Pectus excavatum presents challenges in cardiac operations due to anatomical abnormalities and limited exposure. We report a case of a 58-year-old male with severe pectus excavatum and significant mitral regurgitation successfully treated with minimally invasive mitral valve repair. Preoperative imaging revealed leftward heart displacement and a Haller index of 3.8. Surgical intervention involved adaptations in atrial retraction and valve repair technique. Postoperative outcomes were favourable, with normal mitral function and a short hospital stay. Despite technical challenges, minimally invasive approaches offer benefits in pectus excavatum patients. This case underscores the feasibility and safety of minimally invasive surgery in patients with extensive pectus excavatum, emphasizing its potential as a preferred approach.

UNASSIGNED: Systemic sclerosis presents with a variety of cardiac manifestations, while myocarditis is usually a rare finding. Furthermore, there are no reports on the use of mitral transcatheter edge-to-edge repair (M-TEER) for the treatment of severe ventricular functional mitral regurgitation (vFMR) secondary to scleroderma myocarditis.
UNASSIGNED: A-79-year-old male was admitted to our hospital because of fever and fatigue. His physical examination revealed thickening of the fingertips\' skin, Raynaud phenomenon, and mild pedal oedema. Positive anti-centromere antibodies indicated a diagnosis of a limited cutaneous systemic sclerosis. He presented with symptoms of heart failure, and moderate to severe lymphocytic infiltration was evident in his endomyocardial biopsy. He responded well to medical therapy and was discharged. However, one month after hospital discharge, he was readmitted to our institution because of worsening heart failure. Transthoracic echocardiography showed a decrease in left ventricular systolic function and progression of left ventricular remodelling, which caused severe vFMR. Endomyocardial biopsy revealed decreased lymphocytic infiltration and mild myocardial interstitial fibrosis, indicative of scleroderma myocarditis. As he was unable to be weaned off inotropes, we performed M-TEER for severe vFMR, which led to a significant reduction in MR volume and improvement of heart failure symptoms. A week after procedure, immunosuppressive therapy was initiated and the patient was discharged home in stable condition.
UNASSIGNED: Scleroderma myocarditis may manifest as heart failure with reduced ejection fraction with severe vFMR. Mitral transcatheter edge-to-edge repair for severe vFMR in the context of myocarditis can be one of the therapeutic options for haemodynamic stabilization.

UNASSIGNED: Arrhythmic mitral valve prolapse syndrome (ARMV) is a recognized but underdiagnosed disease pattern. Risk factors for ARMV are established but not very well known, and the association of the structural abnormality with ventricular arrhythmias is incompletely understood.
UNASSIGNED: Here, we present the case of a young man who presented at our hospital for radiofrequency catheter ablation and mitral valve surgery after two episodes of survived sudden cardiac arrest. We discuss the diagnostic and therapeutic strategies that were used. We shine light on the risk factors for ARMV and why early identification is crucial. We address the topic of primary prevention and its limitations. Finally, we discuss different treatment modalities for patients with ARMV.
UNASSIGNED: More awareness for ARMV is crucial. A consensus statement on clinical management exists, but scientific gaps in prospective data for primary prevention need to be filled and there is a need for a better understanding of the pathogenesis of ARMV.

UNASSIGNED: Thyrotoxicosis is related to cardiovascular mortality. This can be caused by several clinical manifestations involving the rare provocation of tricuspid regurgitation (TR) and mitral regurgitation (MR). However, there are still no clear data on thyrotoxic TR and/or MR. This study examines the progression of TR, MR, heart failure (HF) and pulmonary hypertension (PH) in response to the thyrotoxic heart manifestations, clinical characteristics and treatment approaches.
UNASSIGNED: A PRISMA-based systematic search was conducted using PubMed and other databases up to 17 June 2023. The outcomes of this study were TR, MR, HF and PH with their progression on follow-up, clinical characteristics and treatment approaches.
UNASSIGNED: A total of 57 case reports involving 62 patients (45.77 ± 13.41 years) were included in this study. They were predominantly women (n=50; 80.65%) and diagnosed with Graves\' disease (n=41; 75.81%). All patients were diagnosed with thyrotoxicosis, and this included 23 (37.10%) cases of thyroid storm. From echocardiographic studies, several patients improved clinically within the first 6 months of follow-up, including 20 TR patients (83.33%) in 6 months, nine MR patients (69.23%) in 3 months, eight HF patients (66.67%) in 2 months and 16 PH patients (76.19%) in 6 months.
UNASSIGNED: Several mechanisms are involved in thyrotoxic TR and/or MR, including the direct thyroid hormone effect and the indirect effect of other hyperthyroidism-associated factors. Patients with thyrotoxic TR and/or MR, including those with HF and PH, can experience clinical and structural improvements following hyperthyroidism treatment in the first 6 months.

UNASSIGNED: Transcatheter edge-to-edge mitral valve repair is now available in many countries and has achieved favourable therapeutic outcomes. However, there have been no reported cases of clip opening while locked (COWL) during the acute phase using the MitraClip G4 system (Abbott, Abbott Park, IL, USA).
UNASSIGNED: We present two cases of COWL occurring at different phases: one immediately after clip release and the other 2 days post-procedure. In both cases, the initial treatment involved the use of the XTW system. Subsequently, an additional XT system was deployed for the deterioration of mitral regurgitation caused by COWL, without any complications.
UNASSIGNED: The MitraClip G4 system offers four size variations, providing a larger grasping area and increased flexibility for accessing complex lesions. Furthermore, the complication rate decreased with increasing operator experience and device generation. However, it has been reported that COWL can occur after the clip is deployed during TEER. Although the mechanism of COWL is unclear, the nature and mobility of the valve leaflets and the product specificity of the MitraClip may be involved.

Remimazolam is a short-acting benzodiazepine sedative with a short half-life and little circulatory depression. The safe use of remimazolam in the anesthetic management of an elderly patient with impaired cardiac function is reported. The patient\'s hemodynamics remained stable, and the patient was managed without serious complications. Remimazolam may be an option for sedation in elderly patients with reduced cardiac function.

Infective endocarditis (IE) is a life-threatening cardiac infection usually associated with cardiac valves. Left atrial (LA) mural endocarditis is rarely seen and occurs in isolation or in conjunction with mitral valve endocarditis. We present a case of a 61-year-old male with no prior cardiac history who presented with melena and fevers. Blood cultures were positive for Enterococcus faecalis. Transesophageal echocardiogram (TEE) demonstrated aortic and mitral valve vegetations with several small echo densities present on the left atrial wall. These findings were further assessed with a computed tomography angiogram of the heart and cardiac magnetic resonance imaging Ti600 sequence. The patient was treated with intravenous antibiotics and underwent aortic and mitral valve replacement with resection of numerous small fungating masses on the left atrium. There are currently no formal guidelines in place for managing mural endocarditis. However, conducting a multidisciplinary evaluation by an endocarditis team could aid in achieving earlier and more precise diagnoses of the underlying condition and its complications. This approach could also ensure consistent antibiotic therapy and appropriate timing for surgical intervention.

We present a case report of a patient with infective endocarditis. He came to the emergency room with respiratory failure due to severe pneumonia and pulmonary edema. On 2D transesophageal echocardiography, vegetations were seen in both mitral and aortic valves, with mitral valve perforation and severe regurgitation. His clinical presentation and severity of the disease made him suitable for urgent valve repair. He was submitted to mitral valvuloplasty with closure of the valve perforation and insertion of a bioprosthetic aortic valve. Despite significant clinical improvement, a post-surgical complication was noted with new-onset lung injury after cardiopulmonary bypass. This is an interesting case of a patient with suspected retrograde valve involvement, affecting the aortic valve, the mitral-aortic intervalvular fibrosa, and the mitral valve, ending with mitral valve abscess with leaflet perforation and valvular regurgitation.
