Same symptoms and causes as weight, gain, ankle edema, and right upper quadrant pain. Less common symptoms
Paroxysmal nocturnal dyspnea, orthopnea, and hemoptysis (sign of pulmonary venous congestion): this symptoms are less frequent in Lutembachers syndrome and are more associated with MS and small ASD or patients who develop reverse Lutembachers syndrome. This symptom is caused by mitral stenosis. Related disorders

Ventricular Septal Defect
Mitral regurgitation
Ebstein disease

Causes
Lutembacher is caused indirectly by heart damage or disorders. Lutembachers syndrome is caused by either birth defects where the heart fails to close all holes in the walls between the atria or from an episode of rheumatic fever where damage is done to the heart valves such as the mitral valve and resultant in an opening of heart wall between atria. With Lutembachers syndrome, a fetus or infant is usually seen to have a hole in their heart wall (interatrial) separating their right and left atria. Normally during fetal development, blood bypasses the lungs and is oxygenated from the placenta. Blood passes from the umbilical cord and flows into the left atrium through an opening called the foramen ovale; the foramen ovale is a hole between the two atria. Once a baby is born and the lungs begin to fill with air and the blood flow of the heart changes, a tissue flap (somewhat like a trap door) called the septum primum closes the foramen ovale or hole between the two atria and becomes part of the atrial wall.
Zolmitriptan, sold under the brand name Zomig among others, is a triptan used in the acute treatment of migraine attacks with or without aura and cluster headaches. It is a selective serotonin receptor agonist of the 1B and 1D subtypes. It was patented in 1990 and approved for medical use in 1997. Medical uses
Zolmitriptan is used for the acute treatment of migraines with or without aura in adults. Zolmitriptan is not intended for the prophylactic therapy of migraine or for use in the management of hemiplegic or basilar migraine. Zolmitriptan is available as a swallowable tablet, an oral disintegrating tablet, and a nasal spray, in doses of 2.5 and 5 mg.  People who get migraines from aspartame should not use the disintegrating tablet (Zomig ZMT), which contains aspartame.A 2014 Cochrane review has shown that zolmitriptan 5 mg nasal spray was significantly more effective than the 5 mg oral tablet.According to a study of healthy volunteers, food intake seems to have no significant effect on the effectiveness of Zolmitriptan in both men and women.Off-label Uses:

Acute treatment of cluster headaches—Level A recommendation from the American Academy of Neurology
Acute treatment of menstrual migraine

Adverse reactions
As for cardiovascular side effects, zolmitriptan can increase systolic blood pressure in the elderly and increase diastolic blood pressure in both the elderly and young people. Additionally, there is the side effect of a dose-related increase in sedation.
