Maryam Nabati, Mozhdeh Dabirian
Congenitally corrected transposition of great arteries (CCTGA) is a rare anomaly described by atrioventricular and ventriculoarterial discordance. On the other hand, mesocardia that is extremely rare includes two relatively well-defined apexes defined by each ventricle with the major axis of the heart lies in the midline. We describe a rare case of an asymptomatic 20-year-old woman with mesocardia, CCTGA, and severe subvalvular pulmonic stenosis due to a ball-shaped accessory tissue in left ventricular outflow tract...

In cases with significant pericardial effusion, cardiac apical swinging is a characteristic finding, usually detected by echocardiography and electrocardiography. We present a case showing typical cardiac apical swinging, initially detected by routine computed tomography as a cardiac swinging artifact. The present case highlights the importance of multidisciplinary interpretation of cardiac images, specifically focusing on the difference between static images obtained by computed tomography and dynamic images visualized by echocardiography...

Ventricular septal rupture is a serious complication following acute myocardial infarctions and is associated with a significant mortality rate. Classically, two-dimensional transthoracic echocardiography has been used to diagnose this complication and visualize its location. Two-dimensional transesophageal echocardiography has supplemented the transthoracic approach by providing more accurate assessment of the defect size and in guiding closure both percutaneously and intraoperatively. This modality, however, is limited to two-dimensional views only, and a greater breadth of information is instead available through the use of three-dimensional transesophageal echocardiography...

A 19-year-old male patient was admitted to our institute with dyspnea. His medical history had no rheumatic fever or infective endocarditis. Physical examination revealed a diastolic murmur over the aortic area, rales of bilateral lungs. Bedside transthoracic echocardiography (TTE) revealed a severe aortic regurgitation (AR) without aortic valve stenosis and a moderately dilated left ventricle accompanied by an ejection fraction of 55%. The aortic valve could not be clearly demonstrated as either bicuspid or tricuspid...

An asymptomatic 45-year-old man was referred to our hospital for detailed evaluation of a systolic ejection murmur. The intensity of the murmur increased on deep expiration and decreased on deep inspiration, showing so-called reversed Rivero-Carvallo's sign. Using cardiac magnetic resonance imaging, we demonstrated a characteristic respiratory-induced change in peak flow velocity in the right ventricular outflow tract, which was the basic mechanism of the reversed Rivero-Carvallo's sign in a case with straight back syndrome...

Papillary muscle (PM) rupture is a rare complication of acute myocardial infarction which carries an excessive mortality rate. Optimal outcomes require rapid diagnosis and prompt surgical referral, and in this regard, echocardiography plays a crucial role. Comprehensive echocardiographic examination of the patient with PM rupture consists of identification of the ruptured PM segment, visualization of flail mitral valve segment(s), evaluation of mitral regurgitation severity, and assessment of left ventricular systolic function...

As an uncommon multisystem inflammatory disease, Behçet's syndrome is characterized by mouth and genital ulcers, skin lesions, and eye inflammation, which may also affect joints, blood vessels, central nervous system, or digestive tract. However, the inflammation of coronary artery is relatively rare. We thereby reported a young male of Behçet's syndrome presenting left anterior descending artery pseudoaneurysm with myocardial infarction. Surgical resection was performed with coronary bypass grafting.

This report concerns an 83-year-old woman with aortic stenosis (AS) who had a history of repetitive hospitalization due to decompensated heart failure. Although her clinical history was compatible with significant AS, findings for aortic valve area, hemodynamics, and valvular calcium burden were discrepant. Multiplanar reconstruction images revealed the membranous structures attached to a subcommissural lesion, which resulted in severe stenosis. The patient had a favorable clinical course after transcatheter aortic valve replacement...

The direct abnormal drainage of the inferior vena cava (IVC), while rare, is well-recognized anomaly of systemic venous drainage. It has been reported both in isolation and in association with other cardiac defects. This is a case of an abnormal drainage of IVC into left atrium (LA) together with partial abnormal pulmonary venous drainage to the right atrium (RA) and atrium septal defect (ASD).
