BACKGROUND: Although first-generation drug-eluting stent (DES) devices have effectively achieved their main goal of reducing restenosis, their safety has been limited by suboptimal polymer biocompatibility, delayed stent endothelialization, and local drug toxicity, which ultimately prompted the development of new-generation DES options carrying biocompatible or even biodegradable polymers. AIMS: We sought to assess the vessel-healing pattern of the novel sirolimus-eluting Inspiron DES (Scitech Medical) using serial optical coherence tomography (OCT) and assuming the hypothesis that this thin-strut (75-μm), biodegradable-polymer DES promotes a faster healing, with very early strut coverage...

BACKGROUND: Early graft failure (EGF) after coronary artery bypass grafting (CABG) occurs in up to 12% of grafts, but is often clinically unapparent. EGF may result in perioperative myocardial infarction with consequently increased mortality. The aim of the present study was to analyze the incidence of clinically apparent EGF in patients undergoing CABG and the influence on mortality. METHODS: We analyzed outcomes of consecutive patients undergoing CABG from January 2015 to December 2018 with respect to postoperative emergency coronary angiography (CAG) due to suspected EGF and 30-day mortality...

BACKGROUND: Palpation-guided access of the radial artery (RA) has transradial access (TRA) failure rates averaging 6%-7%. This study aimed to measure RA and ulnar artery (UA) diameters by ultrasound in a typical American population, in hopes of elucidating data that may improve TRA success rates. METHODS: Intraprocedural ultrasound measurements of the RA and UA in 565 consecutive patients undergoing TRA were retrospectively analyzed. RESULTS: The RA is usually larger than the UA, with diameters of 3...

INTRODUCTION: Data regarding the prevalence of carotid artery stenosis (CAS) in patients undergoing transcatheter aortic valve implantation (TAVI) are scarce. Whether CAS, especially severe or bilateral, is a predictor of worse prognosis after TAVI is unknown. We aimed to address these questions. METHODS: We included all patients who underwent TAVI between 2018 and 2021. Using pre-TAVI carotid Doppler ultrasound, atherosclerosis of the right and left carotid internal arteries was assessed...

BACKGROUND: Severe coronary artery calcification (CAC) remains challenging during percutaneous coronary intervention (PCI) and often requires 1 or more advanced calcium modification tools. OBJECTIVES: We describe the combination use of rotational (RA) or orbital atherectomy (OA), with intravascular lithotripsy (IVL), termed rotatripsy and orbital-tripsy, respectively, for modifying CAC prior to stent implantation during PCI. METHODS: We performed a retrospective analysis of patients treated with rotatripsy or orbital-tripsy at our center between July 2019 and March 2022...

Although high body mass index (BMI) is a known risk factor for the development of cardiovascular diseases, people who are overweight or obese often have better outcomes after cardiac procedures. Whether this "obesity paradox" is observed in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is unknown. Therefore, we examined the association of BMI with the outcomes of CTO-PCI in patients from the large, multicenter PROGRESS-CTO registry after stratifying patients into 3 BMI groups.

BACKGROUND: Disparities between thermodilution (TD) and Fick measurements of cardiac index (CI) are common in real-world clinical practice. Published studies about the effect of tricuspid regurgitation (TR) on TD are small and describe conflicting results. We tested the correlation between TD and Fick across a wide range of TR severity, in a larger group of patients undergoing right heart catheterization (RHC). We aimed to determine if TD is an acceptable alternative to Fick in patients with TR in clinical practice...

A complex 15-year treatment history of a 75-year-old man with New York Heart Association class III symptoms is presented via images and video. His treatment history was noteworthy of bicuspid aortic valve (AV) and a ventricular septal defect (VSD), for which he had an AV replacement and VSD closure in 2005. In 2015, he underwent redo AV replacement and root reconstruction. Echocardiography demonstrated severe bioprosthetic AV stenosis and moderate AV regurgitation. Valve-in-valve transcatheter aortic valve replacement with a Sentinel cerebral protection device was recommended...

Left atrial appendage (LAA) occlusion has emerged as an al- ternative to oral anticoagulation in non-valvular atrial fibril- lation. The success rate is high, but we are still facing some challenging LAA anatomies that may increase the risk of sub- optimal results. These images show that the Amplatzer steer- able sheath is useful for LAA occlusion, especially in cases with challenging anatomies. Small variations of the distal end angle can improve the success rate and reduce complications.

When dislodged stents remain on the coronary wire, the wire can be snared outside of the body (presnaring), and the snare loop advanced over the wire into the body to retrieve the stent. Presnaring may be a valuable technique to retrieve dislodged coronary stents when the stent remains on the coronary wire, as demonstrated in the 2 patients described.

In this clinical image vignette, we illustrate the presentation and management of an extremely rare and lethal complica- tion of radial access percutaneous coronary intervention. We present a case of perforation of a small collateral branch of the brachiocephalic artery with subsequent mediastinal hematoma formation and stridor presentation. We suspect the perforation was probably caused by the hydrophilic-coated guidewire. After a multidisciplinary heart team discussion, a percutaneous approach was recommended...

Absorb bioresorbable vascular scaffolds were designed to overcome the limitations imposed by drug-eluting stents; however, the Absorb BVS showed a 2% very late thrombosis rate. Suboptimal implantation technique has been proposed as a mechanism for the higher BVS thrombosis rate; one posthoc analysis suggested adequate pre- and postdilation in addition to proper sizing could reduce BVS thrombosis rates by 70%. This case acts as a proof of concept demonstrating advantages of BVS, namely, the ability to image the target vessel non-invasively and revascularize percutaneously or surgically if required...

The authors comment on certain points of the Akhar article from the April 2022 issue of the JIC. In their letter, they differentiate between chronic total occlusions and functional occlusions and discuss spontaneous recanalizations and the appearance of multiple intraluminal channels.They question whether the thrombotic occlusion of the right coronary artery was because of atherothrombosis or thromboembolism of both the right coronary artery and pulmonary circulation. The authors also mention that the index case needs a detailed evaluation of the hypercoagulable state to explain thrombosis of both the pulmonary and coronary circulation...

An 86-year-old patient with non-valvular atrial fibrillation was referred to our institution to undergo a left atrial appendage (LAA) closure for recurrent gastrointestinal bleeding on direct oral anticoagulants. The transesophageal echocardiogram (TEE) performed the previous day evaluated the morphology and dimensions of the LAA and ruled out any thrombus. During the procedure, a pigtail catheter was inserted into the LAA, observing an unusual image we describe as a culde- sac, without an anomalous connection with any drainage in other vessel or cavity...
