Serotonin is released by activated platelets and may act as a mediator to initiate or sustain certain unstable syndromes of ischemic heart disease in humans. To determine whether or not serotonin concentration increases across the coronary bed in patients with severe, limiting angina, we measured central aortic and coronary sinus serotonin concentrations by a sensitive radioenzymatic assay in 3...

We report a case of successful treatment patient with multiple stab and cut wounds chest abdomen which resulted in the injuries venous coronary sinus abdominal organs. Surgical wound revision antishock unit, priorities surgical accesses (thoracotomy laparotomy) allowed timely cure injury. A key feature our is trauma. Coronary suturing closed heart surgery technically difficult. It has potential...

It is well-known that respiratory activity influences electrocardiographic (ECG) morphology. In this article we present a new algorithm for the extraction of respiratory rate from either intracardiac or body surface electrograms. The algorithm optimizes selection of ECG leads for respiratory analysis, as validated in a swine model. The algorithm estimates the respiratory rate from any two ECG l...

Aneurysms of the sinus of Valsalva are very rare and mostly located in the right coronary sinus. They might course with dyspnea, fatigue, and acute coronary syndromes. We present herein an extremely rare case report of a 61-year-old woman diagnosed with external left main coronary compression by a giant aneurysm of the left sinus of Valsalva, which was successfully managed with percutaneous cor...

OBJECTIVES This study sought to determine the feasibility of coronary sinus flow velocity analysis by transesophageal Doppler echocardiography for estimation of coronary flow reserve in patients with syndrome X and patients with coronary artery disease. BACKGROUND Coronary flow reserve provides useful information in patients with coronary artery disease and patients with syndrome X. Current m...

This paper describes a case of a 44-year-old male patient previously healthy admitted with an unusual spontaneous acute bacterial pericarditis associated with coronary sinus mass. Two-dimensional echocardiography showed large loculated pericardial effusion with signs of diastolic restriction and an image suggesting vegetation in topography of the right atrium coronary sinus. Pericardial drainag...

In 19 children with Kawasaki disease without any cardiac sequelae the coronary sinus was cannulated via the femoral vein with a specially designed flow catheter and coronary sinus blood flow was measured by the continuous thermodilution method. There was a statistically significant positive correlation between coronary sinus blood flow and age, body surface area, and left ventricular mass, but ...

OBJECTIVE To discuss geometric factors, which may influence long-term results relating to homograft competence following the Ross procedure, we describe the 3D morphology of the pulmonary and aortic roots. MATERIALS Measurements were made on 25 human aortic and pulmonary roots. Inter-commissural distances and the heights of the sinuses were measured. For geometrical reconstruction the three c...

OBJECTIVES The purpose of this study is to characterize the clinical profile and identify clinical markers that would enable the detection during life of anomalous coronary artery origin from the wrong aortic sinus (with course between the aorta and pulmonary trunk) in young competitive athletes. BACKGROUND Congenital coronary artery anomalies are not uncommonly associated with sudden death i...

A persistent left superior vena cava (PLSVC) was present in a 74 year-old man with dilated cardiomyopathy undergoing implantation of a cardiac resynchronization therapy device with defibrillator (CRT-D). A dual-coil active-fixation defibrillator lead was positioned in the right ventricular apex, followed by a SonR active fixation lead in the right atrial free wall. The coronary sinus lead was a...
