Relationship of Preoperative Fasting With Tricuspid Annular Plane Systolic Excursion

Study Overview
=================
Brief Summary
-----------------
The aim of our study is to try to establish a relationship between preoperative fasting-related volume changes and tricuspid annular plane systolic excursion (TAPSE), and to determine whether there are changes in right ventricular functions due to preoperative fasting.

Detailed Description
-----------------
TAPSE (Tricuspid Annular Plane Systolic Excursion) is a parameter that easily measures apex-base shortening and provides specific information about global right ventricular (RV) function. It is less dependent on optimal image quality and serves as an easily measurable criterion compared to other RV function measurements. In this study, one day before the operation, transthoracic echocardiography (TTE) will be conducted on fasting patients, and if the preoperative fasting duration is appropriate on the day of the surgery, TTE measurements will be repeated and recorded. The study aims to evaluate the relationship between TAPSE and volume and determine whether there are any changes in right ventricular functions due to preoperative fasting.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Patients without Cardiac Disease<br>Patients between the ages of 18-65 with sinus rhythm, and without valvular disease, pulmonary hypertension, acute myocardial infarction, dilated, and hypertrophic cardiomyopathy will be included in the study. | Diagnostic Test: Tricuspid Annular Plane Systolic Excursion<br>* Transthoracic echocardiography will be performed on patients during hospitalization and preoperatively to investigate the relationship between preoperative fasting and right ventricular functions. This will be examined by looking at TAPSE<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The TAPSE value is related to volume | We will measure FAC, S' velocity, TAPSE, and Myocardial Performance Index (MPI) derived from TDI to evaluate Right Ventricular (RV) systolic functions. To assess the RV diastolic function, we will measure Tricuspid E and A wave velocities, E/A ratio, and E' velocity. TAPSE will be calculated by placing an M-mode cursor along the Tricuspid Annulus and measuring the longitudinal excursion during peak systole | Patients who apply to our hospital for surgery within 6 months will be included in our study. Preoperative TAPSE measurements will be taken from the patients twice, first during admission and immediately before the operation |
