Transcatheter aortic valve implantation (TAVI) has shown favorable outcomes in patients with severe symptomatic aortic valve stenosis who are at high surgical risk or are unsuitable candidates for open heart surgery. However, concerns exist over treating patients who have previously undergone mitral valve surgery due to the potential interference between the mitral prosthetic valve or ring and the TAVI device. In this case report, we present a patient with symptomatic severe aortic stenosis and previous mechanical mitral valve replacement who was successfully treated with TAVI using a CoreValve.

Age-related degenerative calcification is currently the most common cause of aortic stenosis (AS) in adults and the most frequent reason for aortic valve replacement in patients with AS. With the increased life expectancy, a large proportion of elderly patients with AS is undergoing cardiac surgery, although many are not offered conventional aortic valve replacement due to the risks involved. However, sutureless aortic valve replacement provides an alternative for this group of elderly patients. This case series reports the first experience in Asia of sutureless aortic valve implantation in seven patients at our institution.

OBJECTIVETo determine whether the prosthesis-patient mismatch has a deleterious impact on survival after mitral valve replacement.

DATA SOURCESA comprehensive literature search of PubMed, Embase, and ScienceDirect was carried out. References and cited papers of relevant articles were also checked.

STUDY SELECTIONAll articles published after January 1980 was initially considered. Non-English and non-human studies, case reports, and reviews were excluded from the initial search. References and cited papers of relevant articles were also checked.

RESULTSA total of 8 retrospective cohort studies were identified for this review. The overall incidence of prosthesis-patient mismatch (<1.3 to <1.2 cm(2)/m(2)) after mitral valve replacement ranged from 3.7% to 85.9% (moderate prosthesis-patient mismatch (0.9 to 1.2 cm(2)/m(2)) in 37.4% to 69.5%, severe prosthesis-patient mismatch (<0.9 cm(2)/m(2)) in 8.7% to 16.4%). Four studies demonstrated an association of prosthesis-patient mismatch with reduced long-term survival, but the other four studies found no significant deleterious impact of prosthesis-patient mismatch after mitral valve replacement. No definite conclusion could be derived from these conflicting results.

CONCLUSIONSCurrent evidence is insufficient to derive a definite conclusion whether mitral prosthesis-patient mismatch affects long-term survival because of the biases and confounding factors that interfere with late clinical outcomes. Goodquality prospective studies are warranted to evaluate the impact of mitral prosthesis-patient mismatch after mitral valve replacement in the future.
