Severe valvar aortic stenosis (VAS) and supravalvar aortic stenosis (SVAS) each may cause left ventricular (LV) subendocardial ischemia and infarction, even with patent coronary arteries. LV ischemia in VAS has been related to reduced coronary perfusion relative to raised metabolic requirements, whereas this mechanism of ischemia has not been widely accepted in SVAS because coronary perfusion p...

INTRODUCTION Stress cardiomyopathy is a condition of chest pain, breathlessness, abnormal heart rhythms and sometimes congestive heart failure or shock precipitated by intense mental or physical stress. CASE PRESENTATION A 64-year-old male with a known diagnosis of moderate-to-severe aortic stenosis and advised that valve replacement was not urgent, presented with acute pulmonary edema follow...

Pulmonary valvular stenosis with right-sided aortic arch and an intact ventricular septum is a rare anomaly. Brock and Campbell (1950) and Abrahams and Wood (1951) stated that the aortic arch was left-sided in simple pulmonary valvular stenosis. Three years later, Campbell (1954) reported one patient with a right aortic arch from a series of 75 cases of pulmonary valvular stenosis with an intac...

OBJECTIVE To determine the effect of systemic arterial hypertension on the indices of aortic stenosis (AS) severity. METHODS A severe supravalvar AS was created in 24 pigs. The maximum and mean pressure gradients across the stenosis were measured by Doppler echocardiography and by catheterisation. Both echocardiography and catheter data were used to calculate stenosis effective orifice area, ...

BACKGROUND Pulmonary artery intimal spindle cell sarcomas are rare and carry with them a poor prognosis and high rate of recurrence. In extremely rare cases, this tumor can infiltrate the pulmonic valve and manifest as adult-onset pulmonic stenosis. CASE PRESENTATION We report an unusual case of a patient with symptomatic, adult-onset severe pulmonic stenosis who was referred for possible bal...

Supravalvar mitral ring is a rare congenital heart defect of surgical importance. The condition is characterized by an abnormal ridge of the connective tissue on the atrial side of the mitral valve. It often substantially obstructs the mitral valve inflow. We herein introduce a case of a supravalvar mitral ring in a 17-year-old male, who was admitted to our hospital with cardiac syncope. He had...

We report here a successful case of balloon angioplasty for a stenosis of the pulmonary artery after lung transplantation. A 49-year-old patient with end stage diffuse bronchiectasis with sinusitis underwent bilateral living donor lobar lung transplantation. After treatment of postoperative right pneumothorax, a perfusion lung scan revealed deficient perfusion in the left lung. Pulmonary angiog...

OBJECTIVE To assess the efficacy of arterial duct angioplasty in maintaining adequate ductal patency in neonates with critical pulmonary valve stenosis. PATIENTS Two neonates presenting with cyanosis due to critical pulmonary valve stenosis with severe right ventricular hypoplasia underwent percutaneous balloon dilatation of the pulmonary valve. Despite successful dilatation, both remained cy...
