Introduction: Surgical interventions because of mitral valve disease have been ascribed since 1951. Many changes within mitral valve replacement have passed including closed and open mitral commissurotomy, mitral valve repair operations implantation of mechanical, biological heart valve and finally use of mitral valve homograft. Despite changes in chirurgical tactics and medico-technical environment, mitral valve homograft implantation remains one of the most complex surgical interventions. Surgical and technical details of mitral valve homograft implantation are discussed.
Objective: to estimate technical difficulties and anatomical positioning of mitral valve homograft considering a spectrum of indications of mitral valve replacement.
Case Report: 62-year-old woman 26 years ago underwent mitral valve replacement with Starr-Edwards mitral valve prosthesis, because of rheumatic heart disease by homograft. Due to malfunction of the mitral valve prosthesis, and progressive left ventricular failure patient was reoperated on 26(th) of February 2002. Fresh antibiotic preserved mitral valve homograft was implanted. Surgical techniques were guided using left ventricle size measurement indicated by echocardiography.
Results: The technique described by Acar/Carpentier was used except of mitral valve annuloplasty ring implantation. Peri- and early postoperative period was free of homograft related complications. The left ventricle function was improving and the heart size decreased dramatically during first postoperative week.
Conclusion: The most important peculiarities for mitral valve homograft implantation are echocardiography data and intraoperative left ventricle measurements. Homograft implantation techniques are rather demanding therefore indications for mitral valve replacement have to be selected carefully and should be based on the presence of severe mitral valve dysfunction in order to achieve best hemodynamic results and prevent patient from anticoagulation therapy.

Mitral annular calcification (MAC) is a common finding, especially among the elderly or patients undergoing hemodialysis. Caseous calcification of the mitral annulus (CCMA) is a rare MAC variant with liquefied material at the calcified annulus. Surgical management of CCMA often involves wide excision and debridement, increasing the risk of perioperative stroke.

Background: Although rare, embolization of left atrial appendage occlusion (LAAO) devices carries a significant morbidity and mortality burden.
Case Summary: An asymptomatic 77-year-old woman with inability to tolerate anticoagulation due to gastrointestinal bleeding presented for 45-day transesophageal echocardiography following LAAO with a Watchman device, which demonstrated incidental device migration to the left ventricular outflow tract (LVOT). Percutaneous extraction was performed using a novel technique with rat tooth/alligator forceps to successfully retrieve the Watchman from the LVOT using a transaortic approach.

West German Heart and Vascular Center, Department of Cardiology and Vascular Medicine, University Hospital Essen, Essen, Germany.
Background: Mitral valve transcatheter edge-to-edge repair (M-TEER) is increasingly applied in patients with high surgical risk. We aimed to evaluate whether the PASCAL system can be applied in an all-comers cohort irrespective of the underlying anatomy and whether technical features influence therapeutic success.
Methods: In this prospective, observational study we enrolled consecutive patients (n = 80) with mitral regurgitation (MR) 3+ and 4+ scheduled for M-TEER.

Background: Heart injuries following polytrauma (PT) are identified as a predictor of poor outcome. The diagnostic algorithm of cardiac damage after trauma consists of the systemic measurement of cardiac damage markers, a 3-channel ECG and if there are any suspicious findings, the conduction of a transthoracic echocardiography (TTE). The aim of this study was to implement a systematic analysis of cardiac function using TTE in PT-patients.

Background: Atrial secondary mitral valve regurgitation (ASMR) is a distinct anatomical subset of secondary mitral regurgitation (SMR). Evidence of the effect of transcatheter edge-to-edge repair (TEER) on left atrial (LA) anatomy and function, especially reverse remodelling (LARR), is still sparse.
Methods And Results: We retrospectively evaluated all consecutive patients treated with TEER for mitral regurgitation (MR) in our centre between January 2013 and October 2023.
