Spontaneous Recanalized Chronic Total Occlusion or Recanalized Thrombus-What Are the Differentials?

The authors comment on certain points of the Akhar article from the April 2022 issue of the JIC. In their letter, they differentiate between chronic total occlusions and functional occlusions and discuss spontaneous recanalizations and the appearance of multiple intraluminal channels.They question whether the thrombotic occlusion of the right coronary artery was because of atherothrombosis or thromboembolism of both the right coronary artery and pulmonary circulation. The authors also mention that the index case needs a detailed evaluation of the hypercoagulable state to explain thrombosis of both the pulmonary and coronary circulation.
