These microcatheters can also be maneuvered through a tortuous arterial segment proximal to a lesion by providing extra support to a guidewire. They improve the guidewire penetration ability and could prevent wire tip prolapse/plop ( Figure 1). They are simple to handle and allow wire reshaping or wire exchange without losing the vessel entry. Single-lumen microcatheters (SLMs) are standard microcatheters intended to provide support to enable the placement of guidewires in a vessel. Types of Microcatheter Available for Indian Patients Requiring PCI Procedures Single-Lumen Microcatheters Criteria for the selection of microcatheters-which included a discussion on the selection and preference of one microcatheter over another based on lesion/anatomy-specific criteria or hardware characteristics.Understanding the significance of a microcatheter in the cardiac catheterization lab-which included a discussion on the types of microcatheter available in the Indian market and their significance in PCI procedures.The discussion included broadly the following two topics: The objective of this article is to formulate and deliberate on the recommendations for the selection of microcatheters and their utility in coronary interventional procedures. The use of microcatheters as a coronary interventional tool assists in performing invasive endovascular procedures by serving a broad range of functions in these complex vessel anatomies. thrombus, bifurcation, ostial lesion, calcification, and chronic total occlusions (CTOs) ( 1). This article discusses and summarizes the thoughts and key opinions of experts in this field.Ĭoronary lesions often exhibit certain features posed as challenging while performing a percutaneous coronary intervention (PCI) viz. However, the use of microcatheters and their technicalities have not yet fully realized by many operators and their true scope has not been fully explored. The selection of appropriate crossing techniques with different microcatheters increases success rates of PCI, reduces procedural time and contrast use, and lowers the radiation. The selection of microcatheters involves a detailed understanding of the microcatheter specification, lesion anatomy, lesion location, vessel tortuosity and trajectory, and crossing techniques. During the treatment of such complex lesions, microcatheters play an essential part of the tool kit with both single-lumen and double-lumen microcatheters (DLMs) having their specific niche areas. The use of microcatheters as a coronary interventional tool for a therapeutic approach to complex coronary interventions like bifurcation lesions, ostial location, tortuous anatomy, angled takeoffs, coronary calcification, and chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is growing among cardiologists across the country.
