A 67-year-old man was admitted to our hospital due to chest tightness induced by activity that had started about 2 months earlier. To clarify the causes of chest pain in this patient, cardiac magnetic resonance imaging was performed, resulting in a d…
A novel technique was used to eliminate the guidewire shadow artifact by removing the guidewire in frequent domain optical coherence tomography interpretation in vivo. This technique allowed us to observe a rare iatrogenic spiral dissection of the ra…
We observed left ventricular microbubbles associated with Impella support in the setting of a high-risk coronary intervention. Left ventricular microbubbles may indicate exaggerated shear stress and cavitation phenomenon, potentially leading to hemol…
Coronary angiography demonstrated severe distal LM disease in a patient with heavy concentric calcification extending into the LAD and left circumflex arteries. Rotational atherectomy and lithotripsy were used to debulk plaque so that stenting could…
High-grade and complete heart block commonly occurs in adult patients with restrictive cardiomyopathy, and requires aggressive monitoring and prophylactic pacemaker/defibrillator. There are limited data on the procedural details of pacemaker implanta…
J INVASIVE CARDIOL 2020;32(4):E97. Key words: cardiac imaging, stent deformity, stent-in-stent implantation A 62-year-old male with a history of previous mid left anterior descending (LAD) percutaneous coronary intervention (PCI) in 2012 presented…
Abstract: Background. Despite a range of devices, medical interventions, and revascularization techniques utilized in cardiogenic shock (CS), there is a lack of evidence guiding management. We sought to characterize the contemporary trials through ut…
Our healthcare systems are facing unprecedented pressure to come up with innovative solutions to help combat coronavirus disease 2019.
We believe there was a fundamental problem in the algorithm used to detect ischemia with initial non-invasive stress testing in the recently published ISCHEMIA trial. In this editorial, we discuss some of the limitations involved with the trial desig…
