In this prospective multicenter trial of chest pain patients without known CAD, 64-multidetector row CCTA possesses high diagnostic accuracy for detection of obstructive coronary stenosis at both thresholds of 50% and 70% stenosis. Importantly, the 99% negative predictive value at the patient and vessel level establishes CCTA as an effective noninvasive alternative to ICA to rule out obstructive coronary artery stenosis.

The results indicate that postoperative incarcerated hiatal hernia after RE is an infrequently reported, albeit serious, complication. A preexisting hiatal hernia may put patients at a higher risk of incarceration. According to the authors' experience, a primary closure and reinforcement with mesh sutured to the gastric wall is recommended as a preventive measure. Diligent follow-up evaluation with regular computed tomography (CT) scans investigating likelihoods for incarceration is advisable, especially for patients with preexisting hernias.
