Ventricular Tachycardia in Repaired Double Chambered Right Ventricle - Identification of the Substrate and Successful Ablation

A 35 year old female presented with recurrent ventricular tachycardia 5 years after she had undergone surgical repair of double chambered right ventricle. Electroanatomical mapping showed a localised scar in the apex with double potentials and good pace map. Ablation here resulted in non-inducibility of ventricular tachycardia. We hypothesise that the scarring in the apex is the result of sustained pressure overload and becomes arrhythmogenic similar to the apical scar in patients with mid-ventricular hypertrophic cardiomyopathy

Dilemma of localization of culprit vessel by electrocardiography in acute myocardial infarction

Acute coronary syndrome (ACS) and electrocardiography showing ST elevation in Lead aVR > V1 are considered specific for left main coronary artery lesion and also suggest extensive anterior wall myocardial infarction. In this backdrop, we are presenting an incidental observation of an association of ST elevation in lead aVR > V1 in isolated proximal left circumflex lesion in the setting of ACS, who later underwent successful primary percutaneous coronary intervention

Anomalous left anterior descending artery from pulmonary artery: An extremely rare coronary anomaly

We report a rare coronary artery anomaly–anomalous origin of the left anterior descending artery from the pulmonary artery in a 40-year-old woman. The uniqueness of this case is the absence of any significant morbidity from this condition in adulthood which is in contrast to other reported cases where patients present with myocardial infarction, congestive heart failure, and sometimes death during the early infantile period.
