Diagnosis and management of spontaneously recanalized coronary thrombus guided by optical coherence tomography ― lessons from the French “Lotus Root” registry ―

Background: Spontaneous reanalyzed coronary thrombus (SRCT) has been reported in autopsy series, but little is known about SRCT, and it is potentially under-diagnosed in clinical practice. Methods and Results: SRCT identified on OCT were included in a French multicenter series, the Lotus Root French Registry. A total of 34 SRCT were identified on OCT in 33 patients (23 male; median age, 56 years; IQR, 52–65 years); 23/33 patients (70%) presented with angina pectoris and/or dyspnea. Three angiographic aspects were distinguished retrospectively: braided, pseudo-dissected, and hazy. Stenosis severity on quantitative coronary analysis varied between 11% and 100% (median, 45%), whereas the reduction in lumen area on OCT varied between 20% and 92% (median, 68%). A typical “lotus root” aspect was confirmed on OCT, consisting of multiple circular concave-edged channels of varying size, numbering between 3 and 12 depending on the slice, separated by smooth-edged septa of high luminosity without posterior attenuation. OCT also served to guide treatment, with stenting in 91% of cases. During the 17-month follow-up 91% of patients had excellent evolution. One death and 3 ACS events occurred. Conclusions: In this large SRCT cohort, angiography had limited diagnostic value whereas OCT could be used to define disease characteristics and guide treatment of lesions inducing angina pectoris and/or silent myocardial ischemia. OCT-guided management was associated with good prognosis
