The current iterations of balloon-expandable transcatheter aortic valve replacement (TAVR) valves consist of a maximum size of 29 mm, corresponding to maximum annulus area of 680 mm2 . However, a number of patients who qualify for TAVR based on surgical risk may have anatomical features outside the FDA-approved descriptions. The technique of overexpansion of TAVR valves during deployment allows for more patients to be treated successfully. This particular case demonstrates that overexpansion is safe and efficacious in a very large annulus of >800 mm2 ...

A common clinical dilemma regarding treatment of patients with a mechanical valve is the need for concomitant antiplatelet therapy for a variety of reasons, referred to as triple therapy. Triple therapy is when a patient is prescribed aspirin, a P2Y12 antagonist, and an oral anticoagulant. Based on the totality of the available evidence, best practice in 2017 for patients with mechanical valves undergoing percutaneous coronary intervention (PCI) is unclear. Furthermore, the optimal duration of dual antiplatelet therapy after PCI is evolving...

The impact of predilatation (Pre-Dil) on prosthesis hemodynamics and clinical outcomes of subjects who underwent transcatheter aortic valve implantation (TAVI) with a self-expanding prosthesis remains unclear. Two thousand seven hundred twenty-one subjects from the extreme- and high-risk CoreValve Continued Access Study (CAS) were included in the analysis. Subjects who underwent Pre-Dil before TAVI were compared with subjects who underwent TAVI without Pre-Dil. Clinical outcomes included death, stroke, myocardial infarction, acute kidney injury, and new permanent pacemaker implantation...

PURPOSE: Evaluate the safety of MynxGrip® for common femoral vein closure. METHODS AND MATERIALS: This is a multicenter, randomized, prospective study of 208 patients who were slated to undergo diagnostic/interventional procedures via femoral venous access. Patients were randomized 1:1 to receive venous hemostasis via MynxGrip® (n = 104) or manual compression (n = 104) utilizing 5, 6, and 7 Fr sheaths. Bilateral calf and thigh circumferences were measured serially...

Drug-eluting stents (DES) significantly reduced the incidence of in-stent restenosis (ISR). However, ISR still exists in the contemporary DES era. Previously deemed to be a benign process, ISR leads to complex presentation and intervention. This study aimed to compare the presentation and outcome of DES-ISR versus de novo lesions. We performed a retrospective analysis of 11,666 patients receiving percutaneous coronary intervention from 2003 to 2017 and divided them into 2 groups by de novo stenosis and ISR...

OBJECTIVES: This study sought to develop a novel technique called bioprosthetic or native aortic scallop intentional laceration to prevent coronary artery obstruction (BASILICA). BACKGROUND: Coronary artery obstruction is a rare but fatal complication of transcatheter aortic valve replacement (TAVR). METHODS: We lacerated pericardial leaflets in vitro using catheter electrosurgery, and tested leaflet splaying after benchtop TAVR. The procedure was tested in swine...

Coronary angiography and percutaneous coronary intervention using the radial approach are becoming more frequent. Pronounced guide catheter manipulation in cases with tortuous access routes may lead to severe catheter kinking or knotting. The purpose of this review article is to present several techniques to resolve radial access catheter knots and kinks. First, simple maneuvers such as gentle traction, rotation, and guidewire advancement can often resolve minor kinking; however, complex loops and kinks are often not reversible with these simple maneuvers...

Permanent pacemaker (PPM) implantation remains common after transcatheter aortic valve implantation (TAVI). Invasive electrophysiology studies (EPSs) may reduce PPM implantation rates by identifying patients who do not require long-term pacing. At our institution, a new strategy in which patients with equivocal indications for pacing underwent EPSs to determine the need for PPM implantation was adopted. We compared baseline demographics, TAVI procedural details, and outcomes in patients without any conduction disturbance after TAVI, patients with new PPM implantation, and patients with EPS ± new PPM implantation...

Hemodynamic recording during interventional cardiovascular procedures is essential for procedural guidance, monitoring patient status, and collection of diagnostic information. Recent advances have made interventions guided by magnetic resonance imaging (MRI) possible and attractive in certain clinical scenarios. However, in the MRI environment, electromagnetic interference (EMI) can cause severe distortions and artifacts in acquired hemodynamic waveforms. The primary aim of this paper was to develop and validate a system to minimize EMI on electrocardiogram (ECG) and invasive blood pressure (IBP) signals...

BACKGROUND: Whole blood and red blood cell (RBC) donors are at risk of iron deficiency. Since Source plasma (SP) donors have RBCs returned during apheresis, risk of iron depletion appears low. However, SP donors can donate frequently and assessment of frequent donor iron status is needed. STUDY DESIGN AND METHODS: A total of 1254 SP donors were enrolled in four frequency groups determined by donations in the prior 12 months: no donations and 1 to 24, 25 to 69, and 70 or more donations...

Millisecond pulsars (MSPs) are old neutron stars that spin hundreds of times per second and appear to pulsate as their emission beams cross our line of sight. To date, radio pulsations have been detected from all rotation-powered MSPs. In an attempt to discover radio-quiet gamma-ray MSPs, we used the aggregated power from the computers of tens of thousands of volunteers participating in the Einstein@Home distributed computing project to search for pulsations from unidentified gamma-ray sources in Fermi Large Area Telescope data...

We aimed to compare the safety and efficacy of rotational atherectomy (RA) and orbital atherectomy (OA) during percutaneous coronary intervention in an all-comer population with severely calcified lesions. We included all patients who underwent percutaneous coronary intervention with OA or RA in our institution from October 2013 until October 2016. Comparison of baseline and procedural characteristics, along with acute complication rates and postprocedural cardiac enzyme elevation, was performed. There were 191 RA and 57 OA patients...

Society of Thoracic Surgeons (STS) score and frailty index are calculated routinely as part of transcatheter aortic valve implantation (TAVI) assessment to determine procedure risk. We aim to evaluate the incremental improvement of STS risk score using frailty status in predicting short- and long-term outcome after TAVI. Study population included 544 consecutive TAVI patients who completed full frailty assessment and STS score calculation before the procedure. Frailty is defined by the presence of any 3 of the following 5 criteria: algorithm-defined grip strength and 15-foot walking tests, body mass index < 20 kg/m2 , Katz activity of daily living ≤ 4/6, serum albumin < 3...

BACKGROUND: Clinical indications for transcatheter aortic valve replacement (TAVR) and elements of the implantation procedure, including delivery system miniaturization and novel access options, have evolved over time. The reasons patients are excluded from TAVR also have changed. The impact of these changes on patient referral for and exclusion from TAVR is unknown. METHODS: We retrospectively analyzed patients referred to our center for TAVR from January 2010 to August 2016 to evaluate reasons for patient exclusion...

OBJECTIVES: Pledget-assisted suture tricuspid valve annuloplasty (PASTA) is a novel technique using marketed equipment to deliver percutaneous trans-annular sutures to create a double-orifice tricuspid valve. BACKGROUND: Tricuspid regurgitation is a malignant disease with high surgical mortality and no commercially available transcatheter solution in the US.

Axillary arteries are less calcified and tortuous than iliofemoral arteries Axillary artery minimal luminal diameters are usually >5.0 mm even in patients with iliofemoral artery diameters < 5.0 mm Axillary and transcaval access are the only non-surgical fully percutaneous options for large-bore arterial access for TAVR or mechanical circulatory support devices.
