Clinical and echocardiographic follow-up of patients following surgical heart valve repair or replacement: a tertiary centre experience

Abstract

International best practice guidelines recommend lifelong follow-up of patients that have undergone valve repair or replacement surgery and provide recommendations on the utilization of echocardiography during follow-up. However, such follow-up regimes can vary significantly between different centres and sometimes within the same centre. We undertook this study to determine the patterns of clinical follow-up and use of transthoracic echocardiography (TTE) amongst cardiologists in a large UK tertiary centre. In this retrospective study, we identified patients that underwent heart valve repair or replacement surgery in 2008. We used local postal codes to identify patients within our hospital’s follow-up catchment area. We determined the frequency of clinical follow-up and use of transthoracic echocardiography (TTE) during the 9-year follow-up period (2009–2016 inclusive). Of 552 patients that underwent heart valve surgery, 93 (17%) were eligible for local follow-up. Of these, the majority (61/93, 66%) were discharged after their 6-week post-operative check-up with no further follow-up. Of the remaining 32 patients, there was remarkable heterogeneity in follow-up regimes and use of TTE. This variation did not correlate with the prosthesis type. In summary, the frequency of clinical follow-up and use of echocardiography is highly variable in contemporary practice. Many patients are inappropriately discharged back to their family doctor with no plans for hospital follow-up. These data further support the creation of dedicated specialist heart valve clinics to optimize patient care, ensure rational use of TTE and optimize adherence with best practice guidelines.
