Percutaneous transseptal myocardial ablation with wire (PTSAW): a new technique.

Alcohol septal ablation has recently been described as a safe alternative to surgical myectomy for treatment of symptomatic patients with hypertrophic obstructive cardiomyopathy. We describe a case where percutaneous myectomy was performed by mechanically occluding the septal artery using thrombogenic floppy tips of used PTCA wires instead of alcohol, as the anatomy of the septal artery was not suitable for alcohol ablation.

Dandy-Walker cyst associated with occipital meningocoele.

One case of Dandy - Walker cyst associated with occipital meningocoele is presented. In this case magnetic resonance imaging demonstrated a Dandy - Walker cyst in direct communication with an occipital meningocoele. Occipital meningocoele might simply be an expression of increased intracystic pressure in Dandy-Walker cyst in embryonic life, or such association might suggest morphogenetic situation during embryogenesis.
