We present a novel technique for resolving the problem of radical size mismatch at the time of orthotopic transplantation. A 48-year-old man presented with chronic rheumatic heart disease and a giant left atrium. Twenty-three years before, he had undergone mitral valve replacement with a mechanical prosthesis. At the time of the repeated intervention, the volume of his left atrium was 350 mL. Surgical features of the transplantation included approximation of the pulmonary vein ostia by gathering sutures intentionally, in order to decrease the area of the left atrial posterior wall and thereby enable appropriate coaptation with the donor left atrium. After the operation, left atrial volume had been reduced to 60 mL.

Background: Imaging both electrical and mechanical cardiac function can better characterize cardiac disease and improve patient care. Currently, there is no noninvasive technique that can simultaneously image both electrical and mechanical function of the whole heart at the point of care. Here, our aim is to demonstrate that high volume-rate echocardiography can simultaneously map cardiac electromechanical activation and end-systolic cardiac strain of the whole heart in a single heartbeat.

There is a controversy whether histamine H-receptor activation raises or lowers or does not affect contractility in the human heart. Therefore, we studied stimulation of H-receptors in isolated electrically stimulated (one beat per second) human atrial preparations (HAP). For comparison, we measured force of contraction in left atrial preparations (LA) from mice with overexpression of the histamine H-receptor in the heart (H-TG).

Background: The vertical vein (VV) ligation during the total anomalous pulmonary venous return (TAPVR) correction is still controversial. Our study aimed to define the potential risk factors for VV persistence and their percutaneous occlusion.
Methods: The retrospective cohort study included 40 patients (26 males) with TAPVR treated at the tertiary referral center from 2005 to 2024.

Recently published data suggested significantly lower pacing-induced cardiomyopathy (PICM) incidence with conduction system pacing (CSP). Because most data evaluated only the impact on the left ventricle, this study aimed to assess changes in echocardiographic parameters of morphology and function for all heart chambers in patients with baseline preserved and mid-range LVEF over a medium-term follow-up period after CSP. A total of 128 consecutive patients with LVEF > 40% and successful CSP for bradyarrhythmic indication were prospectively enrolled.

Aim: Percutaneous vertebroplasty is generally considered a safe procedure, however, cases of cardioembolism and cardiac perforation have been reported.
Case Presentation: A 69-year-old woman was referred to our emergency department after an outpatient echocardiogram revealed a "thrombus-like" formation involving the right heart. Two weeks before she had undergone percutaneous vertebroplasty of the third to fifth lumbar vertebrae due to osteoporotic fractures.
