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

Abstract

(PACE 2009; 32:7-12) permanent pacemaker, cardiac surgery IntroductionThe incidence of conduction disturbance requiring pacing after open heart operations is between 10% and 15%. [1][2][3][4] Most of these will recover, however, 1-3% of patients will require permanent pacemaker implantation. [5][6][7] We reviewed our experience with permanent pacemaker (PPM) implantation following cardiac surgery. Our aim was to identify predictors for PPM requirement and identify patients who will remain pacemaker dependent over long term.

Bloqueio atrioventricular no pós-operatório de cirurgia cardíaca valvar

“…The incidence of disorders of atrioventricular (AV) in the post-cardiac surgery (POCS) valve is located, according to the literature, 10 to 15% [1]. Most patients have disturbances of a temporary nature and will require temporary cardiac pacing (DPM), but 1% to 3% of patients, given the irreversibility of the framework, will be subject to a definitive pacemaker (DPM) during hospitalization [1][2][3]. In this study, we analyzed the experience of more than 1100 valve surgery procedures in order to verify the relationship between factors pre-, intra-and postoperative (perioperative) associated with atrioventricular block (AVB) and the need for TAC with later implant DPM on POCS.…”

Effects of Positive End-Expiratory Pressure on Mechanical Ventilation Duration after Coronary Artery Bypass Grafting: A Randomized Clinical Trial

“…As one of the mechanical ventilation parameters, positive end-expiratory pressure (PEEP) contributes to improved oxygenation and prevention of atelectasis, maintains positive pressure in the airway, promotes recruitment and stabilization of alveoli and small airways and reduces pulmonary shunting and increases functional residual capacity, avoiding alveolar collapse. 3,[9][10][11][12][13] We compared the effects of different levels of PEEP on mechanical ventilation duration after coronary artery bypass to identify parameters that could indicate early withdrawal of mechanical ventilation.…”

The 30 Day Complication Rate After Aortic Valve Replacement with a Pericardial Valve in a Mainly Geriatric Population

“…Sometimes, a new conduction defects could be reversible (58). Development of a new conduction defects resulted to an increased need for monitoring and hence a longer hospital stay (60) The main predictor for permanent pace maker implantation in other series were preoperative conduction defects (58,(61)(62)(63). Other predictors were female gender, annular calcification, bicuspid aortic valve, hypertension, myocardial infarction, electrolyte imbalance and prolonged cross-clamping time (60,64,65).…”
