Rheumatic heart disease (RHD) is a major health hazard in most developing countries as well as sporadically in developed economies with high prevalence rates. Mitral stenosis is among the important morbid valvular conditions accounting for 25% of RHD cases. Percutaneous transmitral commissurotomy (PTMC) using Inoue balloon is the standard treatment for severe mitral stenosis with favorable Wilkins score. In certain cases it is difficult to cross mitral valve (MV) either due to dilated left atrium (LA), low septal puncture, or severe mitral valvular and subvalvular stenosis leading to prolonged procedure time or failure of PTMC procedure...

Percutaneous mitral valve repair (PMVR) using the MitraClip system (Abbott, Abbott Park, IL, USA) is an innovative method allowing treatment of mitral regurgitation (MR) for patients that are not accessible by conventional operation. Thrombogenicity in the left atrium (LA) in general is increased in the presence of atrial fibrillation and mitral valve disease. We observed in a patient who underwent PMVR an acute change in thrombogenicity in the LA with thrombus formation in the left atrial appendix (LAA) immediately after clip placement...

Spontaneous coronary artery dissection is a rare but important cause of acute coronary syndrome. Its relevance for women during the puerperium mandates awareness and understanding amongst obstetric healthcare professionals. The aetiology of the increased risk in pregnancy has not been fully elucidated, but include medial eosinophilic angitis, pregnancy-induced degeneration of collagen in conjunction with the stresses of parturition, and rupture of the vasa vasorum. The risk of mortality necessitates prompt diagnosis, usually by angiography...

Mitral regurgitation is the most common valve disorder in the Western world, and although surgery is the established therapeutic gold standard, percutaneous transcatheter mitral interventions are gaining acceptance in selected patients who are inoperable or at an exceedingly high surgical risk. For such patients, multidetector computed tomography (MDCT) can provide a wealth of valuable morphological and functional information in the preoperative setting. Our aim is to give an overview of the MDCT image acquisition protocols, post-processing techniques, and imaging findings with which radiologists should be familiar to convey all relevant information to the Heart Team for successful treatment planning...

There is scarcity of evidence regarding antiplatelet and anticoagulant therapy in patients with prosthetic valves undergoing percutaneous coronary intervention (PCI). Our goal was to compare clinical outcomes between patients with mechanical or bioprosthetic valves undergoing PCI. The study population comprised patients with either a bioprosthetic or mechanical heart valve in the aortic and/or mitral position undergoing PCI between January 2003 and July 2017. Demographics, admission, and discharge medications as well as procedural details were documented...

Chronic mitral regurgitation (MR) remains a common cardiovascular condition resulting in significant morbidity and mortality. With an aging population, increasing trends for both primary (degenerative) and secondary (functional) MR have become apparent. Although the gold standard remains surgical intervention with mitral valve repair/replacement, comorbid conditions have steered the development of less invasive technologies to mitigate perioperative surgical risk. Transcatheter mitral valve repair using a percutaneous edge-to-edge technique is the most widely available choice at present...

Aortic stenosis and mitral regurgitation are increasingly treated by percutaneous interventions including transcatheter aortic valve implantation (TAVI) and several mitral valve repair techniques, changing the landscape of valvular therapies in which surgery was predominant. Several randomised studies on TAVI have led to the use of this procedure in patients at intermediate or higher operative risk and have set strong foundations for future trials aiming to expand indications or to overcome several residual issues with TAVI...

Background In patients who have chronic heart failure with reduced left ventricular ejection fraction, severe secondary mitral-valve regurgitation is associated with a poor prognosis. Whether percutaneous mitral-valve repair improves clinical outcomes in this patient population is unknown. Methods We randomly assigned patients who had severe secondary mitral regurgitation (defined as an effective regurgitant orifice area of >20 mm2 or a regurgitant volume of >30 ml per beat), a left ventricular ejection fraction between 15 and 40%, and symptomatic heart failure, in a 1:1 ratio, to undergo percutaneous mitral-valve repair in addition to receiving medical therapy (intervention group; 152 patients) or to receive medical therapy alone (control group; 152 patients)...

Significant paravalvular leak (PVL) complicates between 6% and 15% of valve replacements and can result in heart failure and hemolysis. Paravalvular leak can be effectively treated with repeat surgery; however, these procedures are associated with significant operative morbidity. Percutaneous PVL closure is increasingly being utilized as the first line therapy for symptomatic patients, but efficacy may be limited by the lack of dedicated closure devices. Areas covered: This article will review the etiology and prevalence of PVL, discuss outcomes with surgical closure, describe the mounting data supporting percutaneous interventions, and highlight areas for future research emphasizing the need for new dedicated closure devices...

The Old-Age Heart Abstract. Knowledge of cardiovascular changes in old age and their therapeutic options is important. Old age can lead to hypertrophy of the left ventricle, diastolic dysfunction, heart valve changes and pulmonary hypertension. Patients often develop arterial hypertension. Valvular changes are common in people over 100 years of age (aortic stenosis and mitral insufficiency). The risk of coronary heart disease is 35 % for men and 24 % for women. In old age, sinus node dysfunction and atrial fibrillation are common...

In the assessment of cardiovascular disease, the clinical significance of left atrial (LA) pressure-volume relations has largely been overlooked in contrast to left ventricular (LV) compliance. However, LA compliance has recently gained more attention. Net atrioventricular compliance ( Cn ), a joint measure of LA and LV compliance, can be calculated non-invasively by a previously validated method using parameters from standard echocardiography. Compliance measurement may be of relevance in selected clinical settings...
