β-Blockers are useful drugs in several clinical cardiologic scenarios. Their use in the perioperative period and in critically ill patients is increasing, but their effect on clinically relevant outcomes remains controversial. Long-acting β-blockers can have detrimental effects that are difficult to be counteracted in these settings. The authors describe the possible clinical uses of ultra-short-acting β-blockers (esmolol and landiolol) in the perioperative period and in critically ill patients because these drugs have the beneficial effects of β-blockers, but do not have the detrimental effects of long-acting agents...

Perioperative echocardiography, especially transesophageal echocardiography, is of paramount importance in evaluating and managing refractory hypotension, a potential cause of which is systolic anterior motion (SAM) of anterior mitral leaflet. Dynamically moving anterior mitral valve leaflet towards the left ventricular outflow tract (LVOT) is described as SAM. Although SAM was initially observed in patients with hypertrophic cardiomyopathy, it can also be seen in patients with complex dynamic anatomy of the left ventricle...

OBJECTIVES: Scanty data are available on 'second cross-clamping' following mitral valve repair in contemporary practice. The aim of this study was to evaluate the incidence, causes and outcomes of this event in patients referred for mitral repair for severe degenerative mitral regurgitation (MR). METHODS: The study population included 2318 patients with severe degenerative MR referred for mitral repair. A second cross-clamping was performed in 94 (4%) patients. Causes of the second cross-clamping, revising repair procedures, immediate echocardiographic outcomes and postoperative course were assessed and compared with the 'single cross-clamping cases' (2224 patients used as control)...

OBJECTIVES: We aimed to evaluate the incidence and midterm clinical outcomes of left ventricular obstruction (LVO) after transcatheter aortic valve implantation (TAVI). BACKGROUNDS: LVO is occasionally unmasked following valve replacement for severe aortic stenosis. However, little is known about the prevalence and effects of LVO after TAVI. METHODS: A total of 158 patients who underwent TAVI in our center between October 2013 and November 2015 received echocardiographic evaluations at baseline; before hospital discharge; and at 3, 6, and 12 months after TAVI...

BACKGROUND: We assessed the mitral annular motion after mitral valve repair with the Sorin Memo 3D® (Sorin Group Italia S.r.L., Saluggia, Italy), which is a unique complete semirigid annuloplasty ring intended to restore the systolic profile of the mitral annulus while adapting to the physiologic dynamism of the annulus, using transesophageal real-time three-dimensional echocardiography. METHODS: 17 patients (12 male; mean age 60.4 ± 14.9 years) who underwent mitral annuloplasty using the Memo 3D ring were investigated...

Emergent ascending aortic replacement and extended myectomy were performed in a woman with acute aortic dissection who was aged 63 years. Preoperative transthoracic echocardiography performed in the intensive care unit showed only slight left ventricular outflow tract (LVOT) obstruction, but intraoperative transesophageal echocardiography after induction of anesthesia revealed pericardial effusion, systolic anterior motion(SAM), and associated mitral regurgitation(MR). Perioperative SAM and MR are sometimes facilitated under various hemodynamic conditions, but in this case, the left ventricular wall was thick and LVOT appeared to be obstructive by a hypertrophied septum...

OBJECTIVES: Residual midventricular obstruction after transaortic myectomy may lead to recurrent symptoms and reoperation in patients with hypertrophic cardiomyopathy and long-segment septal hypertrophy. A combined transaortic and transapical approach to septal myectomy during initial operation allows for the complete relief of subaortic and midventricular gradients and may reduce the risk of poor late functional results. METHODS: We analyzed the early outcomes of 86 patients aged 18 years or more who underwent combined transaortic and transapical septal myectomy for left ventricular outflow tract obstruction due to systolic anterior motion and midventricular obstruction or cavitary obliteration due to apical hypertrophic cardiomyopathy...

Systolic anterior motion (SAM) of the mitral valve or chordate is one characteristic seen in hypertrophic cardiomyopathy (HCM) either in obstructive or non-obstructive phenotypes. More often than not, the obstruction is caused by valvular rather than chordal SAM. We describe the role of echocardiography in identifying the actual anatomical location of the mitral valve apparatus involved in SAM and in assessing consequent left ventricular outflow tract (LVOT) obstruction in an otherwise asymptomatic patient...

OBJECTIVES: Systolic anterior motion (SAM) can be an insidious complication after mitral repair. Predicting SAM represents a challenge, even for very experienced mitral valve surgeons. The goal of this pilot work was to illustrate for the first time, a computational software able to calculate and prevent SAM during mitral repair. METHODS: Using MATLAB graphical user interface, a clinical software to predict SAM, we tested the performances of the software on 136 patients with degenerative mitral valves undergoing repair with standard techniques...

BACKGROUND: Hypertrophic cardiomyopathy (HCM) is a primary myocardial disease characterized by left ventricular hypertrophy in the absence of other etiologies. Clinical presentation may vary from asymptomatic to sudden cardiac death. Medical treatment is the first-line therapy for symptomatic patients. Extended left ventricular septal myectomy is the procedure of choice if medical treatment is unsuccessful or intolerable. MAYO CLINIC EXPERIENCE: More than 3,000 patients have had septal myectomy for HCM at the Mayo Clinic (MN, USA) from 1993 to 2016...
