Nowadays, dental diseases are one of the most common illnesses in the world. Some of them can lead to translocation of oral bacteria to the bloodstream causing intermittent bacteraemia. Therefore, a potential association between oral infection and cardiovascular diseases has been discussed in recent years as a result of adhesion of oral microbes to the heart valves. The aim of this study was to detect oral bacteria on pathologically changed heart valves not caused by infective endocarditis. In the study, patients with pathologically changed heart valves were involved...

Lutembacher syndrome is characterized by a congenital ostium secundum atrial septal defect and an acquired mitral valve stenosis. We present a similar case in a 31-year old male who came in with orthopnoea, central cyanosis and pedal oedema. Examination revealed cardiac murmurs in tricuspid and apical regions. Chest x-ray showed signs of pulmonary congestion and ventricular enlargement. Electrocardiogaphy (ECG) revealed right axis deviation and right bundle branch block along with atrial fibrillation and Transthoracic Echocardiography (TTE) showed abnormal valves (mitral stenosis with calcification and tricuspid regurgitation) and dilated cardiac chambers...

BACKGROUND: Many patients with tetralogy of Fallot (TOF) who underwent surgical correction of their congenital cardiac malformation during infancy develop right ventricular dysfunction and exercise intolerance in the long term. The right ventricle (RV) dilates due to the development of severe pulmonary regurgitation (and secondary tricuspid insufficiency). To reduce RV dilation and improve exercise tolerance pulmonary valve replacement (PVR) is the common therapeutic strategy. Whether concomitant tricuspid valve repair (TVR) is beneficial in these pure volume-overload conditions is still unknown...

Background: MicroRNA-24 (miR-24) plays an important role in heart failure by reducing the efficiency of myocardial excitation-contraction coupling. Prolonged cardiac hypertrophy may lead to heart failure, but little is known about the role of miR-24 in cardiac hypertrophy. This study aimed to preliminarily investigate the function of miR-24 and its mechanisms in cardiac hypertrophy. Methods: Twelve Sprague-Dawley rats with a body weight of 50 ± 5 g were recruited and randomly divided into two groups: a transverse aortic constriction (TAC) group and a sham surgery group...

Anesthetic protocols may influence adrenal function. Effective methods for modulating stress are desirable to minimize secondary effects during the perioperative period. The aim of this study was to evaluate the effects of the administration of propofol with dexmedetomidine or ketamine on corticoadrenal function and heart and respiratory rates. A random treatment-order design was used: each rabbit received all treatments, with at least 14 d between experiments. Rabbits were assigned to 3 treatment groups (10 per group): group 1, 1 mL normal saline solution intravenously; group 2, propofol (3 mg/kg IV) and dexmedetomidine (0...

BACKGROUND: Aortic regurgitation (AR) is a valvular disease that can lead to systolic heart failure. Treatment options besides cardiac surgery are limited and consequently severe AR is associated with higher mortality and morbidity when not operated. In this investigation, we examined the effects of a novel cardiac myosin activator, Omecamtiv-mecarbil (OM), in rats with chronic severe AR. METHODS: AR was created by retrograde puncture of the aortic valve leaflets in 20 adults Wistar rats...

Patients with heart disease have a higher risk to develop cardiac arrhythmias, either spontaneously or drug-induced. In this study, we have used a rabbit model of myocardial infarction (MI) with severe left ventricular systolic dysfunction (LVSD) to study potential drug-induced cardiac risks with N-(piperidin-2-ylmethyl)-2,5-bis(2,2,2-trifluoroethoxy)benzamide (flecainide). Upon ligation of the left circumflex arteries, male New Zealand White rabbits developed a large MI and moderate or severe LVSD 7 weeks after surgery, in comparison to SHAM-operated animals...

BACKGROUND: Dexmedetomidine (DEX) is an α-2 adrenergic agonist with sedative and analgesic properties. Although not approved for pediatric use by the Food and Drug Administration, DEX is increasingly used in pediatric anesthesia and critical care. However, very limited information is available regarding the pharmacokinetics of DEX in children. The aim of this study was to investigate DEX pharmacokinetics and pharmacodynamics (PK-PD) in Mexican children 2-18 years of age who were undergoing outpatient surgical procedures...

Background: Patients with a diagnosis of coronary artery disease (CAD) may face important decisions regarding treatment options, with the "right choice" depending on the relative weights of risks and benefits. Studies performed as discrete choice experiments are used to estimate these weights, and attribute selection is an essential step in the design of these studies. Attributes not included in the design cannot be analyzed. In this study, we aimed to elicit, rank, and rate attributes that may be considered important to patients and physicians who must choose between angioplasty and surgery for coronary revascularization...

Percutaneous paravalvular leak (PVL) closure has emerged as a feasible alternative to redo valve surgery. However, comparative data on percutaneous and surgical treatment of PVL are scarce. We performed a systematic review and a meta-analysis of studies on percutaneous and surgical treatments of PVL. Of the 2,267 studies screened, 22 eligible studies were analyzed. Primary end points were technical success, 30-day mortality, stroke, and length of stay. Secondary end points were 1-year mortality, readmission for heart failure, reoperation, and symptomatic improvement at follow-up...

Chenni S Sriram, Mario D Gonzalez
We describe a neonate that developed alternating wide and narrow complex tachycardias following heart surgery for congenital heart defect. Although the etiology was sinus tachycardia, a premature atrial complex initiated aberrancy due to phase 3 block that was perpetuated due to 'linking' at similar or even slower heart rates. Similarly, there was abrupt transition from wide to narrow complex tachycardia following a premature ventricular complex without a change in subsequent heart rate. This was explained by interruption of linking phenomenon by premature ventricular activation...

BACKGROUND Routine hemodynamic monitoring parameters under general anesthesia, such as heart rate (HR), systolic blood pressure (SBP), and perfusion index (PI), do not solely reflect intraoperative nociceptive levels. We developed a hemodynamic model combining these 3 parameters for nociceptive responses during general anesthesia, and evaluated nociceptive responses to surgical skin incision. MATERIAL AND METHODS We first retrospectively performed discriminant analysis using 3 values - HR, SBP, and PI - to assess response to skin incision during tympanoplasty, laparoscopic cholecystectomy, and open gastrectomy to determine if combined use of these parameters differentiates nociceptive levels among these 3 surgeries...
