The effects of beta–blockers in pediatric and congenital heart disease (CHD) patients suffering from heart failure are controversial. We performed a meta–analysis to determine whether beta–blockers are effective for heart failure in pediatric and CHD patients.

Transradial access has nowadays become a standard of care for percutaneous coronary angiography and intervention. This approach has demonstrated significant reduction in bleeding rate, length of hospital stay, and improvement in clinical outcomes when compared to the traditional transfemoral approach. Due to its advantages this new access is also increasingly being used in non-coronary visceral or peripheral interventions. However, this novel approach may lead to severe catheter kinking and twisting and further manipulation may be required to unravel the catheter and avoid complication. Purpose of this technical review is to present the current techniques and trends in preventing and resolving issues related to radial access catheter kinks.

Palliative care is an alternate therapeutic approach that involves specialized medical care of a patient diagnosed with serious life threatening illness like heart failure. The prime aim of the palliative care is to provide patient with relief from the symptoms, pain, physical stress, and mental stress of the diagnosed disease. The palliative care helps in improving the quality of life for both the patient and the family. Advanced heart failure (HF) is a disease process that carries a high burden of symptoms, suffering, and death. Palliative care can complement traditional care to improve symptom amelioration, patient–caregiver communication, emotional support, and medical decision making. The present review summarized all the available on alternative palliative approaches provided to heart patient by a team of physicians , nurses and other healthcare professionals.

The efficacy of RADPAD ® (a sterile, lead–free drape) has been demonstrated to reduce the scatter radiation to the primary operator during fluoroscopic procedures. However, the use of the RADPAD ® during TAVI procedures has not been studied. Transcatheter Aortic Valve Implantation (TAVI) is now an established treatment for patients with symptomatic severe aortic stenosis who are deemed inoperable or at high risk for conventional surgical aortic valve replacement (AVR). Consequently the radiation exposure to the patient and the interventional team from this procedure has become a matter of interest and importance. Methods to reduce radiation exposure to the interventional team during this procedure should be actively investigated.

Chronic increase in left ventricular filling pressure represents one of the most important mechanism underlying the structural, as well as the electrical, atrial chamber remodeling leading to atrial fibrillation. The present pilot pathophysiological study sought to investigate possible relationship between short–period cross–spectral coherence of P–Q, R–R and P–P intervals and echocardiographic indices of left ventricular and atrial function.

This study aimed to analyze the correlations between anterior wall motion velocity of ascending aorta measured by quantitative tissue velocity image (QTVI) technique and left ventricular geometry as well as left heart function to evaluate its value of clinical application.

A new controversy is raising in cardiovascular surgery, whether or not the new generation transcatheter valves used for valve implantation are superior to surgical techniques used for traditional valve replacement. If such a debate is far from being an issue for mitral valve treatment, where minimal invasive, (robotic or video-assisted) mitral valve repair has become the gold standard for mitral valve treatment while transcatheter mitral valve solutions are lagging behind(1-4), there are many voices stating that the future of aortic valve treatment will mainly be transcatheter(5).

Stentless aortic valves have been developed to overcome obstructive limitations associated with stented bioprostheses. A new concept of surgical sutureless (SU) bioprosthesis has been developed in the last decade. In this multi-institutional study we sought to compare hemodynamics of different bioprosthesis concept as transcatheter (TAVR), Livanova Perceval S sutureless valve and Freedom Solo Stentless (FS) valve in patients undergoing aortic valve replacement (sAVR).

Aortic valve replacement with biological heart valves remains the gold standard for treating operable older patients with symptomatic aortic stenosis. In the last years trans aortic valve implantation (TAVI) has been shown to be superior to medical treatment in high risks patients with severe aortic stenosis. The transfemoral TAVI route has been also found in randomized controlled trials to be as good if not superior to standard AVR at 5 years in high risk patients. In intermediate risks patients TAVI was found in randomized controlled trials as a noninferior alternative to surgery, with a different pattern of adverse events associated with each procedure. In retrospective propensity matched analysis the use of TAVI in patients with an intermediate to high risk profile was associated with a significantly higher incidence of perioperative complications and decreased survival at short and mid-term when compared with conventional surgery and sutureless valve implantation. More data is needed to draw a firm conclusion comparing the two treatments in intermediate risk patients. Sutureless bioprosthesis may represent a viable alternative to standard bioprosthesis for intermediate and high risks patients when having conventional surgery.

Development of new atherosclerotic lesions within the neointima of stented vessels has been recognized as a novel disease manifestation of atherosclerosis (neoatherosclerosis), often manifesting as in-stent restenosis (ISR) or in-stent thrombosis (ST). The pathobiology of this entity is still not fully understood and definite diagnosis is challenging owing to limitations in resolution of contemporary intravascular imaging modalities and lack of consequent histopathology correlation studies. Yet, intravascular imaging has emerged as the gold standard for the diagnosis of in-stent pathologies, the most routinely used modalities being intravascular ultrasound (IVUS) and optical coherence tomography (OCT). In this review, we will give a concise summary about the basic understanding and histological findings of neoatherosclerosis. We will focus on the description of in-vivo findings using IVUS and OCT, discussing advantages and pitfalls. Furthermore, recent developments regarding innovative molecular imaging techniques for a more precise and advanced examination of neoatherosclerotic plaques will be discussed.
