BACKGROUND: Minimally invasive aortic valve replacement (MIAVR) through a mini-thoracotomy is comparable to AVR through a sternotomy, but may have increased surgical times. The development of adjuncts such as the automatic knot fastener and percutaneous coronary sinus (CS) catheter may reduce this disadvantage. METHODS: A retrospective review conducted between 2002 and 2015 at a single institution revealed 78 patients who underwent MIAVR with adjuncts. The automatic knot fastener was used on all patients, and a successful CS catheter was placed and confirmed by echocardiography in 67 patients (86%)...

BACKGROUND: Post-implantation paravalvular leak (PVL) remains a significant complication of transcatheter aortic valve implantation (TAVI). More importantly, its occurrence may impact long-term mortality. AIM: We sought to evaluate the effects of balloon post-dilatation (PD) on the reduction of PVL and mortality in patients undergoing TAVI. METHODS: A total of 101 consecutive patients undergoing TAVI were enrolled. Angiography, echocardiography, and the aortic regurgitation index (ARI) were used to assess the severity of PVL before and after balloon PD...

Valve thrombosis can occur in mechanical prosthetic valves and is increasingly recognised in transcatheter and surgically implanted bioprosthetic valves. The risk of thrombosis of mechanical valves is higher in the mitral position compared with aortic position and in older generation valves (ball and cage valves). There is a wide spectrum of presentation from the asymptomatic patient to those with embolic complications or cardiogenic shock. A combination of transthoracic and transesophageal echocardiography is required to assess the haemodynamic effect of thrombosis (valve gradients and area), leaflet motion and thrombus size...

Satoshi Nakatani
Although clinically significant valve thrombosis after transcatheter aortic valve implantation (TAVI) is rare, the incidence of subclinical leaflet thrombosis has been reported to be up to about 10%-15%. It is mostly found 1-3 months after procedure in any type of transcatheter heart valve. Leaflet thrombosis is detected by high-resolution CT in the form of limited valve opening/closure and hypoattenuated leaflet thickening. Transthoracic or transesophageal echocardiography is capable of detecting limitations of valve motion, leaflet thickening, increased flow velocity across the valve...

OBJECTIVES: To investigate the feasibility, procedural success, and outcomes of paravalvular leak (PVL) closure in patients with prior transcatheter aortic valve replacement (TAVR). BACKGROUND: PVL after TAVR is associated with adverse patient outcomes and increased mortality. Percutaneous PVL closure has emerged as a therapeutic strategy for addressing this issue, but data for transcatheter PVL repair after TAVR remains limited. METHODS: This is a single center retrospective review of PVL closure after TAVR...

BACKGROUND: The use of transcatheter aortic valve replacement (TAVR) is increasing worldwide. We present our 6-year experience using three-dimensional (3D) transesophageal echocardiography (TEE) and investigate whether different sizing methods of the aortic annulus lead to different prosthesis size that may impact outcome. METHODS: We investigated 262 patients who underwent TAVR and had 3D TEE data sets of the aortic annulus. We have used the area-derived diameter (Darea = 2(area/π)) and the circumference-derived diameter (Dcirc = Circumference/π) to size the prosthesis in separate populations in different time periods...

BACKGROUND: The role of three-dimensional transesophageal echocardiography (3DTEE) vs multidetector computed tomography (MDCT) in aortic annular sizing has been poorly defined in patients undergoing transcatheter aortic valve replacements (TAVR). We set to determine the correlation between 3DTEE and MDCT in measuring the aortic annulus prior to TAVR. METHODS: In an observational, retrospective study, we compared aortic annular areas measured by MDCT and 3DTEE in TAVR patients...

Percutaneous valve-in-valve therapy is a life-saving procedure for patients at high risk of reoperation due to dysfunctional bioprosthetic valves. We have reviewed 3 typical cases of a valve-in-valve procedure using high-quality images to demonstrate the suitability of this method for aortic, mitral, and tricuspid positions. Three-dimensional transesophageal echocardiography combined with other modalities such as computerized tomography and fluoroscopy are key elements for anesthesia and procedural guidance, especially as immediate tools to assess valvular function and specific procedure-related complications...

AIMS: In the minimalist transcatheter aortic valve implantation (TAVI) era, the usage of transesophageal echocardiography becomes restricted. Conversely, aortography gains clinical ground in quantifying prosthetic valve regurgitation (PVR) during the procedure. In a mock circulation system, we sought to compare the contrast volume required and the accuracy of aortographic videodensitometric PVR assessment using a synchronized diastolic and standard (non-synchronized) injection aortography...

A 73-year-old male was brought into hospital with chest pain and inferior ST elevation on ECG. The patient immediately proceeded to the catheter lab for primary percutaneous coronary intervention. Angiography did not identify any culprit lesions to account for the patient's electrocardiographic changes and ongoing symptoms of chest pain. Bedside echocardiography revealed critical aortic stenosis. Intra-aortic balloon pump (IABP) was inserted, resulting in resolution of chest pain and ST-segment changes. The patient underwent successful aortic valve (AV) replacement without the need for coronary intervention...

Patients with valvular heart disease (VHD) should be treated for diabetes, hypertension, and hyperlipidemia. They also should receive therapy for left ventricular dysfunction, undergo interval echocardiography, and participate in aerobic exercise. Valve replacement should be considered for patients with aortic stenosis (AS) and syncope, presyncope, heart failure, angina, or severe AS with left ventricular dysfunction. Valve replacement is performed with open or transcatheter procedures; the latter are preferred for patients with high surgical risk...

BACKGROUND: Left atrial (LA) size is a marker of prognosis in severe aortic stenosis (AS). The aims of this retrospective study were to assess the impact of transcatheter aortic valve implantation (TAVI) on the recovery of LA phasic function and to assess the relationship between LA function and new-onset atrial fibrillation (NAF) after TAVI. METHODS: In this retrospective cohort study, LA function was measured using biplane volumes and 2-dimensional (2D) speckle tracking echocardiography (STE) in 52 patients (median age, 81 years) with severe AS before TAVI and at midterm follow-up...

The complementary modalities of Doppler echocardiography and multidetector computed tomography are most frequently used for the planning and follow-up of transcatheter aortic valve replacement (TAVR). TAVR is now a well-established modality in the treatment of high-risk and inoperable patients with symptomatic severe aortic stenosis. Furthermore, recent studies have shown that TAVR is equivalent or superior to surgical aortic valve replacement in patients at intermediate surgical risk. We review the most commonly used imaging modalities and discuss their respective strengths and contributions to optimal patient selection, procedure planning, implementation, and follow-up in TAVR...
