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.
Dominance/submission is an element within the practice of sadomasochism. In a Dom/sub (sometimes written as D/s - BIG D, little s) relationship the Dom is the boss (Master) and the sub is submissive. Some relationships are full time almost a Master slave relationship some are for play only.
