Introduction
Aortic valve disease (AVD) is the most common valvular heart disease in
developed countries which accounts for more than 50% of open-heart
surgeries in Europe.1,2 In Vietnam, AVD is also a
common valvular heart disease. Worldwide, aortic valve replacement
surgery using a prosthetic valve remains the standard method to treat
patients with aortic valve disease who have indications for
surgery.3 However, there are several limitations
related to a prosthetic valve, such as lifelong administration of
anticoagulants, premature degeneration of biological valve, and pannus
formation in sub-valvular area.4,5,6 Therefore, aortic
valve repair or reconstruction surgery has been increasingly considered.
Tuffier performed the first surgical commissurotomy of the aortic valve
in 1913.7 Since cardiopulmonary bypass was invented
and developed in 1954, many repair or reconstruction techniques have
been reported with favourable outcomes.8,9 One method
that has been applied in many countries with a plethora of successful
operations is Ozaki’s procedure.10 This technique
reconstructs individual cusps and was firstly performed in April 2007,
Tokyo, Japan.11 In Vietnam, aortic valve
reconstruction surgery has just been implemented recently with early
results of feasibility and advantages have been
reported.12,13 Therefore, we conducted this study with
02 objectives: (1) To evaluate the indications of aortic valve
reconstruction surgery by Ozaki’s procedure at our hospital, (2) To
report the mid-term outcomes of this method.
