Surgical treatment of intracardiac leiomyomatosis can result in satisfactory midterm to long-term survival and satisfactory heart function. Multiple surgical strategies should be tailored to the anatomic characteristics of the intracardiac leiomyoma. Recurrence of intracardiac leiomyomatosis after the resection procedure may result in unfavorable late result.

With the use of ammonia borane as a hydrogen source, a borane catalyzed metal-free transfer hydrogenation of pyridines was successfully realized for the first time to furnish a variety of piperidines in 44-88% yields with moderate to excellent cis-selectivities. The ease in handling without requiring high pressure H makes this transfer hydrogenation practical and useful.
