2012年12月1日 · Most stent and angioplasty procedures (also known as percutaneous coronary interventions or PCIs) are performed in the same session as the diagnostic catheterization -- this is referred to as "ad hoc PCI".

Ad hoc PCI has increased in prevalence over the past decade and is the default strategy for treating acute coronary syndromes. However, questions about its appropriateness for some patients with stable symptoms have been raised by the results of recent large trials comparing PCI to medical therapy or bypass surgery.

2003年12月1日 · Combination of coronary angiography and PTCA as a single procedure, so-called ‘ad hoc’ PTCA, is becoming common practice in many institutions [8], [9], [10], but the feasibility of this strategy performed with the transradial approach in a large group of patients has not been evaluated.

2012年11月29日 · Percutaneous coronary interventions (PCI) may be performed during the same session as diagnostic catheterization (ad hoc PCI) or at a later session (delayed PCI). Ad hoc PCI for stable ischemic heart disease requires pre-procedural planning, and reassessment after diagnostic angiography must be performed to ensure its appropriateness.

Ad hoc PCI has increased in prevalence over the past decade and is the default strategy for treating acute coronary syndromes. However, questions about its appropriateness for some patients with stable symptoms have been raised by the results of recent large trials comparing PCI to medical therapy or bypass surgery.

In the ad hoc PTCA group, 92% of the culprit lesions were successfully treated; complications included myocardial infarction (2%), urgent bypass surgery (0.6%) and death (0.9%). The rate of combined procedure progressively increased from 54% in 1990 to 88% in 2000, with a significant decrease in the rate of complications.

Ferdinand Kiemeneij's work in transradial angioplasty and stenting has taken invasive cardiology into the exciting new era of "minimally invasive coronary intervention". Methods and results: Fifty consecutive patients underwent Transradial Percutaneous Transluminal Coronary Angioplasty (PTCA) with or without stenting from mid March 98-December 98.

2012年12月1日 · One stop shopping…or stenting: ad hoc angioplasty! What was gained was efficiency, less patient discomfort, lower costs…what was lost was that period of decision-making, of debate about the best way forward.

Ad-hoc coronary intervention is particularly suitable for patients with clinical evidence of restenosis 6 to 12 months following the initial procedure, patients undergoing primary angioplasty for MI, and patients with refractory unstable angina in need of urgent revascularization.
