INTRODUCTION: The coexistence of significant mitral regurgitation (MR) and severe aortic stenosis is prevalent, has a prognostic impact and makes treatment in the elderly population a complex issue. The aim of this study is to determine the prevalence of significant MR among a population of octogenarians and its influence on treatment and prognosis. METHODS: We used the data from PEGASO (Pronóstico de la Estenosis Grave Aórtica Sintomática del Octogenario), a prospective registry that consecutively included 928 patients aged ≥80 years with severe symptomatic aortic stenosis...

For the year 2017, more than 21,000 published references can be found in PubMed when entering the search term "cardiac surgery". This review focusses on conventional cardiac surgery, considering the new interventional techniques only if they were directly compared to classic techniques but also entails aspects of perioperative intensive care management. The publications last year provided a plethora of new and interesting information that helped to quantify classic surgical treatment effects and provided new guidelines for the management of structural heart disease, which made comparisons to interventional techniques easier...

BACKGROUND: The concomitant presence of mitral stenosis (MS) in the setting of symptomatic aortic stenosis represent a clinical challenge. Little is known regarding the outcome of mitral stenosis (MS) patients undergoing transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR). Therefore, we sought to study the outcome of MS patients undergoing aortic valve replacement (AVR). METHOD: Using weighted data from the National Inpatient Sample (NIS) database between 2011 and 2014, we identified patients who were diagnosed with MS...

In 1975, Morganroth and colleagues reported that the increased left ventricular (LV) mass in highly trained endurance athletes versus nonathletes was primarily due to increased end-diastolic volume while the increased LV mass in resistance trained athletes was solely due to an increased LV wall thickness. Based on the divergent remodelling patterns observed, Morganroth and colleagues hypothesised that the increased "volume" load during endurance exercise may be similar to that which occurs in patients with mitral or aortic regurgitation while the "pressure" load associated with performing a Valsalva manoeuvre (VM) during resistance exercise may mimic the stress imposed on the heart by systemic hypertension or aortic stenosis...

A 36-year-old pregnant woman with a history of rheumatic heart disease and prior aortic valve replacement and mitral valve repair presented to an outside hospital with severe aortic stenosis. The patient had a cardiac arrest upon labor induction and underwent a transcatheter aortic valve replacement (TAVR), which dislodged two days later. Five months later, the patient underwent removal of the dislodged TAVR and a Ross procedure at the authors' institution. The patient was stable upon discharge, with minimal aortic and pulmonary regurgitation...

Background: Anderson-Fabry disease is an X-linked inherited disease, which manifests in a different manner depending on gender and genotype. Making a working diagnosis of Anderson-Fabry disease is difficult because of several reasons: (a) that it is a multiorgan disease with wide variety of phenotypes, (b) different timelines of presentation, (c) gender differences, and (d) possible coexistence with other comorbidities. Late-onset/cardiac type of presentation with minimal involvement of other organs can additionally make diagnosis difficult...

A rare case of mitral stenosis after mitral valve repair for non-rheumatic mitral regurgitation is presented. An 81-year-old woman who had undergone mitral valve repair using an annuloplasty ring 12 years earlier, was referred to our hospital because of dyspnea during exertion. As echocardiography revealed severe mitral stenosis, and redo surgery was carried out. During the surgery, fibrous tissue covered the annuloplasty ring and extended onto both leaflets of the mitral valve, which narrowed its orifice, by rendering the leaflets stiff and immobile...

Although nonstructural dysfunction of a bioprosthesis caused by pannus formation or native valve attachment has been well described, structural valve deterioration( SVD) caused by calcification or tear of a bioprosthesis, especially a bovine pericardial valve, is very rare in the tricuspid position. We report a case of redo tricuspid valve surgery for SVD 14 years after tricuspid valve replacement( TVR) using a Carpentier-Edwards Perimount (CEP) pericardial valve. A 71-year-old woman was referred to our hospital because of exertional dyspnea and pre-syncope...

Transcatheter mitral valve replacement (TMVR) is a novel approach for treatment of severe mitral regurgitation. A number of TMVR devices are currently undergoing feasibility trials using both transseptal and transapical routes for device delivery. Overall experience worldwide is limited to fewer than 200 cases. At present, the 30-day mortality exceeds 30% and is attributable to both patient- and device-related factors. TMVR has been successfully used to treat patients with degenerative mitral stenosis (DMS) as well as failed mitral bioprosthesis and mitral repair using transcatheter mitral valve-in-valve (TMViV)/valve-in-ring (ViR) repair...

Colin M Barker
Mitral regurgitation (MR) affects more than 2 million people in the United States annually and is the second leading cause of heart valve disease after aortic stenosis. Surgical intervention is the currently accepted treatment of choice in patients with either symptomatic degenerative MR or asymptomatic MR with pulmonary hypertension, atrial fibrillation, or left ventricular dysfunction. Based on robust evidence from clinical trials, the MitraClip Transcatheter Mitral Valve Repair system (Abbott Vascular) was approved in the United States for commercial use in 2013...

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...

RATIONALE: Inadvertent pacemaker/defibrillator lead placement into the left ventricle is an unusual cardiac device-related complication and its diagnosis is not always easy and often misunderstood. Thromboembolic events are frequently associated with this procedural complication. Percutaneous lead extraction should be performed when diagnosis is made early after device implantation while long-life oral anticoagulation is a wise option when the diagnosis is delayed and the lead is not removed...

BACKGROUND: Mucopolysaccharidosis (MPS) type III, Sanfilippo Syndrome, is an autosomal recessive lysosomal storage disorder. MPS I and II patients often develop cardiac involvement leading to early mortality, however there are limited data in MPS III. The objective of this study is to describe cardiac abnormalities in a large group of MPS III patients followed in a longitudinal natural history study designed to determine outcome measures for gene transfer trials. METHODS: A single center study of MPS III patients who were enrolled in the Nationwide Children's Hospital natural history study in 2014...

Mitral stenosis (MS) is characterized by obstruction of left ventricular inflow as a result of narrowing of the mitral valve orifice. Although its prevalence has declined over the last decade, especially in developed countries, it remains an important cause of morbidity and mortality.  The most often cause of MS worldwide is still postrheumatic mitral valve disease. However, in developed countries, degenerative or calcific changes cause MS in a siginificant proportion of patients. Although the range of treatment for mitral valve disease has grown over the years in parallel with transcatheter therapies for aortic valve disease, these improvements in mitral valve disease therapy have experienced slower development...

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...

OBJECTIVES: To elucidate the effect of tricuspid annuloplasty concomitant with left-sided valve surgery on the right heart in patients with mild or more tricuspid regurgitation (TR). METHODS: We enrolled 78 patients with mild or more TR who underwent left-sided valve surgery. Forty-three patients underwent only left-sided valve surgery (group non-T) and 35 underwent concomitant tricuspid annuloplasty (group T). Echocardiographic changes between the preoperative and 1-year follow-up periods were compared...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is a safe and effective alternative to surgical aortic valve replacement (SAVR) for the treatment of severe aortic valve stenosis (AS). The impact of concomitant baseline elevated pulmonary artery pressures on outcomes after TAVI has not been established, since different studies used different definitions of pulmonary hypertension (PH). OBJECTIVE: To determine the association of PH with early and late cardiac and all-cause mortality after TAVI...

BACKGROUND AND AIM OF THE STUDY: Rheumatic mitral stenosis (RMS) is an autoimmune, progressive destructive valve disease occurring as a sequele of streptococcal infection. Epidemiological studies support an association of vitamin D deficiency with initial susceptibility and severity of autoimmune diseases. The aim of the present study was to assess serum level of 25 hydroxyvitamin D in subjects of RMS and assess if any correlation exists with serum levels of vitamin D and severity of disease along with calcification assessed semi-quantitatively by echocardiography by applying Wilkins score...

In this heart failure patient, TEE images confirm the presence of the persistent left SVC with a dilated coronary sinus, severe mitral regurgitation, and aortic stenosis. Computed tomography reveals an isolated persistent left SVC and rules out anomalous pulmonary vein drainage or additional congenital disease.
