Abstract Background Good mid-term durability of mitral valve repair of bileaflet lesions has been reported; however, patients may develop failure during follow-up. This study assessed late outcomes and mechanisms of failure associated with mitral valve repair of bileaflet lesions. Methods Fifty-six patients (mean age 67 ± 12 years) underwent mitral valve repair of bileaflet lesions due to degenerative disease in 2011–2018. Mitral annuloplasty was added to all procedures except for 1 patient with annular calcification. Mitral valve lesions were identified by surgical inspection. Mean clinical and echocardiography follow-up occurred at 2.7 ± 2.1 and 2.5 ± 1.9 years, respectively. Results Additional mitral valve repair techniques involved triangular resection (n = 15 patients), quadrangular resection with sliding plasty (n = 12), neochordoplasty (n = 52), and commissural plication (n = 26). Prolapse of ≥2 anterior and posterior leaflet scallops occurred in 22 (39%) and 30 (54%) patients, respectively. During follow-up, 10 (17.8%) patients developed moderate or severe mitral regurgitation. Whereas prolapse or tethering was observed early after neochordoplasty or quadrangular resection, recurrent regurgitation occurred late after commissural repair. Five-year freedom from recurrent moderate or severe mitral regurgitation rates was 71.1 ± 11.0%. Conclusions Seventeen percent of patients developed recurrent mitral regurgitation during follow-up. Repair failure in the early phase occurred owing to aggressive resection of the posterior mitral leaflet or maladjustment of the artificial neochordae. Recurrent mitral regurgitation might occur in the late phase even after acceptable commissural repair. A sequential approach may be useful to improve the quality of mitral valve repair in bileaflet lesions.

Autologous Pericardium

Background and aim of the study. Wrapping of the ascending aorta (AA), isolated or associated with aortoplasty, has never been completely accepted. Some complications, as folding of the aortic wall, compression of the vasa vasorum and changes in the flow pattern, with consequent dilatation of the proximal arch, have been described. We used fresh autologous pericardium (FAP), so far never reported, to wrap the AA, with the aim to stabilize its size when moderately dilated, maintaining the preoperative dimension or limiting the reduction to a few mm. Material and Methods. From 2015 to 2019, 10 patients, who were operated on for valve or coronary surgery or both, underwent wrapping of the AA with FAP. Mean age was 69±7 years and ESII 3.5±1.7. Four patients had moderately impaired ejection fraction (35-49%). Results. There was no early or late mortality. One patient was reoperated on after 48 months for severe mitral regurgitation. At a follow up of 53±14 months, a transthoracic echocardiogram showed that the AA size reduced slightly but significantly, from 45.2±2.0 to 42.5±4.1 mm, p=0.03. The diameter of the proximal arch remained unchanged, from 37.1±1.6 to 36.3±2.9 mm, p=0.20. Conclusions. In presence of moderately dilated AA wrapping can be a reasonable option. The use of FAP stabilizes the size of the aorta after a follow up of 53 months. Maintaining a size similar to the preoperative one avoids the complications related to the procedure.

Abstract Background MitraClip implantation induces hemodynamic unloading and reverse remodeling of the left atrium (LA) and the left ventricle (LV). However little data exist concerning the effects of MitraClip implantation on LA and LV strain reflecting LA and LV function. Methods and results From August 2017 to September 2018 62 patients with moderate to severe mitral regurgitation were prospectively enrolled in our single-center RETORT-MR trial (Regensburg Trial on TMVR Techniques in Mitral Regurgitation). All included patients were treated using the MitraClip procedure. Two dimensional speckle tracking echocardiography (2DSTE) of the LA as well as of the LV could be performed in 35 patients with follow-up 2DSTE at four weeks and/or three months after MitraClip implantation. In 25.7% of patients primary mitral regurgitation was present (n=9) and in 74.3% of subjects a secondary entity of mitral regurgitation had been diagnosed (n=26). 57.1% of patients (n=20) suffered from heart failure with preserved ejection fraction (HFpEF) and 42.9% of patients (n=15) had heart failure with reduced ejection fraction (HFrEF). Global longitudinal strain (GLS) was reduced at baseline (−15.3%), at four-week (−14.5%, n=27) and at three-month follow-up (−13.9%, n=28) with no statistically significant differences indicating a sustained mechanical impairment of LV. In contrast significant deterioration was observed in the peak atrial longitudinal strain (PALS) representing LA reservoir function (15.3% at baseline vs. 11.8% at four-week follow-up, n=25, p=0.015 and 16.0% at baseline vs. 13.2% at three-month follow-up, n=25, p=0.03). Similarly to LA reservoir function LA booster function indicating left atrial active contraction was significantly reduced after MitraClip implantation (12.5% at baseline vs. 8.0% at four-week follow-up, n=10, p=0.028). Contrary to LA functional parameters LA size did not change significantly after MitraClip implantation (LA volume index at baseline 74.5 ml/m2 vs. 70.1 ml/m2 at four-week follow-up, n=27, p=0.489). Conclusion The present study revealed a deterioration of LA functional parameters (LA reservoir and LA booster function) after MitraClip insertion. It is known that severe mitral regurgitation can cause structural changes of the LA such as fibrosis. MitraClip insertion leads to a significant reduction of regurgitant volumes but structural changes of the LA may not be reversible. In addition MitraClip implantation increases afterload in the LA potentially explaining the observed deterioration of LA functional parameters. Acknowledgement/Funding None

Adult Onset Still's Disease

Abstract Background Adult-onset Still’s disease (AOSD) is an uncommon systemic inflammatory disease, causing spiking fever, skin rash, and arthritis. Pericarditis and myocarditis are the most common cardiac manifestation of AOSD but valvular involvement is rarely reported. Case summary An 18-year-old boy presented with gradually worsening shortness of breath for 6 months. There was a history of low-grade intermittent fever and polyarthralgia affecting ankles, knees, and elbows. He was in heart failure with cardiogenic and septic shock. He was managed initially with antibiotics, inotropes, and diuretics. Echocardiography showed flail anterior mitral leaflet with severe mitral regurgitation. He remained febrile with persistent negative blood cultures. Intravenous antibiotics led to neutropenia without any response to fever and clinical status. On further workup, he was diagnosed to have AOSD, and he responded dramatically to oral steroid therapy. Later his mitral valve was replaced surgically. On follow-up, he was stable with mild exertional dyspnoea. His international normalized ratio was in therapeutic range and his follow-up echocardiography showed normally functioning mitral prosthesis. He is following rheumatology and currently on the maintenance dose of steroids. Discussion Adult-onset Still’s disease is a systemic illness with diagnosis is based on clinical features and exclusion of other illnesses. Adult-onset Still’s disease should be considered as a differential diagnosis in culture-negative endocarditis, especially in those with systemic features and non-responders to antibiotics.
