Coronary artery fistulae (CAF) are direct precapillary communications which bypass the myocardial capillary network and connect a coronary artery to another vessel or cardiac chamber (cameral).1 CAF are reported in 0.1–0.7% of patients undergoing cor…
Percutaneous occlusion of a patent ductus arteriosus (PDA) is actually a standard procedure for the treatment of this congenital heart defect. Different devices have been used for the last 20 years with high rates of success.1,2,4,8,11,13,14 A few ex…
Complete heart block (CHB) due to the loss of a first septal perforator (FSP) following left anterior descending artery (LAD) stenting is uncommon, with few reported cases in the literature.1,2 It usually occurs at the time of the procedure and is tr…
Percutaneous intervention of chronic total occlusions (CTOs) can improve exercise capacity, symptoms and left ventricular function.1 The parallel wire technique is a useful technique in recanalizing CTOs.2 This technique utilizes a second wire to cro…
Case Report. A 37-year-old female in her seventh week of pregnancy presented to the emergency department after the onset of oppressive chest pain which had started 1 hour before. Her 8 previous pregnancies had terminated in abortion. She had no card…
Percutaneous left ventricular (LV) assist devices are increasingly being used during high-risk percutaneous coronary interventional (PCI) procedures.1–4 These devices provide reliable short-term hemodynamic stability in complex cases during which the…
Case Report. A 64-year-old male was transferred from an outside facility after sustaining a non-ST-elevation myocardial infarction (STEMI). Cardiovascular risk factors included noninsulin- dependent diabetes mellitus and hypertension. Additionally, h…
Provisional stenting is the most widely used method for the treatment of bifurcation coronary artery lesions. It consists of the placement of the first stent in the main branch, followed by provisional stenting of the side branch through the main bra…
Variant angina is more frequently seen in East Asia than in the West. It may be associated with acute myocardial infarction, severe cardiac arrhythmia and sudden death. Most patients obtain sufficient relief by vasodilator drug management such as cal…
The undilatable lesion requiring rotational atherectomy is an uncommon occurrence with the current availability of noncompliant balloons and other methods of “focused-force” angioplasty. The use of noncompliant balloons, or a “buddy” cutting wire, an…
