Percutaneous closure of mitral paravalvular leaks in patients with aortic valve prostheses.

3. itral, 33%) and cases of tricuspid endocarditis are rare (2%). This because of the anatomical relationship with the atrioventricular de, which is situated at the centre of Koch’s triangle, close to the ncoronary aortic leaflet and the anterior mitral leaflet; the icuspid septal leaflet, on the other hand, is located at the base of ch’s triangle. In a study of patients with endocarditis and mplete AVB, pathology workup revealed the presence of an fection, usually accompanied by abscesses and fistulas, that fected the conduction pathways; in cases involving paroxysmal B, inflammation was observed at this level, which would plain the reversibility of the event. Electrocardiographic onitoring is important in patients with endocarditis, as the pearance of conduction abnormalities can alert us to the pearance of perivalvular complications; similarly, once a nduction block has been detected, its disappearance in less an a week indicates a good response to antibiotic treatment. Right-sided endocarditis is an underdiagnosed condition, obably due to its atypical clinical presentation, although getations can be readily observed even by transthoracic hocardiography. The case described here is exceptional in at it involved isolated tricuspid endocarditis appearing with mplete AVB and left bundle-branch block that was reversed on treatment with antibiotics. Cases of conduction abnormales in association with tricuspid valve endocarditis have rarely en described in the literature, although there appears to be a ndency for the block to be reversed with medical treatment, 4.
