Abstract
Guiding catheters have larger lumen diameter as compared to the same size diagnostic catheters, and thus provide adequate arterial blood flow and good visualization of the artery during percutaneous coronary intervention. However, feasibility of percutaneous coronary intervention via diagnostic catheters has been demonstrated in a few studies. This case reports the use of a 6 French diagnostic catheter for both the coronary angiography as well as coronary stenting in a 52-year-old male patient with critical mid left anterior descending artery stenosis on December, 2012.

Highlights
To achieve a successful coronary artery stenting guiding catheter with good back-up support is vital
If the cannulation of desired coronary artery with guiding catheter following diagnostic angiography is difficult and time taking despite the use of the catheter having similar shape, the use of a diagnostic catheter for coronary stenting may be attractive
Left coronary artery was hooked with 6 French (F) 3.5 cm curve Judkins left diagnostic catheter (Cordis) which showed critical stenosis at the middle segment of the left anterior descending artery (LAD) (Figure 1)
Summary
To achieve a successful coronary artery stenting guiding catheter with good back-up support is vital. Sometimes standard guiding catheters may not selectively cannulate the desired coronary ostium despite a successful cannulation with a diagnostic catheter of the same curve. Left coronary artery was hooked with 6 French (F) 3.5 cm curve Judkins left diagnostic catheter (Cordis) which showed critical stenosis at the middle segment of the LAD (Figure 1). Since the patient had severe ongoing chest pain, and the canulation of the left coronary artery with the guiding catheter was difficult and taking more time, we used the same 6 F Judkins left 3.5 cm curve diagnostic catheter which was used for the diagnostic coronary angiography. Lesion was predilated with a Sprinter compliant balloon (Medtronic) measuring 2 × 10 mm at 12 Atm (Figure 2), followed by the deployment of a cobalt chromium
