    Background: The prognosis of hypertrophic cardiomyopathy (HCM) varies from mild disease with a normal life expectancy to heart failure and sudden cardiac death (SCD). The identification of patients who are at high risk for SCD remains challenging. Aims: In this study, we evaluated the prognostic value of papillary muscle-free strain in HCM patients. Methods and Results: Seventy-nine patients with a diagnosis of HCM were included in this study. Patients were divided into low/intermediate-risk (n = 57) and high-risk (n = 22) groups. Two-dimensional (2-D) echocardiography and strain imaging were performed for each patient. The mean age of the study population was 53.85 +/- 15.88 years; 47 (59.5%) of them were male. During a mean follow-up duration of 74.45 +/- 17.03 months, 12 patients died. A comparison of the low-intermediate and high-SCD risk groups revealed that patients in the high-SCD risk group had greater maximal wall thickness, interventricular septum thickness, posterior wall thickness, and left ventricular mass index (LVMI) and lower (less negative) global longitudinal, anterolateral papillary muscle (ALPM) and posteromedial papillary muscle (PMPM) free strain. Additionally, a history of syncope and ICD implantation were found to be more common in patients with high SCD risk scores. The SCD risk score was positively correlated with the global longitudinal strain, ALPM-free strain, and PMPM-free strain (r = .528, r = .658, and r = .600, respectively; p < .001 for all). Our results showed that the LVMI, presence of syncope, global longitudinal strain, and ALPM-free strain were predictors of death. Conclusions: Decreased papillary muscle-free strain values might have prognostic value in patients with HCM.

    Persistent right heart dilatation after percutaneous mitral balloon valvuloplasty: A weird coexistence of iatrogenic and congenital shunts
    (John Wiley and Sons Inc, 2022) Güler, Arda; Topel, Çağdaş; Memiç Sancar, Kadriye; Kahveci, Gökhan; Onan, Burak; Güler, Gamze Babur
    We present an interesting case of concomitant congenital anomalies with an iatrogenic defect. The female patient underwent a percutaneous mitral balloon valvuloplasty due to rheumatic mitral stenosis. Unfortunately, an iatrogenic atrial septal defect (ASD) transpired during the procedure. Upon post-procedure examination, partial anomalous pulmonary venous (PAPVR) return was observed. The patient was symptomatic; on imaging, dilatation of the right heart chambers were detected. In addition, another crucial point was that the patient was planning a pregnancy, thus robotic surgery for iatrogenic ASD and PAPVR return was recommended. After a successful operation, the patient was asymptomatic and the size of right heart chambers were normalized. © 2022 Wiley Periodicals LLC.

    Right atrial reservoir strain and right ventricular strain improves in patients recovered from hospitalisation for non-severe COVID-19
    (NCI CPTAC Assay Portal, 2022) Sonsöz, Mehmet Rasih; Güven, Gülden; Yıldız, Ufuk; Koyuncu, Atilla; Altuntaş Aydın, Özlem; Kahveci, Gökhan
    Purpose: Those hospitalised with coronavirus disease 2019 (COVID-19) have recently been shown to have impaired right ventricular (RV) strain, but data about the course of heart function after discharge are limited. Our aim was to compare right ventricular strain and right atrial reservoir strain (RASr) associated with COVID-19 between acute disease (during hospitalisation) and follow-up (after discharge). Methods: In this retrospective single-center study, we analysed the echocardiograms of 43 patients hospitalised for non-severe COVID-19 between December 2020 and March 2021, undergoing echocardiography both during and after hospitalisation. In addition to conventional echocardiographic parameters, we applied 2-dimensional speckle tracking to obtain RV global longitudinal strain (RV-GLS), RV free wall strain (RV-FWS), and RASr. Results: Mean (standard deviation) age of the study population was 50 (9) years, and 18 (42%) of the participants were women. Median duration between exams was 6 months (range, 5-7 months). Both mean RV-GLS and mean RV-FWS significantly increased at follow-up (-20.8 [3.8] vs. -23.5 [2.8], p < 0.001 and -23.3 [4.2] vs. -28.2 [2.8], p < 0.001; respectively), and RASr significantly improved as well (-32.3 [6.6] vs. -41.9 [9.8], p < 0.001). Conclusion: In patients hospitalised for non-severe COVID-19 pneumonia, RV-GLS, RV-FWS, and RASr improved significantly between acute disease and 6 months after discharge.
