Catheter ablation of fascicular ventricular tachycardia.

Fascicular ventricular tachycardia (VT) is an idiopathic VT with right bundle branch block morphology and left-axis deviation occuring predominantly in young males. Fascicular tachycardia has been classified into three subtypes namely, left posterior fascicular VT, left anterior fascicular VT and upper septal fascicular VT. The mechanism of this tachycardia is believed to be localized reentry close to the fascicle of the left bundle branch. The reentrant circuit is composed of a verapamil sensitive zone, activated antegradely during tachycardia and the fast conduction Purkinje fibers activated retrogradely during tachycardia recorded as the pre Purkinje and the Purkinje potentials respectively. Catheter ablation is the preferred choice of therapy in patients with fascicular VT. Ablation is carried out during tachycardia, using conventional mapping techniques in majority of the patients, while three dimensional mapping and sinus rhythm ablation is reserved for patients with nonmappable tachycardia.

Angioplasty of membranous obstruction of inferior vena cava.

Membranous obstruction of vena cava (MOVC) is a common cause of hepatic venous outflow obstruction. Surgical procedures utilized to relieve symptoms carry a high morbidity and mortality. A patient who presented with gradual onset ascites and dilated, tortuous veins over the anterior abdominal wall and the back was found to have MOVC by inferior vena cavogram. Balloon dilatation of the obstruction was done successfully through a transvenous approach. Following this, the patient improved remarkably. The procedure is safe, effective and easy to perform. This balloon angioplasty provides alternative method for treatment of membranous obstruction of vena cava.

Streptococcus agalactiae endocarditis.

Streptococcus agalactiae (S. agalactiae) is a rare cause of infective endocarditis, which is associated with a high mortality rate. Endocarditis in adults is generally related to immunocompromised states. We hereby report the case of a 35 year old man who presented with fever and delirium in whom aortic valve endocarditis due to S. agalactiae was detected. Though most patients with S. agalactiae endocarditis need surgical intervention along with antibiotics, our patient improved with medical therapy alone.
