Strain echocardiography in predicting LV dysfunction in RV apical pacing.

Right ventricular (RV) pacing is associated with a reduction in left ventricular (LV) systolic function, thought to be mediated by pacing-induced ventricular dyssynchrony. The prevalence of heart failure after RV pacing is reported to range from 31±3%. We studied 60 subjects with high-grade atrioventricular block and Complete Heart Block (CHB) scheduled to undergo right ventricular apical pacing.

Pacemaker pocket infection rate and suture technique.

Objective: The incidence of cardiac implantable electronic device (CIED) infection is usually <2%. The interrupted suture technique is thought to be better than a continuous suture in order to prevent pacemaker pocket infection. The aim of this study was to determine if there was a correlation between the suture techniques and the pacemaker wound infection rate.

A Study on Cardiac Manifestations of Dengue Fever.

Aims: Incidence of cardiac involvement in dengue fever varies between 15 -50%. Cardiac manifestations of dengue fever include asymptomatic sinus bradycardia, transient AV blocks, transient ventricular arrhythmias, myocarditis and pericardial effusion. This study was done with the objective of finding actual incidence of different cardiac manifestations of dengue fever in our tertiary care hospital.

Broken guidewire - A tale of three cases.

Guidewire fracture is a rare complication of percutaneous coronary intervention. Retained guide wire fragments in the coronary tree can cause thrombosis, embolic phenomena, dissection, perforation, and vessel occlusion. The management of this complication is still debated and it involves conservative management of leaving wire alone, percutaneous retrieval of fractured fragment, use of second stent to crush the wire, or open heart surgery.

Abnormal origin of right coronary artery and use of Tiger catheter through femoral route.

Background: Abnormal origin of right coronary artery (RCA) is not uncommon. The incidence is .25-.

Syncope in a child.

Acute rheumatic fever (ARF) is a well-characterized illness. However, syncope in ARF due to advanced heart block is very rare. A 10-year-old boy was admitted with recurrent syncope for 12 h.

Our experience of coronary angiography with and without heparin.

Aim: Coronary angiography is usually done with heparin. Our aim is to see whether it can be done without heparin through femoral route and its effect on local complications.

Method: We have studied 3780 patients from 2006 to 2010 using standard dose Heparin (5000 units), low dose heparin (2000 units) and no heparin.

A case of primary ciliary dyskinesia with pulmonary arterial hypertension responding to oral sildenafil.

Primary ciliary dyskinesia (PCD) is an autosomal recessive heterogeneous group of conditions with variable clinical findings like recurrent respiratory tract infections, bronchiectasis, situs inversus, singly or in various combinations. Development of Pulmonary arterial hypertension can be a late complication of this disease. Here we present a case of PCD with recurrent respiratory tract infections, bronchiectasis and severe PAH, who responded to treatment with Oxygen, IV broad spectrum antibiotics and oral sildenafil.

Primary percutaneous coronary intervention in a case of idiopathic spontaneous coronary artery dissection.

Spontaneous coronary artery dissection (SCAD) is a rare but important cause of acute coronary syndrome. SCAD can cause unstable angina, acute myocardial infarction, and sudden death. The diagnosis of coronary dissection is usually made by coronary angiography.

An Uncommon Ventricular Tachycardia due to Inactive PPM Lead.

Our patient had recurrent syncope due to ventricular tachycardia (VT) after one year of VVI Pacemaker implantation. He had pacemaker pocket infection for which new pacemaker was implanted on opposite side but old lead was not explanted completely. Flouroscopy showed redundant loop of old lead in right ventricular inflow which was snared out subsequently.

Ventricular pseudo-aneurysm with coronary ectasias.

A 51 years male presented with acute left ventricular failure and was diagnosed to have pseudo-aneurysm of left ventricle, coronary artery disease with diffuse ectasia of coronary arteries.

A case of difficult temporary pacing.

A 55-year-old lady came with recurrent syncope due to complete heart block. A temporary pacing lead could not be advanced via the inferior vena cava (IVC) to the right atrium. A venogram demonstrated that the IVC had no connection to the right atrium.

Amelioration of immune cell number depletion and potentiation of depressed detoxification system of tumor-bearing mice by curcumin.

Background: The true therapeutic benefit of the use of natural products, especially acceptable dietary components such as curcumin, which can spare the normal cells and boost host immunity, has opened new horizons in cancer prevention and treatment.

Methods: In our model system we used Ehrlich's ascites carcinoma cells grown in peritoneal carity of Swiss albino mice and curcumin was fed every alternative day.

Results: Here, we report that curcumin administration to tumor-bearing mice decreased tumor cell number significantly in a dose-dependent manner.
