AV Malformations: Radiation Therapy

Surgical Management of Medium to Large Size Pulmonary AV Malformations- A Case Series

The communication between pulmonary artery and pulmonary vein or between a bronchial artery and the pulmonary vein is called as pulmonary arterio-venous malformation. Dyspnea on exertion, fatigue, nasal bleeding, bluish discoloration of lips and nail beds and hemoptysis are common presenting complaints. In childhood only 10% of cases are identified. Cerebral vascular accidents, brain abscess, h...

Rate-dependent AV delay optimization in cardiac resynchronization therapy.

BACKGROUND During cardiac resynchronization therapy (CRT), cardiac performance is dependent on an optimized atrioventricular delay (AVD). However, the optimal AVD at different heart rates has not been defined yet during CRT. METHOD The effects of an increase in heart rate by pacing or physical exercise on optimal AVD were studied in 36 patients with biventricular pacemakers/defibrillators. Th...

Embolisation therapy for pulmonary arteriovenous malformations.

BACKGROUND Pulmonary arteriovenous malformations are abnormal direct connections between the pulmonary artery and pulmonary vein which result in a right-to-left shunt. They are associated with substantial morbidity and mortality mainly from the effects of paradoxical emboli. Potential complications include stroke, cerebral abscess, pulmonary haemorrhage and hypoxaemia. Embolisation therapy is a...
