  • 5. NURSING CARE GUIDELINES FOR PERCUTANEOUS CORONARY AND VALVULAR INTERVENTIONSMy Dear Colleagues,Despite the passage of a very short time since the foundation of TSC theCardiovascular Nursing and Technicianship Group has spared no effort to publish‘’Nursing Care Guidelines in Cardiac Failure, Acute Coronary Syndromes andHypertension’’ in 2003 and ‘’Nursing Care Guidelines in Percutaneous Coronaryand Vascular Interventions’’ in 2004. These two publications have been well-received and distributed to all of our members. As the stocks have run out it hasbeen necessary to republish the present new editions for the benefit of our newmembers and especially the nurses and the technicians. In this context I am happyto anounce that our study group is working on a new guideline publication.I do believe that the representation of these guidelines prepared with greatdiligence by nurses and specialist cardiologists will be of great use to ourmembers. I would like hereby to reitirate my thanks to all of our contributingmembers.I would like to take this opportunity to emphasize that the educational programsstarted by the Cardiovascular Nursing and Technicianship Group, theirparticipation in other activities of TSC as well as making their presence felt in theEuropean Cardiology Association has been recognised with great appreciation.Our association will continue to give them all the possible support.Looking forward to many more successful cooperations and with best regards,Prof. Dr. Çetin ErolTSC President

  • 7. NURSING CARE GUIDELINES IN PERCUTANEOUS CORONARY AND VALVULAR INTERVENTIONSINTRODUCTIONCoronary heart diseases constitute the most important health problem affectingpeople of productive age.(1-3) Mortality due to cardiovascular diseases is one of the leading causes of death,in spite of all the preventive and therapeutic improvements and new methodsdeveloped in this field.(4) Since cardiovascular diseases continue to be the mostimportant cause of mortality and morbidity, there is intense research on this subjectand different treatment methods are being developed. Therefore increasing numberof patients are undergoing diagnostic and therapeutic interventions in the invasivecardiology laboratory.(1-3) Therapeutic percutaneous coronary artery interventions(non-surgical, done via skin route) have been performed since 1980s in the worldand since 1986-87 in our country with an increasing rate since 1995.(5)1. PERCUTANEOUS CORONARY INTERVENTIONS1.1. Percutaneous Transluminal Coronary Angioplasty (PTCA): PTCA isan invasive procedure used to eliminate stenosis in the coronary arteries by insertiona catheter through the skin and moving forward through the veins. At the last stage,a balloon catheter is inserted in the coronary arterial lesion and the balloon isinflated at the level of occlusion to open the lumen.(3,6-13)1.2. Percutaneous Coronary Atherectomy: Atherectomy tools providealleviation in symptomatic patients with coronary artery disease (CAD) by twoprimary mechanisms:(1) Decreasing the stenosis and increasing the distensibility(compliance) of the artery by partial removal of the atherosclerotic plaque,(2)widening the artery at the level of plaque formation.(1,4,6,10,13-16)Partial removal of the plaque material by atherectomy and decreasing theresistance of the plaque by dilation renders a smoother and a more regular lumenthan achieved by angioplasty.(17)1.3. Percutaneous Coronary Laser Angioplasty: Laser (light amplificiationby stimulated emission of radiation) is a high-energy artificial light. One of thevarious forms of laser beam is “excimer” laser which is used in plaque ablation incoronary arteries.(1,10,13-16,18)1.4. Placement of Percutaneous Coronary Stent: Stents are tubular metal-webs placed to maintain or increase vascular patency obtained by balloonangioplasty.(9,11,12,19)Coronary stents are used to achieve one of two important aims. First, to increasearterial patency achieved by balloon angioplasty and second to minimize the riskof restenosis. Recently new stents have been developed for thispurpose.(6,8,13,14,16,18,20,21)8
  • 8. NURSING CARE GUIDELINES IN PERCUTANEOUS CORONARY AND VALVULAR INTERVENTIONS1.5. Brachytherapy: Brachytherapy is a new and developing technique. It is performedto decrease the risk of restenosis after stent placement or balloon angioplasty.(22)2. PERCUTANEOUS VALVULAR INTERVENTIONS (PVI)PVI is a therapeutic procedure performed by using balloons of appropriate size forthe dilation of stenotic valves.(6,8,13,14,20,23-25)3. RISK FACTORS IN PERCUTANEOUS CORONARY OR VALVULAR INTERVENTIONS(26)A- Patient characteristicsa- Previous history of MI (shorter the time between MI and the procedure, higher is the risk),b- Functional capacity of NYHA III or IV,c- High burden of atherosclerotic plaques,d- Having multiple risk factors,e- Very young or very old age, female gender,f- Hemodynamic instability, shock, renal insufficiency, peripheral artery disease, diabetes mellitus,g- Use of intraaortic balloon pump, previous history of coronary artery intervention, multi-vessel disease, previous history of CABG.B- Surgeon characteristicsa- Lack of knowledge, skill, experience and attention,b- Inadequate or inappropriate information given, preparation or follow-up of the patient.C- Institutional characteristicsa- Quantitative or qualitative inadequacy of equipment and tools,b- Insufficient surgical support. Some of the risk factors may be diminished, but total risk can never be reducedto zero in any institution.4. COMPLICATIONS IN PERCUTANEOUS CORONARY AND VALVULAR INTERVENTIONS(11,12,16,18-20,25,27,28)4.1. Major Complications- Acute reocclusion (PTCA)- MI (PTCA, PVI)- Emergency Coronary Artery By-Pass Graft Operation (CABG)- Rhythm and conduction disorders reducing cardiac output significantly (cardiac arrest etc.) (PTCA, PVI)- Severe bleeding in the groin (PTCA, PVI) 9

NURSING CARE GUIDELINES IN PERCUTANEOUS CORONARY AND VALVULAR INTERVENTIONS- Accidental dissection of the valvular ring (PVI)- Cardiac tamponade due to rupture or tear in the wall of coronary artery or heart chambers (PTCA, PVI)- Acute heart failure (PVI)- Death4.2. Minor Complications- Side branch occlusion (PTCA)- Ventricular/atrial arrhythmias (PTCA, PVI)- Bradycardia (PTCA, PVI)- Left-to-right shunt (PVI)- Hypotension (PTCA, PVI)- Blood loss (PTCA, PVI)- Arterial thrombus (PTCA)- Coronary embolism (PTCA)- Emergency recatheterization (PTCA, PVI)- Severe blood loss requiring transfusion (PTCA, PVI)- Ischemia in the cannulated extremity (PTCA, PVI)- Decrease in renal functions due to contrast medium (PTCA)- Systemic embolism (PTCA, PVI)- Hematoma in the groin, retroperitoneal hematoma, pseudoaneurysm, A-V fistula (PTCA, PVI) (Left) Main coronary Sinus artery branch Aorta Circumflex artery artery Left anterior descending Right Conus branch coronary artery First obtuse Posterolateral marginal branch Right branch ventricular Posterior descending artery branch Second obtuse marginal branch First diagonal branch Second diagonal branch Coronary arteries and branches10
  • 10. NURSING CARE GUIDELINES IN PERCUTANEOUS CORONARY AND VALVULAR INTERVENTIONS5. NURSING CARE IN PERCUTANEOUS CORONARY AND VALVULAR INTERVENTIONS Responsibilities of the nurse involved in the care of the patient undergoinginterventional therapy;1- Prevention and early diagnosis of potential complications,2- Education of the patient and the family,3- Rehabilitation. Prevention and early diagnosis of potential complications, individualized andstructured care, education of the patient and his/her family, modification of riskfactors and life style changes are the most important factors affecting prognosis ininterventional treatment.(9,11,12,17,19) It is important for the nurse to follow recent advances and published literatureand join nursing seminars for the improvement of her knowledge aboutindividualized and structured patient care and education of the patient and thefamily. Nursing care in percutaneous and valvular interventions are similar.(20,24) Careis given in the context of nursing process. Nursing diagnoses are made accordingto medical and nursing history of the patient, physical examination, hemodynamicfollow-up, analysis and interpretation of data including the results of diagnostic tests;care is planned and reassessed.(29-32) 11

Patient/Family Education Before Discharge(20,21,25,31,35,36,38,39,42-46)After discharge the patient is planned to be able to take care of the site ofintervention, to recognize symptoms and signs of complications and to developbehaviour aiming to reduce risk factors.A. Giving General Information• Information on the procedure to be performed and on the results is given,• Level of information given during the training before PTCA/PVI is checked and missing issues or misunderstood subjects are identified and the education is repeated when necessary,• One of the family members should be ready for assisting the patient during hospital discharge.B. Symptoms and Signs that Should be Reported Symptoms and signs of emergency situations, information on possiblecomplications are overviewed and the patient is told to admit to a health carefacility if one of these conditions is present. The patient is told to inform the nurse in the presence of the following conditions;• Continuing chest pain (pain not alleviating despite use of nitroglycerine 3 times with intervals of 15 minutes and lasting more than 15 minutes),• Irregularity of pulse, light headedness,• Weight gain of 1-2 kg/day or 3-5 kg/week,• Lack of energy and fatigue,• Shortness of breath with minimal physical effort,• Changes at the site of intervention (except slight ecchymosis and firmness) - Recent bleeding at the site of cannula insertion, - A recently forming and growing swelling, - Redness, swelling, discharge or feeling of warmth at the extremity on which the procedure is performed, - Insensitivity, numbnessC. Special Considerations The patient is told that;• He/she would better have assistance when going home after hospital discharge,• He/she can remove the gauze pad at the site of insertion one day later,• He/she can take a bath without rubbing the site of intervention (if the permission to take a bath is given)• Tight clothes should be not worn until the sensitivity at the site of intervention diminishes,• Protective bandage can be used if the underwear touches the site of intervention.24
  • 24. NURSING CARE GUIDELINES IN PERCUTANEOUS CORONARY AND VALVULAR INTERVENTIONSD. Mobility• Avoidance of intense activity for the first week (swimming, running, biking, dancing, climbing up the stairs etc.),• Protection of the site of cannula insertion from trauma.The patient is told;• Not to carry, push or pull heavy objects for the first 2-3 days,• Not to drive for at least one week,• To avoid ascending the stairs for the first 2 days (if obligatory, the leg contralateral to the limb on which the procedure is performed is advanced first placing it on the step above and than the other leg is advanced up to the same step,• To avoid sexual activity for 2-3 days following the intervention,• To avoid constipation and straining and to inform the physician/nurse about these symptoms,• When to start working (usually one week later).E. Medical treatment The following explanations are made:• Name of the medication and why it is used,• How many mgs of drug each tablet or capsule contains,• How many times a day and how the medications will be used,• How and where the medications should be kept,• Most common side effects and the importance of reporting them to the physician/nurse when they occur,• Importance of regular use and avoidance of missing doses,• Importance of not ceasing the medication without consulting the physician.F. Modification of risk factorsSaves more lives than all therapeutic interventions. See Guidelines for Preventionand Treatment of Coronary Heart Diseases 2002 and Nursing Care Guidelines forHeart Failure - Acute Coronary Syndromes - Hypertension 2003 for more details. Diet: Low-cholesterol diet according to the physicians recommendations; weightloss is recommended if necessary, Physical activity: Importance of compliance with the physiciansrecommendations on physical activity is explained, Smoking: Importance of quitting smoking is emphasized, Alcohol consumption: Avoidance of excessive consumption is recommended.Patient-specific limits are determined by the physician, 25
  • 25. NURSING CARE GUIDELINES IN PERCUTANEOUS CORONARY AND VALVULAR INTERVENTIONSG. Importance of regular visits for maintenance of well-being is explained to the patient and the family.• For continuity of the education, written materials (booklet, brochure etc.) on patient care are provided for the patient and the family,• Names and phone numbers of the physician and the nurse to be called up when needed are given to the patient.6. PULSE ASSESSMENT(49,51)• Presence,• Amplitude (fullness),• Rate,• Rhythm of the pulse are assessed.Presence of pulse is assessed in all arteries from head to toe bilaterally• Carotid arteries (assessed without pressing)• Radial arteries• Femoral arteries• Popliteal arteries• Aa. dorsalis pedis• Aa. tibialis posterior are especially important. Doppler USG can be used if these arteries cannot be palpated.Pulse AmplitudePulse amplitude may give a rough and quick idea on blood pressure and cardiacoutput. Pulse amplitude is scored from 0 to 4. 0 = The pulse is not palpable +1 = The pulse is weak or thready +2 = The pulse is normal +3 = The pulse is bounding +4 = The pulse is hyperkinetic and visible to the eye without palpation, Pulse rate and rhythm are compared bilaterally at the same time.26
  • 26. NURSING CARE GUIDELINES IN PERCUTANEOUS CORONARY AND VALVULAR INTERVENTIONSTable 1: Agents Commonly Used in PTCA and PVI(20,24,30,31,40,44,52-57) Calcium • They inhibit calcium entry to myocytes and smooth muscle cells. Some of antagonists them may decrease myocardial contractility and rate of conduct. They dilate coronary arteries and arterioles. Beta blockers • They decrease heart rate, cardiac contractility and oxygen requirement. Nitroglycerin • They are generally useful for coronary syndromes with chest pain except myocardial infarction. They decrease ventricular filling pressure and systemic vascular resistance and increase collateral flow. Positive • They are used for conditions where myocardial contractility is decreased. inotropic Digoxin, dopamine and dobutamine are the most frequently used agents. agents Dopamine and dobutamine are more often used for severe hemodynamic failure such as cardiogenic shock. Diuretics • They are used to alleviate congestive symptoms. Furosemide, a loop diuretic, is the treatment of choice. Loop diuretics inhibit sodium and chloride reabsorbtion at the ascending proximal part of Henles loop. Atropine • It is an anticholinergic agent that inhibits acetylcholine at the parasympathetic neuromuscular junction. It increases heart rate by decreasing parasympathetic inhibition on sinus node and atrioventricular node. Lidocaine • It belongs to Class Ib antiarrhythmic agents used for ventricular hydrochloride extrasystols that cause symptomatic and hemodynamic impairment. It acts by shortening action potential duration. Antiaggregant • Inhibits cyclooxygenase, an enzyme involved in the synthesis of agents thromboxane A2 which causes aggregation of platelets. Consequently, -Aspirin tendency of platelets to adhere to each other and to vessel walls and to aggregate is decreased. Daily dose is 75-325 mg. Acute treatment dose is 150-300 mg/day and chronic treatment dose is 80-100 mg/day. -Ticlopidine • Inhibits platelet aggregation and release of platelet derived factors. Inhibits binding of fibrinogen to platelet memebrane via ADP. Ticlopidine prevents ADP-induced platelet aggregation. Antiaggregant activity is increased when used concurrently with aspirin. This combined use markedly increased the safety of PTCA and coronary stent placement and extensively decreased early occlusions. -Clopidogrel • Acts like ticlopidine, has less side effects and is generally used for the same indications. Anticoagulant • Prevents thrombus formation at the the site of PTCA by speeding up the therapy synthesis of antithrombin III–thrombin complex. Inactivates thrombin and -Standard prevents the conversion of fibrinogen to fibrin. Duration of its effect is 4 heparin hours and the activity is monitored by aPTT. -Low molecular • They are derived from standard heparin. They have a lower molecular weight heparin weight and are given every 12 hours. There is no need for aPTT control. (LMWH) Some of these agents –enoxaparine– are shown to be superior to standard heparin in acute coronary syndromes. Glycoprotein • They are used for high-risk coronary artery interventions in non-ST segment IIb/IIIa elevation myocardial infarction. They prevent binding of platelets to each Receptor other via fibrinogen bridges by blocking GPIIb/IIIa receptors. Reduction Antagonists of heparin doses should be considered when they are used with heparin -Abciximab or LMWH. -Tirofiban -Eptifibatide 27
