Abstract Background Patients with ccTGA often develop tricuspid valve (systemic atrioventricular valve (AV) dysfunction due to RV overload and dilatation, but isolated mitral valve disease is rarely found. Isolated Mitral (subpulmonic AV -valve) interventions, specifically catheter-directed, have not been reported up to date. Case Summary A man with congenitally corrected transposition of the great arteries (ccTGA) is evaluated for dyspnoea. Multimodality imaging assessment confirmed severe right-sided mitral valve regurgitation due to prolapse. In light of high surgical risk, a minimally invasive transcatheter MitraClip procedure was pursued. Discussion To our knowledge, this is the first case of successful mitral valve repair via percutaneous approach using MitraClip in a patient with ccTGA and biventricular failure. Our case illustrates the safety and feasibility of the edge-to-edge procedure in such a rare instance, but also the importance of multimodality imaging (both invasive and non-invasive) and the Heart Team approach when caring for these complex patients.

SummaryAccessory atrioventricular valvar tissue is uncommon and, on occasion, has been identified as a cause of ventricular outflow obstruction. Accessory tricuspid valvar tissue has been reported to cause subpulmonary obstruction but infrequently has accessory tissue arising from the mitral valve been associated with obstruction. This paper reports two cases of subvalvar obstruction; the first in association with a ventricular septal defect causing subaortic obstruction and the other in association with congenitally corrected transposition and a ventricular septal defect, causing subpulmonary obstruction.

The prevalence of mitral regurgitation (MR) is increasing in Western countries, which results in making it the second most frequent valvular heart disease requiring surgery. MR can be classified as primary (organic) or secondary (functional). Causes of primary MR consist of leaflet lesions, either degenerative changes (Barlow’s disease, fibroelastic degeneration, and annular calcification), rheumatic disease, or infective endocarditis. Causes of secondary MR consist of those that produce geometrical distortion of the subvalvular apparatus due to dilatation and remodelling of the left ventricle such as ischaemic heart disease and cardiomyopathies. The implementation of mitral valve repair as well as the rise of new transcatheter techniques, provided that are performed in experienced, high volume centres with the contribution of a valvular heart team, have impressively changed the prognosis of patients with severe MR. This has set new frontiers in the management of MR and has upgraded the role of imaging, creating new responsibilities, since its presence in every step of the procedure either preoperatively (quantification of MR, determination of the underlying mechanisms, investigation of reparability, determination of prognosis) or intra- and postoperatively, has been declared as fundamental.

Abstract A 72-year-old female patient with a past medical history of severe mitral regurgitation, atrial fibrillation and embolic cerebrovascular events was admitted to our institution. The patient was under optimal medical therapy and complained for progressive worsening of activity-related dyspnea with limitation of physical activity (NYHA III). Transthoracic echocardiography showed the presence of severe mitral regurgitation with a central jet. There was prolapse of both mitral valve leaflets and interestingly the anterior leaflet presented systolic anterior motion (SAM) at the same time. There was no significant left ventricular outflow tract obstruction (LVOT). Further evaluation of the regurgitant mitral valve with a transesophageal echocardiography (TOE) confirmed the above findings and the mechanism of MV regurgitation was attributed to prolapse in addition to SAM of an elongated anterior leaflet. Laboratory test showed elevated NT-pro-BNP levels. A coronary angiography was performed and excluded significant coronary artery disease. The findings were assessed by our institution’s HEART TEAM and, in the presence of high surgical risk (LogEuroscore 32,76%), a decision for transcatheter mitral valve repair with a Mitral Clip implantation was taken. The Mitral Clip was succesfully implanted with immediate significant reduction of the regurgitant jet and no signs of stenotic behavior of the repaired valve. There was only mild mitral valve regurgitation. Notably, after the procedure there was elimination of the SAM and no LVOT obstruction (Figure). In accordance to the echocardiography findings, the patient demonstrated a significant clinical improvement and was discharged home 1 day after the procedure. Mitral clip implantation in this case showed improvement of the MR by reducing the SAM of the mitral valve. Abstract P1320 Figure.
