Prosthesis-patient Mismatch (PPM) is not uncommon with an incidence reported up to 70% after aortic valve (AV) replacement. Severe forms of PPM are less common (up to 20%); PPM can lead to increased short- and long-term morbidity and mortality. It is important to discriminate PPM from other forms of prosthetic valve dysfunction. Sometimes, prosthetic valve degenerative disease may coexist with PPM. Echocardiography plays an important role in the prevention and diagnosis of PPM. Preemptive strategies to prevent PPM include insertion of newer generation prosthetic valves with better hemodynamic characteristics, stentless prosthesis, aortic root enlargement to insert a larger prosthesis, aortic homograft, and transcutaneous AV implantation...

In the recent decade medicine developed far beyond people's mind, as transcutaneous aortic valve replacement(TAVR), Mitraclip et al. As recent development of information technology has changed to real time information system in the world, international communication in the field of cardiovascular surgery has also changed to become large in volume, rapid in time and frequent and convenient in use. The Asian Society for Cardiovascular and Thoracic Surgery(ASCVTS) which has a major role of international communication in the field cardiovascular surgery in Japan, has developed to become one of the major international academic society...

BACKGROUND: Postoperative serum troponin levels and perioperative myocardial infarction (MI) rates correlate with mortality and morbidity following cardiac surgery. The objective of this study was to document the release profile of high sensitivity troponin T (hsTnT) following different cardiac operations. METHODS: Patients undergoing one of five different isolated cardiac surgical procedures (eligible preoperative hsTnT <29ng/L, serum creatinine < 0.2mmol/L) were recruited prospectively...

BACKGROUND: Little is known about the valve degeneration process after transcutaneous aortic valve implantations (TAVI) that can have an important impact on patients' long-term prognosis. AIM: To evaluate degenerative changes of TAVI using computed tomography (CT) compared to findings in patients that underwent surgical aortic valve replacement (SAVR). Subsequently, to compare the level of immune and inflammatory markers in both groups and test their possible role in the valve degeneration process...

BACKGROUND: Aortic valve stenosis (AVS) can be complicated by bleeding associated with acquired type 2A von Willebrand syndrome. The association of AVS and gastrointestinal bleeding from angiodysplasia is defined as Heyde syndrome. We sought to evaluate the effect of transcutaneous aortic valve implantation (TAVI) on hemostasis disorders and to assess its effectiveness to treat Heyde syndrome. METHODS: We prospectively enrolled 49 consecutive patients with severe AVS addressed for TAVI at our institution...

Transcatheter aortic valve implantation (TAVI) is a relatively novel procedure first performed in 2002 and has undergone rapid development since then. Its main indication is treatment of severe symptomatic aortic valve stenosis. Initially, the procedure was indicated for very sick patients who were not eligible for surgical aortic valve replacement. However, rapid development of the technology and operator skill required for TAVI allowed widening of the indications for its use. Currently, there is evidence that TAVI could be better than the surgical intervention in a broad population and not only in the most sick...

The association between aortic valve stenosis and gastrointestinal bleeding, traditionally known as Heyde's syndrome, is the result of a quantitative loss of the highest molecular weight von Willebrand multimers (type 2A von Willebrand syndrome). This results in bleeding from areas of high shear stress such as gastrointestinal angiodysplasias. Correction of this bleeding diathesis after surgical aortic valve replacement has been well described. The effect of transcutaneous aortic valve implantation on Heyde's syndrome has yet to be studied...

Aortic stenosis is a valve disorder that includes not only valve narrowing but also changes in the left ventricle and intracardiac hemodynamics. Older patients with aortic stenosis often have co-existing pathologic disorders, which influence the pathophysiology, symptom expression and prognosis. There is also increasing awareness that severe aortic stenosis could be associated with low transvalvular pressure gradient caused by a variety of mechanisms. Surgical and transcutaneous valve replacements are currently available interventions for patients with severe aortic stenosis...

OBJECTIVES: The German Aortic Valve Registry (GARY) seeks to provide information on a real-world, all-comers basis for patients undergoing aortic valve interventions. This registry comprises patients undergoing the complete spectrum of transcutaneous and conventional surgical aortic valve interventions. The aim of this study was to use the GARY registry to evaluate conventional and catheter-based aortic valve interventions in several risk groups. METHODS: A total of 13 860 consecutive patients undergoing intervention for aortic valve disease [conventional aortic valve replacement (AVR) or transvascular/transapical TAVR (TV-/TA-TAVR)] were enrolled in 78 German centres in 2011...

Despite the higher incidence of paravalvular regurgitation (PVR) with transcatheter aortic valve replacement (TAVR), this novel treatment modality has rapidly emerged as a reasonable alternative to surgical aortic valve replacement (SAVR) in high risk and inoperable patients. This review will discuss the current literature with respect to assessment, outcomes, predictors, and intraprocedural treatment options of PVR following TAVR. Understanding the predictors may help reduce the incidence of PVR and improving the outcome of this procedure...

OBJECTIVE: To assess the feasibility of transcatheter aortic valve implantation (TAVI; Medtronic CoreValve and Edwards SAPIEN XT) under local anaesthesia with only mild analgesic medication and fluoroscopic guidance. METHODS: 461 patients underwent TAVI under local anaesthesia with lidocaine. The procedure was performed successfully in 459 of the cases. All patients were also treated with piritramide, metoclopramide hydrochloride and 62 mg dimenhydrinate. Monitoring consisted of a six-electrode, virtual 12-lead ECG, pulse oximetry, and invasive arterial pressure measurement...

The development of rapid deployment and sutureless aortic valves represents a translation of knowledge gained from the performance of transcutaneous aortic valve replacement (AVR) procedures combined with decades of experience of conventional AVR surgery. Such devices have gained increasing clinical acceptance-particularly in Europe-with almost 3000 total implants to date. Rapid deployment and sutureless valves facilitate minimal invasive AVR and are associated with significantly reduced myocardial ischaemic and cardiopulmonary bypass times...

IMPORTANCE: Aortic stenosis is the most common form of valvular heart disease. Progression of aortic stenosis is very slow and highly variable. Decisions about when to perform valve surgery are made by subjective assessment of patient symptoms and objective measures of the valve and ventricular function by transthoracic echocardiography. OBJECTIVE: To review current concepts regarding the development, progression, and assessment of aortic stenosis; the appropriate monitoring intervals for transthoracic echocardiography; and the indications for valve procedures...

IMPORTANCE: The US Food and Drug Administration recently approved the use of a transcatheter aortic valve in patients for whom traditional valve replacement surgery poses a high or prohibitive risk. Our hospital was one of the first Veterans Affairs facilities to launch a transcatheter aortic valve replacement (TAVR) program. OBJECTIVE: To evaluate our early experience with transfemoral TAVR. DESIGN AND SETTING: We retrospectively reviewed the records of all patients who underwent TAVR during the first year of our program at the Department of Cardiothoracic Surgery, Michael E...

OBJECTIVES: We aimed to compare the performance and midterm survival of transcutaneous aortic valve replacement (TAVR) and surgically implanted stentless aortic valve replacement (SAVR) for severe aortic stenosis in patients anticipated to have patient-prosthesis mismatch (PPM). METHODS: A retrospective analysis was performed of 86 and 49 consecutive TAVR and SAVR patients with severe aortic stenosis and calculated minimal effective orifice area larger than the best projected effective orifice area...
