background anomalous left coronary artery from the pulmonary artery (alcapa) is a rare congenital cardiovascular defect that occurs in approximately 1/300 000 live births or 0.5% of children with congenital heart disease. there are two types of alcapa syndrome: the infant type and the adult type. the most infants experience myocardial infarction and congestive heart failure, and approximately 9...

Stress-induced cardiomyopathy, also known as 'broken heart syndrome' or Takotsubo cardiomyopathy, is characterized by transient systolic dysfunction of the apical and/or mid segments of the left ventricle, in the absence of significant coronary artery disease. We report the case of a 56-year-old male patient with chronic obstructive pulmonary disease (COPD), with stress-induced cardiomyopathy a...

OBJECTIVE To document cardiac abnormalities secondary to pulmonary disease in primary antibody deficiency. PATIENTS AND METHODS A cross sectional audit study of patients from a regional immunology centre. Subjects undergoing two dimensional and Doppler transthoracic echocardiography were reviewed. Ventricular dimensions and function, valvular competence, and estimated pulmonary artery pressur...

Obstructive sleep apnea syndrome (OSAS) leads to cardiovascular complications such as coronary artery disease, left/right ventricular hypertrophy and dysfunction, heart failure, systemic and pulmonary hypertension, arrhythmias and stroke; and these all cardiovascular complications increase morbidity and mortality of OSAS. However, Cheyne-Stokes respiration, central and obstructive apneas may oc...

We examined the function of the interventricular septum in six open-chest dogs by inserting piezoelectric crystals into the interventricular septum. Continuous ultrasonic recordings showed that the changes in myocardial chord length (MCL) in the septum and free walls of the right and left ventricle were similar during saline infusion and during pericardiotomy. End-diastolic MCL and myocardial s...

A previously unknown coronary artery anomaly is reported: origin of the left coronary artery from the right pulmonary artery. This unusual anomaly can probably be explained by the theory of dual embryonic development of the coronary arteries from angioblastic buds in the truncus arteriosus. It is thought that these buds anastomose with a capillary network that is developing on the surface of th...

LIE pulmonary second sound plays an important role in the clinical diagnosis of congenital and acquired heart diseases. Since phonocardiographic recordings from the chest wall present the pulmonary valve sound as part of a composite of sounds produced by 2 valves of the heart, it was our interest to demonstrate the pulmonary sound by direct phonocardiography. Cardiac sounds and murmurs heard an...

OBJECTIVES Altitude-hypoxia induces pulmonary arterial hypertension and altered cardiac morphology and function, which is little known in healthy children at high altitude. We compared the cardiopulmonary measurements between the healthy children at 16 m and those at 3700 m in China and between the Hans and the Tibetans at 3700 m. METHODS Echocardiography was assessed in 477 children (15 day-...

BACKGROUND: Univentricular congenital heart disease (CHD) is an anatomical defect where one of the ventricles does not develop. Management univentricular defects performed gradually; bidirectional cavopulmonary shunt (BCPS) surgical approaches conducted before definite treatment in Fontan procedure. Therefore, average rate pulmonary artery pressure and vasculature resistance critical factors de...
