AbstractMesothelial/monocytic incidental cardiac excrescence (MICE) is a rare benign finding made of mesothelial cells, histiocytes, and fibrin, usually found during heart valve surgery. The clinical relevance resides in the potential misdiagnosis as metastatic carcinoma or arterial embolism. The pathogenesis remains uncertain, with artifactual and reactive hypotheses. Here we present a case of MICE with paradigmatic clinical, imaging, and histological features in a 28 ‐year‐old woman with undifferentiated connective tissue disease without previous cardiac catheterization with possible pathogenesis, highlighting the im...

We report on three cases of acute coronary complications of different valvular surgical procedures diagnosed and treated in the cardiac catheterization laboratory. Intracoronary optical coherence tomography was used to identify the cause of coronary flow impairment and provided important insights on the mechanism of intra-operative vascular damage.

AbstractObjectivesTo investigate the impact of the introduction of the next generation self ‐expanding (SE) and balloon‐expandable (BE) transcatheter heart valves (THVs) on the incidence of prosthesis–patient mismatch (PPM) after transcatheter aortic valve replacement (TAVR).BackgroundPPM is a risk factor for accelerated degeneration of bioprosthetic aortic valves. Data on PPM after TAVR are derived mainly from studies of older generation THVs.MethodsPPM was assessed at 30  days post‐TAVR with the older generation (Medtronic CoreValve, n = 120 and Edwards Sapien XT, n = 121) a...

Use of the ClearSight® System for Continuous Noninvasive Hemodynamic Monitoring during Heart Valve Interventions: Review of the Literature and Single-Site Experience. Heart Surg Forum. 2018 Nov 14;21(6):E476-E483 Authors: Gellert G, Bramlage P Abstract During interventional and structural cardiology procedures, such as mitral valve (MitraClip, BMV), aortic valve (TAVR, BAV), tricuspid valve (MitraClip), left atrial appendage (Watchman, Lariat), atrial septum (ASD/PFO closure), and coronary artery intervention (high-risk PCI), among others, patients are at a high risk of hemodynamic instability and...

Abstract Current balloon expandable transcatheter valves have limited applicability to patients with “native” right ventricular outflow tracts (RVOT), meaning those who have had previous surgery and are left with large, compliant, irregular RVOT. The Alterra Adaptive PrestentTM is a self‐expanding, partially covered stent that was designed to internally reconfigure these types of RVOT, making them suitable for implantation of a commercially available balloon expandable heart valve, the SAPIEN 3. Herein, we describe the first human implant of this device.

ConclusionBPD was performed in 39% of patients who received a SE‐THV, and was successful in the majority of attempts. BPD failure was more likely in patients with a small postdilatation balloon‐to‐annulus diameter ratio. Effective BPD improved THV hemodynamic performance, and this was maintained in the intermediate‐term post‐TAVI.

ConclusionsA supra‐annular structure based sizing strategy is feasible for TAVR in patients with bicuspid AS.
