HEADLINE: HYPERTROPHIC CARDIOMYOPATHY: Researchers discuss treatments for obstructive hypertrophic cardiomyopathy
BODY:
Researchers discuss treatments for obstructive hypertrophic cardiomyopathy.
According to recent research from the United States, "Our understanding of
the pathophysiology of obstruction in hypertrophic cardiomyopathy has evolved
since initial descriptions in the late 1950s.
"This review addresses the cause of obstruction, from early ideas that a
muscular outflow tract sphincter was the cause, through the discovery of
systolic anterior motion (SAM) of the mitral valve, to current understanding
that flow drag, the pushing force of flow, is the dominant hydrodynamic
mechanism for SAM," wrote M.V. Sherrid and colleagues, Columbia University, St.
Luke's Roosevelt Hospital Center.
"The continuing redesign and modification of surgical procedures to relieve
outflow obstruction have corresponded to ideas about the cause of this
condition. In this review we discuss the evolution of surgical procedures to
relieve obstruction and review modern surgical approaches," the researchers
added.
"Medical and nonsurgical methods for reducing obstruction are reviewed, as
well as efforts to prevent sudden arrhythmic cardiac death. Echocardiography has
become central to understanding this complex phenomenon, and for clinical
diagnosis, operative planning and intraoperative management," the researchers
concluded.
Sherrid and colleagues published their study in the Annals of Thoracic
Surgery (Obstructive hypertrophic cardiomyopathy: Echocardiography,
pathophysiology, and the continuing evolution of surgery for obstruction. Ann
Thorac Surg, 2003;75(2):620-632).
