BACKGROUND: Laron syndrome (LS), which can be defined as primary growth hormone resistance or insensitivity, is a rare genetic disease inherited by an autosomal recessive trait. Although it is undistinguishable from growth hormone deficiency, LS has high levels of growth hormone, but insulin-like growth factor (IGF-1) cannot be synthesized. Mecasermin treatment is the only option for the patients who suffer from LS. This study aims to research cardiac findings of children with LS, who receive treatment with mecasermin...

We sought to present our institutional protocol to manage incomplete initial repair of degenerative mitral regurgitation and to evaluate its mid-term outcomes. Eight hundred and fifteen patients with degenerative mitral insufficiency undergoing mitral valve repair were investigated in this study. The initial repair attempt was incomplete in 48 patients, leaving a degree of residual regurgitation > mild, and an elevated transmitral gradient or systolic anterior motion (SAM). These patients were further treated with medication or mitral valve re-repair or replacement under reinstituted cardiopulmonary bypass...

BACKGROUND: Deep hypothermic circulatory arrest (DHCA) is often avoided in patients with concomitant ascending aortic pathology when treating other cardiac disease to avoid increased risk of morbidity and mortality. We hypothesized that the use of DHCA with retrograde cerebral perfusion (RCP) does not add incremental risk to ascending aortic replacement alone in the setting of concomitant cardiac surgery. METHODS: 408 ascending aortic ± hemiarch replacements and aortic (root)/mitral/tricuspid valve(s), CABG, or MAZE procedures were performed for concomitant cardiac disease...

Importance: Timing of surgical aortic valve replacement (SAVR) in patients with aortic valve stenosis and previous stroke for the risk of recurrent stroke is insufficiently investigated. Objective: To evaluate the association of time elapsed between previous stroke and SAVR with the risk of recurrent perioperative stroke, major adverse cardiovascular events (MACE), and mortality among patients with aortic valve stenosis. Design, Setting, and Participants: This cohort study using data from Danish administrative registries included all patients with aortic valve stenosis older than 18 years who underwent SAVR between 1996 and 2014 (n = 14 030)...

A 76-year-old woman who had been on hemodialysis for 3 years developed ischemic mitral valve insufficiency, tricuspid insufficiency, and chronic atrial fibrillation, and underwent cardiac surgery. On the 4th postoperative day, she experienced a sudden disturbance of consciousness, aphasia, and limb ataxia. Brain computed tomography and magnetic resonance imaging showed no abnormalities. Wernicke's encephalopathy was suspected and the patient was given vitamin B1, whereupon her symptoms gradually improved. On the 42nd postoperative day, she was free of neurological symptoms and discharged...

Congestive heart failure (CHF) is characterized by reduced heart rate variability. Although various methods to achieve parasympathetic withdrawal and sympathetic activation have been documented, stimulation of the vagal nerve (that is, vagal maneuvers) has not often been used to assess the autonomic impairment associated with disease progression in veterinary species. In this study, we investigated cardiac autonomic control in a naturally occurring canine model of mitral insufficiency by means of individual responses to oculocardiac reflex...

A 76-year-old woman, who had a history of ocular sarcoidosis, was incidentally found to have a huge pulmonary artery aneurysm, along with aortic, mitral and tricuspid valve insufficiency. She underwent pulmonary artery plication along with surgeries for 3 valves. A specimen of the slightly enlarged ascending aorta revealed the involvement of sarcoidosis in the aortic wall. The systemic granulomatous inflammation process of sarcoidosis possibly affected the valvular and vascular pathology. Herein, we report a rare case of aortic sarcoidosis complicated by a pulmonary artery aneurysm...

PURPOSE: We describe a case of Lyme endocarditis which, to our knowledge, is the first reported case confirmed by molecular diagnostics in the United States. BACKGROUND: Valvular involvement as a manifestation of Lyme carditis is rare4 . The first case describing a possible association between Lyme disease and cardiac valvular disease in the United States was published in 19935 . Since that time, there have been 2 cases of Lyme endocarditis confirmed by Borrelia positive 16S rRNA polymerase chain reaction (PCR) and sequencing from valvular tissue8,10 and reported from Europe...

For the first time, the European Society of Cardiology and the European Association for Cardio-Thoracic Surgery have joined forces to develop consensus guidelines for the management of atrial fibrillation (AF). One of the main issues is the integrated care of patients with AF, with emphasis on multidisciplinary teams of general physicians, cardiologists, stroke specialists and surgeons, together with the patient's involvement for better management of AF. These guidelines also help in the detection of risk factors and concomitant cardiovascular diseases, stroke prevention therapies, including anticoagulation and antiplatelet therapies after acute coronary episodes, major haemorrhages or strokes...

BACKGROUND: Cardiovascular disease accounts for 35% to 50% of the causes of mortality in chronic kidney disease. The majority of patients in substitution therapy in Mexico are subdialyzed owing to limited economic resources. This produces more cardiac deterioration than described in the statistics and has a direct impact on the prognosis of kidney transplantation. The aim of this work was to demonstrate and to quantify the improvement in the echocardiographic parameters 6 months after renal transplantation in patients with stable renal function...

We present the case of a 72-year-old woman diagnosed with rheumatic fever at the age of 6. In 1972, she was diagnosed with mitral valve insufficiency and mitral valve stenosis, then in 1974, a decision was made to perform mitral valve replacement surgery with a 32-mm Braunwald-Cutter ball cage prosthesis. An echocardiogram performed in 2014 revealed normal biventricular systolic function, mechanical prosthesis in mitral position with maximum speed of 1.9 m/s, maximum gradient of 15 mmHg, mean gradient of 6 mmHg, severe tricuspid valve insufficiency, inferior vena cava measuring 15 mm with more than 50% collapse and pulmonary artery systolic pressure of 40 mmHg...

OBJECTIVE: Planned mitral repair strategies are generally established from preoperative echocardiography; however, specific details of the repair are often determined intraoperatively. We propose that three-dimensional printed, patient-specific, dynamic mitral valve models may help surgeons plan and trial all the details of a specific patient's mitral repair preoperatively. METHODS: Using preoperative echocardiography, segmentation, modeling software, and three-dimensional printing, we created dynamic, high-fidelity, patient-specific mitral valve models including the subvalvular apparatus...

Congenital mitral valve (MV) dysplasia is a relatively rare and highly complex cardiac disease. We sought to provide a comprehensive analysis of the current surgical techniques for treating mitral valve insufficiency and the results of mitral valve repair at our institution. Between 1972 and 2017, 104 consecutive patients underwent surgical repair of congenital MV dysplasia-insufficiency at our institution. Among these, 59 patients presented with MV insufficiency (or prevalent MV insufficiency) and were part of the study...

Introduction: Excess dilatation of the left atrium >65 mm is known in the literature as gigantic atrium. This dilation is most commonly encountered in the mitral insufficiency of rheumatic etiology, but also in severe prolapses of the mitral valve, permanent atrial fibrillation, and at the left right shunt with cardiac insufficiency. Case report: In this paper is presented a case study of echocardiographically verified giant thrombus in left atrium in a 50 years old female patient aged 50 hospitalized because of tiredness, choking, heartburn and urinary tract symptoms...

BACKGROUND: Artificial chord implantation has become one of the most applied techniques for mitral valve repair (MVR). Many techniques have been described with the goal of optimizing neochord implantation. A new annuloplasty device designed to simplify the determination of appropriate neochord length has been recently introduced. We will describe our initial experience with this new device. METHODS: The semirigid device is equipped with removable loops on the posterior aspect of the ring...
