The transcatheter aortic valve implantation (TAVI) consist an alternative treatment in patients with severe aortic stenosis. Multimodality imaging using transthoracic echocardiography (TTE) or transesophageal echocardiography (TOE) and multislice CT (MSCT) constitute cornerstone techniques for the pre-operative management, peri-procedural guidance, follow up and recognition of possible transcatheter valve related complications. CT angiography is much more accurate regarding the total definition of aortic annulus diameter and circumferential area...

BACKGROUND: Infective endocarditis (IE) is still a condition with high mortality and morbidity, especially in the elderly, and in patients with prosthetic valves. The concept of "time-to-therapy" plays a key role for the prompt management of IE and related complications, and the currently available multimodality imaging may play a key role in this setting. Myocardial ischemia due to extrinsic coronary compression from an aortic abscess is an extremely rare condition where the optimal therapeutic strategy has not been defined yet...

BACKGROUND: Right ventricular (RV) systolic dysfunction is associated with worse survival in patients undergoing surgical aortic valve replacement (SAVR), yet it is not included in traditional risk scores of transcatheter aortic valve implantation (TAVI) candidates. We aimed to evaluate the prognostic value of RV systolic function on clinical outcomes in patients undergoing TAVI at one year follow-up; and, echocardiographic changes of RV systolic function up to 12 months after TAVI and compared with SAVR when possible...

Aims: A 3D transoesophageal echocardiography (3D-TOE) reconstruction tool has recently been introduced. The system automatically configures a geometric model of the aortic root and performs quantitative analysis of these structures. We compared the measurements of the aortic annulus (AA) obtained by semi-automated 3D-TOE quantitative software and manual analysis vs. multislice computed tomography (MSCT) ones. Methods and results: One hundred and seventy-five patients (mean age 81...

Transcatheter aortic valve replacement (TAVR) has become the preferred therapy for treatment of severe aortic stenosis in patients at intermediate to high risk of perioperative mortality following surgical aortic valve replacement. Haemodynamic assessment is an integral part of the procedure, and it is crucial for the operator to have an in-depth understanding of the haemodynamic alterations that occur during balloon aortic valvuloplasty and transcatheter valve deployment. Comprehension of the haemodynamic tracings is also pivotal for early recognition of periprocedural complications...

Trancatheter heart valve (THV) thrombosis is effectively treated with anticoagulation but alternative therapies are required when a faster gradient reduction is needed. Open heart surgery has been rarely performed due to the high perioperative mortality and only five cases have been described so far. Here we describe a case of emergent surgical explantation for THV thrombosis after a valve-in-valve. A 67years old man underwent transcatheter aortic valve implantation for a failed surgical bioprosthesis Epic 21mm (St...

The development of an aorto-right ventricular fistula is a rare complication of cardiac surgery. The most common treatment is surgical closure of the fistula, but percutaneous closure of the fistula has become an attractive alternative option. We present a case of successful utilization of live/real time three/four-dimensional transoesophageal echocardiography (3/4DTEE) to select the correct device size for percutaneous closure of an adult patient presenting with an aorto-right ventricular (AO-RV) fistula following aortic valve replacement...

Bicuspid aortic valve is the most common congenital cardiac defect in adults, and symptom typically develops in adulthood. In the majority of cases, bicuspid aortic valve disease progress with ages and surgical aortic valve replacement is performed with excellent operative outcomes. However, with the relatively slow progression of disease, surgical aortic valve replacement is required in elderly patients but the surgical risk often deemed extremely high due to old age and multiple comorbidities. Transcatheter aortic valve replacement (TAVR) has evolved from a novel technology to an established therapy for intermediate- and high-risk patients with symptomatic severe aortic valve stenosis (AS)...

Endoscopic procedures, such as transesophageal echocardiography, gastroscopy, and airway fibroscopy, routinely are performed in a heterogenous population of patients for diagnostic/interventional purposes (eg, transfemoral aortic valve replacement, airway fibroscopies, and intubation). Sedation frequently is administered to achieve an appropriate degree of patient compliance and procedure success. Patients with reduced respiratory reserve or those who are overly sedated, however, may develop hypoxia and respiratory failure during endoscopies, necessitating premature termination of the examination itself...

The use of transcatheter aortic valve replacement (TAVR) has risen dramatically during the past decade. Notably, the procedure can reduce symptoms and improve prognosis in patients who would otherwise be excluded from intervention due to prohibitive surgical risk. During the same time period, the use of percutaneous mechanical circulatory support devices for patients with severe left ventricular dysfunction, including the Impella System (Abiomed, Inc., Danvers, MA, USA), has also increased. These devices provide superior hemodynamic effects compared to intra-aortic balloon pumping...

Degenerative aortic valve stenosis is the most common valvular heart disease seen in developed countries. Since the implementation of transcatheter aortic valve replacement, there has been a surge of efforts to improve procedural technique as well as reduce mortality. Until recently, the mainstay method of assessment of valve implantation as well as paravalvular regurgitation has relied heavily on imaging techniques including transesophageal echocardiography and aortic root angiography. There has been a lot of scientific inquiry to identify biomarkers in the management of patients with aortic stenosis...

BACKGROUND:  Transcatheter aortic valve implantation (TAVI) has evolved into an alternative procedure to surgical valve replacement for high-risk patients with aortic valve stenosis. Despite technical innovations, there is still a risk of complications during and after the intervention. After a TAVI procedure, ECG-gated multidetector computed tomography (MDCT) plays an important role in the early diagnosis of local complications. In this article, we explain for the first time how the technical acquisition of MDCT in the region of the aortic root is performed as post-interventional control of the TAVI prosthesis...
