The objective of this study is to investigate pre-intervention IVUS characteristics of in-stent restenosis (ISR) lesion correlated with PEB failure. We performed pre-intervention IVUS for 58 patients with ISR and treated with PEB angioplasty. The PEB failure was defined as death, myocardial infarction and symptom driven revascularization. IVUS images were analyzed at 6 locations: Proximal and distal vessel segment within 3 mm from stent edge, proximal and distal stent edge, lesion site at minima...
Evaluation of Hemodynamic Behavior of a Stentless Aortic Bioprosthesis under Stress by Exercise Echocardiography

Aim of this study was to evaluate by transthoracic echo the hemodynamic behaviour and the changes in dimensional data of a stentless aortic bioprosthesis between rest and exercise conditions. se of exercise echocardiography to assess changes in hemodynamics and function of aortic bioprostheses can be helpful in the choice of appropriate aortic valve substitutes. SPF pericardial stentless valve presents favourable and durable hemodynamic characteristics at rest and on exercise, similar to native ...
The Profile of an Adult with Congenital Heart Disease

Article Type: Short Review | First Published: December 01, 2018
Congenital heart disease is the most frequent malformation. In the most recent data has a prevalence of thirteen cases per 1,000 children and six cases per 1,000 adults. Great strides in pediatric cardiovascular surgery have increased the number of survivors, especially in adulthood. Nowadays more adults are living with congenital heart disease than children, particularly in developed countries, and more than two thirds fall into the categories of moderate and high complexity defects. This growi...

Article Type: Case Report | First Published: November 12, 2018
Carotid sinus syndrome (CSS) is defined as syncope with reproduction of symptoms during 10s of carotid sinus massage. The etiology of this condition is unknown, patients are usually symptomatic and present with episodes of syncope. Due to the associated marked sinus bradycardia, sinus arrest or severe hypotension, carotid sinus syndrome may be life-threatening. In patients without previous symptoms, CSS must be promptly recognized and treated, otherwise may lead to catastrophic consequences. If ...

Cerebral protection is a big technical difficulty for aortic surgery. Increased use of antegrade cerebral perfusion (ACP) and deep hypotermic circulatory arrest in experienced hands made open surgery of the ascending aorta and aortic arch aneurysms more successful today. The increase in the variety of surgical equipment to provide unilateral and bilateral cerebral perfusion or monitorization, the effectiveness of the cerebral protection instantly decreased the risk of perioperative stroke or pos...
Measurement of the QT Interval: Lessons from Thirty-Two Animal Species for the Correction of the QT Interval by Heart Rate
Simon W Rabkin
Article Type: Review Article | First Published: November 07, 2018
The optimal method to correct the QT interval, an important indication of arrhythmia risk, for the impact of heart rate has been controversial. The fundamental biologic relationship of the QT interval-heart rate relationship has rarely been studied across different species. The literature on the QT and heart rate of 32 different species was examined specifically in the whales, dolphins, Asian elephants, rhinoceros, camels, brown bears, grizzly bear, lions, tigers, sea lions, seals, donkeys, poni...
Takotsubo Stress Syndrome and Intracoronary Thromboembolic Occlusion: Fact or Myth?
Article Type: Case Report | First Published: October 24, 2018
A few case reports found an association between left ventricular apical ballooning and transient thromboembolic occlusion in myocardial bridging of the mid-portion left anterior descending coronary artery. In two additional, so far unpublished case reports distal or mid-portion thromboembolic occlusion of the left anterior descending coronary artery and the first diagonal branch were described. Both cases had a tragic outcome-either due to myocardial perforation or disseminated intravascular coa...
