Long-Term Outcomes of Pharmacoinvasive Strategy Versus Primary Percutaneous Coronary Intervention in ST-Elevation Myocardial Infarction: A Study from Mexico City.

Although primary percutaneous coronary intervention (pPCI) is the treatment of choice in ST-elevation myocardial infarction (STEMI), challenges may arise in accessing this intervention for certain geodemographic groups. Pharmacoinvasive strategy (PIs) has demonstrated comparable outcomes when delays in pPCI are anticipated, but real-world data on long-term outcomes are limited. The aim of the present study was to compare long-term outcomes among real-world patients with STEMI who underwent either PIs or pPCI.

Pulmonary arterial hypertension in children with congenital heart disease: a deeper look into the role of endothelial progenitor cells and circulating endothelial cells to assess disease severity.

Endothelial progenitor cells and circulating endothelial cells have been proposed as useful markers of severity and disease progression in certain vascular diseases, including pulmonary arterial hypertension. Our study focused on evaluating the levels of circulating endothelial progenitor cells and circulating endothelial cells in patients with congenital left-to-right shunts and pulmonary hypertension undergoing definitive repair. Endothelial progenitor cells (identified by simultaneous co-expression of CD45dim, CD34 + and KDR2 + surface antibodies) and circulating endothelial cells (identified by simultaneous co-expression of inherent antibodies CD45-, CD31+, CD146 + and CD105+) were prospectively measured in seventy-four children (including children with Down syndrome), median age six years (2.

Transcatheter closure of paravalvular leaks: short- and medium-term outcomes.

Background: Paravalvular leak (PVL) is a frequent and important complication after surgical valvular replacement that can cause heart failure and hemolytic anemia and is associated with poor clinical outcomes. Surgical reoperation has been the standard treatment, but it is associated with high morbidity and mortality. Transcatheter closure is a therapeutic alternative.

Aortic iatrogenic perforation during transseptal puncture and successful occlusion with Amplatzer ductal occluder in a case of mitral paravalvular leak closure.

Complications of transseptal puncture are significant and potentially life threatening. Aortic perforation is one of these complications and it needs to be repaired immediately. We report the case of a 48-year-old female with a history of rheumatic mitral valve disease.

[Amplatzer® Vascular Plug III, for closing residual mitral paravalvular leak: three-dimensional transesophageal echocardiography image].

Paravalvular leak is a significant complication after surgical valve replacement. Traditionally, redo surgery has been considered the treatment of choice, but is associated with high morbidity and mortality as well as increase risk of developing new leaks. Percutaneous treatment of paravalvular leak appears as an attractive alternative.

[Percutaneous closure of atrial septal defects with the Amplatzer® device: 15 years of experience].

Introduction: Percutaneous closure of atrial septal defects is an alternative to surgical treatment.

Objectives: We report the results of percutaneous closure of atrial septal defects with the Amplatzer(®) device.

Method: We include patients taken to the catheterization laboratory from September 1997 to December 2011.

Intracardiac ultrasound-guided percutaneous mitral valvuloplasty.

Intracardiac echocardiography (ICE) is a relatively new method of ultrasound images useful during cardiac percutaneous interventional procedures. The first human experience with this method was published in 2000 and, since then, several original trials have enrolled this useful method, proving similar and more useful than transesophageal echocardiography in percutaneous treatment of several congenital cardiopathies, like interatrial communication, permeable oval foramen, mitral stenosis, and atrial fibrillation ablation. In this presentation, we publish a single case report of percutaneous mitral valvuloplasty under ICE guidance.

[Transcatheter versus surgical closure of atrial septal defect and patent ductus arteriosus in adults].

We present the results of two studies that compared surgical treatment and percutaneous intervention in two groups of adult patients: one with atrial septal defects and the other with patent ductus arteriosus. In both groups, percutaneous intervention was superior to surgery in terms of patient safety, with fewer immediate and long-term complications.

Survival and prognostic factors in patients with an absent atrioventricular connection.

Introduction And Objectives: To identify anatomical and functional characteristics associated with survival in adult patients with an absent atrioventricular connection and to highlight the diagnostic importance of echocardiography.

Methods: The clinical histories and echocardiographic and hemodynamic test results of 24 patients were recorded.

Results: Some 87.

[Tetralogy of fallot and total anomalous pulmonary venous drainage to coronary sinus. Case report].

We report the case of an infant 3 months old with a rare association, tetralogy of Fallot with total anomalous pulmonary veins connection the diagnosis was made by echocardiography and a successful complete reparation was achieved.

Treatment of seven patients with coarctation of the aorta treated using a Mexican-made platinum/iridium stent.

Background: Nowadays, stenting is the treatment of choice in patients >15 years of age with coarctation of the aorta without hypoplastic aortic isthmus. The platinum/iridium stent manufactured in Mexico may be an affordable alternative with the same benefits as the imported stent.

Methods: This is a series of cases in which we present the immediate results of the first seven patients with coarctation of the aorta treated with the platinum/iridium stent manufactured in Mexico.

[Patent ductus arteriosus in the adult: transcatheher treatment immediate and medium term results].

Introduction: The anatomic changes of the patent ductus arteriosus (PDA) in adult patients, such as aortic aneurysm, calcification, or being short and sometimes friable, could complicate the surgical treatment. The transcatheter occlusion of PDA with different devices is currently accepted as safe and effective. We presented our experience with percutaneous occlusion of PDA in adult patients by means of three different devices.

[Percutaneous closure of ductus arteriosus and muscular ventricular defect with amplatzer occluder in a patient with severe pulmonary hypertension].

Surgical treatment of multiple muscular ventricular septal defects with associated lesions and severe pulmonary hypertension has a high morbility and mortality. Closure of these defects by the Amplatzer muscular VSD occluder is an alternative to surgery, avoiding the need of cardiopulmonary bypass. We present the case of a 38 year-old woman with signs of heart failure in NYHA functional class IV, with two muscular ventricular septal defects, patent ductus arteriosus and severe pulmonary hypertension, that were treated with three Amplatzer muscular VSD occluders, with significant reduction of pulmonary pressure and functional class improvement.

[Usefulness of intracardiac echocardiography in interventional catheterization in congenital cardiopathies].

Intracardiac echocardiography is a new ultrasound image method that we are using during interventional cardiac procedures. Our experience began in June 2002 and until August 2003 we have treated 52 patients with atrial septal defect using this method as control tool for the procedure. This diagnostic method avoids the need for general anesthesia, achieves better views of the left heart structures, stretching balloon and device, and avoids the pharyngeal pain associated with the use of transesophageal probes.

[Septal defects treatment with Amplatzer occluders].

Since February 1999, we started the program to treat cardiac defects with Amplatzer occluders. We have treated 118 patients with atrial septal defect, 182 patients with patent ductus arterious, 11 with hypertensive arterial duct treated with the ventricular septal occluder, and 7 patients with ventricular septal defect. In this communication we detail our results with these devices.

[Repair of interatrial septal defect with an Amplatzer device. Experience with 3 cases].

We performed transcatheter closure of an atrial septal defect (ASD) using an Amplatzer device in three patients, 2 women and 1 male child, aged 12, 54, and 4 years, respectively, coursing with ostium secundum ASD. Two with left to right shunt and the third with bidirectional shunt. The transesophageal echocardiogram revealed ASD with diameters of 13, 15, and 10 mm, the diameter with expanded catheter balloon was of 30, 26, and 17 mm, respectively.
