Evaluation of Routine Ear, Nose, and Throat Screening in Heart Transplant Candidates: A Retrospective Cohort Study.

BACKGROUND

Patients with end-stage heart failure refractory to medication can be treated with a heart transplant (HTx). These patients are subjected to a preoperative screening procedure according to International Society for Heart and Lung Transplantation guidelines. Additionally, in our hospital, a routine ear, nose, and throat (ENT) screening is performed, directed toward the identification of asymptomatic infections and head and neck neoplasms. There are no studies demonstrating that this screening has additional value in these patients.

METHODS

To investigate the yield of protocolled ENT screening in candidates for HTx, we retrospectively reviewed the medical records of patients who were subjected to the screening procedure between 2012 and 2020.

RESULTS

The study population consisted of 251 patients of whom 177 (70.5%) were male with a median age of 52 years (IQR, 45-59 years). Ten patients (4.0%) were diagnosed with an infection (sinus) or a neoplasm, resulting in a number needed to screen of 25. In all cases, ENT consultation or sinus radiography did not influence the decision to list patients for HTx. Furthermore, no major ENT infections or occurrence of de novo head and neck malignant neoplasm were observed during follow-up after HTx.

CONCLUSIONS

The clinically relevant yield of protocolled ENT screening in candidates for HTx is low. Based on these findings, we believe that only patients with abnormal findings on a routine sinus computed tomography scan and/or specific ENT complaints should be referred to an otorhinolaryngologist.
