Giant Left Atrium

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

Transcatheter Mitral Valve Replacement

Abstract Background Transcatheter mitral valve replacement (TMVR) is a challenging, but promising minimally invasive treatment option for patients with mitral valve disease. Depending on the anchoring mechanism, complications such as mitral leaflet or chordal disruption, aortic valve disruption or left ventricular outflow tract obstruction may occur. Supra-annular devices only anchor at the left atrial (LA) level with a low risk of these complications. For development of transcatheter valves based on LA anchoring, animal feasibility studies are required. In this study we sought to describe LA systolic and diastolic geometry in an ovine ischemic mitral regurgitation (IMR) model using magnetic resonance imaging (MRI) and echocardiography in order to facilitate future research focusing on TMVR device development for (I)MR with LA anchoring mechanisms. Methods A group of 10 adult male Dorsett sheep underwent a left lateral thoracotomy. Posterolateral myocardial infarction was created by ligation of the left circumflex coronary artery, the obtuse marginal and diagonal branches. MRI and echocardiography were performed at baseline and 8 weeks after myocardial infarction (MI). Results Six animals survived to 8 weeks follow-up. All animals had grade 2 + or higher IMR 8 weeks post-MI. All LA geometric parameters did not change significantly 8 weeks post-MI compared to baseline. Diastolic and systolic interpapillary muscle distance increased significantly 8 weeks post-MI. Conclusions Systolic and diastolic LA geometry do not change significantly in the presence of grade 2 + or higher IMR 8 weeks post-MI. These findings help facilitate future tailored TMVR device development with LA anchoring mechanisms.

Aims.To assess the outcomes of atrial fibrillation (AF) treatment by radiofrequency ablation for patients with mitral valve replacement, the analysis of short-term results of 128 patients was performed.Methods.Mean age of the patients was 56,7±9,6 (29 - 79) years, males - 39, females - 89. Most of the patients had longstanding persistent AF - 81 (63,3%), 28 (21,9%) had persistent AF and 19 (14,8%) - paroxysmal AF. The indications for surgery were: rheumatic mitral valve disease in 105 patients (82%), degerative mitral valve disease - in 21 (16,4%) and with treated infectious endocarditis - in 2 (1,6%). Maze IV procedure was carried out in all cases.Results.Hospital mortality was 0,8% (1 patient). Ten patients (7,9%) required pacemaker implantation. The indications were sinus node dysfunction in 7 patients, bradycardia AF - in 2 patients, AV node dysfunction - in 1. At the discharge 88 patients (69,3%) had a sinus rhythm, 10 (7,9%) - atrial rhythm, pacemaker rhythm with sinus node dysfunction patients - in 4 (3,1%) and AF - in 25 (19,7%). Thus, the rate of freedom from atrial fibrillation was 80,3% (102 patients). The effectiveness of ablation for paroxysmal AF was 100%, persistent - 74,1%, longstanding persistent - 77,8% (p=0,006). To reveal other predictors of freedom from AF at the discharge each ECHO parameter was included in the simple logistic regression analysis. Statistically significant p-value was obtained for the preoperative right atrial size (p=0,005), and close to it for the left atrial size, especially for the index left atrial volume/body surface area (p=0,052).Conclusion.Thus, the radiofrequency ablation is an effective method for treatment of AF in patients undergoing mitral valve replacement. The rate of freedom from AF at the discharge is 80,3%. The predictors of freedom from AF at the discharge are preoperative form of AF and preoperative size of atria.
