Severe Tricuspid Regurgitation Leads to Underestimation of the Severity of Mitral Stenosis by Doppler.

• RV volume overload causes septal flattening which leads to reduced transmitral flow. • In severe TR, MVA calculated by Doppler techniques is unreliable. • In MS with concomitant TR, 3D MPR planimetry is reliable for MVA calculation.

What to do with a protruding coronary stent in the aorta?

Coronary artery stents protruding into the aorta is a rarely reported problem. Issues with the protruding stent include embolization and interference with aortic valve function. Management of this rare situation should be on an individualized basis.

Outcomes after surgery for infective endocarditis.

Unlabelled: The role of surgery in infective endocarditis is becoming established the world over. In spite of all recent advances, endocarditis remains a lethal disease following surgery. With the emergence of more difficult-to-treat microorganisms, sicker and older patients with multiple co-morbidities, and an increase in healthcare-associated infections, the need for surgery in the management of infective endocarditis is only bound to increase.

Selecting the appropriate patients for coronary artery bypass grafting in ischemic cardiomyopathy-importance of myocardial viability.

Patients who undergo coronary artery bypass graft (CABG) surgery in ischemic cardiomyopathy have a survival advantage over medical therapy at 10 years. The survival advantage of CABG over medical therapy is due to its ability to reduce future myocardial infarction, and by conferring electrical stability. The presence of myocardial viability does not provide a differential survival advantage for CABG over medical therapy.

Changes in Soft Tissue Variable of Lips Following Retraction of Anterioir Teeth- A Cephalometric Study.

Aim: The purpose of this study was to assess the short-term perioral soft tissue variations of the lips before and after treatment cases in 15 patients with bi-maxillary protrusion using treated lateral cephalograms who had already achieved active growth.

Methodology: Fifteen pre-treatment and post-treatment lateral cephalometric radiographs of 18-25-year-old individuals with bimaxillary protrusion treated with all four 1 premolar extractions were accessed from the records. From the reference planes and landmarks, 13 horizontal, 10 vertical, and 2 angular measurements were noted.

Comparison of the Bleached and Non-Bleached Teeth for the Adhesive Boosters for the Orthodontic Bonding: An Original Research.

Introduction: The bleaching of the teeth is known to reduce the bonding of the orthodontic brackets. Hence, this study was piloted to analyze if there was any variance between the teeth that were and were not bleached when the adhesive boosters were used and for its effect on the shear bond strength.

Materials And Procedures: Hundred premolars (maxillary) that had been excised were randomly split into two groups: bleached teeth and unbleached teeth.

Evaluation of the Remineralisation of the Demineralized Enamel Surrounding Orthodontic Brackets using the Nano Hydroxyapatite: An Original Study.

Introduction: The orthodontic appliances have been known to accelerate enamel loss due to various reasons. Since there are few studies supporting the role of the nano-HAP in the mineralization of the demineralized tooth surfaces, the current study compared nano-HAP's capacity to remineralize the demineralized enamel layer surrounding braces at various concentration levels.

Materials And Procedures: This investigation involved 60 healthy permanent premolars that had just been excised.

Evaluation of Cervical Vertebral Maturation Angular Measurements as a Tool to Assess Skeletal Maturity: A Radiological Study.

Aim: The purpose of the present research was to evaluate the comparison between the Skeletal Maturation phases of Fishman's hand-wrist skeletal maturation index (SMI) and cervical vertebral maturation angle (CVMA).

Methodology: Assessment and comparison of Skeletal Maturation utilizing the hand-wrist bone radiograph by Fishman's system of skeletal maturation indicator (SMI), cervical vertebra maturation stages (CVMS), and lateral cephalogram by cervical vertebral maturation angle (CVMA) conducted on 150 subjects (75 male and 75 female). Chi-square was used to reveal the significance of study parameters on a categorical scale between SMI, CVMS, CVMA, and multiple regression analysis conducted to envisage the connotation of the dependent variable.

Assessment of Changes in the Upper Airway in Children with Finger Sucking Habit Using Cephalometric Radiographs.

Introduction: The persistence of the sucking beyond a certain age has been attributed to many deleterious effects on the orofacial structures. Hence, the present study evaluates the alterations in the upper airway among the children with and without the finger-sucking habits.

Material And Methods: We piloted an observational study among 58 children with malocclusion who required orthodontic treatment, in which between 7 and 12 years were selected.
