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...

AIMS: Impella is a microaxial rotary pump that is placed across the aortic valve to expel aspirated blood from the left ventricle into the ascending aorta; it can be used in cardiogenic shock. While previous studies have evaluated the efficacy and safety of the Impella device, more clinically relevant data are necessary, especially with regard to outcomes. METHODS AND RESULTS: We screened our database of Impella patients in our heart center and found 68 consecutive patients who underwent Impella implantation due to acute coronary syndrome (ACS) complicated by cardiogenic shock...

AIMS: To evaluate the safety and efficacy of a novel technique with simultaneous compression of the ulnar artery in order to reduce the incidence of radial artery occlusion (RAO) after transradial cardiac catheterizations. METHODS AND RESULTS: Ipsilateral ulnar artery transient compression for 1 hour facilitating radial artery patent hemostasis (ULTRA) was performed in all patients treated transradially in October 2015 and was compared with patients treated with conventional patent hemostasis in September 2015...

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.

A patient presented with an inferior non-ST segment elevation myocardial infarction and a tight lesion on the distal right coronary artery. After stent implantation, a large scaffold malapposition was observed by optical coherence tomography. This case emphasizes the importance of not expanding a bioresorbable vascular scaffold more than 0.5 mm over its nominal size.

A 47-year-old male smoker with recent cocaine use presented with 6 hours of chest pain unrelieved by sublingual and intravenous nitroglycerin. To our knowledge, this is the first reported case demonstrating the efficacy of an intracoronary calcium-channel blocker to ameliorate cocaine-induced microvascular spasm.

OBJECTIVES: Aortic valve preparation with balloon aortic valvuloplasty (BAV) has been previously considered mandatory during transcatheter aortic valve implantation (TAVI) procedures. BAV-inherent risks including stroke, conduction abnormalities, and reduced device profile size established the rationale for safe valve deployment without the need for aggressive valve preparation. We investigate the feasibility and safety of performing Sapien 3 (S3; Edwards Lifesciences) balloon-expandable TAVI with moderate or without predilation (PD)...

OBJECTIVE: Surgical femoral cutdown for decannulation after veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is considered standard practice. However, access-site complications with this technique are not rare. The objective of this study is to evaluate feasibility, safety, and efficacy of a complete percutaneous decannulation procedure after VA-ECMO compared with the conventional surgical cutdown approach. METHODS: In 35 patients who were successfully weaned from VA-ECMO support, femoral artery and vein access sites were closed using a completely percutaneous approach in 15 patients, whereas 20 patients had conventional surgical cutdown for access-site closure...

OBJECTIVES: Human immunodeficiency virus (HIV) seropositive individuals are predisposed to acute myocardial infarction (AMI). We sought to evaluate management strategies and outcomes of AMI in patients with HIV in the contemporary era. METHODS: We analyzed data from the National Inpatient Sample from 2002 to 2011 for patients admitted with AMI with or without HIV. Propensity-score matching was used to identify HIV seropositive AMI patients with similar characteristics who were managed invasively (cardiac catheterization, percutaneous coronary intervention [PCI], or coronary artery bypass graft surgery [CABG]) or conservatively...

OBJECTIVES: We sought to determine the impact of proximal cap ambiguity on procedural techniques and outcomes for coronary chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS: We examined the clinical and angiographic characteristics and outcomes of 1021 CTO-PCIs performed between 2012 and 2015 at 11 United States centers. RESULTS: Proximal cap ambiguity was present in 31% of target lesions and was associated with increased clinical and angiographic complexity (prior coronary artery bypass graft surgery: 43% vs 33%; P=...

OBJECTIVES: To compare procedural success and safety of pericardiocentesis using continuous ultrasonographic visualization of a long (7 cm) micropuncture needle to standard access with an 18 gauge needle without continuous ultrasound guidance. BACKGROUND: Current approaches to pericardiocentesis commonly utilize a large-bore 18 gauge needle for access without allowing for continuous visualization of needle entry into the pericardial space. METHODS: We included all consecutive patients at our institution who underwent pericardiocentesis between November 1, 2011 and March 3, 2016...

Percutaneous repair of the mitral valve has been widely adopted for the treatment of primary, symptomatic severe mitral regurgitation in patients at prohibitive risk for surgical intervention. We present a case of an elderly female patient with moderate-to-severe mitral regurgitation who underwent MitraClip procedure, with postprocedural course remarkable for the development of right-to-left shunting and hypoxia, for which the patient underwent a percutaneous repair of the atrial septal defect with immediate recovery of oxygen saturation...
