Ischemic mitral

Both transcatheter edge-to-edge repair (TEER) of mitral regurgitation or left atrial appendage closure (LAAC) require periprocedural anticoagulation with unfractionated heparin (UFH) that is administered either before or immediately after transseptal puncture (TSP). The optimal timing of UFH administration (before or after TSP) is unknown. The Strategy To Optimize PeriproCeduraL AnticOagulation in Structural Transseptal Interventions trial (STOP CLOT Trial) was designed to determine if early anticoagulation is effective in reducing ischemic complications without increasing the risk of periprocedural bleeding...

BACKGROUND: With the advances in percutaneous treatment technologies, the left atrial appendage occlusion (LAAO) and the transcatheter mitral valve repair using MitraClip (TMVR) are increasingly being performed today. The SAFARI 2™ guidewire is primarily used during transcatheter aortic valve implantation (TAVI), our group has also been using it during MitraClip and LAAO procedures. Our clinical study aimed to share our data on the safety and effectiveness for the use of the SAFARI 2™ guidewire during MitraClip or LAAO procedures...

INTRODUCTION: Presenting symptoms of atrial myxoma are classically viewed as a triad of cardiac, embolic, and constitutional symptoms. Dermatologic manifestations are viewed as constitutional symptoms and have not received much attention. METHODS: Illustrative case presentation and literature review. RESULTS: I admitted a 28 y woman transferred to the comprehensive stroke center with an ischemic stroke treated with intravenous thrombolysis...

We report a case of a 35 years old lady presenting with acute upper limb ischemia secondary to systemic lupus erythematosus (SLE), antiphospholipid syndrome (APLS) and infective endocarditis (IE). It is rare for SLE/APLS to present with acute limb ischemia (ALI) as the initial manifestation. The patient presented with high grade fever along with pain and numbness in her right upper limb. On examination her right upper limb was cold to touch and the peripheral pulses were not palpable. There was also an audible pansystolic murmur in the mitral area...

OBJECTIVE: Evidence supports replacement over repair for ischemic mitral regurgitation due to improved durability; however, the latter often involves an undersized ring annuloplasty that does not include edge-to-edge approximation. The objective of this study was to evaluate the outcomes of replacement, edge-to-edge leaflet approximation with mild-undersized annuloplasty and undersized ring annuloplasty for ischemic mitral regurgitation. METHODS: This is a single-center retrospective study of patients undergoing mitral surgery for moderate-severe or greater ischemic mitral regurgitation, between 2004 and 2020, with mild-undersized annuloplasty, mitral valve replacement, or undersized restrictive annuloplasty (undersized ring annuloplasty)...

OBJECTIVES: To describe outcomes of reconstruction of the aortomitral continuity (AMC) during concomitant aortic and mitral valve replacement (ie, the "Commando" procedure). DESIGN: A retrospective study of consecutive cardiac surgeries from 2010 to 2022. SETTING: At a single institution. PARTICIPANTS: All patients undergoing double aortic and mitral valve replacement. INTERVENTIONS: Patients were dichotomized by the performance (or not) of AMC reconstruction...

BACKGROUND: Owing to challenges associated with heart failure and cardiac embolism, infectious endocarditis emerges as a critical pathology characterized by elevated mortality and morbidity rates. Our case stands out as a rare instance of endocarditis involving multisystem embolization, with a successful outcome. CASE PRESENTATION: We present the case of an 81-year-old man whose admission was further complicated by various septic emboli affecting the brain (manifesting as a brain abscess and ischemic stroke), spleen (resulting in splenic infarction), and spinal cord...

BACKGROUND: We investigated the efficacy of left ventricular (LV) myocardial damage by native T1 mapping obtained with cardiac magnetic resonance (CMR) for patients undergoing transcatheter edge-to-edge repair (TEER).Methods and Results: We studied 40 symptomatic non-ischemic heart failure (HF) patients and ventricular functional mitral regurgitation (VFMR) undergoing TEER. LV myocardial damage was defined as the native T1 Z-score, which was converted from native T1 values obtained with CMR...

BACKGROUND: We compared total arterial revascularization (TAR) versus conventional revascularization (CR) in terms of left ventricular function recovery in patients with multivessel coronary artery disease (CAD) and reduced left ventricular ejection fraction (LVEF). METHODS: We conducted a retrospective cohort study of 162 consecutive patients with multivessel CAD and reduced LVEF who underwent isolated coronary artery bypass grafting at our institution between January 2013 and July 2022...

BACKGROUND: When mitral valve (MV) surgery is indicated, repair is preferred over replacement; however, this preference is not supported by evidence from clinical trials. Furthermore, the benefits of MV repair may not be universal for all etiologies of MV disease.Methods and Results: This study identified a total of 18,428 patients who underwent MV repair (n=4,817) or MV replacement (n=13,611) during 2001-2018 from Taiwan's National Health Insurance Research Database. These patients were classified into 4 etiologies: infective endocarditis (IE, n=2,678), rheumatic heart disease (RHD, n=4,524), ischemic mitral regurgitation (IMR, n=3,893), and degenerative mitral regurgitation (DMR, n=7,333)...

BACKGROUND: This case report highlights the rare association among a dental procedure, infective endocarditis, and an acute ischemic stroke. CASE DESCRIPTION: A 54-year-old woman who experienced an acute ischemic stroke 5 weeks after a tooth extraction is described. The initial symptoms of this patient included mild to moderate word-finding difficulty and right facial droop. Computed tomographic angiography revealed a left M1 segment middle cerebral artery occlusion (thrombolysis in cerebral infarction scale, 0) with reconstitution of the distal middle cerebral branches through arterial collaterals...

BACKGROUND: Mitral valve (MV) disease is the most common form of valvular heart disease. Findings that indicate women have a higher risk for unfavorable outcomes than men remain controversial. This study aimed to determine the sex-based differences in epidemiological distributions and outcomes of surgery for MV disease.Methods and Results: Overall, 18,572 patients (45.3% women) who underwent MV surgery between 2001 and 2018 were included. Outcomes included in-hospital death and all-cause mortality during follow up...

In this bicentric study, we report the outcomes of combined transcatheter aortic valve replacement combined with minimally invasive mitral valve surgery. We included a cohort of six patients (79.6 ± 3.2 years, 83% women) with high-risk profiles and deemed to be non-operable with combined mitral and aortic valvular disease. All patients had unsuitable anatomies for transcatheter mitral valve edge-to-edge repair (TEER). Moreover, most of the patients (5/6) suffered a combined aortic valve lesion, which complicates the efficiency of cardioplegia in the case of CBP through minimally invasive incisions...

BACKGROUND: The more severe the acute stroke is, the more serious myocardial damage is. This study aimed to determine the relationship between myocardial work and S100β, a quantitative biomarker of active cerebral lesions, in patients with acute ischemic stroke (AIS). METHODS: A total of 63 patients with AIS were examined by myocardial work echocardiography, 4D echocardiography with the measurement of left ventricular (LV) myocardial work, volume and function within 24-48 h of symptom onset, respectively...

OBJECTIVE: The aim of the study was to elucidate the long-term outcomes of atrial fibrillation (AF) surgery in AF patients with mitral valve (MV) disease and AF, by comparing the patients who underwent MV surgery with and without AF surgery. METHODS: Between 2005 and 2017, 2680 patients with AF who underwent MV surgery (MV surgery with AF surgery, n=1841; MV surgery without AF surgery, n=839) at 5 centers were included. After propensity score-matching, 1442 patients were extracted (AF surgery group, n=721; non-AF surgery group, n=721)...

Patients with atrial fibrillation (AF) should receive anticoagulation with warfarin or direct oral anticoagulants (DOACs) if the CHA2 DS2 -VASc (Congestive heart failure, Hypertension, Age 75 years or older [doubled], Diabetes, prior Stroke or transient ischemic attack or thromboembolism [doubled], Vascular disease, Age 65 to 74 years, Sex category) score is at least 2 in men or 3 in women. Antiplatelet therapy is not recommended. DOACs typically are the first-line therapy. Anticoagulation requires special consideration in some patient groups (eg, patients with bleeding problems should be considered for left atrial appendage occlusion devices, rather than anticoagulation)...

UNLABELLED: Cardioembolism associated with atrial fibrillation is a major cause of ischemic stroke. Left atrial appendage occlusion in atrial fibrillation patients undergoing cardiac surgery reduces the risk of postoperative stroke. A 78-year-old man with a history of atrial fibrillation and severe mitral regurgitation underwent thoracoscopic mitral valve repair with left atrial appendage clipping and the cryo-maze procedure 4 years previously. He was taking a direct oral anticoagulant for stroke prevention because his atrial fibrillation had recurred...

BACKGROUND: Cardioplegia solutions are used to protect the myocardium from ischemic injury caused by cardiopulmonary bypass and various types of cardioplegia solutions have been introduced for cardiac surgery. In this study, we aimed to compare the effects of del Nido cardioplegia and microplegia, which were mostly used in our clinic for intraoperative and postoperative processes among patients who underwent elective mitral valve replacement. As a result, the comparison could be performed in a specific patient group without additional valvular or coronary disease, and cardioplegia distribution could be achieved more efficiently...

BACKGROUND: Female sex is considered an independent predictor for mortality and morbidity following cardiac surgery. This study is to review the outcomes of adult cardiac surgery between males and females in a Saudi tertiary referral hospital. METHOD: This was a retrospective study for 925 adult patients operated on for ischemic coronary artery disease and acquired aortic and mitral valvular heart disease from 2015 to August 2023. We analyzed patient characteristics, intraoperative data, and postoperative results to compare outcomes between males and females...
