Abstract Objective To assess the effects of trans-tricuspid placement of permanent pacemaker (PPM), on the right-sided heart function and tricuspid valve function. Background Over the last decade there has been a significant increase in the number of cardiac device implantation as permanent pacemakers (PPM) worldwide in patients with cardiac rhythm disorders. Tricuspid regurgitation (TR) due to the endocardial lead is a known complication of this procedure, however the incidence of new or worsening TR had not been well studied. Patients and Methods We reviewed patients who underwent permanent pacemaker implantation in our cardiology department in Ain Shams University. Patients who had pacemaker implantation less than one year ago, had severe tricuspid regurgitation before implantation or had previous tricuspid valve repair were excluded. A total of one hundred patients with an echocardiographic study before and another echocardiographic study at least one year after device implantation were included in our study. TR severity was graded as (0 none/trace, 1 mild, 2 moderate, 3 severe). Results Of the 100 patients (Mean age: 53.10 ± 16.04, 50% of patients were males) 65 had DDD and 35 had VVI. Before implantation 25 patient had trace TR (grade 0) vs. 6 patients after, 75 patients had mild TR (grade 1) vs. 82 after, with no patient had moderate TR (grade 2) vs. 12 patients after. TR worsened by one grade in 25 patients, (16 patients from grade 0 to grade 1 and 9 patients from grade 1 to grade 2) and by 2 grades in 3 patients (from grade 0 to grade 2), Pvalue < 0.01. TR jet area size (Mean ± SD: 2.80 ± 0.77 before vs. 4.15 ± 1.29 after, P-value < 0.01). Also, 99 patients had normal RV size and one had dilated RV before implantation vs. 95 patient had normal RV and 5 had dilated RV (p-value= 0.097). RV size, LVEF (Mean ± SD: 56.41% ± 7.52 before vs. 55.77% ± 8.00 after), RV function by TASPE (Mean ± SD: 19.15 ± 1.00 before vs. 18.96 ± 0.96 after), RVSP (Mean ± SD: 29.48mmHg ± 5.54 before vs. 29.81 ± 5.09 after) and diastolic function by E/A ratio (Mean ± SD: 1.60 ± 0.39 before vs. 1.57 ± 0.38 after implantation) did not show significant change. Conclusion Permanent pacemaker (PPM) implantation is associated with worsening of tricuspid regurgitation. Echocardiography plays an important role in assessing and grading this condition. Further studies are needed in order to illustrate the effects of these finding on patients outcomes.

An Intra-operative Transesophageal Echocardiographic Study to Compare The Effect of Sevourane and Isourane on Left Ventricular Dysfunction In Patients With Ischemic Heart Disease Undergoing Coronary Artery Bypass Grafting Using Cardiopulmonary Bypass Context : Diastolic dysfunction has been increasingly recognized as an important cause of congestive heart failure (CHF) and resultant morbidity. About 50% patients with CHF have 'diastolic heart failure' in spite of a normal systolic function with preserved ejection fraction. The widely used volatile anesthetic agents, Isourane and Sevourane, are considered important components of balanced anesthesia technique. However their effects on left ventricular (LV) systolic and diastolic function have not been precisely dened. This study was designed to quantify and compare their effects on left ventricular function by TEE before start of CPB. Aims : To compare the effects of Isourane and Sevourane on echocardiographic LVsystolic and diastolic parameters. Settings and design : After obtaining institutional ethics committee clearance and informed consent from 60 patients operated within my study period was included . Data were collected after induction and just before going on bypass. Materials and Methods : After inducing the patients with institutional protocol one group was given isourane(Group I) and another group was given sevourane(Group S), both at 1MAC. TEE parameters measuring LVsystolic and diastolic functions were done. Statistical analysis : Data were analysed by Epi Info (TM) 7.2.2.2. Result and conclusion :Isourane was better than sevourane in comparism of systolic and diastolic dysfunction.
