OBJECTIVES: We sought to examine contemporary perspectives and practices on chronic total occlusion (CTO) percutaneous coronary intervention (PCI). BACKGROUND: The frequency and success of CTO-PCI have been increasing in recent years. METHODS: An online questionnaire was created and distributed to cardiologists within the United States and internationally. RESULTS: A total of 1149 responses were obtained. The United States (n = 845; 73...

OBJECTIVES: Radiation dose was compared between two modern imaging systems with different x-ray tube technology (Megalix vs Gigalix) and detector type (amorphous vs crystalline silicon) at the same institution. BACKGROUND: Further reduction in radiation dose than currently reported may be achievable with advances in x-ray tube and detector technology. METHODS: Radiation dose (air kerma, dose-area product [DAP]) was retrospectively compared for post-transplant pediatric patients undergoing right heart catheterization/biopsy (fluoroscopy only) or "annual" catheterization with coronary angiography in one of two imaging systems between January 2014 and December 2016...

OBJECTIVES: This study was conducted to determine the association between radial access, guided femoral access, and non-guided femoral access on postprocedural bleeding and vascular complications after percutaneous coronary intervention (PCI). BACKGROUND: Bleeding events and major vascular complications after PCI are associated with increased morbidity, mortality, and cost. While the radial approach has been shown to be superior to the femoral approach in reducing bleeding and vascular complications, whether the use of micropuncture, fluoroscopy, or ultrasound mitigates these differences is unknown...

BACKGROUND: Most drug-eluting stent (DES) trials have excluded patients with chronic kidney disease (CKD). The efficacy of DES implantation in patients with CKD is therefore not known. OBJECTIVES: To evaluate the outcomes with DES vs bare-metal stent (BMS) implantation in patients with CKD. METHODS AND RESULTS: MEDLINE, EMBASE, and CENTRAL were searched for studies including at least 100 patients with CKD (estimated glomerular filtration rate ≤60 mL/min/1...

BACKGROUND: Movement of the stent delivery system in the coronary bed as a result of the cardiac cycle is a well-known clinical observation that usually is either underestimated or ignored. This effect may potentially jeopardize precise stent deployment. We used a novel technology to objectively measure the relative intracoronary device motion in the different coronary segments throughout the cardiac cycle. METHODS: A total of 193 patients undergoing coronary angiography were enrolled and their studies were analyzed for device movement using the SyncVision System (Philips Volcano)...

BACKGROUND: Despite widespread use, evidence to support preemptive intraaortic balloon pump (IABP) insertion for patients undergoing high-risk coronary artery bypass graft (CABG) surgery remains sparse, and in need of a well-defined clinical trial. To inform the design of a prospective trial, we sought to review outcomes in randomized controlled trials (RCTs) of anticipatory IABP use vs control in patients undergoing high-risk CABG through meta-analysis. The primary endpoint was all-cause mortality within 30 days of surgery...

BACKGROUND: Hemostasis following transradial access (TRA) is usually achieved by mechanical compression. We investigated use of the QuikClot Radial hemostasis pad (Z-Medica) compared with the TR Band (Terumo Medical) to shorten hemostasis after TRA. METHODS: Thirty patients undergoing TRA coronary angiography and/or percutaneous coronary intervention were randomized into three cohorts post TRA: 10 patients received mechanical compression with the TR Band, 10 patients received 30 min of compression with the QuikClot Radial pad, and 10 patients received 60 min of compression with the QuikClot Radial pad...

OBJECTIVES: To assess the predictive value of Pd/Pa after nitroglycerin administration (Pd/Pa[N]) as compared with standard fractional flow reserve (FFR). METHODS: Consecutive patients with intermediate coronary lesions assessed by FFR between January 2014 and October 2015 were included. We measured Pd/Pa at baseline, Pd/Pa(N), and Pd/Pa after incremental doses of intracoronary adenosine. RESULTS: A total of 134 patients (27% females; mean age, 65 years) were included...

Coronary angiography remains the gold standard for diagnosing obstructive coronary artery disease. However, no standardized, objective, and quantitative classification to assess the quality of coronary angiography exists. In the present report, we sought to establish a novel standardized quantitative classification for the quality of coronary angiography, taking into consideration two main parameters: coronary contrast filling and coronary sinus contrast reflux. Intraobserver and interobserver reproducibility performed among 70 angiograms and 9 readers demonstrated excellent and substantial reproducibility, respectively...

An 86-year-old female patient was referred for treatment of symptomatic severe aortic stenosis. The heart team decided to perform transfemoral transcatheter aortic valve implantation. A 25 mm transcatheter aortic valve was implanted, but the valve migrated low into the left ventricular outflow tract. The subsequent removal and replacement procedures are described.

We present a 75-year-old male with acute inferior ST-elevation myocardial infarction, severe coronary artery ectasia, and large thrombus burden in the right coronary artery to support the use of intracoronary thrombolysis as a second-line therapy for a large thrombus burden in primary percutaneous coronary intervention.

Aspiration thrombectomy was performed to retrieve intact thrombus in a 69-year-old woman. Bradycardia and hypotension rapidly resolved. Balloon angioplasty was performed at the site of proximal RCA in-stent restenosis with improved angiographic appearance and TIMI 3 flow in the major branches.

OBJECTIVE: We assess the angiographic and clinical outcomes of patients with a history of coronary artery bypass graft (CABG) surgery who underwent orbital atherectomy for the treatment of severely calcified coronary lesions. BACKGROUND: The presence of severe coronary artery calcification (CAC) increases the complexity of percutaneous coronary intervention (PCI) and is associated with worse clinical outcomes. Patients with a history of CABG who undergo PCI often have comorbidities and are at higher risk for ischemic complications...

AIMS: To investigate the influence of baseline thrombocytopenia (TCP) on short-term and long-term outcomes after transcatheter aortic valve replacement (TAVR). METHODS AND RESULTS: A total of 732 consecutive patients with severe, symptomatic aortic stenosis undergoing TAVR from January 2012 to December 2015 were included. Primary outcomes of interest were the relationship of baseline TCP with 30-day and 1-year all-cause mortality. Secondary outcomes of interest were procedural complications and in-hospital mortality in the same subgroups...

OBJECTIVES: The aim of this study was to assess the safety of the retrograde procedure with long-term follow-up of 86 patients after retrograde recanalization of the superficial femoral artery (SFA). BACKGROUND: Chronic total occlusion (CTO) of SFAs occurs in >50% of the patient population with peripheral artery disease. The retrograde technique is an option for patients with unsuccessful antegrade percutaneous interventions, but data from long-term follow-up after retrograde recanalization are still limited...

Discrete subaortic stenosis (DSS) is a progressive obstruction of left ventricular outflow tract (LVOT) resulting in the development of aortic regurgitation in its natural course. Hence, early intervention is recommended. Percutaneous balloon dilation of DSS has been reported and can substantially reduce LVOT pressure gradient. The response to balloon dilation of DSS is transient and may complicate with chordal or papillary muscle rupture. Hence, balloon dilation of DSS should be discouraged.

A 1-month-old, 2.4 kg infant, previously born at 32 weeks gestation, was found to have a murmur while in the neonatal intensive care unit. The patient had ongoing feeding intolerance and required supplemental oxygen via nasal cannula. Cardiac computed tomography showed discrete stenosis of the proximal left pulmonary artery (LPA) with a normal-sized distal LPA. We describe the treatment course with transcatheter coronary stent implantation.
