Arterial access from lower extremity. The common femoral artery is the only access site used in the lower extremity. Catheters used for performing coronary angiography via the femoral artery were developed by Melvin Judkins, MD; thus, the method often is referred to as the Judkins technique. This widely used method requires separate preformed catheters for the right and left coronary arteries (see the images below).
Urethral sounds/play, sometimes called sounding, is basically inserting objects (often steel sounds and catheters) into the urethra for erotic purposes. Sounds painful and unpleasant to most, but some people get a kick out of this.
A mid-to-late diastolic rumble heard at the apex (Austin Flint murmur) may result from rapid regurgitant flow into the LV, causing mitral valve leaflet vibration at the peak of atrial flow; this murmur mimics the diastolic murmur of mitral stenosis.
