Background: Heart failure is a leading cardiac morbidity prevalent across the globe. Its incidence is rising in direct proportion to increasing longevity all over the world. Demographic variables are important predictors of quality of life, morbidity, rehospitalization, and mortality due to systolic heart failure. The objective of our study was to assess the association of demographic variables with quality of life of systolic heart failure in patients presenting at Cardiology Out Patient Department, Hayatabad Medical Complex, Peshawar. Our study aims to inform policy making as it highlights some important demographics factors associated with quality of life. Methods: A cross sectional method was employed in the study to examine systolic heart failure and its prevalence across various demographic variables such as age, gender, marital status, activity, number of children, education, employment status, and BMI at cardiology OPD of a medical teaching institution in Peshawar. Consecutive sampling was used and data were collected through a structured questionnaire from 368 Systolic Heart Failure patients. Data were analyzed using SPSS version 22. Results: We had 368 participants, a majority of whom (n=290; 78.8%), were in NYHA class III. The rest (n=78; 21.2%) were in class IV. Minnesota Living with Heart Failure Questionnaire (MLHFQ) was used to categorize quality of life into 'Good', 'Moderate' and 'Poor'. Most participants were in the 'poor' category with MLHFQ scores >45 (n=193; 52.4%). Those who had scores between 25 -45 were categorized as 'moderate' (n=116; 31.5%), and participants who scored < 24 were categorized as having a 'good' quality of life (n=59; 16%). Reliability of tools was checked by Cronbach alpha which was 0.86 Conclusion: It was concluded that demographic variables have a significant effect on the overall morbidity of heart failure patients and heart failure related quality of life.

Background: With increased rate of permanent pacemaker's (PPM) implantation, the rate of complication also increased many folds. Infection in pacemakers is one of the dreaded complications which need a multidisciplinary approach in its management. Methods: All patients with permanent pacemakers, who presented with infection of device, were admitted in our unit. The infected device was explanted and wound left open. The same device was used as a temporary pacemaker with a new PPM screwing lead from internal jugular approach. Once the infection was under control, a new device was implanted on the other side and temporary wire (PPM screwing lead) pulled out. Wound on both side closed and patient kept on antibiotics for a week. Results: Total 10 cases of infected device received. Single chambers devices with infection were six and dual chamber pacemakers were four. One case with infection had tine lead and nine patients presented with screwing leads. Male and female ratio was 2.3:1. All leads were explanted in our department with conventional gadgets using rotation and traction maneuvers. Culture sensitivity in all cases remained negative. Patients were kept on broad spectrum antibiotics till the wound was clear. One patient had small pericardial effusion soon after explantation of tine lead, which was treated conservatively. No other major or minor complication documented. Conclusion: Scrupulous planning and preparation before system extraction and later on new Cardiac implantable electronic device re-implantation is essential for better patient outcome.

Overall life span has increased with improved management of cardiac diseases all over the world which has opened the door of degenerative cardiac diseases. On the other hand, stat of the art corrective congenital cardiac disease also increased the volume of adult living with treated congenital heart diseases. Both these factors lead to a new epidemic in cardiology of complete heart block (CHB). Permanent pacemakers (PPM) implantation is a life-saving procedure for CHB. Permanent pacemakers are usually implanted from upper limb veins. But at time upper limb veins are not suitable for implantation due to various anatomical and pathological reasons, so alternative methods are used for implantation of devices. We are reporting a case of PPM implantation from Superior Vena Cava (SVC). [ABSTRACT FROM AUTHOR]

Background: Atrioventricular nodal re-entrant tachycardia (AVNRT) is still the most common presentation to our electrophysiology laboratory for ablation. The aim of this study is to document the confirmative value of cross over manoeuvre in successful AVNRT ablation., Methods: This study was conducted in Hayat Abad Medical complex Peshawar June 2006 to October 2015. In all patient with AVNRT, Dual-nodal pathway physiology confirmed by programmed atrial pacing of eight Tran with an extra beat by 10 millisecond (ms) decrement and at least Atrial HIS (A-H) interval prolongation of 50 ms. The dual pathway was further confirmed by cross over manoeuvre. Slow pathway potential identified and radiofrequency ablation (RFA) energy applied at 60 temperatures and 30 powers in Left Anterior Oblique (LAO) projection. Post ablation absence of cross over documented with and without isoproterenol and patient followed for any complication or recurrence., Results: Total 567 patients studied with mean age 36.56±12.16 and male to female ratio 1:1.4 with presentation of supraventricular tachycardia (SVT). Slow pathway was successfully modified and statistically no significant complication or recurrence documented., Conclusions: Failure to cross over reliably excludes any conduction over the slow pathway and so recurrence of AVNRT.

Background: Device implantation is an integral part of interventional cardiology particularly electrophysiology. In this study, we are going to shear our experience of device implantation technique at electrophysiology department Hayatabad Medical Complex, Peshawar., Methods: The study was conducted from June 2011 to December 2015. Axillary vein was used to implant the devices but in some cases when this rout was not convenient due to any reason then subclavian vein was entered through the Seldinger technique. Fluoroscopy time was less than 10 minutes and total procedure time was not more than 45 minutes. Electric cautery was used only in two cases. Pressure dressing was used in a few cases., Results: Total numbers of permanent pacemakers (PPM) remain 800 during the study period. There were 450 single chamber pacemakers and 350 dual chambers pacemakers. No case of any major bleeding was documented and in very few cases there was mild ooze from the procedure site after the operation which was tackled with pressure dressing. Four cases of pneumothorax were noted during the study period and in three cases chest intubation were done and one patient was kept on conservative management. Patient were followed after one moth of discharge from the hospital and then yearly. Eight cases of lead dislodgment were documented during the study period., Conclusions: Axillary vein approach for implantation of permanent pacemakers is a safe and less time-consuming technique.

Background: To ablate accessory pathway successfully and conveniently, accurate localization of the pathway is needed. Electrophysiologists use different algorithms before taking the patients to the electrophysiology (EP) laboratory to plan the intervention accordingly. In this study, we used Arruda algorithm to locate the accessory pathway. The objective of the study was to determine the accuracy of the Arruda algorithm for locating the pathway on surface ECG., Methods: It was a cross-sectional observational study conducted from January 2014 to January 2016 in the electrophysiology department of Hayat Abad Medical Complex Peshawar Pakistan. A total of fifty nine (n=59) consecutive patients of both genders between age 14-60 years presented with WPW syndrome (Symptomatic tachycardia with delta wave on surface ECG) were included in the study. Patient's electrocardiogram (ECG) before taking patients to laboratory was analysed on Arruda algorithm. Standard four wires protocol was used for EP study before ablation. Once the findings were confirmed the pathway was ablated as per standard guidelines., Results: A total of fifty nine (n=59) patients between the age 14-60 years were included in the study. Cumulative mean age was 31.5 years±12.5 SD. There were 56.4% (n=31) males with mean age 28.2 years±10.2 SD and 43.6% (n=24) were females with mean age 35.9 years±14.0 SD. Arruda algorithm was found to be accurate in predicting the exact accessory pathway (AP) in 83.6% (n=46) cases. Among all inaccurate predictions (n=9), Arruda inaccurately predicted two third (n=6; 66.7%) pathways towards right side (right posteroseptal, right posterolateral and right antrolateral)., Conclusions: Arruda algorithm was found highly accurate in predicting accessory pathway before ablation.

Background: Temporary pace maker (TPM implantation is done mostly in emergency with assistance of fluoroscopy. Fluoroscopy has various constrains which may delay the procedure at different occasion. We are going to share our experience in TPM implantation without fluoroscopy from internal jugular vein., Methods: The case series study was conducted in Hayatabad Medical complex Peshawar from January 2011 to November 2011. Internal jugular vein was cannulated with 6 French sheaths in the supra-clavicular region with modified Seldinger technique. TPM wire connected to the TPM device and advanced in the sheath to the right ventricle. Position was confirmed from captured beat on monitor. There was no need of repositioning and lead remains stable., Results: Total 122 TPM leads were implanted in the study period. All patients were implanted from internal jugular vein. There were 71 male and 51 female patients. Among these patients 55 were in hemodynamically unstable state. The average time of implantation was less than 10 minutes. There was failure in one case. So the overall success rate was 99.180%., Conclusion: TPM implantation from the internal jugular vein even without fluoroscopy is safe, less time consuming and convenient.
