Panax ginseng is commonly used in Chinese medicine and Western herbal preparations. However, it has also been recently noted to be associated with some cardiac pathologies-including cardiogenic shock due to acute anterior myocardial infarction, trans-ischemic attack, and stent thrombosis. This study was aimed to elucidate acute and subacute effects of the low and high doses of standardized Panax ginseng extract (sPGe) on cardiac functions. Rats were randomly assigned to control group, acute low-dose group (ALD), subacute low-dose group (SALD), acute high-dose group (AHD), and subacute high-dose group (SAHD)...

BACKGROUND: Many candidates with ischaemic functional mitral regurgitation (FMR) have previously undergone coronary artery bypass grafting (CABG), in which transcatheter mitral valve repair can be reasonable for ameliorating the deteriorated hemodynamic and heart failure symptoms. We sought to elucidate the outcomes of MitraClip (MC) implantation in patients with symptomatic ischaemic FMR after CABG. METHODS: We investigated clinical characteristics, outcomes and predictive impact of previous CABG on mortality in ischaemic FMR patients who underwent MC implantation from two high-volume centres in Germany...

BACKGROUND: Patients with mitral stenosis and atrial fibrillation (AF) require anticoagulation for stroke prevention. Thus far, all studies on direct oral anticoagulants (DOACs) have excluded patients with moderate to severe mitral stenosis. OBJECTIVES: The aim of this study was to validate the efficacy of DOACs in patients with mitral stenosis. METHODS: The study population was enrolled from the Health Insurance Review and Assessment Service (HIRA) database in the Republic of Korea, and it included patients who were diagnosed with mitral stenosis and AF and either were prescribed DOACs for off-label use or received conventional treatment with warfarin...

OBJECTIVE: Between 2000 and 2008, the mitral valve (MV) repair rate in patients with severe mitral regurgitation (MR) at our low-volume Veterans Affairs hospital was 21%. After instituting a multidisciplinary valve team in 2009, we determined whether this rate increased and characterized the outcomes of patients with degenerative disease. METHODS: We retrospectively reviewed data from 103 MV operations performed at our hospital between 1/2009 and 8/2016. Mitral valve pathology was categorized as degenerative, rheumatic, endocarditis, ischemic, hypertrophic cardiomyopathy, or failed prior MV repair...

Mechanical complications of acute myocardial infarction include ventricular septal rupture (VSR), free wall rupture, and ischemic mitral regurgitation. Postinfarction VSR is a rare but serious complication of myocardial infarction. VSR has a lower incidence in the era of new reperfusion therapies. However, clinicians should be aware of this potentially fatal complication as the mortality remains extremely high. Early diagnosis and treatment are the cornerstones of achieving a better outcome.

Background: Valvular heart disease (VHD) is expected to become more prevail as the population ages and disproportionately affects older adults. However, direct comparison of clinical characteristics, sonographic diagnosis, and outcomes in VHD patients aged over 65 years is scarce. The objective of this study was to evaluate the differences in clinical characteristics and prognosis in two age-groups of geriatric patients with VHD. Methods: We retrospectively enrolled consecutive individuals aged ≥ 65 years from Guangdong Provincial People's Hospital and screened for VHD using transthoracic echocardiography (TTE) or transesophageal echocardiography (TEE)...

BACKGROUND: The CTSN (Cardiothoracic Surgical Trials Network) recently reported no difference in left ventricular end-systolic volume index or in survival at 2 years between patients with severe ischemic mitral regurgitation (MR) randomized to mitral valve repair or replacement. However, replacement provided more durable correction of MR and fewer cardiovascular readmissions. Yet, costeffectiveness outcomes have not been addressed. METHODS AND RESULTS: We conducted a cost-effectiveness analysis of the surgical treatment of ischemic MR based on the CTSN trial (n=126 for repair; n=125 for replacement)...

The left circumflex (LCX) artery is located close to the mitral valve (MV), making it susceptible to injury during MV surgery. We are reporting our experience in the diagnosis and management of this complication. We retrospectively reviewed our surgical and coronary angiography databases for patients with documented LCX artery injury during MV surgery between January 2000 and December 2016. The complication was associated with MV replacement (9/1313, 0.7%) but not MV repair (0/393, 0.0%). Eight patients (88...

Despite left ventricular (LV) dysfunction increases the risk of incidental acute ischemic stroke (AIS), the association between LV function and severity of neurological deficits after AIS remains unclear. Between November 2015 and October 1017, a total of 99 AIS patients were prospectively enrolled and categorized into two groups based on National Institute of Health Stroke Scale (NIHSS). The AIS patients with NIHSS <6 were allocated into Group 1 ( n = 50) and those with NIHSS ≥6 were into Group 2 ( n = 49)...

The presence of secondary mitral regurgitation is an unfavorable prognostic factor in patients with chronic ischemic heart disease. This type of regurgitation can be treated with medical therapy, cardiac resynchronization therapy, surgically or percutaneously but each strategy has controversial aspects. The purpose of this review is to discuss the most debated issues relative to the various modalities available to treat ischemic secondary mitral regurgitation, highlighting also future perspectives.

Ischemic mitral regurgitation (IMR) is a frequent complication after acute myocardial infarction (AMI) associated with a worse prognosis. The pathophysiological mechanisms of IMR are not fully understood, but it is known to be a complex process in which ventricular remodelling is the main causal factor. The various imaging techniques in cardiology and echocardiography fundamentally have contributed significantly to clarify the mechanisms that cause and progressively aggravate IMR. At present, different therapeutic options, the most important of which are cardio-surgical, address this problem...

BACKGROUND: The ideal surgical technique for ischemic mitral regurgitation (MR) is controversial. We introduced an extended posterior mitral leaflet (PML) augmentation technique for functional MR with severe tethering, which detached the PML from the annulus almost completely and augmented it with a large 3×6-cm oval pericardial patch. Methods and Results: A total of 17 mitral repairs using the new technique were performed for ischemic MR with no 30-day mortality and 2 hospital deaths...

ST-elevation myocardial infarction (STEMI) due to septic coronary embolism is a rare complication of infective endocarditis (IE) and is associated with high mortality rates. When common signs of IE are often overlooked on admission, the diagnosis may be established through complications, which may cause prominent symptoms. Here, we report a case of native mitral valve endocarditis with an unusual presentation with STEMI and concomitant ischemic stroke, which was due to multiple coronary and cerebral septic embolisms...

BACKGROUND: Mitral valve repair combined with papillary muscle approximation (MVr+PMA) may improve repair durability in severe ischemic mitral regurgitation (MR), when compared with MVr alone. We sought to identify preoperative transthoracic echocardiographic markers associated with MR recurrence after MVr+PMA. METHODS: A post-hoc analysis was performed on patients with severe ischemic MR who underwent coronary artery bypass grafting with MVr+PMA, in the Papillary Muscle Approximation Randomized Trial...
