Interesting. The ECV increased 1.1% (25 min) to 2.2% (5 min), which is difficult to explain. But it explains why LGE was less; it was quantified as the amount of myocardium 6SD brighter than "remote". LGE amount will be less if the remote myocardium is brighter after mavacamten than at baseline.

In patients with suspected cardiac sarcoidosis, CMR phenotyping showed greater discriminative accuracy than societal recommendations for predicting fatal or life-threatening ventricular arrhythmias, suggesting that it may be more effective at identifying candidates for primary prevention ICDs.

A new study in EHJ - Cardiovascular Imaging describes 324 patients with normal CMR and no high-risk features who all also had FDG-PET.

21.3% had FDG uptake.

Their annualized event rate was <1%, indicating that FDG-PET has little diagnostic or prognostic utility.

In patients with suspected cardiac sarcoidosis, cardiac FDG-PET is recommended after a normal CMR if there is a high clinical suspicion. What are the data supporting this recommendation? #CardioSky #MedSky #Sarcoidosis

Examples of study patients with serial CMR images. Patient A had resolution of LV thrombus on the first serial CMR done 64 days after the index CMR, and no recurrence was noted on subsequent serial CMRs done 688 and 1043 days after the index CMR. Patient B had no resolution of LV thrombus on serial CMRs done 591, 966, and 3555 days after the index CMR. Patient C had resolution of LV thrombus on the first serial CMR done 86 days after the index CMR; however, a new LV thrombus was identified on the second serial CMR done 401 days after the index CMR, which had resolved again by the third serial CMR done 1336 days after the index CMR.

Reproduced with permission from Greulich et al. (B) A patient with cardiomyopathy and likely pathogenic variants in the desmin (DES) and transforming growth factor β 3 (TGFB3) genes. (C) A patient with cardiomyopathy and a pathogenic variant in the desmoplakin (DSP) gene. (D) A patient with cardiomyopathy and a pathogenic variant in the filamin C (FLNC) gene. (E) A patient with cardiomyopathy and a pathogenic variant in the lamin A/C (LMNA) gene. (F) A patient with cardiomyopathy and a pathogenic variant in the titin (TTN) gene.

In a longitudinal study of 107 LV thrombus patients with >1 serial CMR (213 total CMRs), we found that resolution rates were only 25% at 3 months, 47% at 6 months, and 63% at 12 months!

We recently published this paper led by the talented @paragbawaskar.bsky.social

In 2019, we wrote a paper showing that patients with left ventricular thrombus have a long-term risk of embolism, extending to at least 8 years.

We were puzzled by the finding…

Figure 2 from the paper. Incidence of embolism in left ventricular (LV) thrombus patients compared with matched non-LV thrombus patients. Kaplan-Meier curves demonstrate the cumulative incidence of the composite embolic end point in the LV thrombus (in red) and in the matched non-LV thrombus (in blue) groups. Note the significant difference in the cumulative incidence of embolic events between the 2 groups.
