An 89-year-old woman appeared to have acute coronary syndrome at the left main trunk (LMT) complicated with severe aortic stenosis, moderate-severe mitral regurgitation, depressed left ventricular (LV) function, and multivessel disease. Because of sustained hypotension even under intra-aortic balloon pumping support during emergency coronary angiograhy, we performed primary percutaneous coronary intervention solely for the LMT lesion using a bare metal stent, leading to recovery from the shock state. On the second hospital day, based on our heart-team consensus, we performed aortic valve replacement and coronary artery bypass grafting surgery, and added edge-to-edge repair (Alfieri stitch) of the mitral valve, resulting in complete revascularization and dramatically improved LV function...

BACKGROUND: Computed tomography angiography (CTA) is the test of choice for pre-procedure imaging of transcatheter aortic valve replacement (TAVR) candidates. The iodinated contrast required, however, increases the risk of renal dysfunction in patients with pre-existing renal failure. Ferumoxytol is a magnetic resonance imaging (MRI) contrast agent that can be used with renal failure. Its long vascular resonance time allows gated MRA sequences that approach CTA in image quality. We present respiratory and cardiac gated MRA enabled by ferumoxytol that can be post-processed in an analogous fashion to CTA...

BACKGROUND: Stress echocardiography (SE) has an established role in evidence-based guidelines, but recently its breadth and variety of applications have extended well beyond coronary artery disease (CAD). We lack a prospective research study of SE applications, in and beyond CAD, also considering a variety of signs in addition to regional wall motion abnormalities. METHODS: In a prospective, multicenter, international, observational study design, > 100 certified high-volume SE labs (initially from Italy, Brazil, Hungary, and Serbia) will be networked with an organized system of clinical, laboratory and imaging data collection at the time of physical or pharmacological SE, with structured follow-up information...

Quadricuspid aortic valve is an extremely rare congenital heart anomaly that often causes valve incompetence, requiring surgical intervention. Care must be taken to avoid surgical complications in patients with quadricuspid aortic valve; thus, preoperative diagnosis is important. A 76-year-old man presented with exertional dyspnea due to aortic regurgitation. Transthoracic and transesophageal echocardiography revealed severe aortic regurgitation caused by quadricuspid aortic valve. To avoid interference with the cardiac conduction system, we performed aortic valve replacement using an ingenious technique, in which pledgeted sutures on the accessory leaflet were placed from outside the sinus of Valsalva to above the aortic annulus...

A 57-year-old male with ascending aortic aneurysm, severe aortic regurgitation, and severe mitral regurgitation (MR) underwent ascending aortic replacement and aortic valve replacement. MR in this patient with normal mitral valve morphology was considered secondary to aortic valve incompetency. Consequently, a surgical approach to restore aortic valve function was adopted with successful MR resolution. This case report demonstrates the possibility of reversing early functional mitral regurgitation without surgically approaching the mitral valve...

An incompetent aortic valve (AV) results in aortic regurgitation (AR), where retrograde flow of blood into the left ventricle (LV) is observed. In this work, we parametrically characterized the detailed changes in intra-ventricular flow during diastole as a result of AR in a physiological in vitro left-heart simulator (LHS). The loss of energy within the LV as the level of AR increased was also assessed. The validated LHS consisted of an optically-clear, flexible wall LV and a modular AV holder. Two-component, planar, digital particle image velocimetry was used to visualize and quantify intra-ventricular flow...

AIMS: Quantitative mitral regurgitation (MR) grading remains challenging. This study evaluated the concept of integrating echocardiography and computed tomography for grading MR severity. Specifically, an integrated parameter was developed that combines the true cross-sectional mitral regurgitant orifice area (ROA) assessed with multi-detector row computed tomography (MDCT) with flow data from echocardiography. METHODS AND RESULTS: Systolic MDCT data of 73 patients, referred for transcatheter aortic valve implantation (TAVI) who also had MR, were evaluated...

Quadricuspid aortic valve (QAV) is a rare congenital heart disease. The functional status of QAV is predominantly a pure aortic regurgitation. Clinical manifestations of patients with a QAV depend on the functional status of the QAV and the associated disorders. Significant valvular regurgitation and (or) stenosis is often present with subsequent operation performed at the fifth to sixth decade of life. The functional status of QAV is predominantly regurgitant; whereas pure stenotic QAV can be as few as in only 0...

AIMS: Myxomatous valve disease (MVD) is the most common aetiology of primary mitral regurgitation. Recent studies suggest that defects in heart valve development can lead to heart valve disease in adults. Wnt/β-catenin signalling is active during heart valve development and has been reported in human MVD. The consequences of increased Wnt/β-catenin signalling due to Axin2 deficiency in postnatal valve remodelling and pathogenesis of MVD were determined. METHODS AND RESULTS: To investigate the role of Wnt/β-catenin signalling, we analysed heart valves from mice deficient in Axin2 (KO), a negative regulator of Wnt/β-catenin signalling...

BACKGROUND: With improving technologies and an increasingly elderly populations, there have been an increasing number of therapeutic options available for patients requiring aortic valve replacement. Recent evidence suggests that transcatheter aortic valve implantation (TAVI) is one suitable option for high risk inoperable patients, as well as high risk operable patients. Sutureless valve technology has also been developed concurrently, with facilitates surgical aortic valve replacement (SUAVR) by allow resection and replacement of the native aortic valve with minimal sutures and prosthesis anchoring required...

BACKGROUND: The role of speckle-tracking echocardiography in the assessment of chronic aortic regurgitation (AR) is not established. Load dependency may encumber the interpretation of strain measurements in the chronically overloaded left ventricle. The aim of this study was to investigate the mechanisms of left ventricular (LV) contraction patterns in asymptomatic patients with moderate to severe AR and preserved ejection fractions. METHODS: In this prospective, cross-sectional study, 31 patients with moderate to severe AR, 15 elite endurance athletes, and 17 healthy control subjects were examined using three-dimensional speckle-tracking echocardiography...
