Informal training in preclinical research may be a contributor to the poor reproducibility of preclinical cardiology research and low rates of translation into clinical research and practice. Mouse echocardiography is a widely used technique to assess cardiac structure and function in drug intervention studies using disease models. The inter-observer variability (IOV) of clinical echocardiographic measurements has been shown to improve with formalized training, but preclinical echocardiography lacks similarly critical standardization of training...

BACKGROUND/AIMS: Many clinical and experimental studies have shown that treatment with statins could prevent myocardial hypertrophy and remodeling induced by hypertension and myocardial infarction. But the molecular mechanism was not clear. We aimed to investigate the beneficial effects of atorvastatin on hypertension-induced myocardial hypertrophy and remodeling in spontaneously hypertensive rats (SHR) with the hope of revealing other potential mechanisms or target pathways to interpret the pleiotropic effects of atorvastatin on myocardial hypertrophy...

AIMS: Success of opening single (SOS)-comedy is a prospective multicenter study to compare the improvement in the decrease of myocardial viability by percutaneous coronary intervention (PCI) with that by optimal medical therapy (OMT) alone in patients with chronic total occlusion (CTO) of a single coronary artery. METHODS AND RESULTS: The risks and the benefits of both options (PCI and OMT) were listed in a CTO decision aid (DA). Eligible participants detected by invasive coronary angiography (ICA) or coronary computed tomography angiography (CCTA) were divided into PCI or OMT groups according to patients' choice after shared-decision making process with DA...

Cardiac metastases from oral squamous cell carcinoma (SCC) are rare, especially in the absence of systemic metastasis. We describe a case of a patient presenting with chest pain and ECG abnormalities concerning for ST-elevation myocardial infarction that eventually was found to have an incidental right ventricular mass on chest CT angiogram. Ultimately, she had an intracardiac echocardiography-assisted biopsy diagnosis of isolated cardiac metastasis from primary oral SCC. The extent of the disease precluded any surgical intervention, and the patient subsequently transitioned to hospice care...

Introduction: Firearm-related injuries account for 20% of all injury-related deaths and are responsible for 105,000 injuries annually. The occurrence of bullet emboli to the heart is exceedingly rare. Given the rarity of emboli, controversy exists over management. The primary endpoint of this study is to establish a management algorithm for venous bullet emboli to the heart. Materials and methods: A literature search was performed using PubMed and Google Scholar with the following search terms: cardiac bullet embolus, cardiac missile embolus, and bullet embolus...

Interrupted aortic arch (IAA) is a rare form of critical neonatal heart disease in which there is lack of continuity between the ascending aorta and the descending thoracic aorta. In the absence of prenatal diagnosis, patients with IAA present in shock when the patent ductus arteriosus closes. Diagnosis can generally be made by echocardiography, and initiation of prostaglandin E1 infusion allows for adequate lower body perfusion prior to surgical repair. Full neonatal repair can be achieved with good outcomes in most cases...

The right ventricle and tricuspid valve (TV) have long been neglected by cardiologists. Functional tricuspid regurgitation (TR) is nowadays the most common cause of severe TR and is emerging as a prognostic factor in many heart diseases. A multimodality imaging approach is fundamental for defining the pathophysiology of TR, using both 2-dimensional and 3-dimensional (3D) echocardiography, as well as CT scan. In particular, 3D echocardiography can characterize TV apparatus and tricuspid annulus; CT offers complementary information about annular structure, and its relationship with the right coronary artery...

Atrial masses are rare and more often localized in the right atrium. They are usually detected incidentally, and the leading causes are tumors, thrombi, or infective vegetations. However, normal structures and artifacts ("pseudomasses") should also be considered in differential diagnosis, especially after cardiac and/or aortic surgery. We present a case of an unusual left atrial image observed on transthoracic echocardiography in an 83-year-old woman after an intervention of open-chest ascending aorta replacement and myocardial revascularization...

Background: Left ventricular remodeling (LVR) after ST-elevation myocardial infarction (STEMI) harbingers poor prognosis. Three-dimensional echocardiography (3DE) is more accurate than 2 D echo for the assessment of left ventricle (LV) shape. We assessed LV geometry with 3D ECHO 6 months after STEMI in patients who had primary angioplasty. Materials and Methods: In this prospective study, morphological and functional analysis of LV with 3D ECHO (volumes, LVEF, 3D sphericity index [SI]) was assessed up to 7 days and 6 months in 42 STEMI patients...

BACKGROUND: Treatment of nonculprit coronary stenosis during primary percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction may be beneficial, but the mode and timing of the intervention are still controversial. The aim of this study was to examine the significance and prognostic value of preserved coronary flow velocity reserve (CFVR) in patients with nonculprit intermediate stenosis early after primary percutaneous coronary intervention. METHODS: Two hundred thirty patients with remaining intermediate (50%-70%) stenosis of non-infarct-related arteries, in whom CFVR was performed within 7 days after primary percutaneous coronary intervention, were prospectively enrolled...

Adaptation and evolution of transcatheter aortic valve replacement (TAVR) technologies has led to approval of TAVR for consideration in patients at intermediate risk for surgical aortic valve intervention. As TAVR becomes more mainstream, attention is shifting toward percutaneous mitral valve (MV) repair and transcatheter MV replacement (TMVR) techniques. Transcatheter heart valves (both purpose-built and off-label-use TAVR valves) are being implanted during TMVR procedures to treat clinically significant MV disease (native disease, degenerated bioprosthetic valves, and dysfunctional surgical MV annuloplasty repairs) when the risk of open heart MV surgery is prohibitive...

A 50-year-old man presented with acute onset dyspnea following cocaine use. He had severe aortic stenosis (AS), mild mitral regurgitation (MR) due to mitral valve prolapse, and no coronary artery disease on recent coronary angiography. He was in acute heart failure with signs of impending cardiogenic shock. Urgent bedside echocardiography revealed hyperdynamic left ventricular systolic function with acute severe MR from a ruptured chordae tendineae. The acute cocaine-induced spike of his already elevated left ventricular systolic pressure from severe AS likely precipitated chordal rupture of his vulnerable mitral valve...
