    Aim: The aim of this study was to investigate the predictive role of spontaneous echo contrast (SEC) in mitral restenosis after percutaneous balloon mitral valvuloplasty (PBMV). Material and Methods: We retrospectively analyzed 341 consecutive patients who underwent PBMV at our hospital. Subjects who participated in the study were assigned to two groups: patients who had demonstrable SEC in the left atrial cavity and left atrial appendage and patients who did not have SEC in the left atrial cavity and left atrial appendage. For each group, the following variables were analyzed: demographic characteristics, past medical records, laboratory values, transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) parameters. Results: Compared to patients without SEC, patients with SEC were older, had a higher incidence of diabetes mellitus (DM), ischemic stroke and AF (p<0.05). With respect to TTE and TEE measurements, patients with SEC had lower estimated pre-procedural left ventricular ejection fraction (LVEF), a smaller calculated mitral valve area (MVA), a larger left atrial (LA) dimension and higher estimated preprocedural Wilkins score (p<0.05). In addition, the incidence of mitral restenosis following PBMV was significantly higher in patients with SEC compared to patients without SEC ( p <0.05), and this difference was more apparent in patients with grade 3-4 SEC compared to those with grade 1-2 SEC (p<0.05) Discussion: Our data showed that there is a strong association between SEC formation in the left atrium and left atrial appendage and mitral restenosis following PBMV

    Role of cardiac magnetic resonance imaging in predicting atrial fibrillation in patients with hypertrophic cardiomyopathy
    (CUKUROVA UNIV, 2022) Güler, Arda; Şahin, Ahmet Anıl; Uçar, Servet Umut; Aydın, Sinem; Uygur, Begüm; Çelik, Ömer; Ertürk, Mehmet
    Purpose: The present study sought to investigate the association between Cardiac magnetic resonance (CMR) imaging parameters including late gadolinium enhancement (LGE), total left ventricular mass (TLVM), mitral regurgitation, and left atrial (LA) volume, with atrial fibrillation (AF) in hypertrophic cardiomyopathy (HCM). patients. Materials and Methods: Consecutive 122 patients with the diagnosis of HCM and together with having 48-hour Holter monitoring were included in the present work. Two experienced observers evaluated all CMR images. The correlation between AF and CMR parameters including TLVM, LA volume, the presence and extent of LGE, mitral regurgitation, and the maximum left ventricular thickness were evaluated. Results: Between the LA volume and AF, a significant correlation was observed. Additionally, TLVM was also associated with AF. The logistic multivariate analysis assessing TLVM, LA volume, and the extent of LGE revealed that only the left atrial volume was the independent predictor. Significant correlations were observed between the existence and extent of LGE, TLVM, mitral regurgitation and LA volume. Conclusion: The presence of LGE was positively correlated with LA volume. LA volume appears to be the most important independent predictor of AF in HCM patients.
