Longitudinal stent deformation is defined as shortening or elongation of the stent along its longitudinal axis after deployment. It is under-recognized on angiography, and imaging- based studies have reported an incidence of up to 1%. The etiology includes damage by the guiding catheter or secondary devices such as postdilation balloons, imaging catheters, additional stents, or wire entanglement. Deformation can occur with all stent platforms. In the present case, forceful removal of the trapped guidewire led to the guide being sucked into the LAD and deforming the stent.

A 12-year-old boy with complex cyanotic congenital heart disease with single-ventricle physiology was planned for univentricular repair. Aortopulmonary collateral occlusion using thrombotic embolization coils was planned, but during the procedure, there was perforation of an aortopulmonary collateral arising from the descending thoracic aorta. The teaching point from this case is that all aortopulmonary collaterals do not necessarily need to be occluded; when occlusion is performed, coils must be appropriately sized.

A 25-year-old man came to our clinic with the complaints of exertional palpitations and dyspnea. He had skeletal features suggestive of Marfan's syndrome. Contrast-enhanced computed tomography confirmed aneurysmal dilation of the aortic root and the proximal part of the ascending aorta. The patient was advised to undergo Bentall procedure for replacement of the aortic valve, aortic root, and ascending aorta. Marfan's syndrome is a connective tissue disorder with autosomal-dominant inheritance. Patients have a predisposition for progressive aortic root and ascending aortic dilation, and should undergo periodic echocardiographic monitoring.

Coronary-cameral fistula (CCF) is a rare congenital communication between a coronary artery and a cardiac chamber or a great vessel. Most patients are asymptomatic and these lesions are incidentally detected during coronary angiography, with the reported incidence being up to 0.2%. The most frequent draining sites are right ventricle, right atrium, and pulmonary arteries, with less frequent drainage to the left side of the heart. The majority of CCFs are hemodynamically inconsequential and do not require treatment. However, when large, these lesions can cause myocardial ischemia by causing coronary steal or high-output heart failure, and should be treated. Treatment modalities include transcatheter closure with embolic agents (microcoil or gelfoam) and surgical ligation. Choice of therapy is governed by size of the CCF, tortuosity of the feeder channel, size of the communication to prevent embolization, and concomitant coronary artery disease.

During inflation of the Inoue balloon during a balloon mitral valvotomy, indentation and compression of the Inoue balloon was seen. This is indirect evidence of severe subvalvular disease.
