A 72-year-old female with a previous history of aortic valve replacement by biological prosthesis was admitted with progressive heart failure. The clinical course was unfavorable, requiring inotropic support and invasive mechanical ventilation. Auto-triggering of the ventilator from cardiac origin has been previously described, and explained as a consequence of hyperdynamic circulation. In our case, the oscillatory movements due to the aortic regurgitation are transmitted to the airway. Early recognition of this condition can facilitate not only the correction this asynchrony in mechanical ventilation but also should raise the suspicion of aortic regurgitation...

A small-sized bioprosthesis can limit transcatheter valve-in-valve (V-in-V) implantations. The case is reported of a 91-year-old woman who had successfully undergone a V-in-V procedure with a 26 mm CoreValve in a previously implanted Mitroflow 19 mm valve. At the five-year follow up the prosthesis showed good echocardiographic function and the patient was alive and free from major symptoms. The patient died three months after the follow up examination at the age of 96 years. This case demonstrates the feasibility, with acceptable longterm functioning, of a V-in-V procedure involving a small bioprosthesis...

Transcatheter valve-in-valve (VIV) implantation has been recently proposed as an alternative to surgical reoperative aortic valve replacement in patients with a failing aortic bioprosthesis. Experience with transcatheter VIV implantation at other valve positions is very limited. Herein is reported the case of an 18-year-old man with Ebstein's anomaly and severe tricuspid valve (TV) regurgitation status after bioprosthetic valve replacement, who developed new dyspnea on exertion three years after the initial valve replacement...

The case is reported of a 79-year-old female who received a patch augmentation of the tricuspid anterior and septal leaflets with a resected left atrial wall to address recurrent tricuspid regurgitation, including tricuspid valve tethering. The patient was admitted to the authors' hospital for chronic heart failure with paravalvular leakage after aortic valve replacement and recurrent severe tricuspid regurgitation. She had undergone two previous cardiac surgeries. Re-tricuspid repair required an augmentation of the tricuspid valve leaflets in addition to tricuspid annuloplasty...

Granulomatosis with polyangiitis (GPA) is a rare vasculitis that can have multisystem involvement, though cardiac involvement is very rare. The case is described of a 53-year-old woman who presented with acute aortic and mitral valve regurgitation requiring surgical intervention. Pathology from the excised aortic valve showed geographic necrosis concerning for GPA. Subsequent rheumatologic testing was positive for anti-serine proteinase 3 (PR3) antibody, consistent with GPA. A year after the valve surgery the patient was found to have a vegetation of the mitral valve and elevated PR3 antibody levels, and was successfully treated with an intensification of immunosuppression...

BACKGROUND AND AIM OF STUDY: One of the first steps in qualifying a new prosthetic valve for eventual clinical use is preclinical flow performance testing in vitro. Such testing is typically performed in an in-vitro test system that simulates the pumping mechanics of the left ventricle of the heart, generally referred to as a pulse duplicator or duplicator. Historically, test results in these systems have varied from duplicator to duplicator. This collaborative effort between heart valve manufacturers and the Food and Drug Administration (FDA) was designed to evaluate the variability of the pulse duplicator test technology for pulsatile flow performance measurement in an interlaboratory round robin...

BACKGROUND: The study aim was to analyze the authors' experience with aortic root surgery in Marfan syndrome (MFS), and to expand the surgical outcome data of patients meeting the Ghent criteria (Marfan registry). METHODS: Analyses were performed of data acquired from MFS patients (who met the Ghent criteria), including an aortic root surgery and Kaplan-Meier survival. RESULTS: Between April 2004 and February 2012, a total of 59 MFS patients (mean age at surgery 36 ± 13 years) underwent 67 operations for aortic root aneurysm (n = 52), aortic valve (AV) regurgitation (n = 15), acute aortic dissection (n = 2), and/or mitral valve (MV) regurgitation resulting from MV prolapse (n = 7)...

BACKGROUND: Left ventricular (LV) function and the dimensions of aortic valves from normally functioning bicuspid aortic valve (BAV) patients were compared with those of healthy control patients. A comparison between patients with antero-posterior BAV (BAV-AP) or right-left BAV (BAV-RL) was also performed, and the determinants of aortopathy and LV function were investigated. METHODS: Sixty-eight patients with aortic velocities <2 m/s and trivial or mild aortic regurgitation were included in the study...

Aortic regurgitation (AR) is characterized by the backflow of blood from the aorta to the left ventricle. Acute AR typically causes severe pulmonary edema and hypotension, and is a surgical emergency. In chronic AR, however, compensatory mechanisms can clinically compensate for years, with normal left ventricular function and no symptoms. While the hemodynamic mechanisms of chronic AR on the left ventricle are well described, the hemodynamic mechanisms of acute AR are not clear. Most of the literature on acute AR includes either small series or case reports...

Aortic regurgitation (AR) after transcatheter aortic valve replacement (TAVR) is associated with an increased risk of mortality. In severe cases, abrupt hemodynamic changes may occur with a sudden increase in left ventricular end-diastolic pressure that results in frank pulmonary edema, hypoxia, and cardiogenic shock. Here, the case is reported of a patient who developed severe AR immediately after valve deployment that led to severe hemodynamic compromise. The procedural techniques necessary for the immediate management of severe transvalvular and paravalvular AR are described...

We are presenting a case report of failed valve-in-valve treatment of severe aortic stenosis. A control ultrasonography after TAVI implantation revealed a severe aortic regurgitation of the graft which was subsequently unresolved with postimplantation dilatation. Second TAVI was implanted with cranial dislocation to the aortic root. Patient underwent a CT examination to clarify the TAVI in TAVI position. Patient underwent a surgical resection of TAVI with implantation of biological aortic valve prosthesis. In situations where TAVI treatment fails or is complicated beyond the possibility of endovascular repair, surgical intervention despite its higher risks is the preferred choice...

Transcatheter aortic valve replacement (TAVR) has become a widely accepted therapeutic option for patients with severe, symptomatic aortic stenosis at intermediate, high, or extreme risk for conventional surgery as determined through a heart team approach. Two valve prostheses are currently available and the Food and Drug Administration (FDA) approved in the United States for TAVR: the self-expandable Medtronic CoreValve (Medtronic, Inc., Minneapolis, MN, USA) and the balloon-expandable Edwards Sapien Valve (Edwards Lifesciences, Irvine CA, USA)...

Mitral regurgitation (MR) is a common cause of morbidity worldwide and an accepted indication for interventional therapies which aim to reduce or resolve adverse clinical outcomes associated with MR. Cardiac magnetic resonance (CMR) provides highly accurate means of assessing MR, including a variety of approaches that can measure MR based on quantitative flow. Additionally, CMR is widely accepted as a reference standard for cardiac chamber quantification, enabling reliable detection of subtle changes in cardiac chamber size and function so as to guide decision-making regarding timing of mitral valve directed therapies...

Traumatic tricuspid regurgitation is a rare and progressive disease. Early diagnosis and surgical valve repair are very important. A 57-year-old male was referred to our hospital with a history of blunt chest trauma. Three-dimensional echocardiography showed severe tricuspid regurgitation and demonstrated two main anterior leaflet chordaes of the tricuspid valve rupture and the whole anterior leaflet prolapsed. The diagnosis was severe tricuspid regurgitation due to leaflet chordae rupture secondary to blunt chest trauma...

We describe a case of submitral aneurysm in a 40-year-old man, which was distinctive in its anatomy and pathophysiology. The patient had a congenital submitral aneurysm located in the anterolateral part of the mitral annulus, complicated by dissection of the left atrial wall, severe mitral regurgitation, and compression of the left circumflex artery. He was managed successfully with aid of a comprehensive preoperative evaluation with all available imaging guidance and methodical surgical techniques, resulting in exclusion of the aneurysm, mitral valve replacement, and a graft to the left circumflex artery...

Transcatheter aortic valve implantation (TAVI) is recommended for patients who are inoperable or at high risk for surgical aortic valve replacement (SAVR). Corticosteroid therapy is considered to be a risk factor for SAVR, but there is a paucity of information about TAVI in patients taking corticosteroids. The aim of this study is to elucidate the outcome of TAVI in patients on chronic corticosteroid therapy, compared with SAVR. We retrospectively analyzed patients on corticosteroid therapy who underwent TAVI (n = 21) or SAVR (n = 30) for severe aortic stenosis in Sakakibara Heart Institute...

Ischaemic papillary muscle rupture causing acute severe mitral regurgitation (MR) has a dramatic presentation and a very high mortality. Emergent surgical repair improves outcomes, which necessitates robust preoperative stabilisation. Here we discuss a patient with cardiogenic shock with an acute severe MR that was deemed very high risk for emergent valve replacement due to haemodynamic instability and respiratory failure. A percutaneous left ventricular assist device Impella 2.5 (Abiomed, Danvers, MA) drastically improved clinical status, and the patient underwent a successful surgical mitral valve replacement soon after placement of the temporary assist device...

BACKGROUND: Arterial hypertension is the commonest cause of cardiovascular death. It may lead to hypertensive heart disease (HHD), including heart failure (HF), ischemic heart disease (IHD) and left ventricular hypertrophy (LVH). MAIN BODY: According to the 2007 ESH/ESC guidelines, the recommended imaging technique is echocardiography (echo), when a more sensitive detection of LVH than that provided by ECG, is needed. Cardiovascular Magnetic Resonance (CMR), a non-invasive, non-radiating technique, offers the following advantages, beyond echo: a) more reliable and reproducible measurements of cardiac parameters such as volumes, ejection fraction and cardiac mass b) more accurate differentiation of LVH etiology by providing information about tissue characterisation c) more accurate evaluation of myocardial ischemia, specifically if small vessels disease is present d) technique of choice for diagnosis of renovascular, aortic tree/branches lesions and quantification of aortic valve regurgitation e) technique of choice for treatment evaluation in clinical trials...
