Hypertrophic cardiomyopathy is one of the major causes of cardiac death that affects 1 in every 500 persons worldwide. Surgical myectomy and alcohol septal ablation have been the gold standard well established procedures for the treatment of this condition. Starting 2004 a new procedure, radiofrequency septal ablation, has been applied and showed significant improvement in the NYHA classification as well as the left ventricular outflow tract (LVOT) gradients of these patients. With overall less ...

A middle-aged Caucasian woman presented with an ascending aortic pseudoaneurysm (AAP) located at the suture site of her previous surgical dissection repair. The pseudoaneurysm was located along the anterior aspect of the ascending thoracic aorta, above the right coronary cusp. We demonstrate successful percutaneous repair of the pseudoaneurysm using a ventricular septal occluder (VSO) and discuss the significance of this procedure for future cardiovascular care. A 56-year-old Caucasian woman wit...

Pericardial effusions (PE) in patients with Down syndrome (Trisomy 21) have been associated with hypothyroidism, viral infections and malignancies (particularly leukemia). The PE is usually not large enough to cause cardiac tamponade. We report two cases of idiopathic large PE with one of them progressing to develop a cardiac tamponade that required an urgent pericardiocentesis. A 3-year-old female with Trisomy 21 was seen at cardiology clinic for follow up of a small secundum ASD. Patient has b...

Atrial fibrillation (AF), not to be confused with atrial flutter, is the term used to describe an irregular or abnormal heart rate. While AF and atrial flutter are similar, AF has more serious health implications such as an increased risk of having a stroke or a blood clot (thrombosis). The resting heart rate of someone without AF is usually between 60 and 100 beats per minute but this number is usually over 100 in AF. It is usually the result of an underlying condition such as hypertension (hig...
