Transcatheter closure of ruptured sinus of Valsalva type IV with misleading severe aortic regurgitation.

Unlabelled: We present an unusual case of ruptured sinus of Valsalva (RSOV) in the right atrium, progressive exertional dyspnea, occasional epigastric heaviness, and palpitations. The examination revealed high-pitch continuous murmur. On transthoracic echocardiography, there was a ~5-6 mm size RSOV of non-coronary sinus into right atrium, continuous turbulent flow, and unusual presentation of severe central aortic regurgitation jet with holodiastolic flow reversal seen in the descending aorta.

Effects of nickle, nickle-cobalt and nickle-cobalt-phosphorus nanocatalysts for enhancing biohydrogen production in microbial electrolysis cells using paper industry wastewater.

Paper industries are water-intensive industries that produce large amount of wastewater containing dyes, toxicity and high nutrient content. These industries require sustainable technology for their waste disposal and MEC could be one of them. However, effective MEC operation at neutral pH and ambient temperature requires economical and efficient cathodes that are capable to treat indusial wastewater along with recovery of energy/biohydrogen.

Enhancing biohydrogen production from sugar industry wastewater using Ni, Ni-Co and Ni-Co-P electrodeposits as cathodes in microbial electrolysis cells.

Microbial electrolysis cell (MEC) can be utilized for the simultaneous treatment of actual industry wastewater and biohydrogen production. However, efficient and cost-effective cathode, working at ambient conditions and neutral pH, are required to make the MEC as a sustainable technology. In this study, MEC with electrodeposited cathodes (co-deposits of Ni, Ni-Co and Ni-Co-P) were utilized to evaluate the treatment efficiency and hydrogen recovery of sugar industry wastewater.

Nonselective Beta-Blockers Do Not Affect Survival in Cirrhotic Patients with Ascites.

Background: The role of nonselective beta-blockers in cirrhotic patients with ascites has been recently questioned; however, definitive evidence in this regard is still lacking.

Aims: To analyze published data on the influence of nonselective beta-blockers as compared to control group on survival of cirrhotic patients with ascites.

Methods: Computerized bibliographic search on the main databases was performed.

[The first 200 transcatheter aortic valve implantations in the Gottsegen Gyorgy Institute of Cardiology, Hungary].

Introduction: Transcatheter aortic valve implantation is a therapeutic alternative for contraindicated and high surgical risk patients with severe symptomatic aortic stenosis. This intervention is part of daily routine in the Institute of the authors.

Aim: In the present work the results of the first 200 patients are discussed.

Radial left ventricular dyssynchrony by speckle tracking in apical versus non apical right ventricular pacing- evidence of dyssynchrony on medium term follow up.

Introduction: To study effects of various sites of right ventricular pacing lead implantation on left ventricular function by 2-dimensional (2D) speckle tracking for radial strain and LV dyssynchrony.

Methods: This was retrospective prospective study. Fifteen patients each with right ventricular (RV) apical (RV apex and apical septum) and non-apical (mid septal and low right ventricular outflow tract [RVOT]) were programmed to obtain 100% ventricular pacing for evaluation by echo.

Mitral Stenosis, LV Aneurysm, Myocardial Bridge, and Myocardial Infarction: The Mystery Demystified.

Coronary embolisation, spontaneous coronary artery dissection, and myocardial bridges are rare causes of Myocardial Infarction (MI) in the youth. Here, we report a young male who developed myocardial infarction at the age of 19. Investigations revealed that he had mitral stenosis, myocardial bridge, and angiographic features of healed coronary dissection.

Cardiac rhabdomyoma in familial tuberous sclerosis.

Cardiac rhabdomyomas are often associated with tuberous sclerosis in infants. We report a 5 month old child presented with a tumor in the right ventricle and echocardiography features of rhabdomyoma. Both the child and her father had cutaneous features of tuberous sclerosis.

Neovascularization in left atrial myxoma.

We report a case with a left atrial mass who underwent coronary angiography to rule out coronary artery disease. Coronary angiography revealed an anomalous tortuous vascular structure originating from the left circumflex coronary artery to the left atrial tumor suggestive of neovascularization. Preoperative coronary angiography is useful for coronary artery evaluation and also provides additional information regarding the feeding vessel supplying the mass.

Clinical profile of patients hospitalized with heart failure in Bharatpur, Nepal.

Introduction: Heart failure (HF) is a common cardiovascular condition whose incidence and prevalence are increasing. Being a common reason for urgent hospital admission, it is a major cause of morbidity and mortality for the patients. In the developed countries coronary artery disease remains the leading cause of HF, whereas, in the underdeveloped countries, rheumatic heart disease leading to valvular lesion still remains the commonest causes of HF admission.

Usefulness of Doppler derived end diastolic flow gradient across the patent ductus arteriosus in selecting coils for ductal occlusion.

Transcatheter closure of patent ductus arteriosus (PDA) with coils is accepted as an alternative to surgical ligation. We evaluated whether flow gradient across PDA, obtained by Doppler echocardiography, can aid in selecting coils for percutaneous ductal occlusion. 79 consecutive patients with PDA, who underwent successful percutaneous coil occlusion were retrospectively reviewed.
