"A Bridge-over-the Bar": A Novel Strategy to Prevent Paravalvular Regurgitation during Mitral Valve Replacement for Severe Mitral Annular Calcifications.

Mitral annular calcifications have been known to increase complexity during mitral valve replacement (MVR). Standard procedure requires decalcification followed by reconstruction of the mitral annulus prior to placing the prosthesis. While this is the ideal technique, it is not feasible in every patient due to the associated risks.

Outcome of Patients Having Transcatheter Mitral Valve Implantation for the Treatment of Degenerated Mitral Bioprostheses.

Transcatheter mitral valve implantation (TMVI) is at various levels of preclinical investigation and has proven to be more challenging than transcatheter aortic valve implantation due to more complex anatomy. The purpose of this study is to evaluate the short-term and long-term outcomes of high-risk patients who underwent TMVI for degenerated mitral bioprostheses. In this retrospective, observational study, we reviewed data on the first 26 patients with previous surgical mitral valve replacement or repair with annular ring that underwent TMVI using the balloon-expandable heart-valve system at our institution from 2014 to 2019.

Prognostic Implications of Baseline B-type Natriuretic Peptide in Patients Undergoing Transcatheter Aortic Valve Implantation.

B-type natriuretic peptide (BNP) levels have been shown to predict outcomes in surgical aortic valve replacement patients. BNP levels have not been well studied in patients undergoing transcatheter aortic valve implantation (TAVI). The purpose of this study is to define the utility of baseline BNP levels in predicting short-term outcomes after TAVI.

Middle Aortic Syndrome in a Child-Bearing Age Patient.

We report a rare case of a 30-year-old female who had a long-standing history of middle aortic syndrome that was being managed nonsurgically. She presented with hypertension and buttock pain with plans to become pregnant. She underwent an aortoiliac bypass.
