A rare case of Takotsubo cardiomyopathy.

Background: The recent advent of the cyclin-dependent kinase (CDK) 4/6 inhibitors has considerably evolved hormone receptor (HR)-positive/human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer treatment. Palbociclib, an orally administered pyridopyrimidine derivative, was the first CDK4/6 inhibitor to be introduced into daily clinical practice in combination with classic endocrine backbone, based on progression-free survival (PFS) benefit assessed in the pivotal PALOMA series of randomized clinical trials. Regarding its safety profile, neutropenia and leukopenia are the most common and well-defined adverse effects, while cardiac complications are rather scarce.

Cardiovascular complications of ribociclib in breast cancer patients.

Cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors have unprecedentedly advanced hormone-dependent breast cancer treatment paradigm. In the metastatic setting, ribociclib has consistently demonstrated survival benefit in pre-, peri-, and postmenopausal patients, conjugating efficacy with health-related quality of life preservation. Accordingly, the emergence of cardiac and/or vascular adverse events related to this novel targeted agent is gaining significant interest.

Cardiac resynchronization therapy in becker muscular dystrophy.

A 44-year-old male patient with known Becker muscular dystrophy and concomitant non-ischemic dilated cardiomyopathy presented to our department because of worsening heart failure and presyncope. Upon admission, the patient was in New York Heart Association functional class III despite optimal pharmacological treatment; his ECG showed sinus rhythm with left bundle branch block and a wide QRS complex. Non-sustained ventricular tachycardia was recorded during 24-hour Holter monitoring.

The impact of ultrasound contrast medium administration on the right ventricle in patients with heart failure.

Background: The purpose of the present study was to examine the effect of SonoVue™ on right ventricular (RV) dimensions and contractility in patients with heart failure.

Patients And Methods: Twenty-four patients were divided into two groups. Group A consisted of 15 patients with heart failure and group B (control) of nine patients without heart disease.
