  • Adverse Events Associated with the Use of Guide Extension Catheters during Percutaneous Coronary Intervention: Reports from the Manufacturer and User Facility Device Experience (MAUDE) database.

    Co-Authors: Yuefeng Chen, Arhum A. Shah, Nauman Khalid, Anees Musallam, Jaffar M. Khan, Micaela Iantorno, Deepakraj Gajanana, Toby Rogers, Evan Shlofmitz, Hayder Hashim
    Abstract:

    Abstract Background/purpose We aimed to assess the reported complications and event modes for the GuideLiner and Guidezilla extension catheters. Methods/materials The US Food and Drug Administration (FDA) Manufacturer and User Facility Device Experience (MAUDE) database was queried for reported events. Results Of the 65 cases with reported GuideLiner-related issues, 15 (23%) involved the inability to pass equipment through or damage to percutaneous Coronary intervention (PCI) devices in the GuideLiner catheter, 38 (58%) involved GuideLiner catheter fracture, 9 (14%) involved Coronary Artery dissection, 2 (3%) involved Coronary Artery Perforation, and 1 (1.5%) involved thrombus formation in the catheter. Of the 408 cases with reported Guidezilla-related issues, 53 (13%) involved inability to pass or damaged PCI devices into the Guidezilla catheter, 117 (29%) involved inability to advance the Guidezilla catheter to the target lesion, 59 (14%) involved kinked Guidezilla catheter, mostly because of partial or complete catheter fracture upon further investigation, 164 (40%) involved a broken Guidezilla catheter, 10 (2.5%) involved Coronary Artery dissection, 2 (0.5%) involved Coronary Artery Perforation, 1 (0.2%)involved aortic dissection, 1 (0.2%) involved thrombosis formation, and 1 (0.2%) involved no-reflow phenomenon. Conclusions Findings from the MAUDE database highlight the complications and modes of events associated with the use of GuideLiner and Guidezilla extension catheters. Summary To assess the reported complications and event modes for the GuideLiner and Guidezilla extension catheters, the US Food and Drug Administration (FDA) Manufacturer and User Facility Device Experience (MAUDE) database was queried. There were more reports on Guidezilla-related events during the search period. The events for both extension catheters mainly involved the inability to pass equipment through or damage to percutaneous Coronary intervention (PCI) devices in the extension catheter, extension catheter fracture, Coronary Artery dissection and Perforation and, occasionally, the death of the patients.

  • Coronary Artery Perforation at the level of two overlapping bioresorbable vascular scaffolds the importance of vessel sizing and scaffold thickness
    Catheterization and Cardiovascular Interventions, 2015
    Co-Authors: Maxime Pichette, Philippe Genereux, Florent Chevalier
    Abstract:

    Everolimus-eluting bioresorbable vascular scaffolds (BVS) have emerged as an alternative to conventional metallic stents and have demonstrated favorable outcomes in simple Coronary lesions. As the use of BVS increases and extends to more complex lesion subsets, intraprocedural complications are expected to occur. We describe for the first time the occurrence of a free Coronary Perforation localized at the exact point of overlap of two BVS. This case illustrates the importance of appropriate vessel sizing, especially when BVS overlapping is performed in a small vessel, and potential advantages of scaffold juxtaposition compared to overlapping when implanting BVS in series. © 2015 Wiley Periodicals, Inc.

  • dual catheter technique for the treatment of severe Coronary Artery Perforations

    Abstract:

    Objectives: To evaluate the outcome of patients with Coronary Perforations who were treated with the dual catheter approach. Background: Coronary Artery Perforation is a grave complication of percutaneous Coronary intervention (PCI) with high mortality and morbidity. Treating a Coronary Artery Perforation with two catheters through dual access enables a rapid delivery of covered stent or coils to the vessel, without losing control of the Perforation site. Methods: We retrospectively reviewed all patients who had a severe Coronary Perforation during a PCI in our center, and compared outcomes of patients treated with the dual versus the traditional single guiding catheter approach. Results: Between April 2004 and October 2008, 13,466 PCI's were performed in Columbia University – New York Presbyterian Medical Center. There were 33 documented cases of Coronary Perforations during that period of time (0.245%), among these, 26 were angiographically severe (Ellis type 2 or 3 Perforations). Eleven patients were treated acutely with a dual catheter technique whereas the other fifteen patients were treated using a single guiding catheter. In the dual catheter group one patient expired after emergent CABG (9.1%), and four patients underwent emergent paricardiocentesis (36.4%). In patients treated with single catheter, there were three deaths (20%), two surgical explorations (13.3%), eight emergent pericardiocenthesis (53.3%), and one event of severe anoxic brain damage (6.7%). Conclusion: The dual catheter technique is a relatively safe and reproducible approach to treat a PCI induced severe Coronary Artery Perforation, and may improve outcome compared to historical series. © 2010 Wiley-Liss, Inc.

  • Coronary Artery Perforation during excimer laser Coronary angioplasty
    Journal of the American College of Cardiology, 1993
    Co-Authors: John A. Bittl, James E. Tcheng, Thomas J Ryan, John F Keaney, Stephen G Ellis, Jeffrey M Isner, Timothy A Sanborn
    Abstract:

    Abstract Objectives. The aim of this study was to analyze the risk of vessel Perforation during excimer laser angioplasty. Background. Vessel Perforation is a serious complication of angioplasty. Methods. A total of 764 patients had 858 stenoses treated with excimer laser angioplasty. Laser catheters had a diameter of 1.4, 1.7 or 2 mm. Laser energy was delivered in pulses of 135 ns, at a frequency of 25 s−1and at a fluence of 30 to 60 mJ/mm2. Follow-up angiography was requested for all patients who did not require emergency bypass surgery. Results. In the 764 consecutive patients treated with excimer laser Coronary angioplasty, vessel Perforation occurred in 23 patients (3%). Nine patients had a major complication resulting directly from vessel Perforation (cardiac tamponade, myocardial infarction or need for bypass surgery) and 14 had no clinical complications after successful sealing of the puncture site. No patient with a Perforation died. Multivariate analysis showed that bifurcation lesions (odds ratio [OR] = 3.5; p = 0.049), diabetes mellitus (OR = 3.15; p = 0.029) and female gender (OR = 2.86; p = 0.013) were associated with an increased risk of vessel Perforation. Lesions >;10 mm in length (OR = 0.45; p = 0.206), calcified stenoses (OR = 0.26; p = 0.088) and saphenous vein graft lesions (OR = 0.50; p = 0.295) were not at increased risk. Vessel Perforation was seen in 10 (8.3%) of 120 lesions in which the laser catheter was equivalent in diameter to the target vessel (≤0.5 mm smaller in size) but in only 8 (1.5%) of 525 lesions in which the laser catheter was >;1 mm smaller than the target vessel (p = 0.001). Conclusions. Most lesions thought to be suitable for excimer laser treatment are not at increased risk of Perforation. The complication may be avoided by improved patient and laser catheter size selection.

  • successful treatment of an excimer laser associated Coronary Artery Perforation with the stack perfusion catheter
    Catheterization and Cardiovascular Diagnosis, 1991
    Co-Authors: John D Parker, Peter Ganz, Andrew P Selwyn, John A. Bittl
    Abstract:

    A 64-year-old woman underwent excimer laser angioplasty of the right Coronary Artery. The procedure was complicated by Perforation, which was successfully managed without complication with a Stack perfusion catheter. This report describes successful nonsurgical treatment of laser-induced Coronary Perforation and makes recommendations for avoiding this complication in other patients.
