Treatment-Relevant Findings in Transesophageal Echocardiography After Stroke: A Prospective Multicenter Cohort Study.

Background And Purpose: Cardiac ultrasound to identify sources of cardioembolism is part of the diagnostic workup of acute ischemic stroke. Recommendations on whether transesophageal echocardiography (TEE) should be performed in addition to transthoracic echocardiography (TTE) are controversial. We aimed to determine the incremental diagnostic yield of TEE in addition to TTE in patients with acute ischemic stroke with undetermined cause.

Tricuspid regurgitation is a predictor of mortality after percutaneous mitral valve edge-to-edge repair.

Aims: The aim of this study was to determine the impact of tricuspid regurgitation (TR) on mortality after edge-to-edge percutaneous mitral valve repair (PMVR), and also to analyse whether there is a difference in outcome between patients with improvement of TR after PMVR compared to patients without.

Methods And Results: Out of 197 consecutive patients who underwent PMVR, 139 patients with available follow-up (mean 428±386 days) were included in the study. Concomitant moderate/severe TR was present in 58.

First-in-human transcatheter tricuspid valve repair in a patient with severely regurgitant tricuspid valve.

Background: Severe tricuspid regurgitation is associated with poor prognosis; however, there are limited Class I indications for intervention, and high-surgical risk patients may go untreated. We report the first-in-human successful transcatheter tricuspid valve repair for severe tricuspid regurgitation.

Objectives: The objective of this study was to show the feasibility of a transcatheter tricuspid annular repair.

Comparison of quantitative coronary angiography and first-pass perfusion magnetic resonance imaging for the detection of an impaired coronary perfusion in nonsevere coronary stenosis.

Purpose: To compare quantitative coronary angiography (QCA) and first-pass perfusion magnetic resonance imaging (FPP-MRI) in symptomatic patients with nonsevere coronary stenosis to detect a reduced coronary flow velocity reserve (CFVR).

Materials And Methods: In 35 patients, FPP-MRI and CFVR measurements were performed in 40 coronary arteries with a diameter stenosis (DS) <70% by QCA. From FPP-MRI a myocardial perfusion reserve index (MPRI) was calculated.

Contrast-enhanced cardiac MR imaging in the detection of reduced coronary flow velocity reserve.

Purpose: To prospectively evaluate the accuracy of contrast material-enhanced cardiac magnetic resonance (MR) imaging for determining impaired coronary flow velocity reserve (CFR) by using Doppler flow measurement as the reference standard.

Materials And Methods: The study was approved by the institutional ethics committee, and all patients gave written informed consent. Eligible patients underwent contrast-enhanced cardiac MR imaging and invasive measurement of CFR.
