	Rare Breed Network: Patterdale Terrier
		The PTCA holds one annual event each year at a different location, in conjunction with a national hunt No judging of the dogs is evident in the national hunt, but one may be designated as "outstanding" from his/her performance prior to the show.
		The PTCA had open registration until September, 1996 at which time it was suggested that an owner should send a 2 generation pedigree and a photograph of any terrier submitted for a registration number.
		Litters are not registered with the PTCA, but an important aspect on a member's application to the club is the indication that they work/hunt their Patterdales or support the concept of working/hunting.

	PTCA vs. CABG -- CTSNet FAQs
		Nine randomized trails have addressed the relative benefit of PTCA and CABG in patient population of 5,200 patients, including those with two- or three- vessel disease.
		Need for secondary procedures was most marked in the PTCA group, which required one or more secondary procedures in 70% of the PTCA population at five years in comparison to 10% of the CABG population.
		PTCA was less expensive than CABG in non-diabetic, two-vessel disease and in younger patients.

	Guideline 32 Section 3: Percutaneous transluminal coronary angiplasty (Site not responding. Last check: 2007-10-09)
		Percutaneous transluminal coronary angioplasty (PTCA) seeks to restore blood flow to ischaemic myocardium by transiently inflating a balloon in a coronary stenosis and thereby increasing the luminal area of the artery.
		PTCA has a high success and low complication rate for ideal lesions but a low success and high complication rate for complex lesions (see Annexes 3 and 4).
		This strategy, known as `culprit lesion PTCA', is often appropriate in symptomatic patients with multivessel coronary artery disease who have a single exceptionally severe stenosis and many minor lesions, or in those patients who are unsuitable for CABG because of co-morbid conditions such as cerebrovascular disease or chronic obstructive airways disease.

	Method and apparatus for determining the success of a PTCA procedure - Patent 5142558
		Still another object of the invention is to provide a device which allows a radiologist to compare arterial blood flow before and after the PTCA procedure so as to avoid, on the one hand, unnecessary inflation(s) of the balloon catheter, and on the other hand, premature withdrawal of the balloon catheter from the patient's body.
		Therefore, the radiologist is presented with two comparable opacified images of the same stenotic area, one representing the status of the stenosis and the dynamic action of the heart before the PTCA procedure and the other representing the status of the stenosis and the dynamic action of the heart afterward.
		When, after the performance of the PTCA procedure and before the balloon catheter has been withdrawn from the patient's body, the radiologist wishes to compare blood flow through the previously blocked arterial region after the procedure with the flow before the procedure.

	Pros and Cons of PTCA and CABG
		Comparisons of previous non-randomised studies of CABG and PTCA were restricted by differences in the extent of coronary artery disease and the severity of left ventricular dysfunction present.
		Furthermore the patients receiving PTCA were often treated only for the vessel thought to be responsible for the symptoms, a strategy known as 'culprit lesion PTCA'.
		PTCA was used initially in patients with single-vessel disease.

	Coronary angioplasty - PTCA procedure opens blocked arteries
		Percutaneous transluminal coronary angioplasty (PTCA) — often abbreviated to angioplasty — is a procedure to re-open a narrowed heart artery by inflating a tiny balloon in the narrowed segments.
		PTCA is a procedure performed in hospital cardiology units, in a specially-equipped room often called a catheterisation lab (or "cath lab" for short).
		To place the balloon correctly, the doctor inserts a fine tube (catheter) into a large artery in the groin or arm and then a guidewire, with the deflated balloon at the end, is passed down the tube.

	coronary artery disease - Hutchinson encyclopedia article about coronary artery disease
		Most effective is bypass surgery – an operation called coronary artery bypass grafting (CABG) – to replace narrowed sections of artery.
		The endoscopic procedure, known as percutaneous transluminal coronary angioplasty (PTCA), involves the use of a balloon-tipped catheter to widen the diseased vessel.
		PTCA is cheaper and less invasive than CABG, but in roughly a third of cases further surgery is required in six months.

	Better Control Of Chest Pain With PTCA Rather Than Drugs (Site not responding. Last check: 2007-10-09)
		Death or heart attack occurred in 32 (6.3 percent) of patients treated with PTCA and in 17 (3.3 percent) of patients treated with conservative care; a significant difference.
		The authors conclude that, "The benefits of PTCA over medical treatment were largely concentrated in patients with both severe angina and poor exercise time." However, they also warn that "When managing individuals with angina, clinicians must balance these benefits against the small excess hazard associated with PTCA due to procedure-related complications".
		PTCA is known to be an effective procedure for the relief of chest pain but its use is controversial for patients whose symptoms are adequately controlled by medical treatment.

	ptca
		Previously the criteria for a PTCA was single vessel occlusion that is exclusive of the left main coronary artery, a plaque lesion that is concentric, noncalcified, proximal, less than 1 cm, and does not totally occlude the vessel.
		A PTCA patient can also be normally asymptomatic but show signs of ischemic areas on a stress test.
		PTCA is performed in the cardiac catheterization laboratory, by means of flouroscopy.

	SHOULD LOW-RISK CARDIAC PATIENTS HAVE PTCA? - Journal Watch (General)
		After a median follow-up of 2.7 years, the risk for death or MI was significantly greater in the PTCA group than in the medical-management group (6.3 vs. 3.3 percent), largely due to an excess of procedure-related events.
		However, relief of symptoms (e.g., angina, breathlessness, and exercise tolerance) was significantly better with PTCA; this benefit was concentrated mainly in those with more severe symptoms at baseline (angina grade 2 or higher and an exercise time less than 9 minutes).
		PTCA provides significantly better symptomatic improvement in patients with more severe symptoms, but this benefit should be balanced against the risk for procedure-related adverse events.

	Drug delivery PTCA catheter and method for drug delivery - Patent 5397307
		The catheter is ideally suited for use after a PTCA procedure, wherein the proximate balloon seals the blood vessel while the distal balloon is uniquely contoured when inflated to define fluid communication paths therepast and proximate a blood vessel to be treated.
		A percutaneous transluminal coronary angioplasty (PTCA) procedure typically consists of introducing a catheter with a single inflatable balloon into a patient's vascular system and positioning the balloon proximate a stenotic lesion to be treated.
		With the balloon juxtaposed relative to the blockage or constriction, an inflation fluid is introduced through a lumen of the catheter and made to inflate the balloon to expand the balloon against the blockage and to spread or open the obstructed blood vessel.

	Review 2 (Site not responding. Last check: 2007-10-09)
		Both PTCA and CABG have changed dramatically since that time, especially with the introduction of coronary stents and minimally invasive CABG." Although trials to compare CABG with PTCA carried out with contemporary methods are under way (Arterial Revascularization Therapy Study and the Stent or Surgery study); the EAST study nonetheless has much to teach.
		However, PTCA patients inevitably require more repeat interventions to maintain their long-term functional capacity and angina-free status, and the incidence of crossovers to surgery increases as time goes by.
		Since initial and long-term costs of PTCA in registry patients were lower than in randomized patients (Figure), the study's authors conclude, and I agree, that in nonrandomized patients therapeutic decisions for PTCA or for CABG were appropriately made by physicians and patients, and outcomes were satisfactory.

	Sun.Star General Santos - Solution seen in GSNSAT, PTCA row
		FINALLY, members of the Parents-Teachers and Community Association (PTCA) of the General Santos National School of Arts and Trade (GSNSAT), together with the Technical Education Skills and Development Authority (Tesda) and the Department of Education (DepEd), decided to sit down and settle their problem once and for all.
		PTCA members, however, raised a howl of protest against the Tesda management of the school because it has required each high school student to pay P520 annually for the Tesda teachers.
		The PTCA are likewise staking claims on school improvements they have initiated like the construction of buildings and other facilities.

	Coronary Angioplasty - Heart Disease and other cardiovascular conditions on MedicineNet.com
		PTCA is a non-surgical procedure that relieves narrowing and obstruction of the arteries to the muscle of the heart (coronary arteries).
		PTCA is accomplished with a small balloon catheter inserted into an artery in the groin or arm, and advanced to the narrowing in the coronary artery.
		When successful, PTCA can relieve chest pain of angina, improve the prognosis of patients with unstable angina, and minimize or stop a heart attack without having the patient undergo open heart coronary artery bypass graft (CABG) surgery.

	ESC: Good outcomes are achieved with PTCA of saphenous grafts (Site not responding. Last check: 2007-10-09)
		Gruetters and colleagues from the Medical Clinic, Cardiology Clinic, Kiel, Germany assessed the long-term outcome of 424 percutaneous transluminal coronary angioplasty (PTCA) procedures in bypass grafts of 294 patients done at their clinic between 1988 and 2000.
		The initial success rate of PTCA was 94 percent, with success being defined as less than 50 percent residual stenosis of the vessel.
		According to the authors, PTCA of saphenous grafts can be performed with a high degree of initial success and a moderate degree of later restenosis.

	Sustained improvement in myocardial perfusion four to six years after PTCA in patients with a satisfactory angiographic ...
		During follow-up, two patients had recurrent angina due to progression of coronary artery disease requiring a second PTCA procedure of another coronary artery; one of them later had a limited myocardial infarction in an area supplied by the vessel initially dilated.
		Myocardial perfusion during exercise in the PTCA-related area, assessed by SPECT, was normal in 90% of the patients and showed a limited defect due to reversible ischaemia in the remaining four (10%).
		It is concluded that patients with a less than 50% stenosis six months after PTCA show sustained improvement in their functional status and myocardial perfusion, four to six years after the procedure suggesting continued patency of the coronary artery.

	Percutaneous Transluminal Coronary Angioplasty
		A PTCA is a procedure that opens narrowed arteries to increase blood flow.
		A PTCA may be done instead of coronary artery bypass surgery depending upon the type and location of the narrowing, the extent of the disease and the risk involved.
		The patient is given a mild sedative to help him relax but remains awake during the procedure to allow him to answer questions regarding his comfort level, any chest pain or shortness of breath.

		In those patients who did sustain a Q-wave myocardial infarction in the follow-up period, patients with diabetes who were randomized to PTCA had an alarming rate of early mortality after their myocardial infarction.
		In the relatively small subset of patients with treated diabetes, 8-year survival favored surgery (75.5%) versus PTCA (60.1%), although the differences were not statistically significant (p=0.23).
		In this study in consecutive patients with diabetes, angiography was performed at 6 months after PTCA to evaluate the presence of restenosis.
