Abstract Background Infective endocarditis can present without evident vegetation, diagnosis is challenging and prognosis very poor. We present an illustrative case where natural evolution of the mitral valve destruction with no evident vegetations was followed with frequent consecutive transthoracic (TTE) and transesophageal echocardiography (TOE). Case presentation 71-year old male with known dilated cardiomyopathy presented with dyspnoea, ankle swelling and severe kidney failure with hyperkalemia. During short hospitalization he was recompensated with haemodialysis, parenteral diuretics and inotropes. TTE showed dilated left ventricle with severe systolic dysfunction and no evidence of valvular disease. Few days after discharge he was readmitted with malaise and febrile state with no obvious site of infection. Blood cultures were positive for Staphylococcus aureus and antibiotic therapy was initiated immediately. Weekly TTEs and TOEs were performed (Figure 1, column A-D): Week 1: TTE was performed due to congestive heart failure. There was no suspicion on disease and TTE showed no obvious mitral valve pathology. Week 3: Second TTE showed only light thickening of posterior mitral leaflet with mild mitral regurgitation. Week 4: Follow-up TOE was performed showing posterior leaflet discontinuity with small eccentric regurgitation jet and no vegetation. Week 6: Symptoms of congestive heart failure persisted despite antibiotic treatment. A progressive destruction of posterior leaflet with evident perforation of P1 scallop and consequent severe mitral regurgitation. Patient was referred for urgent mitral valve replacement. Conclusions Staphylococcus aureus is a destructive pathogen and can cause severe destruction of native valve even without obvious vegetations. This case presents echocardiographic features of natural course of infective endocarditis on mitral valve. Despite antibiotic therapy progressive valve destruction is possible. Abstract P627 Figure.

Mitral valve leaflet aneurysm is a rare and potentially devastating complication of aortic valve endocarditis. We report the case of a 48-year-old man who had endocarditis of the native aortic valve and a concomitant aneurysm of the anterior mitral valve leaflet. Severe mitral regurgitation occurred after the aneurysm perforated. The patient showed no signs of heart failure and completed a 6-week regimen of antibiotic therapy before undergoing successful aortic and mitral valve replacement. In addition to the patient's case, we review the relevant medical literature.

During pregnancy, infective endocarditis (IE) is quite rare but has a high mortality rate in terms of the mother and the fetus. In this article, a 24-year-old patient with a history of mitral valve prolapse (MVP) who was hospitalized due to IE and treated successfully is presented. On echocardiography, severe mitral valve prolapse, severe mitral regurgitation, and vegetation on the posterior leaflet of mitral valve were observed. Streptococcus mitis was subsequently isolated from four sets of blood cultures. The patient was diagnosed with IE. After 6 weeks of antibiotic therapy, the patient was cured completely without surgical treatment. At 40-weeks of pregnancy, the patient gave birth via a normal vaginal delivery. There were no problems with the 3,800-gram baby born. In current guidelines, there is very limited advice on treatment options for patients who develop IE during pregnancy. Therefore, evaluation of patient-based treatment options would be appropriate. In addition, IE prophylaxis for MVP is not recommended in current guidelines. However, in MVP patients with mitral regurgitation, prior to procedures associated with a high risk of infective endocarditis, IE prophylaxis may be rational.

Abstract Funding Acknowledgements Type of funding sources: None. Purpose Cardiac resynchronization therapy (CRT) has  a positive effect on the improvement of functional mitral regurgitation in patients with low ejection heart failure. However geometric changes in the mitral valve apparatus, subvalvular structures and their contribution to  the improvement of mitral regurgitation after CRT have not  been clearly defined. The aim of our study was to evaluate the geometric parameters of mitral valve apparatus measured with 3Dimensional (3D) transesophageal echocardiography (TEE) before CRT implantation and to determine the parameters predicting the improvement of mitral regurgitation after CRT. Methods Thirty patients with moderate or severe mitral regurgitation with low EF heart failure planned for CRT implantation and had an indication for TEE were included in the study. Effective regurgitant orifice (ERO) and regurgitant volume (RV) measurements were performed before CRT implantation. Detailed quantitative measurements of mitral valve were done from recorded images by 3D TEE. ERO, RV measurements were repeated to evaluate mitral regurgitation at the end of 3rd month. Results There were no significant changes in left ventricular EF and left ventricular diameters at the end of 3rd month, whereas ERO and RV values were decreased. A statistically significant difference was found in  posterior leaflet angle between mitral regurgitation responder and non-responder groups.  (28,93 ± 8,41 vs 41,25 ± 10,90, p = 0,006). Conclusion Heart failure patients with moderate or severe functional mitral regurgitation who underwent CRT implantation were found to have lower posterior leaflet angle measured by 3D TEE in the patient group whose mitral regurgitation improved after CRT.

SummaryA 21-day-old girl presented with congestive heart failure of acute onset and Doppler evidence of mitral regurgitation, which subsequently proved fatal. Necropsy revealed an anomalous arcade lesion of the mitral valve. The tendinous cords of the tricuspid valve were also abnormal, a finding, to the best of our knowledge, not reported before.

Purpose: Cardiac resynchronization therapy (CRT) has a positive effect on the improvement of functional mitral regurgitation in patients with heart failure with reduced ejection fraction. However geometric changes in the mitral valve apparatus, subvalvular structures and their contribution to the improvement of mitral regurgitation after CRT have not been clearly defined. The aim of our study was to evaluate the geometric parameters of mitral valve apparatus measured with 3Dimensional (3D) transesophageal echocardiography (TEE) before CRT implantation and to determine the parameters predicting the improvement of mitral regurgitation after CRT. Methods: In this prospective study thirty patients with moderate or severe mitral regurgitation with low EF heart failure planned for CRT implantation and had an indication for TEE were included. Effective regurgitant orifice (ERO) and regurgitant volume (RV) measurements were performed before CRT implantation. Detailed quantitative measurements of mitral valve were done from recorded images by 3D TEE. ERO, RV measurements were repeated to evaluate mitral regurgitation at the end of 3rd month. Results: There were no significant changes in left ventricular EF and left ventricular diameters at third month follow-up, whereas ERO and RV values were decreased. posterior leaflet angle was found higher in non-responder group compared to responder group. (28,93 ± 8,41 vs 41,25 ± 10,90, p = 0,006). Conclusion: Heart failure patients with moderate or severe functional mitral regurgitation who underwent CRT implantation were found lower posterior leaflet angle which was measured by 3D TEE in the patient group whose mitral regurgitation improved after CRT.

The mitral valve prolapse is characterized by the degeneration of the valve leaflets, accompanied by their thickening, increasing surface area and flexibility. The mitral valves leaflets bulge (prolapse) beyond the plane of the atrioventricular ring into the left atrium during ventricular systole and lose the ability to close tightly, leading to the mitral regurgitation. Acute chord rupture of the mitral valve posterior leaflet is a rare but important cause of severe mitral regurgitation and the development of acute or progressive chronic heart failure. Acute mitral insufficiency, accompanied by hemodynamic disorders, requires an urgent valve plastic surgery or valve prosthetics. The mitral valve plastic surgery gives a number of undeniable advantages over prosthetics, providing the best hemodynamic parameters, saving the patient from lifelong receiving of anticoagulant drugs. Detailed qualified echocardiographic evaluation of all structures of the mitral valve (fibrous ring, MV leaflets by segments, overlapping structures, structure of the chordal apparatus, papillary muscles) provides the necessary information for the mitral valve reconstructive plastic surgery with the choice of the method that is most optimal for a certain patient at the preoperative stage. We report herein a clinical observation of the patient with a diagnosis: acquired heart disease, the mitral valve posterior leaflet prolapse with mitral insufficiency Grade 3. Chronic heart failure IIA. II FC. Atrial fibrillation. The patient underwent multicomponent mitral valve reconstruction with the creation of a neochord and the fibrous ring plastic on the duplicate of a PTFE strip (soft support ring), pairwise isolation of the pulmonary vein entrance and right cavotricuspid isthmus.

Abstract Patient Presentation and initial work up A 72 years old man with history of hypertension was admitted to our hospital due to acute pulmonary oedema. He had no fever at that time and he had an history of known mitral valve prolapse but with no reported mitral valve regurgitation (MR). Transthoracic Echocardiogram (TTE) was performed and it showed a severe MR. Transesophageal echocardiogram (TOE) showed prolapse of the posterior leaflet of the mitral valve with suspicion of cordal rupture and the presence of an aneurysm of the anterior mitral valve leaflet with perforation of it (panel A and B). Diagnosis and Management Diagnosis of severe MR as the result of previous endocarditis was made. Blood cultures were negative, as well as there were no signs of active endocarditis. However, since there were heart failure and signs of uncontrolled infection, the patient underwent surgical mitral valve replacement (MVR) with bioprosthesis. Moreover, it was started antibiotic therapy with vancomycin, rifampin and ceftriaxone, which was continued for two weeks and then stopped since the microbiological culture of the valve was negative. Follow-up After two months he was re-admitted to the hospital due to a new onset of breathlessness. TTE showed a dehiscence of the mitral prosthetic valve in the inferolateral zone with rocking movement, subvalvular pseudoaneurysm and moderate paravalvular leak (panel C and D). Blood cultures were positive for Staphylococcus Aureus. Consequently, the patient underwent a new surgical MVR. Furthermore, six weeks of antibiotic therapy were carried out with daptomycin and rifampin. However, after another three months, he was admitted once again to the hospital for heart failure with a new evidence of abruption of the mitral prosthesis, again in the inferolateral region and, this time, with the evidence of a vegetation on the atrial side of the prosthesis (panel E and F). Again, blood cultures were positive for Staphylococcus Aureus, and the patient underwent the third surgical intervention of MVR. Another six weeks of antibiotic therapy with daptomycin and rifampin were performed. The patient was then discharged and he is now strictly followed clinically. Conclusion In conclusion, we reported the case of a recurrent relapse of endocarditis on mitral valve prosthesis due to Staphylococcus Aureus infection. Interestingly, the mitral prosthesis was involved always in the same zone (inferolateral area) with abruption of the prosthesis and significant paravalvular regurgitation. At the second relapse there was also a vegetation on it and both times blood cultures were positive. Moreover, antibiotic therapy was conducted for six weeks both times, but the recurrence of endocarditis showed us that he was a sensitive patient and that in cases of relapses like this it should be performed a more careful clinical follow up, involving frequent laboratory tests and clinical and echocardiographic evaluations.
