ECHOCARDIOGRAPHIC ASSESSMENT OF 537 DOGS WITH MITRAL VALVE PROLAPSE AND LEAFLET INVOLVEMENT
2009
In this work we investigated which mitral valve leaflet was most often involved in mitral valve prolapse with degenerative mitral valve disease and whether there was an association with breed, age, gender, or weight. Five hundred and thirty-seven dogs with mitral valve prolapse-degenerative mitral valve disease were assessed; the cross-breed dog was the most represented breed (248 dogs, 46.2%). Mitral valve prolapse was more common in male dogs, and the average age was 11.3 +/- 2.8 years. Prolapse of the anterior leaflet was present in 48.4% of dogs, prolapse of the the posterior leaflet in 7.1%, and bileaflet prolapse was present in 44.5%; this distribution is different than that typically…
Perforated giant mycotic aneurysm of mitral valve in a drug-addicted young man: Rare complication of infective endocarditis
2017
Infective endocarditis (IE) affects patients at high clinical risk and may present as an acute and rapidly progressive, subacute or chronic infection. Transthoracic and transesophageal echocardiography represent the key diagnostic method in IE diagnosis. In particular, three-dimensional transesophageal echocardiography represents the imaging technique that allows to establish with adequate accuracy dimensions, shape, and localization of endocarditis vegetations. In our case, we show a huge vermiform mycotic aneurysm in an immunodeficient young drug-addicted man with severe mitral valve regurgitation and the additive value of three-dimensional transesophageal echocardiography in this specifi…
Tricuspid Regurgitation and Mortality Risk Across Left Ventricular Systolic Function in Acute Heart Failure.
2015
BACKGROUND Tricuspid regurgitation (TR) is a common echocardiographic finding that has been related to adverse outcome under various clinical scenarios. Nevertheless, evidence supporting its prognostic value in heart failure (HF) is scarce, and, in most cases, contradictory. We evaluated the association of TR grade with 1-year all-cause mortality in acute HF (AHF). METHODS AND RESULTS: We included 1,842 consecutive patients admitted for AHF. Mean age was 72.8±11.3 years, 51% were female and 45.5% had LVEF <50%. The severity of TR was graded in non-TR, mild (1), moderate (2), moderate-severe (3) and severe (4). At 1-year follow-up, 370 patients (20.1%) had died. In patients with LVEF ≥50%, a…
Sex-Related Clinical Characteristics and Outcomes of Patients Undergoing Transcatheter Edge-to-Edge Repair for Secondary Mitral Regurgitation.
2021
OBJECTIVES The authors sought to assess sex-based differences in characteristics and outcomes of patients undergoing transcatheter edge-to-edge mitral valve repair (TMVR) for secondary mitral regurgitation (SMR). BACKGROUND Subgroup analysis from the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart��Failure Patients with Functional Mitral Regurgitation) trial indicated potential sex-related differences in outcomes after TMVR. The impact of sex on results after TMVR in a real-world setting is unknown. METHODS The authors assessed clinical outcomes and echocardiographic parameters in women and men undergoing TMVR for SMR between 2008 and 2018 who were …
Prognostic value of the ratio between prothesis area and indexed annulus area measured by multiSlice-CT for transcatheter aortic valve implantation p…
2016
Background Postprocedural aortic regurgitations following transcatheter aortic valve implantation (TAVI) procedures remain an is- sue. Benefit of oversizing strategies to prevent them isn’t well established. We compared different level of oversizing in our cohort of con- secutive patients to address if severe oversizing compared to normal sizing had an impact on post-procedural outcomes. Methods From January 2010 to August 2013, consecutive patients were referred for TAVI with preoperative Multislice-CT (MSCT) and the procedures were achieved using Edwards Sapien® or Corevalve devices®. Retrospectively, according to pre-procedural MSCT and the valve size, pa- tients were classified into thr…
Über eine bakterielle Vorverdauung und eine proteolytische Hauptverdauung im Darm der Nashornkäferlarve (Oryctes nas. L.)
1955
The larva ofOryctes nas. L. shows a bacterial predigestion in the rectal-saccus. The main breakdown of proteins takes place in the middle gut, closely connected with the act of regurgitation.
Improved Assessment of Pathological Regurgitation in Patients with Prosthetic Heart Valves by Multiplane Transesophageal Echocardiography
1997
The aim of this study was to evaluate the diagnostic increment of individually optimized axes in the assessment of pathological prosthetic valve regurgitation. Forty-two patients with pathologically regurgitant prostheses in the aortic (n = 21), mitral (n = 15), and tricuspid (n = 6) positions were examined by multiplane transesophageal echocardiography. The investigation was performed utilizing the transverse axis first, the longitudinal axis second, and the intermediate axes afterwards. The presence of regurgitation, the differentiation between trans- and perivalvular origin, and the localization of perivalvular leakages at the sewing ring were evaluated. Findings in the biplane and inter…
Papillary muscle relocation and mitral annuloplasty in ischemic mitral valve regurgitation: midterm results.
2014
Objectives The surgical approach for ischemic mitral regurgitation remains unclear. Many studies are in favor of adding the subvalvular procedure to mitral annuloplasty to reduce recurrent mitral regurgitation. This study reports the clinical and echocardiographic outcomes of papillary muscle relocation combined with mitral annuloplasty.Methods From 2003, 115 patients with severe ischemic mitral regurgitation who underwent papillary muscle relocation plus nonrestrictive mitral annuloplasty and coronary artery bypass grafting were retrospective analyzed. Patients' mean age was 52 ± 12.8 years, New York Heart Association class III or IV was 71%, and preoperative left ventricular ejection frac…
Implantation of Gore-Tex chordae on aortic valve leaflet to treat prolapse using "the chordae technique": surgical aspects and clinical results.
2008
Background Repair of prolapsed aortic valve leaflets has been considered a challenging technique for cardiac surgeons. In this paper we describe our surgical approach, "the chordae technique." It consists of the correction of aortic cusp prolapse by shortening the free margin length and of an adjustment of the leaflets coaptation height by anchoring the prolapsing cusp to the aortic wall at the sinotubular junction level. Methods Between February 2003 and December 2006, 26 patients with one or more prolapsed aortic leaflets underwent surgical repair using the new approach. The mean age of patients was 55 ± 10 years. There were 10 (38.5%) patients with grade II aortic valve regurgitation, 4 …
New Technique for Aortic Valve Functional Annulus Reshaping Using a Handmade Prosthetic Ring
2011
Background Despite a wide development in aortic leaflets repair techniques, aortic valve annuloplastic procedures are still poorly investigated. We present our aortic valve annuloplastic system consisting of a handmade prosthetic ring with 2 components for reshaping the aortic annulus and sinotubular junction (STJ) and illustrates our surgical approach and clinical results. Methods Since February 2003, 45 patients with aortic valve regurgitation underwent aortic annuloplasty using the new ring. Mean patient age was 58 ± 16 years (range, 46 to 76 years). The ring has 2 components: a circular ring used to undersize the circumference of the aortoventricular junction and 3-crown-like shape ring…
