Respiratory failure is a serious complication of H1N1 influenza that, if not properly managed, can cause death. When mechanical ventilation is not effective, the only way to save the patient's life is extracorporeal membrane oxygenation (ECMO). A prolonged type of cardiopulmonary bypass, ECMO is a high-cost management modality compared to other conventional types and its maintenance requires skilled personnel. Such staff usually comprises the members of open-heart surgical teams. Herein, we describe a patient with H1N1 influenza and severe respiratory failure not improved by mechanical ventilation who was admitted to Masih Daneshvari Medical Center in March 2015...

Arash Gholoobi
The anomalous origin of the right coronary artery (RCA) as a branch from the left anterior descending artery (LAD) is a very rare variation of the single coronary artery anomaly. The anomalous vessel arises from the proximal or midportion of the LAD and courses anterior to the pulmonary artery trunk in most instances. In this case report, a 61-year-old woman is introduced who underwent coronary angiography following inferoposterior myocardial infarction, in which an anomalous RCA was seen originating from the midportion of the LAD...

The acute coronary syndrome due to the left main coronary artery (LMCA) thrombosis is a clinically rare and catastrophic event. We describe a young man (smoker, alcoholic, and drug abuser) with a history of recent surgery and typical chest pain who had non-occlusive LMCA thrombosis in coronary angiography. The thrombosis was successfully treated with two 180 µ/kg intracoronary boluses of eptifibatide, which was continued through an intravenous infusion at 2 µ/kg/min for 48 hours postprocedurally. Control angiography, performed 3 days later, revealed that the LMCA was free of thrombosis...

The Budd-Chiari syndrome (BCS) is a rare disorder caused by the obstruction of the hepatic veins or the inferior vena cava (IVC) at the suprahepatic level. This syndrome is developed by either hepatic vein thrombosis or mechanical venous obstruction and leads to centrilobular hepatic congestion with the subsequent development of fibrosis and cirrhosis. Intracardiac tumors have been rarely reported as a cause of the BCS. These tumors usually originate from the atrial septum. Very rarely, they arise either from the junction of the IVC and the right atrium or from the Eustachian valve...

Background: It is not clear whether the latest activation sites in the left ventricle (LV) are matched with infracted regions in patients with ischemic cardiomyopathy (ICM). We aimed to investigate whether the latest activation sites in the LV are in agreement with the region of akinesia in patients with ICM. Methods: Data were analyzed in 106 patients (age = 60.5 ± 12.1 y, male = 88.7%) with ICM (ejection fraction ≤ 35%) who were refractory to pharmacological therapy and were referred to the echocardiography department for an evaluation of the feasibility of cardiac resynchronization therapy...

Background: Hypertrophic cardiomyopathy is a genetic disorder with a prevalence rate of 0.2% in the general population. It comes from mutations in sarcomeric proteins. Cardiac myosin-binding protein C3 is one of the critical genes in hypertrophic cardiomyopathy (HCM) and sudden cardiac death, accounting for about 20% of HCM-causing mutations. Genetic testing is recommended in patients with HCM. The aim of the current study was to find possible disease-causing mutations in 3 exons of the gene myosin-binding protein C (MYBPC3) in patients with HCM...

Background: The late postoperative course for children with transposition of the great arteries (TGA) with an intact ventricular septum (IVS) is very important because the coronary arteries may be at risk of damage during arterial switch operation (ASO). We sought to investigate left ventricular function in patients with TGA/IVS by echocardiography. Methods: From March 2011 to December 2012, totally 20 infants (12 males and 8 females) with TGA/IVS were evaluated via 2-dimensional speckle-tracking echocardiography (2D STE) more than 6 months after they underwent ASO...

Spontaneous coronary artery dissection is a rare cause of acute coronary syndrome and sudden cardiac death. We report coronary artery dissection in a 36-year-old woman with retrosternal chest pain 2 weeks after abortion. Electrocardiography showed ST elevation in leads V2-V4 and ST depression in the inferior leads. Lab data were normal. Cardiac catheterization showed a suspicious thrombotic lesion at the proximal portion of the left anterior descending artery with a smooth contour consistent with distal haziness and dissection site...

Constrictive pericarditis (CP) is an uncommon post inflammatory disorder. It is described as pericardial thickening, myocardial constriction, and impaired diastolic filling. The most common etiologies are idiopathy, mediastinal radiotherapy, and prior cardiac surgery. Less common etiologies include viral infections, collagen vascular disorders, renal failure, sarcoidosis, tuberculosis, and blunt chest trauma. CP can less commonly be caused by malignancy. We report a very rare case of non-Hodgkin's lymphoma (NHL) presenting twice with attacks of decompensated heart failure...

Atrial septal defect (ASD) is a common congenital anomaly that has low surgical mortality and morbidity. We report a very rare case of a low-lying ASD, combined with the drainage of the inferior vena cava and the left superior vena cava into the left atrium. This combination was associated with an unroofed coronary sinus. We also describe an iatrogenic surgical diversion of the inferior vena cava into the left atrium with its complication. The patient presented with moderate cyanosis and was referred for elective ASD repair...

Surgery for heart diseases during pregnancy, especially necessitating cardiopulmonary bypass, is believed to trigger maternal and fetal risks and should be performed only when medical therapy has been unsuccessful to alleviate the cardiac decompensation. A 33-year-old pregnant woman in her 33rd week of gestation was admitted to our hospital. She had rheumatic mitral valvular stenosis and had undergone mitral valve replacement (MVR) with a mechanical prosthesis 11 years earlier in another center. Echocardiography revealed a thrombotic mass obstructing the leaflets of the mechanical mitral valve...

Background: Chronic wounds are a serious problem for the patient and can increase the socioeconomic burden on the healthcare system and community. This study aimed at investigating the effect of angioplasty on chronic ischemic wound healing. Methods: This study was conducted in Sina Hospital, affiliated to Tehran University of Medical Sciences. Thirty-eight patients with chronic ischemic wounds and a suspicion of the narrowing or blockage of arteries underwent peripheral angiography. Arteries under angioplasty in different patients comprised the aorta and the iliac, superficial femoral, popliteal, and tibial arteries...

Background: Delayed or missed diagnosis of critical and cyanotic congenital heart disease (CHD) in asymptomatic newborns may result in significant morbidity and mortality. The aim of this study was to determine the accuracy of pulse oximetry screening performed on the first day of life for the early detection of critical and cyanotic CHD in apparently normal newborns. Methods: This cross-sectional study used postductal pulse oximetry to evaluate term neonates born between 2008 and 2011 with normal physical examinations...

Background: N-terminal pro-brain natriuretic peptide (NT-proBNP) is a sensitive biomarker for the detection of asymptomatic left ventricular (LV) dysfunction. Since β-thalassemia major patients suffer from early diastolic dysfunction due to iron deposition of chronic blood transfusion, we tried to evaluate the correlation between the serum NT-proBNP level and the severity of LV diastolic dysfunction determined by echocardiography in these patients. Methods: Fifty β-thalassemia major patients with normal LV systolic function were studied by tissue Doppler echocardiography, and blood samples were taken at the same time to measure the serum NT-proBNP level...

Background: The biolimus-eluting stent (BES), with a biodegradable polymer, has not been previously compared with the everolimus-eluting stent (EES), as a second-generation drug-eluting stent (DES).We sought to compare the 1-year outcome between the PROMUS(™) stent (EES type) and the BioMatrix(™) stent (BES type). Methods: From March 2008 to September 2011, all patients treated with the PROMUS™ stent or the BioMatrix™ stent for coronary artery stenosis at Tehran Heart Center were enrolled. The primary end points were 1-year adverse events, comprising death, myocardial infarction, target vessel revascularization, and target lesion revascularization...

Background: Investigators frequently encounter continuous outcomes with plenty of values clumped at zero called semi-continuous outcomes. The Gensini score, one of the most widely used scoring systems for expressing coronary angiographic results, is of this type. The aim of this study was to apply two statistical approaches based on the categorization and original scale of the Gensini score to simultaneously assess the association between covariates and the presence and severity of coronary artery disease (CAD)...
