The other strategies for combining PCI with thrombolytic therapy are the rescue PCI (ischemia driven PCI) and facilitated PCI. Assent 4 and Finesse trials [...]

Generally closure of atrial septal defect (ASD) is done in children and young adults. Benefits of device closure of ASD in older patients are not well documented. A recent study involving 23 patients with ASD and aged 50 – 91 years, having ASD size between 16 to 36 mm reported favorable cardiac remodeling and improvement [...]

Endovascular repair of abdominal aortic aneurysm (AAA) is an evolving modality of treatment. Conventional repair of AAA was surgical. A recent study published in NEJM compared endovascular repair with open surgical repair. This randomized study involved over 1200 patients from 1999 to 2004 in 37 hospitals in the United Kingdom. They were followed up till [...]
