Contemporary retrograde approach for the recanalisation of coronary chronic total occlusion: on behalf of the Japanese Retrograde Summit Group.

AIMS The retrograde approach to CTO is promising, but questions remain with regard to its wider application and the potential risks. This study evaluated the feasibility and efficacy of retrograde recanalisation of chronic total occlusion (CTO) of the coronary arteries. METHODS AND RESULTS A total of 378 consecutive patients (previously failed PCI 32.0%) who enrolled in 27 institutions in Japan underwent retrograde recanalisation for CTO. We analysed the data on lesion characteristics, procedural materials, technique used, complications and clinical outcomes. Successful retrograde recanalisation was achieved in 70.4% and the overall procedural success was 83.6%. Collateral crossing was achieved via a septal route in 68.9%, epicardial in 27.2% and bypass grafts in 2.6%, respectively. The retrograde approach was completed with implementation of reverse CART in 42.5%, direct wire crossing in 23.1%, bilateral wiring in 22.7%, and CART in 11.7%. Major and minor collateral injuries and coronary perforations were noted in 1.3%, 10.3% and 2.9% of cases, respectively. Stroke occurred in 0.3%, QWMI and emergency PCI in 0.3% of patients with successful recanalisation. CONCLUSIONS Wider application of retrograde CTO PCI achieved a high rate of success in recanalisation with an acceptable rate of complications in Japan.

Complications during retrograde approach for chronic coronary total occlusion: Sub-analysis of Japanese multicenter registry.

This study was performed to determine the complications occurring during retrograde percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) based on analysis of the multicenter, prospective, nonrandomized Retrograde Summit registry.

Independent predictors of retrograde failure in CTO-PCI after successful collateral channel crossing.

To evaluate factors for predicting retrograde CTO‐PCI failure after successful collateral channel crossing. Background: Successful guidewire/catheter collateral channel crossing is important for the retrograde approach in percutaneous coronary intervention (PCI) for chronic total occlusion (CTO).

INDEPENDENT PREDICTIVE FACTOR FOR RETROGRADE PROCEDURE FAILURE IN PERCUTANEOUS CORONARY INTERVENTION OF CHRONIC TOTAL OCCLUSION AFTER SUCCESSFUL COLLATERAL CHANNEL CROSSING: SUBANAYSIS OF 1646 CASES FROM JAPANESE MULTICENTER REGISTRY

Methods: Total 1,646 retrograde cases in CTO-PCI were collected from 2009 to 2012 in 44 centers in Japan. Retrograde procedure success was 70.0% and successful collateral channel crossing with wire and any support catheter was achieved in 80.8% (1330) and 76.5% (1260) respectively. Univariate and multivariate analyses were conducted to investigate independent predictors for retrograde procedural failure even after successful collateral channel crossing of any support catheter.

MULTICENTER REGISTRY DATA IN JAPAN FOR RETROGRADE PCI OF CHRONIC TOTAL OCCLUSION DURING THE PAST THREE YEARS: HAVE NEW DEVICES AND TECHNIQUES CHANGED THE STRATEGIES OF RETROGRADE APPROACH?

The aim of Retrograde Summit is to clarify the clinical results which specialize in percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) by retrograde approach. 1166 cases have been registered by 28 hospitals in Japan from 2009 to 2011. We compared successful CTO cases

COMPARISON OF PROCEDURE OUTCOME BY THE VOLUME OF PERCUTANEOUS CORONARY INTERVENTION FOR CHRONIC TOTAL OCCLUSIONS: JAPANESE MULTICENTER REGISTRY WITH TWO YEARS DATA

The serial procedure data of percutaneous coronary intervention (PCI) for chronic total occlusions (CTO) have been collected since 2012 by Retrograde Summit using a web registry system. Total of 3229 eligible subjects who received CTO-PCI were enrolled between January 2012 and December 2013 from 56

PREDICTORS FOR RETROGRADE PROCEDURE FAILURE IN PERCUTANEOUS CORONARY INTERVENTION FOR CHRONIC TOTAL OCCLUSIONS: REPORT FROM JAPANESE MULTICENTER REGISTRY WITH 5 YEARS DATA

Since 2009, the Retrograde Summit has organized a multicenter registry by to examine the efficacy and safety of retrograde PCI for chronic total occlusion (CTO) by Japanese physicians. Total of 2194 retrograde CTO-PCI cases were enrolled between Jan. 2009 and Dec. 2013 from 57 centers in Japan.

A REPORT FROM JAPANESE MULTICENTER REGISTRY DATA FOR CLINICAL RESULTS OF RETROGRADE APPROACH IN PERCUTANEOUS CORONARY INTERVENTIONS FOR CHRONIC TOTAL OCCLUSIONS

In recent years, we attained higher procedural success in percutaneous coronary interventions (PCI) for chronic total occlusions (CTO) due to the development of new devices and techniques. We have established the Retrograde Summit with Japanese investigators for the purpose of promoting these
