Abstract Background Data on changes in left atrial (LA) and left ventricular (LV) volumes after transcatheter mitral valve replacement (TMVR) are limited. Purpose This study sought to describe the anatomical and functional changes in left-sided cardiac chambers by computed tomography angiography (CTA) from baseline to 1-month after TMVR with Tendyne prosthesis. Methods We analyzed patients who underwent TMVR with Tendyne prosthesis (Abbott Structural, Menlo Park, CA) between 2015 and 2018. Changes in LV end-diastolic volume (LVEDV), ejection fraction (LVEF), mass (LV mass), LA volume and global longitudinal strain (GLS) were assessed at baseline and at 1-month after TMVR with CTA. Specific Tendyne implant characteristics were identified and correlated with remodeling changes. Results A total of 36 patients (mean age 73±8 years, 78% men, 86% secondary MR) were studied. There were significant decreases in LVEDV (268±68 vs. 240±66ml, p<0.001), LVEF (38±10 vs. 32±11%, p<0.001), LV mass (126±37 vs. 117±32g, p<0.001), LA volume (181±74 vs. 174±70 ml, p=0.027) and GLS (−12.6±5.1 vs. −9.5±4.0%, p<0.001) from baseline to 1-month follow-up. Favorable LVEDV reverse-remodeling occurred in the majority (30 of 36 patients, or 83%). Closer proximity of the Tendyne apical pad to the true apex was predictive of favorable remodeling (pad distance: 25.0±7.7 vs. 33.5±8.8mm, p=0.02 for those with and without favorable remodeling). Conclusions TMVR with Tendyne results in favorable left-sided chamber remodeling in the majority of patients treated, as detected on CTA at 1-month after implantation. CTA identifies the favorable post-TMVR changes, which could be related to specific characteristics of the device implantation. Funding Acknowledgement Type of funding source: None

A trans-thoracic echocardiography and chest radiograph of a 26 year old lady diagnosed as rheumatic mitral regurgitation with atrial fibrillation revealed a giant left atrium of 10.9 cm size with symptoms of dyspnoea and palpitation. The patient was treated with left atrial size reduction along with mitral valve replacement surgery and showed an excellent and quick recovery with total disappearance of symptoms and restoration of sinus rhythm only within few days.University Heart Journal Vol. 14, No. 1, Jan 2018; 42-44

Background: Open mitral operation in patients with massive left atrial thrombus still with high mortality due to intra-operative embolism. To prevent this mortality due to intra-operative embolism and to prevent this danger we practiced a surgical technique which includes careful handling of heart and obliteration of left ventricular cavity by bilateral compression.Method: We used this technique in patients of severe mitral stenosis with atrial thrombus during mitral valve replacement. Our technique was to obliterate the left ventricular cavity and thus keep the mitral cusps in a coapted position by placing gauge posterior to left ventricle and a compression over right ventricle by hand of an assistant with a piece of gauze. This obliteration prevented passage of fragments of left atrial thrombus towards collapsed left ventricle.Result: Before practicing this technique, 4 out 9 patients expired due to cerebral embolism . But after implementation of this technique in 17 patients no mortality or morbidity occurred.Conclusion: This technique of removal of left atrial thrombus during mitral valve replacement may be a safe procedure for preventing peroperative embolism.Bangladesh Heart Journal 2016; 31(1) : 26-28
