Iranian Society of Cardiac Surgeons COVID-19 task force version II, restarting elective surgeries.

Given the nature of heart disease and the importance of continuing heart surgery during the pandemic and its aftermath and in order to provide adequate safety for the surgical team and achieve the desired result for patients, as well as the optimal use of ICU beds, the medical team, blood, blood products, and personal protective equipment, it is essential to change the usual approach during the pandemic. There are still a lot of evidences and experiences needed to produce the perfect protocol. Some centers may have a special program for their centers during this period of epidemics that can be respected and performed.

Hysteroscopic tissue removal systems for the treatment of intrauterine pathology: a systematic review and meta-analysis.

Background: The use of mechanical tissue removal systems is more frequently implemented as the first line approach for the treatment of intrauterine pathology. Scientific evidence is provided that their use is easier and faster than the conventional resectoscope. It is necessary to objectively evaluate the results on tissue removal systems for the treatment of endometrial pathology as the reports in the literature are still conflicting.

Mitral valve-in-valve replacement supported by a transapically snared guidewire via septostomy.

We describe a 72-year-old woman, a known case of rheumatic heart disease with a history of mitral and aortic valve replacement 8 years previously, who underwent mitral valve-in-valve replacement supported by a transapically snared guidewire through septostomy.

The 19 Fr. Intrauterine Bigatti Shaver (IBS®): a clinical and technical update.

In this case report we describe the first two surgeries conducted with the 19 Fr. IBS®. The indication for operative hysteroscopy in both patients was the removal of polyps.

Operative hysteroscopy with the Bigatti shaver (IBS ®) for the removal of placental remnants.

Background: About 15-20% of pregnant women will miscarry spontaneously during the first trimester. Traditionally, the surgical treatment of placental remnants has been dilation and curettage (D&C). However, because of its 'blind' nature there is a risk of serious complications, such as infection, adhesion, uterine perforation, or bowel injury.

Single-session double valve replacement: TAVI+tricuspid valve-in-valve procedures.

We describe a 70-year-old lady with rheumatic heart disease and a history of the mitral valve and tricuspid valve replacement, who underwent transcatheter aortic valve implantation and the tricuspid valve-in-valve procedure in a single session.

Rebalancing the Vestibular System by Unidirectional Rotations in Patients With Chronic Vestibular Dysfunction.

Vestibular dysfunction is a common disorder that results in debilitating symptoms. Even after full compensation, the vestibulo-ocular reflex (VOR) could be further improved by using rehabilitation exercises and visual-vestibular adaptation. We hypothesized that in patients with asymmetric vestibular function, the system could be rebalanced by unidirectional rotations toward the weaker side (i.

Hypermethylation pattern of ESR and PgR genes and lacking estrogen and progesterone receptors in human breast cancer tumors: ER/PR subtypes.

Background: The option of endocrine therapy in breast cancer remains conventionally promising.

Objective: We aimed to investigate how accurately the pattern of hypermethylation at estrogen receptor (ESR) and progesterone receptor (PgR) genes may associate with relative expression and protein status of ER, PR and the combinative phenotype of ER/PR.

Methods: In this consecutive case-series, we enrolled 139 primary diagnosed breast cancer.

Complex Ebstein's Anomaly in an 86-Year-Old Iranian Man: A Case Report.

Ebstein's anomaly is defined as the significant apical displacement of the tricuspid valve causing tricuspid regurgitation. Although a variety of concomitant lesions have been previously described, we herein introduce an unusual presentation. Our patient was an 86-year-old man with a primary presentation of typical chest pain in the setting of recently diagnosed coronary artery disease with concomitant Ebstein's anomaly.

Conservative Management of Left Atrial Intramural Hematoma after Catheter Ablation.

Left atrial intramural hematoma is a very rare complication of radiofrequency ablation procedures. A patient with tachyarrhythmia underwent radiofrequency catheter ablation. Echocardiography performed the following morning showed a large mass in the left atrium, suggestive of intramural hematoma formation.

Replacement of a Dislocated Aortic Prosthesis After Transcatheter Valve Implantation.

A 77-year-old woman who had severe symptomatic aortic stenosis and was a high risk for conventional surgery underwent transcatheter aortic valve implantation by means of the transfemoral approach. The prosthesis migrated and became embolized in the left ventricle after inflation, causing interference with the mitral valve and also partial outflow tract obstruction. The patient was emergently transferred to the operating room.

Length of second-order chordae as a predictor of systolic anterior motion of the mitral valve.

Objectives: The aim of the present study was to ascertain whether the length of anterior mitral leaflet second-order chordae (SOC) could be considered as a predictor of the incidence of post-repair systolic anterior motion (SAM) and left ventricular outflow tract obstruction (LVOTO) in patients with myxomatous mitral valve disease.

Methods: With the implementation of preoperative transoesophageal echocardiography (TEE), the length of anterior mitral leaflet SOC, anterior leaflet (AL) and posterior leaflet (PL) as well as the distance from the coaptation point to the septum (C-S distance) before and after mitral valve repair (MVR) surgery were measured in 190 patients, comprising 12 who developed SAM and 178 who did not.

Results: The results revealed that, in patients who developed SAM, SOC were significantly higher (2.

Simultaneous Detection and Genotype Determination of HSV 1 and 2 by Real-time PCR Using Melting Curve Analysis and a Unique Pair of Primers.

Herpes simplex virus (HSV) is a human pathogen that causes different pathologic manifestations. Rapid and feasible detection and discrimination methods for HSV genotyping is a challenge in clinical laboratories, especially in children suffering from herpetic encephalitis. A quantitative real-time polymerase chain reaction (PCR)-based genotyping assay using SYBR Green I was established.

Spontaneous complete regression of hypothalamic pilocytic astrocytoma after partial resection in a child, complicated with Stevens-Johnson syndrome: a case report and literature review.

Pilocytic astrocytoma (PA) is the most common pediatric central nervous system glial neoplasm and the most common pediatric cerebellar tumor. The spontaneous regression that occurs after partial/subtotal resection is multifactorial, depending on multiple factors, as for the case of humoral and cell-mediated immune responses of the host to the implanted tumor. A 7-year-old boy was referred to a neurosurgery clinic with headache.

Smoking and wound complications after coronary artery bypass grafting.

Background: The harmful effects of smoking on the postsurgical wound healing disturbances have been widely investigated across various surgical procedures. These effects after coronary artery bypass graft (CABG) surgery have been less explored. We aimed to investigate the association of smoking and the wound healing problems in post-CABG patients.

Heart and Lung Metastases From Endometrial Stromal Sarcoma in a Forty-Two-Year-Old Woman.

Introduction: Low-grade endometrial stromal sarcoma (LG-ESS) is a malignant intrauterine tumor that rarely presents with distant metastasis. Simultaneous lung and cardiac metastases from LG-ESS is also an extremely rare event.

Case Presentation: A 42-year-old woman presented with dyspnea and exercise intolerance.

Right-sided cervical aortic arch in Loeys-Dietz syndrome.

Loeys-Dietz syndrome is an autosomal dominant connective tissue disorder that is characterized by skeletal abnormalities, craniofacial malformations, and predisposition for aortic aneurysm with tortuosity. We report a case of a right-sided cervical aortic arch associated with the Loeys-Dietz syndrome. To the best of our knowledge, this combination has not been described in the literature.

Giant left atrial aneurysm.

Congenital aneurysmal dilatation of the left atrium is a rare anomaly that could be associated with supraventricular arrhythmias and life-threatening systemic embolization. We describe a 32-year-old man with a giant left atrial aneurysm diagnosed with new imaging modalities that underwent surgical resection with good results. < Left atrial aneurysms are rare and characterized by their origin from an otherwise normal atrium, a clearly defined communication with the atrial cavity, and their intrapericardial location.

The value of coronary artery calcium score assessed by dual-source computed tomography coronary angiography for predicting presence and severity of coronary artery disease.

Background: Measuring coronary artery calcium score (CACS) using a dual-source CT scanner is recognized as a major indicator for assessing coronary artery disease. The present study aimed to validate the clinical significance of CACS in predicting coronary artery stenosis and its severity.

Material/methods: This prospective study was conducted on 202 consecutive patients who underwent both conventional coronary angiography and dual-source (256-slice) computed tomography coronary angiography (CTA) for any reason in our cardiac imaging center from March to September 2013.

Aortic root replacement using a modified composite valve graft.

Objectives: We used a modified technique of a composite graft by moving the valve prosthesis away from the end into the inside of the tube and compared the effectiveness of this surgical method with the standard valved conduits.

Methods: Through a prospective nonrandomized clinical study between March 2011 and June 2012, we performed replacement of the aortic valve and ascending aorta in 30 consecutive patients using a valved composite graft with a mechanical valve prosthesis. A modified self-assembled valved composite graft was employed in 20 patients (Modified group), while the remaining 10 patients received the standard composite graft (Control group).

Estimating the Myocardium's Angle of Three-Dimensional Trajectory, Using the Tracking of Sequential Two-Dimensional Echocardiography Images.

Background: In this study, the angle of the myocardium's trajectory in three dimensions (ф) was estimated by simultaneous use of long-axis and short-axis views of left ventricle septum two-dimensional images. Then correlation of three-dimensional trajectory's angle with the rotation angle from the long (χ) and short (θ) axis views was estimated and compared at the three levels of base, mid and apex of the interventricular septum wall.

Methods: Two-dimensional echocardiography images of long- and short-axis views of 19 healthy men were recorded and analyzed.
