Correspondence: *Héctor Hugo Escutia-Cuevas E-mail: perseoyarista@hotmail.com Available online: 19-03-2019 Arch Cardiol Mex. 2019;89(1):88-91 www.archivoscardiologia.com Date of reception: 12-07-2018 Date of acceptance: 29-08-2018 DOI: 10.24875/ACM.M198 Paravalvular leak (PVL) is a common and challenging problem that has existed since prosthetic cardiac valves were first implanted. PVL occurs in 7-17% of mitral valve replacements (MVRs) and 5-10% of aortic valve replacements (AVRs)1 and can be associated with disabling symptoms related to heart failure or hemolysis2. Repeat surgery to repair PVL is associated with significant mortality and morbidity3. Tissues around PVL are often calcified and friable, and therefore, leaks may recur4. Conservative management of mild-to-moderate leaks is also associated with high adverse event rates because leaks tend to deteriorate over time5. Despite the varied morphologies of PVLs, it is clear from all the series that oblong devices are preferentially selected by implanting cardiologists for closing PVLs in all the countries6. Due to the lack of specifically designed devices for PVL (mitral and aortic) in México, we report on the first use in our country of such a device in two patients with PVL.
