Introduction
During the past two decades, major advances have
occurred in diagnostic techniques, the understand-
ing of natural history, and interventional cardiology
and surgical procedures for patients with valvular
heart disease. These advances have resulted in
enhanced diagnosis, more scientifi c selection of
patients for surgery or catheter-based intervention
versus medical management, and increased survival
of patients with these disorders. The information
base from which to make clinical management deci-
sions has greatly expanded in recent years, yet in
many situations, management issues remain contro-
versial or uncertain. Unlike many other forms of
cardiovascular disease, there is a scarcity of large-
scale multicenter trials addressing the diagnosis and
treatment of patients with valvular disease from
which to derive defi nitive conclusions, and the
information available in the literature represents
primarily the experiences reported by single institu-
tions in relatively small numbers of patients.
