Brief Summary
The proposed study seeks to determine the incidence of dysphagia and vocal fold mobility impairment (VFMI) in individuals undergoing cardiovascular surgical procedures. It also seeks to determine the impact of postoperative swallowing impairment on health-related outcomes.

Outcome Measures
Primary Outcomes (2)
Penetration Aspiration Scale
This scale is a validated measure used by trained blinded clinicians to assign ratings of safety to swallowing bolus trials. The development and use of an 8-point, equal-appearing interval scale (8 being best; 1 being worst) to describe penetration and aspiration events are described. Scores are determined primarily by the depth to which material passes in the airway and by whether or not material entering the airway is expelled. (FEES)
Baseline (Prior to surgery)
Penetration Aspiration Scale
This scale is a validated measure used by trained blinded clinicians to assign ratings of safety to swallowing bolus trials. The development and use of an 8-point, equal-appearing interval scale (8 being best; 1 being worst) to describe penetration and aspiration events are described. Scores are determined primarily by the depth to which material passes in the airway and by whether or not material entering the airway is expelled. (Used in both FEES and VFSS)
Follow-up - Within 72 hours following extubation from surgery and onward
Study Arms (2)
Cardiovascular Surgical Patients Preoperative Exam
All enrolled participants will undergo a baseline Fiberoptic Endoscopic Evaluation of Swallowing (FEES) before their surgery to determine baseline / preoperative swallowing function. Those with confirmed dysphagia will not be asked to complete the postoperative swallowing exam, given our desire to examine contributing risk factors for dysphagia development and mechanisms within cardiovascular surgical patients. In addition to the instrumental exam, systematic collection of demographic, medical, surgical, and intubation-related candidate predictor variables will be conducted over the entire perioperative period.
Cardiovascular Surgical Patients Postoperative Exam
All remaining participants without preoperative dysphagia will be seen for a postoperative exam performed within 48 hours of extubation. Simultaneous imaging using FEES and videofluoroscopy will be performed at the bedside, as well as a battery of clinical tests. Completion of these postoperative tests will indicate study completion for participants without evidence of dysphagia, while participants who demonstrate acute-phase postoperative dysphagia will continue to participate if they desire. During their standard of care one-month follow-up appointment, a third research evaluation will be offered for participants with previously identified postoperative dysphagia. During this exam, the same imaging and clinical tests from the previous research exam will be performed. Finally, participants with persisting dysphagia will be offered the opportunity to continue to be studied for a fourth and final research exam during their standard of care six-month follow up clinic visit.
Interventions
This procedure involves inserting a flexible laryngoscope that contains a light source and video camera on the end through the open passage of the nose towards the back of the throat in order to visualize the swallowing mechanism.
This procedure involves inserting a flexible laryngoscope that contains a light source and video camera on the end through the open passage of the nose towards the back of the throat in order to visualize the swallowing mechanism. The participant will be asked to perform some voicing tasks, once completed, a videofluoroscopic swallowing exam will occur at the same time. This is like moving x-ray of the participant swallowing foods and liquids (barium).
Cough PEF will be performed to index a participant's physiologic airway defense capacity and strength. Testing will occur with the participant seated upright at 90 degrees using an analog peak flow meter with a one-way expiratory valve that prevents a participant from breathing air in from the device to reduce contamination.
Participants will be seated upright and administered reflex cough testing via a disposable adult aerosol mask with an attached nebulizer that contains a solution to elicit a cough response.
Lingual strength will be evaluated using the Iowa Oral Pressure Instrument (IOPI). Participants will be seated upright, and the SLP will place the IOPI air-filled sensing bulb in the midline anterior position on the participant's tongue, posterior to the alveolar ridge.
Speech assessment will occur with the participant comfortably seated headset microphone with a lapel windscreen connected to a TASCAM DR40 to allow for high-quality audio recordings. Individuals will be asked to perform two maximal performance speech tasks that include vowel prolongation of /a/, and a Diadochokinetic (DDK) rate task to examine SMR for production of the word "buttercup."
