    Abstract Transesophageal echocardiography (TEE) with agitated saline contrast ("bubble study") is the gold standard for detection of patent foramen ovale (PFO). Standard provocative maneuvers help facilitate right-to-left shunting necessary for diagnosing PFO but may be difficult to implement during TEE. Hypovolemia related to preprocedural fasting may challenge detection of PFO in TEE, and additional optimization measures such as fluid replenishment with passive leg raise (PLR) can enhance PFO detection. We present a 57-year-old male with history of cryptogenic stroke and stubborn PFO which during TEE bubble study responded only to ample fluid replenishment with PLR following a period of prolonged preprocedural fasting.

    Abstract Parachute mitral valve (PMV) is a rare congenital cardiac valvular anomaly often associated with other congenital cardiac defects, particularly Shone's complex, but may infrequently occur in isolation. PMV and its variants are predominantly associated with mitral stenosis (MS) or rarely mitral regurgitation (MR). We present the case of a middle-aged female who was evaluated for a syncopal episode and found to have an atypical variant PMV with disproportionately long anterior mitral leaflet, bileaflet mitral valve prolapse, and mitral annular disjunction, without associated MS or MR. This is the first case report to highlight this particular constellation of findings.
