Percutaneous coronary intervention (PCI), the procedure used to place stents, is a medical procedure that is commonly known as coronary angioplasty. Another problem that can occur after PCI is too much tissue growth within the treated portion of the artery. This can cause the artery to become narrow or blocked again.
Sadomasochism can be defined as the giving or receiving of pleasure, often sexual, from the infliction or reception of pain or humiliation. It can feature as an enhancement to sexual pleasure, or, in some cases, as a substitute or sine qua non.
The term BDSM is first dated from 1969. The term BDSM was formed by joining the term B&D (bondage and discipline) with S&M (sadomasochism, or sadism and masochism). It is sometimes believed to contain within it the compound D&S (dominance and submission) but this is an example of folk etymology. BDSM is used today (2015) as a catch-all phrase covering a wide range of activities, forms of interpersonal relationships, and distinct subcultures.
