[Heart transplants. The value of computerized tomography]

Area of Science:

• Cardiology
• Radiology
• Medical Imaging

Background:

• Cardiac transplantation is a complex procedure requiring detailed pre- and post-operative assessment.
• Computed tomography (CT) offers advanced imaging capabilities for evaluating thoracic structures.

Purpose of the Study:

• To evaluate the utility of computed tomography (CT) in assessing morphological changes and complications following cardiac transplantation.
• To determine the effectiveness of CT in visualizing the heart, pericardium, mediastinum, lungs, and pleura in transplant patients.

Main Methods:

• Computed tomography (CT) was performed on 9 out of 12 patients who underwent cardiac transplantation.
• Angio-CT technique was utilized in all patients; ECG-gated CT was used pre-surgery in 5 patients.
• Assessment focused on cardiac morphology, pericardial conditions, and extrathoracic structures.

Main Results:

• CT revealed alterations in atrial morphology, particularly the right atrium, and cardiac rotation.
• Pericardial effusion was detected in 5 patients (3 localized, 2 diffuse).
• CT also identified pleural effusion, pulmonary infections, and mediastinal complications, demonstrating its comprehensive assessment capabilities.

Conclusions:

• Computed tomography (CT) is a valuable tool for evaluating post-cardiac transplantation changes.
• CT provides simultaneous assessment of cardiac, pericardial, mediastinal, pulmonary, and pleural structures.
• The technique aids in the early detection of complications such as pericardial effusion and thrombus.
