Since the inception of transcatheter aortic valve replacement (TAVR), there have been significant reductions in complications due to improvements of transcatheter heart valve (THV) designs and technologies. Given expanding TAVR applications, reducing complications further and better understanding THV durability has become a focus within the structural heart space. Recently, dedicated cardiac computed tomographic angiography (CTA) performed at 1 month post-TAVR has identified subclinical leaflet thrombosis (SLT), with rates as high as 40%...

BACKGROUND: Bioprosthetic (BP) valves have been increasingly used for aortic valve replacement over the last decade. Due to their limited durability, patients presenting with failed BP valves are rising. Valve in Valve - Transcatheter Aortic Valve Implantation (ViV-TAVI) emerged as an alternative to the gold standard redo-Surgical Aortic Valve Replacement (redo-SAVR). However, the utility of ViV-TAVI is poorly understood. METHODS: A systematic electronic search of the scientific literature was done in PubMed, EMBASE, SCOPUS, Google Scholar, and ClinicalTrials...

BACKGROUND: The concomitant presence of mitral stenosis (MS) in the setting of symptomatic aortic stenosis represent a clinical challenge. Little is known regarding the outcome of mitral stenosis (MS) patients undergoing transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR). Therefore, we sought to study the outcome of MS patients undergoing aortic valve replacement (AVR). METHOD: Using weighted data from the National Inpatient Sample (NIS) database between 2011 and 2014, we identified patients who were diagnosed with MS...

BACKGROUND: The successful recanalization rate of chronic total occlusion (CTO) lesions without retrograde collaterals available is always low. Intravascular ultrasound (IVUS) may be useful to guide the subintimal guidewire to re-enter the true lumen. We evaluated the clinical feasibility and efficacy of the IVUS-guided wiring re-entry technique for these complex CTO lesions. METHODS: Twenty consecutive patients (19 male, mean age: 65.3 ± 12.8 years) with both failed antegrade and retrograde approaches were enrolled...

OBJECTIVES: The PRISON-IV trial showed inferior outcome in patients with chronic total occlusions (CTOs) treated with the ultrathin-struts (60 μm for stent diameter ≤3 mm, 81μm >3 mm) hybrid-sirolimus eluting stents (SES) compared with everolimus eluting stents (EES, 81 μm). The aim of this study is to investigate if the use of smaller stents (≤3 mm) was responsible for the inferior outcome reported in the trial. METHODS: In the PRISON-IV trial 330 patients with CTO lesion were randomized 1:1 to receive either hybrid-SES or EES...

INTRODUCTION: Both resting and hyperemic physiologic methods to guide coronary revascularization improve cardiovascular outcomes compared with angiographic guidance alone. Fractional flow reserve (FFR) remains underutilized due to concerns regarding hyperemia, prompting study of resting distal to aortic coronary pressure (Pd/Pa). Pd/Pa is a vasodilator-free resting index unlike FFR. While Pd/Pa is similar to another resting index, instantaneous wave-free ratio (iFR), it is a whole-cycle measurement not limited to the wave-free diastolic period...

BACKGROUND: Because of the challenges in treating calcified coronary artery disease (CAD), lesion preparation has become increasingly important prior to percutaneous coronary intervention (PCI). Despite growing data for both rotational atherectomy (RA) and orbital atherectomy (OA), there have been no multicenter studies comparing the safety and efficacy of both. We sought to examine the clinical outcomes of patients with calcified CAD who underwent atherectomy. METHODS: A total of 39 870 patients from five tertiary care hospitals who had PCI from January 2011 to January 2017 were identified...

BACKGROUND: Device embolization is the most frequent procedural complication during transcatheter closure of congenital cardiac defects. Retrieval of an embolized device may often be complicated by failure to introduce the right atrial (RA) disk hub into the sheath or difficulty in securely grasping the hub pin of RA disk. We aimed to evaluate the efficiency and success rate of device retrieval using a novel double snare technique. METHODS: We reviewed retrieval procedures of embolized atrial septal defect (ASD) or left atrial appendage (LAA) occluder using double snare technique reported from five tertiary referral centers in Korea, Japan, and Uzbekistan...

OBJECTIVES: To evaluate the outcomes of rotational atherectomy for heavily-calcified side branches of coronary bifurcation lesions. BACKGROUND: Side-branch (SB) preservation is clinically important but technically challenging in heavily-calcified non-left main true bifurcation lesions. SB rotational atherectomy (SB RA) is sometimes mandatory but the clinical outcomes are not well studied. METHODS: We retrospectively studied the outcomes of patients who underwent RA at our institute for heavily calcified, balloon-uncrossable or-undilatable SB lesions over an approximately 5-year period (January 2011 to September 2016)...

BACKGROUND: Due the wide variability of left atrial appendage morphology left atrial appendage occlusion (LAAO) remains a challenging procedure. The steerable FuStar delivery sheath was designed to allow both, transseptal access and delivery of percutaneous devices. We here report the first-in-human experience of LAAO with the FuStar sheath. METHODS: Twenty patients (76.6 ± 8.4 years; 12 (60%) males; CHA2 DS2 -VASc score: 5.0 ± 2) with non-valvular fibrillation and contraindications to oral anticoagulation underwent LAAO with the LAmbre device using the FuStar steerable sheath (Lifetech Scientific Corp...

BACKGROUND: Right ventricular (RV) failure due to pulmonary embolism (PE) increases morbidity and mortality and contributes to prolonged hospital length of stay and higher costs of care. RV mechanical circulatory support (MCS) including Impella RP devices have been increasingly used in hemodynamically compromised PE patients who are refractory to intravascular volume expansion and inotropic therapy. However, effectiveness and safety of Impella RP, in hemodynamically unstable PE patients is unknown...
