Purpose: This study was undertaken to identify the effect of providing information on anxiety, knowledge and compliance in permanent pacemaker patients. Method: A quasi experimental design with non-equivalent control group and non-synchronized design was used. The subjects of this study were 50 patients who had received permanent pacemaker implantation at a university hospital in Seoul. They were divided into an experimental group of 22 patients who received education and a control group of 28 patients. The education was composed of group education(twice) and individualized reinforcement education(once) using an education booklet. Results: Anxiety decreased in the experimental group. Knowledge significantly increased in the experimental group compared to that in the control group. Compliance significantly increased in the experimental group. Conclusion: It can be concluded that providing information is effective for reducing anxiety, increasing knowledge and improving compliance of the permanent pacemaker patients.

Purpose: The purpose of this study was to examine the level of knowledge and learning needs of patients with a permanent pacemaker implantation. Methods: The participants were 86 patients with a permanent pacemaker implantation. Data were collected during April and May 2002 using a questionnaire survey on knowledge and level of learning need. The collected data were analyzed using the SAS program. Results: 1. The average knowledge score was 13.21. The knowledge level was significantly higher in participants under 50 years of age and for those with higher levels of education. The items with the highest knowledge score was 'permanent pacemaker needs regular check ups' and the lowest, 'a bath can be taken 1 month after stitches are removed'. 2. The total average score for learning needs was 60.78 and the mean item score was 3.04 as measured on a 4-point Likert scale. The item showing the highest learning need was 'electrical fields can affect the pacemaker's function and the lowest learning need was for sexual activity after permanent pacemaker implantation'. Conclusion: According to the above findings, it can be concluded that an intensive nursing education program should be developed for patients with a permanent pacemaker especially for those patients over 50 years of age and those with lower levels of education.

Pacemaker therapy has been established as a routine procedure in a variety of disturbances of :cardiac rhythm. Cardiac pacing has greatly reduced the mortality rate in patients suffering from bradyarrhythmias complicated by Stokes-Adams attacks. However, in spite of the simplicity of the treatment and reliability of the devices available today, patients and physicians alike are invovled in a multitde of pacemaker specific problems. Clinical experience with permanent transvenous pacing during a 3 year period is presented. A total of 20 pacemaker operations were performed in 13 patients. The complications in our 20 pacemaker operations were headed by skin ulceration of 3 generator pockets and early dislocation of 3 electrodes. In an additional 2 patient, stimulation of diaphragm due to a position of electrode in the coronary sinus was noticed in one and battery failure of pulse generator was detected in the other. Literatures were reviewed.

During the period from January 1982 to June 1984 we implanted permanent pacemakers in 18 patients who received open heart surgery at Yonsei University Hospital. 1.In 11 patients, open heart surgery was performed at Yonsei University Hospital and new surgical induced heart blocks were developed and implantations of permanent pacemaker were done. 2.Total 1035 open heart surgeries were done and implantations of pacemaker were performed in 11 cases. [1.06%]. After total correction of TOF [215 cases] implantations of pacemaker were done in 3 cases. [1.4%] Implantations of pacemaker were 0.37% after VSD repair, 0.78% after ASD repair, 5.9% after ECD repair, 0.48% after MVR and 2.0% after AVR. 3.Causes were complete A-V block, sick sinus syndrome and A-V dissociation. 4.Heart blocks were developed immediately after bypass stop in 8 patients. 5.Implantations of pacemaker were done at more than 2 weeks after open heart surgery. 6.Local anesthesia was done in adult and general anesthesia in infants. Locations of pulse generator were subxiphoid, subcostal & subclavian. Position of pulse generator was between subcutaneous fat layer and muscle layer. 7.Types of pulse generator were VVI, VDD and AAI. 8.The postoperative complications included infection, pacing failure, sensing failure and lead dislodgment.

Implantation of a permanent pacemaker is a widely accepted procedure for the patient with complete heart block.As a result of these device, the prognosis for patients with Adams-Stokes syndrome caused by complete A-V block and other cardiac arrhythmia have become much more optimistic. Permanent pacemaker implantation by means of a transvenous approach has made the operative risk much less and the procedure simpler. However, a number of complications have been reported in the literature regarding transvenous endocardial pacemaker implantation during the last a decade. The patient presented in this paper is a 26-year old girl who was implanted with a permanent pacemaker at 14 years of age because of a congenital A-V block. Following first exchange of pulse generator, the electrode (lead) was fractured, so that by the pulse generator, a change to the transvenous technique of implantation was made, After this, there were episodes of recurrent wound infection on three occasions, even though the site of pulse generator implantation was exchanged to the contralateral side of chest wall, massive doses of antibiotics were administered and sensitivity tests for coagulase positive staphylococcal infection were performed. Though there was no definite evidence of blood stream infection by blood culture, we decided not to use the transvenous technique and not to implant the pulse generator in the chest wall because the venous system and the entire anterior chest wall appeared to be diseased or contaminated by virulent pyogenic organisms. Finally this intractable systemic and local wound infection was successfully controlled by myocardial lead implantation via a subxiphoid approach and implantation of the pulse generator far down in the abdominal wall. The causes and routes of recurrent wound infection and possible blood born infection in this particular patient are still obscure. We strongly believe that myocardial pacemaker implantation is much safer than transvenous endocardial pacemaker implantation & myocardial pacemaker implantation is a definite method for controlling such an intractable wound infection. following transvenous pacemaker implantation.

Insertion of an epicardial pacemaker is a useful treatment for pediatric patients with an abnormal heart rhythm. However, there are limitations and concerns when implanting epicardial pacemakers in infants and neonates due to their small body size. We report a patient who experienced rare complications after implantation of a permanent pacemaker.

Background: The absence of atrial contraction (AC) after the maze procedure has been reported to cause subsequent annular dilatation and to increase the risk of embolic stroke. We hypothesized that the lack of AC could increase the risk of permanent pacemaker (PPM) implantation in patients undergoing the maze procedure. Methods: In 376 consecutive patients who had undergone a cryo-maze procedure and combined valve operation, recovery of AC was assessed at baseline and at immediate (${\leq}2$ weeks), early (${\leq}1$ year, $4.6{\pm}3.8$ months), and late (>1 year, $3.5{\pm}1.1$ years) postoperative stages. Results: With a median follow-up of 53 months, 10 patients underwent PPM implantation. Seven PPM implants were for sinus node dysfunction (pauses of $9.6{\pm}2.4$ seconds), one was for marked sinus bradycardia, and two were for advanced/complete atrioventricular block. The median (interquartile range) time to PPM implantation was 13.8 (0.5-68.2) months. Our time-varying covariate Cox models showed that the absence of AC was a risk factor for PPM implantation (hazard ratio, 11.92; 95% confidence interval, 2.52 to 56.45; p=0.002). Conclusion: The absence of AC may be associated with a subsequent risk of PPM implantation.

Background: Sutureless aortic valve replacement (SU-AVR) has been developed as an alternative surgical treatment for patients with symptomatic severe aortic stenosis (AS). The aim of this study was to evaluate the clinical outcomes of SU-AVR through an assessment of hemodynamic performance and safety. Methods: From December 2014 to June 2016, a total of 12 consecutive patients with severe AS underwent SU-AVR. The endpoints were overall survival and valve-related complications (paravalvular leakage, valve thrombosis, migration, endocarditis, and permanent pacemaker implantation). The mean follow-up duration was $18.1{\pm}8.6months$. Results: The mean age of the patients was $77.1{\pm}5.8years$ and their mean Society of Thoracic Surgeons score was $9.2{\pm}17.7$. The mean cardiopulmonary bypass and aortic cross-clamp times were $94.5{\pm}37.3$ minutes and $54.9{\pm}12.5minutes$, respectively. Follow-up echocardiography showed good prosthesis function with low transvalvular pressure gradients (mean, $13.9{\pm}8.6mm\;Hg$ and peak, $27.2{\pm}15.0mm\;Hg$) at a mean of $9.9{\pm}4.2months$. No cases of primary paravalvular leakage, valve thrombosis, migration, or endocarditis were reported. A new permanent pacemaker was implanted in 1 patient (8.3%). The 1-year overall survival rate was $83.3%{\pm}10.8%$. Conclusion: Our initial experience with SU-AVR demonstrated excellent early clinical outcomes with good hemodynamic results. However, there was a high incidence of permanent pacemaker implantation compared to the rate for conventional AVR, which is a problem that should be solved.

Fifty seven patients underwent repair of a partial atrioventricular septal defect from January 1980 to December 1986. The ostium primum atrial septal defect was closed with autologous or bovine pericardium. The cleft in the anterior mitral leaflet was present in 53 cases, absent in 4 cases. Of the 53 cases with a cleft in the anterior mitral leaflet, 48 received suture repair of the cleft, 3 received mitral valve replacement. There was no hospital death and all the patients were followed-up for a mean period of 26.4 months. Four required permanent pacemaker implantation due to complete heart block, and one of them died of sudden malfunction of pacemaker. Two received reoperation due to significant residual mitral insufficiency. Suture repair of the cleft in the anterior mitral leaflet resulted in significant decrease in degree of mitral regurgitation. During follow-up period 49 patients were in NYHA class I, 7 patients were in NYHA class II. This report suggests that excellent result can be achieved from repair of the partial atrioventricular septal defect by managing the left A-V valve as a bileaflet structure.

배경: 본 연구에서는 소아연령군에서 과거 13년 동안 시행한 심외막 인공 심박 조율 수술의 임상경험을 바탕으로 인공 심박동기의 평균 수명, 역치, 재수술의 원인 등을 알아보고자 하였다. 대상 및 방법: 1989년 1월부터 2002년 7월까지 영구 심박 조율기 또는 전극의 이식을 시행한 83명의 환아에게 시행한 121예의 수술을 대상으로 하였다. 후향적으로 환자의무기록을 조사하여 심박 조율기의 수명, 자극 역치, 저항, R파, P파, 감지 역치 등을 조사하였다. 결과: 수술 당시 측정한 평균 심실 자극역치는 1.2$\pm$0.l (0.1∼5) mV, 평균 저항은 519.1$\pm$18.1 (319∼778) ohm, 평균 심실 R파 감지역치는 8.9$\pm$0.7 (4∼20) mV, 평균 P파 감지역치는 2.5$\pm$0.7 (0.4∼12) mV 이었다. 심박 조율기의 평균 수명은 64.7$\pm$3.7 (2∼196)개월이었다. 심박 조율기 무재수술률은 1년 94.6%, 2년 93.6%, 5년 80.8%, 7년 63.7%, 10년 45.4%였다. 재수술의 원인은 전지 고갈이 26예, 전극 이상이 9예 등이었다. 심박 조율기 삽입 후 이의 오작동과 관련된 수술 후 조기 사망은 없었다. 결론: 소아연령군에서 심외막 심박 조율기 삽입 후 재수술 없이 이를 사용할 수 있는 비율은 비교적 만족할 만한 수준으로 19.1%의 환자만이 5년 내에 재삽입이 필요했다. 스테로이드 용출 전극의 재수술률은 6.7%로 이는 심외막 심박 조율기의 수명을 늘리는 데 도움이 될 것으로 생각된다.
