Abstract

OBJECTIVES: Rapid-deployment aortic valve replacement (RD-AVR) potentially reduces procedure times providing excellent haemodynamic results compared to standard tissue aortic valve replacement. However, concerns have been raised regarding higher rates of postoperative pacemaker (PPM) requirement compared to standard aortic valve replacement. In this study, we sought to determine the PPM rate and its potential risk factors in RD-AVR patients. METHODS: Between 2011 and 2017, 193 patients underwent RD-AVR. The main outcome investigated was PPM. Other outcome parameters included hospital mortality, major morbidity, length of stay and discharge condition. Predictors of PPM were determined using multivariable regression models. RESULTS: Isolated RD-AVR was performed in 72 (37%) patients and 121 (63%) patients underwent combined RD-AVR [coronary artery bypass grafting (n = 110), mitral repair (n = 6) and others (n = 5)]. Aortic cross-clamp and cardiopulmonary bypass times were 57.1 +/- 25.1 min and 90.0 +/- 40.1 min in the overall RD-AVR population and 39.4 +/- 13.5 min and 67.6 +/- 24.5 min, respectively, in isolated RD-AVR procedures. PPM occurred in 20 (10.4%) patients. Multivariable analysis revealed bypass grafting of the circumflex artery [odds ratio = 2.8] and preoperative right branch bundle block (odds ratio = 11.7) as independent predictors for PPM. CONCLUSIONS: RD-AVR is a safe and simple procedure resulting in favourable short aortic cross-clamp and cardiopulmonary bypass times and considerable low gradients in postoperative echocardiography. PPM following isolated RD-AVR remains in the range of standard aortic valve replacement However, patients undergoing concomitant coronary artery bypass grafting, particularly of the circumflex artery, face a 3-fold increased risk for PPM implantation enhanced if right branch bundle block is present Follow-up examination is necessary to determine whether these patients remain pacer dependent during long-term follow-up.
