Distal transradial access (dTRA) is a novel alternative to conventional radial artery access for coronary catheterization. However, the feasibility and safety of repeated use of dTRA have not been fully elucidated. This study aimed to evaluate the feasibility and safety of the repeated use of dTRA for coronary angiography and intervention in the same arm. A total of 1717 patients underwent angiography or angioplasty via dTRA. We retrospectively analyzed the catheterization records of patients wh...

BACKGROUND Drug-eluting stents (DESs) have been developed with thinner stent struts, and more biocompatible polymers and anti-proliferative drugs to improve the clinical performance. However, it remains unclear whether thinner struts are associated with favorable short- and long-term clinical outcomes such as target lesion revascularization (TLR), periprocedural myocardial infarction (PMI), and stent thrombosis (ST). METHODS We searched MEDLINE, Embase and other online sources for randomized con...

Measuring the effect of a treatment on outcomes is an important goal for research in pediatric/congenital interventional cardiology. The breadth of anatomic and physiologic variations, patient ages, and genetic syndromes and noncardiac comorbid conditions all represent sources of potential confounding and effect modification that are major obstacles to this goal. If not accounted for, these factors can obscure the "true" treatment effect and lead to spurious conclusions about the relative effica...

To compare 10-year outcomes after implantation of sirolimus-eluting stents (SES) versus paclitaxel-eluting stents (PES) for left main coronary artery (LMCA) stenosis. Very long-term outcome data of patients with LMCA disease treated with drug-eluting stents (DES) have not been well described. In 10-year extended follow-up of the MAINCOMPARE registry, we evaluated 778 patients with unprotected LMCA stenosis who were treated with SES (n = 607) or PES (n = 171) between January 2000 and June 2006. T...

Delayed coronary obstruction is a rare but often fatal complication of transcatheter aortic valve replacement that can present within 24 hr after the transcatheter aortic valve replacement procedure. We present a case of a 77-year-old woman whose distal left main coronary artery bifurcation became obstructed by an embolized piece of native valve leaflet material 16 hours after the uncomplicated transfemoral implantation of an Edwards Sapien Ultra 23 mm aortic valve, which was successfully treate...

OBJECTIVES The aim of this study was to investigate whether lipid core plaque (LCP) in the entire stented segment detected by near-infrared spectroscopy-intravascular ultrasound (NIRS-IVUS) could predict procedural myocardial infarction (PMI) in patients undergoing percutaneous coronary artery intervention (PCI). BACKGROUND NIRS-IVUS can identify LCP, described as high lipid core burden index (LCBI). Previously, the highest LCBI contained only in the 4-mm segment (maxLCBI4mm ) was reported to pr...

BACKGROUND Pulmonary hypertension (PH) is a marker of poor outcome in mitral stenosis (MS), which improves after percutaneous mitral valvuloplasty (PMV). However, mechanical interventions for relief of valve obstruction often but not always reduce pulmonary pressures. This study aimed to assess the parameters associated with abnormal pulmonary artery pressure (PAP) response immediately after a successful PMV, and also its impact on long-term outcome. METHODS A total of 181 patients undergoing PM...

Left main coronary artery atresia (LMCAA) is a rare congenital anomaly of the coronary artery that may have an unfavorable prognosis if left untreated. Surgical revascularization by either coronary artery bypass grafting or coronary reconstruction osteoplasty is unanimously recognized as the treatment of choice for this condition. Here, we first report a case of LMCAA treated with revascularization by percutaneous coronary intervention (PCI) through a retrograde approach. Intravascular ultrasoun...

BACKGROUND Transcatheter aortic valve replacement (TAVR) is being increasingly used for decompensated severe symptomatic aortic stenosis. Data on urgent and elective TAVR readmission is scarce in the literature. Here, we have performed a retrospective cohort study with the Nationwide Readmission Database of 2016 to identify the rate of 30-day all-cause readmission, common causes of readmission, and distribution of morbidity in index admission and readmission after urgent and elective TAVR. METHO...

OBJECTIVES To investigate whether the integrative echocardiographic criteria used in the cardiovascular outcomes assessment of the mitraclip percutaneous therapy (COAPT) for heart failure patients with functional mitral regurgitation study predict outcomes after edge-to-edge trancatheter mitral valve repair (TMVr) for the treatment of secondary mitral regurgitation (SMR). BACKGROUND Two randomized controlled trials comparing TMVr to medical treatment reported conflicting findings. Differences in...
