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.

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.

Benefit of serum-effusion albumin gradient in congestive heart failure patients.

Objective: To compare between light's criteria and serum-effusion (S-E) albumin gradient in diagnosis of transudate effusion in congestive heart failure (CHF) patients.

Material And Method: Eighty-six patients who had pleural effusion and suspected CHF were enrolled in the present study between October 2008- September 2010. Suspected CHF was defined by clinical or echocardiography.

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.

Immediate, short and intermediate results of transcatheter closure of secondum-type atrial septal defect using Amplatzer septal occluder devices.

Objectives: To study the immediate, short, and intermediate results of transcatheter closure of secondum-type atrial septal defect using Amplatzer septal occluder devices (TCAA) in terms of clinical symptoms and residual lesions and shunts determined by transthoracic two-dimensional (TTE) and three-dimensional echocardiography (TDE).

Material And Method: Thirty-six patients, who underwent successful TCAA at the Chest Disease Institute between August 2002 and August 2007 and were followed up clinically, by TTE and TDE at day 1-3, 4-6 months, and 1-year post TCAA, were analyzed.

Results: TCAA was performed in 75 patients during the study period.

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.

Transjugular approach as a challenging access in PTMC: case report.

Advantage of transjugular approach in percutaneous mitral commissurotomy (PTMC) of severe mitral stenotic patients with venous drainage anomalies was obtained as the authors' first case experience. This approach should be considered whenever difficulties are encountered in the femoral approach in PTMC case before valve surgery.
