Rev-erb α, known as nuclear receptor 1D1 (NR1D1), regulates circadian rhythm, modulates glucose and lipid metabolism, and inflammatory response. However, little is known about the effect of Rev-erb agonist on the progression of myocardial infarction (MI) and heart failure. To investigate it, wild-type male mice underwent sham-operation or permanent ligation of the left anterior descending coronary artery to create MI model. Rev-erb agonist SR9009 (100 mg/kg/day) or vehicle was intraperitoneally administered...

Background: Bedside non-invasive techniques, such as radial artery tonometry, to estimate hemodynamic parameters have gained increased relevance as an attractive alternative and efficient method to measure hemodynamics in outpatient departments. For our pilot study, we sought to compare cardiac output (CO), and stroke volume (SV) estimated from a radial artery tonometry blood pressure pulse analyzer (BPPA) (DMP-Life, DAEYOMEDI Co., Gyeonggi-do, South Korea) to pulsed-wave Doppler (PWD) echocardiography derived parameters...

The development of fetal echocardiography and success in prenatal cardiac screening programs over the past 30 years has been driven by technical innovation and influenced by the different approaches of the various specialties practicing it. Screening for congenital heart defects no longer focuses on examining a limited number of pregnant women thought to be at increased risk, but instead forms an integrated part of a high-quality anatomical ultrasound performed in the second trimester using the 'five-transverse view' protocol...

Unintentional iatrogenic surgical complications can complicate the operative and postoperative courses of paediatric cardiac surgery patients. Unless recognized and treated early, it's possible, these complications may lead to a prolonged hospital stay, increased treatment cost, morbidity, and even death. Ventricular Septal Defect (VSD) is the most common congenital heart defect in children, occurring in 50% of all children with congenital heart disease and in 20% as an isolated lesion. Herein, we discuss the development of Superior Vena Cava (SVC) syndrome following surgical repair of VSD in a nine-month-old child...

AIMS: Ring annuloplasty is the gold standard of surgical repair in degenerative mitral valve disease. However, prosthetic annuloplasty has some drawbacks and potential hazards. Suture annuloplasty theoretically is able to preserve annular leaflet dynamics and left ventricular performance, but experience is limited. The aim of the study was to review the early and long-term outcome of the posterior double-suture annuloplasty (DSA) technique for degenerative mitral valve repair. METHODS: From January 2002 to December 2008, 400 patients underwent primary mitral valve repair for degenerative disease either with posterior DSA [n = 147 (37%)] or with flexible posterior annuloplasty band [n = 253 (63%)]...

We report on a morbidly obese 16-year-old boy (weight, 116 kg; height, 176 cm; body mass index, 35.5 kg/m2) with mitochondrial encephalomyopathy and a history of cerebral infarction, epilepsy, and severe mental retardation. The patient was scheduled for elective surgery under general anesthesia for multiple dental caries and entropion of the left eye. Preoperative examination results, including an electrocardiogram, were normal. No obvious cardiac function abnormalities were observed on echocardiography. Midazolam (10 mg) was administered orally as premedication 30 minutes before transfer to the operating room; however, the patient was uncooperative, and his body movements were difficult to control upon entering the operating room...

BACKGROUND: Recent data suggest that in cardiac surgical patients, the pulmonary artery acceleration time (PAT) is useful for estimating mean pulmonary artery pressure (MPAP) noninvasively with transoesophageal echocardiography (TOE). The pulmonary valve can be visualised from multiple echocardiographic windows, but it is unclear which, if any, view correlates best with MPAP. OBJECTIVE(S): To compare the PAT measured with TOE from oesophageal and transgastric views with MPAP obtained invasively with a pulmonary artery catheter...

BACKGROUND: Sepsis is a leading cause of mortality among patients in intensive care units across the USA. Thioredoxin-1 (Trx-1) is an essential 12 kDa cytosolic protein that, apart from maintaining the cellular redox state, possesses multifunctional properties. In this study, we explored the possibility of controlling adverse myocardial depression by overexpression of Trx-1 in a mouse model of severe sepsis. METHODS: Adult C57BL/6J and Trx-1Tg/+ mice were divided into wild-type sham (WTS), wild-type cecal ligation and puncture (WTCLP), Trx-1Tg/+sham (Trx-1Tg/+S), and Trx-1Tg/+CLP groups...

Advanced imaging techniques, including contrast echocardiography and CMR, provided valuable characterization and evaluation of a boy with an unusual cardiac mass. Imaging features assisted with differentiation of benign from malignant etiology and excluding thrombus. Accurate imaging techniques saved our patient risks associated with unnecessary surgery or anticoagulation. The ability to accurately define size serially assisted in guiding expectant management. He died from a noncardiac cause at age 28, and autopsy demonstrated a hamartoma of mature cardiac myocytes...

We studied a 50 years old male patient who underwent cardiac resynchronization therapy on and off (CRT-on and CRT-off) for assessment of left ventricular (LV) function and mechanical systole synchrony using gated myocardial perfusion imaging (gMPI) and real-time three-dimensional echocardiography (RT3DE). The patient was reexamined after seven months. The comparison of these two modalities showed consistent results on assessing both the CRT-on and CRT-off conditions. This result may indicate that an immediate synchronization parameter change during CRT-on may be valuable for predicting response to CRT surgery...

Varun Maheshwari, Brian Barr, Mukta Srivastava
Valvular heart disease (VHD) is a common clinical entity. Recognition of decompensated VHD is crucial to instituting appropriate workup and management. Initial evaluation focuses on hemodynamics, peripheral perfusion, volume overload, and active myocardial ischemia. Initial therapy is targeted at improving hemodynamics, fluid status, and decreasing myocardial ischemia before intervention. Echocardiography can rapidly identify VHD etiology and severity along with physical examination findings. Owing to improved survival with cardiac surgery over the past several decades, prosthetic valve dysfunction should be recognized and initial treatment understood...
