Background Cardiac involvement in sarcoidosis has been associated with poor prognosis. We evaluated myocardial contractility quantitatively in a cohort of pulmonary sarcoidosis (PS) patients with and without cardiac involvement. We also studied markers of fibrosis (tenascin-C [Tn-C] and galectin-3 [Gl-3]) as diagnostic tools for PS and cardiac sarcoidosis (CS). Methods Forty ambulatory patients with PS of grades 1-2 and 26 healthy subjects were prospectively enrolled. All patients with PS underwent cardiac magnetic resonance (CMR) to explore the presence of CS. The study population was divided into three groups: controls (n = 26), non-CS patients (n = 34), and CS patients (n = 6). Speckle-tracking strain echocardiography (STE) was performed on all patients, and Gl-3 and Tn-C values were measured in all patients and controls. Results PS patients had higher levels of Gl-3 and Tn-C than did controls, and the STE parameters of PS patients, including global longitudinal strain (GLS) and global circumferential strain (GCS), were lower than those of controls (p < 0.001 for all comparisons). GLS values were lower in CS patients than in the other groups (p = 0.05). Conclusions PS patients demonstrate reduced cardiac contractility, independent of CMR-proven structural cardiac lesions, while patients with structural lesions have a more pronounced drop in strain parameters. Tn-C and Gl-3 are promising markers for the diagnosis of PS, but they are not specific for cardiac involvement., Author(s): Seref Kul[sup.1] , Hatice Kutbay Ozcelik[sup.2] , Huseyin Uyarel[sup.1] , Gultekin Karakus[sup.3] , Tolga Sinan Guvenc[sup.4] , Murat Yalcinsoy[sup.5] , Emin Asoglu[sup.1] , Ahu Sarbay Kemik[sup.6] , Abdurrahman Tasal[sup.1] [...]

Combined therapeutic approach with performing mitral valve repair may be necessitated for the treatment of idiopathic hypertrophic subaortic stenosis (IHSS) with systolic anterior motion. This report includes operative technique for combined robotic septal myectomy and mitral valve repair. A 45-year-old man with IHSS was admitted to our center for surgical intervention. The transthoracic echocardiography showed typical asymmetric ventricular hypertrophy. Left ventricle posterior wall thickness was 11 mm, and interventricular septum thickness was 21 mm. Mitral valve leaflets were found to be elongated. Mild-to-severe mitral regurgitation was detected with eccentric mitral jet. Aortic peak gradient was 128 mm Hg. Robotic mitral repair and septal myectomy through left atrial exposure was performed. The anterior leaflet was detached, and the septal muscle in a mass of 1 × 0.7 × 0.5 cm was resected. Next, the anterior leaflet was reattached with continuous suture. The plication of the posterior leaflet with transverse incision was performed to diminish the length of posterior leaflet. After the magic suture for posteromedial commissure was performed, a 34 Medtronic Future ring was implanted for mitral annuloplasty. Postoperative course was uneventful. The patient was discharged on the sixth postoperative day. Combined robotic septal myectomy and mitral valve repair for IHSS with systolic anterior motion may be feasible.
