MACE between groups (30.6% Symbiot, 26.6% BMS, P = 0.43). Conclusions: This study failed to show an advantage for the Symbiot stent in the treatment of degenerated SVGs. This PTFE covered stent does not appear to act as a barrier to prevent restenosis. © 2006 Wiley‐Liss, Inc.

Authors: Maroo Anjli , Rasmussen Peter A. , Masaryk Thomas J. , Ellis Stephen G. , Lincoff A. Michael , Kapadia Samir
Published: August 2006

Pseudoaneurysms in the coronary circulation are an uncommon occurrence that can develop spontaneously in the setting of atherosclerosis or can develop after catheter‐based coronary interventions. The natural history, clinical outcome, and optimal therapy for pseudoaneurysms in the coronary circulation are not clearly established. Recent advances in the techniques and technologies used for endovascular treatment of intracranial aneurysms may be applicable to the management of coronary aneurysms and pseudoaneurysms. We present a case of spontaneous coronary pseudoaneurysm formation after paclitaxel drug‐eluting stent implantation and a case of pseudoaneurysm formation in a saphenous vein graft that were both successfully treated with stent‐assisted detachable coil embolization. © 2006 Wiley‐Liss, Inc.

Authors: Pancholy Samir B. , Coppola John , Patel Tejas
Published: August 2006

Objectives: To study the effect of sublingual versus subcutaneous nitroglycerin on radial artery spasm caused by failed access attempts. Background: Radial artery spasm is the leading reason for failed radial access. We studied the efficacy of systemic versus local nitroglycerin in relieving radial artery spasm caused by needle entry resulting in failed cannulation. Methods: Fifty‐two consecutive patients were studied. All patients had failed attempt at radial artery cannulation, resulting in loss of radial pulse. Patients were divided in three groups, group I (n = 11), observed without additional treatment, group II (n = 20), administered 400 mcg of sublingual nitroglycerin, and group III (n = 21), administered 400 mcg of subcutaneous nitroglycerin at the site of the lost radial pulse. All patients were monitored for the return of radial pulse. Demographics, hemodynamics, and time to return of radial pulse as well as ability to successfully cannulate the radial artery were recorded. Results: Seventy‐two percent of group I patients, 90% of group II patients, and 100% of group III patients had re‐establishment of radial pulse. The time to return of radial pulse was significantly shorter for group III compared with that for group II (3 ± 1 min vs. 8 ± 1 min respectively, P < 0.001). Re‐establishment of radial pulse was faster in group II and group III compared with that in group I (18 ± 5 min, P < 0.001). Systolic blood pressure changes and headaches were less common in group III. Conclusion: Subcutaneous administration of nitroglycerin is superior in facilitating radial artery cannulation after initial failed attempt. © 2006 Wiley‐Liss, Inc.

Published: August 2006

Concurrent severe carotid and cardiac disease is a challenging situation where staged surgery is probably the most common strategy, although it is still controversial. We report in‐hospital and midterm outcome of 30 patients who received carotid stenting and synchronous cardiac surgery. All received carotid stenting under aspirin and regular unfractioned heparin (UFH) and were immediately transferred to the operating room for coronary and/or cardiac valve surgery. All patients received aspirin and clopidogrel once bleeding was ruled out, after surgery. In‐hospital complications were: three surgical related deaths, one TIA, and no patient suffered stroke or myocardial infarction. Hospital stay was 14 ± 11.8 days. Survivors were followed for 18.4 ± 14 months. There were two non‐related deaths, but no stroke nor cardiac or carotid reinterventions. In conclusion, this small series showed that synchronous carotid stenting and cardiac surgery was feasible with an acceptable complication rate in a high‐surgical‐risk population which could not undergo staged procedures. © 2006 Wiley‐Liss, Inc.
Vascular ultrasound imaging to study immediate postcatheterization vascular complications in children
Authors: Kulkarni Snehal , Naidu Renuka
Published: August 2006

Vascular occlusion is the major complication of percutaneous cardiac catheterization in children. This is a prospective study to evaluate post catheterization vascular complications in 120 consecutive children with the help of vascular ultrasound and Doppler imaging. Ultrasound imaging of both iliac and femoral veins and arteries was done one hour prior and 24 hours after cardiac catheterization. Patients with prior thrombus or occlusion of femoral/iliac vein or artery due to previous cardiac catheterization were excluded from the study. Age of the patients ranged from 22 days to 12 years with a mean of 56 months and weight ranged from 3 to 57 kgs with a mean of 14.3 kgs. Procedure time was less than 60 minutes in 74 patients (61.66%) and more than 60 minutes in 46 patients (38.33%). 4F sized arterial sheath was used in 108 patients. 5F or bigger sized arterial sheath was used in remaining 12 patients. Incidence of arterial occlusion was higher in patients weighing less than 10 kgs (16%) as compared with patients weighing more than l0 kgs (5.5%) {P = 0.031}. Arterial thrombosis was more in infants (16%) as compared with older children (7%) {P = 0.203} Prolonged procedure time or use of larger sized sheath did not have higher incidence of arterial occlusion. Venous thrombosis was found in 2 patients (1.66%) who had 5F venous sheath. One patient had arterio venous fistula. Our study shows vascular ultrasound imaging can provide anatomical details of femoral and iliac vessels and is a easier and accurate method of assessing postcatheterization vascular complications in children. © 2006 Wiley‐Liss, Inc.

Published: August 2006

As part of a study to achieve selective oligo(poly)bromination—ultimately perbromination—of the dodecahedral C20 skeleton, the extent and direction of the ionic bromination of dodecahedrene and 1,16‐dodecahedradiene were explored. Along sequences of Br+ additions/deprotonations and allylic rearrangements, up to ten hydrogen atoms were substituted (traces of C20HxBr10). Tetrabromododecahedrenes obtained under defined conditions in up to 50 % total yield with three and four allylic bromine substituents protecting the extremely bent CC bonds, proved highly unreactive even towards oxygen but reacted rapidly with CH2N2. Upon electron impact ionization (MS) of the newly secured oligo(poly)bromododecahedra(e)nes, sequential loss of the substituents ended generally in polyunsaturated dodecahedranes (in the extreme C20H4, “tetrahydro‐C20 fullerenes”). Only subsequently did skeletal fragmentations occur. From X‐ray crystal‐structure analyses, more information was obtained on the structural response of the dodecahedral skeleton to the strain induced by the voluminous substituents. As Appendix, the forcing radical bromination of 1,6‐dibromododecahedrane and exploratory cis‐β‐HBr/cis‐β‐Br2 eliminations in bromododecahedranes with [Fe2(CO)9], P2F/[FeCp2] and [Fe(tmeda)Cp*Cl] (in situ protection) are presented.

Structural and functional growth in self‐reproducing cellular automata
Authors: Bilotta Eleonora , Pantano Pietro
Published: August 2006

In this article, we analyze the dynamics of change in two‐dimensional self‐reproducers, identifying the processes that drive their evolution. We show that changes in self‐reproducers structure and behavior depend on their genetic memory. This consists of distinct yet interlinked components determining their form and function. In some cases these components degrade gracefully, changing only slightly; in others the changes destroy the original structure and function of the self‐reproducer. We sketch these processes at the genotype and the phenotype level—showing that they follow distinct trajectories within mutation space and quantifying the degree of change produced by different trajectories. We show that changes in structure and behavior depend on the interplay between the genotype and the phenotype. This determines universal structures, from which it is possible to construct a great number of self‐reproducing systems, as we observe in biology. Creative processes of change produce divergent and/or convergent methods for the generation of self‐reproducers. Divergence involves the creation of completely new information convergence involves local change and specialization of the structures concerned. © 2006 Wiley Periodicals, Inc.

From plasmacytoid to dendritic cell: Morphological and functional switches during plasmacytoid pre‐dendritic cell differentiation
Authors: Soumelis V. , Liu Y‐J.
Published: August 2006

Plasmacytoid dendritic cell precursors (pDC/IPC) are the major producers of type I interferon and have the unique ability to link innate and adaptive immunity. After producing large amounts of type I IFN in response to microbial stimulation, they can differentiate into DC capable of stimulating naive T cells and modulate the adaptive immune response. In this review, we focus on the transition between these two highly specialized cell types, which is accompanied by major morphological, structural and functional changes, many of which remain to be fully characterized. We propose that the plasmacytoid and dendritic morphologies correspond to distinct differentiation states and effector functions.
