Optimal mitral valve operation requires adequate exposure without impairment of atrial physiology, namely sinus node and atrioventricular node function. We used an extended vertical transseptal atrial approach in 34 consecutive patients. The extended vertical transseptal approach combines two semicircular atrial incisions circumscribing the tricuspid and(More)
During a 9-year period 80 patients with drug-resistant sustained ventricular tachycardia underwent direct surgical ablation of arrhythmogenic myocardium. Sixty-nine were male (86%) and 11 female (14%), with 1.9 +/- 1.1 (standard deviation) ventricular tachycardia morphologies per patient. The mean number of drugs failed was 3.7 +/- 1.6 per patient. The(More)
Using cationic liposomes to deliver cytotoxic molecules to the tumor microvasculature is currently being developed for the treatment of cancer and other angiogenesis-related diseases. To improve on their beneficial properties, the authors have examined whether the particular cationic lipid type and lipid content employed are important factors influencing(More)
We describe our experience with operative therapy for atrioventricular (AV) node tachycardia using an anatomically guided procedure. The operative rationale was to dissect the AV node from most of its atrial inputs (AV node "skeletonization") with the intent of altering the perinodal substrate and preventing reentry. The anteroseptal and posteroseptal(More)
Atrial flutter is associated with a macro-reentrant loop including an area of slow conduction cryoablation of which prevents atrial flutter to occur. Three patients underwent such intervention. Atrial fibrillation is associated with multiple reentrant circuits (leading circle of Allessie) that requires a critical surface area to perpetuate. We have designed(More)
Malaria still remains uncontrolled affecting millions and killing many. We have found the high chloroquine-resistance in Rajasthan epidemic which contains multipleP.falciparum strains. Large number of variantP.falciparum strains exist in India which should be taken into account for future malaria control strategies. We have characterised several parasite(More)
We report our experience with 43 consecutive patients with left free wall pathways operated on since December 1988 using a modified direct epicardial approach through a medial sternotomy, without the adjunct of normothermic cardiopulmonary bypass. The left atrioventricular sulcus is exposed by dislocating the heart cephalad and to the right using a sling(More)
A left subcostal surgical approach was used to implant an automatic implantable cardioverter defibrillator (AICD) in 48 patients with a history of nonfatal cardiac arrest or documented ventricular tachycardia/fibrillation. Electrophysiologic studies before surgery yielded induction of monomorphic or polymorphic ventricular tachycardia in 40 patients,(More)
Surgical treatment of sustained ventricular tachycardia due to nonischemic causes is uncommon. Nonischemic ventricular tachycardia was treated in 14 patients by map-directed surgical ablation of an arrhythmogenic site. There were 9 male and 5 female patients. The mean age was 33 +/- 13.4 years (range, 15 to 57 years). The etiology was idiopathic in 4(More)
