Patient Characteristics, Procedural Details, and Outcomes of Contemporary Percutaneous Coronary Intervention in Real-World Practice: Insights from Nationwide Thai PCI Registry.

Background: Percutaneous coronary intervention (PCI) practice and outcomes vary substantially in different parts of the world. The contemporary data of PCI in Asia are limited and only available from developed Asian countries.

Objectives: To explore the pattern of practice and results of PCI procedures in Thailand as well as a temporal change of PCI practice over time compared with the registry from other countries.

Visual-functional mismatch and results of fractional flow reserve guided percutaneous coronary revascularization.

Objective: To identify mismatches in the significance ofcoronary artery stenosis determined by physician 's visual estimation (VE) vs. quantitative coronary angiography (QCA), by VE vs. fractional flow reserve (FFR), and independent predictors for mismatch between VE and FFR.

Cases report: Experience with rheolytic thrombectomy device (Angiojet) in acute ST elevation myocardial infarction with large amount of coronary thrombus.

Background: Primary percutaneous coronary intervention (PCI) in acute ST elevation myocardial infarction (STEMI) is a clinical challenge. Adequate thrombus removal before stenting is an important factor that predicts procedural success, and finally reflects to clinical outcomes.

Cases Report: In the present report, 2 cases of acute STEMI underwent primary PCI.

Percutaneous coronary intervention in patients with anomalous origin of coronary artery.

Percutaneous coronary intervention in patients with anomalous origin of right coronary artery from left sinus of Valsalva was performed in Central Chest Institute during 2005-2009. The diagnosis of this type of congenital anomaly is always difficult, since it requires high operator's consideration and experience. Standard catheter curve desired for general coronary angiography is also not suitable for the abnormal origin of artery, especially when coronary intervention is to be performed.

Factors related to in-hospital heart failure are very different for unstable angina and non-ST elevation myocardial infarction.

Non-ST-elevation myocardial infarction (NSTEMI) and unstable angina (UA) resulted in different degrees of damage to the heart muscle, and yet, when factors related to in-hospital outcomes were examined, these two subsets were often lumped together as non-STelevation acute coronary syndrome. Therefore, we investigated predictors of in-hospital heart failure (HF) in UA and NSTEMI separately. Factors related to HF (Killip > or = 2) were analyzed for NSTEMI and UA in a Thai Acute Coronary Syndrome (ACS) registry conducted in 17 institutions between 2002 and 2005.

Experience of percutaneous mechanical mitral commissurotomy using metallic commissurotome in patients with mitral stenosis at chest disease institute.

Background: Percutaneous metallic mitral commissurotomy (PMMC) has been accepted as an alternative to the traditional balloon technique. The advantage of the metallic commissurotome is that it is designed for several reuse and resterization and it is an interesting tool as seen by the authors.

Objective: To evaluate the efficacy and safety of PMMC among a wide range of patients with severe mitral stenosis.

Effect of un-fractionated heparin and low molecular weight heparin on hospital mortality in patients with non ST elevation acute coronary syndrome (ACS).

Background: The Thai ACS registry is a multi-center prospective registration that describes the epidemiology, management practices and in-hospital outcomes of patients with acute coronary syndromes.

Objective: Study the registry difference in hospital outcomes about cardiac death and length of stay between low molecular weight heparin (LMWH) and un-fractionated heparin (UFH).

Material And Method: This is an observational descriptive study.

Significance of lead aVR ST segment elevation in acute coronary syndrome.

Objectives: To study the relation between lead aVR ST segment elevation (aVRSTE) and angiographic_coronary artery lesions in patients with acute coronary syndrome (ACS).

Material And Method: From January 2001 to December 2001, the authors retrospectively studied 26 consecutive patients who were admitted to the coronary care unit, Chest Disease Institute with ACS. The admission 12-lead EKGs,chest X-ray, troponin T, creatine phosphokinase (CPK), creatine kinase MB fraction (CK MB) and blood chemistry including fasting blood sugar, renal function test (BUN and creatinine), electrolytes and lipid profiles were obtained and analyzed before coronary angiogram.
