Epidemiology of acute kidney injury among paediatric patients after repair of anomalous origin of the left coronary artery from the pulmonary artery.

Eur J Cardiothorac Surg 2019 Apr 21. Epub 2019 Apr 21.

Department of Anesthesiology, Fuwai Hospital, Chinese Academy of Medical Sciences, Peking Union Medical College, Beijing, China.

Objectives: Acute kidney injury (AKI) is a prevalent complication after the surgical repair of paediatric cardiac defects and is associated with poor outcomes. Insufficient renal perfusion secondary to severe myocardial dysfunction in neonates is most likely an independent risk factor in patients undergoing repair for anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA). We retrospectively investigated the epidemiology and outcomes of children with ALCAPA who developed AKI after repair. Read More

Regulatory approval review of transcatheter mitral valve repair - Difference in the indication between the USA and Japan.

J Cardiol 2019 Apr 17. Epub 2019 Apr 17.

Pharmaceuticals and Medical Devices Agency, Tokyo, Japan.

The indication for MitraClip (Abbott Vascular, Santa Clara, CA, USA) in the USA is degenerative mitral regurgitation (DMR), but the Japanese indication includes both DMR and functional mitral regurgitation (FMR), in patients without severe left ventricular dysfunction. One of the reasons for this difference is that the Japanese Circulation Society submitted a formal request to the Japanese government for early approval of MitraClip for both DMR and FMR on the basis of unmet medical need for MR patients resistant to medical therapy, but at prohibitive risk for mitral valve surgery. Here, we describe the regulatory approval review process of MitraClip in Japan. Read More

On the simulation of mitral valve function in health, disease, and treatment.

J Biomech Eng 2019 Apr 20. Epub 2019 Apr 20.

Gorman Cardiovascular Research Group, Department of Surgery, University of Pennsylvania, Philadelphia, PA.

The mitral valve (MV) is the heart valve that regulates blood ?ow between the left atrium and left ventricle (LV). In situations where the MV fails to fully cover the left atrioventricular ori?ce during systole, the resulting regurgitation causes pulmonary congestion, leading to heart failure and/or stroke. The causes of MV insuf?ciency can be either primary (e. Read More

Effect of Progressive Left Ventricular Dilatation on Degree of Mitral Regurgitation Secondary to Mitral Valve Prolapse.

Am J Cardiol 2019 Mar 13. Epub 2019 Mar 13.

Internal Medicine (Division of Cardiology), Baylor University Medical Center, Baylor Scott & White Health, Dallas, Texas.

Described herein is a 71-year-old man who at age 61 was found by echocardiogram to have severe mitral regurgitation (MR) from mitral valve prolapse. During the subsequent 9 years the MR progressively lessened as his left ventricular cavity dilated and his ejection fraction progressively fell such that just before orthotopic heart transplantation the degree of MR was no longer severe, and the prolapse of the mitral leaflets had disappeared. This report describes this unique patient. Read More

Flexible and comprehensive patient-specific mitral valve silicone models with chordae tendineae made from 3D-printable molds.

Int J Comput Assist Radiol Surg 2019 Apr 17. Epub 2019 Apr 17.

Department of Cardiac Surgery, University Hospital Heidelberg, Heidelberg, Germany.

Purpose: Given the multitude of challenges surgeons face during mitral valve repair surgery, they should have a high confidence in handling of instruments and in the application of surgical techniques before they enter the operating room. Unfortunately, opportunities for surgical training of minimally invasive repair are very limited, leading to a situation where most surgeons undergo a steep learning curve while operating the first patients.

Methods: In order to provide a realistic tool for surgical training, a commercial simulator was augmented by flexible patient-specific mitral valve replica. Read More

Chymase uptake by cardiomyocytes results in myosin degradation in cardiac volume overload.

Heliyon 2019 Apr 4;5(4):e01397. Epub 2019 Apr 4.

Birmingham Veteran Affairs Medical Center, USA.

Background: Volume overload (VO) of isolated mitral regurgitation (MR) or aortocaval fistula (ACF) is associated with extracellular matrix degradation and cardiomyocyte myofibrillar and desmin breakdown. Left ventricular (LV) chymase activity is increased in VO and recent studies demonstrate chymase presence within cardiomyocytes. Here we test the hypothesis that chymase within the cardiomyocyte coincides with myosin and desmin breakdown in VO. Read More

[Tricuspid regurgitation and indications for treatment].

G Ital Cardiol (Rome) 2019 Apr;20(4):27-35

Dipartimento Cardiovascolare, Azienda Sanitaria Universitaria Integrata di Trieste.

Tricuspid regurgitation is a frequent valvular heart disease, particularly in the elderly and in association with other left-sided heart diseases. It has an adverse prognostic impact, with progressively increasing mortality as the degree of regurgitation increases. Isolated or combined (with mitral and/or aortic) surgery remains the treatment of choice, provided operative risk is acceptable. Read More

[What role for transcatheter mitral valve replacement?]

G Ital Cardiol (Rome) 2019 Apr;20(4):20-26

Cardiologia Clinica-UTIC ed Interventistica, IRCCS Policlinico San Donato, San Donato Milanese (MI).

Despite the safety and efficacy of transmitral valve repair techniques, transcatheter mitral valve replacement (TMVR) has emerged as a potential treatment option for patients with severe mitral regurgitation at high or prohibitive surgical risk. To date, over 250 high-risk patients with severe mitral regurgitation have been treated with 10 different TMVR devices, demonstrating the feasibility of this technique. Parallel to the potential advantages of this procedure (reproducible mitral regurgitation reduction, possibility of targeting all potential anatomic variations), many challenges has emerged during the design and implantation phases.

Anesthesiological Management in Transcatheter Mitral Valve Repair With MitraClip: Beyond the EVEREST Criteria.

Semin Cardiothorac Vasc Anesth 2019 Apr 17:1089253219842650. Epub 2019 Apr 17.

1 AORN Ospedali dei Colli, Monaldi Hospital, Naples, Italy.

Percutaneous mitral valve repair with the MitraClip system recently emerged as a viable and less invasive therapeutic option in patients with severe mitral regurgitation deemed to be high-risk surgical candidates. Mitral valve morphology and geometry features are key elements for MitraClip eligibility. In the setting of functional mitral regurgitation, the presence of a leaflet coaptation gap due to advanced left ventricle remodeling can be a potential exclusion criterion for MitraClip therapy.

Noteworthy Literature Published in 2018 for Cardiothoracic Anesthesiologists.

Semin Cardiothorac Vasc Anesth 2019 Apr 15:1089253219842651. Epub 2019 Apr 15.

1 Harvard Medical School, Brigham and Women's Hospital, Boston, MA, USA.

The year 2018 was marked by high-quality, impactful articles spanning the basic, translational, and clinical spectrum in the field of cardiothoracic anesthesia. In this article, we present several hand-picked articles from the past year that we feel were the most significant in shaping our specialty. Large multicenter, randomized controlled trials presenting clinical outcome data dominated the publishing arena: is a restrictive red blood cell transfusion strategy superior to a liberal red blood cell transfusion strategy during cardiopulmonary bypass? Does a low mean arterial blood pressure strategy during cardiopulmonary bypass increase stroke incidence? Does the obesity paradox apply to cardiac surgery? Advancing technology continues to revolutionize our field: can the MitraClip be used to effectively treat secondary mitral regurgitation? Can stem cells improve cardiac function in patients with left ventricular assist devices? These studies allow us to shape our practice in an evidence-based manner, so that we may evolve as a specialty and deliver the best care to our patients. Read More

Successful transcatheter mitral valve replacement in a patient with bioprosthetic valvular degeneration and severe regurgitation.

Turk Kardiyol Dern Ars 2019 Apr;47(3):228-231

Department of Cardiology, İstanbul Medipol University Faculty of Medicine, İstanbul, Turkey.

The implantation of aortic transcatheter heart valves has been successfully performed throughout the world in hundreds of patients with severe dysfunction of a degenerated mitral bioprosthesis or those at high surgical risk for re-operation. The transseptal approach may be more technically challenging, but is a less invasive procedure and may have a lower mortality rate compared with a transapical approach, and also offers a quick patient recovery. This report is a description of a rare case in Turkey: a successful transseptal mitral valve replacement in a case of a failed bioprosthetic valve. Read More

Physical performance as a predictor of midterm outcome after mitral valve surgery.

Heart Vessels 2019 Apr 10. Epub 2019 Apr 10.

Department of Cardiology, Sakakibara Heart Institute, 3-16-1 Asahicho, Fuchu, 183-0003, Tokyo, Japan.

The usefulness of performing physical function assessments for evaluating clinical outcomes after all cardiac surgeries has been reported. However, no studies have evaluated the relationship between physical function and prognosis in patients undergoing cardiac open surgery with mitral valve regurgitation (MR). This study investigated whether physical assessment, such as the short physical performance battery (SPPB), could predict unplanned readmission events in patients undergoing mitral valve surgery due to MR.

The Impact of a New "Inverted Arch" Prosthetic Annuloplasty Ring on the Mitral Valve's 3-D Motion: An Experimental Ex-Vivo Study.

Bioengineering (Basel) 2019 Apr 8;6(2). Epub 2019 Apr 8.

Department of Medical Direction of University Hospital of Novara, Corso Mazzini 18, 28100 Novara, Italy.

This experimental study aimed to evaluate the ex-vivo three-dimensional (3-D) motion of the Inverted Arch Ring (IAR), an innovative new design concept for a flexible incomplete annuloplasty prosthesis with an incorporated stabilizing rigid arch that can be used in correcting mitral valve regurgitation. Twenty explanted porcine hearts were placed in a circulation simulation system. Ultrasonometry transducers implanted in the mitral annulus were used to measure the 3-D valvular motion during a simulated cardiac cycle. Read More

Left atrial spontaneous echo contrast: relationship with clinical and echocardiographic parameters.

Echo Res Pract 2019 Apr 1. Epub 2019 Apr 1.

M Suwa, Department of Cardiovascular Disease, Hokusetsu General Hospital, Takatsuki, Japan.

Spontaneous echo contrast (SEC) is known as a precursor of thrombus formation reflecting blood stasis in cardiac chambers and major vessels. Transesophageal echocardiography plays a pivotal role in detecting and grading SEC in the left atrial (LA) cavity. Assessing LA SEC can identify patients at increased risk for thromboembolic events.

Transient Systolic Anterior Motion of the Anterior Mitral Valve Leaflet in a Critical Care Patient with a Structurally Normal Heart.

Cureus 2019 Jan 25;11(1):e3963. Epub 2019 Jan 25.

Internal Medicine, Abington Memorial Hospital, Abington, USA.

Systolic anterior motion (SAM) is defined as the displacement of the anterior mitral leaflet towards the left ventricular outflow tract, which results in left ventricular outflow tract obstruction (LVOTO). The SAM of the anterior mitral leaflet is a well-established phenomenon in hypertrophic obstructive cardiomyopathy (HOCM), but its occurrence in a structurally healthy heart is uncommon. We present a critical care patient with presumed septic shock whose blood pressure was previously controlled by fluid resuscitation and vasopressors. Read More

Current status and future perspective of structural heart disease intervention.

J Cardiol 2019 Apr 5. Epub 2019 Apr 5.

Heart Center Bonn, Department of Medicine II, University Hospital Bonn, Germany. Electronic address:

Valvular heart diseases are one of the most frequent causes for heart failure. Degenerative diseases of the aortic and mitral valve as well as a dysfunctional tricuspid valve disease result in a worse clinical outcome if severe. Minimal-invasive, surgical and/or catheter-based structural heart disease (SHD) interventions have recently seen a dramatic increase. Read More

Morphological Assessment of the Tricuspid Apparatus and Grading Regurgitation Severity in Patients With Functional Tricuspid Regurgitation: Thinking Outside the Box.

JACC Cardiovasc Imaging 2019 Apr;12(4):652-664

Department of Cardiac, Thoracic, and Vascular Sciences, University of Padua School of Medicine, Padua, Italy; IRCCS, Instituto Auxologico Italiano, S. Luca Hospital, University of Milano-Biococca, Milan, Italy.

Current guidelines recommend transthoracic echocardiography to assess patients with functional tricuspid regurgitation (FTR) because it provides information regarding the presence of structural abnormalities of the tricuspid valve (TV), allows measurement of tricuspid annulus diameter, and evaluates severity of FTR by integrating data obtained from 2D and Doppler echocardiography. Critical components of the noninvasive evaluation include information regarding TV anatomy, tricuspid regurgitation severity, right ventricular size and systolic function, and associated findings such as estimated pulmonary artery pressure. However, most of the parameters included in the current recommendations to assess FTR are derived from the experience and knowledge developed about the mitral valve and have been transferred from the left to the right side of the heart without accounting for differences in anatomy of the tricuspid and mitral apparatus or for differences in hemodynamic environment in which the TV operates compared to its left counterpart.

Left ventricular free-wall rupture, a potentially lethal mechanical complication of acute myocardial infarction: an unusual and illustrative case report.

BMC Cardiovasc Disord 2019 Apr 3;19(1):80. Epub 2019 Apr 3.

Departamento de Fisiología, Centro Universitario de Ciencias de la Salud, Universidad de Guadalajara, Sierra Mojada 950, Col. Independencia, Guadalajara, Jalisco, México.

Background: There are three major mechanical complications after acute myocardial infarction: left ventricular free-wall rupture, ventricular septum rupture and acute mitral valve regurgitation. The left ventricular free-wall rupture is a serious and often lethal complication following an ST elevation myocardial infarction. However, very rarely this rupture can be contained by the pericardium, forming a pseudoaneurysm. Read More
