    • CIED implant trouble shoot in cath. room Allied Professional Training, THRS 19st, Oct, 2013 黃鴻儒 醫師
    • Classification of Pacemaker Complications by Clinical Presentation Implant related complication Post-implant complication New symptoms secondary to PPM Asymptomatic ECG abnormalities Pneumothorax ( due to subclavian puncture Other complications of subclavian puncture Hematoma Lead perforation Lead dislodgment Lead placement in the systemic circulation Lead fracture Lead insulation defect Loose lead connector Extracardiac stimulation Pacemaker syndrome Pacemaker mediated tachycardia Infection Pain Failure to capture Failure to sense Oversensing (failure to output) Change in paced rate Twiddler syndrome
    • Implantation Techniques - Acute         Pneumothorax Hemothorax Pneumo- hemothorax Brachial plexus injury Arterial puncture Chylothorax Infection Pocket Hematoma / Seroma
    • Acute Venous Stenosis Limiting Access
    • Pneumothorax  In PASE Trial: 1.97%
    • Acute Hemothorax Complicating Subclavian Venipuncture Within 15 minutes of subclavian arterial puncture 3 hours postprocedure
    • Management for Pneumothorax  Suspect lung puncture  withdraw the needle, wait a moment to make certain that a rapid-onset, large, markedly symptomatic pneumothorax is not occurring.  If a pneumothorax does develop, it may not even be apparent radiographically at the end of the procedure.  If a lung puncture has occurred, obtaining another upright chest radiograph 6 hours after completion of the procedure is advisable.  If a pneumothorax has developed, a chest tube or catheter evacuation procedure may be necessary, although frequently, a small to moderate pneumothorax that is not expanding can be managed conservatively without evacuation.
    • Air Embolism during Permanent Pacemaker Procedures  Avoid air embolism (esp. for largebored sheaths)  press proximal end of sheath and instruct patient to hold breath during pacing lead insertion  use of introducer sheath with hemostatic valve
    • Prevention of Air Embolism during PPM Procedures
    • Myocardial Perforation  When recognized, lead MUST be pulled back ?!  Be prepared for tamponade  May require open procedure to manage but heart usually seals itself.
    • Diaphragmatic Stimulation Lead in Cardiac Vein Lead inadvertently placed into post. Cardiac V
    • Implantation Procedure #1 Recorded immediately postimplant. The atrial sensing threshold was 1.8 mV, the ventricular sensing threshold was 12 mV As Vp Vs As Vp Marker of pacemaker What is the cause of this behavior?
    • Implantation Procedure #1 P wave marker is above a QRS As Vp R wave marker is above a Pwave Vs As Vp Leads are switched in the header
    • Implantation Procedure #2 The tracing shown below was recorded with the pacemaker in the DDD mode, 4 V output on both atrial and ventricular channels, base rate 60 ppm and AV delay 165 ms. What is the problem if any? Surface ECG Marker A IEGM A : A pacing V : V pacing
    • Implantation Procedure #2 Loss of V-capture, Patient is in a 2:1 heart block, need to recheck the V lead position. Loss of V capture A : A pacing V : V pacing Loss of V capture Loss of V capture Loss of V capture
    • Implantation Procedure #3 The device is hooked up and the following ECG is seen. Is this normal? If not, what is occurring? A : A pacing P : A Sensing V : V Pacing R : V Sensing
    • Implantation Procedure #3 Good A capture A pacing with V sense to follow A pacing with V sense to follow
    • Implantation Procedure #3 PVC falls upon the AP which V pacing follows inducing the loss of AV synchrony PVC PMT
    • Pacemaker-Mediated Tachycardia  Initiated by a loss of AV synchrony      PVC most common cause Atrial loss of capture Atrial undersensing PAC Magnet removal Retrograde P Ventricular Channel Must Respond PMT at Max Track Rate (or Slower)
    • How to terminate PMT     Place magnet Change to VVI (Use programmer) Program longer PVARP (Use programmer) Use PMT termination algorithm (pacemaker function) Retrograde P PMT terminated Auto-Detect Algorithm
    • Implantation Procedure #4 This ECG strip is handed to you post implant. What is the most likely diagnosis?
    • Implantation Procedure #4 1. A pacing and accompany with captured QRS, it indicated A lead dislodge to ventricle. 2. No V captured waveform followed by V pacing spike due to ventricular is in the physical refractory. 3. On occasion, AV delay is short because of safety pacing. Short AV delay (120 ms) : Safety pacing Normal AV delay Ap Vp Ap Vp Ap Vp Ap Vp Ap Vp
    • Implantation Procedure #4 atrial lead in the ventricle
    • Pulse Generator Pocket- Chronic  Pain - pocket neuralgia     Erosion     Incorrect tissue plan Incorrect location - too lateral Smoldering infection Pressure necrosis Smoldering infection Migration Twiddler’s Syndrome
    • Bipolar  In-line Bipolar conductor construction  Two Coils  Will have several strands  Trifiler, Quadrafiler, 5 filer, etc. Inner insulation  Two layers of Insulation Outer insulation Outer coil (Anode) Inner coil (Cathode )
    • Conductor Coil Fracture
    • Implantation Techniques - Late  Rib-Clavicle crush Insulation damage Conductor fracture  Tight anchoring sleeve Insulation damage Conductor fracture  Loose anchoring sleeve Lead dislodgment Twiddler’s Syndrome
    • Rib-Clavicle Crush Insulation Damage Insulation is radiolucent, deformity in conductor coil identifies location of problem
    • Rib-Clavicle Crush- Conductor Fracture Dotted line identifies lower edge of clavicle
    • Loose Anchoring Sleeve Twiddler’s Syndrome
    • Loose Anchoring Sleeve  Lead allowed to “pull back”  Traction at electrodetissue interface causes high thresholds  Predispose to dislodgment Note loss of heel on leads
    • Loose Anchoring Sleeve Dislodgment Dual Lead July 2001 Day 1 postimplant Day 3 postimplant
    • Tight Anchoring Sleeve Damage to Lead
    • Tight Anchoring Sleeve  Leads from 4 different mfg’s  Tight anchoring sleeve pushes insulation between conductor coils “pseudofracture”  Areas of major stress
    • Pacemaker Lead Placement  Myocardial perforation (Pacemaker lead perforation rate: 0.1~0.8%, ICD lead perforation rate : 0.6~5.2%)  Placement in left ventricle via  Patent foramen ovale  Septal perforation  Arterial entry  Dislodgment: The most common complication( PAcemaker Selection in Elderly : 2.2%)  Atrial dislodgment : 3%  Ventrical dislodgement : below 2%  Diaphragmatic stimulation  Directly - lead in cardiac vein  Directly - myocardial perforation  Indirectly - phrenic nerve stimulation
    • Thrombotic Problems  Venous thrombosis Superior vena cava syndrome   Pulmonary embolism Systemic embolism Endocardial lead on left side of circulation Paradoxical embolism
    • Venous Thrombosis Chronic thrombosis with collaterals SVC Syndrome
    • Chronic Venous Thrombosis  Superficial dilated veins in upper extremity and chest  Localized to side of chest where pacemaker is located  No specific treatment July 2001
    • Superior Vena Cava Syndrome  Symptoms  Swelling of arms  Fullness in head & neck  Increased JVP  Management  Anticoagulation  Surgical reconstruction  Lead explantation  Venoplasty & Stent placement “Beaver Syndrome”
    • Management of Pocket Hematoma  Observation and close follow-up  Soft  Minimal to no tenderness  Surgical evacuation  Tense pocket threatening suture line  Weeping suture line  Severe pain  Immunocompromised host August 2001
    • Pulse Generator Pocket - Chronic  Pain - pocket neuralgia Incorrect tissue plane Incorrect location - too lateral Smoldering infection  Erosion Pressure necrosis Smoldering infection Incorrect location too lateral too superficial   Migration Twiddler’s Syndrome
    • PAIN Incorrect Tissue Plane Furman S, PACE 2001; 24: 1224-1227
    • Proper Location of Pulse Generator Note the use of the Cephalic Vein! Pocket is then placed medial to the incision on the anterior chest wall. Furman S, PACE 2001; 24: 1224-1227
    • Improper Location of Pulse Generator If the pacemaker is placed too lateral, it will cause discomfort every time the patient rotates arm forward Furman S, PACE 2001; 24: 1224-1227
    • Pressure Necrosis Thinning and discoloration at lateral margin Total breakdown and 2° Infection
    • Smoldering Pocket Infection with draining fistula  Presented 2 years post implant  Eschar and draining fistula at edge of incision, surrounding erythema  Waxed and waned on oral antibiotics  Local cultures were negative January 24, 2002
    • Chronic Smoldering Infection Pulse Generator Explanted but Not Lead  Low grade pocket infection  Managed by explanting pulse generator but leaving lead in place  2 weeks of antibiotics  Initial good result  MUST remove all foreign material from pocket 9 months post-PG explant
    • Pacemaker Extrusion Clinical history: 61 year old man implanted 9 months previously for complete heart block. Did not consider follow-up to be necessary. Not concerned when device began to show through the skin. Only when it fell out did he call his physician. Cultures grew Staph epidermidis. Unknown if a primary infection caused the erosion or the site was secondarily infected once it was open to the skin. Parsonnet V, Circulation 2000; 102:
    • Electromagnetic Interference  Electromagnetic Interference (EMI) involves electrical and/or magnetic signals in the environment or arising from the body that impact the normal function of the implanted pacing system.
    • Community Based EMI Influences       Microwave ovens Cellular telephones Electronic article surveillance Power stations Arc welding equipment CB and Ham Radio equipment
    • Hospital Based EMI Influences  Cardioversion and Defibrillation External Internal      Electrocautery Transcutaneous Electrical Nerve Stimulators (TENS) Magnetic Resonance Imaging (MRI) Radiation Therapy (XRT) Electroconvulsive Therapy (ECT)
    • Potential Effects of EMI  Temporary Noise mode reversion Inhibition - sensing Programming change  Permanent Damage to pulse generator Tissue damage at electrode -myocardial interface Increase in capture threshold Increase in sensing threshold Lead damage Patient injury
