Cor Triatriatum Sinister

Adult cor triatriatum sinister associated with severe mitral regurgitation is extremely rare. As these obstructive cor triatriatum feature hemodynamics that mimic mitral stenosis, a pressure load is theoretically generated only on the left atrial proximal chamber, and therefore the left ventricle is less likely to suffer volume loading. Here, we report a surgical case with such rare hemodynamics. A 22-year-old man with obstructive cor triatriatum and severe mitral regurgitation received an anomalous membrane excision and mitral annuloplasty. An abnormal membrane with an orifice 7 mm in size was completely resected while a grossly dilated mitral annulus was repaired via annuloplasty ring. Mitral regurgitation was controlled well, and the postoperative course was uneventful. Even with obstructive cor triatriatum, severe mitral annular dilatation and subsequent left ventricular dilatation may occur, causing the progressive heart failure encountered in this case.

AbstractA 38-year-old man was admitted to our department with moderate exertional dyspnea, fatigue and a syncope during exercise. The medical history revealed: left pulmonary sarcoma at the age of four, treated with radiotherapy, chemotherapy and left total pneumonectomy. At admission, laboratory tests showed high BNP (1426 pg/ml), normal calcium and parathormon levels. The transthoracic echocardiography found normal left ventricular (LV) systolic function with severe calcifications of the papillary muscles, mitral annulus, apical segments of the inferior septum and inferior wall (panel A - arrows; panel D) associated with severe mitral regurgitation (panel B). It also revealed severe tricuspid valve regurgitation, severe pulmonary hypertension (estimated to 120 mmHg, panel C) and small amount of pericardial fluid. A thoracic computed tomography described severe cardiac calcifications (panels E and F, arrow), a hypertrophic right lung herniated in left hemythorax and no other pathological findings in the remnant lung tissue. The pneumological evaluation noted a severe restrictive dysfunction. In this case, pulmonary hypertension was most probably determined by the left cardiac disorders (severe mitral regurgitation postradiotherapy, LV diastolic dysfunction due to severe myocardial and papillary muscle calcifications), most probably related to thoracic radiotherapy during childhood.

Abstract Introduction Mitral regurgitation is often found in conjunction with aortic stenosis and the prevalence of both valvular lesions increases with age. Purpose The aim of this study was to evaluate mitral regurgitation, left ventricle and left atrium in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI). Methods A total of 31 patients (29% males) with severe aortic stenosis and moderate or severe mitral regurgitation, who underwent TAVI were included in this study. Clinical and echocardiographic characteristics were performed at baseline and in 6, 12 months observation. Results After TAVI, decrease of vena contracta width of mitral regurgitation (p = 0.00002, p = 0.00004), aorto-mural mitral annulus diameter (p = 0.00008, p = 0.02), increase mitral annular plane systolic excursion (p = 0.0004, p = 0.0003), left ventricular stroke volume (p = 0.0003, p = 0.0004), ejection fraction (p = 0.0004, p = 0.01) and decrease major dimension of left ventricle in three chamber view (p = 0.05, p = 0.002) was observed in patient in both time points, respectively. Additionally, we observed decrease of distance between head of papillary muscles (p = 0.003) at 6 months and decrease of left atrium indexed volume (p = 0.01) and grade of tricuspid regurgitation (p = 0.03) at 12 months follow up. Conclusions Patients with moderate or severe mitral regurgitation after TAVI procedure achieved significant reductions of mitral regurgitation and improvement of some parameters assessing mitral annulus, left ventricle and left atrium geometry.

Anatomical Relationship

Functional mitral regurgitation affects a substantial proportion of patients with congestive heart failure due to myocardial infarction or dilated cardiomyopathy. Functional mitral regurgitation greatly increases morbidity and mortality. Surgical annuloplasty is the standard of care for symptomatic patients with moderate or severe functional mitral regurgitation; however, a large number of patients are refused surgery. Several percutaneous approaches have been developed to address the need for less invasive treatment of mitral annulus dilatation. Devices using coronary sinus to cinch the mitral annulus are relatively easy to use; however, a number of factors may limit their clinical application, such as suboptimal anatomical relationship between the coronary sinus and mitral annulus, risk of coronary artery compression, large variability in the coronary venous anatomy and conflict with other therapies such as ablation or cardiac resynchronisation. Direct mitral annuloplasty is anticipated to be more effective than the coronary sinus approaches; however, it has yet to prove its safety and efficacy in carefully designed clinical trials. The best candidates and the best timing for each percutaneous mitral annuloplasty therapy, whether direct or indirect, have yet to be identified.

Safety And Efficacy

Percutaneous treatment of severe mitral regurgitation is a very interesting therapeutic option for those patients considered not to be suitable candidates for surgery. Different technologies have already demonstrated proof-of-concept, and one of these devices (the Mitraclip device) has already obtained the Conformité Europeéne mark. However, demonstrating safety and efficacy for most of these technologies is being harder than anticipated. Recently, research and development has become more compromised due to the financial crisis. This paper reviews the venues that are currently under evaluation.
