Nowadays, dental diseases are one of the most common illnesses in the world. Some of them can lead to translocation of oral bacteria to the bloodstream causing intermittent bacteraemia. Therefore, a potential association between oral infection and cardiovascular diseases has been discussed in recent years as a result of adhesion of oral microbes to the heart valves. The aim of this study was to detect oral bacteria on pathologically changed heart valves not caused by infective endocarditis. In the study, patients with pathologically changed heart valves were involved...

BACKGROUND: Many patients with tetralogy of Fallot (TOF) who underwent surgical correction of their congenital cardiac malformation during infancy develop right ventricular dysfunction and exercise intolerance in the long term. The right ventricle (RV) dilates due to the development of severe pulmonary regurgitation (and secondary tricuspid insufficiency). To reduce RV dilation and improve exercise tolerance pulmonary valve replacement (PVR) is the common therapeutic strategy. Whether concomitant tricuspid valve repair (TVR) is beneficial in these pure volume-overload conditions is still unknown...

The indications for catheter-based structural and electrophysiological procedures have recently expanded to more complex scenarios, in which an accurate definition of the variable individual cardiac anatomy is key to obtain optimal results. Intracardiac echocardiography (ICE) is a unique imaging modality able to provide high-resolution real-time visualization of cardiac structures, continuous monitoring of catheter location within the heart, and early recognition of procedural complications, such as pericardial effusion or thrombus formation...

AIMS: We sought to evaluate the interaction of different aortic root phenotypes with self-expanding (SEV), balloon-expandable (BEV) and mechanically expanded (MEV) and the impact on significant aortic regurgitation. METHODS AND RESULTS: We included 392 patients with a SEV (N = 205), BEV (N = 107) or MEV (N = 80). Aortic annulus eccentricity index and calcification were measured by multi-slice CT scan. Paravalvular aortic regurgitation was assessed by contrast aortography (primary analysis) and transthoracic echocardiography (secondary analysis)...

BACKGROUND: The 30-day all-cause readmission rate after surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR) vary substantially. We conducted a systematic review and meta-analysis to examine the overall incidence, causes, and risk factors of 30-day all-cause readmission rate after SAVR and TAVR. METHODS: Eight medical research databases were searched; Cochrane, Medline, Embase, UpToDate, PROSPERO, National Guideline Clearinghouse, SweMed and Oria...

In this review article, we describe pulmonary valve replacement (PVR) late after repaired Tetralogy of Fallot (TOF). Since the introduction of surgical intervention for patients with TOF in 1945, surgical management of TOF has dramatically improved early survival with mortality rates, less than 2-3%. However, the majority of these patients continue to experience residual right ventricular outflow tract pathology, most commonly pulmonary valve regurgitation (PR). The patients are generally asymptomatic during childhood and adolescence and, however, are at risk for severe PR later which can result in exercise intolerance, heart failure, arrhythmias, and sudden death...

Mitral valve repair is becoming an increasingly frequent surgery for patients with mitral valve regurgitation. Iatrogenic coronary artery injury and ischemic myocardial compromise have been previously reported in the literature as a rare but serious complication of surgical mitral valve repair. This potentially life-threatening complication should be considered and quickly recognized during perioperative mitral valve repair or replacement to prevent morbidity and mortality. To increase awareness and to prevent this complication from being missed in the future, we present a case report of iatrogenic left circumflex artery dynamic occlusion and subsequent myocardial infarction from mitral valve annuloplasty resulting in severe peri-operative heart failure and death...

BACKGROUND: Electrophysiologic (EP) and structural interventions in adult congenital heart disease (ACHD) are typically completed during separate hospital encounters. With planning/coordination, these cases can be combined. OBJECTIVES: We hypothesized that this integrated approach would yield patient and health system benefits. METHODS: Consecutive ACHD patients undergoing combined interventions were matched to controls with identical but separate procedures...

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...

PURPOSE OF REVIEW: Analyze the current state of the art and the future perspectives of mitral interventions in clinical setting. RECENT FINDINGS: A systematic and critical review of the new mitral percutaneous therapies and imaging technologies is the basis to adopt the right treatment for each patient according to specific valve dysfunction and clinical presentation, waiting for definitive guidelines. While surgical mitral repair will remain the gold standard for low-risk healthy patients with degenerative mitral regurgitation (DMR), transcatheter mitral valve repair is becoming first line therapy in high risk patients with functional mitral regurgitation (FMR)...

Although medical students are rarely instructed in traffic medicine in Germany, they are obliged to inform their patients about their fitness to drive after having become a medical doctor. This article gives an overview on the fitness to drive for patients with syncope by referring to the driving license regulation and the current guidelines released by the department of traffic. The driving license regulation distinguishes between group 1 and group 2 drivers. Group 1 drivers drive vehicles with a total weight less than 3...

Objectives: In patients with symptomatic aortic valve disease who are at intermediate to high risk for open surgical aortic valve replacement, transcatheter aortic valve replacement (TAVR) decreases overall mortality and improves quality of life. Hypertension (HTN) after TAVR has been associated with improved cardiac function and short-term survival but its effect on survival over 1 year is unclear. Our study aims to evaluate the effect of HTN following TAVR on short-term and long-term clinical and echocardiographic outcomes...

BACKGROUND: The lack of an antidote against factor Xa inhibitors in case of major bleeding or need for urgent surgery is a concern to clinicians. Guidelines on managing major bleeding in patients under anticoagulation with a factor Xa inhibitor suggest several hemostatic agents to reverse the effect, but there is no consensus regarding the choice of drug or appropriate dose. The ability of prothrombin complex concentrate, activated prothrombin complex concentrate, and recombinant factor VIIa to reverse the effect of factor Xa inhibitors has been evaluated in animal studies, in vitro studies, and healthy volunteers, but not yet in randomized clinical studies...

The case is reported of a 55 year-old woman, with a previously known congenital septal defect, who was admitted to the emergency department with a diagnosis of meningoencephalitis, septic shock, and rapid clinical deterioration. Echocardiography revealed a vegetation occupying the right-side heart. Endocarditis affectation of the septal defect, aortic and tricuspid valves was noted and blood cultures were positive for Staphylococcus aureus. Urgent surgical treatment was performed whereby the ventricular septal defect was closed, a meticulous debridement of the affected area was conducted, and the aortic and tricuspid valves were replaced...

Herein is presented the case of an 83-year-old male patient in cardiogenic shock with acute aortic regurgitation that occurred six years after aortic valve replacement (AVR) with a 23 mm Trifecta™ valve. Prosthesis endocarditis was initially suspected because of a floating structure attached to the aortic valve that was visible on echocardiography. Emergency redo-AVR surgery was performed, but no signs of endocarditis were found intraoperatively. Hence, cusp tearing of the implanted bioprosthesis was considered to be the reason for the severe aortic regurgitation...

BACKGROUND: Myxomatous mitral valve disease (MMVD) is one of the most prevalent valvular heart diseases, while back pain, neck pain and upper-extremity numbness are some of the most common complaints in outpatient settings. Decreased thoracic kyphosis (straight back) is a known cause of hastening back or neck problems, radiculopathy, or even myelopathy. The study aim was to examine the relationship between MMVD, straight back, and the need for cervical fusion. METHODS: In this single-center retrospective study, patients who underwent mitral valve repair or replacement due to MMVD (cases) based on age, gender and body mass index (BMI), were matched with patients who underwent coronary artery bypass grafting (CABG) surgery and had no history of mitral valve disease (controls)...

Bartonella spp. are emerging pathogens that are reported as the cause of blood culture-negative endocarditis ( BCNE). However, echocardiographic features and assessment of this endocarditis remains unclear. Four patients with B. henselae endocarditis were identified. All patients had underlying cardiac conditions: rheumatic heart disease in three, congenital heart disease in one. Evidence of vegetations was found on the aortic valve in all patients with large, highly mobile vegetations and severely destroyed valves demonstrated by the transthoracic echocardiogram leading to severe aortic regurgitation and heart failure...

A 72-year-old man was admitted to our hospital because of dyspnea. He had a history of cardiac resynchronization therapy for congestive heart failure due to dilated cardiomyopathy 6 months previously. Echocardiography revealed severe functional mitral regurgitation which had been mild 6 months before. Because medical treatment was ineffective, on-pump beating mitral valve replacement using a bioprosthesis was performed to prevent reperfusion injury. The patient was easily weaned from cardiopulmonary bypass with low-dose inotropic support and scheduled intra-aortic balloon pump...
