Injury to the coronary circulation during percutaneous interventions is an existent risk. One of these is coronary artery perforation that can have grave consequences. Fortunately, this is rare and overall there is a declining incidence of complications due to technological advances and extensive experience over time.

The SYNTAX (Synergy Between PCI With TAXUS and Cardiac Surgery) II score has been designed to overcome the limitations of the purely angiographic SYNTAX I score by including clinical parameters and comorbidities. It has not been tested extensively in "real-world" PCI patients, outside of randomized clinical studies.

This is a case of a 54-year-old female with a history of mechanical aortic valve replacement who presented in cardiogenic shock. Her primary care provider started her on rivaroxaban for anticoagulation therapy. An urgent transesophageal echocardiogram revealed a significant gradient and thrombosis on one leaflet of the valve that was immobile.

Pulmonary vein (PV) ostial occlusion with cryoballoon is classically assessed using PV angiography. A pressure-guided technique to assess ostial occlusion has been evaluated in small cohorts with mixed results.

View Article and Find Full Text PDFTakotsubo cardiomyopathy, also called "broken heart" syndrome or apical ballooning syndrome, is a reversible cardiomyopathy characterized by left ventricular dysfunction and ballooning of the left ventricular apex on imaging during systole. It predominantly occurs in post-menopausal women and is commonly associated with emotional or physical stress. Patients commonly present with chest pain and electrocardiographic evidence of ST segment elevation or T-wave-mimicking acute coronary syndrome, but with an absence of angiographic evidence of obstructive coronary disease.

Q fever is a zoonotic disease with a reservoir in mammals, birds, and ticks. Acute cases in human beings can be asymptomatic, or they can present with a flu-like illness, pneumonia, or hepatitis. Approximately 5% of cases progress to chronic Q fever.

Diagnosis is confirmed by a dissection flap that is seen on coronary angiogram in the absence of underlying coronary atherosclerosis. New techniques in intra-coronary imaging such as intravascular ultrasound (IVUS) and optical coherence tomography (OCT) are useful in diagnosing SCAD.

With recent advances in the field of percutaneous coronary interventions (PCI), angioplasty and stenting of the unprotected' LM has been performed in patients at high surgical risk. This is a challenging intervention as a large area of myocardium is at risk during the procedure.

However, the roles of cardiac rhythm and lead-placement duration in the development of severe tricuspid regurgitation are unclear. We reviewed echocardiographic data on 26 consecutive patients who had severe tricuspid regurgitation after permanent pacemaker or AICD placement; before treatment, they had no organic tricuspid valve disease, pulmonary hypertension, left ventricular dysfunction, or severe tricuspid regurgitation.

The majority of pericardial cysts are asymptomatic and are found incidentally. Symptomatic pericardial cysts present with dyspnoea, chest pain, or persistent cough.
View Article and Find Full Text PDFTakotsubo cardiomyopathy is an acute cardiac syndrome characterized by transient regional wall motion abnormalities of the left ventricular apex or midventricle. Patients often present with chest pain or dyspnoea, ST-segment elevation, and minor elevations of cardiac enzyme levels. Takotsubo cardiomyopathy has been associated with severe emotional or physical stress such as severe burns, spinal cord injury, subarachnoid haemorrhage, and multiple traumas.

MANE, such as post-PCI bleeding and contrast nephropathy, adversely influence survival, but are not recognized as a standard composite of complications. We assessed the feasibility and prognostic utility of deriving a composite of MANE.
