Cardiovascular disease encompasses coronary artery disease and valvular heart disease, and the prevalence of both increases with age. Over the past decade, the landscape of interventional cardiology has evolved to encompass a new set of percutaneous procedures outside the coronary tree, including transcatheter aortic valve implantation, transcatheter mitral valve repair, and left atrial appendage occlusion. These interventions have sparked a new discipline within interventional cardiology referred to as structural heart disease (SHD) intervention...

BACKGROUND: Aortic stenosis is a frequent disease in the elderly, and is associated with other systemic pathologies that may contraindicate the surgical procedure. Another option for these patients is percutaneous aortic valve implantation, which is less invasive. We present our initial experience with this procedure. MATERIAL AND METHODS: Patients with aortic stenosis were included once selection criteria were accomplished. Under general anaesthesia and echocardiographic and fluosocopic control, a transcatheter aortic valve was implanted following s valvuloplasty...

Valve-in-valve implantation of a transcatheter heart valve into a failed bioprosthetic heart valve has emerged as a treatment alternative to repeat conventional surgery. This requires careful pre-procedural assessment using non-invasive imaging to identify patients at risk for procedure related adverse events, such as ostial coronary occlusion. Herein we report how to comprehensively assess aortic root anatomy using computed tomography prior to transcatheter valve implantation for failed bioprosthetic aortic valves...

This paper discusses two male patients with severe aortic stenosis, whose right coronary arteries (RCA) were completely occluded during transcatheter aortic valve implantation (TAVI), leading to fatal hemodynamic disorder. Occlusions of RCA complicated by TAVI are rare. In addition, emergency cardiopulmonary bypass (CPB) played a critical role in rescuing our second patient. Both patients were admitted for "severe aortic stenosis," and TAVIs were performed. The first patient's blood pressure immediately dropped to 70/40 mmHg after the balloon expansion and did not increase much after the administration of aramine or fluid therapy...

A 92-year-old woman was admitted to a hospital with severe aortic valve stenosis for transcatheter aortic valve implantation (TAVI). TAVI was performed under general anaesthesia. After balloon valvuloplasty, the patient became hypotensive and transesophageal echocardiography showed severe aortic regurgitation with severely depressed left ventricular wall motion. A 26 mm Sapien XT valve was deployed. However, the ventricular wall motion was still severely depressed. Coronary angiography showed occlusion of the mid-left anterior descending (LAD) artery...

Transcatheter aortic valve implantation was introduced into clinical practice in 2002 as a rescue approach in patients presenting with symptomatic severe aortic stenosis but not eligible for conventional aortic valve replacement. This technique allows implantation of a balloon expandable bioprosthesis without resection of the native aortic valve. Several complications are described as a consequence of the residual highly calcified valve being squeezed against the aortic wall by the stent of the implant. This can result in deformation of the metal stent and paravalvular leakage, risk of occlusion of the coronary ostia, or central and peripheral embolization of valvular debris...

Transcatheter aortic valve replacement (TAVR) is an increasingly common procedure for the treatment of aortic stenosis in elderly patients with comorbidities that prevent the use of standard surgery. It has been shown that implantation without aortic regurgitation is related to lower mortality. Mild paravalvular regurgitation is inevitable in some cases due to calcification of the aortic annulus and its usually somewhat elliptical shape. Central regurgitation is less common, but has been associated with valve overdilatation in cases in which reduction of paravalvular regurgitation was attempted after the initial inflation...

OBJECTIVES: Management of degenerated aortic valve bioprosthesis classically requires redo surgery, but transcatheter aortic valve-in-valve implantation is becoming a valid alternative in selected cases. In the case of a degenerated Mitroflow bioprosthesis, TAVR is associated with an additional challenge due to a specific risk of coronary occlusion. We aimed to assess the safety and feasibility of transfemoral valve-in-valve implantation of the new Edwards Sapien 3 (Edwards Lifesciences) in a degenerated Mitroflow bioprosthesis (Sorin Group, Inc)...

An 81-year-old man with high-grade aortic valve stenosis and status post-coronary artery bypass grafting and supracoronary replacement of the ascending aorta was referred for transcatheter aortic valve implantation. He was in New York Heart Association class III and had dyspnea. After appropriate screening, we implanted a 29-mm SAPIEN XT valve (Edwards Lifesciences, Irvine, CA USA) through a transapical approach because of severe peripheral arterial occlusive disease. Postinterventional aortography revealed correct positioning and function of the valve and free coronary ostia but contrast extravasation in the vicinity of the interposed vascular prosthesis, resulting in severe luminal narrowing...

A case is presented of the early degeneration of a 21 mm SOLO stentless valve concomitant with severe mitral regurgitation (MR). Transcatheter valve-in-valve implantation was considered in this high-risk case (logistic EuroSCORE 29.3%), but was dismissed because of the risk of coronary occlusion, an absence of visual landmarks, and the impossibility to treat the MR. Following the implantation of a 27 mm Medtronic Hancock II mitral bioprosthesis, the leaflets of the SOLO valve were removed, and a 19 mm 3f Enable sutureless bioprosthesis delivered into the remaining sewing belt of the stentless valve...

AIMS: Transcatheter aortic valve-in-valve implantation is an emerging alternative to conventional surgical aortic valve replacement (SAVR) in patients with degenerated aortic bioprostheses. This procedure presents a high risk of coronary occlusion, especially during treatment of patients implanted with a bioprosthesis with a lower distance between the leaflets and the coronary ostia, such as the Mitroflow valve (Sorin S.p.A., Milan, Italy). In this report we aim to describe the safety and feasibility of transfemoral valve-in-valve implantation of a new-generation Lotus™ Aortic Valve Replacement System (Boston Scientific, Marlborough, MA, USA) in a case of degenerated Mitroflow bioprostheses...

Blood cysts of the heart are benign cardiovascular tumors found incidentally in approximately 50% of infants who undergo autopsy at less than 2 months of age. These congenital cysts, frequently present on the atrioventricular valves of infants, are exceedingly rare in adults. Nonetheless, in adults, cardiac blood cysts have been found on the mitral valve, papillary muscles, right atrium, right ventricle, left ventricle, and aortic, pulmonic, and tricuspid valves. Reported complications include left ventricular outflow obstruction, occlusion of the coronary arteries, valvular stenosis or regurgitation, and embolic stroke...

Coronary occlusion is a life-threatening complication during transcatheter aortic valve implantation (TAVI) that requires immediate revascularization. Conventionally, a total of 3 catheters are required to protect the coronary ostia during TAVI: a pigtail catheter for the angiographic evaluation of valve positioning, a guiding catheter, and a TAVI delivery system. In this case series, we present a new, simplified technique for patients who require coronary protection during TAVI using a total of only 2 catheters: a guiding catheter and TAVI delivery system...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has been developed recently for patients with high morbidities and who are believed to be not tolerate standard surgical aortic valve replacement. Nevertheless, the TAVI is associated with complications such as potential obstruction of coronary ostia, mitral valve insufficiency, and stent migration although it seems promising. Impairment of the coronary blood flow after TAVI is catastrophic and it was believed to be associated with the close position of the coronary orifice and the aortic leaflets and valve stent...
