We herein report a case of acute myocarditis possibly related to the second dose of an mRNA-coronavirus disease 2019 vaccine in a 45-year-old woman with no remarkable medical history. She had a fever for one week following the second dose of the mRNA-1273 severe acute respiratory syndrome coronavirus 2 vaccine. One week later, she presented with chest pain and electrocardiogram changes. Her serum troponin levels were elevated upon admission. Echocardiography showed segmental wall motion abnormalities of the apex, apical portion of the anterior and inferior walls. The findings of cardiac magnetic resonance imaging were consistent with acute myocarditis.

Background: Transcatheter mitral valve repair with the MitraClip system has been established in selected high-risk patients. The MitraClip procedure results in a relatively large iatrogenic atrial septal defect (iASD). This study aimed to investigate the prevalence and clinical course of iASD requiring transcatheter closure following the MitraClip procedure.Methods and Results: This study was conducted at all 59 institutions that perform transcatheter mitral valve repair with the MitraClip system in Japan. The data of patients on whom transcatheter iASD closure was performed were collected. Of the 2,722 patients who underwent the MitraClip procedure, 30 (1%) required transcatheter iASD closure. The maximum iASD size was 9±4 mm (range, 3–18 mm). The common clinical course of transcatheter iASD closure was hypoxemia with right-to-left shunt or right-sided heart failure with left-to-right shunt. Of the 30 patients, 22 (73%) required transcatheter closure within 24 h following the MitraClip procedure, including 12 with hypoxemia and 5 with right-sided heart failure complicated with cardiogenic shock. Of the 5 patients, 2 required mechanical circulatory support devices. Twenty-one patients immediately underwent transcatheter iASD closure, and hemodynamic deteriorations were resolved; however, 1 patient died without having undergone transcatheter closure.Conclusions: Transcatheter iASD closure was required in 1% of patients who underwent the MitraClip procedure. Many of these patients immediately underwent transcatheter iASD closure because of hypoxemia with right-to-left shunt or right-sided heart failure with left-to-right shunt.

Achilles tendon xanthoma (ATX) is one of the typical features of familial hypercholesterolemia (FH). The morphological evaluation of ATX by X-ray radiography is widely recognized; however, the utility of other imaging modalities remains unclear. We herein report two cases of FH in which Doppler ultrasound imaging demonstrated a microvascular flow in ATX that only rarely could be observed in normal Achilles tendons. Neoangiogenesis accompanies chronic inflammation and it may play an important role in the deposition of cholesterol crystals leading to ATX. In addition to the morphological evaluation of ATX, the assessment of neoangiogenesis may therefore be essential for the evaluation of ATX.
