BACKGROUND: Transcatheter aortic valve replacement (TAVR) is the method of choice for patients with severe aortic valve stenosis, who are ineligible or at high risk for surgery. Though TAVR leads to a significant reduction in mortality, a notable amount of patients are re-hospitalized early after TAVR. Parameters or biomarkers predicting outcome are therefore needed to identify patients who benefit most. Specific monocyte subsets have been associated with cardiovascular diseases and were shown to possess prognostic value...

Echocardiography is the cornerstone in the diagnosis of any valvular heart disease. The accurate diagnosis of aortic stenosis, the left ventricle function and the other heart valves evaluation are currently done by ultrasound alone. Prosthetic valve choice and dimensions prior to implantation can be done solely by proper use of echocardiography. The emergence of new methods to cure aortic stenosis such as trans-catheter aortic valve replacement (TAVR) emphasized the diagnostic value of cardiac ultrasound. The usefulness of echocardiography in TAVR can be divided in the baseline assessment (common to patients treated by conventional surgery), intra-procedural guidance of valve deployment and post-procedural follow-up...

This review summaries the utility, application and data supporting use of cardiac magnetic resonance imaging (CMR) to evaluate and quantitate aortic regurgitation. We systematically searched Medline and PubMed for original research articles published since 2000 that provided data on the quantitation of aortic regurgitation by CMR and identified 11 articles for review. Direct aortic measurements using phase contrast allow quantitation of volumetric flow across the aortic valve and are highly reproducible and accurate compared with echocardiography...

BACKGROUND CONTEXT: With more cement augmentation procedures done, the occurrence of serious complications is also expected to rise. Symptomatic central cement embolization is a rare but very serious complication. Moreover, the pathophysiology and treatment of intrathoracic cement embolism remain controversial. PURPOSE: In this case series, we are trying to identify various presentations and suggest our emergent management scheme for symptomatic central cement embolization...

The case is reported of a successful transcatheter implantation of an Edwards SAPIEN 3 valve (29 mm) into a failing tricuspid bioprosthesis (Sorin Pericarbon, 31 mm). The procedure was performed in a 69-year-old woman with post-rheumatic mitral and tricuspid valve disease. Multiple previous cardiac surgeries precluded the use of another surgical approach. A large, organized, two-piece thrombus in the enlarged right atrium was not considered an absolute contraindication to the procedure. The SAPIEN 3 valve was implanted under general anesthesia, via a femoral venous access, under three-dimensional transesophageal echocardiography guidance...

Type 2 diabetes is associated with higher rate of ventricular arrhythmias and this is hypothesised to be independent of coronary artery disease or hypertension. To investigate further we compared changes in left ventricular myocardial gene expression in Type 2 diabetes to patients in a control group with left ventricular hypertrophy. 9 control patients and 7 patients with type 2 diabetes with aortic stenosis undergoing aortic valve replacement had standard ECGs, signal averaged ECGs and echocardiograms prior to surgery...

BACKGROUND: The effects of left ventricular (LV) loading on myocardial deformation variables are not well-studied in the clinical setting. In the present study, we evaluated the effects of isolated changes in preload, afterload and heart rate on LV longitudinal strain, systolic (SR-S) and early diastolic strain rate (SR-E) in post-cardiac surgery patients. METHODS: Twenty-one patients were studied early after cardiac surgery. Longitudinal myocardial strain and SR were analysed off-line using 2-D speckle echocardiography...

BACKGROUND: Patent ductus arteriosus (PDA) ligation is usually performed by congenital cardiac surgeons. However, due to the uneven distribution of congenital cardiac surgeons in South Korea, many institutions depend solely on adult cardiac surgeons for congenital cardiac diseases. We report the outcomes of PDA ligations performed by adult cardiac surgeons at our institution. METHODS: The electronic medical records of 852 neonates at Chung-Ang University Hospital, Seoul, South Korea from November 2010 to May 2014 were reviewed to identify patients with PDA...

REVIEW
Chi Young Shim
Transthoracic echocardiography has become increasingly popular in clinical practice. It is used for the functional evaluation of patients with various cardiovascular diseases. Its use has been extended further in routine screening for cardiovascular health and in preoperative risk assessment before non-cardiac surgery because it is non-invasive, easy to perform, reproducible, and cost-effective. When the results of preoperative echocardiography contain abnormalities, the findings must be interpreted to determine clinical relevance...

Cor triatriatum sinistrum (CTS) is a congenital anomaly where the left atrium is divided into two compartments by a fibromuscular membrane. This report aims to add to the literature on a rare cardiac condition that can cause neurological morbidity. We report a case of a 19-year-old female with an infarct in the right middle cerebral artery (MCA) territory initially maintained on aspirin. Eighteen months later, she had recurrence of weakness, for which repeat transthoracic echocardiography (TTE) and re-evaluation of the first TTE demonstrated a hyperechoic membrane spanning the width of the left atrium, clinching the diagnosis of CTS...

OBJECTIVE: Speckle tracking, when combined with 3-dimensional (3D) left ventricular ejection fraction, might prove to be a more sensitive marker for postoperative ventricular dysfunction. This study investigated early outcomes in a cohort of patients with left ventricular dysfunction undergoing cardiac surgery. DESIGN: Prospective, blinded, observational study. SETTING: University hospital; single institution. PARTICIPANTS: The study comprised 73 adult patients with left ventricular ejection fraction <50% undergoing cardiac surgery using cardiopulmonary bypass...

OBJECTIVE: The objectives of this retrospective study were to characterize the clinical presentation, diagnostic findings, surgical approaches, intra-operative challenges and complications following the surgical treatment of cardiac myxoma in two of the largest referral hospitals in Jordan. METHODS: Medical records of all patients presented to the cardiology department during the period between 1984 and 2016 were reviewed. Criteria for inclusion in the study were: (1) patients who were presented for cardiac evaluation due to symptoms suggestive of a primary cardiac problem, (2) completed medical records, including results of echocardiography suggestive of intra-cardiac occupying mass, (3) the surgical operation was undertaken and intra-operative data was available, (4) a histological diagnosis of myxoma was available and (5) the discharge status and follow-up data were available for at least 2 years after initial surgery...

OBJECTIVE: A rat model of left atrial stenosis-associated pulmonary hypertension due to left heart diseases was prepared to elucidate its mechanism. METHODS: Five-week-old Sprague-Dawley rats were randomly divided into 2 groups: left atrial stenosis and sham-operated control. Echocardiography was performed 2, 4, 6, and 10 weeks after surgery, and cardiac catheterization and organ excision were subsequently performed at 10 weeks after surgery. RESULTS: Left ventricular inflow velocity, measured by echocardiography, significantly increased in the left atrial stenosis group compared with that in the sham-operated control group (2...

OBJECTIVE: Preliminary data suggest that nonalcoholic fatty liver disease is associated with early heart failure (HF). However, whether nonalcoholic steatohepatitis (NASH) is directly associated with echocardiographic changes in cardiac structure or function remains unknown.

The perioperative management of complex patients in a highly technical and subspecialized environment is the domain of the cardiac anesthesiologist. Evidence suggests that hemodynamic management using goal directed hemodynamic therapy (GDHT) improves patient outcome. Organ protection remains a main concern during cardiac surgery using extracorporeal circulation. Mortality can be decreased when remote ischemic preconditioning techniques (RIPC) are being used. Neurological outcomes can be improved with near-infrared-spectometry (NIRS), volatile anesthetics increase myocardial protection through preconditioning and perioperative echocardiography increases overall patient survival...
