Intracoronary Bubbles

Intracoronary ultrasound.

Although contrast angiography is important in the diagnosis and treatment of atherosclerotic disease, it does have limitations. Intracoronary ultrasound more accurately assesses the amount of atherosclerosis and has given us new insights into the pathophysiology of coronary plaque accumulation and remodelling. It also allows the monitoring of therapeutic intervention. Intracoronary ultrasound i...

Intracoronary electrocardiogram.

SEE PAGE 988 A nimal studies on the intracoronary electrocardiogram (IC ECG) preceded coronary angioplasty, today referred to as percutaneous coronary intervention (PCI), by 1 year, almost 40 years ago (1). Even the balloon was there, but it was used for temporary coronary occlusion producing ischemia rather than for treating coronary stenoses. In 1983, pacemaker electrodes were used to derive ...

Intracoronary and Epicardial Bradykinin

Background. Stimulation of left ventricular (LV) receptors with sympathetic afferents generally results in reflex sympathoexcitatory responses. Stimulation of LV receptors with vagal afferents results in reflex sympathoinhibitory responses. Vagal afferents are known to be preferentially distributed to the inferoposterior (IP) wall of the LV. We tested the hypothesis that there is also a prefere...

Failure of Intracoronary Nitroglycerin

Relief of angina by nitroglycerine has been attributed to two possible mechanisms: (1) Increase in myocardial blood supply by direct acton of the drug on the coronary arteries. (2) Reduction in myocardial oxygen demand by action of the drug on the systemic circulation. Sublingual application of nitroglycerin in previous studies did not allow the ruling out of the operation of either or both mec...
