BACKGROUND: The superiority of drug-eluting stent (DES) implantation over bare-metal stent (BMS) implantation in saphenous vein graft (SVG) lesions is controversial, with significant heterogeneity demonstrated in the literature. METHODS: A study search was conducted from January 2003 to October 2015, and identified four randomized controlled trials (RCTs) and 35 observational studies comparing DES vs BMS in SVG interventions. Clinical endpoint data were abstracted and analyzed by combining the odds ratios (ORs) of individual studies into a pooled OR using a random-effects model...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has become the standard therapy for patients with severe symptomatic aortic stenosis and unacceptable high risk for surgical aortic valve replacement. Several different devices for TAVR have been introduced so far, each of them with unique features. AIMS: To analyze our first real-world experience with the second- generation, mechanically expanded, fully repositionable transfemoral Lotus TAVR device (Boston Scientific)...

BACKGROUND: Rates and importance of periprocedural myocardial injury (PMI) after crossing coronary chronic total occlusions (CTOs) is not well understood. This study sought to investigate long-term clinical implications of PMI in patients undergoing percutaneous coronary intervention (PCI) for single CTO utilizing antegrade technique. METHODS: Out of 11,957 patients undergoing non-urgent PCI, a total of 1110 patients with symptomatic angina and single CTO were treated by antegrade PCI and observed for up to 10 years...

OBJECTIVES: CENTRAL was a prospective, multicenter, 100 patient study designed to evaluate the ability of a recanalization catheter system to cross chronic total occlusions (CTOs) of the superficial femoral artery while staying within the central vessel lumen. METHODS: The primary endpoint was the successful crossing of a CTO (≥90% of the length) with the recanalization catheter in the central lumen of the superficial femoral artery in at least one-half of the studied patient population, confirmed by intravascular ultrasound...

BACKGROUND: We sought to compare long-term mortality and quality of life (QoL) in very elderly (≥80 years) patients undergoing transcatheter aortic valve implantation (TAVI) in comparison with younger patients (<80 years). METHODS: A total of 101 patients treated with TAVI were divided into two groups according to age: <80 years (n = 42; 41.6%) and ≥80 years (n = 59; 58.4%). The baseline characteristics, including procedural outcomes as well as frailty and QoL assessment were compared between age groups...

OBJECTIVE: We investigated whether successful revascularization of total occlusion of a large lower-extremity artery is associated with improvement of left ventricular (LV) diastolic function. BACKGROUND: Total occlusion of a large lower-extremity artery might affect the systemic vascular resistance and increase the afterload, because the left ventricle must work harder to eject blood into a smaller vascular bed. Chronic elevation of afterload is a cause of LV diastolic dysfunction...

OBJECTIVES: Periprocedural bleedings, often related to vascular access site, represent an important drawback of percutaneous coronary procedures and are associated with worse outcomes. Radial access (RA) and, potentially, femoral access (FA) with vascular closure device (VCD) are useful strategies in order to mitigate periprocedural bleedings; nevertheless, their relative efficacy is largely undetermined. We aimed to perform a systematic review and meta-analysis of available studies comparing the efficacy of RA and FA with hemostasis by VCD (FA + VCD) on the reduction of access-site complications and/or periprocedural bleedings...

BACKGROUND: Current guidelines recommend 12 months of dual-antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation. Whether the duration of DAPT can be safely shortened with use of second-generation DESs is unclear. METHODS: We conducted a meta-analysis of randomized controlled trials comparing short duration (SD) (3-6 months) with standard longer duration (LD) (≥12 months) DAPT in patients treated with primarily second-generation DES implantation...

OBJECTIVES: Right heart catheterization is an important diagnostic tool but carries risks of adverse events. Little is known about the feasibility and safety of using dialysis arteriovenous (AV) shunts. We aim to evaluate the feasibility and safety of using dialysis AV shunts for access in right heart catheterization. METHODS: Hemodialysis patients who required right heart catheterization were prospectively enrolled. A 7 Fr sheath was inserted and a balloon-tipped pulmonary artery catheter was advanced for right heart catheterization...

We present a case where conventional wire and equipment passage through the proximal cap of a chronic total occlusion due to in-stent restenosis was not possible. The lesion was then safely and successfully treated by deliberate passage into the subintimal space outside the previous stent with subsequent subintimal dissection and reentry into the true lumen beyond the occlusion. We then stented around the occluded stent, effectively crushing the previous stent in the true lumen and restoring flow by stenting open the new subintimal lumen...

Coronary artery fistula is a rare anomaly; large fistulae may result in myocardial ischemia from coronary steal. We present the case of a 73-year-old male who presented with exertional angina; imaging demonstrated severe coronary artery disease and a large coronary artery fistula. Ligation of the fistula resulted in severe right ventricular failure and cardiogenic shock. After reestablishing flow to the fistula, the patient recovered. We speculate that the ischemia-induced angiogenesis from the congenitally present fistula made what may have otherwise been an innocent fistula into an important nutritive supply, which remained important despite distal revascularization...

OBJECTIVES: We aimed to illustrate one of the mechanisms of rotational atherectomy burr entrapment in a coronary stent where the burr was rolled up in the stent's struts. METHODS: We report a case where the treatment of a mid right coronary artery (RCA) lesion using a rotational atherectomy device was attempted. During the procedure, the burr suddenly got stuck in a freshly implanted stent in the distal RCA. Despite several attempts and maneuvers, we were unable to pull back the burr...

Although the feasibility and safety of robotically assisted peripheral vascular intervention (PVI) for iliac and femoral peripheral arterial disease (PAD) have been demonstrated, robotic PVI for below-the-knee disease has never been reported. We present the first description of robotic PVI with the CorPath Vascular Robotic System (Corindus) for treating below-the-knee PAD. After contralateral sheath placement in the affected lower extremity, the entire procedure was performed robotically with remote control of the guidewire and angioplasty balloon...

OBJECTIVES: To determine the patient radiation exposure and contrast agent variation during transcatheter aortic valve implantation (TAVI) procedures resulting from technological improvements. METHODS: TAVI procedures from January 2008 to July 2015 were analyzed in three different time periods: 1st period, when the angiography was equipped with an image intensifier technology; 2nd period, starting with the installation of a new angiography system with flat-panel detector (FPD) technology; and 3rd period, starting with the systematic use of preprocedural multidetector computed tomography (MDCT) to individualize optimal fluoroscopic projections for the aortic prosthesis implantation...

OBJECTIVES: We evaluated the relationship between gender and angiographic and clinical outcomes in patients with severely calcified lesions who underwent orbital atherectomy. BACKGROUND: Female gender is associated with increased risk of adverse clinical events after percutaneous coronary intervention (PCI). Severe coronary artery calcification increases the complexity of PCI and increases the risk of adverse cardiac events. Orbital atherectomy is effective in plaque modification, which facilitates stent delivery and expansion...

Ventricular interdependence is a salient hemodynamic feature of cardiac tamponade that manifests as discordance between the left and right ventricles in filling and ejection on hemodynamic assessment. Ventricular interdependence can manifest as arterial discordance at the level of the great arteries.
