A novel technique to avoid perforation of the right ventricle by the temporary pacing lead during transcatheter aortic valve implantation.

Cardiovasc Interv Ther 2020 May 30. Epub 2020 May 30.

Department of Cardiology, Keio University School of Medicine, 35 Shinanomachi, Shinjuku-ku, Tokyo, 160-8582, Japan.

Cardiac tamponade is a life-threatening complication during transcatheter aortic valve implantation (TAVI), often caused by perforation of the right ventricle (RV) by the temporary pacemaker used for rapid pacing during valve deployment. We aimed to assess the feasibility of performing rapid pacing while maintaining inflation of the pacing lead balloon in the RV during TAVI. Among 749 consecutive patients who underwent TAVI with SAPIEN XT valves between October 2013 and July 2015, 726 treated using rapid pacing with a transvenous balloon-tip lead were enrolled in our study, and were stratified into three groups according to the extent of balloon inflation in the RV as follows: full inflation (n = 100), partial inflation (n = 196), and deflation (n = 430).

Cardiovasc Interv Ther 2020 May 27. Epub 2020 May 27.

Pediatric Cardiac Center, College of Medicine, Queen Sirikit National Institute of Child Health, Rangsit University, Bangkok, Thailand.

Transcatheter closure of ventricular septal defect (VSD) is an alternative treatment of surgery. However, because of the potential risk of the complete atrioventricular block (AVB) and the lack of available dedicated devices for VSD, this procedure rarely used most centers. Recently in Thailand, with distinct device design that may cause less clamp force and radial force, the AmplatzerDuct Occluder (ADO) II has become available for the closure of small VSDs. Read More

Contrast-induced acute kidney injury.

Cardiovasc Interv Ther 2020 Jul 6;35(3):209-217. Epub 2020 Apr 6.

Center for Interventional Cardiovascular Research and Clinical Trials, The Zena and Michael A. Wiener Cardiovascular Institute, Icahn School of Medicine at Mount Sinai, One Gustave L. Levy Place, Box 1030, New York, NY, 10029-6574, USA.

Although major advancements in the field of cardiology have allowed for an increasing number of patients to undergo minimally invasive imaging and interventional procedures, contrast-induced acute kidney injury (CI-AKI) continues to be a dreaded complication among patients receiving intravascular contrast media. CI-AKI is characterized by progressive decline in kidney function within a few days of contrast medium administration. Physiological changes resulting from the direct nephrotoxic effect of contrast media on tubular epithelial cells and release of vasoactive molecules have been implicated in creating a state of increased oxidative stress and subsequent ischemic renal cell injury.

In vivo validation of resting full-cycle ratio and diastolic pressure ratio: simultaneous measurement with instantaneous wave-free ratio.

Cardiovasc Interv Ther 2020 Feb 11. Epub 2020 Feb 11.

Cardiovascular Division, Department of Cardiovascular Medicine, Gifu Heart Center, Yabutaminami, Gifu City, Gifu, 500-8384, Japan.

The diastolic pressure ratio (dPR) and resting full-cycle ratio (RFR) are considered to be almost identical to the instantaneous wave-free ratio (iFR) in the retrospective analysis of pooled data. The aim of this study was to investigate the direct comparison of iFR and these new resting indexes in real world practice. Two pressure wires were inserted and placed in the distal part of the same coronary artery. Read More

Operators' radiation exposure reduction during cardiac catheterization using a removable shield.

Cardiovasc Interv Ther 2020 Feb 7. Epub 2020 Feb 7.

Interventional Cardiology Unit, "Santa Maria" University Hospital, Via Tristano di Joannuccio 1, 05100, Terni, Italy.

Cardiac catheterization through radial access is associated with significant ionizing radiation exposure for the operator. We aimed at evaluating whether a removable shield placed upon the patient could impact favorably on annual radiation exposure for the operator. We designed a pre-post study comparing radiation exposure in a total of five operators under standard protection procedures (first period) and after applying a removable shield (second period).

Dual antiplatelet therapy in coronary artery disease: from the past to the future prospective.

Cardiovasc Interv Ther 2020 Apr 22;35(2):117-129. Epub 2020 Jan 22.

GVM Care and Research, Maria Cecilia Hospital, Cotignola, Ravenna, Italy.

Antiplatelet therapy, the cornerstone of post coronary stenting antithrombotic therapy, reduces the rate of hard clinical endpoints in patients treated both conservatively and invasively following an acute coronary syndrome, as well as in those patients with chronic stable coronary disease who receive a coronary stent. The development of newer antiplatelet and direct anticoagulant agents provides new options in the antithrombotic management of patients with coronary artery disease, enabling different therapeutic combinations to be tailored to an individual patient's bleeding and ischemic risk profile. In this review, we will summarize the history of dual antiplatelet therapy, discuss the latest evidence and future perspectives in treating patients with coronary artery disease. Read More

Confirmation of maximal hyperemia by the incremental dose of intracoronary papaverine.

Cardiovasc Interv Ther 2020 Jan 14. Epub 2020 Jan 14.

Cooperative Major in Advanced Biomedical Sciences, Joint Graduate School of Tokyo Women's Medical University and Waseda University, 2-2 Wakamatsucho, Shinjuku, Tokyo, 162-8480, Japan.

We investigated the effect of the papaverine dose increment method to confirm maximal hyperemia for fractional flow reserve (FFR) measurements. We evaluated 115 consecutive patients involving 200 lesions. FFR was measured after intracoronary papaverine injection into the left (12 mg) and right (8 mg) coronary arteries as standard doses.

Is crossability of the classic crown with the glide assist superior to the micro crown in the Diamondback 360® coronary orbital atherectomy system?

Cardiovasc Interv Ther 2020 Jan 14. Epub 2020 Jan 14.

Department of Medical Science and Cardiorenal Medicine, Yokohama City University Graduate School of Medicine, 3-9 Fukuura, Kanazawa-ku, Yokohama, 236-0004, Japan.

The Diamondback 360® coronary orbital atherectomy system (OAS) can safely debulk calcified lesions by pullback of the crown, if the crown is advanced to the distal of the lesion. The aim of this study was to compare crossability with two types of crown in OAS. Thirty-six consecutive severely calcified lesions in 33 patients who underwent percutaneous coronary intervention with the coronary OAS were included. Read More

Efficacy of optical frequency-domain imaging in detecting peripheral artery disease: a single-center open-label, single-arm study protocol.

Cardiovasc Interv Ther 2020 Jan 2. Epub 2020 Jan 2.

Division of Cardiovascular Medicine, Department of Internal Medicine, Kobe University Graduate School of Medicine, Kobe, Japan.

Intravascular optical coherence tomography is a high-resolution intracoronary imaging modality, providing a microscopic image of intravascular features. However, it has lower penetration depth than intravascular ultrasound. Recently, a second-generation optical frequency-domain imaging (OFDI) technique has been developed to provide greater penetration depth and faster pullback speed. Read More

Chronic thromboembolic pulmonary hypertension (CTEPH) is classified as Group-4 pulmonary hypertension caused by organized thrombi in pulmonary arteries. Pulmonary endarterectomy (PEA) has been shown to improve the symptoms and prognoses of patients with proximal CTEPH. The soluble guanylate cyclase stimulator (riociguat) is the sole FDA-licensed drug for the treatment of CTEPH, and guidelines recommend its use for patients with inoperable CTEPH or residual or recurrent pulmonary hypertension following PEA.
