BACKGROUND: We aimed to investigate the characteristics and echocardiographic changes in patients with severe mitral stenosis (MS) who maintained sinus rhythm (SR) for at least 10 years after successful percutaneous mitral balloon valvuloplasty (PMV). METHODS: We retrospectively reviewed 107 patients who had successful PMV and follow-up echocardiography for at least 10 years without mitral valve surgery. Preprocedural, immediate postprocedural (PMV), and long-term follow-up echocardiography (at least 10 years after PMV) data were reviewed...

PURPOSE: To explore the relationship between central blood pressure (BP) parameters and cardiac structure and function parameters in healthy individuals. METHODS: Four hundred Chinese participants with no overt cardiovascular disease participated in this study. One hundred and seventy-one participants (42.8%) were male and the mean age was 60 years. Central BP was measured with the SphygmoCor system. Cardiac structure and function were assessed by echocardiography...

OBJECTIVES: Genetic variation is thought to contribute to considerable interindividual variability in platelet function, and there is a pressing need to identify genetic markers that can be used to predict the response to treatment. Our study investigated whether PEAR1, P2Y12, and UGT2A1 polymorphisms were associated with platelet reactivity in response to dual antiplatelet therapy in Chinese patients with acute coronary syndrome. METHODS: Patients with inhibition of platelet aggregation (IPA) < 30% after treatment were classified as the high platelet reactivity (HPR) group...

A variety of life-threating arrhythmias are caused by mutations in the cardiac voltage-gated sodium channel encoded by the SCN5A gene. In this study, we report a novel loss-of-function SCN5A variant, p.Ile1343Val (c.4027A>G), identified in a 42-year-old proband who presented with an unusual ECG with abnormal repolarization with biphasic T-waves in anteroseptal leads, persistent atrial fibrillation (AF), intermittent left bundle branch block (LBBB), and reversible cardiomyopathy. The patient did not meet the diagnostic criteria for Brugada syndrome, long QT syndrome, or any other known SCN5A-associated phenotype...

OBJECTIVES: To investigate the predictive value of four-dimensional (4D) strain echocardiography for major adverse cardiovascular events (MACE) in ST-elevation acute myocardial infarction (STEMI) patients. METHODS: Consecutive STEMI patients who underwent successful primary coronary interven tion (PCI) were enrolled and followed, with 2D and 4D strain echocardiography performed within 1 week after PCI. RESULTS: Twenty-six first MACE were recorded in 81 patients who finished a ∼3...

Septic shock with low cardiac output is very common in children. However, the mechanism underlying myocardial depression is unclear. The role of β3-AR in the development of myocardial depression in sepsis is unknown. In the present study, we generated an adolescent rat model of hypodynamic septic shock induced by lipopolysaccharide (LPS). Neonatal cardiomyocytes were also treated with LPS to mimic myocardial depression in sepsis, which was confirmed via an in vivo left ventricular hemodynamic study, and measurements of contractility and the Ca2+ transient in isolated adolescent and neonatal cardiomyocytes...

BACKGROUND: The effect of microRNA (miR)-495 on cardiomyocyte hypertrophy was explored by investigating the expression of proteins in the phosphatidylinositol 3-kinase (PI3K)/Akt signal pathway. METHODS: The study used a rat model of pulmonary arterial hypertension (PAH) induced by monocrotaline (MCT) administration (60 mg/kg) for 2 weeks. Arterial wall thickness and right ventricular hypertrophy were examined by hematoxylin and eosin (HE) staining in the lungs and hearts...

A giant right coronary artery aneurysm (60 × 70 mm in size) was incidentally found by chest X-ray as an abnormal right atrial enlargement, and it needed surgical resection. Although the majority of giant coronary artery aneurysms present with symptoms of coronary ischemia, this case presented without any specific symptom. This study indicates that when chest X-ray shows abnormal atrial enlargement, a differential diagnosis of giant coronary artery aneurysm may need to be considered.

OBJECTIVES: Recommendations regarding sports restriction are lacking for middle-aged athletes with anomalous coronary arteries originating from the opposite sinus of Valsalva (ACAOS). METHODS: Sixty-three patients with ACAOS were subdivided into ACAOS with (n = 38) or without (n = 25) an interarterial course (IAC). Sports behavior, either competitive (COMP) or recreational (REC), was evaluated at the time of diagnosis and after a median follow-up of 4.2 years. RESULTS: Mean age was 56 ± 11 years and 48 (76...

OBJECTIVES: To investigate whether serum fibroblast growth factor 21 (FGF21) levels can be used to predict the future development of major adverse cardiovascular events (MACEs). METHODS: This study included 253 patients who received subsequent follow-up, and complete data were collected for 234 patients. Independent predictors of MACEs were identified by using the Cox proportional-hazards regression analysis. The prognostic value of FGF21 levels for MACEs was evaluated by Kaplan-Meier survival analysis...

Systemic lupus erythematosus (SLE) is a major cause of nonbacterial thrombotic endocarditis (NBTE) associated with intracardiac sterile vegetations. It is rare for vegetations to present as an atrial tumor. This report describes a 48-year-old female with SLE and antiphospholipid syndrome complicated by recurrent thrombosis on anticoagulation. A large left atrial mass lesion was detected on echocardiography during a work-up for leg burning. Infective endocarditis could not be confirmed, and hence left atrial mass lesion was the most likely diagnosis...

OBJECTIVES: Atherosclerosis is almost absent in intramyocardial coronary arteries, while epicardial coronary arteries may show extensive occlusive disease. Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) expression has been implicated in atherogenesis. We aimed to investigate differences in arterial wall LOX-1 expression between human epicardial and intramyocardial coronary arteries. METHODS: Epicardial and intramyocardial total artery wall specimens were obtained from 13 male patients (aged 61...

Left ventricular (LV) twist serves as a compensatory mechanism in systolic dysfunction and its degree of reduction may reflect a more advanced stage of disease. AIM: The aim was to investigate twist alterations depending on the degree of functional mitral regurgitation (MR) by speckle-tracking echocardiography. METHODS: Sixty-three patients with symptomatic dilated cardiomyopathy (DCM) were included. Patients were divided according to MR vena contracta width (VCW): group 1 with VCW <7 mm (mild/moderate MR) and group 2 with VCW ≥7 mm (severe MR)...

Contrast-induced encephalopathy (CIE) following coronary angiography (CAG) is a very rare complication. Radiological signs such as cerebral oedema and cortical enhancement are of great importance in the diagnosis. We report a case of probable CIE in a 76-year-old gentleman following a normal diagnostic CAG that involved 120 mL of the iodinated contrast agent iohexol (Omnipaque 300). At 90 min postprocedure he became acutely confused with a normal non-contrast CT of the head. After 9 days of conservative treatment, the patient recovered spontaneously with no neurological deficits...

OBJECTIVES: Sacubitril/valsartan was approved recently for the treatment of patients with heart failure and reduced ejection fraction. We present 6 cases of ventricular arrhythmia, that occurred shortly after sacubitril/valsartan initiation, that required drug withdrawal. Other potential triggering factors of electrical storm were ruled out and, from the arrhythmic perspective, all of the patients were stable in the previous year. Our aim is to describe the possible association of sacubitril/valsartan with arrhythmic storm...
