Background: Residual false channel is common after repair of type A acute aortic dissection (TAAAD). Starting from our recent series of TAAAD patients we carried out a retrospective analysis, regarding the failure of primary exclusion at the time of the initial operation. We classified the location of the principal entry tears perfusing the residual false channel. The proposed technique represents our attempt to correct the mechanism of false channel perfusion during primary repair. We describe a new technique designed to address some limitations of standard hemiarch aortic replacement...

We encountered a case of retroaortic left renal vein (RLRV) during an anatomical dissection course at our medical school in 2017. The case was a female cadaver who was 88 years old at death. Six roots of the left renal vein (RV) arose from the hilus of the kidney and joined to form one left renal vein, crossed dorsal to the abdominal aorta (AA) at the level of the second lumbar vertebra, and then drained into the inferior vena cava (IVC). Two roots joined at the right renal hilus to become the right RV to then drain into the IVC at the level of the first lumbar vertebral body...

Reoperations on the proximal thoracic aorta represent a challenge. The mortality rate is at least three times higher than it is for the initial surgery and the complications after such procedures occur with disappointingly high frequency, leading to substantial morbidity and delayed recovery. This article aims to present the early and the late outcomes of these kinds of operations, to identify the causes for failure of the primary surgery, to underline the critical points during the perioperative management of those patients and finally to emphasize on the rapid evolution and advent of techniques over the last few years...

BACKGROUND:  Post-coarctation of the aorta (CoA) pseudoaneurysms is a complication of open repair. Thoracic endovascular repair (TEVAR) is feasible but complicated by proximity to the supra-aortic trunks and severe arch angulation. METHODS:  We describe three cases of post-CoA pseudoaneurysms treated with custom-made Relay stent grafts (Vascutek, Scotland). RESULTS:  Technical and clinical success was achieved in all three cases with no mortality, morbidity, endoleaks, or complications...

One of the most complex forms of congenital heart disease (CHD) involving single ventricle physiology is hypoplastic left heart syndrome (HLHS), characterized by underdevelopment of the left ventricle (LV), mitral and aortic valves, and narrowing of the ascending aorta. The underdeveloped LV is incapable of providing long-term systemic flow, and if left untreated, the condition is fatal. Current treatment for this condition consists of three consecutive staged palliative operations: the first is conducted within the first few weeks of birth, the second between 4 to 6 months, and the third and final surgery within the first 4 years...

BACKGROUND: Flow measurements using cardiac magnetic resonance imaging (CMRI) enable quantification of the stroke volume, regurgitant volume (RV) and regurgitant fraction (RF) in patients with aortic regurgitation (AR). These variables are used to assess the severity of the valve disease and for the timing of surgery. The aim of the study was to investigate the impact of an increased heart rate on measurement of the RV and RF in patients with AR. METHODS: Among 13 patients with known moderate or severe AR, regurgitant flow measurements, using phase-contrast cine magnetic resonance imaging, were obtained in the ascending aorta...

INTRODUCTION: In coronary bypass surgery, after cardiopulmonary bypass is initiated by arterial cannulation in the ascending aorta and venous cannulation through a single vein generally in the right atrium, the process of cooling the patient is started. There is a relation between cooling the patient and irisin, which is responsible for releasing heat. OBJECTIVE: Therefore, the main objective of the present study is to explore how irisin concentrations and some other panel of myocardium injury in patients undergoing coronary artery bypass surgery changes...

Studies showed that physical exercise decreases the risk of developing Parkinson's disease (PD) as slowing its progression. During aerobic training, nitric oxide (NO) increases in the substantia nigra pars compacta (SNpc) of individuals with PD. However, no study has evaluated the effects of exercise on peripheral NO levels and its modulatory effects on cardiovascular dysfunctions of subjects with PD. Trained (T) or sedentary (S) animals underwent stereotactic surgery for bilateral 6-hydroxydopamine (6-OHDA) or vehicle microinfusion (Sham group)...
