    Permanent Pacemaker Implantation Following Cardiac Surgery: Indications and Long-Term Follow-Up

    Background: Conduction disturbances requiring permanent pacemaker implantation after heart surgery occur in about 1.5% of patients. Early pacemaker implantation may reduce morbidity and postoperative hospital stay. We reviewed our experience with patients undergoing surgery to try and identify predictors for pacemaker requirements and patients who will remain pacemaker dependent. Methods: We performed a retrospective review of 4,999 patients undergoing surgery between the years 1993 and 2005. Patient age was 64 ± 12 years, and 71% were males. Coronary bypass was performed in 4,071 (81%), aortic valve replacement in 675 (14%), and mitral valve replacement in 968 (18%) patients. Results: Seventy-two patients (1.4%) required implantation of a permanent pacemaker after surgery. Indications for pacemaker implantation included complete atrioventricular block in 59, symptomatic bradycardia/slow atrial fibrillation in nine, second-degree atrioventricular block in two, and other conduction disturbances in two patients. Predictors for pacemaker requirement by multivariate analysis were left bundle branch block and aortic valve replacement (P < 0.001). Late follow-up was available in 58 patients, at 72 ± 32 months. Thirty-seven (63%) were pacemaker dependent. Predictors for late pacemaker dependency were third-degree atrioventricular block after surgery and preoperative left bundle branch block (P < 0.001). Conclusions: Patients at high risk for pacemaker implantation after heart surgery include those with preexisting conduction disturbances, and those undergoing aortic valve replacement. Of those receiving a pacemaker, about one-third will recover at late follow-up. For patients in the high-risk group who are pacemaker dependent after surgery, we recommend implanting a permanent pacemaker at 5 days after surgery, thus enabling early mobilization and early discharge.

    Left Ventricular Pseudoaneurysm Developing as a Late Complication of Coronary Artery Bypass Grafting with Apicoseptal Plication

    Left ventricular pseudoaneurysm is a false aneurysm, which results from a left ventricle rupture contained by adherent pericardium or scar tissue. The most common etiology of left ventricular pseudoaneurysm is acute myocardial infarction but one-third of pseudoaneurysms develop following surgery. We present a case report of a patient who developed a false aneurysm of the left ventricle 2 months following surgical repair of a left ventricular aneurysm with a concomitant coronary bypass.

    ACQUIRED CARDIOVASCULAR DISEASE Original Articles: A Prospective Observational Study to Compare Conventional Coronary Artery Bypass Grafting Surgery with Off-Pump Coronary Artery Bypass Grafting on Basis of EuroSCORE

    Off-pump coronary bypass (OPCAB) surgery has become a widely used technique during recent years. EuroSCORE risk scale is the most rigorously evaluated scoring system in cardiac surgery to preoperatively quantify the risk of death and other serious postoperative complications. The aim of this prospective observational study was to compare the mortality and morbidity between OPCAB and conventional CABG in three major preoperative groups as assessed by EuroSCORE. Material and Method: All consecutive patients undergoing isolated coronary artery bypass surgery between January 2003 and December 2004 at Wellington Hospital were included. In this period, 347 patients had conventional CABG and 254 patients had OPCAB. Data were prospectively collected according to Australasian Society of Cardiothoracic Surgeons' cardiac surgery data set. The preoperative additive EuroSCORE was computed in each patient and the patients were divided into three risk groups. Results of OPCAB and conventional CABG were compared on basis of EuroSCORE group. Results: OPCAB surgery is preferably performed in patients with low-risk. OPCAB group had lesser number of grafts per patient. When adjusted with risk score, there was no statistically significant difference in mortality in any of the three groups. No significant difference was found for stroke, renal dysfunction, atrial fibrillation, re-exploration for bleeding, deep sternal wound infection, or pulmonary complications in either of three groups. However, inotropic requirement and requirements of blood products were less in OPCAB group. Conclusion: OPCAB does not offer any significant advantage in terms of mortality and morbidity over conventional CABG.,(J Card Surg 2010;25:495-500) [source]

    Such complication is potentially dangerous. We present two cases of an entrapped fractured guidewire during angioplasty. They were managed by urgent coronary bypass. [source]
