BACKGROUND: Right ventricular (RV) function has prognostic value in terms of survival and symptoms in patients with mitral stenosis (MS). The aim of the study was to assess RV function by strain analysis in the patients of mitral stenosis and the effect of percutaneous transvenous mitral commisurotomy (PTMC) on it. METHODS: Eighty patients of severe mitral stenosis without overt right heart failure and normal sinus rhythm undergoing PTMC were included. Conventional echocardiography and RV function by TDI-derived longitudinal strain and strain rate were assessed prior and 24 hours post PTMC and compared with 40 healthy age-matched controls...

A patient's coronary artery calcium score (CACS) is a strong independent predictor of cardiovascular risk. Used in conjunction with traditional measures of risk, the CACS helps the clinician discuss cardiovascular (CV) risk and recommend therapies with the patient. We present several cases in which measurement of the CACS and traditional risk factors were used to help guide the clinician-patient conversation and guide therapies.

Early infectious endocarditis (IE) occurs in 3% of prosthesis in the first 12 months. Early IE is more aggressive than late prosthetic valve endocarditis. Mortality remains high, despite combined medical and surgical treatment. We present a case of early IE in aortic prosthetic valve complicated with paravalvular abscess, pseudoaneurysm and aorto- right atrial fistula.

This case series describes echocardiographic and computed tomography angiographic (CTA) characteristics, clinical features, diagnosis, and treatment in 15 patients of Pulmonary artery sling (PAS). Echocardiography is effective in diagnosing PAS, when the main pulmonary artery extends to the right pulmonary artery directly with the left pulmonary artery arising from the right pulmonary artery. CTA, clearly demonstrating the position and extent of trachea compression, the anatomy of PAS and the spatial relationships among the PAS, trachea and the esophagus, is necessary for the final diagnosis...

As coronary artery calcium (CAC) is atherosclerosis and not just a marker of cardiovascular (CV) disease, measurement of a patient's coronary artery calcium score (CACS) is a strong predictor of risk. Clinically performed in asymptomatic patients, the CACS, along with several CV risk factors, namely age, sex, ethnicity, diabetes, tobacco use, family history, cholesterol level, blood pressure, and use of cholesterol or hypertensive medications, provide a predictive model of 10 year risk for CV events. A smartphone "App" makes this quick to obtain and use...
