The endoscope utilized to visualize the heart and major vessels is the angioscope. This type of endoscope is specifically designed for examination and imaging of blood vessels and the interior of the heart, making it invaluable for procedures related to cardiology and vascular health. The angioscope can provide real-time visualization during procedures like angiography, where assessing the condition of blood vessels is critical.

In contrast, other instruments listed serve different purposes. For instance, a ventriculoscope is used primarily to visualize the ventricles of the brain, not the heart. A bronchoscope is designed for viewing the airways and lungs, focusing on respiratory structures rather than cardiovascular ones. The mediastinoscope is used to examine the mediastinum, the space between the lungs that contains the heart, aorta, and other vital structures, but it is not specifically for direct visualization of the heart and major vessels like the angioscope is.
