Dual atrio ventricular node in heterotaxy syndrome.

Our interesting electrocardiogram has two qRS morphology without features of preexcitation suggesting two atrio ventricular node conduction system. All cardiologists should be aware of this feature in heterotaxy syndrome as reentrant supraventricular tachycardia may develop in these patients.

Takayasu's Arteritis in Pregnancy: Challenges During the Ongoing Coronavirus Disease 2019 Pandemic for Optimal Maternal and Neonatal Outcomes.

Takayasu's arteritis is a rare systemic vasculitis affecting the aorta and its primary branches. In developing countries, it is often associated with late diagnosis and high morbidity and mortality. We report a case of Takayasu's arteritis diagnosed in the postpartum period and discuss the challenges faced for optimal outcomes during the ongoing coronavirus disease 2019 pandemic.

Prognostic value of late gadolinium enhancement in cardiac MRI of non-ischemic dilated cardiomyopathy patients.

Background: The role of late gadolinium enhancement (LGE) in cardiac MRI (CMR) as prognostic marker in non-ischemic dilated cardiomyopathy (NIDCM) is evolving.

Objective: To study the effect of LGE in the prognosis of NIDCM patients.

Methods: 112 consecutive NIDCM patients, who underwent CMR, were prospectively followed up for 745 ± 320 days.

Ductal aneurysm with postsubclavian coarctation of aorta in an adult.

We describe a case of ductal aneurysm in an adult patient with post subclavian coarctation of aorta, which is a very rare association.

Takotsubo syndrome presenting as syncope in a patient with permanent pacemaker.

Takotsubo syndrome is an acute reversible heart failure syndrome triggered by physical or emotional stress, especially in postmenopausal women. Herein, we describe a case of a 31-year-old pacemaker dependent lady who presented with syncope after she was bereaved of her father. Electrocardiogram at admission revealed ventricular paced rhythm at 60/min, prolonged QT interval and frequent runs of torsades de pointes.

HLA-DR typing in polyarticular juvenile idiopathic arthritis: a study from a tertiary care hospital in northern India.

Introduction: Many studies of human leukocyte antigen (HLA) association with juvenile idiopathic arthritis (JIA) have reported conflicting results, which were probably related to ethnic differences. Moreover, in India, studies on HLA-DR typing on JIA, particularly polyarticular JIA, is lacking.

Objective: The aim of our study was to reveal the frequency of HLA DR types in a cohort of polyarticular JIA in northern India.
