DESCRIPTION: A 40-year-old lady was admitted with a week’s history of fever and dyspnoea. Transthoracic echocardiography revealed 0.5 × 0.5 cm vegetation on the posterior mitral leaflet with a severe eccentric mitral regurgitation (MR) hugging the left atrial aspect of anterior mitral leaflet and the interatrial septum (IAS) which was confirmed by a transoesophageal echocardiogram BMJ Case Reports 2011;10.1136/bcr.03.2011.3993

DESCRIPTION: Pericardial cysts are rare benign mediastinal masses usually detected in asymptomatic individuals. Rare complications include compression of the bronchi, ventricular outflow tract, rupture with tamponade and sudden death. Treatment in symptomatic individuals includes surgical resection or percutaneous aspiration. BMJ Case Reports 2012;10.1136/bcr-03-2012-5984,

Description: Ebstein’s anomaly, a rare congenital cardiac malformation, is associated with a worse prognosis when it presents early as heart failure in the fetus and neonate. ▸ Targeted fetal echocardiography helps in risk stratification of such high-risk pregnancies towards more aggressive management.

Abstract: Techniques of implanting pacing leads in the right ventricle (RV) have evolved over time and involve the use of preshaped stylets. However, in the presence of venous abnormalities, it could be very challenging to do the same. We describe two cases with complex superior vena caval (SVC) anatomy which could be negotiated only with the use of a slittable coronary sinus guiding sheath and successful placement of pacing lead in the right ventricle.

Abstract: Carotid artery stenosis is a disabling disease in all age groups. Elderly people are more prone to recurrent strokes due to advancing age and multiple co-morbidities. Treatment options for symptomatic carotid stenosis in the very elderly are the same as in younger patients although with a higher operative risk. We describe a successful case of carotid artery stenting in a nonagenarian with symptomatic carotid artery stenosis, a subgroup for whom treatment options are rarely discussed in guidelines Australas Med J. 2012; 5(10): 528–530. doi: 10.4066/AMJ.2012.1278

Abstract OBJECTIVE:The purpose of this study was to examine the safety and efficacy of the Frontrunner XP CTO (chronic total occlusion) catheter (Cordis Corporation) for recanalization of CTO of femoropopliteal arteries. METHODS:A retrospective analysis of consecutive patients with critical limb ischemia (CLI) who underwent femoropopliteal angioplasty for TransAtlantic Inter-Society Consensus (TASC) class D lesions between 2009 and 2011 was performed. Twenty-two patients were enrolled with a mean age of 58.9 ± 11.5 years. Patients were enrolled with totally occluded arteries (mean occlusion length, 18.0 ± 10.1 cm) that were treated with the Frontrunner XP CTO catheter. All lesions were complex (TASC D) and 86.4% of the lesions were mildly calcified. A Frontrunner catheter was used to treat 22 CTOs after guidewire failure. RESULTS:Twenty-two of the 33 cases (66.7%) had failed previous attempts of percutaneous intervention with conventional guidewire. The Frontrunner catheter was used to treat 22 CTOs after guidewire failure. The Frontrunner catheter successfully facilitated the placement of a guidewire into the distal true lumen in 21 cases (95.5%). Thrombolysis in Myocardial Infarction 3 flow was achieved in all target vessels after further balloon angioplasty or stenting. CONCLUSIONS:The Frontrunner XP CTO catheter is safe and effective for successful recanalization of CTO of femoropopliteal arteries and it should be an alternative method after guidewire failure.

Abstract: Coronary Artery Disease (CAD), caused by the buildup of plaque on the inside of the coronary arteries, has a high mortality rate. To efficiently detect this condition from echocardiography images, with lesser inter-observer variability and visual interpretation errors, computer based data mining techniques may be exploited. We have developed and presented one such technique in this paper for the classification of normal and CAD affected cases. A multitude of grayscale features (fractal dimension, entropies based on the higher order spectra, features based on image texture and local binary patterns, and wavelet based features) were extracted from echocardiography images belonging to a huge database of 400 normal cases and 400 CAD patients. Only the features that had good discriminating capability were selected using t-test. Several combinations of the resultant significant features were used to evaluate many supervised classifiers to find the combination that presents a good accuracy. We observed that the Gaussian Mixture Model (GMM) classifier trained with a feature subset made up of nine significant features presented the highest accuracy, sensitivity, specificity, and positive predictive value of 100%. We have also developed a novel, highly discriminative HeartIndex, which is a single number that is calculated from the combination of the features, in order to objectively classify the images from either of the two classes. Such an index allows for an easier implementation of the technique for automated CAD detection in the computers in hospitals and clinics.

Abstract: Aims: Patients with severe sepsis and septic shock often exhibit significant cardiovascular dysfunction. We designed the study with an aim to determine the severity of cardiac dysfunction in the different group of sepsis patients. Study Design: Single-center, cross-sectional study Place and Duration of Study: The study was carried out at Department of Cardiology, Kasturba Medical College and Hospital, Manipal from June 2011 to December 2012. Methodology: A total of 74 patients who were diagnosed with sepsis were enrolled in the study. All patients were subjected to routine analysis, laboratory test and echocardiogrphic assessment. Results: The patients were divided into 3 groups: sepsis group (n = 11), severe sepsis group (n = 37) and septic shock group (n = 26). The mitral E/A value is significantly higher in patients with septic shock than that of the patients with sepsis (P = 0.04). The indices of right ventricular dysfunction did not show any significant difference in the patients with septic shock and that of sepsis. Conclusion: Left ventricular dysfunction may be considered prevalent in sepsis as per the significant E/A values. However, the other echocardiographic parameter should also be considered. This may even infer that cardiac dysfunction may not correlate with the severity of sepsis. British Journal of Medicine and Medical Research, ISSN: 2231-0614,Vol.: 5, Issue

Description: In normal participants, the left anterior descending (LAD) artery arises from the left coronary artery (LCA) and courses along the anterior interventricular sulcus (AIVS) until it reaches the apex. Dual LAD circulation is an uncommon coronary anomaly in which there are two LAD arteries. A type 4 dual LAD circulation is an extremely rare variant of a dual LAD in which one of the LAD arteries arises from the right coronary artery (RCA).

Aims: Durable polymers used for first-generation drug-eluting stents (DES) potentially contribute to persistent inflammation and late stent thrombosis. The Supraflex (Sahajanand Medical Technologies Pvt. Ltd., India) is a cobalt-chromium, balloon-expandable DES system that incorporates an ultra-thin strut thickness (60µm), a biabsorbable polymer and sirolimus. The aim of the MANIPAL-FLEX first-in-man (FIM) study was to assess the safety and efficacy of the Supraflex sirolimus-eluting stent (SES) implantation, in de novo coronary artery disease (CAD), using clinical and quantitative coronary angiography (QCA) follow-ups
