Figura 1
Figura 1. – Planejamento da radioterapia. Foram analisadas as morfologias das taquicardias ventriculares induzidas no estudo eletrofisiológico (A), e o local da saída foi marcado na reconstrução tridimensional da tomografia, uma vez os locais da saída foram marcados foi realizado o planejamento da área a ser irradiada (B). A área definida foi então manualmente marcada no sistema de radioterapia (C), que fez o cálculo das doses de tolerância (constraints) de cada estrutura vizinha (D).

Figura 2. – Linha do tempo e gráfico de colunas com o número de terapias em cada mês (coluna azul antes e verde após radioterapia) e os momentos das ablações (linha vertical azul) e radioterapia (linha vertical vermelha). Em laranja estão os momentos de internação hospitalar por taquicardia ventricular, e em verde internação para troca de gerador do cardioversor-desfibrilador automático. Abl: ablação; RAE: radioterapia ablativa esterotáxica.
Figure 1
Figure 1. – Radiation therapy planning. Ventricular tachycardia morphologies induced in the electrophysiological study (A) were analyzed, and the exit site was demarcated on the three-dimensional reconstruction of computed tomography scans and, once exit sites were demarcated, there was the definition of the area to be irradiated (B). The defined area was then manually demarcated in the radiation therapy system (C), which calculated dose constraints for each surrounding structure (D).
Figure 2
Figure 2. – Time line and column graph showing the number of therapies in each month (blue column before radiation therapy, green column after) and times of ablations (blue vertical line) and radiation therapy (red vertical line). Times of hospitalization due to ventricular tachycardia are shown in orange, and times of hospitalization for changing the implantable cardioverter defibrillator generator are shown in green. Abl: ablation; SBRT: stereotactic body radiation therapy.
