Cardiac myxomas are the most common cardiac tumors with diverse nonspecific clinical manifestations. A 78-year-old man presented to the emergency department with complaints of pain and coldness of the left lower extremity. The left femoral artery pulse was detected, while the pulses of the left popliteal, dorsalis pedis, and posterior tibialis arteries were absent. No blood inflow was detected in the superficial and deep femoral, popliteal, and anterior and posterior tibialis arteries. Thrombectomy was performed, and a fatty-like mass from the bifurcation of the common femoral artery and a thrombotic mass from the proximal portion of the superficial and deep femoral arteries were removed...

Cardiac lipomas are extremely rare tumors of the heart. They are usually symptomatic and rarely may be found incidentally in autopsies. Here we describe a 23-year-old healthy man, in whose physical examination for employment a murmur was found incidentally. Transthoracic and then transesophageal echocardiographic examination showed a 4-cm oval-shaped mass in the right ventricular outflow tract. He underwent elective surgery, during which the tumor was removed under cardiopulmonary bypass and aortic-cross clamping via right atriotomy...

Ventricular septal defects (VSDs) are among the most common congenital cardiac lesions. Large defects at apicomuscular regions, especially in young patients, are far from accessible to surgeons for conventional surgery. Moreover, the transcatheter closure of VSDs in these patients is difficult and carries a high risk of complications because of the large sheath size relative to the patient's size. The periventricular approach simplifies VSD closure and, thus, eliminates the potential complications of cardiac catheterization and fluoroscopy as it is performed under echocardiographic guidance...

The pseudoaneurysm of the aorta is rarely due to trauma and infection but usually is a late complication of previous surgical procedures like coronary artery bypass graft surgery. We describe a 65-year-old woman with the pseudoaneurysm of the ascending aorta due to coronary artery bypass graft surgery. It was revealed in coronary artery angiography after nonspecific symptoms. It was confirmed by multidetector computed tomographic angiography. The patient refused open cardiac surgery, so we decided to use an atrial septal defect occluder device in off-label way to seal the pseudoaneurysm orifice...

The VACTERL association, co-occurrence of vertebral, anorectal, cardiac, tracheoesophageal, genitourinary, and limb malformations, is a rare congenital anomaly. Several cardiac anomalies have been reported as a part of the VACTERL association, particularly ventricular and atrial septal defects. Pulmonary artery sling is a rare congenital abnormality in which the left pulmonary artery arises from the right pulmonary artery. This anomaly is not frequently observed in the VACTERL association and has been rarely reported...

The anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly. The usual clinical course is severe left-sided heart failure and mitral valve insufficiency presenting during the first months of life. However, in some cases, the collateral blood supply from the right coronary artery is sufficient and symptoms may be subtle or even absent. We describe a 49-year-old woman presenting with atypical chest pain during physical exertion. The exercise tolerance test and then coronary angiography by indication revealed an anomalous origin of the left coronary artery...

Background: Hepatic lipase (HL) plays a crucial role in lipid metabolism, but there is debate about whether HL acts in a more pro- or more anti-atherogenic fashion. We aimed to examine the relationship between the -514 C/T polymorphism within the HL gene (LIPC) and the risk of angiographically determined premature coronary artery disease (CAD). Methods: Four hundred seventy-one patients with newly diagnosed angiographically documented (≥ 50% luminal stenosis of any coronary vessel) premature CAD were compared to 503 controls (subjects with no luminal stenosis in coronary arteries)...

Background: There are only a few reports concerning the genetic risk factors for coronary artery disease (CAD). However, 2 polymorphisms of rs10757274 and rs2383206 on chromosome 9p21.3 have been shown recently to be associated with CAD in certain populations. This is the 1st study to investigate their validity and association with CAD in a sample of the Iranian population. Methods: Genomic DNA was extracted from the peripheral blood of all participants, consisting of 111 cases with CAD and 100 normal controls with normal coronary angiographies...

Background: Several studies have emphasized the importance of cardiovascular disease (CVD) prevention. However, there is a dearth of data on the prevention of cardiovascular disease recurrence. The present study was the 1st in Iran to evaluate factors associated with CVD recurrence. Methods: This prospective cohort study was conducted on 483 subjects (> 30 years old) with a history of CVD who participated in the Tehran Lipid and Glucose Study and were followed up for 12 years (1999-2012). The relationships between the most important established risk factors for CVD and CVD recurrence were evaluated...

Radiation risk allied to invasive cardiology is relatively high, and protecting both patients and cardiologists is necessary. The aim of this review is to discuss how to better protect patients and cardiologists against radiation exposure. We performed a global search on PubMed, Science Direct, and Scopus databases via keywords of "interventional cardiologist", "patient", "radiation", and "exposure" and then performed an overview of the main strategies for risk reduction among interventional cardiologists and exposed patients...

Takotsubo or stress-induced cardiomyopathy is a cardiomyopathy in which the patient has a sudden onset, reversible left ventricular systolic dysfunction without any significant coronary artery disease. Four women, who were at a mean age of 64 years and suffered from chest pain exacerbated by emotional stress, were admitted as cases of acute coronary syndrome and were completely evaluated through precise history taking, physical examination, and ECG. Coronary angiography or coronary multidetector computed tomography was used to exclude significant coronary artery disease...

Seyed Mohsen Mirhosseini, Ali Sanjari Moghaddam
Major complications of heart transplantation include graft rejection, infection, graft arteriosclerosis, malignancy, and drug toxicity. Among these complications, infections and thrombophilic disorders are of particular interest owing to their major contribution to morbidity and mortality among heart transplantation patients. Thrombophilic disorders are caused by imbalance between hypercoagulation and fibrinolytic states. In this report, we describe a 43-year-old man who had unusual complications of heart transplantation...

Traumatic injuries to the subclavian-axillary artery, although uncommon, are associated with high morbidity and mortality rates if not managed promptly. The emergence of endovascular techniques offers an alternative to the surgical management of these injuries. We herein present 4 cases of traumatic subclavian-axillary artery injury with limb ischemia successfully managed via the endovascular approach with non-covered self-expandable stents. We achieved excellent immediate results with limb salvage and without complications...

The coronary slow flow phenomenon (CSFP) is characterized by a delayed coronary blood flow in the absence of an obstructive coronary artery disease. Although the relation between the CSFP and myocardial ischemia has been reported previously, there is no knowledge about the relationship between the CSFP and the conduction system disorder. In this case report, we describe a patient with the CSFP presenting with complete heart block (CHB). The patient was a middle-aged woman with a history of diabetes, hypertension, and prior Coronary Care Unit admission presenting with dizziness, lightheadedness, and presyncope...

Reza Ghanavati, Mehran Arab Ahmadi, Behdad Behnam
Transradial coronary angiography has been known as an alternative to the transfemoral approach with fewer serious complications. Radial artery pseudoaneurysms present as a rare complication of transradial catheterization. Although some methods have been applied for the obliteration of pseudoaneurysms, the use of radial bands such as the TR Band(®) (Terumo Medical Corporation, Somerset, NJ) is a novel efficient technique only suggested by a few reports. We describe a 34-year-old man, who underwent transradial primary coronary angiography due to ST-elevation myocardial infarction...

Background: The C1019T polymorphism of the connexin-37 (GJA4) gene is a single-nucleotide polymorphisms involved in atherosclerotic plaque rupture and atherosclerosis predisposition. We examined the association between the C1019T polymorphism of the GJA4 gene and the occurrence of myocardial infarction (MI) in patients with premature coronary artery disease (CAD). Methods: Our study recruited 1000 patients with the final diagnosis of premature CAD and classified them into 2 groups: with a history of MI (n = 461) and without it (n = 539)...

Background: Myocardial infarction is the main cause of death worldwide. Angiogenesis, a promising new therapy for the treatment of diffuse coronary artery disease, shows a poor response to conventional revascularization techniques. This study focused on improving myocardial function using endothelial cells (ECs) and mesenchymal stem cells (MSCs) in a sheep animal model. Methods: Acute myocardial infarction was induced in 18 sheep (12 treated cases and 6 controls). Autologous MSCs and ECs were injected in the infarcted area and the border zone...

Background: L-carnitine may prevent the incidence of AKI by its antioxidant effects and improving circulation in ischemic conditions. The goal of this trial was to evaluate the impact of L-carnitine on contrast-induced nephropathy in patients undergoing elective PCI. Methods: Totally, the patients were randomly allocated to 2 groups. The treatment group received 1 g of L-carnitine orally 3 times a day, 24 hours before the procedure (3 g before PCI) and 2 g after PCI, whereas the control group did not receive L-carnitine...

Heart failure (HF) is one of the main causes of death and disability in the world. The prevalence of HF in developed countries is between 1% and 2% of the adult population and approximately between 6% and 10% in the elderly, giving rise to high costs of care and treatment. Indeed, in the United States, the direct and indirect costs exceeded 23 billion dollars in 2002. HF is typically characterized by periods of acute symptoms followed by returns to nearly asymptomatic periods. As dyspnea and fatigue are considered the signature symptoms of HF, other symptoms such as pain go unnoticed...
