Methods: In this retrospective observational designed study, we retrieved hospital records of patients with a surgical history of mechanical or biological prosthetic valve replacement and who subsequently underwent transcatheter mitral paravalvular leak closure (TMPLC).

Coronary fistulae may lead to coronary steal phenomenon or considerable volume overload on the cardiac chambers, causing significant hemodynamic problems. Coronary fistulae can be closed either surgically or percutaneously. Percutaneous closure is frequently performed with coil embolization or a vascular plug.

Percutaneous closure of atrial septal defects is accepted as a safe and effective treatment method. Device embolization is a rare, but potentially fatal complication. While embolized devices are typically removed surgically, in eligible cases, they can also be removed percutaneously at an experienced center.

Introduction: The arteriovenous (AV) loop is recommended when further support is needed during paravalvular leak (PVL) closure.

Aim: We report the feasibility and safety of mitral PVL closure without constructing an AV loop, based on a single-centre experience.

Material And Methods: Fourteen patients with mitral valve replacement (MVR) who had New York Heart Association (NYHA) class III-IV dyspnoea or NYHA class II symptoms with significant haemolytic anaemia caused by severe or moderate-to-severe paravalvular regurgitation and who underwent transcatheter PVL closure (TPVLC) between May 2014 and February 2017 were enrolled.

Introduction: Increasing numbers of complex percutaneous coronary interventions have been accompanied by various intra-procedural complications. The fracture and embolization of devices or their fragments are potentially life-threatening situations, depending on the site of embolization. Different non-surgical methods to handle embolic complications have been proposed for different clinical situations.

Objective: The present study was designed to determine the effects of tirofiban (Tiro) infusion on angiographic measures, ST-segment resolution, and clinical outcomes in patients with STEMI undergoing PCI. Glycoprotein (GP) IIb/IIIa inhibitors are beneficial in ST-segment elevation myocardial infarction (STEMI) patients undergoing percutaneous coronary intervention (PCI), while the most effective timing of administration is still under investigation.

Methods: A total of 1242 patients (83.

Introduction: The Kounis syndrome and acute myocarditis are two distinct clinical entities, which could share nearly the same symptomatology as well as ECG (electrocardiography) and laboratory findings.

Case Presentation: First case was a 39-year-old male presented with acute chest pain and inferolateral ST elevation on ECG. The second case was a 29-year-old male presented with chest pain and diffuses ST elevation.

Peripartum cardiomyopathy (PPCM) is a form of idiopathic dilated cardiomyopathy affecting women in late pregnancy or early puerperium. Although initially described in the late 1800s, it has only recently been recognized as a distinct cardiac condition. The reported incidence and prognosis varies according to geography.

The exact pathophysiology of slow coronary flow (SCF) phenomenon, characterized by delayed opacification of coronary arteries during coronary angiography, is still unknown, although endothelial dysfunction, inflammation, vasomotor disorders and atherosclerosis are shown. The present study was conducted to investigate whether there is a coagulation pathway abnormality in patients with SCF measuring plasma factor XI and XII activity. The study included 55 patients with angiographically proven SCF (group I) and 40 individuals with normal coronary flow (NCF, group II).

The authors investigated the prognostic relevance of serum carbohydrate antigen 125 (CA125) levels in nonischemic dilated cardiomyopathy (NICMP) and assessed whether increased levels relate to the degree of functional mitral regurgitation (FMR). Seventy-seven patients with NICMP were enrolled and followed-up for 10 ± 2 months in this prospective study. Receiver-operating characteristic analysis established a cutoff CA125 value of 25 U/mL for predicting mortality.

A 32-year-old woman underwent transcatheter closure of a secundum type atrial septal defect with the Amplatzer device. The procedure was started under premedication with aspirin, clopidogrel, and heparin. During the procedure, a highly mobile thrombus attached to the left atrial disc of the device was detected by transesophageal echocardiography (TEE).

Background: It has long been speculated that mobile phones may interact with the cardiac devices and thereby cardiovascular system may be a potential target for the electromagnetic fields emitted by the mobile phones. Therefore, the present study was designed to test possible effects of radiofrequency waves emitted by digital mobile phones on cardiac autonomic modulation by short-time heart rate variability (HRV) analysis.

Methods And Results: A total of 20 healthy young subjects were included to the study.

Background: The aim of this study was to evaluate the prognostic value of different fractional flow reserve (FFR) cutoff values and corrected thrombolysis in myocardial infarction frame (TIMI) count (CTFC) measurements in a series of consecutive patients with moderate coronary lesions, including patients with unstable angina, myocardial infarction, and/or positive noninvasive functional test findings.

Methods: We included 162 consecutive coronary patients in whom revascularization of a moderate coronary lesion was deferred based on a FFR value ≥0.75.

Several previous studies suggest that myocardial bridging (MB) is associated with ischemia and rhythm disturbances. We sought to examine exercise-induced changes in P wave duration and dispersion (PWD), the markers of atrial conduction abnormalities in patients with isolated MB of left anterior descending artery (LAD) and control subjects. Eighteen patients with MB of LAD (group-I) and 22 subjects with angiographically demonstrated normal coronary arteries (group-II) underwent treadmill exercise testing.

Article Synopsis
  • The study examines how smoking affects the function of the left and right ventricles of the heart using Doppler imaging techniques in 20 healthy individuals.
  • Significant changes in diastolic function parameters, such as mitral and tricuspid inflow velocities, were observed 30 minutes after smoking a cigarette.
  • Results indicate that acute smoking has a negative impact on both the left and right ventricular function, emphasizing the immediate cardiovascular risks associated with smoking even in healthy nonsmokers.

The authors sought to determine left ventricular functions by conventional and tissue Doppler imaging in patients with isolated coronary artery ectasia and controls. Peak early (E) and late (A) mitral inflow velocity, E/A ratio, E deceleration time, and isovolumetric relaxation time were obtained. Peak systolic velocity (Sm), diastolic early (Em), and late (Am) velocities were measured by tissue Doppler imaging.

Coronary artery ectasia (CAE) is frequently considered as a form of coronary artery disease. Cardiovascular risk factors were determined in a patient population with CAE. The 51 patients with isolated CAE (group 1), 61 patients with CAE coexisting with significant coronary stenosis (group 2), and 62 subjects with significant coronary stenosis (group 3) were included in the study, and the distribution of cardiovascular risk factors was compared.

Acute cigarette smoking enhances adrenergic activity and thus may be associated with hemodynamic changes in the cardiovascular system. In this study, the acute effect of cigarette smoking on heart rate variability (HRV) was studied. Fifteen subjects were included in the study.

The slow coronary flow (SCF) phenomenon is often considered to be an incidental angiographic finding; however, several reports have shown it to be associated with cardiac events. In this study we aimed to assess P-wave duration and dispersion (PWD) in patients with SCF and to compare it with that of healthy subjects. Thus, 40 patients with angiographically proven SCF and otherwise normal coronary arteries (group 1) and 36 sex-age-matched healthy subjects (group 2) were included in this study.

Myocardial bridging (MB) is a congenital anomaly of coronary arteries and its functional significance remains controversial. Using the TIMI frame count (TFC) method, the authors investigated whether the coronary blood flow velocity is decreased in MB. The study included 18 patients (group 1; 12 men and 6 women; mean age 50 +/-6 years) who had angiographically proven MB and otherwise normal coronary arteries and 20 subjects (group 2; 13 men and 7 women; mean age 50 +/-7 years) with normal-appearing coronary arteriograms.
