How do I get the values of other columns in the row when an event is raised from a mat-select drop down?

Using angular 7 material I need to get the data for all elements in the row of a mat-table in (during) the selectionChanged event of the mat-select drop down. I can get the selection that changed in the event handler, but I need the values from other columns in the same row in the event handler. Being new to angular I don’t see how to get the data. How do I get the values of other columns in the row that the event was raised from?

.html

<td mat-cell *matCellDef="let element">
  <mat-select (selectionChange)="onNotesChange($event)">
        <mat-option *ngFor="let item of predefinedNotes" [value]="item.id">
          {{item.value}}
        </mat-option>
      </mat-select>
</td>

.ts

onNotesChange(event:any){
     console.log(event);
}

Other answers only show the drop-downs new value, I need other values from the row. For instance there is a usreId column I need the value of in the same row as the mat-select.

Replace [value]="item.id" with [value]="item"

Try like this:

<mat-option *ngFor="let item of predefinedNotes" [value]="item">
     {{item.value}}
</mat-option>
