Key result
Cardiac surgery after radiation requires personalized risk stratification due to multi-structural damage and calcification.
Why the study?
Previous radiotherapy for mediastinal malignancies causes complex post-radiation cardiac injury and severe tissue changes that complicate cardiac surgery and worsen postoperative outcomes. A detailed analysis of pathophysiological mechanisms and clinical and morphological data is needed to facilitate objective risk stratification and optimize personalized perioperative and surgical strategies.
Integrating clinical and morphological data of post-radiation cardiac injury can facilitate objective risk stratification, optimize pharmacological strategies, and improve surgical planning and prognosis for patients undergoing cardiac surgery after mediastinal radiotherapy.

May guide surgical planning in post-radiation cases; leaves open prospective validation of morphological risk stratification.
Radiotherapy (RT) in combined treatment of mediastinal malignancies currently allows for stable remission. Despite improvements in RT techniques aimed at minimizing total focal dose, ionizing radiation still leads to post-radiation cardiac injury (PRCI) with progressive chronic heart failure (CHF) resistant to standard drug therapy. Cardiac surgery is one of the treatment options for consequences of PRCI. Previous RT for mediastinal malignancies predicts worse short- and long-term postoperative outcomes. Complex radiation-induced damage to all cardiac structures (pericardium, myocardium, coronary arteries, valves and conduction system), severe calcification of ascending aorta and pulmonary fibrosis significantly complicate technical aspects of surgery, increase surgery time and risk of intra- and postoperative complications. Obviously, a detailed analysis of pathophysiological mechanisms of PRCI underlies a personalized approach to the treatment of appropriate patients. Clinical and morphological data will facilitate objective risk stratification, creation of an optimized pharmacological strategy, analysis of timing and extent of cardiac surgery aimed at reducing risks and improving long-term prognosis in these patients.

Фролова et al. (2026) conducted a review in Radiation-induced heart disease / post-radiation cardiac injury (PRCI) following radiotherapy for mediastinal malignancies. Cardiac surgery was evaluated on Short- and long-term postoperative outcomes and intra- and postoperative complications. Cardiac surgery for post-radiation cardiac injury is complicated by multi-structural damage and calcification, requiring personalized clinical and morphological risk stratification.
